Description

[Detailed description of the invention] The present invention relates to a material for heating evaporation.

Conventionally, there is a so-called insecticidal mat as a heating evaporation material, which is placed on an electric heating plate to evaporate the chemical, and the insecticidal mat merely holds the chemical. On the other hand, a positive temperature coefficient thermistor is used as a heating element to self-regulate the temperature, but since it consists of a combination of a heating element, an insulating plate, and a heat sink, the heat loss to the insecticidal pine that is the object to be heated is extremely large. For this purpose, the use of a minute DC power source such as a battery has been considered, but this has not yet been realized.

The present invention has been made for the purpose of eliminating the above-mentioned drawbacks and providing a material for heating and evaporation that can be heated at low cost and effectively even with a minute DC power supply. The present invention relates to a heating evaporation material characterized in that a conductive part made of a metal vapor-deposited film is formed on the entire surface.

In the present invention, since a conductive part is formed on the entire heated surface of the material for heating evaporation, this conductive part is used to prevent the heating element (positive It is possible to connect both electrode terminals of a characteristic thermistor to make it energized, while when it is not placed, the connection between both electrode terminals can be released to make it de-energized.
The heating evaporation material can be used as a kind of switch.

Further, the conductive portion is formed from a metal vapor deposited film and has excellent thermal conductivity, and since it is a vapor deposited film, it comes into close contact with the surface to be heated, and together with the fact that it is formed entirely on the surface to be heated, it can function as a heat sink.

Therefore, in the present invention, the safety in use of the evaporator can be improved by the function of the conductive part as a switch, and the thermal conductivity can be improved by the function as a heat sink. It becomes possible to use a DC power supply. Furthermore, since the conductive part can function as a heat sink, it can be used in a normal evaporator without any problem.

As a preferable evaporator for heating the heating evaporation material of the present invention, an electrode terminal on the heating element side provided in the evaporator;
An example of such a structure is that both the electrode terminal and the electrode terminal provided in the evaporator in a connected state are connected by a conductive part of the heating evaporation material.

In the present invention, the agents to be evaporated by heating include insecticides such as pyrethroid (common name: allethrin), geometric and/or optical isomers of allethrin, and pyrethroids with relatively high vapor pressure.
It is possible to use repellents such as N.N-diethyl-mettatoluamide, fungicides such as salicylic acid and parachloromethaxylenol, and flavoring agents such as lemon, rose, and green fragrances.

In the present invention, various commonly used materials can be used as the base material of the heating evaporation material, including natural fibers such as vegetable fibers, synthetic fibers such as propylene, inorganic fibers such as glass and asbestos, talc and diatomaceous fibers. Mineral powders such as earth, perlite, alumina, and silica can be used, and the fibers can be made into thin, nonwoven, or woven fabrics. Alternatively, by solidifying the powder with various binders, it can be made into shapes such as flat plates, sheets, and tablets. These shapes must match the evaporator.

In the present invention, the metal vapor deposited film constituting the conductive part is preferably formed from a metal material with as good thermal conductivity as possible, and for example, aluminum vapor deposition film, silver vapor deposition film, etc. are suitable.

An embodiment of the present invention will be described below based on the accompanying drawings.

FIG. 1 is a sectional view showing an example of the implementation of the present invention, in which 1 is a heating evaporation material, and a conductive part 3 made of a metal vapor deposited film is formed on the back surface of a base material 2, that is, the entire surface to be heated. There is.

FIG. 2 is a sectional view showing the state of heating and use of the product of the present invention shown in FIG. , the terminal portion 4-3 of the heating element 4-2 and the electrode terminal 4-4 of the evaporator 4 are connected by the conductive portion 3 of the transpiration material 1 to be in an energized state, and the transpiration material 1 is placed. When removed from portion 4-1, both terminals 4-3 and 4-4 are disconnected and become non-energized.

In the usage state shown in FIG. 2, the heating element 4
The heat from -2 is conducted to the heating evaporation material through the conductive part 3, that is, the metal vapor deposited film formed on the entire surface of the heated surface. Even when using a body, the purpose of heat conduction can be achieved with high thermal efficiency.

In the heating evaporation material according to the present invention, the conductive portion functions not only as a switch but also as a heat sink, and it is possible to simultaneously improve the safety of the evaporator and the thermal conductivity. Furthermore, since thermal conductivity can be improved, it becomes possible to use a minute DC power source such as a battery as a power source. Furthermore, since the conductive part also serves as a heat sink, it can be used in a normal evaporator without any problems.
