According to the present invention, when the annular hollow structure and the wing portion are integrally formed, when the drug impregnating body is accommodated, the drug volatilization cartridge capable of volatilizing the drug and the drug volatilization cartridge containing the drug impregnating body are rotated. The present invention relates to a drug volatilization device that facilitates volatilization of a drug by using centrifugal force generated by rotation and a flow of air, and makes it possible to volatilize the drug continuously for a long time at a constant volatilization rate from the drug impregnating body.

Examples of chemical vaporizers that volatilizes and releases drugs in the entire enclosed space (for example, inside a building or a car, in a tent) to control pests such as mosquitoes and flies include mosquito coils, electric mosquito mats, Background Art An apparatus for volatilizing a drug using thermal energy from a liquid electric mosquito drug (liquid phase) or the like is known. Although chemical vaporizers of this kind generally use direct fire or electric energy as a heat energy source, there are cases where it is difficult to use them for safety or to secure a power source capable of generating sufficient heat energy. For example, in a situation where the use of direct fire, such as in a tent, is dangerous and there is no power source, it is preferable to use an apparatus capable of sufficiently volatilizing and releasing the chemical at room temperature.

An apparatus for volatilizing and releasing a medicament at room temperature without using thermal energy has been proposed before, and an apparatus for volatilizing and releasing a medicament using wind power such as a fan at room temperature is known. In this kind of apparatus, it is expected that the volatilization efficiency of a drug is greatly improved as compared with the case of simply leaving the drug (or drug impregnating body) to volatilize by using wind power from a fan or the like for volatilization of the drug.

Japanese Patent Application Laid-open No. Hei 10-191862 discloses a device for storing a granular drug impregnated body in a stationary impregnated container, and vaporizing the drug while stirring the drug impregnated body with wind by applying a wind from a fan to it. do.

However, in this apparatus, because the distance between the drug impregnated body and the fan is far from each other, the weak wind reaches the drug impregnated body. For this reason, in this apparatus, it is difficult to volatilize a medicine with a fixed volatilization amount from granular material which is a chemical | medical agent impregnation body over a long period of time, and the quantity of the drug volatilized decreases over time.

Japanese Patent Application Laid-Open No. 5-68459 uses a diffusion material formed by encapsulating a volatilizing agent in an envelope or a container having a membrane portion made of a gas-permeable film, or an envelope or a container having a ventilated microhole. Rotating discloses a device for diffusing a volatilizing agent into air.

However, it is difficult for the diffusion material used in the apparatus to volatilize the drug efficiently from the entire volatilizing drug, so that the volatilization amount of the drug decreases over time.

The present invention aims to solve the problems in the prior art drug volatilization device as described above, and it is possible to volatilize a stable drug over a long period of time, for example, 10 days or more, without using thermal energy. Provided is a cartridge for drug volatilization and a drug volatilization device based on the cartridge, which have many advantages of preventing the reduction of volatilization over time, applicability in the open air, sustaining excellent insecticidal effects, high safety, and good usability. It is.

MEANS TO SOLVE THE PROBLEM The present inventors researched in order to solve the said subject, and store the chemical | medical agent impregnation in the annular hollow structure which integrally formed the wing part, rotate the said hollow structure, and generate the airflow from the inner peripheral surface to the outer peripheral surface, As a result, it has been found that stable volatilization performance over a long period of time (for example, a period of 30 days with use of 12 hours per day) can be obtained by promoting volatilization of the drug, thereby completing the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

In the drug volatilization cartridge according to (1) and (2) and the drug volatilization apparatus according to (3), it is specifically proposed that centrifugal force is generated in the drug volatilization cartridge.

And, the size of the centrifugal force is determined by the rotation state of the drug volatilization cartridge. For example, the magnitude of the centrifugal force is 1/1000 to 100 times the gravity acceleration (9.8 × 10 ² cm / s ² ), specifically 9.8 × 10 ⁻¹ cm / s ^{2 to} 9.8 × 10 ⁴ cm / s ² . desirable.

The cartridge for drug volatilization according to (1) is composed of an annular hollow structure having a hollow portion for accommodating the drug impregnated body. The size of the hollow structure varies depending on the amount of the chemically impregnated body to be stored in order to obtain a desired amount of volatilization. In addition, although the shape of the said chemical | drug volatilization cartridge is arbitrary, it can use for example the thing of the spherical cross section of a hollow structure.

