Abstract

Disclosed is an insecticidal device whereby injuries and diseases caused by insect pests and diseases caused by bacteria, viruses and so on can be prevented at the same time. An insecticidal device (1) comprising a mosquito coil (M) that is held in a housing (14). After lighting the mosquito coil (M), an insecticidal component emitted therefrom diffuses outside through an outlet (412), together with air introduced from an air inlet (411) in the first air passage (41), due to the draft effect. Also, positive and negative ions generated from an ion generator (21) are emitted outside through an outlet (412) by an air blower (22). Thus, mosquitoes can be killed and influenza viruses can be inactivated. Since a solar battery (31) is used to supply electricity for driving the ion generator (21) and the air blower (22), a user can carry the insecticidal device (1).

Description

Insecticidal equipment

The present invention relates to an insecticidal device for distributing insecticidal components in the air.

2. Description of the Related Art Conventionally, insecticidal devices have been proposed that exterminate pests by distributing insecticidal components (for example, pyrethrin) (see Patent Documents 1 and 2).
The portable electric mosquito catcher described in Patent Document 1 distributes a vaporized insecticidal component by heating a liquid insecticide. The portable mosquito trap described in Patent Document 2 distributes the vaporized insecticidal component by burning a solid insecticide.

In addition, portable mosquito coils have been used for a long time to use mosquito coils, which are smoke-type insecticides, outdoors.
A portable mosquito coil is attached to, for example, each metal dish container and the lid of the dish container, a non-combustible heat insulating material (eg, a glass mat) laid inside the dish container, and the back of the lid. A wire mesh. A plurality of openings are formed in the lid, and the ignited mosquito coil is sandwiched between a wire mesh and a heat insulating material. The dish-shaped container is provided with a metal fitting for the user to suspend the portable mosquito coil from the waist.
The insecticidal component of the mosquito coil is distributed around the user carrying the portable mosquito coil by passing through the wire net and the opening of the lid together with the smoke generated by the incompletely burning mosquito coil.

The portable insecticidal device as described above is widely used for prevention of insect bites and pest-borne infectious diseases (for example, dengue fever transmitted by mosquitoes as a medium in the Southeast Asian region).

By the way, conventionally, an air purifier or an air conditioner that discharges ions generated by an ion generator into the air has been used.
The ions generated by the ion generator can kill or inactivate fungi (for example, molds) and viruses (for example, influenza viruses) floating in the air.

JP 2001-103898 A Japanese Patent Laid-Open No. 3-56379

However, the insecticidal component distributed by the insecticidal device cannot kill or inactivate fungi and viruses. For example, mosquito coils have no effect on various influenza viruses that cause bird flu and swine flu, which have recently been feared for pandemics.
On the other hand, ion generators cannot get rid of pests.

The present invention has been made in view of such circumstances, and the main purpose of the present invention is to prevent wounds and diseases caused by pests, fungi, viruses, etc. by disposing both insecticide components and ions in the air. An object of the present invention is to provide an insecticidal device capable of simultaneously preventing a disease caused by the disease.

The insecticidal apparatus according to the present invention is an insecticidal apparatus for killing insects by distributing insecticidal components in the air, comprising an ion generator, and releasing ions generated by the ion generator into the air. It is characterized by.

An insecticidal apparatus according to the present invention includes an air passage having openings at both ends, an accommodating portion that contains an insecticide that releases an insecticidal component by being burned or heated, and communicates with the air passage. The ion generator is characterized in that ions are generated inside the air passage or in a space communicating with the air passage.

The insecticidal apparatus according to the present invention is further characterized by further comprising a blower for blowing air to release at least the ions generated by the ion generator.

The insecticidal apparatus according to the present invention further includes at least a power supply unit that supplies power to the ion generator.

The insecticidal apparatus according to the present invention is characterized in that the power supply unit uses a solar cell.

The insecticidal apparatus according to the present invention is characterized in that the ion generator generates positive ions and negative ions.

In the present invention, the insecticidal apparatus includes an ion generator.
The insecticidal device contains, for example, a solid or liquid insecticide, and distributes a gaseous insecticidal component released from the contained insecticide into the air. Alternatively, the insecticidal device contains a gaseous insecticidal component and distributes the contained insecticidal component in the air.
Further, the insecticidal device releases ions generated by the ion generator into the air. Electric power for generating ions is supplied from, for example, a commercial power source.

