Description

[Detailed description of the invention] Industrial application effect This invention relates to a vaporization and transpiration type pest extermination device that uses a chemical that generates insecticidal gas by evaporation or sublimation. It is designed to vaporize and transpire to increase extermination efficiency.

PRIOR TECHNOLOGY Vaporization and transpiration type pest extermination devices, which are commonly used to exterminate pests in living rooms and warehouses, store liquid chemicals in a container and blow hot air onto them or heat the container to expel the chemicals. Usually, devices that evaporate or sublimate the drug by heating a solid material mixed with a solid drug on a heating plate, but these devices require a considerable amount of heat source, so they are small in size. To exterminate a limited number of insecticides in relatively large quantities, fumigation type or aerosol type directly filled with insecticidal gas is used, which may be dangerous in handling.

Problems to be solved by the invention To solve this problem, instead of the above-mentioned capacity, a material with a high adsorption rate, such as vermiyukilite, is impregnated with a liquid drug, and hot air is blown onto it to evaporate the liquid drug. In this case, the insecticidal gas can be generated and blown out at the same time, and the surface of vermiyukilite can be used to greatly increase the evaporation area, which means the amount of gas generated can be increased. The hot air to be applied needs to have a considerable amount of air and be sufficiently and evenly heated in advance. However, it is structurally uneconomical to provide a device that generates hot air, so in reality, the drug carrier is heated with an appropriate heat source to vaporize it, and the generated gas is sucked together with air using a blower. The only option is to create a structure that blows the air into the air, which means that air heated by a heat source is surrounded by a large amount of suction air, so the overall temperature of the hot air does not rise that much, and the heated air does not reach the drug carrier. In addition to the contacting parts, there are parts that are blown by the suctioned air at room temperature and are cooled by bending, so that forced evaporation due to heating is extremely reduced.

The purpose of this invention is to provide a structure that combines the above-mentioned small-capacity heat source and an air blower, and also to be able to obtain a required evaporation temperature and a satisfactory air volume.

Means for Solving the Problems In this invention, an embodiment is explained with reference to the drawings. 1 is a box-shaped main body made with a square or circular cross section, and circular air outlets 2, 2 are provided on the top surface of the box-shaped main body. A blower 3 is provided together with a motor 4 within the outlet, and air intake ports 6 are provided in horizontal rows on both sides of the air outlet, connected to the lower edges of the outwardly projecting portions 5. Inside the main body 1, a drug carrier mounting plate 7 made of a grid or wire mesh is installed horizontally above the air intake ports 6..., 6..., and a pipe is placed above the air intake ports 6..., 6... A heat source 8 consisting of a heater is provided, and a reflector plate 9 made of a stainless steel plate is placed directly below the same, and between the drug carrier placement plate 7 and the heat source 8, several window holes are provided in the metal plate for air flow. A regulating plate 10 is stretched horizontally. FIG. 4 shows this air volume regulating plate 10, and the window holes 11 are circular holes that open to intersect with the projected outline of the air outlet 2 on the surface of the air volume regulating plate 10, as is clear from FIG. It is arranged as.

Function This device has the above-mentioned structure, and the opening/closing part 12 provided at one end of the main body 1 is opened and the drug carrier a, which is made by impregnating vermiyukilite with a large amount of drug solution, is placed on the drug carrier placement plate 7. After placing it, the opening/closing part 12 is closed and the heat source 8 and the blower 3 are operated. Then, the air intakes 6..., 6 on both sides are opened by the blower 3...
The external air sucked in from ... is heated through the heat source 8 and the reflection plate 9, rises above the heat source as hot air of 90°C to 60°C, and is ejected to the outside from the outlet 2... along with the gas generated from the drug. However, since the window holes 11 provided in the air volume regulating plate 10 enter directly below the air outlet 2, this hot air is collected directly below the air outlet 2 through the window holes 11... and each window hole 11... serves as a nozzle to increase the wind speed. In this way, drug carrier a...
The portion directly above each window hole 11 is heated, and the side and top surfaces, especially the portion directly below the ejection port 2, are heated by the rising hot air, and the blowout port 2...
The air volume regulating plate 10 blocks the area other than the area immediately below and a certain area surrounding this area, and no upward air current is generated. Therefore, the hot air does not heat unnecessary spaces and concentrates only the drug carrier a... Heat it up and open the air outlet 2...
Since the heat source 8 can efficiently promote vaporization and transpiration of the drug, the heat source 8 may have a relatively small capacity.

Effects of the invention This invention increases the capacity of the heat source 8 with the reflective plate 9, and furthermore, by interposing the air volume regulating plate 10 having window holes 11 at predetermined positions, the drug carrier a can be heated efficiently. At the same time, during the evaporation of the drug, the coexistence period of the liquid and gas is appropriately preserved, which means that the moist saturated vapor can be maintained for a predetermined period of time, which is advantageous for replenishing the drug carrier a, etc. There are advantages.
