Description

Technical field

The present invention relates to a fan-type chemical diffusion apparatus for volatilizing a chemical, to a technique for diffusing an active component of a volatile chemical such as an insecticide, insect repellent or anti-moth agent, aromatic chemical and deodorant ventilating a support body impregnated with the active component while using a fan-type blower powered by a motor.

More specifically, the invention relates to a fan type purification apparatus for repelling and exterminating

or exclude harmful or harmful insects including insects such as mosquitoes, flies, cockroaches, mites, ants and centipedes and insects that affect clothing such as derméstidos and moths ventilating a support body impregnated with an active component while using a type blower fan powered by a motor activated by a battery or batteries.

Prior art

There is known a volatilization and diffusion apparatus for fan-like chemicals that is designed to diffuse into the atmosphere, for example, in a room an active component of a volatile chemical such as an insecticide, insect repellent or anti-moth agent, product aromatic chemical and deodorant by the force of the wind.

This volatilization and diffusion apparatus of typical fan-type chemicals is provided with an air inlet to admit air from outside to inside the apparatus body and an air outlet to send out the admitted air. In the air flow duct between the air inlet and the air outlet are mounted a fan-type blower driven by a motor and an active component support body impregnated with an active component. A space is also provided in the device body to house a battery to power the motor and therefore the fan blower.

The body impregnated with active component is arranged either in the air flow duct between the air inlet and the fan or in the air flow duct between the fan and the air outlet. Therefore, the apparatus is of the type in which the rotation of the fan to send air causes the active component in the impregnated body to diffuse through the air outlet to the atmosphere.

JP5068459 discloses an apparatus for evaporating drugs, in which a bag of drugs is attached to a ventilator and rotated therewith.

As shown in JP U H06-4393A, another fan-type chemical diffusion apparatus is known, in which the fan in a fan-type blower itself contains a volatile chemical.

The typical fan-type chemical diffusion apparatus mentioned above is provided with the fan-type blower and the body impregnated with active component separately in the apparatus body and is formed with an air flow duct in the apparatus body. As a result, it is bound to have a complex structure and makes the device have a large size.

The requirement that the body impregnated with active component and the fan are arranged to effectively send air into, through and out of the body impregnated with active component tends to make the apparatus have a complex structure and a large size.

If the device must be powered by a battery, having to provide a space to house the battery in the device makes the device even more complete and larger.

It should be noted in particular that the site where the body impregnated with active component is placed determines the size of the apparatus and a degree of its complexity.

The fan-type chemical diffusion apparatus disclosed in JP U H06-4393A, by operating the fan effectively as the body impregnated with active component intends to solve the problem of how to effectively dispose and simplify the device structure. However, many problems remain unresolved, for example, with respect to unsatisfactory durability (eg, fragility) of the fan that must be realized by forming a limited impregnable amount (small amount) of an active component and, if the fan is of the type of replacement, time, work and cost involved in the replacement, which make the device have little utility and maintenance capacity.

As an example of the fan-type chemical diffusion apparatus that uses a fan-type blower, a first-class purification apparatus for repelling and exterminating or excluding a harmful or harmful insect that is designed to volatilize a device has also been disclosed. chemical product providing an air flow through the chemical by means of a fan blower driven by a motor. See, for example, JP P S53-14329A, JP U S61-182273A, JP U H06-75179A, WO96 / 04786, JP P H08-154554A, JP P H11-504627A and JP P H11-28040A.

As another example as disclosed in JP P H05-68459A, a second type purification apparatus has also been disclosed in which a volatile chemical is retained within the chemical diffusion fan that can be rotated to volatilize the chemical.

In addition, as another example, a third type of purification apparatus is known as disclosed in JP P H07-111850A, a third type of purification apparatus has been disclosed in which a support impregnated with a A chemical that also works to rectify a gas flow is arranged on the air intake side of a fan that can be rotated to cause an air flow created to volatilize the chemical.

The purification apparatus of the first type seems to lack specificity and seems to have many problems to be solved for practical use.

The purification apparatus of the second type is technologically concrete and practical but if it were put into practice it seems that it would lack flexibility. The need to make the retaining element larger in order to volatilize a greater amount of a chemical, proportionally increases the energy needed to drive the fan.

The purification apparatus of the third type is technologically concrete and practical but it is observed that it requires not only that the support be of greater area but that it has an adequate way to reduce air resistance as much as possible. As the analysis of the present inventors indicates, the idea of requiring that the body impregnated with active component be of greater area should be justified in order to volatilize a greater amount of the active component. However, it was found that the idea of requiring that you comply so as to reduce wind resistance as much as possible was very questionable.

To eliminate wind resistance means reducing wind pressure per unit area and this would reduce a force to separate the chemical from the support. Then, the phenomenon that the wind passes away from the support without sufficiently carrying the chemical, or a reduction in the concentration of chemical by unit air flow would take place. This is a loss in wind force and in other words a loss in motive energy.

In contrast, an air resistance that increases excessively would reduce the wind speed of a wind leaving the air outlet and lose the ability to carry the chemical away.

As an example of the purification apparatus using a fan-type blower, a fourth type of such apparatus has also been proposed that is designed to volatilize a chemical by providing air flow through the chemical by means of a fan-driven blower. by an engine See, for example, JP P S53-14329A, JP U S61-182273A, JP U H06-75179A, WO96 / 04786, JP P H08-154554 and JP P H11504627A.

In addition, as another example, a fifth type of purification apparatus has also been proposed as disclosed in JP P H11-28040A comprising a DC motor powered by a battery and a fan to be driven by the DC motor to provide an air flow through a chemical for volatilization.

The purification apparatus of the fourth type seems to lack the specificity to use a battery as a power source and seems to have many problems to be solved for practical use.

The purification device of the fifth type is an apparatus with a battery as a power source and is shown in its second apparatus that has a current consumption not exceeding 100 milliamps when the DC motor is not charged. However, it does not seem to take into account, for example, the efficient use of the battery to allow the chemical to volatilize for a prolonged period of time.

Therefore, a fan-type debugging apparatus is used to repel and exclude harmful or harmful insects as previously described located in a storage space in a house in order to operate for a long period of time or carried by a Worker for outdoor operation. Therefore, it is desired that the apparatus has the ability to volatilize a chemical for a long time without the need to change the battery.

Another example of the fan-type debugging apparatus is also known as disclosed, for example, in JP P H11-308955A.

This fan type purification apparatus has an apparatus body provided with a motor, a fan, a battery and a chemical retention element and can be operated to provide an air flow through the chemical retention element from the fan driving the engine with battery power to volatilize the chemical. It is shown that the engine is operated intermittently to iteratively have an air flow time period and an alternate stop time period, the stop time period being ten times or more as long as the flow time period. of air.

The fan-type purification apparatus referred to above is designed for use located in a storage space such as a closet or closet and is there to extend the purification component sufficiently within the enclosed space and can maintain its Enough efficiency for a long time.

However, the use of this type of device located in a space inhabited in a house proves to be insufficiently effective.

Methods of volatilization and diffusion of chemicals that use the force of a fan's wind to volatilize and diffuse a volatile chemical into the atmosphere are also known. For example, JP U S61182273A discloses the application of wind from the fan to a retention element body impregnated with a chemical having moderate air permeability, and JP P H07-11850A discloses the definition of a relationship between a permeability and the wind force of a fan.

To the present inventors to know, all retention element bodies or impregnated with chemical (bodies impregnated with active component) proposed to date in the prior art are bodies that are solidified and are monolithic. For this reason, they provide an effective means if the chemicals to be carried by them have a high vapor pressure and, therefore, are highly volatile. If there is a need to volatilize a chemical that is less volatile or difficult to volatilize or volatilize a large amount of the chemical at the same time, it is necessary to take a measure such as: (1) make the volatilization area of a body impregnated with chemical; (2) make the gaps larger in a body impregnated with chemical to facilitate the passage of wind; and intensify the fan outlet.

It has been discovered, however, that none of these measures can be taken without making the entire volume of the body impregnated with chemical larger, or without making the fan larger or without deteriorating energy efficiency. Especially, an increase in body size impregnated with chemical produces the following problems:

(one)

 Local changes in the air flow inside the body impregnated with chemical. Therefore, as it moves especially away from the wind blow outlet, the air flow per unit of time tends to be reduced by a resistance of the air that develops in the body impregnated with chemical. If the chemical-impregnated body is larger in the direction of the wind, the force of the wind that the chemical-impregnated body receives instantly varies from place to place. This leads to an imbalance of volatilization in the entire impregnated body and prevents the chemical from volatilizing in a stable manner.

(2)

 Even if the situation (1) develops, stable volatilization will be possible even for the body impregnated with solidified, monolithic chemical if the impregnated chemical is quickly made uniform in the body. However, increasing the size of the body impregnated with chemical makes the distance in which the chemical moves longer and requires a longer time for the chemical to become uniform in the body.

