First and second lower mounting legs 32, 33, a plurality of supporting projections 34 integrally provided on the upper surface of the main body 31, and upper mounting pieces integrally provided on the upper part of the first lower mounting leg 32. The main volatilization hole 30 is provided with a pair of fin pieces 36, 36 that face each other in the radial direction and integrally face downward, and the first lower mounting leg 32 is connected to the connecting wall of the lower body 2. 6 is supported by the first protection part support base 37, the second lower mounting leg 33 is supported by the second protection part support base 38 provided in the heating element support part 13, and the support projections 34 of the crown part 21 are supported. It is in contact with the lower surface, and the upper mounting piece 35 is supported by the lock receiving portion 39 provided on the lower surface of the crown portion 21 for protection. The portion 24 is attached such that the main volatilization hole 30 is concentric with the volatilization hole 28, is below the volatilization hole 28, and covers the upper portion of the heating element 23, and between the opposite end portions of the pair of fin pieces 36, 36. The distance L is smaller than the inner diameter d ₁ of the heat dissipation portion 26. The bottle 40 is provided with a liquid absorbent core 41 as a heated body 45 impregnated with a drug, and the bottle 40 is mounted in the bottle housing portion 9 so that the bottle lower surface 40a elastically contacts the bottle locking hook 17 and a supporting protrusion. The absorbent core 41 is held in contact with the pieces 14 and 15 and the bottle supporting portion 16, and the liquid absorption core 41 faces the inside of the heat radiating portion 26 through the vent holes 12 and 27, and between the pair of fin pieces 36 and 36 facing each other. The interval L is smaller than the outer diameter d ₂ of the liquid absorbent core 41.

By turning on the lamp 42 attached to the inner cylinder 5 at the lower part of the first lower mounting leg 32, the main volatilization hole You can light up around 30. 43 is a slit for illuminating the bottle from the lamp 42, and 44 is a ventilation hole formed in the connecting wall 6.

Next, the method of use and operation will be described. A bottle 40 having a liquid absorption core 41 partially immersed in a chemical solution is attached to a bottle locking hook 17 integrally provided on the bottom of the apparatus body 1 from the bottom of the front side of the apparatus body 1 as shown in FIG. Mounting. At this time, the bottle 40 is fixed and supported by the bottle support 16 and the support projections 14 and 15 so that the liquid absorption core 41 is located at the center of the heating element heating section, that is, the center of the heat radiation section 26. When the energization is started from the above-mentioned state, the lamp 42 is turned on, and the light is guided toward the protection section 24 integrated with the fin piece 36 made of a light-transmissive material which is molded as a separate member from the upper main body 3 and energized. You can check the existence of. Further, the bottle 40 is illuminated by the light leaked from the slit 43 provided in the lower main body 2, and the liquid level confirmation effect is obtained by the illumination of the liquid level inside the bottle. Further, the light emitted from the inside of the volatilization hole 28 allows the evaporation of the medicine to be visually observed, and has an illumination effect by being illuminated through the protection portion 24 that integrally glows with the fin piece 36 and the bottle 40. By heating the heating element 23, the liquid absorbent core 41 is heated and the medicine is volatilized, and at the same time, the fin piece 36 and the protective portion 24 are heated by the heat rise and conduction heat of the heating element 23. That is, an air flow as shown by the arrow in FIG. 1 is generated.

