【Example】

 A first embodiment of the heating evaporation device according to the present invention will be described. As shown in FIG. 1, the apparatus main body 1 has a hollow shape with an upper main body 2 and a lower main body 3, and the upper main body 2 has a cylindrical peripheral wall whose upper side is gradually reduced in diameter from bottom to top. 4 and an upper wall 5 provided over the entire upper end of the peripheral wall 4 are opened downward. Further, the upper wall 5 is provided with a transpiration hole 6 at the center thereof. The lower main body 3 has a cylindrical peripheral wall 7 whose upper end is fitted to the lower end of the peripheral wall 4 of the upper main body 2, an annular bottom wall 8 integrally provided inside the upper end of the peripheral wall 7, and a bottom wall 8 of the bottom wall 8. A substantially cylindrical shape in which the center is opened vertically from the inner peripheral wall 9 consisting of a lower large-diameter cylindrical body 9a standing upright from the inner peripheral end and an upper small-diameter circular cylindrical body 9b standing upright from the upper part of the lower large-diameter cylindrical body 9a. It has become. Further, a ventilation hole 10 communicating from the lower side to the upper side is provided in a part of the lower large-diameter cylindrical body 9a of the inner peripheral wall 9 of the lower main body 3, and the bottom wall 8 and the lower large-diameter cylindrical body 9 of the inner peripheral wall 9 are provided. A plurality of heating element support portions 11 are erected at positions extending over 9a. Further, the lower main body 3 is provided with a plurality of legs 12 projecting downward at equal intervals in the circumferential direction at the lower end of the peripheral wall 7 thereof, so that when the apparatus main body 1 is installed, the lower end portion is provided by the legs 12. A gap is formed in the air gap, and an air intake port is formed so that air can be taken into the apparatus main body 1 through this gap. In addition, a screw portion 14 that is screwed into a container 13 for containing a liquid medicine is formed on the inner periphery of the upper small-diameter cylindrical body 9b of the inner peripheral wall 9 of the lower body 3, and the container 13 is arranged from the lower part to the lower large-diameter cylindrical body. 9a and the small-diameter upper cylindrical body 9b are inserted into a storage portion 15 formed inside, and the screw portion 13a of the container 13 is screwed and held to the screw portion 14. The container 13 has a liquid medicine stored therein and is provided with a liquid absorption core 18a as a heated body 18 for sucking and impregnating the medicine so as to project upward. The heating element 16 is fixed to the upper end of the heating element support portion 11 provided in the lower main body 3 via the mounting plate 17 and surrounds the liquid absorbent core 18a provided in the container 13 with a gap. It has a ring shape. In addition, a cylindrical heat radiating portion 19 that surrounds the liquid absorbent core 18a with a gap is also provided on the inner circumference of the heat generating element 16, and the heat radiating portion 19 of the heat generating element 16 is provided. It is configured so as to project upward from the upper end and the upper end thereof is close to the lower end of the peripheral edge of the evaporation hole 6 provided in the upper wall 5 of the upper body 2.

When the cord is plugged into a power outlet in this state and energized, at the same time, the heat-generating body 16 generates heat, and the heat radiating section 19 generates heat due to conduction heat and radiant heat to heat the upper part of the liquid absorbent core 18 a and heat the container 13 The medicine sucked from the inside is evaporated, and the medicine is evaporated from the evaporation hole 6 through the internal space of the heat dissipation portion 19. At this time, a heat rising airflow is generated by the heat generation of the heating element 16 described above, and the air flows in the apparatus body 1 as described below. The outside air flows into the inside of the device body 1 from the lower part of the device body 1 through the gap of the vent hole 10 or the screw part 14 provided in the lower body 3, and first, through the internal space of the heat dissipation part 19 to the evaporation hole 6, Secondly, it flows into the evaporation hole 6 through the vicinity of the outer periphery of the heating element 16 and the heat dissipation portion 19, and thirdly, into the evaporation hole 6 through the vicinity of the peripheral wall 4 of the upper body 2.

