No. 2585, (2) Japanese Utility Model Publication No. 44-8361,

No. 6,086,098 is known.

In the above (1), the insecticidal liquid contained in the container is fumigated and volatilized, and as a heating element for heating the chemical liquid suction core, the chemical liquid suction core is surrounded by a space. A metal cylinder is fixed on a support made of a heat-insulating and insulating material having a circular lower end inner edge, a heater is provided outside the metal cylinder, and fine metal fibers having good heat conductivity are further provided inside. Is provided in a space between the liquid suction core.

The above-mentioned device (2) is a device for vaporizing and evaporating an insecticidal liquid, in which the periphery of a circular heat insulating and insulating support is brought into close contact with the inner side wall of the outer shell, and the upper surface is brought into close contact with the top. It is attached to the outer shell. A heat conductive metal cylinder is fitted and mounted at the center of the support, and a heater is mounted outside the metal cylinder.

Further, in the above (3), there is a heating element in which the heat radiating portion is independent and exposed, and the heat radiating portion is fixed to the heater portion by means of bonding, caulking, fitting or the like. The heating element is supported at a position deviated from the center of the heat radiating section.

Further, in the above (4), the heat radiating portion of the heating element is partially open in a U-shape, and the chemical liquid suction core is located in this opening.

[0007]

In each of the above-mentioned prior arts, in the case of (1), there is no ventilation upward from the lower part of the container and no ventilation around the outer periphery of the chemical suction core, and the heat rising airflow is reduced. There was a drawback that it did not occur smoothly, the drug remained inside the vessel, and efficient and stable expected volatilization could not be obtained.

[0008] Also, in the case of (2), a ventilation hole communicating from the lower part of the container is not provided, so that a heat-raising air current is not generated smoothly, the drug is trapped inside the container, and the intended No volatilization was obtained.

[0009] In the case of (3), since the heat-generating element is partially or unevenly provided at the heat-radiating portion support portion, the heat-generating member is supported by the heat-radiating portion support portion as a fulcrum to the heat-radiating portion tip. There is a disadvantage that the position of the heat radiating portion is easily deformed by the overload. This overload is likely to be caused by foreign matter entering from below or above, such as at the end of the liquid absorption wick when the bottle is attached, and the center of gravity of the heat radiating part is displaced from the supporting part of the heat radiating part. In some cases, the fulcrum of the heat radiating portion may be displaced or the heat radiating portion may be deformed due to the impact of the heat radiating portion. If the heat dissipating part is deformed or deviates from a predetermined position, the temperature distribution on the core surface will be biased when heating the chemical suction core, and further, the resin surface of the drug will occur on the core surface,
Due to a change in the engagement distance between the heat radiating portion and the suction core, stable desired volatilization of the drug cannot be obtained. Further, since the heat radiating portion is independent and exposed, a large amount of heat is radiated to the outer peripheral portion, the power consumption is correspondingly increased, and the heat distribution of the heat radiating portion is also poor because the heater portion is biased. ,
The desired drug volatilization was not obtained.

Further, in the case of (4), the temperature distribution on the surface of the wick during heating of the wick was poor, and the desired volatilization of the drug could not be obtained.

The present invention has been made in view of the above. In a heating and evaporating apparatus in which a heating element is provided at a position deviated from the center of a heat radiating portion, a heating device capable of solving the above-mentioned problems in the prior art. It is an object to provide a transpiration device.

[0013]

[Operation] When the chemical liquid suction core 14 of the bottle 3 is heated by the heat radiating cylinder 9a, an ascending air current is generated on the inner and outer peripheral sides of the heat radiating cylinder 9a, so that the vaporization of the chemical liquid does not stay in the container smoothly.