Next, the effect of the embodiment will be described. The fin piece 36 prevents foreign matter from entering the heating element heating portion from the outside inside the volatilization hole 28 and inside the main volatilization hole 30 in the central portion. For example, it functions as a safety mechanism so that an infant does not put his / her finger through the main volatilization hole 30 in the central portion and directly touch the liquid absorbent core 41 and the heating element heating portion to prevent burns or licking of chemicals. Since the fin piece 36 and the protection portion 24 are provided inside the volatilization hole 28 and between the volatilization hole 28 and the heating element 23, the heat radiated from the heating element 23 rises to the fin piece 36 and the protection portion 24. Most of the heat radiated from the heating element 23 is absorbed by the fins 36 and the protective portion 24 because they collide with each other and then rise further, and these become hot, and the periphery of the protective portion 24 (for example, the upper surface) also becomes warm due to conductive heat. As a result, the heat rising effect causes a natural heat updraft. The heated and volatilized drug volatilizes from the periphery of the heating element heating part by its own heat rising airflow, and the above heat rising airflow by the fin pieces 36 and the protection part 24 is also added, and further around and above the heat generating element 23. Volatilization is promoted by the air flow, passes through the main volatilization hole 30 in the central portion, and rises and volatilizes from the volatilization hole 28, so that the volatilization of the drug is smooth and the drug does not remain inside the apparatus main body 1. Since the protective portion 24 is provided one step lower than the volatilization hole 28, even if a side wind blows, the side wind is unlikely to hit the protection portion 24 directly, is not cooled, and the drug attachment phenomenon is unlikely to occur. Further, at least a double heat rising airflow is generated from the center and the surrounding ventilation portion of the protection portion 24, and becomes a double heat rising airflow from the volatilization hole to the outside air, so that a side wind or turbulence of the atmosphere occurs. Also, since the effect on volatilization is significantly suppressed, good drug volatilization can be obtained. As described above, the volatilized drug does not adhere to the inside of the apparatus body and is not easily contaminated, and the drug can be effectively volatilized without loss of the drug, and a sufficient effect can be expected with a predetermined drug. Further, since the protection portion 24 absorbs a large amount of heat, the temperature of the crown portion 21 on the upper surface around the volatilization hole 28 does not rise so much, the heating is prevented, and the risk of burns is reduced, so that the safety is improved. That is, the Electrical Appliance and Material Control Law stipulates that the outer surface temperature of the outer shell is 70 ° C or less for an electric fumigation pesticide that uses 100V electricity, for example. Therefore, it is necessary to increase the distance between the crown portion and the heating element, or a heat receiving portion is provided to maintain the temperature of 70 ° C. or lower. In the case of the former, the size of the device is increased, and in the case of the latter, the height of the device is suppressed, but the distance between the ventilation part in the central part and the heating part of the heating element is shortened, and the finger is not used in actual use. There was a risk of getting burned by putting it in. In the present invention, it is possible to easily maintain a temperature of 70 ° C. or lower, improve safety in actual use, and reduce the height of the main body of the device.

Further, the first lower mounting leg 32 extending in the longitudinal direction of the protective portion 24 from the first protective portion support base 37 is made substantially vertical and thick so that external force from above can be easily transmitted downward. , Acts to suppress damage from pressure from above, such as stepping on. In addition, since the protective portion 24 and the fin piece 36 are molded of a light-transmissive material, and the inside of the volatilization hole 28 can be made to shine by guiding light from the lamp 42, the volatilization hole 28 right above the heat-generating body can be used especially at night. Can be recognized, and functions together with the fin piece 36 so that, for example, when the apparatus main body is moved, a finger is not accidentally put and burned. Further, the light emitted from the volatilization hole 28 strikes the evaporated chemical, and only the passage of the light flux is scattered light, so that it appears to shine uniformly. Further, by lighting up from around the volatilization hole 28, the above-mentioned Tyndall light is generated upward from the apparatus main body 1, and the illumination effect is also improved. Further, since the evaporation of the medicine is visible, it is possible to confirm the flow of the outside air in the used space from the movement of the particles of the evaporation agent, and if the apparatus body 1 is placed on the windward side, a sufficient effect of the medicine can be exhibited. Further, the evaporated drug particles can be confirmed, and it can be recognized that the drug solution in the bottle 40 is exhausted. The bottle 40 is held by the bottle locking hook 17, the support projections 14 and 15, and the bottle supporting portion 16 which are integrally provided on the bottom of the apparatus body 1, and the bottle locking hook 17 is moved upward from the bottom of the bottle by the force of the bottle 40. Since it holds the bottle, it can be removed by simply sliding it forward while holding the bottle body, and does not require excessive force. In addition, it is a one-touch attachment / detachment method that requires only a light slide when mounting the bottle. Furthermore, the number of parts is small and the cost is reduced. Since the bottle 40 is almost completely exposed from the notch 8, it is easy to check the remaining amount of the chemical liquid in the bottle 40, the heat emitted from the heating element 23 has little influence, and the rising airflow causes The temperature rise inside the bottle can be suppressed and the leakage of the chemical liquid from the absorbent core due to the increase in internal pressure can be prevented. Moreover, the bottle 40 is illuminated by the light leaked from the slit 43 provided in the lower main body 2, so that it is easy to confirm the amount of liquid in the bottle at night, and the illumination effect is improved.

