Detailed Description

The embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the contents depicted in the drawings.

The heating device of the present invention has a bottomed cylindrical body, a fixing member, 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 may be a cylinder or a square cylinder. From the viewpoint of uniform heat transfer, a cylinder is preferable. 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 petal bottom, or the like. The bottomed cylindrical body is preferably formed of a material having high thermal conductivity. Examples thereof include steel (e.g., stainless steel), aluminum alloy, copper, and copper alloy. As shown in fig. 5, the heat generating agent 14 is contained in the hollow of the bottomed cylindrical body. The bottomed cylinder shown in fig. 4 is provided with a flange (or also referred to as a blade) at a portion of the edge of the top. The flange 5 is capable of supporting a bottomed cylindrical body in a suspended manner when fitted into a predetermined hole of an inner lid described later.

The heat generating agent 14 is not particularly limited as long as it generates heat by a reaction with water. Examples of the heat generating agent include calcium oxide, magnesium oxide, aluminum chloride, calcium chloride, and iron oxide. Among them, calcium oxide is preferable. Calcium oxide (quicklime) soft-burnt quicklime and hard-burnt quicklime can be obtained according to the method of burning lime. Hard burnt quicklime reacts slower with water than soft burnt quicklime. In the case of directing to a heat generation mode in which the initial heat generation amount is suppressed and then the heat is slowly generated, or in the case of mixing with soft burnt quicklime and adjusting the reaction rate, hard burnt quicklime is preferable. The reaction speed of the soft burnt quicklime and water is high. In the present invention, it is preferable to use a heat generating agent containing soft burnt quicklime as a main component.

The heat generating agent is not particularly limited in terms of its shape, but from the viewpoint of ease of contact with water, a heat generating agent that forms particles is preferred. When the screening is performed, the size of the particles is preferably 1mm to 5mm. The amount of the heat generating agent to be used is not particularly limited as long as it can generate heat necessary for smoking, and is preferably 5g to 50g. The apparent volume of the heat generating agent is preferably 1/3 to 2/3 of the volume of the bottomed cylindrical body. Thus, the size of the bottomed tubular body can be set as appropriate in accordance with the amount, size, shape, and the like of the heat generating agent used.

The water-permeable sheet 13 is not particularly limited as long as it is a member that allows water to pass therethrough. Examples thereof include woven fabric and nonwoven fabric. The material of the water-permeable sheet is not particularly limited as long as it can withstand the heat generated by the heat-generating agent. Examples of the material of the water permeable sheet include polyethylene, polypropylene, polyester, rayon, pulp, and cotton. The nonwoven fabric is not limited by the production method, and examples thereof include spunbond, meltblown, thermal bond, chemical bond, spunlace, and needle punch. The thickness of the water-permeable sheet is preferably 0.1mm to 1.0mm. The water-permeable sheet is not particularly limited as long as it is of a size that can cover the heat generating agent contained in the bottomed tubular body. For example, as shown in fig. 6, the water-permeable sheet may have a size to be in contact with the inner surface of the cylindrical wall of the bottomed cylindrical body in which the heat generating agent is stored.

The fixed member 12 has a flat plate portion. The anchor shown in fig. 2 and 3 further has a side wall portion 7 rising from the outer edge of the flat plate portion. Further, although not shown, the anchor may have a flat plate portion and a washer fitted into an outer edge of the flat plate portion.

The flat plate portion is provided with at least one hole (water passage hole) 6 through which water can pass. At least one spacer 8 is provided on the flat plate portion so as to protrude into the hollow of the closed bottomed cylindrical body. The spacer is not particularly limited in terms of shape, structure, and the like, as long as it can prevent the water permeable sheet 13 from being closely attached to the flat plate portion to block the water passage holes. In the fixture shown in fig. 3, at least one edge of the water passage hole 6 protrudes into the hollow of the closed bottomed cylindrical body to form a spacer 8. Such a spacer 8 can abut against the water-permeable sheet 13, and can prevent the water-permeable sheet from being closely attached to the flat plate portion to block the hole. Thus, water can flow down from the holes of the flat plate portion of the fixing member to the cavity containing the heat generating agent via the water permeable sheet without being retained.

The flat plate portion has a size capable of being dropped into the cavity of the bottomed cylindrical body to cover the bottomed cylindrical body (fig. 7). Preferably, the fixing member is designed such that the outer edge of the flat plate portion is formed in such a size that the side wall portion abuts against the inner surface of the cylindrical wall of the bottomed cylindrical body in the fixing member shown in fig. 2. The fixture thus designed can suppress the heat generating agent from shaking in the hollow space of the bottomed tubular body.

