Description

The present invention relates to a sprayer that sprays mist, and is particularly suitable for use in a sprayer of a type that introduces air, sucks up a spray liquid, turns it into a mist, and sprays it.

In recent years, sprayers (so-called diffusers) that mist a spray liquid having an aromatic component such as aroma oil and spray it as a mist have become widespread. As for the atomizer, not only the stationary type but also the portable type is becoming widespread. The mobile type simply means that it is small enough to be carried and can be used in the space brought in. The mobile atomizer is used, for example, by being brought into the vehicle.

There are various methods for the sprayer to spray the mist. For example, there are a method of generating and spraying mist by vibrating a liquid by ultrasonic waves, and a method of generating and spraying mist by a mist nozzle having fine spray holes formed therein. In addition, as a method of spraying mist by a sprayer, a method of introducing air, sucking up the spray liquid by the Venturi effect, turning it into mist and spraying it (hereinafter, referred to as "correspondence method") is known (for example, Patent Document 1). reference).

The sprayer described in Patent Document 1 includes a storage tank, an inner pipe, an outer pipe, a lid portion, and a separation plate (upper separation plate). The atomizer described in Patent Document 1 introduces compressed air into the air supply passage of the inner pipe by an air pump, so that the spray liquid stored in the storage tank is introduced into a liquid flow path formed between the inner pipe and the outer pipe. Mist is generated in the space between the tip of the inner pipe and the tip of the outer pipe by the compressed air that is sucked up through and ejected from the air supply port of the inner pipe, and the generated mist is separated from the mist outlet of the outer pipe. Spray towards the board. Then, the sprayer described in Patent Document 1 separates coarse mist and fine mist by a separation plate, and sprays only the fine mist to the outside of the main body through the mist discharge hole of the lid portion. In a sprayer that sprays mist by a corresponding method like the sprayer described in Patent Document 1, it is necessary to secure a space between the tip of the inner pipe and the tip of the outer pipe, so that the spray is stored in a storage tank. It is necessary that the liquid level of the spray liquid to be sprayed is located below the tip (air supply port) of the inner pipe.

Patent No. 5991685

Here, it is considered that the mobile sprayer is composed of a sprayer of a type that sprays mist by a corresponding method. The mobile sprayer prevents the work of supplying the spray liquid from occurring frequently at the destination of the sprayer, so that the mist is continuously sprayed for as long as possible without the work of supplying the spray liquid. Time is required. In particular, when the sprayer is brought into the vehicle and used, the driver cannot replenish the spray liquid to the sprayer while driving the vehicle, so that the period during which the mist is continuously sprayed is lengthened. , It is strongly required to prevent the shortage of spray liquid from occurring during the operation. Furthermore, the mobile sprayer can as much as possible the air volume and pressure of the wind output by the air pump required for driving (hereinafter, the combination of the air volume and the wind pressure of the wind output by the air pump is referred to as "output air volume" for convenience). It is required to be small. This is because if it is possible to drive with a small output air volume, a small output air pump can be used, and the power saving and miniaturization of the atomizer can be realized. It should be noted that the mobile sprayer is usually equipped with a battery instead of a commercial power source and receives power from the battery, or is supplied with power from an external battery at the place where it is brought in, so that it saves power. There is a strong demand for conversion.

In a sprayer of the type that sprays mist by the corresponding method, if the length of the inner pipe and the outer pipe is shortened, the length of the liquid flow path formed between the outer circumference of the inner pipe and the inner circumference of the outer pipe is shortened. Therefore, the output air volume of the air pump can be reduced, the power saving of the atomizer, and the miniaturization of the atomizer due to the miniaturization of the air pump can be realized. However, as described above, in the type of sprayer that sprays mist by the corresponding method, the liquid level of the spray liquid stored in the storage tank needs to be located below the tip of the inner pipe (air supply port). Therefore, the shorter the length of the inner pipe and the outer pipe, the smaller the maximum amount of the spray liquid that can be stored in the storage tank, and the longer the mist spraying period is hindered. On the contrary, if the length of the inner pipe and the outer pipe is increased and the maximum amount of the spray liquid that can be stored in the storage tank is increased for the purpose of prolonging the mist spraying period, the decrease in the output air volume of the air pump is hindered. I will end up.

The present invention has been made to solve such a problem. For a sprayer of a type in which air is introduced to suck up a spray liquid, and the spray liquid is made into a mist and sprayed, the mist spraying period is lengthened and the mist is sprayed. The purpose is to simultaneously reduce the output air volume of the air pump.

In order to solve the above-mentioned problems, the sprayer of the present invention closes the housing, the storage tank chamber in which the storage tank which is formed in the housing and can store the spray liquid is formed, and the upper opening of the storage tank chamber. A lid with a mist discharge hole, an inner pipe provided in the storage tank chamber with an air supply port for discharging air at the tip, an air pump for supplying air to the inner pipe, and a liquid flow path for the inner pipe. An outer tube that is externally inserted with a gap to form a mist spout at the tip and a liquid suction port at the base end, and between the lid and the outer tube. A spray unit having a separation plate provided at a position facing the mist spout, a storage chamber formed in a housing and a space for storing a container for storing the spray liquid, and a storage chamber. A liquid supply unit provided below the chamber and having a temporary storage unit for temporarily storing the spray liquid supplied from the container while supplying the spray liquid from the container stored in the storage chamber, and provided in the housing. It is equipped with an introduction route for introducing the spray liquid stored in the temporary storage unit into the storage tank room, and depending on the supply of the spray liquid from the container to the temporary storage unit, the spray liquid is supplied from the temporary storage unit to the temporary storage unit via the introduction route. The spray liquid is introduced into the storage tank chamber, and the liquid level of the spray liquid stored in the temporary storage section and the liquid level of the spray liquid stored in the storage tank chamber rise integrally at the same position. Regardless of the remaining amount of the spray liquid stored in the storage tank chamber, when the position of the liquid level of the spray liquid stored in the storage tank chamber is lower than the predetermined position, the supply of the spray liquid from the container is stopped and the liquid level is raised. It is configured to stop rising. Further, a plurality of combinations of a spray unit and a liquid supply unit connected by an introduction path are provided in the housing.

