Description

The present invention relates to a liquid fuming transpiration agent and a method of using the same. More specifically, the present invention relates to a liquid fuming vaporizer capable of evaporating (evaporating) into the atmosphere in the form of smoke (aerosol state) by heating, and a method for transpiring a chemical using the liquid fuming vaporizer. , And the chemical evaporator used to carry out the method. The above-mentioned "transpiration method of chemicals" of the present invention can also be said to be a method of treating a space with a chemical.

Conventionally, as a device for evaporating a transpiration agent containing chemicals such as an air freshener, a deodorant, and an insect repellent into a space such as a room, a spray type transpiration device, a stationary type transpiration device, and a natural evaporation type transpiration device are used. A heating type evaporator is known.

In the natural evaporation type evaporator, the liquid evaporative agent containing the chemical is placed as it is or in a state of being impregnated with the core material made of a porous material so that the evaporative agent evaporates naturally in the indoor space, so that it evaporates. The amount of evaporation of the agent is small, and the effect of the agent may not be fully exerted in the indoor space. Further, in the natural evaporation type transpiration device, since the transpiration agent containing the chemical is stored in the open container in a state of being exposed to the outside air, the indoor temperature may rise or the air in the indoor space may be replaced. There is a problem that the disappearance of the transpiration agent is accelerated, and the sustainability of the desired drug effect may not be guaranteed.

On the other hand, as a heating type transpiration device, the transpiration agent containing the chemical is electrically heated when necessary to actively evaporate, and the chemical component can be efficiently filled in the indoor space or evaporated in the form of smoke. There are known electric heating evaporators that can be used. For example, as the latter transpiration device capable of smoky evaporation, specifically, the transpiration agent is evaporated in the form of smoke by heating a core material impregnated with a liquid transpiration agent containing a chemical, and the transpiration agent is evaporated. However, there are known evaporators configured to pass through a tunnel passage provided above the core material and rise upward (Patent Documents 1 and 2). Such a conventional electric heating type transpiration device can increase the evaporation rate of the transpiration agent by energizing and heating at the time of use, and can efficiently obtain the desired effect, but is different from the natural evaporation type transpiration device. Similarly, since the transpiration agent is stored in an open container in a state of being exposed to the outside air, it continues to evaporate even when it is not heated, and depending on the conditions in the indoor space, the transpiration agent evaporates faster, and the transpiration agent evaporates in a short period of time. There is a problem that the effect of is lost.

Specifically, for example, the vaporizer starts from 30% by weight of the A component having a vapor pressure of α at 20 ° C., 10% by weight of the B component having a vapor pressure of β, and 60% by weight of the C component having a vapor pressure of γ. If so, its average vapor pressure can be calculated from the following formula:

Further, the vaporizer of the present invention is characterized in that the average molecular weight of the soluble component contained therein is 150 to 250. The average molecular weight is preferably 150 to 200.
Here, the average molecular weight means the average value of each molecular weight of the soluble components contained in the vaporizer of the present invention. Specifically, the average molecular weight can be calculated from the molecular weight of the soluble component contained in the vaporizer and the blending ratio (weight ratio) thereof. For example, the soluble components contained in the vaporizer are A component (molecular weight α), B component (molecular weight β) and C component (molecular weight γ), and each component when the total amount of A to C components is 100 parts by weight. When the weight ratios are A component: 30 parts by weight, B component: 10 parts by weight, and C component: 60 parts by weight, the average molecular weight can be calculated from the following formula:

Here, the soluble components means a component dissolved in the evaporation liquid of interest (liquid smoke emission transpiration agent) (20 ± 5 ℃). Whether or not the transpiration solution is soluble in the solvent can be determined based on the solubility determination method and criteria specified by the Japanese Pharmacopoeia. Specifically, when the target component is a solid, it can be judged from the extent to which it dissolves within 30 minutes when it is made into a powder, put in a solvent, and vigorously shaken at 20 ± 5 ° C. every 5 minutes for 30 seconds. In this case, it is judged from "slightly insoluble" (the amount of solvent required to dissolve 1 g or 1 ml of solute is 30 ml or more and less than 100 ml) to "extremely soluble" (the amount of solvent required to dissolve 1 g or 1 ml of solute is less than 1 ml). Ingredients can be mentioned. That is, when evaluated by the above method, it can be determined that a component in which the amount of solvent required to dissolve 1 g or 1 ml of the solute is less than 100 ml is a soluble component. In addition, "dissolve (dissolve, dissolve)" in a solvent means that the target component is clearly soluble or miscible in the solvent, and no fibrous substances or the like are observed in the solution, or even if they are observed, they are slightly. It means that it is.

