In the heating device of the present invention, the reaction between the heat-generating agent and water is appropriately adjusted, thereby suppressing the generation of excessive water vapor caused by rapid heating.

Although embodiments of the present invention will be described with reference to the drawings, the present invention is not limited only to those shown in the drawings.

The heating device of the present invention includes a bottomed cylindrical body, a fixture, a water-permeable sheet, and a heat-generating agent.

The bottomed cylindrical body 11 is a container having an opening at the top as shown in FIG. 4 . The overall shape of the bottomed cylindrical body can be a cylinder or a angular cylinder. From the perspective of equal heat transfer, a cylinder is ideal. The bottom of the bottomed cylindrical body is not limited to the shape shown in Figure 4, and may also be a flat bottom, a round bottom, a petaloid bottom, etc. The bottomed cylindrical body is ideally made of a material with high thermal conductivity. Examples include: steel (eg stainless steel), aluminum, aluminum alloy, copper, copper alloy, etc. As shown in FIG. 5 , the heat generating agent 14 is accommodated in the cavity of the bottomed cylindrical body. The bottomed cylindrical body shown in Figure 4 is provided with a flange (or flange) on the top edge. The flange 5 can be used as a hanging support when the bottomed cylindrical body is inserted into a predetermined hole of the inner cover described later.

The exothermic agent 14 is not particularly limited as long as it generates heat by reaction with water. Examples of the exothermic agent include calcium oxide, magnesium oxide, aluminum chloride, calcium chloride, iron oxide, and the like. Among these, calcium oxide is ideal. Calcium oxide (quicklime) is obtained through lime calcining method to obtain soft burnt lime and hard burnt lime. Hard burnt lime reacts with water more slowly than soft burnt lime. When aiming at a heating pattern that suppresses the initial calorific value and then slowly generates heat; when mixed with soft burnt lime to adjust the reaction speed, hard burnt lime is suitable. Soft burnt lime reacts quickly with water. In the present invention, it is preferable to use a heat-generating agent containing soft burnt lime as a main component.

Although the exothermic agent is not particularly limited by its shape, it is preferable to form particles from the viewpoint of ease of contact with water. The ideal particle size is 1 to 5 mm when screened. The amount of the exothermic agent used is not particularly limited as long as it can generate the heat required for smoking, but is ideally 5 to 50 g. The apparent volume of the exothermic agent is preferably 1/3 to 2/3 of the volume of the bottomed cylindrical body. Therefore, the size of the bottomed cylindrical body can be appropriately set according to the usage amount, size, shape, etc. of the exothermic agent.

The water-permeable sheet 13 is not particularly limited as long as it can pass water. Examples include woven fabrics, non-woven fabrics, etc. The material of the water-permeable sheet is not particularly limited as long as it can withstand the heat generated by the exothermic agent. As for the material of the water-permeable sheet, examples include: polyethylene, polypropylene, polyester, rayon, pulp, cotton, etc. Nonwoven fabrics are not limited by their manufacturing methods, such as spunbonding, meltblown, thermal bonding, chemical bonding, water needling, needle punching, etc. The ideal thickness of the water-permeable sheet is 0.1~1.0mm. The size of the water-permeable sheet is not particularly limited as long as it can cover the heating agent contained in the bottomed cylindrical body. For example, as shown in FIG. 6 , the water-permeable sheet may have a size that is in contact with the inner surface of the cylindrical wall of the bottomed cylindrical body in which the heat-generating agent is accommodated.

The fixture 12 has a flat plate portion. The fixture shown in FIGS. 2 and 3 further has a side wall portion 7 rising from the outer edge of the flat plate portion. Although not shown in the figures, the fixture may have a flat plate portion and a gasket fitted to the outer edge of the flat plate portion. The flat plate portion is provided with at least one hole (water passage hole) 6 through which it can pass. Furthermore, at least one partition portion 8 is provided in which the flat plate portion protrudes toward the cavity of the covered bottomed cylindrical body. The shape, structure, etc. of the spacer portion are not particularly limited as long as they can prevent the water-permeable sheet 13 from being in close contact with the flat plate portion and blocking the water holes. In the fixture shown in FIG. 3 , at least one edge of the water passage hole 6 protrudes toward the cavity of the covered bottomed cylindrical body to form a partition 8 . Such a spacer portion 8 can be in contact with the water-permeable sheet 13 and can prevent the water-permeable sheet and the flat plate portion from clogging the hole. Thereby, water can flow from the hole in the flat plate part of the fixture through the water-permeable sheet into the cavity where the heat-generating agent is accommodated without stagnation.