The material of the fixing member is not particularly limited as long as it can withstand the heat generated by the heat generating agent. Examples thereof include metal materials such as steel (e.g., stainless steel), aluminum alloy, copper, and copper alloy, and organic materials such as paper and plastic.

The opening at the top of the bottomed cylindrical body may be covered with a film or the like as necessary. As the film used for the cover, a moisture-proof sheet is preferable. By covering the opening at the top of the bottomed tubular body with a film, deterioration of the heat generating agent due to moisture absorption from outside air, reaction with a fumigant, or the like can be prevented. Examples of the film used for the cap include a synthetic resin film, an aluminum film formed by lamination, and the like. The thickness of the film used for the cap is preferably 10 μm 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 main 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 main body container 31. The cylindrical body container may have an overall shape of a cylinder or a square cylinder. From the viewpoint of uniform heat transfer, a cylinder is preferable. The material of the cylindrical main body container is not particularly limited as long as it can withstand heat applied by a heating tool. Examples thereof include metal materials such as steel (e.g., stainless steel), aluminum alloy, copper, and copper alloy, and organic materials such as paper and plastic. The top surface of the tubular body container may be sealed with a lid that can be cut by a can opener, but is preferably sealed with a pull-tab type easy-open-end lid, a lid that retains a pull-tab type easy-open-end, or the like. The easy open end is preferably a fully open end as shown in figure 14.

The fumigant is heated to become a smoke substance. Aerosol is a substance in which solid or liquid particles are dispersed in a gas and are in a colloidal state. The size of the particles in the aerosol is about 0.1-10 μm.

The fumigant may also contain a medicinal agent. Examples of the chemical include an insecticide, a repellent, an attractant, a pest repellent such as an insect growth regulator, an antimicrobial agent, a microbial scavenger such as a bactericide and a fungicide, a fragrance, a deodorant, and the like.

Examples of the pest repellent include pyrethroid chemicals such as permethrin, allethrin, resmethrin, fenpropathrin, prallethrin, bifenthrin, proffluthrin, tau-fluvalinate, phenothrin, fenvalerate, fenpropathrin, and ethofenprox; organophosphorus agents such as fenitrothion, dichlorvos (DDVP), diazinon, prothiofos, fenthion and the like; carbamate-based agents such as propoxur, dioxanone, and fenobucarb (BPMC); benzoylphenylurea-based agents such as diflubenzuron, chlorfluazuron, and bistrifluron; neonicotinoids such as acetamiprid, imidacloprid and thiamethoxam; diamide drugs such as fluorocarboxamide and chlorester; and electron transport type I inhibitors such as thiophenopyraline and tolylpyran line. Examples of the microbial control agent include agricultural chemical fungicides such as triflumizole, flufenamide, tetrachloroisophthalonitrile (TPN), iprodione, mepanipyrim, procymidone, triadimefon and mefenpyr; and disinfectants for environmental sanitation such as Thiabendazole (TBZ), fenbendazole, 3-iodo-2-propynyl butylcarbamate (IPBC), IF-1000, and silver ions. These agents may be used alone or in combination of two or more. The amount of the chemical in the fumigant is, for example, 0.1 to 50 mass%.

The smoking agent may contain additives such as a heat-generating base, a heat-generating auxiliary, a stabilizer, a binder, an excipient, a perfume, and a pigment, as required.

Examples of the heat-generating base include a combustion agent and an organic foaming agent. Examples of the combustion agent include oxidizing agents such as potassium chlorate, potassium perchlorate, and potassium nitrate, combustible material mixtures such as starch, lactose, and cellulose, and nitrocellulose. As the organic foaming agent, an organic foaming agent generating carbon dioxide gas, nitrogen gas, or the like is preferably used. Examples of the organic foaming agent include azodicarbonamide, p '-oxybis (benzenesulfonylhydrazide), N' -dinitrosopentamethylenetetramine, and azobisisobutyronitrile.

Examples of the heat-generating auxiliary agent include zinc stearate, magnesium stearate, zinc oxide, magnesium oxide, zinc carbonate, calcium carbonate, and urea.

Examples of the stabilizer include sorbitan fatty acid esters, dibutylhydroxytoluene, butylhydroxyanisole, propyl gallate, and epoxy compounds (epoxidized soybean oil, epoxidized linseed oil, and the like).