In the vaporizing solution of the present invention, the above-mentioned solvents and chemicals, and other substances, if necessary, so that the average vapor pressure of the final solution at 20 ° C. is 0.1 to 10 Pa and the average molecular weight of the soluble component is 150 to 250. It can be prepared by appropriately selecting and blending various components and mixing them. Further, the transpiration solution of the present invention is housed in a cylindrical round mouth bottle having a circular opening with a diameter of 2 mm in a volume of 1 mL thereof, and is kept under constant temperature and humidity conditions (27 ° C., 60%) in the opened state. When left for 2 months, it is preferable to adjust so that the amount of decrease after 2 months is 5% by weight or less of the total amount at the beginning. Preferably, the amount of decrease after 2 months is 4% by weight or less of the total amount initially, and more preferably 3% by weight or less.

The transpiration liquid agent of the present invention is used by supplying it to a heating element when it is desired to evaporate the transpiration liquid agent and the chemical components contained therein into the atmosphere (space). Here, the supply of the transpiration solution to the heating element means that the transpiration solution is brought into contact with or close to the heating element in an atmospheric atmosphere (in the air in the space). In order to efficiently transfer the heat of the heating element to the evaporation liquid and increase the evaporation amount (evaporation amount in the form of smoke) of the evaporation liquid agent, it is preferable to bring the evaporation liquid agent into contact with the heating element.

In this case, the evaporation liquid may be dropped (under the droplet) as it is on the heating element, or may be applied. The method and means used under the droplet may be any method and means capable of dropping the evaporation liquid onto the heating element, and the mechanism and the like thereof are not particularly limited. Similarly, the coating method and means may be any method or means capable of coating the evaporation liquid on the heating element, and the mechanism or the like is not particularly limited.

Further, the vaporizing liquid agent may be brought close to or in contact with the heating element via a core material impregnated with the porous base material. As one aspect of the core material, the core material is used by being inserted into a container (container) containing a transpiration solution in the chemical transpiration device of the present invention as described later. By doing so, as long as the transpiration liquid remains in the container, the core material can be used in a state where the transpiration liquid is sucked up from the container by the capillary phenomenon and impregnated with the transpiration liquid.

As the porous base material that can be used for preparing the core material to be impregnated with the evaporation liquid, any material that can be impregnated with the evaporation liquid of the present invention and has heat resistance that can withstand heating by a heating element is used. The material is not particularly limited. More preferably, it is made of a material that can absorb the transpiration solution and suck it up by capillarity. Examples of the material of such a porous base material include glass fiber, carbon fiber, fiber in which acrylic fiber and melamine resin are kneaded, PEEK (polyetheretherketone) fiber and the like. Glass fiber and carbon fiber are preferable.

When supplying the evaporation liquid to the heating element via the core material, it is desirable that at least a part of the core material impregnated with the fuming vaporizing liquid is brought into contact with the heating element, but if smoke formation is possible, the core This may be done by keeping at least a part of the material in close proximity to the heating element.

The core material may be a porous base material impregnated with a predetermined amount of the transpiration solution of the present invention in advance, or the transpiration solution can be sucked up into a container (container) containing the transpiration solution by capillarity. It may be configured so that the transpiration liquid agent is continuously supplied to the core material portion which is inserted in such a state and is in contact with or in close proximity to the heating element.

As the shape of the core material, as shown in FIGS. 1 and 2, a rod shape (cylindrical shape) in which both tips and the body portion have substantially the same cross-sectional shape and size can be exemplified. However, it can be appropriately set depending on the supply method to the heating element. The size thereof can be appropriately set according to the amount of the vaporizer to be impregnated, the material of the core material, the size of the steamer described later, and the like. Although not limited, for example, in the case of the columnar one, a diameter of 1 to 10 mm, preferably 1 to 3 mm; a length of 10 to 50 mm, preferably 20 to 30 mm can be exemplified. As shown in FIGS. 1 and 2, the core material may be held by the support. In this case, the exposed portion from the support is not limited, but 1 to 10 mm, preferably 5 to 10 mm is exemplified. You can do this.

The vaporizer of the present invention is preferably used by being housed in a container in which a core material is inserted, as described above. Since the transpirant is a consumable item in itself, it is independently subject to commercial transactions as a "refill". Further, the core material impregnated with the transpiration liquid agent of the present invention is also independently subject to commercial transactions as a "refill product". The core material impregnated with the transpiration liquid agent can be a target product for commercial transactions as a "refill product" together with a support for holding the core material or fixing it to the container of the chemical transpiration agent. Therefore, the transpiration liquid agent and the core material impregnated with the transpiration liquid agent (including the core material held on the support) are housed and sealed in an airtight and liquidtight sealed container (packaging body), respectively. It can be distributed to the market in the state. The airtight and liquid-tight sealed container (packaging body) may be any airtight or liquid-tight container so that the transpiration liquid does not volatilize and leak, and is not particularly limited as long as it is airtight or liquid-tight. .. For example, a resin bottle having liquidtightness and airtightness, a pouch formed from a resin sheet, and the like can be exemplified.

