FIELD OF THE INVENTION The present invention relates to heating fumes of drugs such as insecticides, fungicides, indoor fragrances and deodorants.

For example, devices such as electric mosquito insecticides that release the medicament from the mat in the form of smoke by heating the mat impregnated with a medicament, such as an insecticide, are known in the art. However, since these apparatuses use electricity as a heat source for heating the mat, it is inevitably complicated in their manufacture. In addition, the use of electricity requires these devices to have a power supply wire, which in turn has the disadvantage that the location of the device is limited to where the power is supplied.

It is very common to protect yourself from pest bites by burning mosquito coils in the open air.However, as long as mosquito coils burn, the fire must always be present at the tip of the mosquito coil. .

Liquefied vaporizers designed to operate in accordance with the principles of Pockel silver heaters are also known in the art. In this fume, the principle of the Pockel heater, in which a gasification fuel such as benzine is converted into a heat-containing vapor by combustion due to asbestos lumps impregnated with a catalyst such as platinum or palladium, is applied to the principle of pesticide fumigation. This principle can serve the purpose of maintaining heat, but is not suitable for the insecticide fumigator, which is absolutely necessary to maintain the correct temperature.

This prior method is consistent with the fact that (1) the platinum mass cannot perform a uniform catalytic action and (2) the oxygen supply cannot maintain sufficient uniformity to produce a uniform mixture of oxygen and fuel. The disadvantage is the inability to achieve the purpose of maintaining temperature.

It is an object of the present invention to eliminate the above-mentioned disadvantages contained in the preceding pharmaceutical heating steamer and to eliminate the risks associated with the use of embers.

The present invention uses the heat of reaction generated by contacting a volatile fuel such as alcohol or a liquefied petroleum gas such as liquefied petroleum gas or dimethyl ether with platinum or palladium catalyst in air. In addition, the present invention is not limited by the place of use because its production is simple and no wire for power connection is required.

In detail, the pharmaceutical heating fumigation (hereinafter referred to as the heating fumigation) of the present invention is a container for volatile fuel or liquefied gas fuel, a metal catalyst and a metal catalyst in which a proper space is maintained and placed above the container. It is characterized by having a heat radiation plate for heating and fumigation the drug by maintaining a certain space on the top. It is also characterized in that the case described above is equipped with a vent for supplying air and / or combustion gas.

In another embodiment, the present invention is a heating vaporizer is a container for liquefied gas filling in the case, a nozzle connected to the above-mentioned container through the valve, the metal catalyst positioned at a distance that the gas ejected from the nozzle can collide with the metal catalyst And a heat radiation plate used for heating fumigation of the chemical agent located close to the catalyst described above, and adjusting the opening and closing of the air supply and / or combustion gas discharge passage and the aforementioned valve in the case. It is characterized by including the apparatus.

The heating steam of the present invention forms a constant space between the fuel container and the metal catalyst to obtain a well-mixed mixture of fuel gas and oxygen, and in addition to fumigation of the metal catalyst and chemicals so that the reflux of the combustion gas can proceed effectively. By forming a constant space between the heat radiation plates, it is possible to obtain a uniform temperature which has not been achieved so far.

In a preferred embodiment of the present invention, it is also possible to fabricate a heat steamer such that the space formed on top of the fuel container and the space formed on top of the metal catalyst containing the heat radiation plate for the heat fumigation of the drug therein are separated from each other by the insulating plate.

The heat steamer may be manufactured so that the support for holding the metal catalyst in place and the heat radiation plate for heat fumigation of the medicine are connected to each other as the same metal body. In addition, the heating fume is a container in which the fuel container is capable of replenishing its contents, or the contents thereof can be transported, stored, or transported in a volatile solid fuel, volatile liquid fuel or liquefied gas fuel in the container. It can also be manufactured as a refillable container.

1 and 2 show one exemplary heat steamer of the present invention. In these figures, (1) shows a case body in the form of a blind tube (Blind trbe), the inside of which is divided into a fuel container (1b) and a mole storage tank (1c) by a cylindrical inner wall (1a). The outer wall 1d of the case body extends upwardly than the inner wall 1a described above.

Inside the upper end of the extension part of the outer wall 1d, a case part 1e was formed through the entire circumference so that the case lid could be fitted.

Reference numeral 2 denotes a case lid, which consists of a circular top plate 21 and a cylindrical side wall 27, the cross section of which has a completely "U" shape. The upper plate 21 has a rectangular opening 22 in the center thereof and an air exhaust pipe 23 in the outer edge of the opening 22. The opening 22 on the upper surface 22a of the top plate has a rectangular shape similar to and slightly larger than the insecticide mat 3 loaded in the heat steamer. In addition, the lower surface 22b of the upper plate has a rectangular shape similar to and slightly larger than the upper end of the heat radiation body 4 serving to support the insecticide mat 3. The inner wall, which determines the opening 22 in the direction in which the opening 22 is dug into the case lid 2, is formed by the upper vertical wall 22c and the lower downward tilting wall 22d by a plate passing through the middle portion of the upper plate 21 thickness. ).

The gap A (see FIG. 1) formed between the insecticide mat 3 and the vertical wall 22c of the opening 22 and the gap formed between the heat radiation member 4 and the inclined wall 22d of the opening 22 Air discharge interval that can serve as a free air passage between the inside and outside of the case lid 2 even after placing the insecticide mat 3 in place of the heat radiation body 4 due to B (see FIG. 2). (24) can be completely secured. The protrusion formed inwardly from the wall of the opening 22 is indicated by 25. These protrusions are attached to the purpose of precisely positioning the insecticide mat 3 at the center of the opening 22 and rectifying the air flow through the air doubling interval 24 between the insecticide mat 3 and the opening wall 22. .