The hollow structure is composed of a main body member having an annular groove and a cover member which is a cover of the groove, which is preferable in terms of manufacturing the hollow structure, storing the chemically impregnated body into the hollow structure, and the like.

The annular hollow structure constituting the drug volatilization cartridge according to (1) has an opening on its outer circumferential surface and its inner circumferential surface, and the opening functions as a vent for vaporizing the drug. The opening can be arbitrarily designed as long as it has sufficient breathability, but it is preferable to set the ratio between the total area of the opening and the entire area of the peripheral surface of the cartridge for chemical vaporization, for example, from 1:10 to 1: 2.

The shape of the opening may be, for example, a configuration in which a net is fixed to an opening slit or a holder. Preferred are a plurality of opening slits formed in parallel.

In the cartridge for chemical volatilization according to the above (1), a wing portion extending toward the center of the hollow structure is integrally formed at a position not blocking the opening of the inner circumferential surface of the hollow structure. And the wing portion has a shape such as to promote the passage of air flow from the inner peripheral surface to the outer peripheral surface of the hollow structure by the rotation of the drug volatilization cartridge.

Although there is no restriction | limiting in particular about the length of the said wing part, It is preferable that it is at least 5 mm or more. The intensity of the air flow generated by the rotation of the drug volatilization cartridge can also be adjusted by changing its shape. For example, the longer the wing, the stronger the airflow generated. Moreover, when a wing part is made into a half moon shape or a curved shape, a wing part can send more air to the outer peripheral surface of a hollow structure.

At the center of the ring of the hollow structure constituting the drug volatilization cartridge according to (1), there is a rotation support shaft connected to the drive means for rotating the drug volatilization cartridge, and an axis center portion connected to the rotation support shaft. The shaft portion may be any configuration as long as it can connect the drug volatilization cartridge and the rotary support shaft loosely. For example, a circumferential member that does not loosely engage with the rotary support shaft can be used.

The shaft center portion and the hollow structure are hypothesized into a plurality of spoke portions. The number of spokes is arbitrary and it is preferable to join the hollow structure and the shaft center by, for example, 2 to 4, in particular 3 or 4 spokes.

In the cartridge for drug volatilization according to (2), although the conventional drug impregnating body is accommodated in the drug volatilization cartridge of (1), the medicine compartment stored in the drug volatilization cartridge according to (2) before use For the purpose of preventing the chemicals from volatilizing from stagnation, it is preferable to attach a shielding member such as a seal tape to the opening of the cartridge for chemical volatilization. Since the said shield member must be removed at the time of use, the adhesive tape etc. which can peel easily are preferable.

The chemically impregnated body used in the cartridge for chemical volatilization according to the above (2) can be changed in various ways, and is granular, for example, spherical, ellipsoidal, oval, columnar, It may be rectangular, rod-shaped, disc-shaped, square-plate, irregular shape or the like.

From the viewpoint of preventing the scattering of the chemically impregnated body, it is necessary to at least make the size of the outer peripheral surface opening and the inner peripheral surface opening in the cartridge for chemical volatilization according to (2) above.

Particularly preferred is a granular drug impregnated body having an average outer diameter of 3 mm to 10 mm and 1.3 times or more the size of the opening. By employing the drug impregnated body having such a size and shape, the drug inside the drug impregnated body gradually migrates to the surface, and it is possible to maintain a stable amount of volatilization over a long period of time. On the other hand, for example, in the drug impregnation body whose average outer diameter is smaller than 3 mm, the drug is rapidly volatilized rapidly, and there is a problem in the persistence of the insecticidal effect.

The drug impregnated body has a porosity in the drug volatilization cartridge [% of internal volume remaining as voids without filling the drug impregnated body] 20% to 70%, preferably 25% to 65%, particularly preferably Is stored between 30% and 60%. If the porosity is less than 20%, air is difficult to flow through the drug volatilization cartridge, and a sufficient amount of drug volatilization cannot be secured. On the contrary, when the porosity exceeds 70%, since the time for contacting air and the drug impregnating body becomes short when passing through the drug volatilization cartridge, a sufficient amount of drug volatilization cannot be secured.

It is preferable that the said chemical | medical agent impregnation body contains the chemical | medical agent which can adjust the amount of volatilization per hour to 0.01-0.6 mg, and can exhibit sufficient insecticidal effect by this chemical quantity. As such a medicament, a volatile pyrethroid insecticide is mentioned. The volatilizing pyrethroid insecticide is, for example, a fluorine-substituted benzyl alcohol ester compound represented by the formula (1).