In the present invention, the insecticidal device further includes an air passage and an accommodating portion.
The storage unit stores an insecticide. Insecticides release vaporized insecticidal components by burning themselves. Or an insecticide releases the vaporized insecticide component by being heated. Thus, the air containing the insecticidal component released from the insecticide has a higher temperature and a lower density than the air around the insecticidal device, for example.
The air passage has openings at both ends. The ventilation path is preferably provided in the vertical direction. Hereinafter, the opening arranged on the upper side (or the lower side) is referred to as the upper side opening (or the lower side opening).

Since the housing portion communicates with the air passage, the insecticidal component released from the insecticide flows into the air passage. Then, convection due to the draft effect (chimney effect) occurs inside the air passage. More specifically, high-temperature, low-density light air containing an insecticidal component flows out to the outside through the upper opening of the ventilation path, and low-temperature, high-density heavy air flows from the outside through the lower opening of the ventilation path. As a result, the insecticidal component can be distributed efficiently.
If the ventilation path is provided in the horizontal direction, or if the ventilation path is open only on the upper side or the lower side, convection due to the draft effect is unlikely to occur, so that the efficiency of spreading the insecticidal component decreases.

The ion generator generates ions inside the air passage or in a space communicating with the air passage. For this reason, the produced | generated ion flows out outside with the air containing an insecticidal component through the upper side opening of a ventilation path. That is, ions can be efficiently released using convection due to the draft effect.
Therefore, it is not necessary for the insecticidal apparatus to include a blower for forcibly releasing the insecticidal components and ions. As a result, a small and lightweight insecticidal device can be manufactured at a low cost by the amount not equipped with a blower. Moreover, it can contribute to energy saving as much as the blower does not consume electric power, and can reduce the running cost of the insecticidal device.

In the present invention, the insecticidal apparatus further includes a blower.
When the blower blows, at least ions generated by the ion generator are forcibly released. For this reason, for example, ions can be released more efficiently than when ions are released using convection by the draft effect.
In addition, the structure which utilizes the wind which the air blower generate | occur | produced for the forced distribution of an insecticidal component may be sufficient as an insecticidal apparatus. In this case, both the insecticidal component and the ions can be efficiently diffused.

In the present invention, the insecticidal apparatus further includes a power supply unit.
The power supply unit supplies power to at least the ion generator. Therefore, since the insecticidal apparatus does not need to receive power from, for example, a commercial power source in order to generate ions, the insecticidal apparatus can be used at an arbitrary place. In particular, when the power supply unit is configured using a primary battery and / or a secondary battery, a portable insecticidal device can be obtained.
In addition, when an insecticidal apparatus is provided with electric equipments, such as an electric blower or an electric heater, it is desirable for a power supply part to supply electric power to both an ion generator and an electric equipment.

In this invention, an insecticidal apparatus is further provided with the power supply part which uses a solar cell.
Portable insecticidal devices are often used outdoors. For this reason, the electric power obtained by photoelectrically converting abundant sunlight can be supplied to at least the ion generator.
As a result, the consumption of the primary battery or the secondary battery can be reduced. Or the electric power which should charge a secondary battery can be covered with the electric power which the solar cell generated. Accordingly, it is possible to contribute to energy saving and to reduce the running cost of the insecticidal device.

In the present invention, the ion generator generates positive ions and negative ions. For this reason, both positive ions and negative ions are released into the air.
When both positive ions and negative ions are released, the effect of killing or inactivating fungi and viruses is more significant than when either positive ions or negative ions are released. As a result, it is possible to simultaneously and more reliably suppress the occurrence of wounds and diseases caused by pests and the occurrence of diseases caused by fungi or viruses.

In the case of the insecticidal device of the present invention, both the insecticidal components and ions can be diffused into the air. For this reason, pests can be exterminated and fungi and viruses can be inactivated or killed. As a result, it is possible to simultaneously suppress the occurrence of wounds and diseases caused by pests and the occurrence of diseases caused by fungi or viruses.
Moreover, when using the insecticidal apparatus of this invention, it is not necessary to use together an insecticidal apparatus, an air cleaner provided with an ion generator, or an air conditioner. That is, the pesticide device of the present invention is more practical than conventional insecticide devices that have only insecticidal ability.

Hereinafter, the present invention will be described in detail based on the drawings showing the embodiments thereof.

Embodiment 1.
1 and 2 are a front perspective view and a rear perspective view schematically showing an appearance of the insecticidal apparatus 1 according to Embodiment 1 of the present invention.
The insecticidal device 1 includes a lid 11, a device main body 12, and a hanging tool 13. The apparatus main body 12 includes a first container 121 and a second container 122. The lid 11, the first container 121, and the second container 122 are made of an insulating synthetic resin.