(3)

 An increase in body size impregnated with chemical due to the problem mentioned in (1) above also causes a decrease in air flow per unit of time from the air outlets (volatilization outlets) of the body receptacle impregnated with chemical, which leads to a decrease in the ability of the chemical to volatilize in a room and in turn to a decrease in the effectiveness of the chemical. To solve these problems, an attempt made to intensify the wind force of the fan is an attempt to waste energy and proved ineffective and inexpensive.

Accordingly, it is an object of the present invention to provide a fan-type chemical diffusion apparatus that can solve one or more of the problems mentioned above.

It is also an object of the present invention to provide a fan-type purification apparatus to repel and exterminate or expel a harmful or harmful insect that allows an active component to volatilize in a maximum amount with a minimum input power supply.

It is also an object of the present invention to provide a fan-type purification apparatus that operates with a battery that allows a chemical to volatilize for a prolonged period of time without the need to change the battery.

It is also an object of the present invention to provide a fan-type purification apparatus that can be used in an inhabited space, demonstrating sufficient efficiency and which can maintain sufficient efficacy for a prolonged period of time.

It is also an object of the present invention to provide a method of volatilization of chemical products that allows a volatile chemical that has an insecticidal, insect repellent or growth control function to diffuse and be dispersed stably by a wind force during a prolonged period of time for a variety of harmful or harmful insects, regardless of the vapor pressure of the chemical and the amount of volatilization that is intended for the chemical.

Description of the invention

A fan-type chemical diffusion apparatus according to claim 1 is provided according to the present invention.

This invention requires that a fan be uniquely provided with a hollow space adapted to house in it a mass or a body impregnated with active component and only requires that the apparatus body part have a space therein sufficient to accommodate the fan blower, and eliminates the conventional need to provide extra space to separately house an impregnated body with active component.

This structurally simplifies the interior of the device body and makes the device compact and small in size.

In addition, the elimination of the requirement to arrange the body impregnated with active component next to the fan blower in the body part of the apparatus, enhances its design flexibility.

In addition, it is found that the fan does not reduce its durability and can retain a sufficient amount of an active component.

In the previously established construction, the mass or body impregnated with active component is preferably fixed to one of said fan housing and the main body of the apparatus.

This specific construction allows the mass or body impregnated with active component to be placed without being able to rotate with the fan and be maintained without increasing the resistance to rotation of the fan, and therefore without creating a loss in its driving force.

In the construction set forth above, the mass or body impregnated with active component is preferably removably mounted in the hollow space.

This construction makes the apparatus economical because then it only requires that the mass or the body impregnated with active component be changed while leaving the fan intact.

Extensive and enthusiastic research and experiments carried out by the present inventors taking into account what has been established earlier in this document have revealed that there is a delicate balance between wind resistance and volatilization amounts of an active component and It has also led them to the fan-type debugging device mentioned below.

A fan type purification apparatus is provided to repel and exclude or expel a harmful or harmful insect with an active component containing at least one chemical having a vapor pressure of not less than 1.0 x 10-4 as the main component. mmHg at a temperature of 30 ° C and effective to act as an insecticide or acaricide or to control growth, or to hinder a hematophage, sting or feeding behavior of the insect, or to repel the insect, or effective to prevent any other damage due to insect, the apparatus having a mass or a body impregnated with active component adapted to retain and release the active component by volatilization, and including a fan-type blower powered to be driven by a motor, characterized in that: said mass or body impregnated with active component it is arranged on a wind inlet side of said fan type blower and is designed to provide r a resistance to wind force R which in terms of the proportion of current consumption E2 by said motor in the presence of said mass or body impregnated with active component with respect to the current consumption E1 by said motor in the absence of said mass or body impregnated with active component, ranges between 5 and 25% where R is expressed by the equation: R = 100 - E2 / E1 x 100.

This allows efficient use of a motor drive energy to volatilize a large number of active components, and provides the volatilization of a maximum amount of the active component and therefore a maximum extent of prevention against the damage of insects or bugs to a quantity Minimum input power.

Extensive investigations and experiments have been carried out by the present inventors by varying the air resistance index of the fan, size and weight of the fan and motor parameters in a varied manner and have led them to the following form of the purification apparatus of fan type

A fan type purification apparatus is provided to repel and exclude a harmful or harmful insect with an active component containing at least one chemical having a vapor pressure of not less than 1.0 x 10-4 mmHg as the main component. a temperature of 30 ° C and effective to act as an insecticide or acaricide or to control growth, or to hinder a hematophage, sting or feeding behavior of the insect, or to repel the insect, or effective to prevent any other damage due to the insect; the apparatus having a mass or a body impregnated with active component adapted to retain and release said active component by volatilization, and including a fan-type blower powered to be driven by a motor that is ignited by a battery, characterized in that said fan-type blower it comprises a fan that has: an air resistance f which when expressed by the current consumption I1 by said motor loaded with said fan divided by the current consumption Io by said motor when it is not charged with said fan, ranges from not lower to 1 but not more than 17; a size in a range between 20 mm and 100 mm in diameter; and a weight in a range between 1.5 grams and 8 grams, in which the values of the air resistance, size and weight of said fan are selected as mentioned above and additionally so that the current consumption by said motor charged with said fan has a current value so that the ratio of a period of time in which said fan can be operated by said battery with respect to the capacity of said battery is not less than 5%.

This allows an engine to be operated effectively to ventilate a mass or a body impregnated with active component for a prolonged approximate period of time without the need to change a battery and therefore the active component volatilizes during such an approximate long period of time. without the need to replace the battery.

The failure of the conventional fan-type purification apparatus if it is used located in an inhabited space to produce sufficient efficiency as mentioned hereinbefore, the present inventors reasoned as follows:

•

In contrast to a closet or closet in which the purification of the type with conventional fan can be used and that is usually opened or closed only twice a day or so in the morning and at night, an inhabited space has several visitors and It opens and closes frequently during the day, and therefore has a much larger air inlet and outlet than the storage space

•

For this reason, by making the period of time in which the air flow stops as long as ten times the period in which air is caused to flow, the purification agent (active component) is prevented from spreading and diffusing enough to an extent where satisfactory efficacy is obtained.

Extensive and enthusiastic research and experiments carried out by the present inventors taking into account these reasons have led them to the following form of fan-type purification apparatus:

A fan type purification apparatus is provided to repel and exclude a harmful or harmful insect with an active component containing at least one chemical having a vapor pressure of not less than 1.0 x 10-4 mmHg as the main component. a temperature of 30 ° C and effective to act as an insecticide or acaricide or to control growth, or to hinder a hematophage, sting or feeding behavior, of the insect, or to repel the insect, or effective to prevent any other damage due to the insect, the apparatus having a mass or a body impregnated with active component adapted to retain and release said active component by volatilization, and including a fan-type blower powered to be driven by a motor, characterized in that: said fan-type blower can be operated to operate in iteratively and stand alternately, the downtime period being no more than 9 (nine) times as long as the period of operation time, said period of stopping time being also a period of time in which a current or an amount of electricity that is not lost therein is greater than a current or an amount of electricity consumed in excess for said motor in said period of operating time.

This allows an apparatus if used located in an inhabited space to provide sufficient efficiency and retain this efficiency for a prolonged period of time.

In the invention set forth above, desirably:

These and other features, objects and advantages of the present invention will be more readily apparent to those skilled in the art from the following detailed description of the preferred embodiment thereof.

First, an explanation is given with respect to an apparatus according to the present invention.

As shown in Figures 1 and 2, the apparatus comprises a main body of apparatus or body part 1 which as a whole is in the form of a substantially rectangular box having its lateral part 2 and its other lateral part 3.

The first side part 2 is composed of a substantially rectangular side face plate 2a and first, second, third and fourth end face plates 2b, 2c, 2d and 2e which are continuous with the peripheral part of the side face plate 2a . Therefore, the first side part 2 is in the form of a substantially rectangular box with an open side face. Between the first and second end face plates 2b and 2c that are opposite each other and closer to the third end face plate d there is a partition plate 4 attached thereto, whose horizontal section is substantially shaped in the form of letter "U", and which subdivides the body part of apparatus 1 into a chamber that houses the fan-type blower 5 and a battery chamber 6.

The third end face plate 2d is formed with an opening 7 shown closed with a cover 8 for inserting and removing dry batteries 9 from the battery chamber 6 by opening the cover 8.

The other side part 3 is flat and removably joins an opening 10 formed by the first, second, third and fourth end face plates 2b, 2c, 2d and 2e. The other side part 3 is thus connected, for example, in a snap fit or hinged door fit.

A fan type blower 11 is shown arranged in the chamber that houses the fan type blower 5 and comprises a fan housing 12, a fan 13 and an electric motor 14.

The fan housing 12 comprising its side face plate 12a, another side face plate 12b and the peripheral face plate 12c has a recess 15 formed in a central area of the side face plate 12a so that it sinks towards the opening 10 to contain the motor 14 therein. The other side face plate 12b is formed with a large diameter hole 16 which is toroidal.

The peripheral face plate 12c is formed with a discharge or supply outlet 17 which is continuous with an air outlet 18 formed in the first end face plate 2b.