2. Chemical Transpiration Method The chemical evaporation method of the present invention can be carried out by supplying a liquid agent containing a chemical and a solvent having a boiling point of 170 ° C. or higher to a heating element that generates heat at a temperature of 100 ° C. or higher. By doing so, the above liquid agent and the agent contained therein can be evaporated (evaporated) into the atmosphere (space) in the form of smoke. Here, examples of the liquid agent include the above-mentioned liquid fuming transpiration agent (smoking transpiration liquid agent) of the present invention, and the solvent and the chemical contained therein are also as described above.

The supply of the evaporation liquid to the heating element can be carried out by bringing the evaporation liquid into contact with or in close proximity to the heating element, as described above. Specifically, the application of the transpiration liquid agent to the heating element under droplets or applied can be exemplified. Further, the core material prepared by impregnating the porous base material with the evaporation liquid may be brought into contact with or close to the heating element.

Further, as the heating element used for heating the transpiration solution, any heating element that can be heated to a predetermined temperature is used, but an electric heating element that generates heat by energization is preferably used. The heat generated by the electric heating body can be canceled by shutting off (turning off) the energization. Examples of such an electric heater include a heating wire, a PTC heater, a ceramic heater, a fixed resistance heater, and the like. When power is applied by a battery type, a heating wire is preferable from the viewpoint of power consumption.

In the present invention, in an air atmosphere (in the atmosphere of the space), the above-mentioned transpiration solution supplied to the heating element is heated by the heating element heated to 100 ° C. or higher by energization, whereby the heated transpiration solution forms an aerosol. , Visible smoke-like and evaporable. When the core material impregnated with the evaporation liquid is heated, the evaporation liquid forms an aerosol at the contact portion between the core material and the heating element or the vicinity portion between the core material and the heating element, and is in the form of visible smoke. It becomes possible to evaporate.

In the present invention, the temperature at which the heating element generates heat when energized is not particularly limited as long as it is 100 ° C. or higher, but from the viewpoint of enhancing the ability to form smoke (aerosol) while providing safety for indoor use. Is preferably 100 to 350 ° C., more preferably 120 to 310 ° C., and 120 to 250 ° C. can be exemplified in consideration of safety in use.

In the present invention, at least one heating element for heating the evapotranspiration agent may be used, but if the amount of transpiration of the transpiration-like chemical is increased or two or more smokes are formed, the evapotranspiration agent or its impregnation is impregnated. Two or more heating elements may be brought into contact with or close to the core material.

According to the chemical evaporation method of the present invention, the chemical can be evaporated into the atmosphere (for example, an indoor space) by heating the evaporation liquid through a heating element that generates heat to 100 ° C. or higher by energization, thus allowing the chemical to evaporate into the atmosphere (for example, an indoor space). The agent can treat the air (eg, indoor space). Specifically, if the drug contains a fragrance component, the air (for example, indoor space) can be aroma-treated; if the drug contains a deodorant component, the air (for example, indoor space) can be extinguished. It can be deodorized; if the drug contains a fragrance and a deodorant component, the air (for example, a house space) can be deodorized and aroma treated. In addition, if the drug contains an antibacterial component, the air (for example, indoor space) can be treated with antibacterial treatment; if the drug contains an insect repellent component (tick-proof component), the air (for example, indoor space) can be treated with insect repellent. It can be treated (tick-proof treatment); if the drug contains an insect repellent component, the atmosphere (for example, outdoor and indoor spaces) can be treated with insect repellent.

When the energization of the heating element is cut off (off), the heating state is released and the heating element reaches room temperature (its environmental temperature). By doing so, the vaporizer heated by the heating element in the heating state also returns to normal temperature (its environmental temperature), and its evaporation can be stopped. The one-time energization time is not limited, and examples thereof include a time during which a 1 to 5 mL volume of the transpiration solution evaporates and disappears after 60 times of energization (heating). This is the time during which the transpiration solution, preferably 1 to 3 mL in volume, more preferably 1 mL in volume, evaporates and disappears after 60 times of energization (heating). Although not limited, specifically, 60 to 600 minutes, preferably 300 to 400 minutes can be exemplified.

Hereinafter, an embodiment of the chemical transpirator of the present invention will be described with reference to the drawings.
<1. Overall configuration of chemical transpirator>
FIG. 3 is a perspective view showing the overall configuration of the chemical steamer A according to the present embodiment. As shown in the figure, the chemical transpiration device A is a chemical transpiration device that imitates an incense holder, and has a circular pot-shaped main body 10 and a pseudo incense stick 15 that is set upright on the main body 10. .. The pseudo incense stick 15 is not a real incense stick, but a plastic stick that imitates an incense stick. More specifically, it is an optical fiber made of acrylic resin, and a green film is attached to the surface except for the upper end portion 15a. This membrane is light opaque. Then, the LED light source 16 arranged in the main body 10 illuminates the lower end portion of the pseudo incense stick 15 also arranged in the main body 10 (see FIG. 14). As a result, only the upper end portion 15a of the pseudo incense stick 15 shines, and an appearance as if a real incense stick is burning can be obtained.

