Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an electric insect repellent device attached to storage furniture, sink cabinets, etc. installed in kitchens, 2 dining rooms, 9 food storage rooms, etc.

Conventional technology Generally speaking, cockroaches can easily invade this kind of furniture, so insect traps are used or insect-proof seals are installed at the abutting areas of the opening and the door.

Since the insect traps are placed in the path of the cockroaches, they are somewhat effective but cannot be said to be completely effective, and those that use packing may cause slight gaps due to deterioration over time. It is difficult to say that this is an effective insect repellent method, as cockroaches can enter through gaps as small as one throat.

By the way, cockroaches secrete a sticky substance on the backs of their legs, so when a voltage is applied between their legs, they are very sensitive to electric stimulation.

For this reason, an electric insect repellent device as shown in FIG. 6 has been developed. That is, two electrode strips 2, 2' are arranged on an insulating plate 1 with an insulating gap 3 interposed therebetween, and a low voltage, for example, 6 to 20 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 6 moves here and comes into contact with the electrode strips 2, 2', the cockroach receives a large electric shock and retreats.

For this reason, the present inventors have devised a means to prevent cockroaches from entering the cabinet θ by attaching an electrode structure and a body 7 to the opening edge of the cabinet 6, as shown in FIG. Ta.

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. A voltage is applied between σ by a power supply 1o. Here, the electrode assembly 7 is mounted on the cabinet 6 by driving the stable 11 etc., and at this time, the back surfaces of the electrode strips 9, 9' are brought into contact with the terminal plates 12, 12', and the leads are connected via the lead wires 13, 13'. It is connected to power supply 4. This method allows wire connections to be easily made without any special processing on the electrode structure 7. However, as shown in FIG. 8, if the electrode structure 7 warps, the electrode band 9゜9′
There have been cases where the contact between the terminal board 12 and the terminal plate 12 and 12' becomes separated, resulting in poor contact. Here, when attaching the electrode assembly 7 with the stable 11, the warp can be corrected by attaching the stable 11 to both ends of the electrode assembly 7 instead of attaching the stable 11 to the center of the electrode assembly 7. However, in this case, the stable 11 is generally made of metal, and the cabinet 6 is made of wood. , current may leak from the stable 11 that is set at both ends through the moisture contained in the cabinet 6.
Undesirable.

The present invention takes the above-mentioned problems into consideration and provides an electric shock type insect repellent device that ensures reliable contact between the electrode structure and the terminal side and has good quality stability.

Means for Solving the Problems In order to achieve the above object, the present invention forms a groove in the middle of the back surface of an electrode assembly, and exposes electrode bands on both sides of the groove.

As a result, even if the electrode structure is slightly warped, since the electrode bands on both sides protrude toward the terminal plate, the contact between the electrode bands and the terminal plate is good.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 4.

In the figure, 1 is a cabinet that stores articles, 2 is an electrode structure disposed around the opening edge of the cabinet 1, 3 is a door that opens and closes the opening of the cabinet 1, and 4 is a power source. The electrode structure 2 has a cross section with an insulating band 5 in the middle and two electrode bands 6° 61 on both sides, and is formed into a band-like shape. For example, the insulating band 5 is made of insulating resin. It is conceivable to use a conductive resin containing carbon as the electrode bands 6, 6', and to make them by composite extrusion molding.

The back side of the electrode structure 2 has electrode bands 6 on both sides of the insulating band 5,
It has a structure in which a concave groove 6a is formed in the middle of the door 6' protruding from the bottom surface, and a rubber-like packing body 7 is provided on the front side to absorb the impact when the door 3 is opened and closed. ing.

8 is a terminal unit, metal terminal plates 9, 9',
The connection is made using lead wires 10 and 10, and this connection portion 11 is molded with insulating resin.

The terminal unit 8 is installed through a hole 12 made in the opening edge of the cabinet 1, and the lead wire 10.degree. 10 is connected to a power source 4 such as a dry battery.

In addition, the electrode structure 2 is made by driving a stable 13 etc.
When installed in the cabinet 1, the back surfaces of the electrode strips 6, 6' of the electrode assembly 2 and the terminal plates 9, 9' are brought into pressure contact, and electrical continuity is established between the electrode strips 6, 6'. A voltage from a power source 4 is applied to the .

Here, when the cockroach 14 tries to enter the inside of the cabinet 1 and comes into contact with the surface of the electrode band 6゜6' of the electrode assembly 2, the voltage from the power supply 4 is applied to the body of the cockroach 14, and the cockroach 14 It is designed to give large electric shocks to make them disperse and prevent them from entering the refrigerator.

In the above configuration, the electrode assembly 2 often warps depending on the temperature and deterioration over time.

FIG. 4 shows a state in which the electrode structure 2 is curved convexly on the back surface from FIG. Since the electrode band 6,
Since the back surface of the terminal plate 6' comes into contact with the terminal plate 9.9' first, it is possible to prevent a contact failure from occurring.

Furthermore, when the cabinet 1 is installed and used in a kitchen or the like, water droplets or the like may adhere to the electrode structure 2. However, in this embodiment, the back surface of the electrode structure 2 is becomes a groove, and a space is created between the edge of the opening of the cabinet 1 and the opening edge of the cabinet 1, so water droplets enter the gap between the edge of the opening of the cabinet 1 and the back surface of the electrode assembly 2 due to capillary action, and the electrode bands 6, 6 It is possible to reduce the possibility of short-circuits caused by gaps between the electrodes and defects in performance, etc.0. Furthermore, FIG. 5 shows another embodiment of the present invention.
The back side of the insulating band 6 has an electrode band 6.6' protruding below the insulating band 6, but a part of the insulating band 5 is flush with the electrode band 6.6. In this case as well, although the effect is inferior to the above, the same effect can be obtained.

Effects of the Invention As is clear from the description of the embodiments described above, the present invention provides a simple and easy connection when an insect repellent electrode structure is disposed on the opening edge of a cabinet or the like and a power source is connected to the electrode structure. It has high stability, and the electrode structure is less likely to be short-circuited by water droplets, making it highly valuable.