Denoted at 26 is a settling portion dug under the upper surface of the top plate 21 so as to be gently inclined downward when facing from the periphery of the top plate 21 to the center. This settled portion is cut along a pair of main surfaces of the opening 22. This settling portion 26 has the function of (a) inserting the insecticide mat 3 into the opening 22 and placing it on the heat radiation plate 4, or (b) making it easy to remove it from the heat fume. Have

A shoulder portion 28 is formed along the entire circumference of the side wall 27 at the rear of the point where the top plate 21 and the side wall 27 of the case lid 2 cross each other. This shoulder 28 plays the role of attaching the catalyst 5 which is fully described next, and the support body 6 which serves to support the heat radiator 4 which can be used by receiving this catalyst in place. . The hole marked 28a is a screw hole used to attach this support. (27a) is a short portion formed along the entire circumference at the lower end of the side wall 27, and this short portion (27a) can be firmly engaged with the short portion (1e) formed on the outer wall (1d) of the case body (1). It must form. The entire case can be assembled by covering the upper part of the case body 1 with the case lid 2 and fitting the end portion 27a of the side wall to the outer wall end portion 1e of the case body 1. A screw groove may be dug into the side of the case lid 2 and the inner surface of the case body to screw the case body 1 and the case lid 2 together.

The insecticide mat 3 is a rectangular compressed fiber board impregnated with a chemical solution having an insecticidal effect. The rectangular shape has nothing to do with the function of the insecticide mat 3. Thus, the mat 3 may be in any form as long as it can be inserted into the opening 22 of the case lid 2.

The heat radiation body 4 is used for the purpose of supporting and supplying heat to the insecticide mat 3 and releasing the drug which the mat has an insecticidal effect into the mist. The heat radiation body 4 is composed of a heat radiation plate manufactured to be connected to the catalyst holding portion (5). An enlarged perspective view of the thermal radiation body 4 is shown in FIG. 3 (a).

The heat radiation body 4 is a horizontal heat radiation plate 41 which serves to support and heat the insecticide mat 3 placed thereon, and the heat radiation plate 4 is attached to face each other at a slight inclination downward from the rear surface of the heat radiation plate 41. A pair of lower side plates 42 attached in parallel to the above-described heat radiation plate 41 from the lower end of the side surface part 42, the lower side of the side part 42 described above, and the lower plate 43, respectively, And a catalyst holding portion 44 composed of a catalyst holding piece 441.

The corresponding edge 441a of each of the catalyst retaining pieces 441 is bent to extend inward toward the center of the heat radiation plate, and its lower end 441b is also bent to extend inward toward the center. The catalyst 5 is fixed in the normal position by the side edges 441a and the lower end 441b extending inwardly. This heat radiation body 4 is manufactured as a component using the metal plate excellent in thermal conductivity.

In some cases, the vent 42a may be provided to supply the air to the side surface part 42 and to exhaust the combustion gas discharged from the catalyst 5 from the heat radiator 4. The heat radiation plate 41 is made porous so that a part of the combustion gas generated from the monolith catalyst 5 is released through the pores of the heat radiation plate 41 to promote fuel oxidation reaction in the monolith catalyst 5 and It is possible to prevent combustion disturbance due to thermal reflux. However, the pores of the heat radiation plate 41 is not necessarily essential to the function of the heat radiation body (4).

A space C having a height fixed by the side part 42 may be formed between the heat radiation plate 41 and the lower plate 43. By the space C thus formed, the catalyst 5 can be prevented from coming into direct contact with the heat radiation plate 41. The distance of the space C, i.e., the distance between the catalyst and the heat radiation plate (the chemical heating portion) (shown as C cm in FIG. 2) is preferably at least 0.2 cm and more preferably in the range of 0.3 to 3.0 cm. If the catalyst and the heat radiation plate are in close contact with each other or if the distance is too small (C <0.2 cm), reflux of the combustion gas and combustion reaction of the fuel are disturbed and the heat radiation plate cannot be sufficiently heated. . It is the case where the catalyst and the top plate are separated from each other by a distance of 0.2 cm or more so that the combustion gas discharged from the catalyst can be refluxed and heated up to the required temperature.

One deformed thermal radiation body is described in FIG. 3 (b). This deformed thermal radiation body has the same heat radiation plate structure as described above, and has four narrow angle portions extending downward from the inner edge of the thermal radiation plate 41, the side plate 42, the lower plate 43 and the lower plate 43 ( 442 is formed. Each narrow angle 442 is composed of a narrow side wall 442a having a letter L-shaped cross section and a horizontal bottom 442b extending inwardly from the bottom of the side wall 442a, and serves to fix the catalyst in this position. Done. Two such corners 442 are attached to each other at the mentioned positions of the respective lower plates 43 described above.

The deformed heat radiation body can be made without any disturbing thermal conduction from the catalyst (5) to the heat radiation plate (41), and the heat radiation body (the catalyst holding portion 44 is composed of four narrow portions 442) 4) It has the advantage of reducing its own weight.

The monolithic catalyst 5 is manufactured in a square shape so as to be easily inserted into the corner 44 of the heat radiation plate 4 described above. It consists of a honeycomb ceramic carrier and a catalytically active metal such as platinum or palladium deposited on the ceramic carrier. The catalyst 5 used in the present invention is, of course, not limited to such a catalyst. Depending on the situation, the catalyst may be prepared in the form of beads aggregates or cotton balls.