Examples of the binder include methyl cellulose, ethyl cellulose, carboxymethyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, starch, dextrin, hydroxypropyl starch, gelatin, polyvinyl alcohol, polyvinyl acetate, polyvinyl pyrrolidone, and sodium polyacrylate.

Examples of the excipient include clay (hydrous aluminum silicate), talc, diatomaceous earth, kaolin, bentonite, white carbon, calcium carbonate, and the like.

The amount of the fumigant to be loaded in the cylindrical main body container can be appropriately determined in consideration of the scale of the space to be fumigated, the type and amount of the chemical in the fumigant, and the like. For example, relative to 10m ² ～13m ² The room and the like of (6 to 8 tatami) can be about 10g to 12.5g, and 30m ² ～250m ² The amount of the organic solvent may be about 10g to 100g, and may be about 40m ² ～900m ² The amount of the inorganic filler (C) may be about 120g to 600 g.

The fumigant is generally formulated as a solid preparation in the form of powder, granules, tablets, etc. The solid preparation can be prepared by a known production method according to a desired dosage form. For example, in the case of a granular preparation, the granular preparation can be produced by a known method for producing a granulated product, such as an extrusion granulation method, a compression granulation method, a stirring granulation method, a rolling granulation method, or a fluidized bed granulation method.

The smoker device of the invention can also have an inner lid 33. The configuration and shape of the inner lid may be appropriately designed according to the purpose. For example, an inner lid as shown in fig. 8 can be used. The inner lid is used for fixing the heating device 10 sealed in the cylindrical main body container, preventing the smoke from flying out due to bumping, adjusting the amount of smoke emitted, and the like.

The inner lid 33 shown in fig. 8 is composed of an upper inner lid 33a shown in fig. 9 and a lower inner lid 33b shown in fig. 10. The upper inner lid and the lower inner lid are bottomed cylinders having slightly different calibers and a small depth so as to be nested. The inner lids shown in fig. 8 are nested and overlapped so that the bottom surface of the upper inner lid becomes the top surface of the inner lid and the bottom surface of the lower inner lid becomes the bottom surface of the inner lid.

The lower inner lid has a hole (fitting hole) 35 in the center of the bottom surface thereof for fitting a heating device. In addition, the lower inner lid is provided with at least one hole (smoking hole) 37 for letting out the aerosol on a side near the periphery of the bottom surface thereof.

On the other hand, the upper inner lid is provided with a hole (water injection hole) 36 for allowing water to flow into the heating device at the center of the bottom surface (top surface of the inner lid), and the vicinity of the water injection hole is recessed obliquely so that the injected water flows toward the hole. Further, the upper inner lid is provided with at least one hole (smoking hole) 37 for allowing smoke substances passing through the smoking holes of the lower inner lid to flow out, on a side near the periphery of the bottom surface of the upper inner lid.

When the lower inner lid and the upper inner lid are overlapped in a nested manner, the positions of the smoking holes provided in the lower inner lid and the smoking holes provided in the upper inner lid may or may not correspond to each other.

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

The smoker device 30 shown in figure 15 also has a thermally conductive plate. The heat transfer plate is not particularly limited in shape or structure as long as it can uniformly transfer heat from the heating device to the entire inside of the cylindrical main body container. The heat conduction plate provided in the smoking device shown in fig. 15 is composed of a convex portion 34a and a flat plate portion 34b which are in contact with the bottom of the heating device. The heat from the heating device is conducted to the flat plate portion through the convex portion, and is transferred from the flat plate portion to the lower portion of the fumigant.

The smoking device of the present invention ejects smoke when water is injected into the heating appliance 10 from the water injection hole 36 after the top surface of the cylindrical main body container is opened. Further, in the case of covering the opening of the top of the heater having the bottom cylindrical body with a film, the film is peeled off or perforated with a tool having a sharp end before water injection.

The injected water may be dissolved with a polyhydric alcohol such as ethylene glycol or an oxidizing agent such as potassium permanganate. By adding these to water, the color density of the smoke produced, the amount of smoke produced, and the time during which the smoke continues to be produced (smoke generation duration) may be controlled.

The water may be weighed by a measuring pipette, a measuring cup, or the like and injected in a predetermined amount, or may be injected by piercing a container (water bag) containing a predetermined amount of water with a needle, a cutter, or the like. In addition, the water may be injected into the heating device 10 by providing a mechanism for opening the easy-open lid on the top surface of the cylindrical body container and punching a hole in the water bag.