According to the present invention configured as described above, a liquid supply unit is provided separately from the spray unit, and the spray liquid is supplied from the container stored in the storage chamber of the liquid supply unit to the storage tank of the spray unit. Therefore, the maximum amount of the spray liquid that can be stored in the container becomes the maximum amount of the spray liquid that can be used by the spray unit, and the mist spray period can be extended. On top of that, in a type of atomizer that sprays mist by introducing air, sucking up the spray liquid, turning it into mist, and spraying it, the liquid level of the spray liquid in the storage tank is always located below the tip of the inner pipe. However, according to the present invention configured as described above, the position of the spray liquid level in the storage tank does not exceed the predetermined position regardless of the remaining amount of the spray liquid remaining in the container. , The lengths of the inner and outer pipes may be set so that the height of the tip of the inner pipe exceeds a predetermined position upward, and the lengths of the inner and outer pipes can be shortened. And by shortening the length of the outer pipe, it is possible to reduce the output air volume of the air pump.

FIG. 5 is a diagram showing a state of the spray liquid when the rise of the liquid level is stopped. It is a figure which shows an example of a drink holder. It is a top view of the atomizer which concerns on a modification.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 (A) is a top view of the atomizer 1 according to the present embodiment, FIG. 1 (B) is a front view of the atomizer 1, and FIG. 1 (C) is a bottom view of the atomizer 1. FIG. 1D is a right side view of the atomizer 1. Hereinafter, as shown by the arrows in FIG. 1 (B), when the atomizer 1 is placed on a horizontal table, the upward direction in the vertical direction is referred to as "upward", and the downward direction is referred to as "downward". That is.

The sprayer 1 is a device that atomizes and sprays the spray liquid. In particular, the sprayer 1 according to the present embodiment can store three types of spray liquids, and can selectively spray mist based on one or more spray liquids. Further, the atomizer 1 according to the present embodiment is a mobile atomizer, and the user can bring the atomizer 1 into a predetermined space and use it. The mobile type simply means that it is small enough to be carried and can be used in the space brought in, and the usage mode may be any. For example, the atomizer 1 may be fixedly attached to the space brought in and used.

As shown in FIG. 1, the atomizer 1 has a housing 2. The housing 2 has a bottom surface 3 in the lower end region, a bottomed tubular case member 5 having an upper end opening 4 formed in the upper end region, and an installation base 6 provided inside the case member 5. .. As shown in FIG. 1, the outer peripheral shape of the bottom surface 3 (FIG. 1 (C)) of the housing 2 is a circle. Further, the outer peripheral shape of the upper end opening 4 (FIG. 1 (A)) of the housing 2 has three sides H (side HA, side HB and side HC) and three connection portions T (connection portion TA, connection portion TB). And a shape having a connecting portion TC) (hereinafter, referred to as a “number-corresponding shape”). As shown in FIG. 1 (A), the lengths of the three sides H are the same, the shapes of the three connecting portions T are arcuate, and the shape corresponding to the number is an equilateral triangle in which the connecting portions T are arcuate. It has a similar shape.

As shown in FIG. 1, the three-dimensional shape of the housing 2 is such that the outer peripheral shape of the cross section gradually changes from a circle to a number-corresponding shape from the bottom surface 3 toward the upper end opening 4. FIG. 2 is a diagram showing the outer peripheral shape of the bottom surface 3 and the outer peripheral shape of the upper end opening 4 together with the outer peripheral shape of the AA cross section of FIG. 1 (B) in order to explain the three-dimensional shape of the housing 2. .. In FIG. 2, (A) shows the outer peripheral shape of the upper end opening 4, (B) shows the outer peripheral shape of the AA cross section of FIG. 1 (B), and (C) shows the outer peripheral shape of the bottom surface 3. Since the three-dimensional shape of the housing 2 gradually changes from a circle to a number-corresponding shape from the bottom surface 3 toward the upper end opening 4, the outer peripheral shape of the cross section of the housing 2 is downward. The cross section located is closer to a circle, and the cross section located upward is closer to the number-corresponding shape. Further, as shown in FIG. 2, the circumscribed circle of each cross section of the housing 2 gradually increases from the bottom surface 3 toward the upper end opening 4.

As shown in FIG. 1 (C), the horizontal positions of the center of the circumscribed circle of the number-corresponding shape related to the upper end region of the housing 2 and the center of the circle related to the lower end region coincide with each other at the position P1. .. Therefore, despite the shape in which the three-dimensional shape of the housing 2 expands upward, when the housing 2 is placed on a horizontal surface, it is difficult for an unbalanced force to overturn the housing 2 to work, and the housing 2 is hard to work. The body 2 can be stably placed on a horizontal plane. In the present embodiment, since the lengths of the three sides H of the number-corresponding shape related to the upper end region of the housing 2 are the same, a simple solid is compared with the case where the lengths of the three sides H are different. Depending on the shape, the center of the circumscribed circle of the number-corresponding shape related to the upper end region of the housing 2 and the center of the circle related to the lower end region can be aligned in the horizontal direction. Further, as described above, since the shape of each of the three connecting portions T is arcuate, the housing 2 is directed from the bottom surface 3 toward the upper end opening 4 as compared with the case where the three connecting portions T have sharp angles. The shape of the shape changes smoothly, and the design is high. The diameter of the bottom surface 3 of the housing 2 is about 70 mm, the diameter of the circumscribed circle of the upper end opening 4 of the housing is about 90 mm, the height of the housing 2 is about 160 mm, and the atomizer 1 has a sprayer 1. It is large enough for an adult to hold with one hand.

As shown in FIG. 1B, the case member 5 is divided into a lower case 8 located below and an upper case 9 located above the central portion in the vertical direction as a boundary.