In the heating evaporation device, when the evaporated drug is generally contained in the device body 1 or an object (wall) having a low temperature is present in the evaporation path of the drug, the drug comes into contact with the object. The drug condensation phenomenon easily occurs, and the drug contamination inside the apparatus main body 1 easily occurs. However, in the heating and vaporizing apparatus according to the present invention, the heat radiating portion 19 is heated by the heat generating element 16 and is always kept warm by the rising airflow along the outer periphery of the heat radiating portion 19, and the inside thereof is the heat generating element The rise in heat of 16 makes the ventilation from below smooth, so that the evaporated chemicals do not adhere. Further, by providing the heat radiating portion 19, the heat rising airflow generated from the heating element 16 becomes an airflow rising toward the evaporation hole 6 along the outer circumference of the heat radiating portion 19 and hits the upper body 2 in the device body 1. Also, it has an effect of preventing the generation of turbulent flow inside the device body 1 caused by a cross wind from the outside. In this way, the evaporation trajectories of the evaporated chemicals are regulated by the heat-dissipating portion 19 and guided to the evaporation holes 6, thereby preventing the chemicals from adhering to or adhering to the inside of the apparatus main body 1 from contaminating the apparatus main body 1, and by extension, The desired transpiration effect can be obtained by improving the transpiration rate.

Here, the temperature at which the drug does not easily adhere varies depending on the type of the drug. For example, when the drug is used as an electric mosquito trap, an aliphatic hydrocarbon solvent is mixed with allethrin dl-3-ally1-2. -Methy1-4-oxo-2-cyclopentenyl dl-cis / trans-chrysanthemate Resmethrin (5-benzy1-3-fury1) methy1 dl-cis / tran nsyl- chrysanthelate phenothrin 3-phenoxy-enoxylate. [5- (2-propyny1) -2-fury1] methy1 dl-cis / trans-chrysanthemate pralethrin (s) -2-m thy1-4-oxo-3- (2-propyny1) cy clopent-2-eny1 (1R) -cistrans-chrysane hemate permethrin 3-phenoxybenzy1 dl-cis / trans-3- (2,2-dichloroviny1) -2. -Dimethycyclopropanecarboxylate benfluthrin [(Pentafluorophenyl1) -methy1] -1R, 3R-3- (2,2-dichloro-ethyny1) -2,2-dimethyropropenecide etc. Then, it is preferable to keep the temperature of the protruding portion of the heat dissipation portion 19 at 70 ° C. or higher, and more preferably 100 ° C. or higher.

Further, it is desired that the material of the heat radiating portion 19 also has heat resistance and chemical resistance depending on the kind of the agent to be evaporated, and for example, polypropylene, polyethylene, polyamide, polyethylene terephthalate, polybutylene terephthalate, Polysulfone, polyacetal, melamine resin, polytetrafluoroethylene, phenolic resin, unsaturated polyester resin, epoxy resin, urethane resin, methacrylic acid resin, polyacrylate, polyketone, polyamideimide, polyallylsulfone, polyphenyl Resins such as rensulfite, polyphenyl sulfone, and polyether nitrite can be used, but when used as an electric mosquito trap, when the protruding part of the heat dissipation part 19 is kept at a high temperature (for example, 70 ° C or higher), The heat dissipating part 19 is made of a heat conductive material. For example, silver, copper, gold, aluminum, duralumin, brass, tungsten, iron, stainless steel, brass and other metals, aluminum oxide, silicon oxide, magnesium oxide, beryllium oxide and other ceramics, etc. The temperature of the heat radiating portion 19 can be arbitrarily set depending on the type of the drug that can be used and is evaporated.