The protection part 24 is attached by being engaged with the mounting recess 58 of the part 21 and sandwiching the crown part 21 and the heating element 23. As shown in FIGS. 15 and 16, the protective portion 24 is provided integrally with the crown portion 21 by a plurality of bridges 59, and the fin piece 36 is made to project downward from the periphery of the main volatilization hole 30 in the central portion. As shown in FIGS. 17 and 18, a tubular body 60 is integrally provided on the protective portion 24, a hook 61 is provided on the lower portion thereof, and a support portion 62 is provided on the upper portion thereof to heat the protective portion 24 (fins 36). Attach to body 23. As shown in FIGS. 19 and 20, a plurality of fin pieces 36 (protection portions 24) are integrally provided downward at the lower portion of the periphery of the volatilization hole 28 of the crown portion 21. As shown in FIG. 21 and FIG. 22, the fin piece 36 has a ring shape and is integrally provided below the peripheral edge of the main volatilization hole 30 in the central portion of the protection portion 24 via a bridge 63. As shown in FIGS. 23 and 24, the fin pieces 36 are L-shaped and are integrally provided in the central portion of the protective portion 24 below the peripheral edge of the main volatilization hole 30. As shown in FIGS. 25, 26, and 27, the fin pieces 36 are rod-shaped and integrally provided in a bridging shape under the peripheral edge of the main volatilization hole 30 in the central portion of the protective portion 24. Next, as another embodiment, in FIGS. 28, 29 and 30, the protection portion 24 is provided with a fin piece 36 having a through hole 64 and a ring provided on the upper surface of the fin piece 36 via a plurality of connecting pieces 65. The hook 66 is formed integrally with the hook-shaped hook 66, a mounting plate 68 is integrally provided on the periphery of the volatilization hole 28 of the crown portion 21 via a rib 67, and a hook receiver 68b is provided along the periphery of the central hole 68a of the mounting plate 68. It is integrally provided, and the hook 66 of the protection portion 24 is engaged with the hook receiver 68b to attach the protection portion 24 to the volatilization hole 28. The through hole 64 of the fin piece 36 has a diameter equal to or smaller than the inner diameter of the heat radiation portion 26. However, a gap is formed between the upper surface of the fin piece 36 and the lower surface of the peripheral edge of the central hole 68a of the mounting plate 68. Further, the hook 66 of the protection part 24 may be integrally provided on the periphery of the central hole 68a of the mounting plate 68, or the hook 66 of the protection part 24 may be locked in the volatilization hole 28 of the crown part 21. , May be integrally provided.

As described above, various shapes and the like of the fin 36 can be considered, and it is possible to select a protruding shape, a ring shape, a plate shape, or the like. Since at least a part of the fin piece 36 is provided on the heating element heating portion, it is more effective in preventing foreign matter from entering and also can supply heat to the protection portion 24. In this case, it is important that the fin pieces 36 do not hinder the volatilization of the drug. From this point of view, the shape of the fin pieces is such that the shape just above the center of the liquid absorbent core is an evaporative passage for the evaporated drug. It is preferable because it can prevent the drug adhesion without hindering Considering the mounting structure of the fin piece 36, it is possible to mount only the fin piece 36 as a separate member from the upper body 3 and the protection portion 24, or the fin piece 36 is also used as the protection portion 24. You can also It is also possible to integrally form the fin piece 36 on the upper body 3 and / or the protection portion 24. If the fin piece 36 integrally molded with the protection part 24 is to be independent as a separate member, it should be installed on the crown part 21, the heating element 24, etc. by adhesion, welding, fixing, screwing, fitting, etc. It is also possible to improve workability especially by setting the mounting direction from above. It can also be sandwiched between the upper body 3 and the heating element 23. In this case, the heating element can be pressed as a member function, and the heating element 23 can be firmly fixed at a predetermined position. Furthermore, by not contacting the fin piece 36 and / or the protection portion 24 installed as a separate member with the upper body 3 directly, reducing the contact area, or installing the contact point at a position away from the heating element 23, The conduction heat can be reduced, and the heat conduction to the upper body 3 can be suppressed. When the fin 36 and / or the protection portion 24 are integrally molded with the upper body 3 via a bridge or the like, the conduction heat can be reduced by narrowing the bridge or keeping a distance, and the heat conduction to the crown portion can be reduced. Can be suppressed. When the fin piece 36 is installed so as to include the heating element 23, the protection portion 24 of the fin piece 36 can also be used. In addition, it can be provided closer to the heat generating body 23, so that the heat released from the heat generating body 23 can be efficiently absorbed, and a heat rising airflow is also easily generated. Also, the heat retaining effect of the heating element is improved, and even if the heating value of the heating element is suppressed, the same volatilization can be expected. As described above, the fin piece 36 is inside the volatilization hole 28 of the crown portion 21 or inside the main volatilization hole 30 in the central portion of the protection portion 24, near the center immediately above the heating element heating portion, and the amount of heat received by the fin piece 36. It is desirable that there be more than that of the protective part. The reason for this is that even if the fin pieces are present on the chemical vaporization passage, they are not cooled due to the high heat received by the fin pieces themselves, and the condensation of the volatilized chemicals is prevented. Furthermore, it also has the effect of enhancing the heat retaining effect by heat conduction also to the protective portion around the fin piece.