Further, the panel 13 is provided with a timer switch 15 for setting the time length for driving the atomizer 1. In the present embodiment, the user can switch the driving time of the atomizer 1 to any of 5 minutes / 10 minutes / 15 minutes by operating the timer switch 15. Further, the panel 13 stores a container 17 (see FIG. 5) used for spraying mist among the three storage chambers 16 (first storage chamber 16A, second storage chamber 16B, and third storage chamber 16C). A container selection switch 23 for selecting the storage chamber is provided. The container 17 is a container in which the spray liquid is stored, and as will be described in detail later, the sprayer 1 has a maximum of three containers in the first storage chamber 16A, the second storage chamber 16B, and the third storage chamber 16C. 17 can be stored. By operating the container selection switch 23, the user can use any one of the first storage chamber 16A, the second storage chamber 16B, and the third storage chamber 16C, or any two storage chambers 16. All three storage chambers 16 can be selected.

As shown in FIGS. 1A and 1B, the upper case 9 is provided with an installation base 6. The installation table 6 has three spray units 10 (first spray unit 10A, second spray unit 10B and third spray unit 10C), and three liquid supply units 18 (first liquid supply unit 18A, second liquid supply). The stand on which the unit 18B and the third liquid supply unit 18C) are installed. As shown in FIG. 1A, the upper surface 6a of the installation table 6 is located below the upper end opening 4 of the housing 2, and the upper surface 6a of the installation table 6 and the upper end opening 4 of the housing 2 An upper space 19 is formed between the spaces, which is a space surrounded by a case member 5.

As shown in FIGS. 1 (A) and 1 (B), the installation table 6 has three spray unit 10 storage tank chambers 20 (first storage tank chamber 20A, second storage tank chamber 20B and third storage tank chamber 20C), and The storage chambers 16 (first storage chamber 16A, second storage chamber 16B, and third storage chamber 16C) of the three liquid supply units 18 are bored. More specifically, the three storage chambers 20 and the three storage chambers 16 each have a columnar space extending downward from the upper surface 6a of the installation table 6, and the storage tank chamber 20 The storage chamber 16 and the storage chamber 16 are provided in the installation table 6 as holes (recesses) in which the upper end region is opened, respectively. FIG. 1B schematically shows the position of the first storage tank chamber 20A of the first spray unit 10A and the position of the first storage chamber 16A of the first liquid supply unit 18A when the sprayer 1 is viewed from the front. ing. In the installation table 6, the position where the storage tank chamber 20 is provided is the position of the spray unit 10, and the position where the storage chamber 16 is provided is the position of the liquid supply unit 18.

As described above, the outer peripheral shape of the upper end opening 4 (upper end region) of the housing 2 has three sides H (side HA, side HB and side HC) having the same length and three arc-shaped connecting portions T (connections). It is a number-corresponding shape having a portion TA, a connecting portion TB, and a connecting portion TC). As shown in FIG. 1 (A), in the installation table 6, the three spray units 10 are arranged at positions corresponding to the three connection portions T, respectively. More specifically, the three spray units 10 are arranged in the vicinity of each of the three connecting portions T in a state of being separated by the same angle (120 °) on the virtual circle KS1. Due to such a configuration, each of the three spray units 10 can be efficiently separated from the installation table 6.

Further, the sprayer 1 according to the present embodiment can spray three types of mist, but the outer peripheral shape of the upper end region is a number-corresponding shape having the same number of connection portions T as the number of types of mist that can be sprayed. Therefore, at the upper end portion of the housing 2, the number of portions (connecting portions T) protruding outward and the number of types of mist that can be sprayed match. As a result, the appearance of the atomizer 1 can be related to the number of types of mist that can be sprayed, and the appearance of the atomizer 1 can be made to take advantage of the feature that three types of mist can be sprayed. Can be done. As a result, the user can intuitively recognize the type and number of mists that can be sprayed only by looking at the appearance of the sprayer 1, which is highly convenient for the user. In particular, in the sprayer 1 according to the present embodiment, since each spray unit 10 is provided in the vicinity of each connection portion T, the user can simply look at the appearance of the sprayer 1 and the position where the mist is sprayed on the sprayer 1. Can be intuitively recognized. The user can change the direction of the atomizer 1 based on the recognition, which is also highly convenient for the user.

As described above, each of the three spray units 10 is arranged at a position corresponding to each of the three connecting portions T (near each of the three connecting portions T). Therefore, in the installation table 6, the spray unit 10 of 1 and the other spray unit 10 are separated from each other with a certain space. On top of that, as shown in FIG. 1A, in the installation table 6, one liquid supply unit 18 is arranged in the space between the spray unit 10 and the spray unit 10. Due to this configuration, one of the three liquid supply units 18 is arranged in the space that is inevitably created when each of the three spray units 10 is arranged at a position corresponding to each of the three connection portions T. The liquid supply unit 18 is efficiently arranged by effectively utilizing the dead space, and the increase in size of the housing 2 is suppressed.

Then, as shown in FIG. 1A, the pair of spray units 10 and the liquid supply unit 18 are provided on the installation table 6 in an adjacent state. Therefore, as compared with the case where the pair of spray units 10 and the liquid supply unit 18 are arranged apart from each other on the installation table 6, the installation table 6 can be miniaturized, and the sprayer 1 can be miniaturized. Further, since the pair of spray units 10 and the liquid supply unit 18 are provided on the installation table 6 in a state of being adjacent to each other, and the non-paired spray units 10 and the liquid supply unit 18 are arranged apart from each other, the user can use the user. When looking at the upper surface of the housing 2, the combination of the pair of spray units 10 and the liquid supply unit 18 corresponding to each other can be intuitively recognized. As will be described later, the user can store the container 17 in the storage chamber 16 of the liquid supply unit 18, but due to the above configuration, when the container 17 is stored in the storage chamber 16, the pair of spray units 10 and the liquid are stored. The container 17 can be stored in an appropriate storage chamber 16 after accurately recognizing the combination with the supply unit 18.

