Description

  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 infectious diseases transmitted by pests (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 Utility Model Publication 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 object of the present invention is to efficiently introduce both the insecticidal components released by the combustion of the insecticide and the ions generated by the ion generator into the air with a simple configuration. It is an object of the present invention to provide an insecticidal device that can simultaneously prevent a disease caused by a pest and a disease caused by a fungus or a virus.

  The insecticidal apparatus according to the present invention is an insecticidal apparatus that distributes an insecticidal component in the air, contains an insecticide that releases the insecticidal component by burning, and has two openings that communicate with each other so as to face each other. An air passage and an ion generator for generating ions through a communication port communicating with the air passage, and utilizing the air flow due to the draft effect generated in the air passage when the insecticide burns, It is characterized in that ions generated by the ion generator are discharged to the outside.

  In the insecticidal apparatus according to the present invention, the air passage has a housing portion for housing the insecticide in the middle between the two openings, and the housing portion for the insecticide and one of the two openings. The communication port is provided between the two.

  The insecticidal apparatus according to the present invention includes 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 secondary battery.

  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.

  The insecticidal apparatus according to the present invention includes a housing that surrounds the air passage and the ion generator, and the housing on the opening side in which the communication port is located between the two openings and the insecticide containing portion. A base end portion is fixed to the end portion, and a hanging tool having a hook shape in the tip end portion is provided.

In the present invention, the insecticidal device includes an air passage and an ion generator.
The ventilation path contains the insecticide. Insecticides release vaporized insecticidal components by burning themselves. 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 two openings that face each other and communicate with the outside. 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 air passage contains the insecticide, the insecticidal component released from the insecticide flows through the air passage. Then, an air flow by a draft effect (chimney effect) is generated 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 air passage is provided in the lateral direction, or if the air passage is open only on the upper side or the lower side, the air flow due to the draft effect is unlikely to occur, so that the insecticidal component is distributed efficiently.

The ion generator generates ions through a communication port communicating with the air passage. For this reason, the generated ions are released into the air passage and flow out to the outside through the upper opening of the air passage together with the air containing the insecticidal component. That is, ions can be efficiently discharged to the outside by using an air flow 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 communication port for releasing ions into the air passage has an air passage between the insecticidal container and one of the two openings in the middle between the two openings of the air passage. Communicating with For this reason, since ions are released through the communication port with respect to the air flow flowing to one of the two openings through the insecticide accommodation portion due to the draft effect, ions can be released to the outside more efficiently.

In the present invention, the insecticidal apparatus further includes a power supply unit.
The power supply unit supplies power to 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 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 with a solar cell can be supplied to an 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 apparatus of the present invention, the air generated by the draft effect generated in the air passage by the combustion of the insecticide is used to release the insecticidal components released by the combustion of the insecticide and the ions generated by the ion generator to the outside. Since it discharges | emits, it is not necessary to provide an air blower, and both an insecticidal component and ion can be efficiently diffused in the air by the simple structure which contributes to energy saving with small size and light weight. 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 with reference to the drawings illustrating embodiments thereof.

Comparative Example FIG. 1 and FIG. 2 are a front perspective view and a rear perspective view schematically showing an appearance of an insecticidal apparatus 1 as a comparative example 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. 1-5, the 1st container 121 (and 2nd container 122) of the apparatus main body 12 is made into the 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 central portion to the lower portion in the vertical direction (arrow A1 direction). 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 portion of the second container 122 and is disposed from the upper portion of the second container 122 to the central portion 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 distal ends of the partition walls 423 and 424 are in 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 ventilation path 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 battery 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.

  An inclined surface that guides the air exhausted from the second air passage 42 toward the exhaust port 412 is formed around the exhaust port 422 (for example, an inclined surface at the top 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 uses both H ⁺ (H ₂ O) _n (n is an arbitrary integer) that is a positive ion and O ₂ ⁻ (H ₂ O) _m (m is an arbitrary integer) that is a negative ion. 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 provided 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 able to switch between a case where positive and negative ions are generated and a case where negative ions are mainly 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 FIG. 7 is a longitudinal sectional view schematically showing an internal configuration of an insecticidal apparatus 1 according to an embodiment of the present invention, and corresponds to FIG. 5 of a comparative example.
FIG. 8 is a block diagram showing a main configuration of the insecticidal apparatus 1 according to the embodiment of the present invention, and corresponds to FIG. 6 of the comparative example.

The insecticidal apparatus 1 according to the embodiment of the present invention has substantially the same configuration as the insecticidal apparatus 1 of the comparative example. However, although the insecticidal apparatus 1 of the comparative example includes the second container 122 in which the blower 22 is built, the insecticidal apparatus 1 in the embodiment of the present invention has the second container 123 in which the blower 22 is not built. It has.
The second container 123 corresponds to the second container 122 of the comparative example, 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 comparative example. Further, the intake port 421, the exhaust port 422, and the opening 426 are not formed.

  As shown in FIG. 7, 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. 8, 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.
In addition, the same reference numerals are given to portions corresponding to the comparative example, and the description thereof is omitted.

The insecticidal apparatus 1 according to the embodiment of the present invention as described above uses the convection due to the draft effect for the insecticidal components contained in the mosquito coil M and the positive and negative ions generated by the ion generator 21. There are substantially the same effects as the insecticidal apparatus 1 of the comparative example, such as being able to be efficiently released into the air.
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.

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.
Moreover, as long as there exists an effect of this invention, the component which is not disclosed by embodiment may be contained in the insecticidal apparatus 1. FIG.
