Description

[Detailed Description of the Invention] The present invention relates to a fumigation device which can be used either on the floor or in a wall-mounted manner.

More specifically, the present invention relates to a fumigation device that can be used in a wall-mounted type that indirectly heats and fumigates a fumigation agent containing a foaming agent.

Conventionally, as a method of intensively attacking sanitary pests in a short period of time,
Contains a chemical and a combustion agent, and uses the combustion heat and smoke of the combustion agent to intensively evaporate the chemical in a short period of time.

A method of extermination using a so-called smoke agent is known, but it has the following drawbacks.

In other words, in order to instantly evaporate a large amount of chemicals, it is necessary to use a combustion agent that generates highly toxic smoke, and the smoke produced by this combustion agent produces a pungent odor and is dangerous to the human body, as well as the risk of fire due to the combustion of the combustion agent. It is dangerous and has problems in terms of safety and ease of use.

Therefore, no fumigation device that can be hung on a wall or the like has ever been proposed.

The present invention has been made to eliminate all of the above-mentioned drawbacks of the conventional technology.In other words, the present invention has an inner container for containing a fumigation agent containing a foaming agent in an outer container for containing a pyrogen. , the inner container is accommodated with at least part of the bottom wall and side wall as a partition wall, the outer container is provided with a locking portion for the wall, pillar, etc. at an appropriate position on the outer peripheral wall, and the outer container further includes This relates to a fumigation device characterized in that it is provided with a means for performing heat generation operation of a pyrogenic substance while the fumigation device is fixed to a wall, pillar, etc.

The present invention has the above-described structure, and the exothermic substance contained in the outer container generates heat under appropriate conditions.

Due to this heat generation, the foaming agent-containing drug contained in the inner container
The inner container is heated using at least a portion of the bottom wall and side wall as a heating heat transfer surface.

When the heating reaches the decomposition temperature of the blowing agent,
At the same time as the foaming agent foams, evaporation of the drug occurs promoted by the foaming, and the drug is intensively evaporated in a short period of time.

A predetermined treatment can be performed by filling a limited space such as a room with the evaporated medicine.

Since this invention uses the above-mentioned transpiration method, the transpiration of the drug does not involve combustion or smoke generation, and it is safe and easy to use, and the thermal decomposition of the drug is almost non-existent. Since this does not occur, problems such as a decrease in effective volatilization rate caused by thermal decomposition can be solved, and the effect of the chemical can be demonstrated with high efficiency.In addition, it can be used by being fixed or hung on walls, etc., so it can be used in warehouses, ship bottoms, etc. Even if the ceiling is quite high, the transpiration agent can reach the ceiling sufficiently, and it is possible to effectively exterminate pests such as cockroaches hiding in the ceiling. , as it gradually descends while spreading from a high position to the surrounding area, the dispersibility increases, and the chance of contact with pests increases accordingly.Furthermore, due to the diffusion and descent from such a high place, it spreads from the floor. Even when the cargo is piled up high, the transpiration agent can be sufficiently penetrated into the space behind the cargo, and the pest extermination performance of this type of fumigation device as a whole can be significantly improved.

Furthermore, since the outer container is equipped with a means that allows the exothermic substance to generate heat while it is anchored to a wall, etc., there is no need for dangerous operations such as locking it to a wall, etc. after generating heat. It has the advantage of allowing fumigation operations to be carried out safely and easily.

In the present invention, as the fumigation agent, various agents conventionally used for purposes such as extermination of pests, sterilization, and fragrance can be used.

The following can be exemplified as representative drugs.