Further, the storage tank chamber side connection portion 52, which is a connection portion between the introduction path 21 and the storage tank chamber 20, is located above the liquid suction port 54 (described later) of the outer pipe 53 provided in the storage tank chamber 20. ..

Under the above configuration, when the container 17 is stored in the storage chamber 16 (when the container 17 is attached to the holding mechanism 48), the spray liquid stored in the container 17 is supplied to the storage tank chamber 20 in the following manner. .. That is, when the container 17 in which the spray liquid is sufficiently stored is attached to the holding mechanism 48 by screwing in an upside-down state, the spray liquid to be stored in the container 17 is temporarily stored little by little through the liquid supply port 45 of the pipe 44. It is supplied to the unit 46. As described above, since the storage chamber side connection portion 51 is located at the lower end portion of the temporary storage portion 46, the spray liquid supplied to the temporary storage portion 46 initially passes through the introduction path 21. , Introduced into the storage tank room 20 and stored in the storage tank room 20. Further, in the container 17, a closed space 55 (see FIG. 6) is formed above the liquid level of the spray liquid remaining in the container 17.

As the supply of the spray liquid from the container 17 to the temporary storage unit 46 progresses, the water level of the spray liquid stored in the storage tank chamber 20 gradually rises, and the liquid level in the storage tank chamber 20 faces upward on the bottom surface of the temporary storage unit 46. It will be in a state of exceeding. After this state, since the temporary storage section 46 and the storage tank chamber 20 are connected via the introduction path 21, the height of the liquid level in the storage tank chamber 20 and the height of the liquid level in the temporary storage section 46 Are in agreement, and according to the supply of the liquid from the container 17, these liquid levels rise integrally while maintaining the state where the heights of these liquid levels are the same. As the liquid level in the temporary storage unit 46 rises, the liquid supply port 45 of the pipe 44 of the container 17 is immersed in the spray liquid stored in the temporary storage unit 46. If the liquid level continues to rise in response to the supply of the spray liquid from the container 17, the rise of the liquid level stops at a certain position.

FIG. 6 is a diagram schematically showing a state of the spray liquid when the rise of the liquid level is stopped in FIG. As described above, the internal space of the temporary storage portion 46 is a space open to atmospheric pressure, and the storage tank chamber 20 is also a space communicating with the mist discharge hole 26 formed in the lid portion 24, and thus is large. It is a space open to atmospheric pressure. Therefore, atmospheric pressure acts on the liquid levels of the temporary storage unit 46 and the storage tank chamber 20. Then, in the container 17, the atmospheric pressure acting on the liquid levels of the temporary storage unit 46 and the storage tank chamber 20 and "the spray liquid staying above the liquid level inside the container 17 act on the liquid surface. When the pressure and the pressure acting on the liquid level due to the air layer staying in the closed space 55 of the container 17 are balanced, the rise of the liquid level in the storage tank chamber 20 and the temporary storage portion 46 stops, and the storage tank When the spray liquid stored in the chamber 20 is not consumed, the supply of the spray liquid from the container 17 is stopped.

In this way, after the container 17 is stored in the storage chamber 16, the liquid levels in the temporary storage unit 46 and the storage tank chamber 20 rise integrally in response to the supply of the spray liquid from the container 17 for a while, and the liquid level becomes large. When the pressure balance related to the pressure is balanced, the rise of the liquid level is stopped and the supply of the spray liquid from the container 17 is stopped. Then, in the present embodiment, the position of the liquid level of the spray liquid stored in the storage tank chamber 20 is higher than the position P2 (see FIG. 6) in the storage tank chamber 20 regardless of the remaining amount of the spray liquid stored in the container 17. In the low state, the pressure balance related to the atmospheric pressure is balanced, the rise of the liquid level is stopped, and the supply of the spray liquid from the container 17 is stopped. That is, in the present embodiment, the position of the liquid level in the storage tank chamber 20 is always located at a position lower than the position P2 regardless of the remaining amount of the spray liquid stored in the container 17. Then, the position P2 is set to a lower position in the storage tank chamber 20 after satisfying the condition that the position is higher than the liquid suction port 54 of the outer pipe 53. Specifically, when the vertical length of the storage tank chamber 20 is set to "1", the position is set to be "1/3" lower than the position above the bottom surface of the storage tank chamber 20. The effect based on the above configuration will be described later.

As the consumption of the spray liquid by the spray unit 10 progresses, the container 17 will eventually become empty. As described above, the introduction path 21 is inclined downward from the temporary storage portion 46 toward the storage tank chamber 20, and is connected to the storage tank chamber side, which is a connection portion between the introduction route 21 and the storage tank chamber 20. The portion 52 is located above the liquid suction port 54 of the outer pipe 53 provided in the storage tank chamber 20. Therefore, when the container 17 is emptied and the spray liquid is further consumed by the spray unit 10, the temporary storage unit 46 is emptied first, and then the storage tank chamber 20 is emptied. Due to such a configuration, when the spray liquid does not remain in the storage tank chamber 20 and the mist cannot be sprayed by the spray unit 10, it is possible to prevent the liquid from remaining in the temporary storage unit 46. You can do it with.

For example, with the following configuration, the upper limit position of the liquid level in the storage tank chamber 20 can be made lower than the position P2 regardless of the remaining amount of the spray liquid stored in the container 17. That is, a sensor for detecting the position of the liquid level is provided in the storage tank chamber 20. Further, the liquid supply port 45 of the container 17 and the storage tank chamber 20 are connected by a flow path, and a pump is provided on this flow path, and the spray liquid is supplied from the container 17 to the storage tank chamber 20 while the pump is being driven. Then, while the pump is stopped, the supply of the spray liquid from the container 17 to the storage tank chamber 20 is stopped. Then, the position of the liquid level of the sensor is controlled by the detected value of the sensor, and the drive of the pump is controlled so that the position of the liquid level does not exceed the position P2 upward. Regardless of the remaining amount of the spray liquid to be stored, the upper limit position of the liquid level in the storage tank chamber 20 can be made lower than the position P2. However, in this case, it is necessary to provide a sensor and a pump, which leads to an increase in manufacturing cost, a complicated device structure, an increase in power consumption, and an increase in size of the housing 2. On the other hand, according to the present embodiment, the upper limit position of the liquid level in the storage tank chamber 20 is lower than the position P2 due to the balance of the pressure balance related to the atmospheric pressure. Does not occur.