The fan 13 is configured in the form of a centrifugal fan, which comprises a rotating disk 13a and a large number of radially extending vanes 13b attached thereto closer to its periphery. The rotating disk 13a is formed closer to its center with a cylindrical and flatter part 19 and 20 forming a hollow that sinks towards the large diameter hollow 16, and providing a hollow annular space 21 between the cylindrical part 19 and the vanes 13b The hollow space 21 is opened so that it communicates with the atmosphere through an intake opening 22 between the large diameter gap 16 of the other side face plate 12b and the cylindrical part 19.

The engine 14 has its drive shaft 14a connected to the flat part 20 of the fan 13 and is driven to rotate the fan 13.

Loaded so that it can be discharged, in the hollow space 21 of the fan 13 there is an active component of the cartridge type or a mass or a support body 23 for the active component.

The active component support body or mass 23 includes a housing 24 that is hollow and toroidal in which a large number of granular or particulate processed articles 25 of active component are contained. When loading the body 23, the housing 24 can be inserted from the intake opening 22 in the hollow space 21 and then fixed in place by holding connecting pieces 24a provided for the housing 24 to the other side face plate 12b of the housing fan 12 by machine screws 26.

The housing 24 is formed with a large number of air outlets 27 opposite to the vanes 13b and air inlets 28 that are opposite to the air intake holes 29 formed in the other side element or part 3. The other side element 3 it is provided with an air flow guide 30.

In operation, the rotation of the fan 13 by the engine 14 causes air to be drawn from the atmosphere through the intake ports 29 and the air inlets 28 into the housing 24 and, the ventilation of the particulate processed items 25, It allows the chemical to volatilize and then propagate into the atmosphere through the air outlets 27, the discharge outlet 17 and the air outlet orifice 18.

Then, without rotating the mass itself or the body impregnated with active component 23, the fan 13 is prevented from increasing its resistance to rotation.

In addition, the ability to remove the mass or the body impregnated with active component 23 outside the hollow space 21 outside the body part of the apparatus 1 by removing the other side element 3 and loosening the machine screws 26 allows the component to be impregnated active or change the mass or support body 23, as desired.

An explanation is given below with respect to modifications of the embodiment of the invention.

Therefore, in the first place with respect to the direction of ventilation, although in the embodiment described above, air is drawn through a lower surface so that it flows out through a side surface of the fan-type blower 11 with its axis of rotation (i.e., the drive shaft 14a of the engine 14) adjusted to extend vertically, alternatively, air can be sucked, for example, through a side surface to flow out through another surface lateral, or aspirated through an upper surface so that it flows outward through a lateral surface of the fan-type blower 11 with the air inlet and outlet holes 29 and 18 properly rearranged.

Also, the shape of the apparatus can be altered according to its intended use. For example, it is possible to adjust the axis of rotation of the fan-type blower 11 (i.e., the drive shaft 14a of the motor 14) so that it extends in a transverse direction (front and rear), so as to make the apparatus longer vertically and suitable for placement in a vertical clearance.

For the fan 13 of the fan type blower 11 for use in the present invention, in order to change the air flow from an axial direction to a radial direction, use is made of a centrifugal fan in which a force is applied centrifuge to confer energy to the flow.

A centrifugal fan is preferable for the fan 13 because it has a large number of vanes that are of greater width and of less height, and structurally it does not have vanes but a hollow space in its central area.

A centrifugal fan is also preferable because it has high jet power and a relatively small size.

Illustrative are, for example, a turbo fan, a fan of aerodynamic vanes, a fan of limited load, a radial fan, a fan of multiple vanes, and so on.

It is also preferable that a centrifugal fan is placed as mentioned above in a spiral, conical or spiral casing designed to effectively join winds produced by rotating the fan and then letting them out.

In order to load the mass or the body impregnated with active component 23 in the hollow space 21 of the centrifugal fan mentioned above, it is also possible to use processed articles or a body or formed bodies that can be impregnated with a volatile chemical as active component.

Illustrative are, for example, items processed so as to have an active component coated thereon by spraying or the like, or such processed items housed in an air-permeable housing as in the case of Figures 1 and 2, or a body or formed bodies such as a synthetic resin containing an active component.

No limitation is imposed on the materials of which the processed items may be composed

or the body formed except that they must be able to completely contain an active component and that they must be able to release it when they are ventilated.

Illustrative of such materials are, for example, pulp, paper such as filter paper or card stock, a natural fiber such as cotton, wool or chingma, an artificial fiber such as polyester, nylon or polyolefin, a carbon fiber, a fiberglass, a ceramic, a synthetic resin such as polyolefin, polyvinyl chloride or high oil absorption polymer, nonwoven textile material and a porous natural material.

No limitation is imposed either on the conformation or configuration of the body impregnated with active component, except that the body must be arranged in the hollow space of the centrifugal fan. They are illustrative for the conformation and configuration, for example, circular, semicircular, square and polygonal frames, and a hollow toroidal body.

No limitation is imposed either on the size or geometry of the body impregnated with active component, except that the body should be easily disposed in that hollow space and that the body should not affect the fan rotating.

No limitation is imposed either on the thickness or length of the body impregnated with active component, which refers to the impregnating content of the active component, except that it can be sized to meet the intended use. The body may even be designed to have its length greater than the length of the hollow space.

Furthermore, as for the loading of the dough or the body impregnated with active component, although in the described embodiment it is shown that the housing 24 in which particulate processed articles 25 are packaged as the body impregnated with active component is to be inserted into the hollow space 21 in the centrifugal fan 13 and is to be attached to the fan housing 21, such a housing 24 can be attached directly to the main body part of apparatus 1, for example, by means of a fixing plate such As prepared separately. It is also possible to provide the main body part of apparatus 1 with an opening for insertion (for example, in an area of the air intake hole 29 on the other side part 3) so that the housing 24 can be inserted therethrough and then hold on like this.

In addition, the fastening means are not limited to a machine nut or nuts but can adopt adhesive or coating means. It is preferable that any such means is selected according to the particular shape of the body impregnated with active component designed for its intended use.

In addition, they are illustrative for the battery or battery 9 used to power the fan blower 11, for example, a primary battery or battery such as an alkaline dry cell, a dry manganese battery, a button cell battery, a air battery or a lithium ion battery, and a secondary battery or battery such as a nickelcadmium battery or a lithium ion battery.

An appropriate choice of a particular battery or battery may be made together with its class (for example, either alkaline or manganese, or type 1 or unit 2), its number and its connection mode (in parallel or in series) considering its conditions and period of use, the class of the motor and fan used.

The fan-type blower 11 for the drive can also be powered by commercial AC supply (for example, with 100 volts). Then, it will be necessary to provide the device externally or internally with an AC-DC converter.

In addition, a fan-type chemical diffusion apparatus according to the present invention is not limited to a specialized or exclusive apparatus as shown in Figures 1 and 2 but can be applied to any home or office electrical appliance using a fan. Centrifugal also, to endow it with the ability to repel and kill harmful or harmful insects, deodorize an unpleasant smell, and emanate a fragrance or aroma.

According to the described apparatus of the present invention, having the fan 13 configured to provide in its mass, volume and size a hollow space 21 adapted to house an impregnated body with active component 23 only requires that the apparatus body part 1 have a sufficient space therein to house the fan blower 11, and eliminates the conventional need to provide extra space to separately house the body impregnated with active component 23.

This structurally simplifies the inside of the device body and makes the device compact and small in size.

In addition, the elimination of the requirement of separately disposing the body impregnated with active component next to the fan blower in the body part 1 of the apparatus, enhances its design flexibility.

In addition, it is found that the fan does not reduce its durability and can retain a sufficient amount of an active component.

According to the described apparatus of the present invention, the body impregnated with active component 23 that does not rotate with the fan 13 is maintained so as not to increase the rotation resistance of the fan 13, and therefore does not create a loss in its driving force.

The described apparatus of the present invention is economical because it only requires that the impregnated body with active component 23 be changed while leaving the fan 13 intact.

An explanation is given below with respect to a fan-type purification apparatus for repelling and killing harmful or harmful insects.

Referring to Figures 3 and 4, the debugging apparatus has a body part 31 substantially in the form of a rectangular box, comprising an upper face plate 32, a lower face plate 33, a first pair of opposite side plates 34 and a second pair of side plates 35, which define and enclose their interior with them. A partition plate 36 is provided for subdivision with the side face plates 34 and 35, from this interior into an upper and a lower space or compartment 37 and 38.

The upper space 37 has a fan-type blower 40 mounted therein with an electric motor 39 to power the same. The fan blower 40 comprises a fan 41 and a fan housing 42, the latter serving to house and / or protect the fan 41, and / or to rectify a created wind and / or to intensify the wind force. In the illustrated manner, the fan 41 is constituted by a Silocco fan with the fan housing 42 having its air intake side in communication with an air intake hole 43 formed in the partition plate 36 and its outlet side in communication with an air discharge hole 44 formed in one of the second pair of side face plates 35.

