Description

[0001]
BACKGROUND OF THE INVENTION
The present invention attaches a medicine holder holding a volatile medicine for purposes such as insecticidal, repelling, deodorizing, fragrance, antibacterial and antifungal to an apparatus main body equipped with a blower fan, More particularly, the present invention relates to a drug diffusing apparatus provided with a plurality of attachment portions for attaching a drug holder provided in the apparatus main body.
[0002]
[Prior art]
Conventionally, as a medicine diffusion device, a medicine holding body that holds a medicine is attached to an apparatus main body provided with a blower fan, and a medicine in the medicine holding body is diffused by a blower fan of the apparatus main body.
[0003]
In recent years, in such a drug diffusion device, a drug diffusion device for pest control has been widely used. This pest control drug diffusion device is a set of a drug holder that holds a volatile drug and a device main body that is attached to the drug holder and releases the drug in the drug holder by a blower fan. It was commercially available.
[0004]
As drug holders for holding this drug, products such as those for different use periods, for example, for 1 month and for 3 months, are currently available within the same dosage range. In the future, it will be possible to hold several types of drugs, such as spaces of different sizes, such as for small rooms of about 6 tatami mats to large rooms with several tens of tatami mats, or for pests to be controlled. It is thought that scenes using the body often increase.
[0005]
Therefore, when preparing several types of drug holders, it can be dealt with by increasing / decreasing the amount of drug stored inside, for example, the amount of carrier impregnated with the drug, but in this case, the thickness of the drug holder is reduced. If the number is increased or decreased, there is a possibility that the state of aeration of the air passing through the medicine holding body inevitably changes, thereby causing a problem that the diffusion of the medicine changes.
[0006]
Therefore, instead of increasing or decreasing the thickness of the drug holding body, the area of the drug holding body, that is, the size of the outer shape, is made different so that the aeration state of the air passing through the drug holding body is made constant and the drug is diffused. It was considered that it would be a good idea to prepare several types of drug carriers without changing the above.