Further, the chemical evaporator A can also raise the smoke of the transpiration liquid agent, and in this sense as well, it can exert a function like an incense holder. The transpiration liquid agent can be a drug having a fragrance component, a deodorant component, an antibacterial component, an insect repellent component, and / or an insect repellent component, but in the present embodiment, a fragrance component having a burning odor of incense stick is used. Have.

The transpiration liquid agent is housed in a cartridge type container 40 set in the main body 10. FIG. 4 shows the main body 10 in a state where the flap member 20 that can be opened and closed by rotation, which is provided on the upper part of the main body 10, is opened. The container 40 can be set in the space S1 appearing in the center of the upper part of the main body 10 by opening the flap member 20, and can be taken out from here. FIG. 5 is a perspective view of the main body portion 10 in which the flap member 20 is omitted for reference, and FIG. 6 is a perspective view showing a state in which the vaporizer container 40 is housed in the central space S1 of the main body portion 10. Is. The flap member 20 is omitted in FIG. 6 for reference.

FIG. 7 is a perspective view of the container 40. The container 40 is provided with a dedicated cap 45 so that the transpiration liquid inside does not leak when not in use. Then, at the time of use, the cap 45 is removed (see FIG. 8) and set in the main body 10.

<2. Container part of chemical transpirator>
The configuration of the container 40 of the chemical transpirator A will be described in detail. FIG. 9 is a cross-sectional view taken along the line AA of FIG. 3 near the container 40. As shown in FIGS. 7 to 9, the container 40 has a container 41 having an open upper portion, and in order to stably support the container 41, the vicinity of the lower portion of the tubular side wall portion 42 of the container 41 is formed. It has a pedestal 43 that supports it from the outside of the container 41. A lid 50 that closes the opening is attached to the upper opening of the container 41. The lid 50 has a substantially flat bottom surface portion 51 and an outer peripheral wall 52 that stands up along the outer periphery of the bottom surface portion 51, and the bottom surface portion 51 and the outer peripheral wall 52 as a whole are dish-shaped dish portions. It constitutes 53. The bottom surface portion 51 defines the upper surface of the internal space S2 of the container 41. The container 41 is filled with the above-mentioned transpiration liquid agent.

A circular opening S3 is formed in the center of the bottom surface portion 51, and a tubular body 54 having an internal space communicating with the opening S3 is continuous on the lower surface of the bottom surface portion 51. The tubular body 54 is spaced from the bottom surface portion 44 of the container 41 at a certain interval, and extends substantially in the vertical direction. A core material 60 is inserted into the tubular body 54 so that the lower end 60a thereof substantially reaches the bottom surface portion 44 through the opening S3. On the other hand, the upper end 60b of the core material 60 projects from the bottom surface 51 of the lid 50 so as to come into contact with or approach the heating element 65 described later. The core material 60 is a rod having substantially the same cross-sectional shape as the cross-sectional shape of the opening S3 and the tubular body 54, and can be impregnated with the transpiration liquid agent in the container 41.

As shown in FIG. 8, in the bottom surface portion 51 of the dish portion 53, in addition to the opening S3 into which the core material 60 is inserted, an opening S4 communicating with the internal space S2 of the container 41 is formed. Although the details will be described later, a tunnel passage S5 where dew condensation of the heated and evaporated smoke-like transpiration liquid can occur is arranged above the bottom surface 51 of the dish 53. Therefore, the dish portion 53 can function as a member for receiving the liquid transpiration liquid agent that falls from the inside of the tunnel passage S5 after dew condensation occurs in the tunnel passage S5. The plurality of openings S4 of the bottom surface portion 51 function as a liquid return passage for returning the liquid transpiration agent received in the dish portion 53 to the internal space S2 of the container 41.

A spiral thread 42a is formed on the upper outer peripheral surface of the side wall portion 42 of the container 41. The screw thread 42a is screwed into a screw groove (not shown) formed in the cap 45 of the container 40, whereby the cap 45 is detachable from the container 40.

Further, a handle 46 is continuous with the pedestal 43 of the container 41. The handle 46 extends substantially parallel to the side wall portion 42 with a certain distance from the side wall portion 42, and extends above the core material 60 held by the lid 50. The handle 46 is used to carry the container 40 when the container 40 is housed in the space S1 provided in the center of the upper part of the main body 10.

The materials of the container 40 and the cap 45 are not particularly limited, but may be made of plastic, for example (excluding the core material 60). Each of the above-mentioned parts can be integrally formed in the container 40, or can be formed by combining different members.

