Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to small animals such as cockroaches (referred to as microscopic cockroaches) that engage in walking activities that are harmful to hygiene.
Storage rooms such as other storage cabinets, living rooms,
This invention relates to an electric insect repellent device that prevents insects from entering living spaces such as bathrooms.

Conventional Structures and Problems Generally, the structure shown in FIG. 1 has already been proposed as a device for repelling or repelling cockroaches by giving an electric shock to them. This is a pair of electrodes 1a, 1b'
i. They are arranged facing each other on an insulating base material 2 with a small insulation interval wl, and a voltage such as a dry cell battery 3 is applied between the electrodes 1a and Ib, and the cockroach 4 is positioned astride both electrodes 1a and 1b. When this occurs, the current from both electrodes 1a and 1b flows into the body of the cockroach 40, thereby causing the cockroach 4 to receive an electric shock. If it is set on the front wall surface of 6mm, it is possible to make it difficult for cockroaches 4 to enter into the housing chamber 5b. The cockroach 4 that has been walking in the direction of the arrow A from the outer wall surface 6C of the double cabinet 6 is
On the way to the accommodation chamber 6b, it comes into contact with the electrodes 1a-, 1b, receives an electric shock, and falls outside the accommodation chamber 6b as shown by arrow B.

However, simply connect both electrodes 1a and 1b with a small insulation interval wl.
If the cockroach 4 is set around the article entrance/exit 6, the cockroach 4 will pass through both the electrodes 1a and 1b'i without being subjected to the electric shock a, and will growl inside the storage chamber 6b as shown by arrow C in FIG. This may lead to. Specifically, the inventors conducted an initial experiment with the insulation interval W set at 6rrrln, and in this case, the cockroaches 4 were found to have invaded the housing chamber 5b. When the body length of the cockroach 4 that had invaded (approximately equal to the length between the front and back legs) was examined, it was found to be less than 6 cm, which indicates that the cockroach 4 with a body length that is less than the insulation interval W has invaded the storage chamber 5b. . In the case of a cockroach 4 whose body length is shorter than the insulation interval W, as shown in FIG. It has been found that by touching only one of the electrodes 1a', 1b, the user passes through the electrodes 1a, 1bi without receiving an electric shock, and ends up in the accommodation chamber 5b.

Purpose of the Invention 9 The present invention has been developed focusing on the above point, and it is possible to give an electric shock to a larger number of cockroaches, thereby causing less of the above-mentioned inconveniences, and reducing the possibility of short circuits. The purpose of the present invention is to provide an electric shock type insect repellent device that can reduce the risk of damage.

Structure of the Invention In order to achieve the above object, the electric insect repellent device of the present invention has the following features:
This is a configuration in which the insulation gap between the two electrodes is approximately f2rran, and with this, the number of cockroaches that can be shocked by electric shock can be increased, the invasion of cockroaches can be further reduced, and the possibility of short circuits can also be reduced. There are advantages such as being able to

DESCRIPTION OF EMBODIMENTS The present invention will be described in detail below, but since the configuration except for the insulation interval W dimension is the same as the above-mentioned configuration, the insulation interval W will be mainly explained.

As described in the section on the structure of the conventional example and its problems, cockroaches 4 whose body length is shorter than the insulation interval W dimension will reach the containment chamber 5b without receiving an electric shock. If the size is made as small as possible, more cockroaches 4 will be hit with electric shock. However, if the insulation interval W is made too small, the electrodes 1a and 1b are likely to be inadvertently short-circuited, resulting in inconveniences such as wasted power consumption. In other words, if water droplets (not shown) are applied to the electrodes 1a, 1b or the insulation interval W, if the insulation interval W is too small, even a very small drop of water will easily contact the electrodes 1a, 1b. This is what you will do. Furthermore, even if the electrodes 1a, 1b and the insulation interval W portion are integrally molded from a resin material, if the insulation interval W is too small, even a slight variation in molding will cause the electrodes 1a and 1b to
This causes a and 1b to come into contact with each other. As a result of conducting various experiments to find out how much the insulation interval W should be, it was found that about 2 m is appropriate. In other words, the body length of Cockroach 4 is the smallest German cockroach,
For adults, it is about 11mm, and for larvae, it is about 2rrrln, so if the insulation interval W is set to about 2mm, then all cockroaches will have a body length of 2rra.
If the cockroach 4 is about n or larger, an electric shock will be given. Of course, the insulation interval W dimension f2r
Even if tunL9 is a small value, for example, about 1wn or less, an electric shock will be given to almost all the cockroaches 4 as described above, but since the body length of the cockroaches 4 is at least about 2 mm, the insulation interval W dimension should be set to 1++ m. There is no point in making the insulation interval W smaller than that, and rather, the smaller the insulation interval W is, the more the insulation interval W is reduced.

This only makes it easier for 1b to be inadvertently short-circuited.

In the present invention, since the insulation interval W is about 2111 m, the possibility that the electrodes 1a and 1b will be inadvertently short-circuited is lower than that of one case or less.
The effect of giving an electric shock to a person is almost the same as that of one below. In addition, insulation interval W dimension'
The reason for setting it to about 12 mm is to take into consideration the tolerance of ±o and 6 mm when manufacturing both electrodes 16g1b'i. The invention is therefore not limited to 2 m, but is meant to include insulation W dimensions between 1.6 m and 2.6 m.

Effects of the Invention As mentioned above, according to the present invention, it is possible to apply an electric shock to all kinds of cockroaches, from small cockroaches to large cockroaches, so that the intrusion of cockroaches into the containment chamber can be further reduced. Moreover, the possibility of a short circuit occurring between both electrodes can be reduced.