(6) is a support for attaching the heat radiator 4 and the catalyst 5 to the case lid 2. This support is made of a disc having a diameter whose periphery can be adjacent to the inner surface of the side wall 27 of the lid 2. The central part of the support body 6 has a cavity 6a into which the circumferential part 44 of the heat radiation body 4 mentioned above can be fitted. In addition, at a suitable position of the support 6, there is provided a screw hole 6b into which a binding screw 7 can be fitted to bind it to the lid 2. The screw holes 6b for fitting these binding screws are perforated so as to be precisely aligned with the screw holes 28a formed in the shoulder 28 of the lid 2. The material of the support 6 is not particularly limited, but is preferably a material having no breathability or extremely weakness and having heat resistance and heat insulation. Therefore, it is preferable to manufacture with glass fiber as an example.

Numeral 8 denotes a fuel tank installed in the fuel container 1b. The tank is open at the top and filled with volatile fuel inside. The fuel tank 8 filled with fuel is installed in the fuel container lb of the case body 1. A space D is maintained between the fuel tank 8 and the catalyst 5 to maintain a fixed height.

The fuel used in the heated steamer described in FIGS. 1 and 2 should be volatile and capable of causing an exothermic reaction with the catalyst described above. Examples of fuels that meet these conditions include alcohol. It is preferable to select methanol or ethanol among alcohols. Specific examples of such alcohols that can be effectively used in the present invention include liquid alcohols, carboxyvinyl polymers, copolymers of maleic anhydride and isobutylene, copolymers of vinyl alcohol and acrylic acid, alcohols and alcohols gelled with starch derivatives. Solid fuel which has a main component is mentioned.

In the above-described heating fumigation with reference to FIGS. 1 and 2, the insecticide mat 3 is charged through the opening 22 of the case lid 2, and thus, on the heat radiation plate 41 of the heat radiation body 4. Lock it in place. The alcohol fuel evaporated from the fuel tank 8 in the form of a mist fills the space D and then rises through the catalyst located at the top of the fuel tank 8.

While passing through the catalyst, the fuel alcohol is oxidized by platinum or palladium catalyst and the combustion gas obtained is then discharged from the catalyst 5. This combustion gas continues to ascend to fill the space C, to be exhausted to the air exhaust pipe 42a, and to be mixed into the indoor air through the gaps A and B.

The reaction heat generated as the alcohol fuel is oxidized in the catalyst 5 is transferred to the heat radiation plate 41 of the heat radiation body 4 located above the catalyst 5 by the reflux of the combustion gas to raise the temperature of the plate 41. do. Separately, the heat of reaction generated in the catalyst conducts and transfers from the lower plate 43 to the heat radiation plate 41 via the side plate 42.

Therefore, the temperature of the heat radiation plate 41 rises uniformly, and the temperature of the plate 41 rises uniformly, and the insecticide mat 3 located on it or it heats uniformly. As a result, the pesticide active ingredient contained in the pesticide mat 3 diffuses into the air in the form of a mist through the opening 22 of the case lid 2.

During this process, the air necessary for the oxidation reaction of the alcohol fuel in the catalyst 5 is vented 42a of the side plate 42 through the air vent 23 installed on the top plate 21 of the case lid 2. The catalyst 5, which is its destination, is reached.

And a part of the air necessary for the oxidation reaction in the catalyst (5) is supplied to the catalyst (5) separately through the gap (A) and (B). The water obtained as a result of the fuel oxidation reaction is collected and stored in the water tank 1c of the case body 1.

The start of the fuel oxidation reaction in the catalyst (5) is prepared by preparing a filament heater (nichrome wire, platinum wire, etc.) or ceramic heater connected to the cell near the catalyst (5) and heating it to the temperature required for several seconds. It can also be promoted.

Next, the operation of the modified heat steamer of the present invention using liquefied gas as fuel will be described. The deformed heat steamer is located near a container filled with liquefied gas in the case, a nozzle connected to the container and a valve, a metal catalyst installed at a position where gas emitted from the nozzle may collide with the metal catalyst, It is composed of a heat radiation portion for supplying heat required for chemical vaporization, and the case is characterized in that the air supply and / or combustion gas discharge passage and the adjustment device for adjusting the opening and closing of the valve described above is provided. .

One feature of this modified invention is to position the metal catalyst with a certain height of space above the nozzle and to maintain a certain height of space above the metal catalyst to locate the thermal radiation body for the heat vaporizer of the medicament.

FIG. 4 is a plan view showing a typical heat steamer according to the above-described modification, and FIG. 5 is a cross-sectional view taken along the line III-III of FIG.

4 and 5, reference numeral 1 denotes a closed tubular case body, in which a container 8 'is provided with an injection valve device A for feeding liquefied gas into the container. This container 8 ′ is separated from the rest of the case body 1 by a separating wall in the middle of the case body 1. In addition, the case body 1 is provided with a ventilation hole 23 '.

(2) is a case lid. In the embodiment of the present invention, the case lid 2 has a letter “U” shape in cross section and is composed of a circular top plate 21 and a tubular side wall 27. The opening 22 on the front face 22a of the top plate is similar to the insect repellent mat 3 located in the heated steamer and is somewhat larger and similar to the upper surface of the heat radiator 4 which serves to support the insect repellent mat 3. Have a rectangular shape. The wall forming the opening 22 with respect to the direction in which the opening 22 is perforated in the upper plate is a vertical surface 22c parallel to the thickness direction of the upper plate 21. Reference numeral 25 is a lift formed on the vertical wall 22c of the opening which is raised inside the opening 22. These lifting are attached for the purpose of preventing the insect repellent mat 3 into the center of the opening 22 exactly in place and preventing the mat from leaving the position arbitrarily. Denoted at 26 is a settled portion which is dug down below the surface of the upper plate 21 to form a gentle inclination downward toward the center from the upper plate periphery and to be cut along a pair of main sides of the opening 22. These settled portions 26 have a function of easily inserting the insecticide mat 3 into the opening 22 and easily installing it on the heat radiation body 4 or easily removing it from the heat steamer.