The suspending tool 13 is a synthetic resin or metal member having a distal end portion formed in a bowl shape, and a proximal end portion is fixed to the apparatus main body 12.
The user suspends the insecticidal apparatus 1 from the waist, for example, by locking the suspending tool 13 to the belt of the pants he or she is wearing.
Hereinafter, the side on which the hanging tool 13 of the insecticidal apparatus 1 is fixed is referred to as the upper side of the insecticidal apparatus 1.

3 and 4 are front views schematically showing the internal configurations of the first container 121 and the second container 122 provided in the insecticidal apparatus 1.
FIG. 5 is a longitudinal sectional view schematically showing the internal configuration of the insecticidal apparatus 1.
As shown in FIG. 3, the mosquito coil M is a solid insecticide formed in a spiral flat plate shape, and emits smoke and a pyrethroid insecticide component by burning. The insecticidal apparatus 1 can kill mosquitoes by spreading the insecticidal component contained in the mosquito coil M in the air.

As shown in FIGS. 1, 2, and 5, the lid 11 has a bottomed cylindrical shape. The front part 111 of the lid 11 corresponds to the bottom part of the bottomed cylinder.
As shown in FIGS. 1 to 5, the first container 121 (and the second container 122) of the apparatus main body 12 has a bottomed cylindrical shape. The back surface portion of the first container 121 (and the second container 122) corresponds to the bottom surface portion of the bottomed cylinder.

A solar cell 31 having a power generation surface on the front surface is embedded on the front surface side of the front portion 111 of the lid 11.
On the back side of the front portion 111 of the lid 11, a heat insulating material 141 made of glass wool is projected. The heat insulating material 141 is not limited to glass wool, but is required to have a material or a structure that is nonflammable, hardly transmits heat, and does not inhibit the burning of the mosquito coil M.

The lid 11 functions as a lid for the apparatus main body 12. More specifically, the lid 11 is configured to open and close the front opening of the first container 121. For this purpose, the peripheral surface portion 112 of the lid 11 is detachably fitted to the peripheral surface portion of the first container 121. If the user removes the lid 11 from the first container 121, the front opening of the first container 121 is opened, and if the user attaches the lid 11 to the first container 121, the front opening of the first container 121 is closed. Is done.

An air inlet 411 and an air outlet 412 of the first air passage 41 to be described later are formed at positions that are not closed by the peripheral surface portion 112 of the lid 11 at the upper peripheral surface and the lower peripheral surface of the first container 121, respectively.
When the lid 11 closes the front opening of the first container 121, the first air passage 41 is formed inside the first container 121. More specifically, the first air passage 41 is a space surrounded by the lid 11 and the bottom surface portion and the peripheral surface portion of the first container 121, and is external to the insecticidal apparatus 1 through the intake port 411 and the exhaust port 412. Communicating with That is, the intake port 411 and the exhaust port 412 are open at both ends of the first air passage 41.

The inside of the 1st container 121 is the accommodating part 14 which accommodates the mosquito coil M. More specifically, the accommodating portion 14 is a space surrounded by at least the bottom surface portion and the peripheral surface portion of the first container 121.
In other words, the accommodating portion 14 serves as the first air passage 41 and communicates with the first air passage 41. For this reason, it is not necessary to separately provide a communication path for communicating the accommodating portion 14 and the first ventilation path 41. Therefore, the insecticidal apparatus 1 is compact.

A heat insulating material 142 similar to the heat insulating material 141 is disposed on the bottom surface of the housing portion 14 from the center in the vertical direction (arrow A1 direction) to the lower portion. Each of the

heat insulating materials

141 and 142 has a reverse Y-shape when viewed from the front (see FIG. 3). In addition, the structure which covers the back surface side of the front part 111 of the lid | cover 11 and the bottom face part of the accommodating part 14 entirely may be sufficient as the heat insulating material 141 and the heat insulating material 142.

When the lid 11 closes the front opening of the first container 121, the heat insulating material 141 and the heat insulating material 142 are opposed to each other in the front-rear direction (arrow A2 direction).
When the user removes the lid 11 from the first container 121, the mosquito coil M is placed on the heat insulating material 142, and then the lid 11 is attached from the first container 121, so that the mosquito coil M is insulated from the heat insulating material 141. , 142.

An exhaust port 422 of a second air passage 42 to be described later is formed in the upper part of the bottom surface of the housing part 14.
Since the housing part 14 also serves as the first air passage 41, when the mosquito coil M stored in the housing part 14 burns, the smoke and the insecticidal component are released to the first air passage 41. At this time, convection due to the draft effect occurs in the first air passage 41 (see the arrow in FIG. 5). More specifically, the air inside the first air passage 41 heated by the burning mosquito coil M and the released smoke and insecticidal components are discharged to the outside of the insecticidal apparatus 1 through the exhaust port 412. At this time, air is sucked into the first air passage 41 from the outside of the insecticidal device 1 through the air inlet 411.