<3. Body>
The main body 10 has a housing 11 that forms an outer wall shaped like an incense holder jar, and a space S1 for accommodating the container 40 is formed in the center of the upper part. Further, the main body 10 has a flap member 20 housed in the space S1 from above the container 40. The flap member 20 swings by rotation, and the space S1 can be opened and closed. The material of the housing 11 is not particularly limited, but may be made of plastic, for example.

FIG. 10 is a perspective view of the flap member 20 alone as viewed from the upper surface side, and FIG. 11 is a perspective view of the flap member 20 alone as viewed from the lower surface side. As shown in the figure, the flap member 20 has a rectangular parallelepiped shape, and a rotation shaft 21 for rotating the flap member 20 is provided at one end in the longitudinal direction in parallel with the lateral direction. As shown in FIG. 5, the space S1 has a shape in which a rectangular parallelepiped is superposed on the upper part of the cylinder so as to project in the radial direction from the cylinder. Further, the upper surface of the cylinder and the upper surface of the rectangular parallelepiped referred to here are substantially the same height, and the rectangular parallelepiped projects only in the longitudinal direction from the side surface of the cylinder and does not project in the lateral direction. The rectangular parallelepiped has substantially the same shape as the flap member 20, and the space S1 can receive the flap member 20 at a portion corresponding to the rectangular parallelepiped. Further, the housing 11 supports the rotation shaft 21 so as to rotate the flap member 20 up and down at a portion corresponding to one end of the rectangular parallelepiped in the space S1 in the longitudinal direction. Hereinafter, the state in which the flap member 20 is housed in the portion corresponding to the rectangular parallelepiped of the space S1 is referred to as a state in which the flap member 20 is closed. Further, on the upper surface of the flap member 20, a handle 22 projects from the end on the opposite side of the rotating shaft 21. The user can easily rotate the flap member 20 around the rotation shaft 21 by hooking a finger on the handle 22.

The space S1 communicates with the external space even when the flap member 20 is closed. That is, openings S7 and S7 (see FIG. 3) communicating with the space S1 are secured on both sides of the flap member 20. Further, a protrusion 24 projects from the end surface of the flap member 20 on the side opposite to the side on which the rotation shaft 21 is provided. On the other hand, in the main body portion 10, an elastic piece 23 for hooking the protrusion 24 is provided at a portion of the flap member 20 that receives a portion near the end surface (see FIG. 5). Then, when the flap member 20 is about to be closed, the protrusion 24 presses the elastic piece 23, and the elastic piece 23 is elastically deformed so as to bend outward in the radial direction. After that, when the flap member 20 is housed in the space S1, the elastic piece 23 substantially returns to its original shape due to its elasticity and presses the protrusion 24 from above. As a result, the flap member 20 is firmly fixed in the space S1 and locked in a closed state. On the other hand, even when an external force is applied to the flap member 20 by holding the handle 22 to rotate the entire flap member 20 upward, the elastic piece 23 is elastically deformed so as to bend outward in the radial direction, and the flap member 20 is elastically deformed. Can be easily opened.

At the center of the flap member 20, a tunnel passage S5 that substantially penetrates the flap member 20 in the vertical direction is formed. More specifically, in the center of the flap member 20, a cylindrical tunnel member 30 having openings at both ends that defines the tunnel passage S5 is embedded. The tunnel member 30 may be integrally formed with the rectangular parallelepiped housing of the flap member 20. Hereinafter, the opening at the lower end of the tunnel member 30 communicating with the tunnel passage S5 is referred to as a tunnel entrance 30a, and the opening at the upper end is referred to as a tunnel exit 30b.

A heating element 65 for heating the core material 60 and evaporating the transpiration liquid absorbed in the core material 60 in the form of smoke is arranged in the tunnel passage S5 (see FIG. 9). The heating element 65 is a heating wire that generates heat when energized, and is from a certain position on the inner wall surface 31 of the tunnel member 30 to another position on the inner wall surface 31 facing the heating element 65 (both positions are the tunnel member 30). It extends to (located on the diameter line of the circular cross section). The heating element 65 is arranged below the center in the vertical direction in the tunnel passage S5. Both ends of the heating element 65 are wired to the battery 8 described later. This wiring is housed in the flap member 20 and the housing 11 at a position that is not normally touched from the outside. With the above configuration, the tunnel passage S5 is a passage through which the smoke-like transpiration liquid generated by heating the heating element 65 passes through.

As shown in FIG. 11, a plurality of wall members 34 (four in the present embodiment) extend downward from the lower part of the tunnel member 30 so as to surround the tunnel entrance 30a. The lower ends of these wall members 34 accommodate the container 40 in the space S1 of the main body 10, and in a state where the flap member 20 is closed, come into contact with the bottom surface 51 of the dish 53 constituting the upper portion of the container 40. .. That is, the container 40 is arranged at a certain interval in the vertical direction from the tunnel entrance 30a, and the wall member 34 is arranged so as to extend between the tunnel entrance 30a and the container 40 in order to fill this interval. The container 40 is arranged directly below the tunnel entrance 30a, and the center of the bottom surface portion 51 of the container 40 and the center of the tunnel entrance 30a substantially overlap in a plan view. Further, the lower portion of the outer surface of the wall member 34 comes into contact with the inner peripheral surface of the outer peripheral wall 52 of the dish portion 53.

