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 disposed in a passageway for cockroaches, etc., although some effects can be expected, it cannot prevent all cockroaches etc. from entering the structure. Additionally, 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 1mm, 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 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. It's summery.

For example, cockroaches secrete a sticky substance on the backs of their legs, so it is known that if a voltage of about 10 volts is applied between the two legs of a cockroach, it will receive a severe electric shock. Now, when the cockroach 6 tries 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 ignited in the cockroach 5, and the cockroach 6 receives a violent 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 several electric shocks, the cockroaches acquire a kind of learning effect, visually detecting that something dangerous is present and trying 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 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 the opening 8 of the storage cabinet 7.

By the way, the above-mentioned insect repellent device has a warp of the opening/closing body 11,
Or, due to manufacturing errors, a gap T is created between the opening edge 9 of the storage cabinet 7 and the opening/closing body 11, and the cockroaches 6 enter the storage chamber 12 through the gap T between the storage cabinet 7 and the opening/closing body 11. When trying to do so, the cockroach 6 usually receives an electric shock when it straddles the electrodes 3 and 4 with its two limbs, and in an attempt to escape, it falls into the containment chamber 12 as shown by arrow A.
He escapes outside, but when he receives an electric shock, many parts of his body are destroyed in the storage cabinet 7 and opening/closing body 1.
In some cases, such as intrusion into the housing chamber 12 as shown by arrow B.

OBJECTS OF THE INVENTION The present invention takes the above-mentioned problems into consideration 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 storing objects, an opening of the structure that opens and closes, and is provided so as to face the structure around the opening. A voltage is applied around the opening and closing body, and an opening where the structure and the opening and closing body face each other, and at least one pair of electrodes are arranged facing each other with a small insulation interval, and the electrodes are located inside the structure. The structure is such that one electrode protrudes 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 indicates a storage chamber 14 and an opening/closing body 1 that opens and closes the opening 15 of the storage chamber 14 and is provided to face the mouth edge 16 around the opening 15.
7, the opening 1
An electric insect repellent 18 is attached to the mouth edge 16 surrounding the 5. The electric insect repellent 18 is applied with a voltage of, for example, about 6 to 40 V from a power source 19, and 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). ing. The electrode 22 located inside the storage chamber 14 of the electrodes 21 and 22 is made of a conductive material with a buffering effect, such as conductive rubber or conductive resin, and protrudes from 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 structure, the electrodes 21 and 22 can be arranged 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 warping of the opening/closing body 17 or manufacturing errors. In addition, by protruding the electrode 22 inside the storage chamber 14 and bringing it into contact with or close to the opening/closing body 17, the intrusion of cockroaches 23 and the like into the storage chamber 14 can be reduced. That is, the cockroaches 23 and the like that feel the electric shock and collide with the protruding electrodes may reach the accommodation chamber 14 through the gap T, but most of them bounce back and escape outward as shown by arrow A.

Further, 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. The one shown in Figure 3 is electric insect repellent 1.
8 is attached to the mouth edge 20 of the storage cabinet 13, and the side surface of the opening/closing body 17 is formed to be inclined so that the inner side is closer to the front.

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. 20, and the side surface of the storage cabinet 13 of the electrode 22 is formed to be inclined so as to move inwardly toward the rear, and the top portion thereof abuts the inner end portion of the mouth edge portion 16.

What is shown in FIG. 5 is the electrode 2 of the electric insect repellent 18.
The arrangement of numerals 1 and 22 is the same as in the embodiment shown in FIG. 4, except that the electrode 22 on the side of the opening/closing body 17 is placed on the protrusion 24 provided on 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 the electric shock, they often collide with the protruding electrodes and bounce outward into the structure.
Therefore, the intrusion of cockroaches into the structure can be further reduced.