The first container 121 opens and closes the front opening of the second container 122. For this purpose, the first container 121 and the second container 122 are provided with a plurality of sets of locking tools (not shown). When the user unlocks the locking members and then removes the first container 121 from the second container 122, the front opening of the second container 122 is opened, and the user removes the first container 121. If it attaches to the 2nd container 122 and then it makes a locking tool latch, the front opening of the 2nd container 122 will be closed.

An air inlet 421 of the second air passage 42 is formed at the lower back of the second container 122.

Partition walls

423 and 424 project from the back surface portion of the second container 122 along the vertical direction, and the positions of the tip portions of the

partition walls

423 and 424 are the same as the position of the tip portion of the peripheral surface portion of the second container 122. It is almost the same. The

partition walls

423 and 424 divide the inside of the second container 122 into three in the left-right direction.

The partition wall 425 faces the bottom surface of the second container 122 and is disposed from the upper part of the second container 122 to the central part in the vertical direction. The upper end portion of the partition wall 425 is fixed to the upper part of the peripheral surface of the second container 122, the lower end portion of the partition wall 425 is fixed to the center in the vertical direction of the bottom surface portion of the second container 122, In contact with the

partition walls

423 and 424. The partition wall 425 divides the upper side inside the second container 122 into two in the front-rear direction. An opening 426 is formed in the partition wall 425.

A storage battery 32 is mounted in a space surrounded by the peripheral surface portion and the bottom surface portion of the second container 122 and the partition wall 423. In addition, the dry battery 33 is detachably mounted in a space surrounded by the peripheral surface portion and the bottom surface portion of the second container 122 and the partition wall 424.
The ion generator 21 is disposed in a space surrounded by the peripheral surface portion and the bottom surface portion of the second container 122, the

partition walls

423 and 424, and the back surface side of the partition wall 425. The opening 426 of the partition wall 425 is closed by the casing of the ion generator 21.

When the first container 121 closes the front opening of the second container 122, the front ends of the

partition walls

423 and 424 come into contact with the bottom surface of the first container 121. At this time, the second ventilation path 42 is formed inside the second container 122. More specifically, the second ventilation path 42 is a space surrounded by the bottom surface portion of the first container 121, the peripheral surface portion and the bottom surface portion of the second container 122, the

partition walls

423 and 424, and the front surface side of the partition wall 425. It is. The second air passage 42 communicates with the outside of the insecticidal apparatus 1 through the air inlet 421, and communicates with the first air passage 41 through the air outlet 422.

The blower 22 is disposed inside the second air passage 42. The blower 22 includes an electric motor 221 and a fan 222, and the fan 222 is disposed to face the air inlet 421.

The user opens and closes the first container 121 with the lid 11 when the mosquito coil M is stored in the storage unit 14 or when the ash of the mosquito coil M remaining in the storage unit 14 is removed.
The user opens and closes the second container 122 by the first container 121 when the dry battery 33 is attached to the second container 122 or when the attached dry battery 33 is replaced with a new dry battery 33. .
The storage battery 32 may be detachably attached to the second container 122. In this case, the user may charge the storage battery 32 with an external charger.

FIG. 6 is a block diagram showing a main configuration of the insecticidal apparatus 1.
The insecticidal device 1 includes a power supply unit 3, and the power supply unit 3 includes a switch 30, a solar battery 31, a storage battery 32, and a dry battery 33.
The solar cell 31 has a photoelectric conversion element on the power generation surface, and generates power by photoelectrically converting light incident on the power generation surface. The electric power generated by the solar battery 31 is given to the storage battery 32.
The storage battery 32 is a secondary battery and is charged by being fed from the solar battery 31. The dry battery 33 is a primary battery.

Each of the storage battery 32 and the dry battery 33 is electrically connected to the ion generator 21 and the blower 22 via the switch 30. Therefore, if the switch 30 is in the ON state, the power output from each of the storage battery 32 and the dry battery 33 is given to the ion generator 21 and the blower 22.
Note that the insecticidal device 1 may be configured to include two storage batteries that are each charged by being fed from the solar battery 31. Further, the insecticidal device 1 may have a configuration in which the solar battery 31 is directly connected to the switch 30 without including the storage battery 32 and the dry battery 33.