The flat plate part has a size (Fig. 7) that can fall into the cavity of the bottomed cylindrical body and cover the bottomed cylindrical body. The outer edge of the flat plate portion of the fixture is preferably designed to have a size such that the side wall portion abuts the inner surface of the cylindrical wall of the bottomed cylindrical body as shown in FIG. 2 . The fixture designed in this way can suppress the shaking of the heat-generating agent in the cavity of the bottomed cylindrical body. The material of the fixture is not particularly limited as long as it can withstand the heat generated by the exothermic agent. Examples include metal materials such as steel (such as stainless steel), aluminum, aluminum alloys, copper, and copper alloys; organic materials such as paper and plastic.

The opening at the top of the bottomed cylindrical body can also be covered with a film or the like if necessary. As for the film used as a cover, a moisture-proof sheet is ideal. By covering the opening at the top of the bottomed cylindrical body with a film, it is possible to prevent deterioration of the exothermic agent due to moisture absorption from outside air, reaction with smoke agent, etc. Examples of films used as lids include synthetic resin films, laminated aluminum films, and the like. The thickness of the film used as a cover is preferably 10 to 100 μm.

The smoking device 30 of the present invention includes the heating device 10 of the present invention, a smoking agent 32, and a cylindrical body container 31.

In the smoking device of the present invention, the smoking agent 32 and the heating device 10 are sealed in the cylindrical body container 31 . The overall shape of the cylindrical body container can be a cylinder or a angular cylinder. From the perspective of equal heat transfer, a cylinder is ideal. The material of the cylindrical body container is not particularly limited as long as it can withstand the heat applied by the heating device. Examples include metal materials such as steel (such as stainless steel), aluminum, aluminum alloys, copper, and copper alloys; organic materials such as paper and plastic. The top surface of the cylindrical container can also be sealed with a lid that can be cut with a can opener. However, it is ideal to seal it with a pull-tab type easy-open can lid, a pull-tab type easy-open can lid, or the like. An easy-open can with a full-open lid as shown in Figure 14 is ideal.

Fumigants are substances that become smoke by heating. Smoke is composed of solid and liquid particles dispersed in a colloidal state in the gas. The size of particles in smoke is about 0.1 to 10 μm. Fumigants may also contain pharmaceutical agents. Examples of pharmaceutical agents include pest removers such as insecticides, repellents, attractants, and insect growth regulators; microorganism removers such as antibacterial agents, bactericides, and fungicides; fragrances, and deodorants. wait.

Use fungicides; environmental sanitation fungicides such as thiabendazole (TBZ), thiabendazole, 3-iodo-2-propynyl-butylcarbamate (IPBC), IF-1000, etc.; silver ions, etc. These medicines can be used individually by 1 type or in combination of 2 or more types appropriately. The amount of the agent in the fumigant is, for example, 0.1 to 50% by mass.

The smoke agent may also contain additives such as exothermic base agent, exothermic auxiliary agent, stabilizing agent, binding agent, excipient, fragrance, pigment, etc. as needed. Examples of the exothermic base include combustion agents, organic foaming agents, and the like. Examples of the combustion agent include mixtures of oxidizing agents such as potassium chlorate, potassium perchlorate, and potassium nitrate and combustible substances such as starch, lactose, and cellulose, and nitrocellulose. As an organic foaming agent, one that generates carbonic acid gas, nitrogen gas, etc. is preferably used. Examples of organic foaming agents include: azodimethylamide, p,p'-oxybis(benzenesulfonylhydrazine), N,N-dinitrosopentamethylenetetramine, azobis Isobutyronitrile etc. Examples of the heating aid include zinc stearate, magnesium stearate, zinc oxide, magnesium oxide, zinc carbonate, calcium carbonate, urea, and the like. Examples of stabilizers include: sorbitan fatty acid ester, dibutylhydroxytoluene, butylhydroxyanisole, gallic acid, epoxy compounds (epoxidized soybean oil, epoxidized linseed oil, etc.) )wait. Examples of the binding agent include: methyl cellulose, ethyl cellulose, carboxymethyl cellulose, hydroxypropyl cellulose, hydroxypropyl cellulose, starch, dextrin, hydroxypropyl starch, gelatin , polyvinyl alcohol, polyvinyl acetate, polyvinylpyrrolidone, sodium polyacrylate, etc. Examples of excipients include clay (hydrated aluminum silicate), talc, diatomaceous earth, kaolin, bentonite, white carbon, calcium carbonate, and the like.