Further, in order to obtain a smooth drug evaporation effect without turbulence inside the apparatus main body 1, the distance between the upper end of the heat radiating portion 19 and the lower end of the peripheral edge of the evaporation hole 6 is shortened, that is, close to less than 5 mm. Alternatively, it is most preferable to provide them closely. Further, the heat radiating portion 19 is formed in a cylindrical shape so as to project upward from the upper end surface of the heat generating element 16, and the spatial distance between the heat generating element 16 and the upper wall 5 of the upper main body 2 located above the heat generating element 16. Since it can be made large, and most of the heat rising airflow rises along the protruding portion of the heat dissipation part, collision of the heat rising airflow around the evaporation holes is suppressed and excessive heat rise of the upper main body 2 is prevented. Therefore, the structure is such that even if the upper body 2 is touched during transportation, no burns are caused, and the evaporated chemical can be evaporated from the evaporation hole 6 to the outside of the apparatus main body 1 without waste.

Next, the second embodiment will be described. As shown in FIG. 2, the heating element 16 is provided at an eccentric position with respect to the liquid absorption core 18 a provided in the container 13, and the heating element 16 A cylindrical heat radiating portion 19 which surrounds the liquid absorbent core 18a with a gap is provided in a part thereof. A cylindrical guide heater portion 25 is fitted to the upper end portion of the heat radiating portion 19, and the upper end portion of the guide heater portion 25 is inside the evaporation hole 6 provided in the upper wall 5 of the upper body 2. It is arranged so as to be close to the annular heat receiving portion 20 which is integrally formed and whose inner peripheral side is higher. In the inside of the apparatus main body 1, the container 13 and the housing portion 15 are not fitted to each other by providing threaded portions to each other, but are fitted to the inner peripheral lower end portion of the peripheral wall 7 of the lower body 3 inside. A projecting fixing rib 21 is formed, and a container receiving member 22 for holding the lower end of the container 13 in contact with the fixing rib 21 is fitted into the fixing rib 21. In addition, the container receiving member 22 is provided with a vent hole 23 that communicates in the vertical direction.

As described above, when the heating element 16 is provided at a location eccentric to the liquid absorption core 18a of the container 13, in general, due to its structure, it is vaporized by an ascending air current generated from the heating element 16. While the medicine is rising, it is pulled above the heating element 16 and evaporated to a position deviated from the center of the liquid absorbent core 18a. Therefore, if the evaporation hole 6 is not formed to be considerably large, the evaporated drug collides with the periphery of the evaporation hole 6 of the apparatus main body 1 to generate a turbulent flow, so that the evaporated drug may be trapped inside the apparatus body 1 or It was attached and polluted, and further, it was a cause that the desired drug evaporation effect was not obtained. However, in the present invention, by providing the guide heater part 25, the evaporative agent is guided by the ascending airflow in the guide heater part 25 to the evaporative hole 6, whereby the evaporative passage can be regulated. In both cases, the guide heater portion 25 is kept at a constant temperature by the conduction heat from the heating element 16, and is further kept warm by the upward thermal air flow toward the evaporation hole 6 along the outer periphery of the guide heater portion 25, Even if the evaporated drug comes into contact with the evaporated drug, the drug does not adhere and can be smoothly evaporated from the evaporation hole 6. Further, since the heat-upflow air from the heating element 16 generated on the outer circumference of the guide heater portion 25 does not become a turbulent flow in the vicinity of the evaporation hole 6 but wraps around the evaporated drug, it is condensed and evaporated. Also, the effect of side winds is small, and the desired stable drug evaporation effect can be obtained. That is, even in the case where the heating element 16 is provided at a position eccentric with respect to the liquid absorbent core 18a, stable drug evaporation can be performed.

Further, in the third embodiment, as shown in FIG. 3, the heat radiation portion 19 is formed into a cylindrical shape whose diameter is gradually reduced toward the evaporation hole 6 to evaporate in the same manner as the above-mentioned embodiments. The chemicals are not attached to the heat radiating section 19 and can be stably evaporated by being guided to the transpiration hole 6 along the inner circumference of the radiating section 19, and the diameter of the transpiration hole 6 can be reduced. This makes it easier to prevent foreign matter from entering through the transpiration hole 6 and prevent an infant from accidentally putting his or her finger on a burn and injuring it, thus improving safety. Further, in the present embodiment, a double heat receiving part 20 is provided in the evaporation hole 6 of the upper main body 2 so as to suppress the temperature rise outside the body of the upper main body 2, and the heat rise from the periphery of the heat receiving part 20. An air flow is generated to allow smooth chemical evaporation.