FIG. 12 is a bottom view of the vicinity of the tunnel member 30. As shown in FIGS. 11 and 12, the wall members 34 are arranged at equal intervals along the circumferential direction of the tunnel entrance 30a with a gap S6. The gaps S6 are open at equal intervals by the same length, and serve as an air suction port for sending air into the tunnel passage S5 via the tunnel entrance 30a. That is, since the space below the tunnel entrance 30a is surrounded by the wall member 34 and the dish portion 53 of the container 40 except for the gap S6, in principle, only the gap S6 is the air that takes in air into the tunnel passage S5. It becomes an intake port. The external air first flows into the space S1 in the main body 10 through the openings S7 and S7 formed at both ends of the flap member 20, and is sent into the tunnel passage S5 through the gap S6. ..

As shown in FIG. 12, a plurality of convex portions 32 protruding inward in the radial direction are formed on the inner wall surface 31 of the tunnel member 30 that defines the tunnel passage S5. These convex portions 32 are provided at different positions along the circumferential direction of the inner wall surface 31. In the present embodiment, the same number of convex portions 32 as the wall member 34, that is, four convex portions 32 are provided, and these convex portions 32 are arranged at substantially equal intervals along the circumferential direction of the inner wall surface 31. Further, the convex portion 32 continuously extends in the vertical direction from the same height position as the tunnel outlet 30b, passes through the tunnel entrance 30a, and slightly above the lower end of the wall member 34. Further, below the tunnel entrance 30a, the convex portion 32 is connected to the wall member 34, and in a plan view, the convex portion 32 projects inward in the radial direction from the center of the inner wall surface of the wall member 34. .. Further, the convex portion 32 extends from the inner wall surface 31 in the radial direction of the circular cross section of the inner wall surface 31 in a plan view, but does not reach the center of the circular cross section. Therefore, in the center of the tunnel passage S5, an open space extending in the vertical direction is formed without being disturbed by the convex portion 32.

The convex portion 32 configured as described above can prevent a finger from touching the heating element 65 in the tunnel passage S5. Further, in addition to this role, the convex portion 32 can play a role of raising the smoke-like transpiration liquid evaporated by heating by the heating element 65 to be thinner and higher. FIG. 13 is a schematic vertical cross-sectional view of the vicinity of the tunnel passage S5 for explaining the role of the convex portion 32. That is, in the tunnel passage S5, a gentle updraft is generated as the air is warmed by the heating element 65. Then, the smoke composed of the aerosol particles of the transpiration liquid generated by the heating element 65 heating the upper end 60b of the core material 60 rises while passing through the tunnel passage S5 on this updraft. , Collides with the inner wall surface 31 and also collides with the convex portion 32. As a result, the transpiration liquid condenses on the surfaces of the inner wall surface 31 and the convex portion 32, and droplets adhere to the surface. The amount of droplets, that is, aerosol particles, increases as the evaporation of the evaporative solution progresses, and as a result, the droplets of the evaporative solution agent adhering to the surfaces of the inner wall surface 31 and the convex portion 32 cause the evaporative solution agent to adhere. The tunnel passage S5 for the smoke to pass through is substantially narrowed. As a result, the velocity of the updraft increases, and the evaporated transpiration agent rises finer and higher. Further, since the convex portion 32 is continuous in the vertical direction in the tunnel passage S5, it is easy for air to flow straight upward. That is, for example, when the convex portion 32 is interrupted in the middle, the airflow bends at the interrupted portion of the convex portion 32, but such a situation is avoided in the present embodiment.

By the way, the above-mentioned updraft is formed by the air flowing in from the above-mentioned gap S6. Further, as described above, the presence of the wall member 34 narrows the air intake port into the tunnel passage S5, and the air intake port is mainly only the gap S6. Therefore, a higher speed air flow flows into the tunnel passage S5 through the gap S6 as the narrowed air suction port, resulting in a finer and higher rise of the evaporated smoke-like transpiration liquid. Further, due to the presence of the wall member 34, the tunnel through which the evaporated transpiration agent passes is substantially extended. As a result, the chimney effect is promoted and the evaporated transpiration agent rises higher.

