Description

[Detailed explanation of the idea] The present invention relates to a heating transpiration device.

Traditionally, electric mosquito repellents use transpiration mats,
This transpiration pine is impregnated with a fixed amount of insecticidal liquid, but the insecticidal effect is usually about 8 to 10 hours, and the effective volatilization time of the insecticidal component is at most 6 to 8 hours.
It took about an hour, and it was not possible to obtain an effective volatilization effect continuously for a long period of time. In addition, as mentioned above, one transpiration mat can only be used effectively for about 6 to 8 hours, so two transpiration mats are required per day, and it takes time and effort to replace the transpiration mat, making it complicated to use. However, it had disadvantages from an economical point of view as well as the disadvantage that the heat source was limited.

The present invention was made with the purpose of providing a heating evaporation device that can eliminate the problems of the above-mentioned evaporation mats. It has a combination structure with a heating evaporation member installed below the container to receive the chemical solution from the container. a heat exchanger plate, a transpiration sheet placed and fixed on the upper surface of the heat exchanger plate, erected and fixed above the peripheral side of the evaporation sheet, the upper end of which fits into the chemical solution communication port at the bottom of the container during use; a cylindrical chemical liquid communication member that is fixed and supports the container; and a chemical liquid permeation member that is filled in the chemical liquid communication member and guides the chemical liquid from inside the container to the transpiration sheet when the communication member is connected to the container; The present invention relates to a heating evaporation device characterized by comprising:

According to the present invention, the heating evaporation device is installed and fixed above the transpiration sheet of the heating evaporation member by using the cylindrical chemical fluid communication member that is erected and fixed on the circumferential side of the sheet. It can be assembled, and after assembly, the heating transpiration device can be easily installed in the heating part of the electric mosquito repellent in the lower part of the transpiration sheet, and can be used in the same way as a normal transpiration sheet. can.

Furthermore, in such an assembled state, the chemical liquid is automatically and continuously supplied to the evaporation sheet of the heating evaporation member through the chemical liquid communication port at the bottom of the container and the communication member connected thereto, so that it does not last for a long time. In addition, since chemical liquid can be automatically and continuously supplied to the transpiration sheet in this way, it can be used not only for transpiration like a normal electric mosquito repellent, but also for high-temperature heating (e.g.
It is unique in that it can be used for fumigation at temperatures up to 350°C. In use, for example, when a heating evaporation member combined with a chemical solution container is placed on the heat sink of a commercially available electric mosquito repellent, and electricity is applied to the electric mosquito trap, the heat of the heat sink is transferred through the heating heat transfer plate. Since each part of the transpiration sheet is heated uniformly, there is less decomposition of the chemical due to heat.Furthermore, when the chemical impregnation rate of the transpiration sheet becomes low, the chemical is automatically replenished, allowing for effective evaporation of the chemical over a long period of time. . In the case of fumigation, if the temperature is set as above and the temperature is raised to about 350°C, the chemical can be fumigated instantly and effectively. When using fumigation, a large amount of chemical solution is instantly fumigated from the evaporation sheet, so if a wick is used to replenish the chemical solution to the transpiration sheet, the replenishment of the solution tends to be interrupted and the This makes fumigation difficult, but in this invention, the chemical solution is supplied from the top to the bottom through the chemical penetration member built into the cylindrical chemical communication member, so the chemical solution can be refilled smoothly and the chemical solution supply will no longer be interrupted, and there will be no hindrance to the use of fumigation. Furthermore, when using fumigation, if the transpiration sheet is directly heated at high temperatures, local heating will cause uneven fumigation, the chemical will thermally decompose, and the effective volatilization rate will decrease, and the transpiration sheet will not only be heated to localized high temperatures. However, in this invention, the transpiration sheet is placed on the heating heat exchanger plate, so this heating heat exchanger plate transfers the heat from the heating source to the evaporation sheet. On the other hand, it works to uniformly transmit information to each part, thereby eliminating the above-mentioned problems related to local heating. According to the present invention, it can be used not only for long-term transpiration (e.g. 12 to 24 hours) but also for short-term fumigation (e.g. 2 to 4 hours) by simply changing the heating source. It's convenient. The material for the above-mentioned transpiration sheet may be a sheet made of inorganic fibers such as asbestos or rock wool, pulp, or a sheet formed by molding inorganic powder with a suitable binder. Particularly preferred are those made from inorganic powder or the like.

