Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention utilizes the ecological habits of cockroaches, ants, and other similar insects that engage in crawling activities that are harmful to hygiene. The present invention relates to an insect control device for preventing insects from entering structures containing foods, such as storage cabinets, food storages, bathrooms, houses, etc.

Conventional structure and its problems In general, this type of device is easy for insects such as cockroaches to enter, so a trapping device is used or a gasket is installed at the contact area between the opening and the door to prevent intrusion. . Since the trapping device is placed in a passageway for cockroaches, etc., although it is somewhat effective, it cannot prevent all cockroaches etc. from entering the structure. In addition, products that use packing may leave small gaps due to deterioration over time, and on the other hand, cockroaches can invade even if there is a gap of just 1 mm, so it cannot be expected to be effective as a means of preventing intrusion. .

By the way, as an electric insect repellent device, one shown in FIG. 6 is known. This insect repellent device consists of an insulating base material 1, a pair of electrode bodies 3 and 4 arranged in parallel on the upper surface thereof with a gap 2, and a dry battery 5 that applies voltage between the electrode bodies 3 and 4. There is.

For example, cockroaches are known to have a sticky substance secreted on the backs of their legs, so if a voltage of about 10 volts is applied between their legs, they will receive a severe electric shock. Now, when the cockroach 6 is trying to move on the floor and its legs cross the gap 2 and touch the surfaces of the electrode bodies 3 and 4, a voltage is applied to the cockroach 6, and the cockroach 6 receives a severe electric shock. It jumps up and down. After experiencing this several times, the cockroach will eventually move to the electrode bodies 3 and 4.
It stops in front of it, tries to turn back in the opposite direction to the direction it was traveling, and finally stops trying to get near the electrode bodies 3 and 4. This is because by experiencing electric shock several times, cockroaches acquire a kind of learning effect, and they visually sense that something dangerous is there and try to defend themselves.
This can be seen from the fact that it reacts similarly to another material made of the same material as the electrode body to which no voltage is applied. Therefore, such a device can be expected to have the effect of repelling cockroaches by preventing them from coming near the cockroaches, in addition to simply giving an electric shock to the cockroaches to prevent them from advancing.

The present inventors have considered installing the above electric insect repellent, which is effective as an insect repellent, in a structure having an opening. For example, as shown in FIGS. 7 and 8, a strip-shaped electric shock preventer 9 is placed around the opening 8 of the storage cabinet 7 by means such as V-cutting and bending, and the ends are butted together. or the 9th
As shown in the figure, four strips of electric insect repellent 9 are arranged in order around the opening.

By the way, since the storage cabinet 7 and the electric insect repellent 9 are subject to manufacturing errors, the length of the electric insect repellent 9 is set slightly shorter than the required dimensions of the placement surface to avoid overlapping, and sometimes As shown in FIGS. 8 and 9, there is a possibility that a gap T of about 5 mm may occur in the abutting portion 10.

However, adults and larvae such as German cockroaches exist with a body length of about 2 mm, and there was a risk that they could invade through the proximal gap without receiving an electric shock, so this was a step forward as an insect repellent. .

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned problems and aims to provide an insect repellent device with a higher insect repellent function.

Structure of the Invention In order to achieve the above-mentioned object, the insect repellent device of the present invention includes a structure for accommodating objects, a band-shaped electric insect repellent placed around an opening of the structure with their ends abutted against each other, and The insect repellent device is supplied with voltage from a power source, and consists of at least a pair of electrode bodies placed opposite each other with a small insulation gap, and an auxiliary device on the back side of the abutted portion that connects the electrodes of the same polarity to each other for electrical conduction. Description of an embodiment in which an electrode is disposed, and even if a gap occurs in the butt part of the electric insect repellent device, the auxiliary electrode is exposed, so that a reliable insect repellent function can be achieved. An embodiment will be described based on FIGS. 1 to 4.

In the figure, reference numeral 11 denotes a storage cabinet that has an opening 12 and a housing section 13 inside, and a strip-shaped electric insect repellent 15 is V-cut and folded into a lip 14 surrounding the opening 13. It is arranged by means of bending, and is attached and arranged so that its ends abut against each other. The electric insect repellent 15 is constructed by applying a voltage of, for example, about 6 to 40 V from a power source 16, and using a pair of resin parts integrated by extrusion molding or the like with a small (about 2 mm) resin insulating part 17 interposed therebetween. It consists of manufactured electrode bodies 18 and 19. On the back side of the abutting part 20 of the electric insect repellent 15, auxiliary electrode bodies 21 and 22, which are set larger than the expected gap of the abutting part 20, are disposed in contact with the electrode bodies 18 and 19 at a distance of 23,
In addition, terminals of the power supply unit 16 are connected to the auxiliary electrode bodies 21 and 22. Reference numeral 24 is designed to fix the ends of the electric insect repellent 15 to the storage cabinet 11 without shifting their positions, and the auxiliary electrode bodies 21 and 2
2 and the electrode bodies 18, 19 of the electric insect repellent 15 using a tack needle made of a conductive material to ensure continuity between the electrode bodies 18, 19 of the electric insect repellent 15.
9 and auxiliary electrodes 21 and 22 are punched out and driven into the storage cabinet 11 and fixed.

The insect repellent device having the above configuration includes an auxiliary electrode body 21 which is connected to the back surface of the abutting part 20 of the electric insect repellent tool 15 and is electrically connected to the electrode bodies 18 and 19 by straddling the same polarity.
22, storage cabinet 1
1, or a dimensional error occurs in the manufacturing of the electric insect repellent 15, and the butt part 2 of the electric insect repellent 15
Even if there is a gap T as shown in FIG. By disposing the tool 15, the insect repellent function can be reliably exhibited.

In the above embodiment, the auxiliary electrode bodies 21 and 22 were separated into two parts, but as shown in FIG. In the above embodiment, the terminals of the power supply section 16 are connected to the auxiliary electrode bodies 21 and 22, but as shown in FIG.
The terminal of the power supply section 16 may be connected to the side.

Furthermore, although the above embodiments have been described using a storage cabinet as an example, the present invention is not limited to this, and can be applied to structures with openings such as bathrooms and houses.

Effects of the Invention As is clear from the description of the embodiments described above, the insect repellent device of the present invention has an auxiliary electrode body arranged on the back side of the abutting part of the electric insect repellent device, which conducts contact across electrode bodies of the same polarity. Therefore, even if there is a gap between the abutting parts of the electric insect repellent, the auxiliary electrode is exposed through the gap, and a reliable insect repellent function can be achieved, which is of great value.