The gaps S6 are provided at four locations, and the area per one is preferably 2 mm ^{2 to} 40 ^{mm 2} , more preferably 4 mm ^{2 to} 30 ^{mm 2} , still more preferably 4 mm ^{2 to} 20 ^{mm 2} , still more preferably 5 mm ^2. ~ 15 mm ² . The gap S6 referred to here is an area surrounded by a tunnel member 30 on the upper portion, a pair of wall members 34 on the left and right sides, and an outer peripheral wall 52 of the dish portion 53 on the lower portion. On the other hand, space S7, has provided two positions, the area per one is preferably 150 mm ² to 300 mm ^2, more preferably 200 mm ² to 300 mm ^2. The space S7 referred to here is an area surrounded by the flap member 20 on the inside and the upper surface 13 of the housing 11a on the outside. Further, the tunnel inlet 30a and the tunnel outlet 30b (i.e., the inner cross-sectional shape of the wall 31 of the tunnel member 30) (including the convex portion 32) area is preferably 20mm ² ~180mm ^2, more preferably 50mm ² ~120mm ² , even more preferably 50 mm ² 100 mm ^2. First, external air flows into the space S1 in the main body 10 through the openings S7 and S7 formed at both ends of the flap member 20, and this is sent into the tunnel passage S5 through the gap S6. As a result, the wind speed gradually increases from the external space to the space S1 via the space S7, and then from the space S1 to the tunnel member 30 via the gap S6. Further, smoke is emitted from the inside of the tunnel member 30 to the outside space through the tunnel outlet 30b at a wind speed of a certain level or higher. When each area is in the above numerical range, the effect can be further exerted.

Further, the size of the particles of the transpiration liquid generated in the tunnel passage S5 varies in size, but the smaller the particles, the faster the particles can flow and the higher the particles can rise. Also, the larger the particles, the easier it is to see. Then, as shown in FIG. 13, smaller particles collide with larger aerosol particles and exert an upward force on them, so that even these larger particles can rise higher. Therefore, the easily visible smoke containing large aerosol particles rises finer and higher.

Further, as described above, the particle size of the aerosol of the transpiration liquid adhering to the surfaces of the inner wall surface 31 and the convex portion 32 increases as the evaporation of the transpiration liquid progresses, and gradually grows. Then, the enlarged droplets of the transpiration liquid fall along the inner wall surface 31, the convex portion 32, and the wall member 34 according to gravity, and are received by the dish portion 53. The liquid transpiration liquid accumulated in the dish portion 53 is returned to the internal space S2 of the container 40 through the opening S4 of the bottom surface portion 51. Therefore, various problems such as stains caused by dew condensation of the transpiration solution and waste of the transpiration solution are solved.

Returning to FIG. 5, the lower surface of the space S1 of the main body 10 described above is defined by a saucer 55 that can be raised and lowered in the vertical direction. The saucer 55 is substantially equal to the outer shape of the lower part of the container 40, and defines a space in which the saucer 55 can be accommodated. FIG. 14 is a cross-sectional view taken along the line BB of FIG. As shown in the figure, the raising and lowering of the saucer 55 is realized by the spring 56 connected below the saucer 55. When the saucer 55 receives an external force from above, the spring 56 contracts and the saucer 55 moves downward. When the flap member 20 is closed with the container 40 housed in the saucer 55, the saucer 55 is pushed by the container 40 and moves downward. At this time, the spring 56 urges the saucer 55 upward by the restoring force, and as a result, the container 40 is urged against the tunnel member 30 via the wall member 34. As a result, the bottom surface portion 51 of the dish portion 53, the outer peripheral wall 52, and the wall member 34 are firmly fitted, and the position of the container 40 in the space S1 is stabilized. Further, as a result, a gap other than the gap S6 is less likely to occur as an air suction port communicating with the tunnel passage S5 below the tunnel entrance 30a.

By the way, the housing 11 can be divided into two upper and lower housings 11a and 11b along the dividing line L1 shown in FIG. FIG. 15 is a view of the upper housing 11a as viewed from the bottom surface side. As shown in the figure, a battery accommodating portion 80 to which two batteries 8 can be attached is provided on the outside of the bottom surface portion of the upper housing 11a.

FIG. 15 is a block diagram showing an electrical configuration of the chemical evaporator 1. As shown in the figure, the battery 8 is electrically connected to the heating element 65 and the LED light source 16 to supply electric power to them. As shown in FIG. 14, the LED light source 16 is arranged in the housing 11a directly below the opening S8 that receives the pseudo incense stick 15. Further, the control board 18 connected to the switch 17 is also housed in the upper housing 11a. As shown in FIG. 3, a switch 17 is arranged on the upper surface 13 of the housing 11a, and when the switch 17 is pressed, a signal to that effect is sent to the control board 18. Further, a detection circuit 19 for detecting that the spring 56 has been pressed is connected to the control board 18. When the control board 18 detects that the spring 56 is in a pressed state (the container 40 is set in the space S1 and the flap member 20 is closed) and the switch 17 is further pressed in the power-off state. , The battery 8 supplies power to the heating element 65 and the LED light source 16. On the other hand, when the switch 17 is pressed or the pressed state of the spring 56 is released in the power-on state, the power supply from the battery 8 to the heating element 65 and the LED light source 16 is stopped.

