Description

  The present invention relates to a mosquito extermination device that captures and eliminates mosquitoes with an adhesive sheet, and more particularly to a mosquito extermination device using solar heat.

Conventionally, as this type of extermination device, there are those described in Patent Documents 1 and 2, for example.
The conventional product described in Patent Document 1 is provided with an attracting light equipped with a solar cell and a storage battery at the upper part of the leg. The attracting light is turned on by electricity generated by sunlight, and insects gathering in this light are captured with an adhesive sheet. It is a structure to do.
In addition, the conventional product described in Patent Document 2 is formed so that a blood-like liquid in a bag is warmed with sunlight, and when the mosquito sucks the liquid in the bag, the liquid is solidified in the body of the mosquito and can be controlled. Has been.

By the way, this kind of instrument using sunlight is used outdoors. Therefore, it is desirable that this type of instrument is formed so that the capture performance of the mosquito capture site, such as an adhesive sheet, does not deteriorate even if it gets wet with rain or dew.
However, since the conventional product described in Patent Document 1 is provided with the pressure-sensitive adhesive sheet in the vertical orientation around the attraction light, according to this, the pressure-sensitive adhesive sheet is wetted by rainfall or dew, Inevitably declined in a short period of time. As a result, the conventional product has a problem that the frequency of replacement of the pressure-sensitive adhesive sheet is high, and the pressure-sensitive adhesive sheet must be replaced with a new one without fully using the pressure-sensitive adhesive sheet.

Moreover, even if the conventional product described in Patent Document 1 uses sunlight, it has a structure in which an attracting light is turned on with sunlight, and insects are collected with light and captured with an adhesive sheet.
Therefore, this conventional product is effective for insects that gather in light such as spiders, but it is not effective for mosquitoes that prefer to fly in dark places. As a result, it should be used as a mosquito repellent. I could not.

In addition, the conventional product described in Patent Document 2 has a structure that uses sunlight to warm water once, and then heat-exchanges the heat of the water to heat a blood-like liquid.
Therefore, according to this, inefficiency in the use of solar energy, the structure for warming the liquid becomes complicated, and as a result, the number of parts increases and the apparatus becomes inevitable.

  In addition, this conventional product not only has a problem that dead mosquitoes are scattered around the instrument, but, similarly to the conventional product described in Patent Document 1, when it is installed outdoors, the chemical solution is not exposed to rain or dew. There was a problem that the bag was wet and as a result, the mosquito trapping performance was reduced.

Thus, mosquitoes prefer to fly in dark places, and land on a hot spot that is about the temperature of a human being to stab a human animal and suck the blood.
The present invention has been proposed in view of such characteristics of mosquitoes and problems of the prior art.

  Therefore, the technical problem to be solved by the present invention is to use sunlight, to capture and remove mosquitoes with an adhesive sheet, to warm the adhesive sheet using solar heat stored in a heat storage material, and By providing an adhesive sheet on the lower surface of the bottom plate of the shell, in other words, in a dark place that is shaded by the extermination part, it is possible to remove mosquitoes efficiently and reliably with a simple structure, and the adhesive sheet gets wet by rain or dew. The object is to provide a solar-powered mosquito repellent device that is formed so that it can be prevented.

The present invention employs the following technical means in order to solve the above problems.
That is, as shown in FIG. 1 and the like, the present invention is formed of an extermination part 3 provided with an adhesive sheet 2 for capturing the mosquito 1 on its outer surface and a leg 4 that supports the extermination part 3. It is a mosquito extinguisher, and the above-mentioned extinguishing unit 3 accommodates a heat storage material 12 that receives sunlight from the outside and stores solar heat, and the heat dissipation of this heat storage material 12 is conducted to the bottom plate 8 of the extinguishing unit 3, The pressure-sensitive adhesive sheet 2 is provided on the lower surface of the bottom plate 8 with the pressure-sensitive adhesive surface facing downward, and the pressure-sensitive adhesive sheet 2 is formed so as to be heated via the bottom plate 8 by heat radiation of the heat storage material 12. (Claim 1).

  In the case of the present invention, as the heat storage material 12, a commercially available product mainly composed of sodium sulfate hydrate, sodium acetate hydrate, paraffin or the like is used. Here, as a method of heating the adhesive sheet 2, specifically, the heat storage material 12 is directly placed on the bottom plate 8 of the extermination unit 3 to heat the bottom plate 8, or the heat storage material 12 is radiated by, for example, air. It implement | achieves by forming so that it may mediate to the baseplate 8.

  In the case of the present invention, the shape and structure of the extermination part 3 and the leg 4 are arbitrary. The extermination unit 3 is usually formed in a box shape or the like by combining a translucent member and a heat insulating material. In this case, it is preferable that the upper surface that receives sunlight is formed of a transparent plastic plate 7 made of, for example, polycarbonate so that the light transmittance is improved.

The plate 11 is lowered to block the communication state between the upper compartment 9 and the lower compartment 10, and when the temperature of the upper compartment 9 falls below the set value, the partition plate 11 is raised to raise the upper compartment 9 and the lower compartment 10 are preferably provided with an operating mechanism 13 (Claim 2).

  This is because the temperature of the upper compartment 9 can be increased to the maximum during the daytime when the amount of received light is large, and heat can be prevented from being dissipated from the bottom plate 8 of the extermination unit 3 during this time period. This is because the adhesive sheet 2 can be heated through the bottom plate 8 in the evening when the temperature of the upper compartment 9 decreases and the mosquito 1 actively flies around, and as a result, the capture rate of the mosquito 1 can be improved.

  In the case of the present invention, the operating mechanism 13 is preferably formed with a member such as a spring or wire made of a shape memory alloy that expands or deforms when reaching a set value. This is because this case can be realized without the need for a power supply or an electrically driven actuator, the structure can be simplified, and the cost can be reduced.

Further, in the present invention, it is preferable that the bottom plate 8 of the extermination part 3 is formed to include a convex heat receiving part 8a (claim 3).
This is because, according to this, the surface area of the bottom plate 8 can be increased, the heat conductivity is improved correspondingly, and the pressure-sensitive adhesive sheet 2 can be easily heated via the bottom plate 8. In the case of the present invention, the heat receiving portion 8a is specifically formed by press forming a large number of hemispherical or block-shaped convex portions, the bottom plate 8 itself is formed in a corrugated shape, or shown in FIG. 1B or the like. As described above, the bottom plate 8 is realized by forming the substantially curved half-wave rectified wave shape by alternately repeating the corrugated convex curved surface portion 8a1 and the planar portion 8a2.

  Since this invention is formed in this way, according to this, a mosquito can be exterminated with a simple structure using the solar heat stored with the heat storage material.

In the present invention, the pressure-sensitive adhesive sheet is formed so as to be warmed, and the pressure-sensitive adhesive sheet is provided on the lower surface of the bottom plate of the removal part, in other words, in a dark place which is shaded by the removal part.
Therefore, the present invention is suitable for the characteristics of mosquitoes, that is, the characteristics of mosquitoes that land in a warm place and prefer to fly in dark places. Can be disinfected.

Moreover, this invention has arrange | positioned the adhesive sheet below the extermination part in this way.
Accordingly, in the case of the present invention, the adhesive sheet can be prevented from getting wet by rain or dew when installed outdoors. Therefore, according to this, the adhesive performance of the adhesive sheet can be maintained for a long time, the replacement frequency of the adhesive sheet can be reduced, and the running cost can be suppressed.