The tubular side wall 27 has a through hole 23 through which air is freely moved and combustion gas is discharged.

The case lid 2 is hinged to the case body 1 using a support point 51 attached on the side wall 1d of the case body at the lowest end of the side wall 27 of the lid, and the case body 1 and It can be freely connected and disconnected.

A shoulder portion 28 is formed along the circumference of the entire side wall 27 on the rear surface of the portion where the upper plate 21 and the side wall 27 of the case lid 2 cross each other. The shoulder portion 28 is configured for the purpose of attaching the catalyst 5, which will be described in detail later, in place, and for attaching the heat radiator 4 which holds the catalyst 5 therein. Reference numeral 28a denotes a screw hole for fitting a screw that serves to attach the thermal radiation member 4.

(3) denotes an insecticide mat composed of a rectangular compressed fiber board impregnated with an insecticide active ingredient solution. This rectangular shape is independent of the function achieved by the pesticide mat.

The mat 3 may be held in any form as long as it can be inserted into the opening 22 of the case lid 2. (4) is a heat radiator whose function is to support the insecticide mat 3 and to heat it so that the mat 3 can release the insecticide component into the mist. The heat radiation body 4 is a heat radiation plate 41 designed to support and heat the insecticide mat 3, in the side wall tubular portion 42 and the side wall tubular body extending downward from the center of the heat radiation plate 41. It consists of a tubular body 44 which extends further in the downward direction to hold the catalyst therein.

All component components of the thermal radiation body 4 are made of metal material. The side wall tubular body 42 has a vent hole 42a through which the combustion gas generated from the catalyst can be released into the surrounding atmosphere. The heat radiation plate 41 may be made porous, and some of the combustion gas emitted from the monolithic catalyst 5 is exhausted through the pores of the heat radiation plate 41. In this way, the oxidation reaction of the fuel in the monolithic catalyst 5 can be enhanced, and the reflux of the combustion gas can be advanced without any obstacle.

The formation of such pores is not critical to the function of the thermal radiation plate.

The tubular body 44 is attached to the tubular body 44 by the flange 44a attached to the inner side of the tubular body 44 so that when the monolithic catalyst 5 is charged to the tubular body 44, the flange 44a is attached to the tubular body 44. It is kept safe. A space C of constant height is formed between the heat radiator 4 and the catalyst 5. This space (C) serves to separate the monolithic catalyst (5) from the heat radiation plate (41) supporting the insect repellent mat (3) thereon.

The monolithic catalyst 5 must be tubular in order to be inserted into the tubular body 44 of the heat radiation body 4 described above. It is composed of a honeycomb ceramic carrier and a catalytically active metal such as platinum or palladium deposited on the ceramic carrier. However, the catalyst 5 used in the present invention may be manufactured in the form of a bead aggregate or in the form of a lump or cotton ball, if not limited to this special form.

It is an advantageous method to separate the air inlet and the exhaust gas outlet by separating the nozzle upper space from the metal catalyst upper space by using a heat insulating material, and at the same time, use the heat insulating plate as a catalyst support.

8 'is a container for charging liquefied gas. This container is equipped with the nozzle 65 connected with the inside of a container via the valve | bulb X (FIG. 6). This container 8 'is filled with liquefied gas used as fuel.

As the fuel, any liquefied gas in which a gas can cause an oxidation reaction with the help of the catalyst 5 described above can be used. Specific examples of liquefied gases that meet these requirements include liquefied petroleum gas (LPG), dimethyl ether, hexane, benzene, and gases used for lighters. The container 8 'is equipped with a valve adjusting device B that can control the opening and closing of the valve X so as to control the discharge of the liquefied gas. This adjusting device (B) is interlocked with the switch 61 attached to the case body to regulate the switch, so that the supply of the catalyst 5 medium to the liquefied gas is regulated, and consequently, the heat radiation body 4 Keep the temperature uniform.

In the constructed heated fumigation as described above, the insecticide mat 3 is inserted into the opening 22 of the case lid 2 and placed on the heat radiation plate 41 of the heat radiation body 4. The liquefied gas fuel is discharged from the vessel 8 'and passes through the nozzles and passes through the catalyst 5 located above the vessel 8' with the air introduced through the vents 23 and 23 '. . In the catalyst (5), liquefied gas fuel is oxidized by palladium or platinum catalyst and the obtained combustion gas is discharged from the catalyst (5). This combustion gas continuously rises to fill the space C and is discharged to the atmosphere through the air vent 23 through the air vent 42a provided in the side wall tubular body 42 of the heat radiation body 4. The reaction heat generated by the oxidation reaction of the liquefied gas fuel in the catalyst 5 is transferred to the heat radiation plate 41 of the heat radiation body 4 located above the catalyst, so that the temperature of the heat radiation plate 41 is increased. The heat of reaction generated inside the catalyst 5 is also transferred to the heat radiation plate 41 through the side wall tubular body 42 of the heat radiation body 4 made of a metal material. As a result, the temperature of the heat radiation plate 41 becomes uniform.