Next, as another embodiment, a main volatilization hole 30 having an inner diameter equal to or smaller than the inner diameter of the heat radiating portion 26 is provided in or around the volatilization hole 28 provided in the crown portion 21 of the apparatus body 1. A protective portion 24 is provided in which the distance between the volatilization hole 30 and the heating element 23 is 20 mm or less. Alternatively, the inner diameter of the volatilization hole 28 provided in the crown portion 21 of the device main body 1 is set to be equal to or smaller than the inner diameter of the heat dissipation portion 26, and the distance between the volatilization hole 28 and the heat generation portion 23 is set to 20 mm or less. As described above, the volatilization hole 28 is provided with the protective portion 24 having the main volatilization hole 30 whose inner diameter is equal to or smaller than the inner diameter of the heat dissipation portion 26, or the inner diameter of the volatilization hole 28 is equal to or smaller than the inner diameter of the heat dissipation portion 26. It is possible to prevent foreign matter from entering the main body 1 of the apparatus through the hole 26, and at the same time, to prevent an infant from accidentally putting a finger and getting a burn. By setting the inner diameter of the volatilization hole 28 or the inner diameter of the main volatilization hole 30 of the protection part 24 provided in the volatilization hole 28 to be equal to or less than the inner diameter of the heat dissipation part 26, the chemical liquid evaporated near the volatilization hole 28 or in the protection part 24. However, the inventors of the present invention found the following as a result of intensive studies. The drug evaporated from the heated body 45 (the liquid absorption core 41 or the impregnated body 46) heated by the heating element 23 is converged so as to be narrowed down on the heated body 45 and rises, and diffuses when it rises to some extent. To do. This is because the chemical evaporated from the heated body 45 rises while fluctuating toward the volatilization hole 28 or the main volatilization hole 30 along with the heat rising airflow generally generated from the inner circumference of the heat radiating portion 26. By applying a clean heat rising air flow toward the volatilization hole 28 or the main volatilization hole 30 through the periphery of 23 and above the heat generating body 23, the evaporated chemicals are wrapped in clean air and converge on the heated object 45. Then, it rises while being converged, and diffuses after passing through the volatilization hole 28 or the main volatilization hole 30. At this time, by setting the distance between the volatilization hole 28 or the main volatilization hole 30 and the heating element 23 to 20 mm or less, the above-mentioned clean heat rising airflow is naturally restricted by the internal space above the heating element 23. An air flow is directed to the volatilization holes 28 or the main volatilization holes 30, which promotes the convergence of the evaporated chemicals and further suppresses fluctuations inside the apparatus main body 1 to enable ideal evaporation. In addition, a rectifying plate for adjusting a clean heat rising airflow is provided inside the apparatus main body 1. Alternatively, a smoother air flow can be generated by forming the funnel around the volatilization hole 28 or the main volatilization hole 30.

[Effect of the device]

 By providing the protective portion 24 extending inward from the volatilization hole 28, the protective portion 24 can prevent foreign matter from entering the device main body 1 through the volatilization hole 28, and an infant accidentally puts his / her finger and is burned. Since the protection section 24 can prevent such a situation, the safety is improved. In addition, since the protector 24 has a plurality of fin pieces 36 with an interval equal to or smaller than the inner diameter of the heat dissipation portion 26, the same effect as described above can be expected. Further, the protective portion 24 has a main volatilization hole 30 having a diameter equal to or smaller than the inner diameter of the heat radiation portion 26, or the volatilization hole 28 has a diameter smaller than or equal to the inner diameter of the heat radiation portion 26, and the main volatilization hole 30 or the volatilization hole 28 and the heating element. When the distance from the heating element 23 is 20 mm or less, the same effect as described above can be expected, and the main evaporation hole 30 or the evaporation hole is 20 mm or less above the heating element 23 where the evaporated drug converges and rises. Since 28 is provided, the chemical agent does not adhere to the main volatilization hole 30 in the apparatus body 1 or the periphery of the volatilization hole 28.