Further, in the present embodiment, if the container 17 is attached to the holding mechanism 48, the spray liquid is automatically supplied to the storage tank chamber 20 via the temporary storage unit 46, so that the spray liquid to the storage tank chamber 20 is automatically supplied. At the time of supply, the user does not need to perform any special work other than attaching the container 17, which is highly convenient for the user.

As shown in FIG. 5, the spray unit 10 has an inner tube 56. The inner pipe 56 is erected in the central portion of the storage tank chamber 20 in a state of penetrating the bottom surface of the storage tank chamber 20. An air supply path 57 is formed through the inner pipe 56, and the lower end of the air supply path 57 is connected to an air supply path (not shown) to which compressed air is supplied from the air pump 11. The compressed air discharged by the air pump 11 is introduced into the air supply passage 57 of the inner pipe 56. At the tip of the inner pipe 56, an air supply port 58 communicating with the air supply passage 57 is provided.

The outer pipe 53 is externally formed in the inner pipe 56 in a state where a gap serving as a liquid flow path 59 through which the spray liquid flows is formed. The width of the liquid flow path 59 is about 1 to 2 mm. The outer pipe 53 is formed in a hollow columnar shape into which the inner pipe 56 can be inserted, and the position of the outer pipe 53 is fixed in a state of being positioned in the storage tank chamber 20 by a predetermined mechanism. A mist spout 60 communicating with the liquid flow path 59 is formed at the tip of the outer pipe 53, and a liquid suction port 54 is formed at the base end of the outer pipe 53. As shown in FIG. 5, when the liquid suction port 54 is exposed to the storage tank chamber 20 at the lowermost end of the storage tank chamber 20 and the spray liquid is stored in the storage tank chamber 20, the spray liquid is It is introduced into the outer tube 53 via the liquid suction port 54. As shown in FIG. 5, an outer pipe inner space 61, which is a space, is formed between the air supply port 58 of the inner pipe 56 and the mist spout 60 of the outer pipe 53.

As described above, the lid portion 24 is a lid member that covers the upper end opening of the storage tank chamber 20, and is provided with a mist discharge hole 26 through which the mist generated in the storage tank chamber 20 passes, and the mist communicates with the mist discharge hole 26. A spray port 39 for spraying is provided. A separation plate 33 is provided between the lid portion 24 and the outer pipe 53 at a position where the mist ejection port 60 of the outer pipe 53 faces. A bay-shaped curved surface 33a curved so as to be recessed upward is formed on the lower surface of the separation plate 33.

Under the above configuration, the spray unit 10 sprays mist in the following manner. In the following description, it is assumed that the container 17 in which the spray liquid sufficiently remains is stored in the storage chamber 16. When spraying the mist, the air pump 11 is first driven, and compressed air is introduced from the air pump 11 into the air supply passage 57 of the inner pipe 56. The compressed air introduced into the air supply passage 57 of the inner pipe 56 is discharged upward from the air supply port 58, and further discharged into the storage tank chamber 20 through the mist ejection port 60 of the outer pipe 53. At this time, the compressed air is discharged from the mist outlet 60, so that the outer pipe inner space 61 between the air supply port 58 of the inner pipe 56 and the mist outlet 60 of the outer pipe 53 becomes a negative pressure. As a result, the spray liquid that has entered the outer pipe 53 from the liquid suction port 54 of the outer pipe 53 is sucked upward through the liquid flow path 59 (see the arrow Y2 in FIG. 5), and the upper opening of the air supply port 58 is opened. A liquid film is formed along the surface, and this is torn off by the air discharged from the air supply port 58 of the inner pipe 56 to form a primary mist.

The primary mist ejected into the outer pipe inner space 61 in this way collides with the inner peripheral wall surface of the outer pipe 53 and is torn off by the impact and the share of the air flow due to the orifice effect, and a finer secondary mist is generated. Will be done. This secondary mist is ejected from the mist outlet 60 of the outer pipe 53 into the storage tank chamber 20 (see arrow Y3 in FIG. 5). The secondary mist ejected upward from the mist ejection port 60 collides with the bay-shaped curved surface 33a of the separation plate 33 provided above the mist ejection port 60. Here, the mist having a large particle size (hereinafter referred to as “coarse mist”) rebounds downward due to its large inertial force and is returned to the spray liquid stored in the storage tank chamber 20 (see arrow Y4 in FIG. 5). In this way, the coarse mist is rapidly recirculated to the spray liquid stored in the storage tank chamber 20 without coming into contact with the air outside the storage tank chamber 20. Therefore, the promotion of oxidation of the spray liquid stored in the storage tank chamber 20 is suppressed.

On the other hand, a mist having a fine particle size (hereinafter referred to as "fine mist") that does not return to the spray liquid stored in the storage tank chamber 20 has a small inertial force, and therefore is downward even if it collides with the bay-shaped curved surface 33a of the separation plate 33. It does not bounce back to, but rides on the air flow and diffuses horizontally beyond the edge of the separating plate 33 (see arrow Y5 in FIG. 5). The fine mist diffused horizontally beyond the edge of the separation plate 33 flows into the mist discharge hole 26 of the lid 24 along with the air flow, and is sprayed from the spray port 39 to the outside of the system through the mist discharge hole 26. Will be done.