Formula 1

Wherein X and Y represent the same or differently hydrogen atom, methyl group, halogen atom or trifluoromethyl group, and Z represents hydrogen atom, fluorine atom, methyl group, methoxymethyl group or propargyl group.

As a specific example of the compound represented by the said Formula (1), 2, 3, 5, 6- tetrafluorobenzyl- chrysanthite, 2, 3, 5, 6- tetrafluorobenzyl-2, 2-dimethyl-3- ( 1-propenyl) cyclopropanecarboxylate, 4-methyl-2, 3, 5, 6-tetrafluorobenzyl-xanthate, 4-methyl-2, 3, 5, 6-tetrafluorobenzyl-2 , 2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate, 4-methyl-2, 3, 5,6-tetrafluorobenzyl-2, 2-dimethyl-3- (2,2-dichloro Vinyl) cyclopropanecarboxylate, 4-methoxymethyl-2, 3, 5, 6-tetrafluorobenzyl-xanthate, 4-methoxymethyl-2, 3, 5, 6-tetrafluorobenzyl- 2, 2-dimethyl- 3- (1-propenyl) cyclopropanecarboxylate, 2, 3, 4, 5, 6-pentafluorobenzyl-2, 2-dimethyl- 3- (2-chloro- 2- Trifluoromethylvinyl) cyclopropanecarboxylate or 4 Propargyl-2, 3, 5, may be mentioned 6-tetrafluoro-benzyl-3- (1-propenyl) -2,2-dimethyl cyclopropanecarboxylate. Moreover, as a compound other than what is represented by the said General formula (1), 4-methoxymethyl-2, 3, 5, 6- tetrafluorobenzyl-2, 2, 3, 3- tetramethylcyclopropanecarboxylate, and 4 -Propargyl-2, 3, 5, 6- tetrafluorobenzyl-2, 2, 3, 3- tetramethylcyclopropane carboxylate is mentioned.

The compounds also include asymmetric carbons and double bonds, optical and geometric isomers. However, of course, any mixture between the isomer and the isomer may be used as the medicament.

Moreover, the said chemical | medical agent impregnation body may contain 1 type of drugs, or may contain the mixture of 2 or more types of drugs.

On the other hand, it is not preferable to use aspirin, prarethrin, and the like, which have been conventionally used as an active ingredient of a heating evaporative insecticide, in the chemical vaporization apparatus of the present invention because of their insufficient volatilization at normal temperature. Moreover, even if it is a pyrethroid type insecticide, since the drug like empentrin which shows a high vapor pressure exerts an effective insecticidal effect, since it requires a volatilization amount of 2 mg or more per hour, it is likewise not preferable.

The drug impregnated body preferably contains 60 mg or more of the drug. When content of a chemical | medical agent is less than 60 mg, there exists a possibility that the sustainability of an insecticidal effect may arise. At the time of impregnation of a chemical | medical agent, a solvent, a diluent, surfactant, a dispersing agent, a slow-release agent, etc. can be used as desired, and various impregnation means conventionally known can be employ | adopted. The drug impregnating agent may contain a stabilizer, a flavoring agent, a colorant, an antistatic agent, and the like, as long as it does not interfere with the volatilization of the drug, and furthermore, hinokitiol, carbon, safrole, and citronone. It is also possible to add other highly volatile insecticides and repellents such as insect repellents such as rolls and cinnamic aldehydes, mite insecticides, fungicides, deodorants and the like to form a multipurpose pharmaceutical composition.

Examples of the material of the chemically impregnated body include cellulose carriers such as paper, pulp and viscose, synthetic resin carriers such as ethylene-vinyl acetate resin and olefin polymer, and inorganic carriers such as calcium silicate. Especially, it is preferable to use as a base material the paper, pulp, a cellulose carrier, a synthetic resin carrier, or a mixture thereof derived from nature.

In the cartridge for drug volatilization according to the above (2), various types of drug impregnated bodies having different sizes, shapes, drugs, materials, and the like may be mixed at an appropriate ratio and stored in the cartridge for drug volatilization. By simultaneously using a drug impregnating body having different volatilization properties and efficacy, the drug volatilization device of the present invention can achieve a complex insecticidal and insect repellent effect.