The lower space 38 has a housing 45 for an impregnated body removably mounted therein opposite the air intake port 43.

The impregnated body housing 45 is composed of a material and / or has a conformation that stands out for its air permeability that allows air to pass smoothly through it.

The impregnated body housing 45 has an impregnated body with active component 46 located therein to house and / or protect it.

At least a part of the impregnated body housing 45 that comes into contact with the impregnated body 46 is comprised of plastic comprising at least one of polyester, polypropylene, polyvinyl chloride, ABS, polystyrene, AS, methacrylate resin , polyvinyl alcohol, EVA, phenolic resin, silicone resin, polyamide resin, polyacetal resin, polycarbonate resin and thermoplastic polyester resin.

The lower space 38 also has a battery or batteries 47 removably mounted therein, the battery or batteries 47 being used to drive the motor 39.

In operation, the operation of the fan 41 with the engine 39 causes air to be aspirated as indicated by the arrow a into the fan housing 42 past the impregnated body housing 45, the impregnated body 46 and the intake port 43

Air sucked into the fan housing 41 is allowed to flow outward, creating a wind that is rectified and / or whose wind strength is intensified in this way, through the outlet orifice 44 as indicated by the arrow b.

This allows an active component impregnated in the body impregnated with active component 46 to volatilize and then diffuse through the air outlet orifice 44 into the atmosphere.

For convenience, a value is established that may be referred to as "wind force resistance value"

A. When deriving a wind force resistance value, although it may be necessary to measure wind speed (air) or the amount of air flow directly, a method of measuring the amount of electric current consumption in the motor which varies according to the air resistance of the active component would result in less measurement error even if it is indirect. Therefore, in this case the latter method is adopted.

The described fan-type debugging apparatus should preferably be provided with an impregnated body housing designed to house and / or protect an impregnated body with active component considering performance and stability and safety in use.

In addition, the described fan blower should preferably be provided with a fan, a fan housing designed to house and / or protect the fan, and / or to rectify the air wind and / or to intensify the wind force of the air, and an electric motor.

The body impregnated with active component should preferably have a conformation or configuration that instead of being a honeycomb form that has an air or gas rectification function is a form of material that has a large effective area that is at least one material selected from the group consisting of a mass of granules, a mass of strips and a mass of chains, filaments or strands. It is also preferable from the viewpoints of the retention and / or release of the active component that the particulate material that forms the body impregnated with active component is composed of at least one material selected from the group consisting of cellulose, an absorbing agent of polymeric water, a polymeric oil absorption agent and a gel.

The active component is preferably an insecticide or a growth control agent that is effective for one or more kinds of insecticides but that does not harm men or animals.

The insecticides should preferably be pyrethroid insecticides of which at least one chemical selected from the group consisting of teraletrin, pralethrin, furamethrin, aletrin and emprntrine is particularly advantageous.

For growth control (inhibition) agents, at least one chemical that is selected from the group consisting of pyriproxyphene, methoprene and hydroprene is preferred.

For the fan as a source that produces wind power or force, preferably a Silocco fan and / or axial fan configuration is used. If a Silocco fan configuration is used, it is desirable that the desired fan housing be used to gather the winds around the fan.

In order to present a maximum effect of repellency and extermination of harmful or harmful insects at a minimum energy, preferably use is made of an energy saving type motor that has a current consumption of 100 mA or less under no load conditions with an applied voltage of 1.5 volts. In addition, the use of a battery or batteries as a power source for such an engine improves the maintenance capacity of an appliance in the sense that it does not choose a place for installation. The upper limit set to 100 mA or less for an allowable current consumption is based on the assumption that a period of time of at least 12 hours will be required for use with a unit 3 battery that has high properties of general use

In addition, the combination of an antioxidant agent and / or an ultraviolet absorption agent in the body impregnated with active component and / or the combination of an ultraviolet absorption agent in a body housing impregnated with active component will allow it to be used. a stable implementation over a prolonged period of time. It also allows outdoor use.

The end-point marking methods that are essential for the preparation of a chemical include a method of using a lipophilic anthraquinone dye for the body impregnated in case of being hydrophilic and using the phenomena that the color of the dye in If it is dissolved in the chemical it is recognizable and that when the chemical evaporates from the dye it enters the body to make its color unrecognizable. Also included is a method of using a color-changing pigment that is composed of an organic electron-releasing compound that changes color and a desensitizer, or an organic electron-releasing compound that changes color, a desensitizer and a color developer. A method is further included in which the sublimation rate of a sublimation agent is made to be substantially equal to the volatilization rate of the chemical. Although any one of these methods can be used individually, the use of a color change and a sublimation agent in combination will actually make the use felt and will therefore be preferred.

The sublimation rate can be adjusted to a value as required by adjusting the area of a ventilation opening that can be provided for a housing containing the sublimation agent.

As a wind or winds created by the rotation of the fan driven by the engine, it is also desirable for air to flow in the order of the air intake port, the body impregnated with active component, the fan, the fan housing and the air hole. air vent.

Also for the active components described, there is no limitation imposed on the use of the insecticides and / or repellants (insect repellents) listed below, in any combination with a proportion as desired.

For example, to kill insects, any one or more of a variety of volatile insecticides used to date can be used. Illustrative are pyrethroid insecticides, carbamate insecticides and organophosphorus insecticides. Pyrethroid insecticides are known to have high safety and have been used well.

A fan type purification apparatus was used as shown in Figures 3 and 4. As the body impregnated with active component, use was made of two masses impregnated with granules that were composed of 5 cellulose and had diameters of 4 mm and 2 mm, respectively [supplied by Rengo, KK with the trade name of Viscopar (spelled phonetically)], and a mass impregnated with strips that were made of paper cut in a size of 0.3 cm x 70 cm. Investigations were made of a relationship between the amount of impregnation or load and the values of resistance to wind force R that these bodies were supposed to have derived from the measured values of current consumption E2 of the motor. The results of the investigations are summarized in the

10 table 1 below. The current consumption values when the impregnated bodies were not used are shown as E1.

The fan-type scrubber used in the investigations and tests mentioned above had the fan 41 made as a Silocco fan directly connected to an electric motor 39 (supplied by Mabuchi Motor Co., Ltd. under the product name RF-330TK- 07800) which has a current consumption of 4 mA under no load conditions with an applied voltage of 1.5 volts, the fan also having a fan housing 42 arranged so that it surrounds the fan 41. The housing 45 for housing a mass

or a body impregnated with active component was disposed on the side of the air intake port 43 with respect to the fan 41. For battery 47, two alkaline dry batteries of unit type 3 connected in series are used.

From the results of the investigations and tests mentioned above, it has been determined that if the resistance to wind force R of the mass or the body impregnated with active component 46, specifically the proportion of current consumption of the motor E2 when the mass impregnated with active component 46 is charged with respect to the current consumption E1 when the mass impregnated with active component 46 is not used (R = 100-E2 / E1 x 100) is less than 5% or not less than 26%, no sufficient purification efficiency can be obtained. However, when the proportion is in a range of 5 to 25%, it has been found that sufficient purification efficiency can be obtained.

An engine that drives energy efficiently is allowed to be used to volatilize a large amount of an active component, and volatilization of a maximum amount of the active component and therefore a maximum extent of prevention against insect damage or bugs at a minimum amount of input energy.

A large amount of an active component is volatilized using a mass or a body impregnated with active component having a large effective area and also through the effective use of a created wind.

This is advantageous from the viewpoints of either or both of the retention and release of an active component.

This provides that a prevention effect against the damage of insects or bugs is reliably produced to the maximum extent possible at a minimum of input energy.

Referring to FIG. 5, a fan-type purification apparatus is provided to repel and kill harmful or harmful insects comprising a body part 51 provided with a motor 52, a fan 53 for actuation by the motor 52, a mass or a body impregnated with active component 14 to be ventilated by the fan 53, and a battery 55 that serves as a power source for the motor 52, in which the battery, the motor and the fan constitute a fan-type blower for ventilate the mass or the body impregnated with active component to volatilize an inactive component therein.

The battery 55 can be changed by removing a cover 56.

A fan-type debugging device of this type was implemented using a multi-blade fan for fan 53, a motor having a voltage application of 3.0 volts and a current consumption of 6 milliamps (manufactured by Mabuchi Motor Co ., Ltd. product RF-330TK) for the 52 engine, two dry alkaline batteries of unit 3 type in series for the 55 battery, a particulate cellulose or a mass of cellulose particles for the active component support body or body 54, and teraletrin in an amount of 300 mg for the active component for impregnation in the support mass 54.

For the experimentation, a fan-type purification apparatus thus implemented was placed in an inhabited room (13.2 m2 in size) of straw mat size of 8 and was used every day with an operating time of 12 hours / day

As a result, on day 45 the fan blower no longer worked, which means that it had worked for a real total of 480 hours, and in that period of operation of the fan blower no mosquito bites were detected.