By raising the temperature of the heat radiation plate 41 in this way, the heat radiation plate is such that the insecticide active ingredient contained in the insecticide mat 3 can be dispersed in the mist through the opening 22 of the case lid 2 into the atmosphere. The insecticide mat 3 located on 41 is heated sufficiently uniformly. On the other hand, the air required for the oxidation reaction of the liquefied gas fuel in the catalyst is introduced through the vent 23 provided in the upper plate of the case lid 2 and the vent 231 of the case body, it is supplied to the catalyst (5).

From now on, the operation of the valve control device during the operation of the heating steam of the above-described structure will be described.

Figure 6 is an enlarged view of the valve control device (B) used in the heating fumigation of the present invention.

First, the stopper 70 is released, and then the switch 61 is pushed to the valve opening position (for releasing gas). As a result, the rocking plate 62 is operated to push up the support metal 63 and the pushed support metal 63 compresses the spring 64. The upward force generated by the spring thus pushes up the movable valve body 66 to which the nozzle is attached.

The valve member 67 is spaced apart from the fixed valve seat 68 by the upward movement of the movable valve body 66, and as a result, the valve X consisting of the valve member 67 and the fixed valve seat 68 is Open. By opening the valve X, the liquefied gas is discharged through the nozzle 65 via the induction port 69 provided in the movable valve body.

At this time, the case lid 2 is opened to expose the nozzle 65 and ignited by a match or a lighter to the liquefied gas emitted from the nozzle 65. Then, the case lid 2 is firmly put on the case body 1 again, and combustion of the liquefied gas is continued for about 10 seconds until the temperature of the catalyst 5 rises to the above-mentioned temperature. In addition, an electric heating device composed of a filament heater (nitrom wire, platinum wire, etc.) or a ceramic heater connected to the cell may further heat the catalyst 5 to the required temperature.

In this step, the stopper 70 is completely released and the switch 61 is pushed further.

The pressure plate 71 connected to the switch 61 consequently rotates the rotary plate 72 in the direction of the arrow and integrates the downward motion to the tip of the pusher 73 connected to the rotary plate 72. Accordingly, the nozzle 65 connected to the tip of the lowering device 73 is also moved downward to close the valve X by closing the valve member 67 to the fixed valve seat 68.

In this way, the liquefied gas discharge from the nozzle 65 is stopped by locking the valve X, and the liquefied gas flame is turned off. After the flame is turned off, the switch 61 is moved downward and the stopper 70 is fixed at the valve opening position. By fixing the stopper in the valve opening position in this way, the valve X is opened and gas discharge from the nozzle 65 continues.

Since the catalyst 5 maintains the aforementioned heating conditions as it is, the liquefied gas discharged from the nozzle 65 causes a rapid reaction to maintain the heated state of the catalyst.

In order to prevent the catalyst 5 from being heated too much, the bimetal 75 is used to adjust the flow rate of the liquefied gas passing through the use valve X. In detail, when the movable valve body 66 is placed in the elastic state, as shown in the figure, the upward force is maintained. Therefore, the bimetal 75 was provided so that the downward pressure may be applied to the nozzle 65 against this upward force. The degree of dropping of the nozzle 65, that is, the degree of displacement of the movable valve body 66 depends on the temperature of the catalyst 5 passing through this bimetal. In conclusion, the valve closing degree by the valve member 67 and the fixed valve seat 68 is determined by the dropping force of the bimetal 75.

As a result, the amount of liquefied gas discharged through the nozzle 65 is automatically controlled by the temperature of the catalyst 5, and as a result of this, the reaction temperature of the catalyst 5 can be maintained at a constant level. Then, the heat of reaction actually generated in the catalyst 5 keeps the temperature of the heat radiator 41 of the heat radiator 4 uniform as described above, and uniformly holds the pesticide mat 3 located on the heat radiator plate 41. Heating causes the insecticide active ingredient of the mat 3 to be released in the mist state.

The use of the present invention of the heating steamer can be finished by releasing the stopper fixed state and immediately moving the switch 61 downward to put it in the valve closing position. This downward movement of the switch 61 rotates the rock plate 62 counterclockwise and consequently moves the support metal 63 connected to the rock plate 62 downward. Due to the downward movement of the supporting metal, the force of the spring 64 in the direction of lifting the nozzle 65 is weakened. As a result, the nozzle 65 moves downward and the valve member 67 is in close contact with the fixed valve seat 68. In this way, the valve X is locked.

The present invention of the present invention, which is modified to use liquefied gas as a fuel, is not limited to the structure described in FIGS. 4 and 5. If necessary, the tubular heat radiation site may be positioned along the outer side of the catalyst 5, and a donor-type insecticide mat may be inserted into the heat radiation body. Typical heating fumes using such tubular thermal radiators and thus using donor insecticide mats are described in FIGS. 7 and 8.

FIG. 7 is a plan view illustrating another heating steamer using liquefied gas fuel, and FIG. 8 is a cross-sectional view taken along the line IV-IV of FIG.

In FIG. 8, the case body 1 includes a liquefied gas storage container 8 '. This container 8 'is connected to the nozzle 65 via a valve control device B located in the middle. These parts of the fumigation are the same as the corresponding parts in the embodiment described in FIGS. 5 and 6.

100 is a tubular case body, and is composed of a circular plate 101 having a circular opening 103 and a tubular side wall 102 therein. Circular opening 103 is composed of a tube connected to the built-in tubular side wall 104 constituting a part of the tubular case body 100. The lower end of the tubular side wall 102 is connected to the perforated side wall (l05). The metal mesh 106 is attached to the inside of the side wall 105. Therefore, the air is freely introduced into the tubular case body through the side wall 105, and the yabber discharged in the mist form from the pesticide mat is discharged to the outside of the tubular case body.

