Description

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

Taking advantage of the ecological habits of similar insects, such as ants, to prevent these insects from entering structures that house items such as food, such as storage cabinets, food storage, bathrooms, houses, etc. This invention relates to an insect repellent device.

Conventional configurations and their problems In general, this type of device is easy for insects such as cockroaches to enter, so a trap is used or a trap is installed at the contact area between the opening and the door to prevent intrusion. ing. 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. Additionally, devices that use nokutsukin 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 11+Im, so it cannot be expected to be effective as a means of preventing intrusion. By the way, the electric insect repellent shown in FIG. 6 is known. This insect repellent includes an insulating base material 1, a pair of electrode bodies 3.4 arranged in parallel on its upper surface with a gap of 2, and a dry battery 6.4 for applying a voltage between the electrode bodies 3.4. ! : Snarling.

For example, it is known that cockroaches secrete sticky substances on the soles of their legs, so that when a voltage of about 10 volts is applied between the two legs of a cockroach, the cockroaches receive a severe electric shock. Here, the cockroach 6 is now trying to move on the floor, and its legs cross the interval 2, causing the electrode body 3.
When the cockroach 6 touches the surface, a voltage is applied to the cockroach 6, and the cockroach 6 receives a severe electric shock and jumps away.After experiencing this several times, the cockroach will eventually move to the electrode body 3°4.
It stands up right in front of 9, tries to turn back in the opposite direction to the direction it was traveling, and finally becomes reluctant to approach the vicinity of the electrode bodies 3 and 4. This is caused by experiencing several electric shocks.
This is because cockroaches acquire a kind of learning effect, visually sensing when something dangerous is present and trying 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. So, with such a device, cockroaches are simply given an electric shock? In addition to trying to stop the progress by giving it to them, you can also expect it to have the repellent effect of not allowing people to approach the area.

The present inventors have considered installing the electric insect repellent described above, which is effective as an insect repellent, in a structure having an opening and an opening/closing body. For example, as shown in FIG. 7, an electric insect repellent 10 is attached to the edge 9 of an opening 8 of a storage cabinet 7.

By the way, in the above-mentioned insect repellent device, a gap T is created between the mouth edge 9 of the storage cabinet 7 and the opening/closing body 11 due to warping of the opening/closing body 110 or a manufacturing error, and the cockroaches 6 are trapped between the storage cabinet 7 and the opening/closing body 11. When the cockroach 6 tries to enter the containment chamber 12 through the gap T, it usually receives an electric shock when it straddles the electrodes 3 and 4 with its two limbs.
In an attempt to escape from it, he runs away from the containment chamber 12 as shown by arrow A, but when he receives an electric shock, his body loses %

In some cases, such as when the ID was intruding between the ID and the storage room 12, as shown by arrow 1B, the ID was intruded into the containment chamber 12.

OBJECTS OF THE INVENTION The present invention takes into account the above-mentioned problems and aims to provide an insect repellent device that can more reliably exhibit its insect repellent effect.

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, an opening of this structure that opens and closes, and is provided so as to face a structure with one opening. A voltage is applied to an opening/closing body in which the opening/closing body and the opening/closing body face each other, and at least one pair of electrodes are arranged facing each other with a small insulation interval, the electrodes are arranged inside the configuration. The structure is such that one electrode is protruded from the other electrode and comes into contact with or approaches the opening/closing body or the structure, and this has the advantage that the intrusion of cockroaches and the like into the structure can be further reduced.

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

In the figure, reference numeral 13 denotes a storage cabinet having a storage chamber 14 and an opening/closing body 17 that opens and closes the opening 15 of the storage chamber 14 and is provided so as to face the mouth edge 16 around the opening 16. An electric insect repellent 18 is attached to a rim 16 surrounding the opening 15. The electric insect repellent 18 is the power supply part 1
A voltage of, for example, about 6 to 40 V is applied to the electrode 9, and it is composed of a pair of electrodes 21 and 22 arranged substantially parallel to each other with a small insulation interval 20 (about 2 mm) between them. The electrode 21. The electrode 22 located inside the housing chamber 14 is made of a conductive material with a buffering effect, such as conductive rubber or conductive resin, and protrudes beyond the other electrode 21 and comes into contact with the opening/closing body 17. 23 is a cockroach.

In the insect repellent device having the above configuration, even if a gap T is generated between the mouth edge 16 of the storage cabinet 13 and the opening/closing body 17 due to a reaction of the opening/closing body 17 or a manufacturing error, the electrode 21.
22' (i) and the electrode 22 inside the storage chamber 14 is protruded and brought into contact with or close to the opening/closing body 17, which can reduce the intrusion of the goya 23 etc. into the storage chamber 14. In other words, the goya 23, etc. that felt the electric shock and collided with the protruding electrode,
In some cases, they end up inside the storage chamber 14, but in most cases, they bounce back like an arrow and escape to the outside.

Furthermore, since the protruding electrode 22 is made of a conductive material that has a buffering effect, it is possible to provide a buffer when the opening/closing body 17 is closed.

3 to 5 all show other embodiments of the present invention. In the one shown in FIG. 3, an electric insect repellent 18 is attached to the opening edge 2o of the storage cabinet 13, and the side surface of the opening/closing body 1a is inclined so as to be located inwardly.

In the device shown in FIG. 4, one electrode 21 of the electric insect repellent 18 is arranged at the outer corner of the mouth edge 16 of the storage cabinet 13, and the other electrode 22 is placed on the opening/closing body 17 facing the mouth edge 16 with a small insulation gap. The side surface of the storage cabinet 13 of the electrode 22 is formed so as to be inclined inwardly and backwardly, and the top part is arranged at the mouth edge part 1.
It abuts on the inner end of 6.

The arrangement of the electrodes 21 and 22 of the electric insect repellent 18 shown in FIG. 6 is the same as that of the embodiment shown in FIG.
The electrode 22 on the opening/closing body 17 side is arranged on the protrusion 24 provided in the opening/closing body 17.

Although the above embodiments have all been described using storage cabinets as an example, the present invention is not limited to this, and can be applied to structures such as bathrooms and houses.

Effects of the Invention As is clear from the description of the embodiments above, the insect repellent device of the present invention has a structure in which the electrode located inside the structure protrudes from the other electrode and contacts or approaches the opening/closing body or the structure. Therefore, after the cockroaches feel an electric shock, they often collide with the protruding electrodes and bounce outwards into the structure, thereby reducing the possibility of cockroaches entering the structure.