The mass or active component support body should preferably be configured in at least one form selected from the group consisting of a form of granules or particles, a form of lines or strips and a form of chains, filaments or strands that all provide a large effective area It should preferably be composed of at least one material selected from the group consisting of cellulose, polymeric water absorption material, polymeric oil and gel absorption material. Those selections are desired from anyone's point of view.

or both of the retention and release of an active component.

For the active component, preference is given to an insecticide or growth control agent that is not only effective against a harmful or harmful insect but has high safety for men and animals. Such insecticides are preferably pyrethroid insecticides of which teraletrine pralethrin, furamethrin, aletrin and empyntrine are particularly advantageous. Such particular pyrethroid insecticides can be used individually or in combination.

For growth control (inhibition) agents, at least one chemical may be used as preferred which is selected from the group consisting of pyriproxyphene, methoprene and hydroprene.

In addition, the combination of an antioxidant agent and / or an ultraviolet absorption agent in the body impregnated with active component and / or the combination of an ultraviolet absorption agent in a body housing impregnated with active component will allow it to be used. an apparatus stably for a prolonged period of time. It also allows outdoor use.

The end-point marking methods that are essential for the preparation of a chemical include a method of using a lipophilic anthraquinone dye for the body impregnated in case of being hydrophilic and using the phenomena that the color of the dye in If it is dissolved in the chemical it is recognizable and that when the chemical evaporates from the dye it enters the body to make its color unrecognizable. Also included is a method of using a color-changing pigment that is composed of an organic electron-releasing compound that changes color and a desensitizer, or an organic electron-releasing compound that changes color, a desensitizer and a color developer. A method is further included in which the sublimation rate of a sublimation agent is made to be substantially equal to the volatilization rate of the chemical. Although any one of these methods can be used individually, the use of a color change and a sublimation agent in combination will actually make the use felt and will therefore be preferred.

The sublimation rate can be adjusted to a value as required by adjusting the area of a ventilation opening that can be provided for a housing containing the sublimation agent.

Also for the active components described, there is no limitation imposed on the use of the insecticides and / or repellants (insect repellents) listed below, in any combination with a proportion as desired.

For example, to kill insects, any one or more of a variety of volatile insecticides used to date can be used. Illustrative are pyrethroid insecticides, carbamate insecticides and organophosphorus insecticides. Pyrethroid insecticides are known to have high safety and have been used well. Specific examples of pyrethroid insecticides, organophosphorus insecticides, oxadiazole insecticides and chloronicotine insecticides have been listed hereinabove in relation to the first embodiment of the present invention. In addition, specific examples of the growth control agent, specific examples of the repellent and its components, and specific examples of natural volatile oils and their components have been listed hereinbefore.

In addition to an antioxidant agent and an ultraviolet absorbing agent to prevent degradation of the described active component, an inhibitor, depressant and / or retarder can be incorporated to adjust the amount of volatilization of the active component, a substance or substances that have a function or functions to emit fragrance, deodorize and / or sterilize as desired.

For the fan 53 in the fan-type blower, use can be made, if air is to flow from the axial direction to the radial direction, of a centrifugal fan in which a centrifugal force is applied to confer energy to the flow. If air is going to flow in the axial direction, an axial fan can be used in which a vane lifting force is used to confer energy to the flow.

They are illustrative of the centrifugal fan, for example, a turbo fan, a fan of aerodynamic vanes, a fan of limited load, a radial fan, a fan of multiple vanes, and so on.

In this case, centrifugal fans are preferred and a multi-blade fan is more preferred.

It is also preferable that a centrifugal fan is placed as mentioned above in a spiral, conical or spiral casing designed to effectively join winds produced by rotating the fan and then letting them out.

When designing the fan-type blower composed of the fan 53 mounted on the motor 52, it has been found that it is important that it be taken into account as the load acting on the motor 52, the air resistance index f of the fan which is equal to the current consumption of the motor I1 with a motor loaded with the fan divided by the current consumption of the motor I0 with the motor not loaded, and that the relationship is made in this case to be: 1 <f <17, preferably 1 <f <5.

The air resistance index f represents the resistance of the air that a fan blade receives when the fan 53 rotates and is conveniently expressed in this case by the current consumption ratio of the motor 52 when it is charged with the fan 53 with respect to the motor current consumption 52 when not charged.

As the air resistance index f increases, the current consumption of the motor 52 charged with the fan 53 increases. Therefore, it has been found that increasing the air resistance index f up to 18 or more significantly reduces the hours in which the fan 53 can operate without changing the battery.

In addition, the increase in the air resistance index f tends to increase the size of the fan. And, the increase in the air resistance index f up to 18 or more makes the apparatus body 51 excessively bulky and makes it inconvenient for use. For example, the device will become difficult to handle.

The size of the fan 53 should preferably have a diameter of 20 to 100 mm, preferably 30 to 60 mm. With a diameter of 20 mm or less, the fan will have a diameter too small to send air effectively. If it is of the axial type, the fan with a diameter of 20 mm or less will have an area of a vane that is too small to provide sufficient lifting force. In addition, if it is of the centrifugal type, the fan with a diameter of 20 mm or less will have a fan diameter too small for sufficient centrifugal force to be provided.

Attempts to obtain sufficient air flow require that the fan be rotated with an increasing number of rotation. This increases the current consumption of the motor and also requires a higher voltage to be applied. This leads to the increase in the number of batteries for use and makes the device inadequate both in weight and in total cost.

With a diameter of 100 mm or more, the apparatus 51 will become excessively bulky to the extent that it can no longer be a portable or easy to handle debugging apparatus.

The weight of the fan 53 should preferably range between 1.5 and 8 g. Weighing less than 1.5 g, the fan 53 cannot send air in a necessary and sufficient volume.

With a weight greater than 8 g, the fan 53 will become too heavy, causing the inconvenience that too high power is necessary to start the motor 52 and there should be excessive current consumption.

The motor 52 as mentioned above must advantageously be a motor of the energy saving type that has a voltage application of 3 volts and which can be operated with a current consumption of 35 mA or less when it is not charged.

The motor 52 having a current consumption of 36 mA or more when not charged significantly reduces the hours in which the fan-type blower can operate without changing the battery.

For battery 55, one or more commercially available general purpose batteries, such as dry alkaline batteries, dry manganese batteries, etc., may be used. Illustrative for practical applications are a dry manganese battery type unit 3 (with a battery capacity of 1200 mA · h), an alkaline dry battery type unit 3 (with a battery capacity of 2300 mA · h), two dry alkaline batteries of unit type 3 (with a battery capacity of 4600 mA · h), an alkaline dry battery of type 2 (with battery capacity of 6900 mA · h), a dry alkaline battery of unit type 1 (with a battery capacity of 11500 mA · h), two dry alkaline batteries of unit type 2 (with a battery capacity of 13800 mA · h) and two dry alkaline batteries of type unit 1 (with a capacity of the battery of 23000 mA · h).

The battery capacity in this case represents a charge (amount of current) that makes the “battery life” 1 hour with the assumption that the battery life is the time elapsed for the voltage of a 1.5 volt battery (battery or batteries) decrease to 0.9 volts. In other words, the battery capacity means the amount of electrical current that causes a 1.5 volt battery (battery or batteries) to decrease to 0.9 volts in one hour.

Although there are slight differences in indicating the battery capacity, they do not affect the previous example, and the battery capacities shown above are illustrative only.

The previous setting of the air resistance index f of the fan 53, the size of the fan 53, the weight of the fan 53 and the current consumption Io of the motor 52 when not each loaded in the described range provides a debugging apparatus that It is portable or easy to handle. These parameters can be set like this

5 previously in various combinations to give rise to such an apparatus with a varied duration of time in which they can be operated without changing the battery.

Such a duration of time, that is, the hours at which a debugging apparatus as described can be operated without changing the battery can be prolonged by establishing the current consumption of the motor charged with the fan so that the duration ratio of time in which it can be operated with respect to the capacity of the

The battery has a value of not less than 5%, preferably not less than 10%, and more preferably not less than 20%.

For example, if the current consumption of the motor charged with the fan is set to approximately 27.4 mA, the device with a battery capacity of approximately 2300 mA · h can be operated only for a total time duration of approximately 84 hours , making the ratio of the length of time it can be operated with respect to the battery capacity to be approximately 3.7%.

15 However, if the current consumption of the motor charged with the fan is set to approximately 20 mA, the device with the same battery capacity can be operated for a total time duration of 115 hours, thus making the ratio 5%

Assuming that the device is used for 12 hours a day, it can be seen that the former with the 3.7% ratio allows it to be used for 7 days only and the latter with the 5% ratio allows it to be used for 9 days.

20 Mention is made below of specific examples.

With the use of various types of fan and motor in an apparatus as shown in Figure 5, the duration of the apparatus was measured until it became inoperative, however, without using the mass or body impregnated with active component 54. The test results are shown in table 3 below.

Com: comparative test

Current consumption was measured using Kenwood Co., Digital Multimeter DL-712. The measurement was made in a wiring between motor 52 and battery 55.

10 Tests 1 to 7 met the 3 requirements described.

Comparative tests 1 to 6 include those that met only one of the three requirements, those that met two of those requirements, and those that met all of those requirements.