In the chemical | medical agent volatilization apparatus of said (3), the drive means which rotates the said chemical | medical agent volatilization cartridge consists of a motor and a power supply, and is integrated in the apparatus main body. In view of prolonging the usable time of the drug volatilization device, it is preferable that the motor is a power saving type. For example, a battery having a voltage of 2.0 to 3.0 V is suitable for maintaining a rotational speed of 500 to 2000 rpm for more than 300 hours. The power supply may be a battery such as a dry battery or an AC power source of 3.0 to 6.0 V obtained by converting an AC power source. In addition, even when an AC power source is used with an emphasis on more stable chemical vaporization performance and economical efficiency, it is preferable to design the battery so that it can be used together for outdoor use, for example.

In the present drug volatilization device according to (3), various elements of the above-described components, for example, the size of the drug volatilization cartridge, the total area of the opening provided in the drug volatilization cartridge, the size and shape of the wing portion, and the drug volatilization By changing the amount and filling rate of the drug impregnated body to be contained in the cartridge, the type and amount of the drug contained in the drug impregnated body, the size and shape of the drug impregnated body, the rotation speed of the drug volatilization cartridge, etc. The volatilization amount of the drug and the duration of the drug volatilization can be arbitrarily changed. The chemical | medical agent volatilization apparatus comprised especially so that a chemical | medical agent may volatilize from 0.01-0.6 mg per hour, and over 180 hours from a chemical | medical agent impregnation body is especially preferable at the point of actual use. The remaining amount of display method can be appropriately employed, and can be represented by, for example, a rod-shaped case using liquid crystal, or a reduction in the number of divided marks, and to further clarify the replacement time of the cartridge or the battery. The display may be flickered at the end point.

Hereinafter, the apparatus of the present invention will be described in more detail with reference to the drawings.

FIG. 5 is a perspective view showing the drug volatilization cartridge 2 according to (1) and (2) from above, FIG. 6 is a perspective view showing the same drug volatilization cartridge 2 from below, and 7 is a perspective view showing the same drug volatilization cartridge 2 in a disassembled state.

Moreover, the outer peripheral surface opening part 22 and the inner peripheral surface opening part 23 are provided in the inner peripheral surface and outer peripheral surface of the chemical | medical agent volatilization cartridge 2, respectively. The outer circumferential surface opening 22 and the inner circumferential surface opening 23 are both a plurality of slits formed in parallel, and function as vent holes through which the chemicals in the chemically impregnated body 3 volatilize. The larger the size of the outer circumferential surface opening 22 and the inner circumferential surface opening 23 is, the higher the volatilization speed of the drug is.

In addition, on the inner circumferential surface of the drug volatilization cartridge 2, a plurality of wings 26 are provided which extend toward the center of the ring of the drug volatilization cartridge 2. These wing | blade parts 26 are formed integrally with the chemical | medical agent volatilization cartridge 2 so that the inner peripheral surface opening part 23 may not be blocked, and the shape is curved plate shape. And the wing part 24 accelerates the passage of the airflow which flows from the inner peripheral surface of the said hollow structure 21 to the outer peripheral surface by rotating the cartridge for chemical vaporization.

Thus, the curved wing | blade part 26 can take more air and can send a strong airflow.

The chemical vapor volatilization cartridge 2 according to the above (1) and (2) has an axial center portion 25 at the center of the ring of the hollow structure 21. In the illustrated embodiment, the shaft center portion 25 is a circumferential member that claws together with the rotary support shaft 24 so as not to loosen with each other. And the shaft portion 25 is connected to the hollow structure 21 by the spoke portion (27).

The drug volatilization cartridge 2 according to the above (1) and (2) comprises a main body member 28 in the shape of an annular groove and a cover member 29 serving as a cover of the groove. The manufacture of the cartridge 2 and the storage of the chemically impregnated body 3 into the hollow structure 21 are facilitated. Engagement of the main body member 28 and the lid member 29 can be achieved by, for example, pod engagement with a rib provided on the surface of the lid member 29, but both may be bonded using an adhesive or the like.

1 is a perspective view showing the form of a device for drug volatilization according to the above (3), FIG. 2 is a front view showing the same device for drug volatilization, FIG. 3 is a side view showing a device for drug volatilization, and 4 is a cross-sectional view schematically illustrating a cross section taken along the line AA ′ of FIG. 2.

As shown in FIG. 1-4, the chemical | medical agent volatilization body 3 in which the chemical | medical agent volatilization cartridge 2 is inserted in the reception main part 11 of the apparatus main body 1, and rotation is supported freely is carried out.