Here, the atomizer 1 according to the present embodiment is a mobile atomizer, and it is required that the output air volume of the air pump 11 required for driving is as small as possible. This is because if it is possible to drive with a small output air volume, an air pump 11 having a small output can be used, and the power saving and miniaturization of the atomizer 1 can be realized. In particular, since the atomizer 1 according to the present embodiment is not configured to be driven by receiving power supplied from a commercial power source, power saving is strongly required. As described above, in the sprayer 1 according to the present embodiment, by introducing compressed air from the air pump 11 into the inner pipe 56, the venturi effect is utilized between the outer circumference of the inner pipe 56 and the inner circumference of the outer pipe 53. Since the spray liquid is sucked up through the liquid flow path 59 formed in the above to generate mist, the shorter the length of the inner pipe 56 and the outer pipe 53, and the shorter the length of the liquid flow path 59, the more the spray liquid is sucked up. The force required for this can be reduced, and the output air volume of the air pump 11 can be reduced.

Then, in the sprayer 1 according to the present embodiment, as described above, the upper limit position of the liquid level in the storage tank chamber 20 is set to a position lower than the position P2, and the upper limit position of the liquid level in the storage tank chamber 20 is low. That is, regardless of the amount of the spray liquid remaining in the container 17, the position of the liquid level in the storage tank chamber 20 is maintained at a low state below the position P2. Therefore, the inner pipe 56 and the outer pipe 53 can be sucked up by the Venturi effect to form a mist, and the condition that the tip of the inner pipe 56 is located above the position P2 is satisfied. The length of the air pump 11 can be shortened, and the output air volume of the air pump 11 can be reduced.

Further, since the sprayer 1 according to the present embodiment is a mobile sprayer, the work of supplying the spray liquid is performed in order to prevent the work of supplying the spray liquid from occurring frequently at the destination of the sprayer 1. It is required to make the time for continuous spraying of mist as long as possible. The longer spray time can be achieved by increasing the maximum amount of spray liquid that the spray unit 10 can consume in a single use. Then, in the sprayer 1 according to the present embodiment, the liquid supply unit 18 is provided as a separate body from the spray unit 10, and the container 17 stored in the storage chamber 16 of the liquid supply unit 18 is transferred to the storage tank chamber 20 of the spray unit 10. The structure is such that the spray liquid is supplied. Therefore, regardless of the maximum amount of the spray liquid that can be stored in the storage tank chamber 20, the maximum amount of the spray liquid that can be stored in the container 17 becomes the maximum amount of the spray liquid that can be used by the spray unit 10, and the mist spray time. Can be realized for a long time.

The mist spraying time can be lengthened by increasing the maximum amount of spray liquid that can be stored in the storage tank chamber 20 without providing the liquid supply unit 18, but it can be stored in the storage tank chamber 20. In order to increase the maximum amount of the spray liquid, it is necessary to increase the lengths of the inner pipe 56 and the outer pipe 53, which hinders the decrease in the output air volume of the air pump 11. On the other hand, in the present embodiment, it is possible to realize a long mist spraying time without increasing the lengths of the inner pipe 56 and the outer pipe 53, in other words, without increasing the output air volume of the air pump 11.

Next, an example of the usage mode of the atomizer 1 will be described. As described above, the atomizer 1 according to the present embodiment is a mobile atomizer and is used by being brought into a predetermined space. However, the atomizer 1 according to the present embodiment is particularly in the vehicle interior of the vehicle. It is supposed to be brought into and used in. Hereinafter, the usage mode of the atomizer 1 will be described assuming that the atomizer 1 is used in a vehicle. Further, the user is assumed to be a person who drives the vehicle.

First, the user prepares three containers 17 in which the following three types of spray liquids are stored as the containers 17. The first is a spray solution having an effect of awakening drowsiness, for example, a mint-based aroma oil containing a peppermint essential oil. Hereinafter, the spray liquid having the effect of awakening drowsiness is referred to as "drowsiness awakening liquid", the container 17 for storing the drowsiness awakening liquid is referred to as "drowsiness awakening container", and the mist based on the drowsiness awakening liquid is referred to as "drowsiness awakening mist". .. The second is a spray liquid having an effect of relieving fatigue, for example, an aroma oil containing an essential oil derived from an orange or a citrus fruit of Yuzu. Hereinafter, the aroma oil having the effect of recovering fatigue is referred to as "fatigue recovery liquid", the container 17 for storing the fatigue recovery liquid is referred to as "fatigue recovery container", and the mist based on the fatigue recovery liquid is referred to as "fatigue recovery mist". .. The third is a spray liquid having an effect of deodorizing the space provided with the sprayer 1. Hereinafter, the spray liquid having a deodorizing effect is referred to as a "deodorant liquid", the container 17 for storing the deodorant liquid is referred to as a "deodorant container", and the mist based on the deodorant liquid is referred to as a "deodorant mist". The structure of the holding mechanism 48 of the liquid supply unit 18 and the size of the storage chamber 16 correspond to the shape of the aromatherapy container 17 which is currently widely sold and widely used, and the user can use the commercially available container 17. By purchasing the container 17, the container 17 related to the above three types of spray liquids can be purchased. The provider of the sprayer 1 or the like may provide a set of three containers 17 related to the above three types of spray liquids as a set.

The user brings the atomizer 1 and the three containers 17 into the vehicle, and attaches the atomizer 1 to the holder. Hereinafter, attachment of the atomizer 1 to the holder will be described together with the structural features of the atomizer 1. Here, in recent years, drink holders have become widespread. The drink holder is a member to which a cylindrical object such as a can of juice or a cup is attached and supports the attached cylindrical object. Many vehicles are already equipped with drink holders, and such drink holders are sold by various means such as store sales and mail-order sales, and users can easily obtain drink holders. be able to.

FIG. 7 is a diagram showing an example of a drink holder. FIG. 7A is a side view of the drink holder 70 together with a cylindrical object attached to the drink holder 70, and FIG. 7B is a top view of the drink holder 70. Is. It is assumed that the height of the cylindrical object shown in FIG. 7A is the same as the height of the atomizer 1 according to the present embodiment.