In the present invention, the shape and size of the chemical liquid storage chamber are arbitrary, and the chamber may be provided so as to surround the entire periphery of the evaporation port of the electric mosquito repellent, or may be provided only in a part of the evaporation port of the electric mosquito repellent. The material may be synthetic resin, metal, etc. as long as it has heat and chemical resistance.

Further, the chemical liquid communication port provided in the chemical liquid storage chamber can be of any shape and size as long as the chemical liquid comes out, and it goes without saying that the chemical liquid communication port can be used as an injection port for additionally injecting the chemical liquid. The communication port may be provided with a lid or a stopper to prevent the drug solution from spilling during transportation, or may be simply sealed with a heat sheet made of aluminum or the like. Furthermore, to prevent spillage of the chemical solution, a container impregnated with a chemical solution may be stored in the storage chamber.

In the present invention, the heating plate in the heating evaporation member is provided for indirectly heating the evaporation sheet, and the shape and size may be selected as appropriate depending on the heat source used, and the material may also be selected. , materials suitable for this type of use, such as aluminum and copper, can be used as long as they have good thermal conductivity. Note that it is advantageous to form a suitable uneven shape on the heating heat exchanger plate because the heating area becomes larger.

Further, the chemical liquid communication member is for appropriately supporting the chemical liquid storage container at the upper end and appropriately guiding the chemical liquid from the container to the evaporation sheet via the internally filled chemical liquid permeable member, and is made of the above-mentioned heating heat exchanger plate. The heat exchanger plate may be provided as long as it has the same heat resistance as the heat exchanger plate, and may be provided integrally or separately from the heat exchanger plate, but it is preferable to provide the heat exchanger plate integrally with the heat exchanger plate if possible in order to obtain a firm standing and fixed state. The lower end opening of the connecting member must be connected to the upper surface of the transpiration sheet, and the shape may be curved or U-shaped, and the size may vary depending on the thickness and width of the transpiration sheet. It may be selected as appropriate.

In the present invention, the constituent material of the chemical liquid permeable member may be any material as long as it has the property of permeating the chemical liquid, such as synthetic fibers such as polyethylene, polypropylene, polyvinylidene chloride, or a nonwoven fabric made of such synthetic fibers and cotton. In addition, examples include textile fabrics, inorganic fibers such as glass wool, asbestos, and rock wool, and pulpy papers such as paper. This chemical liquid permeable member is used to control the amount of chemical liquid sent from the chemical storage chamber to the transpiration sheet, and is installed to hold the chemical liquid once and gradually impregnate the chemical liquid into the transpiration sheet. In addition, it may be installed in the chemical solution communication port of the chemical solution storage chamber.
In this case, it serves as a plug for the communication port. Note that the shape and method of providing the chemical solution permeable member are arbitrary as long as the above effects can be achieved.

In the present invention, various chemicals that have been conventionally used for purposes such as pest control, sterilization, and perfume can be used as the transpiration agent.

Various commonly used additives such as efficacy enhancers, volatilization rate improvers, deodorants, and fragrances can be optionally added to the above-mentioned transpiration agent.

As a heat source for indirectly heating the chemical for heating and transpiration impregnated in the transpiration sheet to evaporate the chemical solution, various types of heat sources that can provide a temperature at which the chemical can be evaporated or fumigated can be used. Specifically, the following heat sources can be advantageously used.

a. An electric heat source that heats by applying current. For example, a heating wire such as a nichrome wire, a sheet heater, a heater using a semiconductor, etc. can be exemplified.

b. Heat source using fire Examples include alcohol lamps, candles, gas burners, charcoal fires, kerosene, portable solid fuels, gelled alcohol, and gelled kerosene.

c. Methods that utilize the oxidation reaction of metal sulfides For example, a method in which a mixture of soda sulfide and at least one selected from iron carbide and carbon black is brought into contact with oxygen or air can be exemplified.