The part 25 is inserted into the evaporation hole 6 of the upper main body 2 from above, and a part of the peripheral part of the evaporation hole 6 is sandwiched between the protrusion 26 and the burr claw 27 at the upper part of the guide heater part 25, and In the above, it is configured to be fitted to the upper end portion of the inner circumference of the heating element 16.

Further, as a seventh embodiment, as shown in FIG. 7, the upper and lower sides of the cylindrical guide heater portion 25 fitted to the upper end portion of the heat radiating portion 19 are vertically ventilated. The slit portion 24 for use is formed.

In addition, as an eighth embodiment, as shown in FIG. 8, a plurality of inwardly projecting upper end portions of a cylindrical guide heater portion 25 fitted to the upper end portion of the heat radiating portion 19 are provided. A rib 28 is formed to prevent foreign matter from entering the inside of the apparatus main body 1 through the evaporation hole 6 by the rib 28.

In addition, as a ninth embodiment, as shown in FIG. 9, a heat receiving portion 20 is formed in the evaporation hole 6 of the upper main body 2, and a cylindrical guide heater portion 25 fitted into the heat receiving portion 20 is provided. The guide heater portion 25 has a structure in which the lower end portion is close to the heating element 16 and a protruding portion 29 protruding toward the outer periphery is formed so that the radiant heat from the heating element 16 is received by the protruding portion 29. There is.

Further, on the upper surface of the upper wall 5 of the upper main body 2, a plurality of rib bodies 30 projecting upward at equal intervals in the circumferential direction are integrally formed on the outer periphery of the evaporation hole 6, and the periphery of the evaporation hole 6 is directly touched. Do not touch.

Next, as another example, a description will be given of a case in which an impregnated body 18b preliminarily impregnated with a drug is used instead of the liquid absorbent core 18a in the heated body 18 provided in the container 13. As shown in FIG. 11, in the container 13, a holding body 31 is provided in an inner intermediate portion, and an impregnating body 18b preliminarily impregnated with a chemical is provided as the heated body 18 on the holding body 31.

[Effect of device]

 By disposing a heat dissipation part or guide heater part close to or in close contact with the evaporation hole on the upper wall inside the main body of the device, chemicals that evaporate due to the heat rising airflow generated by the heating element inside the heat dissipation part or guide heater part. Can be smoothly moved to the evaporation hole through the heat dissipation part or the guide heater part, and if there is a slight gap when the heat dissipation part or the guide heater part is close to the evaporation hole, the evaporated chemical will be in the heat rising air stream. By this, it is possible to always go to the evaporation hole without flowing into the internal space of the device body. In addition, a heat rising air stream is generated by the heating element along the outer circumference of the heat radiating portion or the guide heater portion, and the medicine evaporated from the heat rising air stream is wrapped up to prevent the medicine from flowing into the internal space of the device body. You can also do it. In this way, the evaporated drug is always directed to the evaporation hole to evaporate outside the device main body, so that the drug can be prevented from staying inside the device main body and adhering, and the desired stable drug evaporation can be achieved. The effect is obtained. In the heat radiating part or guide heater part, usually, when the drug evaporated by heating comes into contact with a cold wall and is rapidly cooled, drug coagulation occurs and drug adhesion occurs, but when it contacts the hot part. Since the above-mentioned adhesion phenomenon does not occur, even if the medicine contacts the heat radiating portion or the guide heater portion, the medicine does not adhere because the heat radiating portion or the guide heater portion is hot. Further, since the evaporated chemical liquid passes through the heat radiating part or the guide heater part, the structure of the heat radiating part or the guide heater part can be modified to design the transpiration path of the drug in the main body to some extent. Since the diameter of the evaporation hole can be reduced to some extent, foreign matter can be prevented from entering the device body through the evaporation hole, and at the same time, it is possible to prevent infants from accidentally inserting their fingers and getting burned. There is also an effect that the safety can be improved.