The drink holder 70 illustrated in FIG. 7 is erected on a mounting table 71 on which a cylindrical object is placed and on the mounting table 71, and when the object is mounted, it comes into contact with the side surface of the object. A regulating member 72 that regulates the horizontal movement of the object, and a regulating member 72 that is attached to the regulating member 72, and when the object is attached, grips the object and presses the object against the regulating member 72. A pair of support portions 73 for positioning the position of the object with respect to the mounting table 71 are provided. As shown in FIG. 7B, each of the pair of support portions 73 is formed with an arc-shaped curved surface 73a, and the curved surface 73a is in contact with the side surface of the cylindrical object to form a cylindrical shape. Supports the object and stably fixes the cylindrical object. On the other hand, when a triangular prism or a square prism object is attached to the drink holder 70, the portion where the curved surface of the support portion 73 comes into contact is reduced, which is more stable than when a cylindrical object is attached. It will be in a state where it is not fixed to.

In the following description, it is assumed that the vehicle is provided with the drink holder 70 illustrated in FIG. 7 in advance. The drink holder 70 illustrated in FIG. 7 is just an example of a drink holder, and at present, drink holders having various shapes are widely used. However, the drink holders having various shapes basically have a bottomed cylindrical shape in which a support portion (for example, a cylindrical object into which the cylindrical object is inserted) is supported, as in the drink holder 70 illustrated in FIG. The support part) is provided, and the structure is such that a cylindrical object is stably supported by this support part.

The user attaches the sprayer 1 brought into the vehicle to the drink holder 70. Here, as described above, the three-dimensional shape of the housing 2 of the atomizer 1 is a shape that gradually changes from a circle to a number-corresponding shape from the lower end region to the upper end region. Therefore, the three-dimensional shape of the housing 2 in the range where the support portion of the drink holder 70 is expected to come into contact is close to a cylinder. In the drink holder 7070 illustrated in FIG. 7, the central portion of the sprayer 1 in the vertical direction is gripped by the support portion 73, but each cross section of the range in which the support portion 73 contacts is close to a circle and is supported. The three-dimensional shape in the range where the portion 73 is in contact is a shape close to a cylinder. As described above, the drink holder 70 stably supports the cylindrical object when it is attached, but the sprayer 1 according to the present embodiment assumes that the support portion of the drink holder 70 comes into contact with the support portion. Since the three-dimensional shape of the range to be formed is close to a cylinder, when the sprayer 1 is attached to the drink holder 70, it is stably supported by the support portion as in the case where a cylindrical object is attached.

After attaching the sprayer 1 to the drink holder 70, the user stores the drowsiness recovery container, the fatigue recovery container, and the deodorant container in each of the storage chambers 16 of the sprayer 1. The sprayer 1 may be attached to the drink holder 70 and the containers 17 may be stored in the storage chambers 16 before and after. As described above, the spray liquid is appropriately supplied from the container 17 to the storage tank chamber 20 according to the storage of the container 17 in the storage chamber 16, and the mist spraying can be started.

Here, it is widely known that a driver may experience a physical or psychological state of "sleepiness" or "fatigue" while driving a vehicle. Drowsiness occurs, for example, when sleep deprivation or when driving in a dull landscape for a considerable amount of time, and fatigue occurs, for example, when driving a vehicle for a long time. Occurs when operations related to driving occur frequently. Then, the sprayer 1 according to the present embodiment can awaken the drowsiness caused by the driver or recover the fatigue in a state where the drowsiness awakening container, the fatigue recovery container and the deodorant container are housed. Functions as a diffuser.

More specifically, when the user feels drowsiness, he / she operates the panel 13 to start spraying the drowsiness awakening mist based on the drowsiness stimulant. The drowsiness awakening mist is a mist containing a component having an effect of awakening drowsiness, and the drowsiness awakening mist is sprayed into the vehicle so that the user can smell the drowsiness awakening mist. Prompted. Similarly, when the user feels tired, he or she operates the panel 13 to start spraying the fatigue recovery mist based on the fatigue recovery liquid. Fatigue recovery mist is a mist containing a component having an effect of recovering fatigue, and the fatigue recovery mist is sprayed into the vehicle so that the user can smell the fatigue recovery mist, thereby recovering the user's fatigue. Prompted

Here, the timing at which the user starts spraying the mist by the sprayer 1 in anticipation of the effect of drowsiness awakening and fatigue recovery is often the case when the user is driving, and the drowsiness awakening and fatigue recovery are performed according to the mist spray. It is required that the effect of is shown to the user as soon as possible. Then, in order for the user to see the effects of drowsiness awakening and recovery from fatigue as soon as possible in response to the spray of mist, it is necessary for the sprayer 1 to spray a sufficient amount of mist having a fine particle size per unit time. .. Further, when the sprayed mist is not oxidized as much as possible, the effect of awakening drowsiness and recovery from fatigue can be accurately brought to the user.

As described above, the sprayer 1 according to the present embodiment is a method of spraying mist by introducing compressed air, sucking up the spray liquid by the Venturi effect, turning it into mist, and spraying it (hereinafter, referred to as "corresponding method"). ) Is adopted, and since only the mist having a fine particle size is discharged to the outside of the system by the separation plate 33, a sufficient amount of the mist having a fine particle size can be sprayed per unit time. Further, in the sprayer 1 according to the present embodiment, since the coarse mist is rapidly returned to the spray liquid by the separation plate 33, the promotion of oxidation of the spray liquid can be suppressed, and the mist in which the oxidation has not progressed as much as possible can be sprayed. ..

On top of that, the atomizer 1 according to the present embodiment has realized the miniaturization of the housing 2 and the power saving due to the reduction of the output air volume of the air pump 11 due to the above-mentioned structural features, and its size and its size. In terms of power consumption, it is very suitable as a sprayer 1 used in a vehicle. Here, as a method of spraying mist by a sprayer, in addition to the corresponding method, a method of generating mist by vibrating a liquid by ultrasonic waves and spraying, or a method of generating mist by a mist nozzle having fine spray holes formed thereof are used. There is a method of spraying. However, if a method other than the corresponding method is to be used to sufficiently spray fine mist to the extent that the same effects of drowsiness awakening and fatigue recovery as those of the sprayer 1 according to the present embodiment can be obtained, the present embodiment is used. It is extremely difficult to use the same power consumption and the same small size as the sprayer 1.

