Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an insect control device installed in a kitchen, dining room, food storage room, etc.

Conventional structure and its problems Generally, in a kitchen room, etc., cockroaches live in a row and it is unsanitary. Therefore, measures to prevent intrusion include using an insect trap or using a gasket between the opening and closing member of the storage room. is taken.

Although the insect trap has some effect because it is placed in the path of cockroaches, it cannot prevent all the cockroaches from entering the storage chamber. Additionally, those that use seals may leave small gaps due to deterioration over time, and on the other hand, cockroaches can invade even if there is only one gap, so it cannot be said to be a complete pest control method.

By the way, cockroaches secrete a sticky substance on the backs of their legs, so when a voltage is applied to their legs, they are very sensitive and can easily feel the electric shock.

For this reason, an electric insect repellent device as shown in FIG. 6 has been developed. This insect repellent device consists of a plurality of electrode strips 2.2', 2" arranged almost parallel to each other on an insulating plate 1 with an insulating gap 3. The power supply 4 is configured to apply a low voltage, for example, a DC voltage of 6 to 20 V, to the comrades.

It has been confirmed that when the cockroach 6 is brought into contact with the electrode strips 2, 2' across the forks, the cockroach 6 receives a severe electric shock and turns back in the opposite direction to the direction of movement.

By the way, if the insulation gap 3 between the adjacent electrode strips 2, 2' is small, or if the voltage between the electrode strips 2, 2' is large, there is a problem that leakage occurs easily due to moisture, etc., and the battery constituting the power source 4 wears out quickly. be.

On the other hand, if the insulation gap is made large, small cockroaches cannot contact the electrode strips 2, 2' at the same time and cannot be given an electric shock, and if the applied voltage is made low, the electric shock cannot be given effectively.

Purpose of the Invention The present invention has been made in consideration of the above-mentioned conventional problems, and an object of the present invention is to provide an insect repellent device that does not cause leakage between electrode strips and can effectively apply electric shock to large cockroaches rather than small cockroaches. It is something to do.

Structure of the Invention In order to achieve the above object, the present invention arranges a plurality of electrode strips in parallel with each other with an insulating gap between them, applies a small voltage between adjacent electrode strips, and applies the same voltage between distant electrode strips. It is configured to apply a voltage higher than the voltage, so even if the insulation gap is small enough for a small cockroach to straddle it, there will be no leakage. It is an effective insect repellent.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numerals 6, 6' and 6'' are electrode bands, which are arranged substantially parallel to each other with an insulating gap 7, 7' between adjacent electrode bands.

Said insulation gap 7, 7' is relatively small, for example 1.
It is set to about 6 tones so that a small cockroach can straddle the two electrode strips 6, 6' and touch the two electrode strips 6', 6". The adjacent electrode strips 6 and 6' and 6' and 6" A required low voltage Ey is applied to each of the electrode strips 6 by their own power supplies 8 and 8', and the electrode strips 6 that are not adjacent to each other are
and e are the saturated voltages 2E of the two power supplies 8 and 8'.
v is applied.

The voltage Ey is set to a level that does not cause leakage in the insulating gaps 7, 7' and is sufficient to cause an electric shock, for example, 9V. Therefore, a high voltage of 18V is applied between the electrode bands 6 and 6''.

The electrode strips 6, 6', 6'' of the insect repellent device are arranged, for example, at the edge of the opening of the storage cabinet 9, as shown in FIG. 2. Reference numerals 10a, 101) in the figure represent cockroaches.

In the above configuration, the small cockroach IJ 10a comes into contact with the two electrodes 6, 6' across the insulation gap 7 and receives an electric shock. Also, as shown in the figure, the large cockroach 10b comes into contact with the electrode strips 6 and 6'' that are one space apart and receives a large electric shock.

Here, although the insulation gaps 7, 7' between each electrode band 6, 6', 6'' and the adjacent electrode band are small, the voltage applied between the adjacent electrode bands is small, so that no leakage occurs and large cockroaches are prevented. Since electric shock is applied to 10b by twice the voltage, effective insect control can be achieved.

FIG. 3 shows another embodiment of the present invention, in which four electrode strips 6, 6', 6", 6"' are arranged, and in this case, the distance between the distant electrode strips is The applied voltage increases as the voltage increases.

FIG. 4 shows another embodiment of the present invention, in which a plurality of power supplies aa and sb with different voltages are used. The power source 8a is connected to the adjacent electrode strips 6 and 6', and the power source 8b, which has twice the voltage, is connected to the distant electrode strips 6 and 6'', so that the electrode strips 6 and 6/, 6/ and Ey between 6”, 6 and 6
” means that a voltage of 2Ey is applied, and the same effect as described above can be obtained.

FIG. 5 shows another embodiment of the present invention, in which a commercial power source 11 is used, the voltage is stepped down and divided by a transformer 12, and the divided voltages are applied to adjacent electrode bands 6, 6'. and 6' and 6", and the total voltage is applied to electrode strips 6 and 6".
“ is applied, and the same effect can be obtained with this one.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, electric shock can be applied to even small cockroaches by providing electrode bands for electric shock and making the insulation gap between each electrode band and the adjacent electrode small. At the same time, there is no leakage in the insulation gap.
In addition, an effective electric shock voltage can be applied to large cockroaches.
The effect is great.