In addition, the chemical | medical agent volatilization cartridge 2 may be a structure like it is covered by the cover 6 so that it may not be exposed.

In the case of the embodiment shown in FIG. 1, the apparatus main body 1 puts the chemical | medical agent volatilization cartridge 2 in the receiving main part 11, and incorporates the drive means which consists of the motor 4 and the battery 5, However, the receiving main portion 11 is not necessarily indispensable in the drug volatilization device according to the above (3). The apparatus main body 1 has a power switch 12 for controlling the driving / stopping of the chemical vaporization cartridge 2 on the surface thereof, and furthermore, the opening 13 is preferably provided so as not to interfere with the chemical vaporization. Do.

In addition, the holder 14 is installed on the back of the apparatus main body 1 (opposite to the surface on which the drug volatilization cartridge is installed) to be attached to the garment, or to the affected part 15 provided on the upper portion of the apparatus main body 1. Hanging around the neck through a string makes it very easy to carry the drug volatilization device. In addition, in terms of portability, the size of the apparatus main body 1 is preferably as small as possible.

As shown in FIG. 4, the drug impregnation body 3 is housed in the hollow structure 21 of the drug volatilization cartridge 2. The drug impregnation body 3 does not necessarily need to be densely packed in the hollow structure 21. This is caused by the centrifugal force generated by the rotation of the drug volatilization cartridge 2, and the drug impregnated body 3 is pushed on the outer circumferential surface side of the drug volatilization cartridge 2 so that the drug impregnated body is near the outer circumferential surface of the drug volatilization cartridge 2. This is because the dense state of charge of (3) is achieved.

The motor 4 is placed under the medicine volatilization cartridge 2 and is attached to the apparatus main body 1 by the motor mounting portion 16. The motor 4 is connected with the rotary support shaft 24 of the drug volatilization cartridge 2, and the rotary support shaft 24 is further connected with the shaft center portion 25 of the drug volatilization cartridge 2. The connection between the motor 4 and the rotary support shaft 24, and also the rotary support shaft 24 and the shaft center portion 25 must be strong enough so that no slip occurs when the motor 4 is driven. 3) When all the chemicals in the container are consumed and the cartridge 2 for chemical vaporization is replaced, it is preferable that the cartridge 2 for chemical vaporization and the motor 4 can be easily separated.

The motor 4 is driven by the battery 5 housed in the apparatus main body 1. In order to replace the battery 5 at the end of its life, it is preferable to provide an opening for the battery replacement in the apparatus main body 1.

Since the chemical | medical agent volatilization cartridge 2 rotates at high speed at the time of use, the chemical | medical agent volatilization apparatus of said (3) receives the accommodating main part 11 of the apparatus main body 1 in order to prevent the finger etc. from accessing the chemical | medical agent volatility cartridge 2, and so on. ) And covered by the cover (6). The cover 6 should be provided with an opening 61 so as not to inhibit the volatilization of the medicament. Preferably, the size of the opening 61 is as large as possible. In the case where the strength of the cover 6 is lowered due to the enlargement of the size of the opening 61, a reinforcing part 62 is provided on the surface of the cover 6. Thus, the size of the opening 61 can be enlarged while securing the strength of the cover 6.

Moreover, it is preferable to provide the opening / closing switch 63 for opening / closing the cover at the time of replacing the chemical vapor cartridge 2.

Although there is no restriction | limiting in particular about the material of the apparatus main body 1, the chemical | medical agent volatilization cartridge 2, and the cover 6, It is preferable to manufacture with plastic resin from a viewpoint of productivity, moldability, price, weight, etc.

As shown in Table 1, according to the chemical | medical agent volatilization apparatus of this invention, it was recognized that the volatilization amount of a chemical | medical agent is stabilized over a long period of 30 days, and maintains high insecticidal effect in the meantime. That is, when the chemical volatilization device according to (3) provided with the cartridge for chemical volatilization of the type 1 is used, there is almost no change in the amount of volatilization over time, and the insecticidal effect is almost constant over 30 days, and excellent time-lapse It was confirmed that it has ever-intrinsic stability.

On the other hand, as shown in Table 2, in the drug volatilization cartridge of Comparative Example 1 in which the hollow structure for accommodating the drug impregnated body and the wing portion were separately formed, the drug volatilization device according to (3) of Example 1 In comparison, it was clearly inferior to the volatilization efficiency.

