Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a pest extermination device that is equipped with a VC for furniture, kitchen equipment, etc. and eliminates pests such as cockroaches.

Conventional Structure and Problems Conventionally, this type of pest extermination device has a VCl as shown in Figure 1.
A battery 3 was connected between a pair of electrodes 1 and 2.

In this conventional pest extermination device, when the pest, especially the cockroach 4, attempts to climb over the pair of "MEs 1 and 2" and enter the furniture, when its limbs come into contact with the electrodes 1 and 2, the voltage of the battery 3 increases. As a result, the person receives an electric shock and retreats.This prevents the cockroach 4 from entering the furniture.

However, the battery 3 has a large internal resistance and a small current capacity. For this reason, even if the limbs of the cockroach 4 come in contact with the electrodes 1 and 2 of Naf, the electric shock given to the cockroach 4 is small, and the large cockroach 4 gets into the furniture even though it receives an electric shock. Something happened.

As a countermeasure to this problem, it is conceivable to lower the voltage in order to increase the current capacity of the battery 3, but this is a temporary measure.

OBJECTS OF THE INVENTION The present invention aims to eliminate the above-mentioned conventional drawbacks and provide a pest extermination device that can give a large electric shock to pests even when a low voltage is applied to a pair of electrodes.

Structure of the Invention In order to achieve the above object, the pest extermination device of the present invention includes a pair of electrodes to which a voltage is applied, which are laminated with an electrically insulating layer interposed therebetween, and at least a portion of the lower electrode is exposed. It is structured as follows.

Description of Examples Below, implementation of the present invention +! /1. lK will be explained with reference to FIG.

In FIG. 2, reference numeral 11 denotes furniture, and a wide first cage pole 12 is provided at the entrance of the furniture 11. 1
3 is a narrow electrical insulating layer formed on the first electrode 12;
14 is a second electrode formed on the electrically insulating layer. Note that the first electrode 12 is exposed on both sides of the second electrode 14. 16 is a battery connected between the first electrode 12 and the second electrode 14.

In the above configuration, pests, especially the thrush 16,
When trying to enter the inside, the first electrode 12 and the second electrode 14
If you come into contact with it, you will receive an electric shock.

In this case, since the first electrode 12 and the second electrode 14 are laminated, they constitute a capacitor, and the first electrode 12 and the second electrode 141C are charged with electric charges in advance. Therefore, when the pounding swing 16 contacts the first electrode 12 and the second electrode 14, the first electrode 12. The electric charge stored in the second electrode 14 is discharged, and a large electric shock can be given to the cockroach 16. For this reason, battery 1
6 does not need to be a high voltage one, but a loud tremor 1
It is possible to get rid of 6 as well.

Effects of the Invention As is clear from the above explanation, the pest extermination device of the present invention can give a large electric shock to pests even when using a low-voltage battery, and can reliably prevent large pests from invading furniture, etc. It can be prevented, and its industrial value is great.
