Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field The present invention provides an electric shock to small animals such as cockroaches (hereinafter also referred to as cockroaches) that engage in walking activities that are harmful to hygiene. This invention relates to an electric insect repellent device that prevents insects from entering storage rooms such as tables and other storage cabinets.

Configuration of conventional examples and their problems In general, the 8th method is used to repel or evade cockroaches by giving an electric shock to cockroaches.
What is shown in the figure has already been proposed. This consists of a pair of electrode bodies 1a and 1b that are arranged opposite to each other with a small insulation interval W, and a
The power source 2 is a dry battery or the like that applies a low voltage of 40 volts.

If the structure described above is installed in a place where you do not want the cockroaches 3 to enter, for example, at the entrance of the article storage chamber A, the cockroaches 3 that have walked from the outside B will cross both electrode bodies 1a on the way to the storage chamber A. ,1b
At this time, the current from the electrode bodies 1a and 1b flows inside the cockroach 3's body, so this electric shock causes the cockroach 3 to move outward B.
This prevents the cockroaches 3 from entering the storage chamber A.

By the way, the electrode bodies 1a and 1b are generally made of iron,
It is made of metal materials such as aluminum and copper, but in this case, electrolytic corrosion occurs in an extremely short period of time, and good quality cannot be maintained over a long period of time. It was unsuitable.

OBJECTS OF THE INVENTION The main object of the present invention is to provide an electric insect repellent device that can maintain good quality over a long period of time.

Structure of the Invention In order to achieve the above object, the electric insect repellent device of the present invention includes a pair of elongated electrode bodies facing each other with a small insulation gap, and a power source that applies voltage to the electrode bodies. The electrode body is formed by embedding a conductive core wire made of a metal material along the longitudinal direction within an electrode band made of conductive plastic, and according to this structure, it can be used for a long period of time. It has the advantage of being able to maintain good quality.

DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 1 to 7.

In FIG. 1, reference numeral 1 denotes a long electrode body, and this electrode body 1 includes an electrode band 1a made of conductive plastic, for example, a plastic made of a mixture of vinyl chloride and carbon, and a longitudinal part of the electrode band 1a. It is formed by extrusion molding or the like from a conductive core wire 2 buried along the direction. As the material of the core wire 2, a metal material such as copper, aluminum, or iron is used.

At least one pair of electrode bodies 1 are arranged facing each other with a small insulation interval W, and the electrode bodies 1,
An electric insect repellent device is constructed by connecting a power source 3 such as a dry battery to the insect repellent.

In the above embodiment, the electrode bodies 1 and 1 were formed separately and placed facing each other, but as shown in FIG. It may be integrally formed.

The electric shock type insect repellent device consisting of the above is similar to the conventional example,
It is set in a place where you do not want cockroaches 4 to enter, for example, at the entrance/exit of an article storage chamber 5, and when a cockroach 4 walking from the outside 6 comes into contact with both electrode bodies 1, 1, an electric shock is applied to the cockroach 4. It gives a shot to make the cockroach 4 go back.

By the way, since the electrode band 1a of the electrode body 1 is made of conductive plastic, due to its characteristics, the progress of deterioration due to electrolytic corrosion is much slower than that of metal materials, and therefore it lasts much longer than metal materials. Good quality can be maintained. However, deterioration over time during extremely long-term use, such as cracks occurring in the electrode band 1a due to the plasticizer leaking out, is unavoidable.
In such a case, if the electrode band 1 is formed, there is a risk that the current will be cut off midway, but in the present invention, the core wire 2 is buried in the electrode band 1a, so there is no possibility that the electrode band 1a will be cracked. Even if this happens, there is no risk of current interruption, and good quality can be maintained for many years. In addition, since the core wire 2 is buried along the longitudinal direction of the electrode band 1a, the electrode resistance of the electrode body 1 can be reduced, and therefore, compared to the case where the core wire 2 is not buried, the electric shock against cockroaches 4 is larger. It is something that can be given.

The electrode body may be placed around the opening of the storage cabinet 7 as shown in FIG. This setting configuration, that is, the configuration at the corner part A, is as shown in FIG. 4, in which both ends of the electrode body 1 are cut at 45 degrees, and these cut surfaces are brought into contact with each other to establish conduction. As shown in the figure, make a V-cut B leaving only one electrode body 1, bend both electrode bodies 1, 1 inward from this V-cut part B, and make a V-cut part B.
Various configurations are conceivable in which the cut surfaces 1', 1' of the electrode body 1 are brought into contact with each other in order to establish conduction, but considerable precision is required to ensure that the cut surfaces 1' and 1' of the first electrode body are brought into contact with each other without causing any disconnection. This is an extremely difficult technique. However, when cutting the electrode body 1, as shown in FIG. 7, if the core wires 2, 2 are made to protrude from the cut surfaces 1', 1', conduction can be achieved without requiring precision. That is, the core wires 2, 2' can be entangled with each other and connected, or the core wires 2, 2' can be connected by soldering. Further, when the electrode bodies 1, 1 are bent as shown in FIG.
A crack D may appear in the conductor, causing non-conductivity.
Even in this case, since the core wire 2 is buried, the electrode body 1 itself does not cause non-conductivity.

Note that the core wire 2 does not necessarily have to be buried in both electrode bands 1a, 1a, but as described above, it may be buried in at least one electrode band 1a on the side where cracks D are likely to occur due to bending of the electrode body 1. It's fine if you have one.

Effects of the Invention As described above, since the present invention uses conductive plastic as the electrode band, it can maintain good quality for a much longer period of time than metal materials. Furthermore, since the core wire is embedded within the electrode band, non-conductivity of the electrode body is less likely to occur, and good quality can be maintained in this aspect as well. Furthermore, since the core wire is buried along the longitudinal direction within the electrode band, the electric shock to the cockroaches can be increased.
