Description

[Detailed Description of the Invention] The present invention relates to an improvement in a fumigator, particularly a cordless type fumigator.

Cordless fumigators, such as cordless electric mosquito repellents, are often placed in the corner of a room or attached to a wall for long-term use.
In addition to the problem that the wall surface becomes dirty due to the adhesion of drug components over time, there are other problems such as the drug component not being able to sufficiently reach the center of the room.

The present invention has been made with the aim of eliminating the above-mentioned conventional problems. Namely, the present invention has a plug on the vertical back of the fumigator body, and an inclined plug extending obliquely downward from the upper end of the vertical back. In a cordless type fumigator in which a heating part is installed in the center of the upper surface, the vertical back surface of the main body has a forward inclined guide part at the upper part, and the heating part is arranged in the vicinity of the inclined guide part. , relates to a fumigator characterized in that an opening is formed in the inclined upper surface, and a blower fan is installed in the fumigator main body so as to substantially face the opening.

The present invention has the above-mentioned structure, and since the wind from the fan prevents the adhesion of drug components to the wall surface, it is possible to eliminate stains on the wall surface due to the adhesion of drug components and loss of adhesion of drug components, and the air flow Since the components are forcibly guided toward the center of the room, the drug components can be widely diffused to the center of the room.Furthermore, the above wind becomes an upward flow and carries the drug components to high places, so it can be used in places with high ceilings. It has the advantage of being able to fully achieve the purpose of extermination.

Furthermore, the sloping guide section at the top of the vertical back of the main body functions as a guide to guide the wind from the fan toward the guide center through the opening on the slanted top surface.
There is no need to provide any partition wall or the like as an air blow guide inside the main body, which simplifies the structure of the main body and, in turn, the fumigator, and reduces manufacturing costs. Furthermore, since there is no partition wall inside the main body, air is circulated throughout the main body by forced airflow from the fan, so the main body can be efficiently cooled by the circulating air, which contributes to preventing the temperature of the main body from rising and thus improving safety.

In this invention, the shape, size, and material of the main body are
It can be selected as appropriate depending on the usage situation (inside a ship, inside a warehouse, inside a hospital), etc.

In the present invention, the heat source for heating the drug may be anything that can generate heat in the range of 50° to 350°, such as semiconductors such as positive temperature coefficient thermistors, heating wires such as nichrome wires, and sheet heaters. Examples include, but are not limited to, heating elements using platinum catalysts, light bulbs, and fluorescent lamps. Light bulbs and fluorescent lights are advantageous in that they have an insect-attracting effect.

In this invention, the fan can be of any type that is commonly used, regardless of whether it is battery-powered or power-powered, as long as it is linked to a motor and uses its rotational force to rotate the fan and generate wind. Optional. The wind speed of the fan is usually in the range of 0.1 to 20 m/s, and if it deviates from this range, the object of the present invention may not be fully achieved, which is not preferable.

The fan can be mounted in any manner, and it does not matter whether it is mounted above or below inside the main body as long as it is substantially facing the opening of the sloping top surface.

As the chemicals used in the fumigator of the present invention, various fumigation chemicals used for this type of application can be used. Typical examples include insecticides, fungicides, repellents, rodent control agents, plant growth regulators, herbicides, fragrances, insect repellents, pharmaceuticals, etc., singly or in combination.

Depending on the type of drug, it can be used not only at home, but also in factories, ships, agricultural and horticultural greenhouses, warehouses, hospitals, etc., but is not limited to these.

The present invention will be described in detail below based on an illustrated example of the implementation of the present invention.

FIG. 1 is a longitudinal cross-sectional view showing an example of the implementation of the present invention, in which a pillar 5 is inserted into the opening 1b of the inclined upper surface 1a of the main body 1.
The vertical back surface 1c of the main body 1 has a heat dissipating plate 5 supported by heat sinks 5a and 5b, and a heating element 4 having lead-out terminals 4a and 4b at the bottom. and a fan 2 driven by a motor 2a is arranged inside the vertical back surface 1c,
An opening 6 is provided above the fan 2 and at the top of the inclined upper surface 1a.
This shows the case where . In this case, the fan 2 is installed perpendicularly from the floor A, but since it has the inclined guide part 3, the wind generated by the operation of the fan 2 is efficiently directed toward the center of the room by the inclined guide part 3. You will be guided. Therefore, the wall surface B is not contaminated at all by the evaporated components of the chemical (matte, paste) heated on the heat sink 5, and an extremely high stain prevention effect is obtained, as well as a diffusion effect of the chemical toward the center of the room. It can be obtained at the same time.

FIG. 2 is a longitudinal sectional view showing another example of the implementation of the present invention, in which the fan 2 is attached to the inner lower part of the inclined guide part 3 at the upper part of the vertical back surface 1c, and the plug 7 is attached around the axis by the shaft 7a. There is no substantial difference from that shown in Figure 1 except that it rotates 90 degrees downward in the direction of. In this case, since the fan 2 is tilted, the drug component is still guided toward the center of the room by this wind, and the same effect as described above is achieved.

Although the fan 2 shown in FIGS. 1 and 2 above is provided above the inside of the main body 1, it may be provided below inside the main body 1.
Further, as the power source for the fan 2, various types of batteries can be appropriately selected and used. Further, in the heat sink 5, the heating element 4 is a light bulb,
In the case of a fluorescent lamp or the like, it may be unnecessary or may be used in a mesh-like form. Light bulbs, fluorescent lamps, etc. have an insect-attracting effect, are cheaper than semiconductors such as positive temperature coefficient thermistors, and are advantageous when using low-temperature volatile chemicals.
