[2] A smoking device characterized by comprising: the heating device described in [1], a fumigant, and a cylindrical body container, in which the fumigant and the heating device are enclosed. [Effects of the invention]

In the heating device of the present invention, the reaction between the exothermic agent and water is appropriately adjusted to suppress the generation of transient water vapor caused by rapid heating.

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

The heating device of the present invention has a bottomed cylindrical body, a fixture, a water-permeable sheet, and a heating 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 an angular cylinder. From the viewpoint of equal heat transfer, the cylinder is ideal. The bottom of the bottomed cylindrical body is not limited to the shape shown in FIG. 4, and may be a flat bottom, a round bottom, a petaloid bottom, or the like. The bottomed cylindrical body is ideally formed of a material with high thermal conductivity. For example, steel (for example, stainless steel), aluminum, aluminum alloy, copper, copper alloy, etc. can be mentioned. As shown in FIG. 5, the heat generating agent 14 is accommodated in the cavity of a bottomed cylindrical body. The bottomed cylindrical body shown in Figure 4 is provided with flanges (or also called flanges) 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 exothermic agents include calcium oxide, magnesium oxide, aluminum chloride, calcium chloride, and iron oxide. Among these, calcium oxide is ideal. Calcium oxide (quick lime) is obtained by calcining soft lime and hard lime. Hard burnt lime reacts more slowly with water than soft burnt lime. When it points to a heating mode that suppresses the initial heat generation and then slowly generates heat; when mixed with soft burnt lime to adjust the reaction rate, hard burnt lime is suitable. The reaction speed of soft burnt lime with water is fast. In the present invention, it is preferable to use an exothermic 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 easy contact with water. It is ideal that the size of the particles is sieved to 1 to 5 mm. The amount of the heat-generating agent used is not particularly limited as long as the amount of heat required for fumigation can be generated, but it is preferably 5 to 50 g. It is desirable that the apparent volume of the exothermic agent is 1/3 to 2/3 relative to the volume of the bottomed cylindrical body. Therefore, the size of the bottomed cylindrical body can be appropriately set according to the amount, size, shape, and the like of the exothermic agent.

The water-permeable sheet 13 is not particularly limited as long as it passes water. For example, woven fabrics, non-woven fabrics, etc. can be cited. The material of the water-permeable sheet is not particularly limited as long as it can withstand the heat from the exothermic agent. As for the material of the water-permeable sheet, for example, polyethylene, polypropylene, polyester, rayon, pulp, cotton, etc. can be mentioned. The non-woven fabric is not limited by its manufacturing method, for example: spunbonding, meltblown, thermal bonding, chemical bonding, water needle, needle punching, etc. The thickness of the permeable sheet is desirably 0.1 to 1.0 mm. The size of the water-permeable sheet is not particularly limited as long as it can cover the exothermic agent contained in the bottomed cylindrical body. For example, as shown in FIG. 6, the water-permeable sheet may have a size such that it abuts on the inner surface of the cylindrical wall of the bottomed cylindrical body in which the exothermic agent is accommodated.

The fixture 12 has a flat plate part. The fixture shown in FIG. 2 and FIG. 3 further has the side wall part 7 standing up from the outer edge of a flat part. Although not shown, the fixture may have a flat plate part and a washer inserted into the outer edge of the flat plate part. At least one hole (water passing hole) 6 that can pass through is provided in the flat plate portion. In addition, at least one partition portion 8 protruding into the cavity of the aforementioned bottomed cylindrical body covered by the flat portion is provided. As long as the partition can prevent the water-permeable sheet 13 and the flat plate from coming into close contact with each other to block the water-passing hole, there is no particular limitation in shape, structure, and the like. In the fixture shown in FIG. 3, at least one edge of the aforementioned water-passing hole 6 protrudes into the hollow of the covered bottomed cylindrical body to form a partition 8. Such a partition 8 can abut on the water-permeable sheet 13 and can prevent the water-permeable sheet and the flat portion from sticking to clogging the hole. Thereby, water can flow from the hole of the flat plate portion of the fixture through the water-permeable sheet without stagnation and fall into the cavity of the heat-generating agent.