The drug volatilization cartridge of the present invention, in which the blade part is integrally formed with the hollow structure, is used for the drug volatilization of the comparative example when the cartridge for drug volatilization of the comparative example in which the hollow structure accommodating the drug and the wing part as a separate member is compared. In the cartridge, an annular support portion (having a structure similar to that of the inner circumferential surface portion of the hollow structure) for supporting the respective wing portions is required, whereas such a support and return portion is unnecessary in the cartridge for chemical volatilization according to the above (1). Therefore, the drug volatilization cartridge of the present invention can make the length of the wing portion longer, thereby generating a stronger air flow, and can reach the chemically impregnated body as it is without weakening the air flow generated by the wing portion. have. For this reason, forming the wing portion for generating air flow integrally with the hollow structure is helpful to improve the volatilization efficiency. In addition, integration of the wing portion and the hollow structure is advantageous in terms of productivity since the wing portion and the hollow structure need not be manufactured separately and then assembled together. In particular, in the case of separately manufacturing the wing parts assembled and attached to the hollow structure, it is necessary to be careful not to block the opening provided in the inner circumferential surface of the hollow structure, the assembly and attachment is quite cumbersome. However, in the case of integrally molding the hollow structure and the wing portion, by installing the wing portion at a position other than the opening portion at the design stage, the opening portion of the inner circumferential surface of the hollow structure can not be blocked, and the productivity is greatly improved even at this advantage.                     

In the cartridge for drug volatilization according to the above (2), the drug volatilization cartridge containing the drug impregnation body is rotated by the driving means, whereby the drug is volatilized at normal temperature while the centrifugal force acts on the drug impregnation body. In this case, the centrifugal force acting on the drug impregnated body exhibits various effects as exemplified below, and contributes to stable volatilization over a long period of time of the drug.

1) The chemical | medical agent impregnation body is previously accommodated in the state suitable for a chemical vaporization cartridge. However, since the individual drug impregnation body is not fixed, the drug impregnation body moves when an impact is added to the drug volatilization cartridge or the drug volatilization cartridge is moved, and the drug impregnating body in the drug volatilization cartridge is stored. The state changes. However, when the centrifugal force acts on the chemical | medical agent impregnation body at the time of use, the chemical | medical agent impregnation body is pushed and pressed by the outer peripheral surface side of a chemical | medical agent volatilization cartridge, and a suitable accommodating state is reproduced.

2) When the action of the centrifugal force on the drug volatilization cartridge is released, the individual drug impregnating bodies move freely to some extent by the rotation or movement of the drug volatilization cartridge, and the position thereof is changed. Therefore, the individual drug impregnated bodies can be moved by applying or releasing the centrifugal force to the drug volatilization cartridge, and the effect can be as if the drug impregnated bodies are stirred.

3) When centrifugal force is applied to the drug impregnated body, since the drug inside the drug impregnated body is pushed out to the surface by centrifugal force, and the transpiration is promoted by the airflow generated by the rotation of the cartridge for drug volatilization, the drug impregnated body The drug in the inside of the can be effectively increased.

The drug volatilization device according to the above (3) is a method of promoting volatilization of the drug from the drug impregnating body by airflow due to unheating, so that there is no worry of burns at the time of use, and it is possible to stably maintain a certain amount of drug over a long period of time. It can volatilize and maintains the outstanding pesticidal effect for a long time. Furthermore, since it is excellent also in safety, usability, etc., it is extremely useful for the control of unpleasant pests, such as mosquitoes and fly sanitary pests, fly hawks, yusrica, moth moths, koga, bonito worms, especially mosquitoes.

In addition, since the chemical vaporizer according to the above (3) can be made compact and lightweight, it can be applied regardless of indoors or outdoors. For example, it is a sanitary pest in a tent in a room or a camp at a destination. It is very helpful for the control of pests and unpleasant pests.

In the case of the drug volatilization cartridge used in the drug volatilization device according to the above (3), the hollow structure and the wing portion accommodating the drug impregnating body are integrally formed, thereby generating a stronger air flow and weakening the air flow. It is possible to reach the drug impregnated body as it is, and this contributes to the improvement of volatilization efficiency. In addition, since the wing portion and the hollow structure are separately manufactured, there is no need to assemble both of them later, and cumbersome positioning between the hollow structure and the wing portion at the time of assembly can be omitted, which is very advantageous in terms of productivity.

The present invention can be used for the purpose of a wide range of pest control in the outdoors or indoors.