As shown in FIG. 3, the upper surface 13 of the housing 11 is formed in an annular shape so as to define the space S1. On the front side of the upper surface 13, three openings S8 for inserting the pseudo incense stick 15 are formed. On the other hand, the switch 17 is arranged on the upper surface 13 of the housing 11 on the side substantially 180 ° opposite to the opening S8. On the annular upper surface 13, an outer wall portion 14 stands up along the outer peripheral edge thereof. The outer wall portion 14 is a portion that defines the edge of the upper opening of the pot-shaped housing 11. The upper surface 13 of the housing 11 is located in substantially the same plane as the upper surface of the flap member 20 in the closed state, in other words, is arranged at the same height as the tunnel exit 30b. Therefore, the outer wall portion 14 acts as a windshield against the smoke rising from the tunnel outlet 30b, and helps the smoke to rise straight and thin. Further, although the outer wall portion 14 is formed substantially once and continuously along the upper surface 13 of the housing 11, the outer wall portion 14 is notched at a position facing the switch 17 so as not to interfere with the operation of the switch 17. It has been done. Further, even if the chemical evaporator 1 is turned over and turned upside down, the outer wall portion 14 prevents the switch 17 from malfunctioning.

FIG. 17 is a bottom view of the chemical evaporator A. As shown in the figure, the housing 11 is provided with three legs 29 at equal angular intervals around the central axis of the housing 11. One of these three legs 29 is located around the central axis of the housing 11 at the same angle as the switch 17. In FIG. 17, the position of the switch 17 is shown by a dotted line for reference. By the way, when the switch 17 is pressed, a non-uniform external force is applied to the housing 11 around the switch 17. However, according to the above configuration, since the legs 29 corresponding to the switch 17 firmly support the housing 11, the chemical evaporator A does not fall over.

In the above, the wall member 34 is integrally formed with the tunnel member 30, but is not formed with the tunnel member 30, but is integrally formed with the container 40 side, for example, the outer peripheral wall 52 of the dish portion 53. May be good. Alternatively, the wall member 34 may be a component independent of both the tunnel member 30 and the container 40.

Further, the shape of the convex portion 32 is not limited to that described above. For example, the convex portion 32 may have a shape that ends from the vicinity of the tunnel exit 30b to the vicinity of the tunnel entrance. Further, the number of the convex portions 32 is not limited to four, and may be one, for example. Further, as shown in FIG. 18A, the convex portion 32 may reach the center of the tunnel passage S5 in a plan view, and in this case, the plurality of convex portions 32 may intersect at the center. .. Further, as shown in FIG. 18B, it may be in a grid pattern in a plan view. However, in the form of FIGS. 18A and 18B, since the tunnel passage S5 is divided into a plurality of passages, the passage may be partially filled by dew condensation. Therefore, from the viewpoint of raising a single thin and long smoke, the form shown in FIG. 12 is preferable.

<3. How to use>
Hereinafter, a method of using the chemical evaporator A will be described. First, a main body 10, a container 40, and a pseudo incense stick 15 constituting the chemical transpirator A are prepared. Then, the flap member 20 of the main body 10 is rotated to open the space S1, the handle 46 is gripped, the container 40 is inserted, and then the flap member 20 is closed. At this time, in the tunnel passage S5 of the flap member 20, the core material 60 of the container 40 is arranged so as to be in contact with or close to the heating element 65. Further, the pseudo incense stick 15 is inserted into the opening S8 of the upper surface 13 of the main body 10.

After that, when the switch 17 is pressed, the heating element 65 and the LED light source 16 are energized, the heating element 65 is heated, and the LED light source 16 is turned on. The light from the LED light source 16 propagates in the pseudo incense stick 15 and reaches the upper end portion 15a to generate colored light. Further, after a while after pressing the switch 17, the transpiration liquid impregnated in the core material 60 is heated, and a smoke-like transpiration liquid agent visible from the upper end 60b of the core material 60 begins to be generated. This smoke rides on the flow of air that has flowed into the tunnel passage S5 through the gap S6 formed between the container 40 and the wall member 34, and begins to rise long and thin upward. After a while, dew condensation of the transpiration liquid agent begins to occur in the tunnel passage S5. The droplets grow on the inner wall surface 31, the convex portion 32, and the surface of the wall member 34 of the tunnel member 30, and substantially narrow the tunnel passage S5, thereby causing the updraft generated in the tunnel passage S5. Increase speed. In response to this, the smoke coming out of the tunnel exit 30b will rise up more and more thinly and long.

In addition, a part of the droplet that has grown large in the tunnel passage S5 falls according to gravity. The dropped droplets of the transpiration liquid are received by the dish portion 53 on the upper part of the container 40, move into the container 40 through the opening S4, and are sucked up by the core material 60 again.

From the above, the chemical transpiration device A can be used as a pseudo incense holder. In particular, it is excellent in safety in that the light, smoke and scent of incense sticks can be realized without using fire.
