Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric insect repellent device that applies an electric shock to insect pests such as cockroaches to repel or repel them from entering kitchen furniture or the like.

2. Description of the Related Art Conventional Structures and Problems There is known an electric insect repellent device having a structure shown in FIG. 1, which repels or prevents pests such as cockroaches from entering kitchen furniture.

In this case, a pair of sheet-shaped electrodes 1a and 1b are arranged facing each other on the same plane with a distance W2, which is much narrower than the interlimb width W1 of the cockroach 2, for example, between 1 and 2.

Then, a DC power source 3 such as a dry cell battery is applied between the pair of sheet-like electrodes 1a and 1b, and when the cockroach 2 touches its front and rear legs between the two electrodes, the sticky substance on the soles of the legs becomes conductive. Because it is charged with electricity, you will receive an electric shock.

Therefore, if such an electric insect repellent device is placed at the entrance of kitchen furniture or in a sunken area, it will be able to repel cockroaches and prevent cockroaches from approaching the furniture due to their own repellent ability. .

However, the problem with such a device is that the pair of sheet-like electrodes 1a and 1b must be kept very close to each other with a distance W2 of about 1 to 2 mm so that they can be repelled regardless of the size of cockroaches. The problem is that it is difficult to arrange them without misalignment.

If the distance W2 is widened, it is easier to install the electrodes, but if the width between the front and rear limbs is narrow, such as in small cockroaches or larvae, the front and rear limbs may not touch each other because they tend to intertwine between the two electrodes. and does not function adequately as an insect repellent device. On the other hand, narrowing the spacing improves the insect repellent function, but short circuits due to partial contact between a pair of electrodes and sparks when the electrodes come close to each other are likely to occur, and the installation of the electrodes itself requires skill and difficulty.

OBJECTS OF THE INVENTION The present invention aims to solve these conventional problems and provide an electric insect repellent device that is easy to install and exhibits excellent electric insect repellent effects. In order to achieve the above object, the present invention has a pair of upper and lower sheet-like electrodes, an insulating sheet is arranged on the upper surface of the lower electrode or its extended surface, and an upper electrode is arranged on the insulating sheet. , is characterized in that a voltage is applied between both electrodes.

In such an electric insect repellent device, the distance between the upper and lower electrodes can be well regulated by insulation sorting, and it can be easily installed on kitchen furniture, etc., and exhibits an excellent electric insect repellent effect.

Embodiments of the present invention will be described below with reference to the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 2 shows an electric insect repellent device according to a first embodiment of the present invention, in which 4a is made of aluminum foil fixed to the entrance or recessed part of kitchen furniture by using it as a pedestal. It is a sheet-like lower electrode having a desired thickness tl,
For example, the second sheet-like electrode 4b is disposed above the insulating sheet 6 with a thickness of 1 mm by adhesive or the like, and the whole is integrated. As is clear from the figure, the upper sheet-like electrode 4b is formed to have a width of 1< than the lower electrode 4a, and the end faces of both electrodes 4a and 4b are stacked so that there is a step difference.

Further, between the pair of upper and lower electrodes 4a and 4b, there is a voltage sufficient to apply an electric shock to the cockroach 2, for example, 6V, preferably 2QV.
A DC voltage 3 of 3 is applied from a dry battery. Therefore, when the cockroach 2 crosses this insect control device from the right side of the figure to the left side or from the hanging wall surface, when the forelimbs and middle legs or hind legs touch 4b and 4a, respectively, while trying to move from the bottom to the top, the soles of the legs as described above. The conductive sticky substance exhibits electricity, and the cockroach 2 is shocked by the electric shock, causing it to jump and go into a state of shock. By experiencing this electric shock several times, cockroaches acquire the ability to avoid this insect repellent device, and will not approach it for a while afterward and will not attempt to invade the kitchen furniture.

FIG. 3 shows a second embodiment of the present invention, in which an upper electrode 4b is arranged in a stacked manner above a sheet-like lower electrode 4a with an insulating sheet 6 interposed therebetween, and its insect repellent function is the second embodiment. Obtained similarly to what is shown in the figure.

FIG. 4 shows a third embodiment of the present invention, in which an insulating sheet 6 is arranged on an extended surface of the upper surface of a sheet-like lower electrode 4a, and a sheet-like upper electrode 4b is arranged thereon. be. In this case as well, the same insect repellent function as described above can be obtained.

In addition, for the sheet-like electrodes 4a and 4b under "1", in addition to a highly conductive metal sheet such as aluminum foil, a carbon-containing conductive resin sheet can also be used.
, 4 B to ensure electrical insulation and spacing between the insulation sheets 5 and 5.
This can be sufficiently achieved by changing the thickness t. In addition, an insect repellent device with a so-called laminate structure, as shown in Figures 2 and 3, can be easily installed in the entrance area of kitchen furniture or in a sunken area. If it is installed, it can be installed on metal objects without using nails or the like.

Note that the dry cell or the like that constitutes the DC power source 3 is only energized when the cockroach comes into negative contact with the lower electrode, and normally only voltage application is required, so it hardly wears out.

In addition, the power consumption when applying an electric shock to a cockroach is about 3 μA, which is enough for the commonly seen black cockroach.

It can be used for 1 to 2 years without needing to be replaced because it requires only about 6 μA even for German cockroaches.

FIG. 5 shows a pair of upper and lower sheet-like electrodes 4 arranged to frame the entrance of kitchen furniture as a specific example of the implementation of the present invention.
This shows an electric insect repellent device consisting of parts a and 4b, which can effectively prevent cockroaches from entering even if there is no door.

Effects of the Invention As described above, the electric insect repellent device of the present invention can satisfactorily regulate the distance between the pair of sheet electrodes, is easy to install on kitchen furniture, and has excellent insect repellent effects.