The test results of tests # 1 and 2 are compared with those of comparative test 1. All these tests used the same engine. Comparing test # 1 with comparative test 1, it is observed that among 15 those tests that use the same capacity of the 2300 mAh battery (corresponding to two alkaline batteries of unit 3 connected in series) there is a difference in Fan operating time up to 24 hours. And, if the battery capacity rises up to 23000 mA · h (corresponding to two alkaline batteries of unit 1 type connected in parallel), the difference in fan operating time becomes up to 220 hours, evidencing by Both a significant economic difference. The comparison of test # 1 with the

Comparative test 1 further demonstrates the economic difference between the apparatus of the invention and the prior art.

Comparison of tests 3 and 4 with comparative test 2 has the same or similar results.

Next, the test results of test # 5 are compared with those of comparative test 3. Comparative test 3 used a current consumption of the unloaded motor and an air resistance index of the 25 fan each inside of the corresponding requirement but, having the result of a short duration of

operating time, represents an example that shows that economics cannot be obtained depending on a certain combination of them. Using a battery capacity of 2300 mA · h (corresponding to two alkaline batteries of unit type 3 connected in series), it is observed that test # 5 had a longer operating time of the fan than the comparative test 3 in up to 47 hours. And, if the battery capacity rises up to 23000 mA · h (corresponding to two alkaline batteries of unit 1 type connected in parallel), the difference in the operating time of the fan becomes up to 471 hours.

Comparison of test # 6 with comparative test 4 has the same or similar results.

Next, the test results of test # 3 are compared with those of comparative test 5. These tests used the same fan air resistance index (which does not mean that they used the same fan). Comparative test 5 had a current consumption of the unloaded motor that is outside the required range. The comparison of these tests shows the difference.

It should be noted that comparative test 6 that did not meet any of the requirements evidences how inexpensive the prior art is.

From the previous test results, it will be apparent that satisfying all the requirements provides a long duration of fan operation time.

A fan-type purification apparatus allows a motor and therefore a fan to send air to and to ventilate a mass or a body impregnated with an active component, for a prolonged total number of hours without changing the battery, thereby allowing that the active component is volatilized over a prolonged period of time without requiring a battery change.

A portable or easy-to-handle debugging device is also provided to repel and kill harmful or harmful insects.

An explanation is given below with respect to the apparatus described in the following.

Referring to FIG. 6, an apparatus comprises an apparatus body or body part 51 provided with an electric motor 52, a fan 53, a mass or a body 54 impregnated with an active component and a battery

55. Battery 55 can be replaced by removing a cover 56 from its place.

The motor 52 and the fan 53 constitute a fan-type blower that sends air to and ventilates the mass or the body impregnated with active component 54 to volatilize the active component.

The apparatus body part 51 also incorporates a current control circuit unit 57 such as a timer that controls the power to the motor 52. By manipulating an operating element 58 such as a selector provided therefor, the control circuit unit Power 57 is designed to alternatively turn on and off the exciter current to the motor 52.

For example, the operating element 58 as shown in Figure 7 may have graduations 58a and a knob or button 58b so that the adjustment of the button 58b to a given graduation 58a establishes an on and off time of a particular current according to is desired.

The current control circuit unit 57 can have a pre-set operating period and a stop period therein so that when a power switch is turned on, the motor 52 can be operated during the pre-set operating time period and can be stopped during the period of preset stop time repeating the cycle.

The periods of operating and stopping time have the following relationship.

The stop time period is defined in this case as a period of time that has a duration of no more than 9 (nine) times as long as the operating time period and in which the amount of electric current (amount of electricity) that is not lost is greater than the amount of electric current (amount of electricity) that is consumed when the motor starts to run and that is greater than a stable electric current that appears later.

Mention is made more specifically of the period of downtime.

The electric current rises to a value I1 when the motor starts to run. A stable electric current value less than I2 appears with a certain period of time t0 after the current begins to flow.

The amount of electric current (amount of electricity) S1 that is consumed after starting the motor and within the time t0 until the current becomes stable is greater than the amount of electric current (amount of electricity) S2 that is consumes within the same time period t0 after the current becomes stable. And, there is an excess current consumption (amount of electricity consumed): S1-S2.

If the motor is operated or operated for a period of time t1 and stops for a period of time t2, then the amount of electric current (amount of electricity) S3 not consumed during the period of stop time t2 is expressed by t2 x I2 (magnitude of the stable electric current).

If the amount of electric current (amount of electricity) S3 that is not consumed in the period of downtime t3 is less than the excess current consumption (amount of electricity consumed) S1-S2 that occurs when the motor starts at actuated, then it makes no sense to apply an electric current intermittently because the total current consumption (amount of electricity consumed) when the current is applied intermittently becomes greater than the total current consumption (amount of electricity consumed) when Apply the current continuously. Therefore, the period of stopping time t2 must be a period of time as mentioned above in which the amount of electric current (amount of electricity) S3 not consumed in the period of time t2 is greater than the current consumption in excess (amount of electricity consumed): S1-S2 when the engine starts to run.

A stop time period t2 of this type is expressed by the inequality: t2> (S1-S2) / I2.

The operating time period and the stopping time period can be preset, depending on the purpose, in various ways, for example, in units of days, hours, minutes and seconds. For example, the motor (fan) can be operated or operated periodically for a day and stopped for a day, operated for 1 hour and stopped for 2 hours, operated for 10 minutes and stopped for 50 minutes, and / or operated for 30 seconds and stand for 20 seconds.

A stop time period of any length of time is sufficient unless it is less than 9 times as long as the period of operation or drive time. Naturally, it must be established taking due account of the environmental wealth of the active component in the period of downtime, and a reduction in the environmental wealth of the active component per unit of time.

In addition, the operating time period must be a period of time that is effective and sufficient to exterminate a particular harmful or harmful insect or insects to be exterminated. For example, for female stegomy mosquitoes, it is a period of time required for 50% to be paralyzed or for them to refrain from adopting their hematophagy behavior. For moths, it is a period of time necessary for 50% to be paralyzed or for them to refrain from adopting their food-damaging behavior. The operating time period is determined taking into account a combination of a particular harmful or harmful insect, a particular active component and a particular motor.

For the fan in the fan-type blower for use in the present invention, use, if air is to flow from the axial direction to the radial direction, of a centrifugal fan in which a centrifugal force is applied to confer a flow energy If air is going to flow in the axial direction, an axial fan can be used in which a vane lifting force is used to confer energy to the flow.

They are illustrative of the centrifugal fan, for example, a turbo fan, a fan of aerodynamic vanes, a fan of limited load, a radial fan, a fan of multiple vanes, and so on.

In this case, centrifugal fans are preferred and a multi-blade fan is more preferred.

It is also preferable that a centrifugal fan is placed as mentioned above in a spiral, conical or spiral casing designed to effectively join winds produced by rotating the fan and then letting them out.

In addition, they are illustrative for the battery or battery used to power the fan blower, for example, a primary battery or battery such as an alkaline dry cell, a dry manganese cell, a button cell, a cell battery air or a lithium ion battery, and a secondary battery or battery such as a nickel-cadmium battery or a lithium ion battery.

An appropriate choice of a particular battery or battery may be made together with its class (for example, either alkaline or manganese, or type 1 or unit 2), its number and its connection mode (in parallel or in series) considering its conditions and period of use, the class of the motor and fan used.

The body impregnated with active component should preferably have a conformation or configuration that in addition to a honeycomb form that has an air or gas rectification function is a form of material that has a large effective area that is at least one selected material. from the group consisting of a mass of granules, a mass of strips and a mass of chains, filaments or strands. It is also preferable from the viewpoints of the retention and / or release of the active component that the particulate material that forms the body impregnated with active component is composed of at least one material selected from the group consisting of cellulose, an absorbing agent of polymeric water, a polymeric oil absorption agent and a gel.

The active component is preferably an insecticide or a growth control agent that is effective for one or more kinds of insecticides but that does not harm men or animals.

The insecticides should preferably be pyrethroid insecticides of which at least one chemical selected from the group consisting of teraletrin, pralethrin, furamethrin, aletrin, and emprntrine is particularly advantageous.

For growth control (inhibition) agents, at least one chemical that is selected from the group consisting of pyriproxyphene, methoprene and hydroprene is preferred.

In addition, the combination of an antioxidant agent and / or an ultraviolet absorption agent in the body impregnated with active component and / or the combination of an ultraviolet absorption agent in a body housing impregnated with active component will allow it to be used. a stable implementation over a prolonged period of time. It also allows outdoor use.

The end-point marking methods that are essential for the preparation of a chemical include a method of using a lipophilic anthraquinone dye for the body impregnated in case of being hydrophilic and using the phenomena that the color of the dye in If it is dissolved in the chemical, it is recognizable and that when the chemical evaporates, the dye enters the body to make its color unrecognizable. Also included is a method of using a color-changing pigment that is composed of an organic electron-releasing compound that changes color and a desensitizer, or an organic electron-releasing compound that changes color, a desensitizer and a color developer. A method is further included in which the sublimation rate of a sublimation agent is made to be substantially equal to the volatilization rate of the chemical. Although any one of these methods can be used individually, the use of a color change and a sublimation agent in combination will actually make the use felt and will therefore be preferred.

