Description

[Detailed description of the invention] This invention relates to a device that heats and evaporates pine impregnated with insecticides, fungicides, indoor air fresheners, deodorizers, etc. using combustion heat generated by catalytic reactions. .

A metal catalyst such as platinum or palladium is brought into contact with a volatile fuel such as alcohol in the device body, causing an oxidation reaction and combustion, and the heat of combustion is used to heat a heat sink. A device that evaporates insecticides, etc. in pine trees placed on a heat sink has a simpler structure than one that uses electric heat to evaporate, and since it does not require cords, it is easy to use and can be placed easily. It also has the advantage of not being subject to any restrictions.

However, the oxidation reaction tends to generate moisture, and this moisture often condenses on contact with the case body and accumulates at the bottom of the case body. Although this reaction water does not directly act on the catalyst, it damages the equipment body. If water gets on the catalyst member when it is turned over,
The drawback is that the catalytic function is temporarily lost until the water dries, and combustion is interrupted.

This invention was devised to eliminate the above-mentioned drawbacks caused by reaction water, and is an attempt to prevent the adverse effects of reaction water with an extremely simple structure.

In this invention for the above purpose, a device body is formed from a fuel case and a cover member provided at the upper opening of the fuel case and having a mat insertion hole in the center, and a heat dissipation plate is provided below the mat insertion hole. In a heating evaporation device in which a catalyst member and a catalyst member are stacked one on top of the other, a wall is provided inside the fuel case,
It is characterized by forming a water reservoir between the inner wall and the case circumferential wall.

This invention will be explained in detail below using illustrated examples. In the figure, reference numeral 1 denotes the main body of the apparatus, which is composed of a bottomed cylindrical fuel case 2 having an opening at the top, and a cover member 3 screwed onto the opening of the fuel case 2.

An opening 5 is formed in the center of the cover member 3 into which a rectangular mat 4 impregnated with insecticide, bactericide, indoor air freshener, deodorizer, etc. is inserted, and around the mat insertion opening 5 is provided with an air circulation port 6. Further, there is a stepped portion 7 on the inner peripheral side of the cover member 3, and a partition plate 9 that also serves as a support member for the catalyst member 8 is attached to the stepped portion 7. The inside of the device is divided vertically into a heating chamber 10 and a fuel chamber 11 by this partition plate 9, and a heat dissipation plate 12 on which the mat 4 is placed on the heating chamber side is located below the mat insertion opening 5. It is set up as follows.

Further, in the center of the partition plate 9, the catalyst member 8, which houses a metal catalyst incorporated in a lattice pattern, is vertically inserted and fixed in a rectangular metal frame with both ends open.

Inside the fuel case 3, a wall portion 13 of a required height is protruded along the case circumference, and a water reservoir portion 14 is formed between this inner wall portion 13 and the case wall circumference. A water-absorbing material 15 made of filter paper, cloth, cotton, etc. is applied inside the water reservoir.

In the device having the above structure, fuel 16 can be put into the fuel chamber 11. Further, the fuel vaporized in the fuel chamber 11 passes through the catalyst member 8 and passes through the heating chamber 1.
It begins to flow to the 0 side. At this time, an oxidation reaction occurs in contact with the catalyst, combustion gas is generated, and the heat sink 1
2 is heated, and the insecticide, etc. in Matsuto 4 evaporates.

Furthermore, on the fuel chamber 11 side, the water produced by the oxidation reaction remains in the form of water vapor, condenses when it comes into contact with the peripheral wall surface of the fuel case 2, and flows down into the water pool portion 14 formed between the fuel chamber 11 and the inner wall portion 13, and soaks into the water absorbent material 15.

As described above, this invention provides the internal wall part 14 of the fuel case 2, forms the water reservoir part 14 between the inner wall part 14 and the case peripheral wall, and condenses in the fuel chamber 11. Even if the reaction water is allowed to flow down into the water reservoir 14 and the apparatus main body 1 is turned over, the reaction water is prevented from splashing onto the catalyst member 8 by the inner wall 13, so that the reaction water does not function as a catalyst. can prevent temporary loss of It also has the advantage of being simple in structure, since it is only necessary to form a water reservoir by providing it in the wall of the fuel case.