The solar cell 31 is disposed on the lid 11, and the storage battery 32 is disposed on the second container 122. For this reason, the lid 11 is provided with a first connection cable 351 directly connected to the solar cell 31, and the second container 122 is provided with a second connection cable 352 directly connected to the storage battery 32. The container 121 is provided with a third connection cable 353 for electrically connecting the first connection cable 351 and the second connection cable 352.

When the lid 11 is attached to the first container 121, the connection terminal provided at the tip of the first connection cable 351 and the connection terminal provided at one end of the third connection cable 353 are, for example, permanent magnets. It is electrically connected by the adsorption force. Similarly, when the first container 121 is attached to the second container 122, a connection terminal provided at the tip of the second connection cable 352 and a connection terminal provided at the other end of the third connection cable 353; Are electrically connected.
When the lid 11 is removed from the first container 121 or when the first container 121 is removed from the second container 122, the electrical connection between the solar cell 31 and the storage battery 32 is broken.

Direct current is supplied from each of the storage battery 32 and the dry battery 33. For this reason, the electric motor 221 of the blower 22 uses a DC motor. When the electric motor 221 using an AC motor is provided, the blower 22 needs to include an inverter that converts direct current into alternating current between the switch 30 and the electric motor 221.
The electric motor 221 continues to operate while being supplied with power from the power supply unit 3. At this time, the fan 222 rotates and air is sucked into the second air passage 42 from the outside of the insecticidal device 1 through the air inlet 421 as indicated by white arrows in FIG. The sucked air passes through the second ventilation path 42 from the lower side to the upper side, and is discharged to the first ventilation path 41 through the exhaust port 422. The discharged air is discharged to the outside of the insecticidal apparatus 1 through the exhaust port 412 together with the air inside the first air passage 41.

In the vicinity of the exhaust port 422, an inclined surface for guiding the air discharged from the second air passage 42 to the exhaust port 412 side is formed (for example, an inclined surface on the upper part of the partition wall 425). For this reason, the air exhausted from the second ventilation path 42 to the first ventilation path 41 through the exhaust port 422 is prevented from flowing back through the first ventilation path 41 from the upper side to the lower side. Therefore, the convection caused by the combustion of the mosquito coil M is suppressed from being inhibited by the air discharged from the exhaust port 422.

On the other hand, the air discharged from the exhaust port 422 moves upward together with the air inside the first air passage 41, thereby promoting the flow of air from the lower side to the upper side inside the first air passage 41. There is. Therefore, it is possible to prevent the combustion of the mosquito coil incense M from being excessively promoted by appropriately setting the air flow rate of the blower 22 at the design stage. As a result, the inconvenience that the forced air blowing by the blower 22 shortens the combustion time of the mosquito coil M is suppressed.

The ion generator 21 generates both positive ions H ⁺ (H ₂ O) _n (n is an arbitrary integer) and negative ions O ₂ ⁻ (H ₂ O) _m (m is an arbitrary integer). It is configured to generate. For this purpose, the ion generator 21 includes an electrode unit 211 and an AC high voltage generation unit 212. Hereinafter, positive ions and negative ions are referred to as positive and negative ions.
The AC high voltage generator 212 includes an inverter that converts direct current fed from the storage battery 32 and the dry battery 33 to alternating current, and a transformer that boosts the alternating voltage. The AC high voltage generated by the AC high voltage generation unit 212 is applied to the electrode unit 211.

The electrode part 211 is formed by using a pair of electrodes arranged to face each other with a dielectric interposed therebetween. The electrode part 211 to which the alternating high voltage is applied generates positive and negative ions by corona discharge.
Further, the electrode portion 211 is exposed to the second ventilation path 42 through the opening 426. For this reason, positive and negative ions generated by the electrode portion 211 are released to the second ventilation path 42. In other words, the ion generator 21 generates ions in a space communicating with the first air passage 41.
The released positive and negative ions are discharged to the outside of the insecticidal apparatus 1 together with the air passing through the second air passage 42.

The configuration of the electrode unit 211 may be the same as the configuration of the electrode unit included in the conventional corona discharge ion generator. However, in this case, the AC high voltage generator 212 needs to have a configuration that can convert the DC low voltage of the storage battery 32 and the dry battery 33 into an AC high voltage that generates corona discharge. The ion generator 21 is not limited to the corona discharge type.

The insecticidal device 1 as described above uses an insecticidal component included in the mosquito coil M and positive and negative ions generated by the ion generator 21 by using both convection by the draft effect and blowing by the blower 22. Can be efficiently released into the air.
For this reason, the insecticidal apparatus 1 can get rid of mosquitoes and reliably inactivate, for example, influenza viruses. As a result, the dengue epidemic and the influenza epidemic can be suppressed simultaneously.