The sublimation rate can be adjusted to a value as required by adjusting the area of a ventilation opening that can be provided for a housing containing the sublimation agent.

Also for the active components described, listed below there is no limitation imposed on the use of insecticides and / or repellants (insect repellents), in any combination with a proportion as desired.

For example, to kill insects, any one or more of a variety of volatile insecticides used to date can be used. Illustrative are pyrethroid insecticides, carbamate insecticides and organophosphorus insecticides. Pyrethroid insecticides are known to have high safety and have been used well. Specific examples of pyrethroid insecticides, organophosphorus insecticides, oxadiazole insecticides and chloronicotine insecticides have been listed hereinabove in relation to the first embodiment of the present invention. In addition, specific examples of the growth control agent, specific examples of the repellent and its components, and specific examples of natural volatile oils and their components have been listed hereinbefore.

In addition to an antioxidant agent and an ultraviolet absorbing agent to prevent degradation of the described active component, an inhibitor, depressant and / or retarder can be incorporated to adjust the amount of volatilization of the active component, a substance or substances having the function or functions of emitting a fragrance, deodorant and / or sterilizer.

Mentioned below are the tests and their results.

Using a fan-type purification apparatus as shown in Figure 6, tests were carried out regarding hematophagy by female stegomy mosquitoes.

The engine used in the fan-type scrubber was an RF-330TK model engine manufactured by Mabuchi Motor Co., Ltd.

The battery consisted of two alkaline batteries of unit 3 type connected in series.

The chemical used was teraletrin and the support or impregnable body was a mass of granules or particles composed of a cellulose.

The conditions of the tests were as follows:

•

The tests were carried out in inhabited rooms (7.4, 13.2, 16.5 and 19.8 m2) with straw mats of 4, 5, 8, 10 and 12.

•

One of the four walls of each room had a ventilation window of 1 m x 1 m in size that was left open at all times.

•

A substantially constant room temperature of 25 ° C was maintained.

•

The period of each of the tests was half a year (180 days).

Tests 1 to 3 were longer in days of use than comparative test 1 in which it is applied so

10 continuous electric current, but they were able to achieve an efficiency equivalent to that achieved by comparative test 1. Test # 1 allowed the days of use to be three times more than in the case of continuous use but had an efficiency substantially equal to which could be achieved through the latter. Test # 2 allowed the days of use to be six times longer than in the case of continuous use and did not have hemophagia although it observed some decrease in efficacy towards the end of the days. Test # 3 did not achieve an eminent cessation,

15 but it was effective enough to prevent hematophagy and allowed the days of use to be 10 times longer than in the case of continuous use.

Comparative test 3 was sufficient in terms of efficacy, but it was short in terms of days of use despite the fact that the current was turned on and off, obviously not being able to meet the requirement: t2> (S1-S2) / I2 .

Therefore, it has been shown that a fan-type purification apparatus if used in an inhabited space achieves sufficient efficiency and maintains it for a prolonged period of time.

It will be appreciated that any apparatus as described hereinbefore may be individually applied in a combination to the first embodiment of the described invention.

An explanation is given below.

In order to solve the problem (1) mentioned hereinbefore in the explanation of the prior art, a support body or impregnated with chemical (a support body or impregnated with active component) is made to be granular or particulate, that is, it is made in the form of a mass of particles or granules, and these granules or support particles or impregnated with chemical are stirred. It has been found that this makes the amounts of air or wind flows received by the supports uniform, thus preventing the amount of the chemical remaining in the body or particulate mass impregnated with chemical product from varying depending on a local site in the air flow direction. The effects have been demonstrated from the tests carried out whose methods and test results are explained below.

A test apparatus was made by placing it in a square wind blow outlet with 8 cm side in an impregnated body receptacle composed of a cylinder with 8 cm internal diameter and 10 cm high and with nets placed to cover its upper part and lower. The receptacle housed in it a mass of 2 grams of weight of granules having a diameter of 4 mm and impregnated with a chemical of 300 milligrams in weight. The local variations in the amount of the chemical that remained in that mass were measured after an operation of three (3) full days (24 hours).

As a comparison, the local variation of the chemical that remained in a monolithic non-mobile body in the form of a honeycomb impregnated with the chemical placed in the same square wind blow outlet of 8 cm side was also measured. The test results are shown in table 8 below.

Table 8

The numerical values in the table indicate the quantities that remain for 100 of the chemical load. Each measurement site is indicated by the distance from the body's blowout outlet or mass impregnated with chemical.

In Table 8, the numerical values each indicate a quantity that remains for 100 of the chemical load. Each measurement site is indicated by the distance from the blow outlet of the monolithic body or granular mass impregnated with chemical.

When a monolithic body impregnated with chemical is used, it is observed that a chemical tends to volatilize more in places closer to the blower outlet of the fan, and very little in places away from it in which it tends to stay 90% or more of the chemical. On the contrary, if you make use of a particle or granular mass impregnated with the chemical, it is shown that there is substantially no difference in the amount remaining between locally different sites by virtue of the fact that the particulate mass

or granular impregnated with the chemical while stirring constantly acts to volatilize the chemical.

In addition, in order to solve the problem (2) mentioned above in the prior art explanation, a measure has been taken as mentioned below. Therefore, the body impregnated with chemical is made to have a mass of particles or granules whose number is increased in a given space. This makes each individual chemical carrier granule or particle smaller and in turn makes the travel distance of the chemical shorter. As a result, the chemical as it volatilizes from the external surfaces of the particulate mass impregnated with chemical is recharged more quickly from the interior to those external surfaces, thereby causing the density or concentration of the chemical in the Dough be uniform throughout its volume. This establishes a stabilized volatilization state of the chemical. In addition, it is also conceivable to add any of several

classes of solvents as a measure to promote uniformity in the distribution of the chemical in each granule or particle carrying individual chemical. It is found that this is an effective measure for a chemical that has high viscosity and low mobility.

Tests were also carried out to investigate volatilization patterns of a chemical from a particulate mass impregnated with chemical and a monolithic body impregnated with chemical in the prior art. Each of these chemical supports had an identical amount and type of chemical impregnated therein and was operated for fifteen (15) consecutive days. On each of the fifth, tenth and fifteenth days a measurement of the amount of chemical remaining is made, from which the amount of volatilization of the chemical per unit of time is estimated. The test results are shown in table 9 below and also in the graph of figure 9.

From the test results shown in Table 9 above and the graph of Figure 9, it is observed that in the monolithic body the volatilization rate is substantially reduced proportionally from the start of operation while in the particulate mass the Amount of volatilization is stable. It is thought that this stabilized amount of volatilization over a prolonged period of time is attributable to the fact that the agitation or beating of the chemical carrier particles used to form the chemical impregnated mass makes the concentration of the chemical uniform by full volume and causes the chemical to flow or move dynamically in each individual carrier particle. It is also thought to be attributable to the fact that a reduction in weight as a result of the volatilization of the chemical causes the specific weight of each of the dough and the impregnated chemical to be reduced, which in turn increases the mobility of chemical carrier particles; As a result, the increased mobility still maintains the amount of volatilization of the chemical substantially at a given level although the concentration of the chemical is reduced.

In addition, as regards the effective volatilization rate, which is the proportion of the amount of chemical that is its initial charge amount minus the amount left on the 15th day with respect to its initial charge amount shown in Table 9, notes that the value of 89.46% in the case of the particulate mass compared to the value of 72.58 in the case of the monolithic body indicates that the particulate mass allows highly effective volatilization of the chemical.

In addition, in order to solve the problem (3) mentioned above in this document in the explanation of the prior art, a measure has been taken as mentioned below. Therefore, the efficient use of energy is achieved by having the chemical-bearing particles such as the mass impregnated with chemical receive both types of wind, that is, winds from the fan and winds created when they themselves are rotated. This makes the total required surface area of the mass as a whole smaller than that of a conventional body, and reduces the loss of a wind force. Table 10 shows the test results using a particulate mass impregnated with chemical and a monolithic body impregnated with honeycomb-shaped chemical in the prior art in which both the particulate mass and the monolithic body had an identical real volume. , and a wind force was measured at each of the sites 5 cm above and 10 cm above, respectively, of the volatilization output of chemical. In this case again, the test results show that the particulate porous mass is more favorable than the monolithic porous body, demonstrating that the former produces a higher wind speed and produces a lower loss of wind strength, than the latter.

The tests and test results have also shown the following: thus, in order to maintain the amount of volatilization of a chemical for a prolonged period of time preventing the local volatilization variation in the particulate mass impregnated with chemical while using effectively the energy of the wind force of the fan, it is desirable that the chemical-bearing particles that form the particulate mass be beaten or shaken in a moderate manner or to an appropriate extent. For this purpose, it has been found that certain requirements must be met as mentioned below.

