Description

[Detailed description of the invention] Industrial applications This invention relates to an electric insect repellent device attached to a container.

BACKGROUND OF THE INVENTION In general, this type of furniture is easily invaded by cockroaches, so insect traps are used or insect-repellent gaskets are provided at the abutting portions of the openings and doors.

Since the insect traps are placed in the path of cockroaches, they are somewhat effective, but those that use packing may leave small gaps due to changes over time.On the other hand, cockroaches have gaps of about one word. It is difficult to say that this is an effective means of preventing insects, as insects can also invade.

By the way, cockroaches have sticky substances on the backs of their legs, so if a voltage is applied between their legs, they are very sensitive and susceptible to electric shock.

For this reason, an electric insect repellent device as shown in FIG. 5 has been developed. That is, two electrode strips 2, 2' are arranged on an insulating plate 1 with an insulation gap 3 interposed therebetween, and a low voltage, for example, 6 to 2 volts, is applied to the electrode strips 2, 2' by a power source 4. It is supposed to be done.

It has been confirmed that if the cockroach 5 moves and comes into contact with the electrode strips 2, 2', the cockroach receives a large electric shock and retreats.

For these reasons, the inventors of the present invention 1. As shown in FIG. 6, the electrode configuration 7 is attached to the opening edge of the cabinet 6,
We have considered ways to prevent cockroaches from entering the cabinet 6.

Problems to be Solved by the Invention By the way, the electrode assembly 7 has an insulating band 8 in the middle part and two electrode bands 9, 9' on both sides of the insulating band 8.
V-cut and bend 9o0 at 4 points.

Together, the ends 11 of the electrode arrangement 2 constitute a framework. Voltage is applied to the electrode strips 9, 9' by a power source 13 via lead wires 12, 12', and the purpose is to give an electric shock to the cockroaches 14 that try to pass through, thereby preventing them from entering. be.

However, some misalignment may occur during the butting operation of the end portion 1111'i of the electrode structure 7.
In this case, the outer electrode strip 9 (positive pole in FIG. 6) and the inner electrode strip 9/ (negative pole in FIG. 6) may come into contact and cause a short circuit, making it impossible to exhibit the insect repellent effect.

In addition, if a dimensional error occurs between the frame dimensions of the electrode assembly 7 and the frame dimensions of the opening edge of the cabinet 6, a gap may occur at the joint of the end portion 11, or the frame of the electrode assembly may be located outside the cabinet 6. In some cases, it protrudes from the surface, causing problems in terms of appearance and performance.

The present invention takes the above-mentioned problems into consideration and provides an electric insect repellent device with stable quality and good appearance. An elastically deformable insulating member is interposed between the parts.

As a result, even if the abutting portions of the electrode bands are misaligned, the insulating member prevents the positive and negative electrodes of the chamber structure from coming into contact with each other, thereby preventing short circuits.

Furthermore, even if a dimensional error occurs between the electrode band and the container, the elastic deformation properties of the insulating member allow it to be filled without any gaps, preventing cockroaches from entering through the gaps, and providing a good appearance.

EXAMPLE A first example of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, 1 is a cabinet for storing articles, 2 is an electrode structure disposed around the opening 1a of the cabinet 1, 3 is a door for opening and closing the opening of the cabinet 1, and 4 is a power source such as a dry battery.

The electrode structure 2 has a band shape with an insulating band 6 in the middle and two electrode bands 6, 6' on both sides. 6' may be made by integrally extruding a composite using a conductive resin containing carbon particles0.The electrode structure 2 is constructed by cutting the main parts into a V shape and bending them 9o0 to form a rectangular framework. are doing. Here, a soft insulating member 8 having elasticity made of foamed rubber or the like is fitted into the abutting portion A of the cut end of the electrode structure 2.
It is attached to the cabinet 1 with adhesive or the like.

A power source 4 is connected to the electrode bands 6, 6' through lead wires 9, 9'.
The voltage is applied.

Here, when the cockroach 1o tries to enter the inside of the cabinet 1 and comes into contact with the electrode band 6, 6', the voltage of the power supply 4 is applied to the cockroach 10, and the cockroach 11 receives a severe electric shock and retreats. Intrusion into the refrigerator can be prevented.

In the above structure, the electrode assembly 2 is sometimes attached by interposing the insulating member 8 between the abutting parts A, even if the abutting parts A are misaligned. The positive electrode (in the figure) and the inner electrode band 6' do not come into contact with each other and short circuit occurs, and the performance can be stably maintained. Further, the frame dimensions of the electrode assembly 2 and the frame dimensions of the opening edge of the cabinet 1 may have dimensional errors due to variations in processing dimensions and the like. In addition, when the electrode structure 2 is made of a resin material, expansion of the material due to temperature differences,
Due to shrinkage or material shrinkage due to changes over time, the gap C between the abutting portions A of the electrode structure 2 may change by opening or closing.

At this time, since the insulating member 8 interposed at the abutting portion is made of an elastic soft insulating material,
Since the insulating member 9 expands and contracts in response to the above-mentioned dimensional changes in the gap C, the insulating member 8 always fills the gap C, which prevents cockroaches from entering and provides an extremely good appearance.

In the figure, the thickness of the insulating member 8 is set higher than the surface of the electrode structure 20 by a certain amount. This is because when the door 3 is closed, the dimensions become a cushion and come into close contact with the back side of the door 3 to provide sealing properties.As a result, a gap is created between the insulating member 8 and the door 3. hand,
Cockroaches 10 can be prevented from entering through this part.

3 and 4 show another embodiment of the present invention, in which the cabinet 1 has an L-shaped opening 1a, and the left and right electrode structures 2 are located at the corners of the L-shaped opening 1a. They are attached at right angles to each other with an insulating member 8 having a cushioning property interposed therebetween. In addition, the insulating member 8 is
The dimensions are set high.

In this case as well, the abutting portion A of the electrode structure 2 has the same effect as described above.

Effects of the Invention As is clear from the description of the above embodiments, the present invention uses an insulating member between the electrode strips when abutting insect-proof electrode strips around the opening of a cabinet, etc. Insulation is reliable, and the insulating member is elastically deformable, so even if there is a dimensional error between the electrode band and the container, there will be no gap between the electrodes, further improving insect repellency. Dogs are valuable in that they are able to perform well, as well as have a good appearance.