Moreover, the insecticidal apparatus 1 is portable, and besides the insecticidal apparatus 1, it is not necessary to use other electrical equipment including an ion generator. That is, the insecticidal apparatus 1 is highly practical.
In addition, since the power generated by the solar cell 31 can be used, the insecticidal apparatus 1 can contribute to energy saving and the running cost is low.
Furthermore, when the release of positive and negative ions is unnecessary, the consumption of the storage battery 32 and the dry battery 33 can be suppressed by turning off the switch 30.

The lid 11 may be made of metal. In this case, an insulating member is interposed between the solar battery 31 and the solar battery 31 in order to prevent electric leakage from the solar battery 31.
The lid 11, the first container 121, and the second container 122 may be made of metal. In this case, an insulating coating is formed on the surface of at least the portion of the lid 11, the first container 121, and the second container 122 through which positive and negative ions pass. This is because the metal exposed on the surface may inhibit the release of positive and negative ions.

By the way, as shown in FIG. 5, the base end portion of the hanging tool 13 is fixed to the outside of the back surface portion of the second container 122. For this reason, when the user locks the suspending tool 13 on his / her clothing, the first ventilation path 41 is arranged in a substantially vertical direction, so that convection due to the draft effect is likely to occur. However, the air inlet 421 may be blocked by the user's body.
Therefore, the insecticidal apparatus 1 may be configured to fix the base end portion of the hanging tool 13 to the upper peripheral surface of the second container 122. In this case, when the user locks the suspending tool 13 on his / her clothing, the insecticidal device 1 can be inclined, and a sufficient gap can be provided between the air inlet 421 and the user's body. However, since the 1st ventilation path 41 is arranged in the inclination attitude | position, there exists a possibility that the convection by a draft effect may be inhibited.

Note that the insecticidal apparatus 1 may be configured as a stationary insecticidal apparatus. In this case, the insecticidal apparatus 1 may be configured to be supplied with driving power from a commercial power source.
Further, for example, the solar battery 31 may be provided in a power supply device that is separate from the main body of the insecticidal device 1, and the power supply device may supply power to the insecticidal device 1.

Furthermore, the ion generator 21 may be configured to be switchable between a case where positive and negative ions are generated and a case where mainly negative ions are generated. When negative ions are mainly generated, the effect of killing or inactivating fungi and viruses is inferior to that when positive and negative ions are generated, but the relaxation effect is improved. In this case, positive and negative ions are generated when the insecticidal apparatus 1 is used outdoors, and negative ions are mainly generated when used indoors.

Furthermore, the insecticidal apparatus 1 may include a control circuit that controls the amount of positive and negative ions generated in the ion generator 21 and / or the amount of air blown in the blower 22. Further, it may be possible to change the blowing direction of the blower 22 by providing a movable louver in the vicinity of the exhaust port 422 and controlling the inclination angle of the movable louver.

Embodiment 2. FIG.
FIG. 7 is a block diagram showing a main configuration of the insecticidal apparatus 1 according to Embodiment 2 of the present invention. FIG. 7 corresponds to FIG. 6 of the first embodiment.
The insecticidal apparatus 1 according to the present embodiment has substantially the same configuration as the insecticidal apparatus 1 according to the first embodiment. However, the insecticidal apparatus 1 of the present embodiment does not include the solar cell 31. Therefore, the insecticidal apparatus 1 does not include the first connection cable 351 to the third connection cable 353.

In the space surrounded by the peripheral surface portion and the bottom surface portion of the second container 122 and the partition wall 423 as shown in FIG. 4, not the storage battery 32 but a dry battery 34 is detachably mounted.
Each of the

dry batteries

33 and 34 is electrically connected to the ion generator 21 and the blower 22 via the switch 30. Therefore, if the switch 30 is in the ON state, the power output from each of the

dry batteries

33 and 34 is given to the ion generator 21 and the blower 22.
Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The insecticidal apparatus 1 as described above has substantially the same effect as the insecticidal apparatus 1 of the first embodiment. Moreover, since it is not necessary to use the power generated by the solar cell 31, the insecticidal apparatus 1 can be used without problems even in places where the amount of light is small, such as at night, outdoors during cloudy weather, or indoors.
The insecticidal apparatus 1 according to the present embodiment may have a configuration in which the base end portion of the hanging tool 13 is fixed to the outside of the front portion of the lid 11. In this case, there is no possibility that the air inlet 421 is blocked by the user's body, and there is no possibility that the convection due to the draft effect is hindered by arranging the first air passage 41 in the inclined posture.