Further, as described above, in this example, in addition to the drowsiness awakening container and the fatigue recovery container, the deodorant container for storing the deodorant liquid is stored in the sprayer 1. The deodorant mist based on the deodorant liquid is sprayed, for example, in the following cases. That is, when the effect of awakening drowsiness or recovery from fatigue is obtained after spraying the drowsiness awakening mist or fatigue recovery mist, the user wants to quickly deodorize the inside of the vehicle and temporarily create a space without a specific scent. In such a case, the user sprays the sprayer 1 with a deodorant mist to deodorize the space inside the vehicle. Further, the vehicle may be driven not only by a specific user but also by a different user. In particular, when the vehicle is used for rental cars or car sharing, the vehicle is basically driven by an unspecified person. Then, after one user sprays the mist in the vehicle using the sprayer 1, when another user drives the vehicle in place of the one user, the other user once gives a specific scent. In such a case, the other user sprays the sprayer 1 with a deodorant mist to deodorize the space inside the vehicle.

That is, the inside of the vehicle is a closed and narrow space, and it is assumed that there is a real need to make the space inside the vehicle odorless once the mist is sprayed by the sprayer 1. Then, by accommodating the deodorant container for storing the deodorant liquid in the sprayer 1, it is possible to accurately meet such needs.

Here, in the present embodiment, the atomizer 1 includes three storage chambers 16 and can store up to three containers 17. The larger the number of storage chambers 16, the larger the size of the atomizer 1. As mentioned above, while driving, the driver may experience physical and psychological conditions of "sleepiness" or "fatigue", but "sleepiness" and "fatigue" adversely affect driving and who It is a typical symptom that occurs during driving in that it can occur even in the case of a driver, and there is a real need to alleviate at least these symptoms during driving. Further, as described above, the inside of the vehicle is a closed and narrow space, and there is a need to make the space inside the vehicle odorless once after the mist is sprayed by the sprayer 1. Since the sprayer 1 according to the present embodiment is provided with the minimum number (three) of storage chambers 16 necessary to satisfy these needs, the sprayer 1 is miniaturized to meet these needs. It is possible to meet.

Although an example of the usage mode of the sprayer 1 has been described above, it goes without saying that the usage mode of the sprayer 1 is not limited to the illustrated mode. For example, the place where the atomizer 1 is used is not limited to the inside of the vehicle, and may be, for example, a room of a house. Further, the container 17 housed in the sprayer 1 is not limited to the illustrated drowsiness awakening container, fatigue recovery container and deodorant container, and can accommodate containers 17 related to various types of spray liquids. In particular, in the present embodiment, mist based on a plurality of different (2 to 3) types of spray liquids can be sprayed at the same time, and the mist can be ejected in such an manner to enjoy the scent.

<Modification example>
Next, a modified example will be described. In the above-described embodiment, the outer peripheral shape of the upper end region of the housing 2 is a shape having three sides H and three connecting portions T having the same length. In this regard, the outer peripheral shape of the upper end region of the housing 2 is not limited to the shape according to the above-described embodiment. For example, it may be a circle, and for example, when there are M spray units 10 (M is an integer of 4 or more), M side H and M connection portions T connecting each side H are used. It may have a shape having.

FIG. 8 is a diagram schematically showing a state in which the housing 2 is viewed from above when the outer peripheral shape of the upper end region of the housing 2 is a circle. In FIG. 8, the components described in the first embodiment and the corresponding components are designated by the same reference numerals, and the description thereof will be omitted. FIG. 8 shows how the installation table 6 is formed with three storage chambers 20 related to the three spray units 10 and three storage chambers 16 related to the three liquid supply units 18. As described above, the position of the storage tank chamber 20 corresponds to the position of the spray unit 10, and the position of the storage chamber 16 corresponds to the position of the liquid supply unit 18.

As shown in FIG. 8, even when the outer peripheral shape of the upper end region of the housing 2 is a circle, the spray units 10 are separated by the same angle (120 ° in the case of the example of FIG. 8) on one virtual circle KS2. The spray units 10 can be efficiently separated from each other. Further, by arranging one liquid supply unit 18 in the space between the spray unit 10 and the spray unit 10, the dead space inevitably generated between the spray unit 10 and the spray unit 10 is effectively utilized to effectively utilize the liquid. The supply unit 18 can be efficiently arranged, and the housing 2 can be miniaturized. Although not shown, when the outer peripheral shape of the upper end region of the housing 2 has M side H and M connecting portions T connecting each side H, the same angle (360) is formed on the virtual circle. By arranging the M spraying units 10 in the vicinity of each of the M connecting portions T in a state of being separated by ° / M), each of the M spraying units 10 can be efficiently separated from the installation table 6. At that time, by arranging one liquid supply unit 18 in the space between the spray unit 10 and the spray unit 10, the size of the housing 2 can be reduced.

Although the embodiments of the present invention have been described above, all of the above embodiments are merely examples of embodiment of the present invention, thereby limiting the technical scope of the present invention. It should not be interpreted. That is, the present invention can be implemented in various forms without departing from its gist or its main features.

For example, in the above-described embodiment, the specific values of the dimensions of the member related to the atomizer 1 are appropriately described, but the dimensions of the member related to the atomizer 1 are not limited to the specific values exemplified. Needless to say, the shape and arrangement of each member according to the atomizer 1 is not limited to the shape and arrangement of each member illustrated in the embodiment. For example, the three-dimensional shape of the housing 2 is such that the circumscribed circle of the cross section gradually increases toward the upper side, but the circumscribed circle does not become as large as the illustrated housing 2. It may be present, and the size of the circumscribed circle of each cross section may be the same. Further, for example, although the shape of the connecting portion T is arcuate, it may be arcuate sharper than the illustrated housing 2 or may have a steep angle.
