BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blower-type chemical volatilization device for releasing volatile chemicals into the atmosphere for the purpose of insecticidal, repellent, deodorant, fragrance, sterilizing, antibacterial, antifungal, etc. Is.

[0002]

2. Description of the Related Art Japanese Unexamined Patent Publication (Kokai) No. 9-19255 discloses a blower type chemical volatilization device which blows air on an air freshener and releases its scent into the atmosphere. This blast type chemical volatilization device
It is provided with a cap-shaped fitting member having a plurality of through holes, a motor and a rotary blade provided in the fitting member. The fitting member is fitted to the case body containing the fragrance. In this state, the motor rotates the rotary vanes to blow air to the fragrance in the case body to release the scent into the atmosphere.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned air blowing type chemical volatilization device, the air in the atmosphere is sucked from the through hole of the fitting member by rotating the rotary blade, and the air blown back to the fragrance is repelled. It is discharged to the atmosphere through the above-mentioned through hole. The fragrance is released into the atmosphere together with the air discharged into the atmosphere.

For this reason, the inhaled air and the ejected air mix when passing through the same through hole, and the fragrance released to the atmosphere by the ejected air is blown again to the fragrance. is there. Therefore, the release of the fragrance into the atmosphere is not smooth. Moreover, the direction in which the fragrance is released into the atmosphere is unknown, and the fragrance cannot be efficiently released in a predetermined direction in an irregular manner.

The present invention has been made to solve the above problems. A first object of the present invention is to provide an air-blowing type drug volatilization device capable of smoothly releasing a drug into the atmosphere. A second object of the present invention is to provide an air-blowing type drug volatilization device capable of efficiently discharging a drug in a predetermined direction.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The present invention is not limited to the embodiment shown in the drawings. FIG. 1 is a sectional view of an air blowing type chemical volatilization device according to a first embodiment of the present invention. The blown-type chemical volatilization device 1 includes a device body 2 and
The blower 3 provided in the apparatus main body 2 is provided. The apparatus main body 2 has a medicine container holding portion 4 and an air flow passage 5 that passes through the medicine container holding portion 4 and is continuous inside and outside the apparatus main body 4. By driving the blower 3, the air flows inside and outside the apparatus main body 2 along the air flow passage 5. The circulating air passes through the medicine container holding unit 4.

Next, an example of use of the air blowing type chemical vaporization device 1 described above will be described. The drug container 20 containing the volatile drug 6 is held in the drug container holder 4 and the blower 3 is driven. Air circulates inside and outside the apparatus main body 2, and the chemical that has volatilized along with the circulating air is released into the atmosphere.

Next, the specific shape will be described. Device body 2
Is a container shape having an upper hollow portion 13 and a lower opening portion 14 with an upper surface plate 10, a peripheral surface plate 11 and a partition plate 12. The lower opening portion 14 is the drug container holding portion 4 described above. A suction port 15 opening to a lower opening 14 is formed near the lower part of the peripheral plate 11. A discharge port 16 is formed in the upper hollow portion 13 near the upper portion of the peripheral plate 11. The partition plate 12 is formed with a vent hole 17 which connects the upper hollow portion 13 and the lower opening portion 14 to each other. The suction port 15, the ventilation port 17, and the discharge port 16 form the air flow passage 5 described above.

The blower 3 drives the fan 18 to rotate by an electric motor 19, and is a sirocco fan in this embodiment. The electric motor 19 is attached to the upper plate 10, and the fan 18 is rotationally driven in the upper hollow portion 13. The suction side of the blower 3 faces the ventilation port 17, and the discharge side of the blower 3 faces the discharge port 16. The electric motor 19 may be driven by a commercial power source or a dry battery.

The medicine 6 is granular and is contained in a medicine container 20. As shown in FIG. 2, the drug container 20 is a sealed pull-top type can container that has a container body 21 and a lid 22, and the lid 22 can be easily opened by pulling a pull-top portion 23. The container body 21 has a shape that is detachably fitted to the lower opening 14.

Since the medicine 6 is sealed in the medicine container 20, the medicine 6 does not flow out or deteriorate when not in use, and a wide range of volatile medicines 6 can be used. In addition, it is easy to handle. In addition, the lid 22 can be easily removed by pulling the pull-top portion 23 at the time of use, and it is easy to open the lid.
