I have.

[0003]

In the above-mentioned prior art, in the first case, the vaporized drug evaporates to the outside of the apparatus body through the net-shaped upper lid, so that the vaporized drug adheres to the upper lid. However, there is a problem in that the opening of the net-shaped upper lid is closed, and the amount of drug evaporated decreases. In the second case, the distance between the heating element and the transpiration port is 0.5 to 2.5.
A gap having a distance of about 1 cm is provided, and the drug evaporates due to the inflow of strong cross wind from the outside of the apparatus main body, and does not flow to the evaporation port. There was a possibility that the problem of adhesion would occur. The present invention aims to solve these problems.
That is the subject.

Further, the shapes of the apparatus main body 1 and the container 13 are not limited to the embodiment, but may be arbitrary shapes.

[0018]

[Effect of the invention] It goes up and down over the entire circumference of the upper part of the heat radiation part.
The cylindrical guide heater section is brought into close contact with the guide
The heater section extends over the entire periphery of the transpiration hole on the upper wall.
The close proximity makes it possible for the chemicals evaporating due to the heat rising airflow generated by the heating element to evacuate the inside of the radiator and guide heater.
Through the space between Ru can be directed to smooth the transpiration hole. Special
To, even if the inflow stronger crosswind transpiration holes from the outside, the heat radiating portion, guide the heater unit, since there is a gap between the respective transpiration holes, <br/> device by crosswind that transpired the drug flows into Inside the heat radiation part and guide heater part inside the main body
Flow into Takeno in addition to the part space can be completely eliminate.
In this way, by evaporating the evaporating agent toward the evaporating hole in the upper wall and evaporating to the outside of the device body, the agent can be completely prevented from staying inside or adhering to the device body,
The desired stable drug evaporation effect can be obtained.

In the radiating section and the guide heater section, when the transpirated drug is heated and rapidly cooled by contact with a cold wall or the like, the clotting of the drug and the adhesion of the drug occur. If the contact is made, the above-described adhesion phenomenon does not occur. Therefore, even if the medicine comes into contact with the heat radiating portion or the guide heater portion, the medicine does not adhere because the heat radiating portion and the guide heater portion are hot.

In addition, since the guide heater is provided between the heat radiating portion provided on the inner periphery of the heating element and the evaporation hole, the heating element is provided.
Without approaching itself near the transpiration hole in the upper wall ,
It is possible to prevent spillage of drugs into the device body,
As a result, it is possible to increase the spatial distance between the upper wall provided with the transpiration holes and the heating element, so that excessive heat rise in the upper wall of the apparatus main body is eliminated, and the user touches the vicinity of the upper wall of the apparatus main body. Even if it does not burn, it can be set as the structure.

Further, since the evaporated drug always passes through the internal space of the heat radiating portion and the guide heater portion , the structure of the heat radiating portion or the guide heater portion is changed, so that the drug evaporating passage in the apparatus main body can be arbitrarily adjusted to some extent. It is possible to design, and the diameter of the transpiration hole can be reduced to some extent, for example, it can be reduced to a size that does not allow the infant's finger to enter, eliminating accidents such as infants getting burned by sticking their fingers into the transpiration hole. Further, safety can be further improved.