First, there is a requirement that refers to the configuration of the chemical carrier particles. It is desirable that the chemical-bearing particles have a shape that minimizes their resistance or braking by mutual friction that leads to a loss of energy when agitated, that is, a particle shape such that the maximum contact area of a particle with another does not exceed one half of its total surface area. Specifically, it is desirable that the chemical-bearing particles each have the shape of a sphere that will be the shape that provides minimal friction.

A second requirement for chemical carrier particles requires that particles as a particulate mass have an appropriate set of capabilities for the chemical, that is, the ability to charge (impregnate) with the chemical, the ability to discharge (release ) the chemical, and the ability to promote that the chemical rapidly becomes uniform in the particulate mass. The ability to load with chemical depends on the actual volume of the particulate mass, and the ability to discharge the chemical and the ability to promote the chemical to become uniform rapidly depend on the density and therefore the porosity of the particulate mass .

The actual volume of a particulate mass that is required for this aspect can be derived from its porosity and apparent volume, and can be adjusted as desired in a range as mentioned below with the properties of the chemical such as its pressure of vapor and viscosity that are taken into account. The actual volume of a chemical-containing particulate mass, expressed by [apparent volume x (1 porosity / 100)], should desirably oscillate, for each particle, between 5 x 10-5 and 5 x 105 mm3, preferably between 5 x 10-3 and 5 x 103 mm3, more preferably between 5 x 10-2 and 5 x 10-1 mm3. And, the amount of volatilization and the number of days in which efficacy on which the efficacy will last can be adjusted by the number of the particles carrying the chemical and the concentration of the chemical to be carried in this way.

A third requirement for the particulate mass impregnated with or carrying a chemical requires that it have a specific weight in a range between 0.005 and 0.5 when the air flow per unit of time of the wind passing through a receptacle that houses the chemical-containing particulate mass ranges between 0.01 and 1.0 m3 / min. However, if a large fan is used that has an air flow of 1.0 m3 / min. or more, the chemical-bearing particulate mass can be used even if it has a specific gravity of 0.5 or more.

A fourth requirement may also be included that requires that either or both of the chemical-bearing particulate mass or its receptacle be processed for an antistatic. There is a possibility that an electrostatic agent, if developed, can act to prevent agitation between the chemical carrier particles or between the chemical carrier particles and their receptacles.

In view of the foregoing, a chemical volatilization product is provided, in which a mass of particles or a particulate material is housed in a receptacle and is impregnated therein with a chemical to serve as a support for it, the carrier particles are ventilated with winds from a fan and, while stirring or beating by wind forces, allowing the chemical impregnated in the particulate mass to volatilize.

A chemical volatilization apparatus as described is also characterized in that each of the chemical-bearing particles should preferably have a shape such that the maximum area of contact of one particle with another is not greater than half the area of total surface area of the particle.

A chemical volatilization apparatus as described is also characterized in that the actual volume of a particulate mass carrying a chemical, expressed by [apparent volume x (1 porosity / 100)], should desirably oscillate, for each particle, between 5 x 10-5 and 5 x 105 mm3, preferably between 5 x 10-3 and 5 x 103 mm3, more preferably between 5 x 10-2 and 5 x 10-1 mm3.

A chemical volatilization apparatus as described is also characterized in that the particulate mass impregnated with or carrying a chemical product should preferably have a specific weight in a range between 0.005 and 0.5 when the air flow per unit time of the Wind passes through a receptacle that houses the chemical-carrying particulate mass between 0.01 and 1.0 m3 / min.

A chemical volatilization method as described is further characterized in that either or both of the chemical-containing particulate mass for volatilization of chemicals

or its receptacle should preferably be preprocessed for an antistatic.

A chemical for use in the present invention as impregnated in the chemical-containing particulate mass may be any of known volatile chemicals and should be selected according to their intended use thereof.

For example, to kill insects, any one or more of a variety of volatile insecticides used to date can be used. Illustrative are pyrethroid insecticides, carbamate insecticides and organophosphorus insecticides.

Next, mention is made of materials that can be used for the impregnable particles or impregnated mass or chemical support. They are illustrative, for example, viscose, borra and inorganic substances such as calcium silicate. Alternatives can be porous bodies formed as row materials, synthetic fibers such as polypropylene and can also be activated carbon. Among them, the most preferred is a material of plant origin such as paste, viscose or erasure as a raw material for the particulate material or the impregnable particle or chemical support in view of its specific weight and ability to carry the chemical. Such commercially available materials include foamed cellulose pearls that are composed of pulp and viscose as the main raw materials and are supplied by Rengo, K. K. under the trade name Viscopar (spelled phonetically).

The promotion of agitation of the chemical-impregnated carrier particles mentioned above requires that they be light, having a lower specific weight. Its receptacle is preferably composed of plastic that is electrically non-conductive, light and also economical in nature. However, friction or rubbing contact plastic tends to carry electrostatic charges and once charged it is difficult to release them. Therefore, it is possible that the carrier particles of the chemical are of lower specific weight, when they are beaten to prevent agitation and therefore that it becomes detrimental to energy efficiency. Therefore, it is desirable to apply an antistatic treatment to the particles carrying the chemical and preferably also to its receptacle. A typical broad plastic antistatic treatment method is by means of an additive and a surfactant is used for this purpose. In such methods, an antistatic agent can be coated on the surfaces of a plastic (surface coating method) or alternatively mixed in a plastic body (mixing method). Such agents are anionic, cationic, non-ionic or bipolar ionic active agents suitably adapted to the methods. A variety of chemicals that have a surfactant as its main component is commercially available. Examples are "Sanstat AA", "Sanstat 2012A" and "Sanstat 249" manufactured by Sanyo Chemical Industries Ltd., and "Colcoat SP-2001" and "Colcoat SP-2002" that offer transparency as a non-conductive coating "manufactured Colcoat, K. K (all written phonetically).

It is also possible to use one or more of an antioxidant agent, an ultraviolet absorbing agent, an aromatic product, a deodorant, etc., to add an efficiency that increases stability, synergistic efficacy and other attractive properties.

When it is desired to volatilize a chemical that is less volatile efficiently, a method that is designed to promote volatilization by heating the carrier of the carrier particles, the fan itself or any peripheral element is conceivable.

Example 1

On the side with respect to the square blow outlet of the 8 cm side of an axial brushless DC motor manufactured by KK Siko Giken, a chemical was placed containing a cylindrical cartridge of 18 cm internal diameter and 10 cm of high with its bottom and top covered with nets. The cartridge housed in it a mass of 2 grams of weight of particles of 2 mm in diameter consisting of foamed cellulose beads, impregnated with 300 milligrams of praletrin. The device in operation was switched on and off in a cyclic manner with a 12-hour on-time and a 12-hour off time and the cycle repeated 30 times. Changes over time in the amount of volatilization of the chemical were measured and plotted in the graph shown in Figure 10. The stopping power against common domestic mosquitoes was also measured and shown in Table 4. It should be indicated. in this case, the amount of volatilization is indicated by a value per unit of time (hour) calculated from the chemical residue that was extracted from the particulate mass impregnated with chemical and was measured in a given time interval. The power or efficiency is represented by the results of tests carried out in a closed space of size (13.2 m2) of straw mat of 8 at a constant temperature of 25 ° C.

The apparatus used in this example had a fan motor mounted therein and a construction in which, as shown in Figure 11, a body part 61 had a blow outlet (not indicated in the figure) opened by the upper part in which a receptacle housing particulate mass 63 with its upper and lower part covered with networks 62a and 62b was mounted. In operation, as the fan is rotated, winds are blown upwards from the network 62b of the bottom of the receptacle 63 to fluidize the particulate mass, indicated by the differentiated particles 64, housed therein and allow at the same time that the chemical impregnated in the dough volatilizes and then diffuses through the upper network 62a to the outside along with the winds.

Example 2

Using the same apparatus, a test was carried out in which the particulate mass was again a mass of 2 grams of foamed cellulose beads of 2 mm in diameter which in this example was impregnated with 1200 milligrams of aletrin. Under the same test conditions as in Example 1, changes in the volume of volatilization of the chemical and the stopping power for common domestic mosquitoes were measured. The test results are shown in Figure 10 and Table 11.

Example 3

Using the same apparatus, a test was carried out in which the particulate mass was a mass of 2 grams of foamed cellulose beads 4 mm in diameter, which in this example was impregnated with 1000 milligrams of teraletrine. Under the same test conditions as in Example 1, changes in the volume of volatilization of the chemical and the stopping power for common domestic mosquitoes were measured. The test results are shown in Figure 10 and Table 11.

Example 4

Using the same apparatus, a test was carried out in which the particulate mass was a mass of 2 grams of foamed cellulose beads of 4 mm in diameter, which in this example was impregnated with 2000 milligrams of empentrin. Under the same test conditions as in Example 1, changes in the volume of volatilization of the chemical and the stopping power for common domestic mosquitoes were measured. The test results are shown in Figure 10 and Table 11.