Embodiment 3. FIG.
FIG. 8 is a longitudinal sectional view schematically showing the internal configuration of the insecticidal apparatus 1 according to the third embodiment of the present invention, and corresponds to FIG. 5 of the first embodiment.
FIG. 9 is a block diagram showing a main configuration of the insecticidal apparatus 1 and corresponds to FIG. 6 of the first embodiment.

The insecticidal apparatus 1 according to the present embodiment has substantially the same configuration as the insecticidal apparatus 1 according to the first embodiment. However, although the insecticidal apparatus 1 of the first embodiment includes the second container 122 that incorporates the blower 22, the insecticidal apparatus 1 of the present embodiment does not include the blower 22. It has.
The second container 123 corresponds to the second container 122 of Embodiment 1, but does not include the partition walls 423 to 425. Further, the second ventilation path 42 is not formed inside the second container 123. For this reason, the depth (dimension in the front-rear direction) of the second container 123 is shallower than the depth of the second container 122 of the first embodiment. Further, the intake port 421, the exhaust port 422, and the opening 426 are not formed.

As shown in FIG. 8, an opening 413 is formed in the upper part of the bottom surface of the accommodating portion 14. When the first container 121 closes the front opening of the second container 123, the opening 413 is closed by the casing of the ion generator 21, and the electrode part 211 is exposed to the first air passage 41 through the opening 413. For this reason, positive and negative ions generated by the electrode portion 211 are released to the first air passage 41. In other words, the ion generator 21 generates ions inside the first air passage 41.

As shown in FIG. 9, each of the storage battery 32 and the dry battery 33 is electrically connected to the ion generator 21 via the switch 30. Therefore, if the switch 30 is in the ON state, the power output from each of the storage battery 32 and the dry battery 33 is supplied to the ion generator 21.
Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

The insecticidal apparatus 1 as described above efficiently releases the insecticidal components contained in the mosquito coil M and the positive and negative ions generated by the ion generator 21 into the air using convection due to the draft effect. The effects similar to those of the insecticidal apparatus 1 of the first embodiment can be obtained.
In addition, the insecticidal apparatus 1 is small and light, and is inexpensive because the blower 22 and the second air passage 42 are not provided. Moreover, since it is not necessary to supply electric power to the blower 22, it can contribute to energy saving and the running cost of the insecticidal apparatus 1 can be reduced.

Embodiment 4 FIG.
FIG. 10 is a longitudinal sectional view schematically showing the internal configuration of the insecticidal apparatus 1 according to the fourth embodiment of the present invention, and corresponds to FIG. 5 of the first embodiment.
Unlike the insecticidal apparatus 1 of the first to third embodiments, the insecticidal apparatus 1 of the present embodiment has a configuration in which an ion generator 21 and a blower 22 are provided on the back of a conventional portable mosquito coil. However, the principal part structure of the insecticidal apparatus 1 of this Embodiment is the same as that of the principal part structure shown by FIG. That is, the insecticidal apparatus 1 does not include the solar battery 31, and the ion generator 21 and the blower 22 are supplied with driving power from the two

dry batteries

33 and 34.

The insecticidal device 1 includes a lid 15, a device body 16, and a hanging tool 13. The apparatus main body 16 includes a first container 161 and a second container 162. The lid 15 is made of metal and corresponds to the lid 11 of the first embodiment. Each of the first container 161 and the second container 162 is made of an insulating synthetic resin, and corresponds to the first container 121 and the second container 122 of the first embodiment. The first container 161 may be made of metal, but in this case, an insulating film is formed on the outer side of the back surface of the first container 161.

The inside of the first container 161 is a housing portion 14 that houses the mosquito coil M. A heat insulating material 142 is disposed on the bottom surface of the housing portion 14.
The lid 15 functions as a lid for the apparatus main body 16. More specifically, the lid 15 is configured to open and close the front opening of the first container 161.

A plurality of

openings

151, 151,... Are formed in the front portion of the lid 15. On the back side of the front portion of the lid 15, a clamping member 143 using a wire mesh is disposed. When the lid 15 closes the front opening of the first container 161, the holding member 143 and the heat insulating material 142 hold the mosquito coil M.
The pinching member 143 is nonflammable, does not inhibit the burning of the mosquito coil M, and smoke and insecticidal components emitted from the mosquito coil M are easily moved from the inside of the housing portion 14 to the

openings

151, 151,. As long as it is a possible material or structure, it is not limited to a wire mesh.

When the mosquito coil M stored in the storage unit 14 burns, the smoke and the insecticidal component are discharged to the outside of the insecticidal apparatus 1 through the

openings

151, 151,. At this time, air is sucked into the accommodating portion 14 from the outside of the insecticidal apparatus 1 through the

openings

151, 151,.