The flat part has a size that falls into the hollow of the bottomed cylindrical body and can cover the bottomed cylindrical body (Figure 7). It is ideal for the fixture to design the outer edge of the flat plate part such that the side wall of the fixture shown in FIG. 2 abuts against the inner surface of the cylindrical wall of the bottomed cylindrical body. The fixture designed in this way can prevent the heating agent from shaking 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 heating agent. For example, metal materials such as steel (for example, stainless steel), aluminum, aluminum alloy, copper, copper alloy, etc.; organic materials such as paper and plastics, and the like.

The opening at the top of the bottomed cylindrical body can also be covered with a film or the like as needed. 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 the deterioration of the exothermic agent due to moisture absorption from outside air, reaction with fumigant, etc. Examples of films used as lids include synthetic resin films, laminated aluminum films, and the like. The thickness of the film used as the cover is preferably 10-100 μm.

The smoking device 30 of the present invention is one having the heating device 10 of the present invention, the fumigant 32, and the cylindrical body container 31.

In the smoking device of the present invention, the smoking agent 32 and the heating device 10 are enclosed in the cylindrical main body container 31. The overall shape of the cylindrical body container can be a cylinder or an angular cylinder. From the viewpoint of equal heat transfer, the 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. For example, metal materials such as steel (for example, stainless steel), aluminum, aluminum alloy, copper, copper alloy, etc.; organic materials such as paper and plastics, and the like. Although the top surface of the cylindrical body container may be sealed with a lid that can be cut with a can opener, it is desirable to seal it with a pull-tab type easy-opening lid, a pull-tab type easy-opening lid, or the like. The easy-opening can is ideally a full-open lid as shown in Figure 14.

Fumigant is a substance that becomes aerosol by heating. The aerosol is solid and liquid particles dispersed in a colloidal state in a gas. The size of the particles in the aerosol is about 0.1-10 μm. Fumigants may also contain medicaments. Examples of medicaments include: insecticides, insect repellents, attractants, insect growth regulators, and other pest removal agents; antibacterial agents, fungicides, antifungal agents, and other microorganism removers; fragrances, deodorants Wait.

As for the pest removal agent, for example, permethrin, arenine, lenfenine, cyfenac, puyalenin, bifenin, profluthrin, fenvalin, phenothrin, fenvalin Pyrethroid-based agents such as Pyrethroid, Fempnin, Efennine, etc.; Organophosphorus-based agents such as Diclofenac, Dicloxone (DDVP), Trisone, Prothiosone, Vitex, etc.; Carbamate-based medicaments such as butyl chlorpyrifos (BPMC); bisbenzyl urea-based medicaments such as disulfuron, ceflon, and diflufenuron; sulfonate, idamide, Neonicotinoids such as Sasuan; Diamide-based drugs such as Fluoxan and Kambo; Electronic transmission type I inhibitors such as Defenex and Tefenex. For microbial removal agents, for example, there are pesticides such as Saifuza, Saifofenac, Tetrachloroisophenylene (TPN), Eproton, Metopeline, Promethazine, Tritaifen, Milidan, etc. Use fungicides; thiabendazole (TBZ), decay, 3-iodo-2-propynyl-butyl carbamate (IPBC), IF-1000 and other environmental sanitation fungicides; silver ions, etc. These drugs can be used singly or in appropriate combinations of two or more. The amount of the drug in the fumigant is, for example, 0.1-50% by mass.