The metal catalyst 5 is attached to the built-in tubular side wall 104 together with the heat radiation tube 107. The heat radiation tube 107 is surrounded by a metal body 108, and the insecticide mat holder 109 is assembled to the metal body.

In using the heat fume constructed as described above, the insecticide mat 3 is manufactured in the form of a donor to be inserted into the holder 109. Therefore, as a preparatory step for the actual use of the fumigation, the hinge of the support point 51 is used to open the tubular case body and insert the pesticide mat 3 around the holder 109.

The liquefied gas discharged from the nozzle 65 causes an oxidation reaction in the catalyst 5 heated by the reaction heat, and as a result, the heat radiation tube 107 is simultaneously heated. This heat is conducted to the holder 109 through the metal body 108 and is used to uniformly heat the pesticide mat 3 surrounding the holder 109. By this heating, the pesticide active ingredient contained in the mat 3 is released into the mist, and it is dispersed into the atmosphere from the inside of the tubular case body 100 through the metal mesh 109 and the porous side wall 105. The combustion gas obtained by the reaction of the liquefied gas fuel in the catalyst 5 is discharged to the outside through the circular opening.

In this heating steamer, the liquefied gas fuel release valve is adjusted as the bimetal 75 to maintain the heating temperature uniformly. The adjustment operation performed at this time is similar to the adjustment operation already described in FIGS. 2 and 3.

In the fumigator manufactured as described above, the metal body 108 may be formed in a semi-circular columnar shape in a cross section, and in the form of a flat plate with an insecticide mat holder, and the pesticide mat manufactured in the flat form may be inserted and used in place.

In the embodiment described so far, the liquefied gas charging container 8 'is embedded in the corresponding case body 1 in the same manner, and the injection valve device A can freely fill the liquefied gas in the container 8' (A). (Figure 5) is provided.

An enlarged view of the injection valve device A is shown in FIG. The operation principle of this injection valve device A + is the same as that of the injection valve device found in a normal gas lighter. In detail, the movable body 81 is closed by the seal 82 which is subjected to the force by the spring 83. While injecting the liquefied gas, the movable body 81 is moved upward in FIG. 9, and as a result, the seal 82 is also moved upward to open the injection port (opening the valve).

The liquefied gas storage container 8 'is not limited to the container installed in the case body 1. In some cases, a liquefied gas container of a cartridge type similar to a gas cylinder may be manufactured separately from the case body 1 and used separately from the case body 1.

In the present invention, as a pesticide that can be used in a heating fume, there may be mentioned various insecticides that have been used as an electric mosquito insecticide, for example. Typical examples of such insecticides include 3-allyl-2-methylcyclopenta-2-en-4-one-1-yl dl-cis / trans-cryxanthate (alletrin), 3-allyl-2-methylcyclopenta- 2-en-4-one-1-yl d-cis / trans-xanthatemate, d-3-allyl-2-methylcyclopentan-2-en-4-one-1-yl d-trans-xanthate Mate, 5-propargyl-2-furylmethyl d-cis / trans-crysanthate, 1-ethynyl-2-methylpenta-2-en-1-yl d-cis / trans chrysanthate and 1-on And pyrethrinth insecticides such as tinyl-2-methylpenta-2-en-1-yl 2, 2, 3, 3-tetramethyl cyclo propane carboxylate.

In addition, typical examples of pyrethrin adjuvants which may be used in combination with the above-described insecticides include piperonyl butoxide, N- (2-ethylhexyl) -1-isopropyl-4-methylbicyclo- [2, 2, 2] -Octo-5-ene-2, 3-ticarboxyoxyimide and octachlorodipropyl ether. These pesticide components are impregnated and mixed into the compressed fiber mat. In addition to the pesticide component described above, the mat may be an antioxidant such as BHT, BHA or DBH, which may act as a stabilizer against the insecticide component, and a dye that may discolor when exposed to heat, thereby allowing the user to easily read the use of the mat. You can also mix with spices.

Instead of the mat impregnated with the pesticide active ingredient solution, the present invention may use an aluminum container filled with a solid chemical that can be vaporized by inserting into the fume attempted in the present invention. If necessary, the pesticide may be replaced with a disinfectant, an indoor fragrance or a deodorant. Any fungicide with a volatility of alcohol or dioxin can be used for this purpose.

The heat vaporizer of the present invention is not limited to the structure described in FIGS. 1 to 8. For example, a vent for supplying the air necessary for the catalytic oxidation of the fuel and for releasing the combustion gas obtained as a result of the oxidation reaction from the case body to the atmosphere is essential. Such vents may, if necessary, be installed on the side wall of the case lid or on the outer wall of the case body, rather than the locations described in the figures. If an air supply vent is installed on the outer wall of the case body, it shall be installed at the lowest possible end of the outer wall of the case body or on the bottom of the case body to prevent evaporated fuel from dissipating through the vent. In some cases, one vent may be used simultaneously for two purposes, one for supplying air and one for discharging flue gas. In such a case, the gap formed between the insecticide mat and the opening may be used as a vent, and another vent is not required.

The shape of the thermal radiation plate is not limited to the shape described in the drawings. The catalyst form is also not limited to the form described in the figures. For example, it may be advantageous to eliminate the air gaps formed around the heat radiation plate and to place the air discharge openings at a much lower height than the heat radiation plate in order to prevent chemicals released from the mat from adhering to the catalyst. have.