The amount of the fumigant filled in the cylindrical body container can be appropriately determined taking into account the scale of the space to be smoked, the type and amount of chemicals in the fumigant, and the like. For example: for a house of 10 to 13m ² (6 to 8 tatami mats), it is about 10 to 12.5g, for a facility of 30 to 250m ² , gardening equipment, etc., it is about 10 to 100g, and for a warehouse of 40 to 900m ² , it is 120 ~600g or so.

Half of the fumigant is prepared into a solid preparation in the form of powder, granular, flake, etc. Solid preparations can be prepared using well-known manufacturing methods according to the intended dosage form. For example, when preparing a granular preparation, it can be produced by a well-known granulation manufacturing method such as extrusion granulation, compression granulation, stirring granulation, rolling granulation, and fluidized bed granulation.

The smoking device of the present invention may further have an inner cover 33 . The structure and shape of the inner cover can be appropriately designed according to the purpose. For example, an inner cover as shown in Figure 8 can be used. The inner cover is used to fix the heating device 10 enclosed in the cylindrical body container so that it does not fly out due to sudden boiling of the smoke agent, and to adjust the discharge amount of the smoke quality.

The inner cover 33 shown in FIG. 8 is composed of an upper inner cover 33a shown in FIG. 9 and a lower inner cover 33b shown in FIG. 10 . The upper inner cover and the lower inner cover are shallow-bottomed cylindrical bodies with slightly different diameters and are formed into a nested shape. The inner cover shown in FIG. 8 is formed in a nested shape so that the bottom surface of the upper inner cover becomes the top surface of the inner cover, and the bottom surface of the lower inner cover becomes the bottom surface of the inner cover. The lower inner cover is provided with a hole (fitting hole) 35 for inserting the heating device in the center of its bottom surface. In addition, the lower inner cover is provided with at least one hole (smoke hole) 37 for allowing the smoke to flow out on the peripheral side close to the bottom surface. On the other hand, the upper inner cover is provided with a hole (water injection hole) 36 in the center of its bottom surface (the top surface of the inner cover) for allowing water to flow into the heating device. The vicinity of the water injection hole is inclined and recessed so that the injected water flows toward the hole. Furthermore, the upper inner cover is provided with at least one hole (smoke hole) 37 on the peripheral side close to the bottom surface for letting the smoke coming through the smoke hole of the lower inner cover flow out. The smoke holes provided in the lower inner cover and the smoke holes provided in the upper inner cover may or may not correspond to each other when the lower inner cover and the upper inner cover are overlapped in a nested manner.

The smoking device of the present invention may further include a container (water bag) containing a predetermined amount of water in a cylindrical body container. For example, the water bag can be placed in a recess near the water filling hole 36 of the upper inner cover 33a.

The smoking device 30 shown in Figure 15 further has a heat conductive plate. The shape and structure of the heat conductive plate are not particularly limited as long as the heat from the heating device can be uniformly transferred to the entire cylindrical body container. The heat conductive plate provided in the smoking device shown in Fig. 15 is formed by a convex portion 34a and a flat portion 34b that are in contact with the bottom of the heating device. The heat from the heating device is heat-conducted to the flat-plate part through the convex part, and the heat is transferred from the flat-plate part to the lower part of the smoke agent.

The smoking device of the present invention spits out smoke when water is poured into the heating appliance 10 from the water injection hole 36 after the top surface of the cylindrical body container is opened. Also, when covering the top opening of the bottomed cylindrical body of the heating device with a film, peel off the film or poke holes in the film with a pointed object before filling it with water. Polyols such as ethylene glycol and oxidizing agents such as potassium permanganate may be dissolved in the injected water. By adding water, the concentration of the color of the smoke produced, the amount of the smoke produced, and the duration of the smoke generation (smoke duration) are also controlled. Water can be measured with a measuring dropper, a measuring cup, etc. and poured into a predetermined amount, or a container (water bag) containing a predetermined amount of water can be poured into a container (water bag) containing a predetermined amount of water by perforating a needle, a knife, or the like. Furthermore, a mechanism for opening the lid of the easy-open can on the top surface of the cylindrical body container and simultaneously perforating the water bag may be provided to inject water into the heating device 10 .