The partition walls 443 and 443 (only one partition wall 443 is shown in FIG. 10) project from the back surface of the second container 122 along the vertical direction. The

partition walls

443 and 443 correspond to the

partition walls

423 and 424 of Embodiment 1. An opening 444 is formed in one partition wall 443.

A dry battery 34 is mounted in a space surrounded by the peripheral surface portion and the bottom surface portion of the second container 162 and one partition wall 443, and the ion generator 21 is disposed. The opening 444 of the partition wall 443 is closed by the casing of the ion generator 21.
A dry battery 33 is detachably mounted in a space surrounded by the peripheral surface portion and bottom surface portion of the second container 162 and the other partition wall 443.

The first container 161 opens and closes the front opening of the second container 162.
When the first container 161 closes the front opening of the second container 162, an air passage 44 is formed inside the second container 162. More specifically, the air passage 44 is a space surrounded by the bottom surface portion of the first container 161, the peripheral surface portion and the bottom surface portion of the second container 162, and the

partition walls

443 and 443.

The air passage 44 communicates with the outside of the insecticidal apparatus 1 through the intake port 441 and the exhaust port 442, respectively. The intake port 441 and the exhaust port 442 are formed in the upper peripheral surface and the lower peripheral surface of the second container 162. That is, the intake port 441 and the exhaust port 442 are open at both ends of the air passage 44.
Inside the air passage 44, the blower 22 is disposed so that the fan 222 faces the air inlet 441.

The electric motor 221 continues to operate while being supplied with power from the power supply unit 3. At this time, the fan 222 rotates and air is sucked into the air passage 44 from the outside of the insecticidal apparatus 1 through the air inlet 441 as indicated by white arrows in FIG. The sucked air passes through the ventilation path 44 from the lower side to the upper side, and is discharged to the outside of the insecticidal apparatus 1 through the exhaust port 442.

The electrode portion 211 of the ion generator 21 is exposed to the ventilation path 44 through the opening 444. For this reason, positive and negative ions generated by the electrode portion 211 are released to the ventilation path 44. In other words, the ion generator 21 generates ions inside the air passage 44.
The released positive and negative ions are discharged to the outside of the insecticidal apparatus 1 together with the air passing through the air passage 44.
Other parts corresponding to those of the first and second embodiments are denoted by the same reference numerals, and description thereof is omitted.

The insecticidal apparatus 1 as described above has substantially the same effect as the insecticidal apparatus 1 of the first embodiment. Moreover, since it is not necessary to use the power generated by the solar cell 31, the insecticidal apparatus 1 can be used without any problem even in a place where the amount of light is small.
By the way, the base end portion of the hanging tool 13 is fixed to the outside of the back surface portion of the second container 162. For this reason, when the user locks the hanging tool 13 on his / her clothing, there is no possibility that the intake port 441 and the exhaust port 442 are blocked by the user's body.

Furthermore, if the 2nd container 162 is removed, the insecticidal apparatus 1 can be used similarly to the conventional installation-type mosquito coil.
Furthermore, even if the second container 162 is still attached, the insecticidal device 1 can be used in the same manner as an installation type mosquito coil incense dish if the switch 30 is turned off. At this time, since the suspending tool 13 abuts against the floor surface, the insecticidal apparatus 1 is inclined, but it can be used without any problem as in the case where the conventional installation-type mosquito coils are inclined. This is because there is no long ventilation path like the first ventilation path 41 of the first embodiment between the accommodating portion 14 and the outside of the insecticidal apparatus 1.

By the way, the insecticide apparatus 1 of Embodiment 1 may be configured to include the first container 161 and the second container 162 of this embodiment instead of the first container 121 and the second container 122. In this case, there is no inconvenience that the air inlet 421 is blocked by the user's body.

However, in this case, the intake direction at the intake port 441 and the intake direction at the intake port 411 are the same. For this reason, there is a possibility that a large amount of air flows into the first air passage 41 through the air inlet 411 due to the air blown by the blower 22. Therefore, the burning of the mosquito coil M is excessively promoted, and the burning time of the mosquito coil M may be shortened.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is not intended to include the above-described meanings, but is intended to include meanings equivalent to the claims and all modifications within the scope of the claims.
For example, the insecticidal apparatus 1 is not limited to the structure which burns the solid mosquito coil M. The insecticidal apparatus 1 may be configured to use an insecticide effective against pests other than mosquitoes, or may be configured to heat a liquid insecticide.
In addition, as long as the effect of the present invention is obtained, the insecticidal apparatus 1 may include components that are not disclosed in the first to fourth embodiments.