The catalyst may be inserted into the receptor separately installed from the above-described heat radiation plate in the form of a plate, and the catalyst may be charged in place to penetrate the support. The receptor then consists of a vertically opposite support capable of biting the catalyst therebetween. As described above, when the catalyst receptor is provided separately from the heat radiation plate, the side body may be omitted. In this case, however, a fixed height space C must be provided between the heat radiation plate and the catalyst. The height of this space C, i.e. the distance separating the catalyst and the heat radiation plate from each other (indicated by C cm in FIG. 2), should be maintained at least 0.2 cm and preferably in the range of 0.3 to 3.0 cm. If the catalyst and the heat radiation plate are in close contact (C = 0 cm) or the distance is too small (C <0.2 cm), the reflux of the combustion gas and the oxidation reaction cannot proceed smoothly, so that the heat radiation plate cannot be sufficiently heated. The heat radiation plate can be most efficiently heated by the reflux heat of the combustion gas emitted from the catalyst only when the catalyst and the heat radiation plate are spaced at least 0.2 cm from each other.

The catalyst form is not limited to the form described in the figures. This catalyst may be a cylindrical monolithic catalyst. The fuel-filled container has an opening at the top thereof and can serve as the present invention's heating steamer as long as the filled fuel can be effectively evaporated by a steamer.

A funnel-shaped water container may be installed inside the fume to prevent the water produced during the oxidation reaction from entering the fuel container. Otherwise, an upward flare can be attached to the top of the neck of the fuel tank to connect to a funnel-shaped water container.

If gel fuels or solid fuels are used, the fuel may be wrapped by using a cloth, foam or porous ceramic or plastic material such as gauze or nonwoven material, or other material that does not interfere with chemical evaporation. It is very beneficial for the purpose of preventing the leakage loss from the container or controlling the amount of fuel to evaporate.

The height of the space D, i.e., the distance d at which the fuel and catalyst are separated from each other, should be at least 0.3 cm, preferably in the range from 0.5 to 10.0 cm. If the fuel and the catalyst is in close contact (d = 0 cm) or too narrow (d <0.3 cm), there is a disadvantage that the evaporated fuel is not sufficiently introduced into the catalyst and flows out. In order for the evaporated fuel to pass slowly through the catalyst and for the oxidation reaction to proceed advantageously, the fuel and the catalyst are kept at a distance of 0.3 cm or more from each other.

When volatile solid fuel or volatile liquid fuel is used, the fuel container containing the fuel can be made to serve as a container for fresh replenishment of fuel, and the container is specifically designed for storing fuel. Can be used as a container substitute.

The present invention will now be described in more detail as a next embodiment of the present invention.

Example 1

5 g 5-propargyl-2-furylmethyl-d-cis / trans chrysanthate, 15 g N- (2-ethylhexyl) -1-isopropyl-4-methyl-bicyclo [2, 2, 2] Oct-5-ene-2, 3-dicarboxyimide, 15 g of DBH and 0.2 g of 1,4-diisopropylaminoanthraquinone were dissolved in acetone and the total volume was made up to 100 ml. A fiber press plate of 35 × 22 × 28 mm is impregnated in 1 ml of this obtained solution. The wet plate is roughly dried to prepare an insecticide mat. This insecticide mat is used by being installed on the heat radiation plate of the heating fumigation described in FIG. 1 and FIG.

Example 2

6 g 3-allyl-2-methylcyclopenta-2-en-4-one-1-yl d-cis / trans-crylate tetramate, 4 g piperonylbutoxide, 2 g BHT and 0.3 g 1, 4-dimethylaminoanthraquinone was dissolved in acetone and the total volume was 100 ml. The same fiber compression plate as that used in Example 1 was impregnated in a 1 ml obtained solution and treated in a similar manner to prepare an insecticide mat. This mat is used for installation on the heat radiation plate of the heating fume described in FIGS.

Example 3

10 g of 1-ethynyl-2-methylpenta-2-en-1-yl d-cis / trans-cryxanthate, 8 g of N- (2-ethylhexyl) -1-isopropyl-4-methylbicyclo [2,2,2] octo-5-one-2,3-dicarboxyimide, 1 g of DBH, 0.8 g of fragrance, 0.2 g of 1,4-diisopropyl aminoanthraquinone and 10 g of odorless kerosene The solution is prepared by mixing and heating the resulting mixture to promote the melting of the solid. A pesticide mat was prepared by impregnating 0.3 g of the obtained fiber pressing plate as used in Example 1 and treating it similarly. This mat is used by being installed on the heat radiation plate of the heating fumigation described in FIGS. 1 and 2.

The use of this fumigation proved to be equivalent to the mosquitoes available on the market for 10 hours.

Example 4

A 30 x 20 x 3 mm ceramic plate is impregnated with a 2 ml ethanol solution in which 1 g dioxane is dissolved. A wet ceramic plate is installed on the heat radiation plate on the heat vaporizer described in FIGS. 1 and 2 to use to heat the room. The number of indoor bacteria before and after fumigation was compared using a Petri-Dish method using agar culture medium. As a result of this test, it was concluded that fumigation reduced the number of indoor bacteria to less than 1%.

Example 5

A gel material is prepared by dissolving 1 g of carboxyvinyl polymer (commercially available under the trademark High-bis Waco 104) in a 47 g ethanol solution containing 5 g perfume and then adding 2 g of an aqueous 2% triethanolamine solution to the obtained solution. 20 g of this gelled material was filled in an aluminum container and installed on a heat radiation plate of a heating fume described in FIGS. 1 and 2 to be used as an indoor fragrance.

