The present invention is a fumigation apparatus that is applied to sanitary pests in rooms and other limited spaces, for example, mosquitoes, flies, cockroaches, etc., or for sterilization, and incense in limited spaces. A fumigation apparatus of the type in which these processes are concentrated in a short time.

Conventionally, a method for intensively controlling hygiene pests in a short time is carried out by so-called smoking, which contains a drug and a combustion agent, and intensively increases the drug in a short time by the heat and combustion of the combustion agent. Known in remedies, it has the following drawbacks: In other words, it is necessary to use a combustion agent that generates toxic fumes in order to increase the amount of chemicals instantaneously, and there is a risk of irritating odor or human body caused by the combustion of this combustion agent and the risk of fire due to the combustion of this combustion agent. And the like, there is a problem in terms of safety and simplicity of use. Further, there is a drawback that the drug is decomposed by the heat of combustion, and the effective volatilization rate is lowered, and further, the drug efficacy is lowered and the economic loss is caused.

The present invention has been made for the purpose of eliminating all the above-mentioned drawbacks, that is, the present invention provides a fumigation agent containing a foaming agent in an airtight external container for accommodating exothermic substances that come into contact with water. The open type container for accommodating is accommodated using at least one part of the bottom wall and the side wall of this inner container as a partition, and the absorption hole is formed in at least one of the lower part of the bottom wall or side wall of the said outer container. It is related with a fumigation apparatus.

The present invention has a structure as described above, in use, when the lower part of the outer container is immersed in water, water is sucked into the outer container at the absorption hole in the bottom wall and / or the lower side wall of the outer container, and the sucked water is inside Contact with and generate heat.

As a result, the blowing agent-containing pharmaceutical agent in the inner container is heated through the bottom wall and the side wall by the above-mentioned heat generation, and when it reaches the decomposition temperature of the blowing agent by this heating, the foaming agent is formed and the evaporation of the pharmaceutical ingredient simultaneously with the foaming. This occurs, and the drug component is concentrated intensively in a short time. By filling this evaporated chemical | medical agent in the limited space, the predetermined process according to drug efficacy can be performed. In addition, the supply of water to the exothermic material may be such that water is supplied to the exothermic material through a layer having a property of permeating water, for example, a water permeable layer. The method of preparing, etc. is arbitrary.

Since the present invention employs the above-mentioned evaporation means, the evaporation of the drug does not involve combustion or smoke, and it is excellent in safety and simplicity in use, and hardly decomposes the drug. Problems, such as a decrease in volatilization rate, are also solved, and it has the characteristic that the effect of a chemical | medical agent can be exhibited with high efficiency.

On the other hand, the outer container filled with the heating material is a sealed system in the bottom wall or the lower side of the side wall during use, so that it becomes a complete sealing system and leaks gas that may occur during heat loss and heat generation. Can be prevented.

In addition, when the foaming agent-containing chemical is heated, the bottom wall and the sidewall of the inner container act as a heating heat transfer surface, and a wide heat transfer surface is obtained, and thus the above-mentioned chemical agent can be heated efficiently.

In the present invention, the outer container is sealed, and the inner container is accommodated in the outer container using at least a portion of the bottom wall and the sidewall of the inner container as a partition wall. The number of containers of the container for the external container is arbitrary, and there may be one or more. When accommodating only one container for an external container, it is preferable to provide concentrically. However, in some cases, the container may be provided either sideways, left or right of the external container, or at another suitable position. You may also do it. The bottom wall of this inner container can be made into the pole surface of cross-sectional pole as needed, and the side wall may be inclined.

Unevenness may be formed on the outer surfaces of the bottom wall and the side wall in order to enlarge the surface area. The inside of the inner container may be split vertically and divided into separate chambers to accommodate different kinds of drugs. The upper part of this container has an opening, and the opening can be provided with a protective cover having a ventilation hole.

An absorption hole for supplying water into the outer container is formed in the lower wall or the side wall of the outer container. It is preferable to form this absorption hole in a dispersed phase on the front surface of the bottom wall and the entire peripheral surface of the lower side wall.

The absorbing hole of the outer container and the upper opening portion of the inner container can be coated or covered with a seal to stabilize the state of accommodating the drug and the exothermic material and to prevent moisture absorption.
