Description

[Detailed description of the invention] Industrial applications The present invention relates to cockroaches whose crawling activities are harmful to hygiene.

Utilizes the ecological habits of similar insects such as ants to prevent these insects from entering structures that house articles 2, such as food, such as storage gear vignettes, food storage, bathrooms, houses, etc. This invention relates to an insect repellent device.

Conventional Structures and Problems In general, devices of this type are susceptible to intrusion by insects such as cockroaches, so a trapping device is used or a gasket is provided at the contact area between the opening and the door to prevent intrusion. Since the trapping device is disposed in a passageway for cockroaches, etc., although some effects can be expected, it cannot prevent all cockroaches etc. from entering the structure. However, products that use packing may leave small gaps due to deterioration over time, and on the other hand, cockroaches and the like can invade even if there is a gap of only 11M1, so this method cannot be expected to be effective as a means of preventing intrusion. be.

By the way, there is a known electric insect repellent as shown in Fig. 6. This insect repellent includes an insulating base material 1, a pair of electrode bodies 3 arranged in parallel on the upper surface with a gap 2,
4, and a dry battery 5 that applies voltage between the electrode bodies 3 and 4.
It's getting better.

For example, cockroaches are known to have a sticky substance distributed on the backs of their legs, so if you try to apply a voltage of about 10 volts between the two legs of a cockroach, it is known to receive severe electric shock. Here, when the cockroach 6 is about to move on the floor and its legs cross the interval 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 violent electric shock and jumps. After experiencing this several times, the cockroach eventually stops in front of the electrode bodies 3 and 4, tries to turn back in the opposite direction to the direction in which it was traveling, and finally stops trying to approach the vicinity of the electrode bodies 3 and 4.

This is because by experiencing several electric shocks, cockroaches gain 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 other materials made of the same material as the electrode body to which no voltage is applied. Therefore, with such a device, in addition to simply applying an electric shock to the cockroaches to prevent them from advancing, it is also possible to expect a repellent effect of preventing cockroaches from approaching the cockroaches.

The present inventors have considered installing the electric insect repellent described above in a structure having an opening, which is effective as an insect repellent means. For example, as shown in FIGS. 7 and 8, the storage cabinet 7
A belt-shaped electric shock preventive device 9 is installed around the opening 8 of the device by means such as V-cutting and bending, and the end portions are butted against each other, or As shown in the figure, four strip-shaped electric insect repellents 9 are arranged in order around the opening.

By the way, in order to prevent errors in manufacturing the storage cabinet 7 and the electric insect repellent 9, the length of the electric insect repellent 9 is set slightly shorter than the required dimension of the arrangement surface to avoid overlapping. 8 and 9 as '
As shown in the figure, there is a possibility that a gap T of about 50 mm may be formed at the butt part 10, but adults and larvae of German cockroaches and the like exist with a body length of about 2 mm.
There was a risk that stains could get into the gap without being shocked by the insects, and the insect repellent function was inadequate.

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

Structure of the Invention In order to achieve the above-mentioned object, the insect repellent device of the present invention comprises a structure for storing objects, etc., and a band-shaped electric insect repellent device disposed with its end abutting against the opening of the structure, The electric insect repellent device is made up of at least a pair of electrode bodies arranged opposite each other with a small insulation gap, and a contact conduction is applied across the electrodes of the same polarity on the back side of the abutting part. This structure allows an auxiliary electrode to be disposed to expose the auxiliary electrode even if a gap occurs between the abutting parts of the electric insect repellent, so that a reliable insect repellent function can be achieved.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, reference numeral 11 has an opening 12 and an accommodating portion 13 inside.
This is a storage cabinet that constitutes a storage cabinet, in which a strip of electric insect repellent 16 is placed on the rim 14 surrounding the opening 13 by means of V-cutting and bending, and the ends are butted against each other. The installation is arranged accordingly. The electric insect repellent 15 has a pair of electric insect repellents that are applied with a voltage of, for example, about 6 to 40 V from a power source 16, and that are integrated by extrusion molding or the like with a resin insulating part 17 of a small amount (approximately 2 times) interposed. It is composed of resin electrode bodies 18 and 19.

On the back side of the abutting part 20 of the electric insect repellent 15, auxiliary electrode bodies 21.22, which are set larger than the expected gap of the abutting part 20, are attached to the electrode bodies 18, 19 with an interval 23.
The auxiliary electrode bodies 21 and 22 are connected to the terminals 1 and 0 of the power supply unit 16. 24 is a cabinet 1 that stores the ends of the electric insect repellent 15 without shifting their positions.
1 and to ensure continuity between the auxiliary electrode body 21.22 and the electrode body 18.19 of the electric insect repellent 16.
Electrode bodies 18, 19 and auxiliary electrodes 21, 22 are punched out from the front surface of the housing cabinet 11 and fixed therein.

The insect repellent device having the above configuration has auxiliary electrode bodies 21 and 22 disposed on the back side of the butt part 20 of the electric insect repellent tool 15 to bring the same polarity of the electrode bodies 18 and 19 into contact conduction. , l-11, or electric insect repellent 15
Even if a dimensional error occurs in the manufacturing of the electric insect repellent 15 and a gap T is created at the butt part 20 of the electric insect repellent 15 as shown in FIG. The opening 12'' of the storage cabinet 11 is arranged with an electric insect repellent 15 in the form of a loop with a large gap, so that the insect repellent function can be reliably exerted.

In the above embodiment, the auxiliary electrode bodies 21 and 22 are not only separated into two parts, but also the auxiliary electrode bodies 21 and 22 are separated by means of extrusion molding with a resin insulating part 23 interposed therebetween as shown in FIG.
1.22 may be integrated.Also, in the embodiment described above, the terminal of the power supply section 16 is connected to the auxiliary electrode body 21.22, but as shown in FIG. 1
The terminal of the power supply unit 16 may be connected to the 8.19 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 any structure having an opening, such as a bathroom or a house.

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 disposed on the back side of the abutting part of the electric insect repellent device, which connects the electrode bodies of the same polarity to each other in one circuit. Therefore, even if there is a gap between the butt parts of the electric insect repellent, the auxiliary electrode is exposed through the gap, and the insect repellent function can be reliably performed, which is of great value.