Example 6

The same fiber compression plate as used in Example 1 was impregnated with a 1 ml alcohol solution in which 0.5 g of deodorant alcohol extract, which is present in the fresh Camellia leaves of Theaceae. This press plate was installed on the heat radiation plate of the heating fumigation described in Figs. 1 and 2 and used for the deodorizing effect test in the bathroom. This fumigation effect eliminated the odor in the bathroom.

The present invention will be explained in more detail by the following test.

Test 1

25 g of gelled material containing 90 parts of methanol, 8 parts of ethanol and 2 parts of D-Solbit Benzylidene Derivative (commercially available under the Gelol D trademark) and each of the thermal radiation plates in Examples 1 and 2 Insecticide mat was used to test the insecticidal effect over time as the heat fume described in FIGS. 1 and 2. The test results are shown in FIG. The term "relative potency" used in the drawings is measured at an hourly interval, and means a fumigation effect as a comparison value based on 1.0 as an effect measured after one hour has elapsed. It can be clearly seen from FIG. 10 that the insecticide mats of Examples 1 and 2 have a high insecticidal effect.

Test 2

In the heated steamer described in FIGS. 1 and 2, the distance between the catalyst 5 and the heat radiation plate 41 (c cm) and the fuel container 8 filled with the catalyst 5 and the fuel (the upper end of the container opening). The temperature of the thermal radiation body 4 was measured while changing the distance (d cm) from each test and operating with the gas passage open in some tests and closed in another test. The test results are shown in Table 1. In this test, solid fuel (water: methanol = 1: 8) prepared by dissolving 6 parts of stearic acid in 86 parts of methanol and adding 8 parts of 12.5% aqueous sodium hydroxide solution to the obtained solution was used as a fume fuel. The temperature of the room where the test was conducted was maintained at 25 ℃ ± 1 ℃.

* "Average temperature" means the average temperature measured every hour from 1 hour to 10 hours.

From the results in Table 1 we can explain the following: When comparing the data of Test No. 1 with those of Test Nos. 2 to 10, it is necessary to maintain the distance between the fuel container (fuel) 8 and the catalyst 5, and by adjusting the gap, It was found that the temperature can be controlled. Comparing the data of Test No. 5 and Test No. 11 shows that it is also necessary to maintain the gap between the catalyst 5 and the heat radiation plate 41. Comparing the data of Test No. 5 and Test Nos. 11 to 17, it can be seen that the magnitude of the gap (c cm) affects the temperature of the heat radiation plate 41. It is possible to arbitrarily select the temperature of the heat radiation plate 41 by appropriately combining the interval c cm and d cm according to the type of drug and the fumigation purpose. Comparing the data in Test No. 4 and Test No. 18 proves that gas passages are necessary for the function of the fume function. It is concluded that the temperature of the heat radiation plate must be increased when the gas passage is equipped and it is fixed at the temperature of the heat radiation plate if the gas passage is fixed. I could get it.

The test results also indicate that the gas passages must not be provided on the top plate of the case lid 2, but also to the outer wall 1d of the case body 1 and to the side wall 27 of the case lid 2, In the case of a passage, the effect obtained by the passage is the same.

The test data demonstrated that the opening size at the top of the fuel container was dependent on the distance between the fuel and fuel container and catalyst actually used, but the temperature of the thermal radiation plate was stabilized when all these conditions were fixed.

In order to sufficiently heat the heat radiation plate in the present invention with a heat source as a result of the above test, a constant distance is maintained between the fuel container and the catalyst, and a constant distance between the catalyst and the heat radiation plate is further provided. The fact that a gas passage should be provided has been obtained, and other conditions of the fumigation can be changed as appropriate depending on the purpose of the fumigation, the type of medicine and fuel.

Exam 3

The temperatures of the corresponding thermal radiation plates were measured by varying the type of volatile fuel used as the heating steam of FIGS. 1 and 2 and the heating steam of FIGS. 4 and 5. The room temperature of the room where this test was conducted was maintained at 25 ° C ± 1 ° C.

* "Average temperature" means the average temperature measured every hour from 1 hour to 10 hours.

As a result of the above test 3, if the fuel used is volatile at room temperature, the heat steam of the present invention can obtain the temperature required for the heat radiation plate, and there is no difference in changing the type of volatile fuel. .

In test Nos. 4 to 8, the heat generation rate can be increased by applying heat to the catalyst at the time when the steam is used.

As can be clearly seen from the foregoing, the present invention is to heat the volatile fuel or liquefied gas fuel in the steam casing case and to maintain a certain distance above the fuel to position the catalyst, to oxidize the fuel in the catalyst and to remove the heat of oxidation reaction The thermal radiation plate is inverted by a predetermined distance to the upper portion of the catalyst to raise the temperature of the thermal radiation plate, and the thermal radiation plate is to induce the evaporation of the medicinal agent by heating it. Compared with the prior drug vaporizer which uses electricity as a heat source for drug evaporation, the present invention has a merit that it is easy to manufacture and is not restricted by the place of use. Since the heat radiation plate is uniformly heated by fuel oxidation in the presence of a catalyst, and as a result, the drug is uniformly evaporated, the drug that has been impregnated in the fiber pressing mat and can be easily evaporated out of the mat. The fumigation of the present invention also has an excellent advantage of being able to uniformly maintain a constant temperature which has been judged not to be obtained by the prior fumigation.

In particular, the present invention can use a liquefied gas as a fuel that can cause an oxidation reaction in the presence of a metal catalyst, and thus can easily replenish the liquefied gas and can easily control the emission of the fuel. Will have

Therefore, the present invention heat steamer is very suitable to be portable.