Fumigants may also contain additives such as exothermic bases, exothermic assistants, stabilizers, binders, excipients, flavors, and pigments as needed. Examples of exothermic bases include combustion agents and organic foaming agents. Examples of combustion agents 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 the organic blowing agent, it is desirable to use one that generates carbon dioxide gas, nitrogen gas, or the like. For organic blowing agents, for example, azodimethamide, p,p'-oxybis(benzenesulfonamide), N,N-dinitrosopentamethylenetetramine, azobis Isobutyronitrile and so on. Examples of heat-generating aids include zinc stearate, magnesium stearate, zinc oxide, magnesium oxide, zinc carbonate, calcium carbonate, and urea. Examples of stabilizers include sorbitan fatty acid esters, dibutylhydroxytoluene, butylhydroxyanisole, gallic acid, epoxy compounds (epoxidized soybean oil, epoxidized linseed oil, etc.) )Wait. Examples of binding agents include methylated cellulose, ethyl cellulose, carboxymethyl cellulose, hydroxypropylated cellulose, hydroxypropyl cellulose, starch, dextrin, hydroxypropyl starch, gelatin , Polyvinyl alcohol, polyvinyl acetate, polyvinylpyrrolidone, sodium polyacrylate, etc. Examples of excipients include clay (hydrous aluminum silicate), talc, scopolamine, kaolin, bentonite, white carbon, calcium carbonate, and the like.

The amount of fumigant filled in the cylindrical main body container can be appropriately determined in consideration of the size of the space to be fumigated, the type and amount of medicine in the fumigant, and the like. For example: 10～12.5g for houses of 10～13m ² (6～8 tatami mats), 10～100g for facilities and gardening equipment of 30～250m ² and 120 for warehouses of 40～900m ² ~ About 600g.

Half of the fumigant is prepared into a solid preparation in the shape of powder, granules, flakes, etc. The solid preparation is in accordance with the intended dosage form and can be prepared using a well-known manufacturing method. For example, when a granular formulation is prepared, it can be produced by a known granulated production method such as an extrusion granulation method, a compression granulation method, a stirring granulation method, a rotation granulation method, and a fluidized bed granulation method.

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 Fig. 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 the sudden boiling of the fumigant, and to adjust the discharge amount of the smoke.

The inner cover 33 shown in FIG. 8 is composed of the upper inner cover 33a shown in FIG. 9 and the lower inner cover 33b shown in FIG. 10. The upper inner cover and the lower inner cover are formed into nested cylindrical bodies with a shallow depth and slightly different diameters. In the inner cover shown in FIG. 8, 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 to form a nested overlap. The lower inner cover is provided with a hole (fitting hole) 35 for inserting the heating device in the center of the bottom surface. In addition, the lower inner cover is provided with at least one hole (smoke hole) 37 for letting smoke 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 (top surface of the inner cover) to allow water to flow into the heating device. The vicinity of the water injection hole is inclined and recessed to allow the injected water to flow 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 of the lower inner cover for letting the smoke coming from the smoke hole of the lower inner cover flow out. The smoking holes provided in the lower inner cover and the smoking 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 shape.

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

The smoking device 30 shown in FIG. 15 further has a heat conductive plate. As long as the heat conduction plate can uniformly transfer heat from the heating device to the entire cylindrical body container, its shape and structure are not particularly limited. The heat conduction plate provided in the smoking device shown in FIG. 15 is formed by a convex portion 34a and a flat plate portion 34b that abut on the bottom of the heating device. The heat from the heating device is transferred to the flat part through the convex part, and the heat is transferred from the flat part to the lower part of the fumigant.

In the smoking device of the present invention, after opening the top surface of the cylindrical body container, when water is injected into the heating device 10 from the water injection hole 36, the smoke is discharged. In addition, when covering the opening at the top of the bottomed cylindrical body of the heating device with a film, peel off the film or poke a hole in the film with a pointed object before pouring water. Oxidizing agents such as polyols such as ethylene glycol and potassium permanganate can also be dissolved in the injected water. With the addition of water, the concentration of the color of the smoke produced, the amount of smoke produced, and the duration of smoke production (smoke duration) are also controlled. Water can also be measured with a measuring dropper, a measuring cup, etc. to fill a predetermined amount, or a needle, knife, etc. can be used to perforate a container (water bag) containing a predetermined amount of water. In addition, a mechanism for opening the lid of the easy-opening can on the top surface of the cylindrical body container and perforating the water bag may be provided to inject water into the heating device 10.
