Description

[Detailed Description of the Invention] Industrial Application Field The present invention is designed to prevent small animals such as cockroaches, which engage in walking activities that are harmful to hygiene, into accommodation rooms such as kitchen furniture, wash basins, and other storage cabinets, as well as living rooms and bathrooms. This relates to an electric insect repellent device that prevents insects from entering living spaces.

Conventional structure and its problems By giving an electric shock to pests such as cockroaches,
The first thing that repels or repels pests is
What is shown in the figure has already been proposed. In this method, a pair of electrodes 10a, 10b are arranged facing each other on an insulating base material 11 with an insulation interval W, and the electrodes 10a,
The voltage of the dry battery 12 is applied between the electrodes 10b, and pests 13 such as cockroaches are
0b, both electrodes 10a, 1
The electric current from 0b flows into the body of the pest 13, thereby causing the pest 13 to receive an electric shock.

If the above configuration is installed, for example, on the outer peripheral wall surface 14a around the article entrance/exit 15 of the storage cabinet 14 shown in FIG.
This can make it difficult for people to enter the storage chamber 14b. In other words, the pest 13 that walks in the direction of arrow A from the outer wall of the cabinet 14,
On the way to the storage chamber 14b, the electrodes 10a, 1
0b, and receives the electric shock and escapes in the direction of arrow B or B' (outward).

However, the pest 13 not only escapes to the outside as described above, but also passes through the electrodes 10a and 10b and
In some cases, they may escape in the direction (inward), and in such a case, they are allowed to enter the accommodation chamber 14b. This largely depends on where the electrodes 10a and 10b are arranged. That is, as shown in FIG.
If a and 10b are placed opposite to the door 16, even if the pest 13 tries to return in the direction of arrow B or B' after receiving the electric shock,
Due to the door 16 being in the way, the user cannot successfully escape to the outside and ends up in the direction of arrow C.

When the electrodes 10a and 10b are installed in a place where there is no door or the like in their relative vicinity, pests 13
It has been confirmed through experiments that after receiving an electric shock, most of them return to the direction in which they were walking (outward).
The electrode 10 is placed in the relative vicinity of b where there is a door 16, etc.
When the electrodes 10a and 10b are provided, there is a case where the above-mentioned inconvenience occurs, and this inconvenience occurs when the insulation interval W between the electrodes 10a and 10b is far from the outer peripheral surface level L of the door 16. The further it is set (toward the accommodation chamber 14b), the higher it becomes. In other words, as the setting position of the insulation interval W moves inward, the part of the pest 13's body that is located within the gap T increases, and it becomes more difficult for the insect to escape to the outside after receiving an electric shock. It is.

OBJECTS OF THE INVENTION An object of the present invention is to reduce the number of cases in which the above-mentioned inconvenience occurs and to more reliably prevent pests from entering the housing chamber.

Structure of the Invention In order to achieve the above-mentioned object, the electric insect repellent device of the present invention provides an electric shock type insect repellent device that includes an opening and an opening/closing body configured to cover the opening and facing the outer peripheral wall surface around the opening. At least one pair of electrodes to which a voltage is applied are disposed facing each other with an insulating interval, and the insulating interval of the electrodes is lower than the center level of the width of the part where the opening/closing body faces the outer peripheral wall. It is configured to be located outside and close to the outer circumferential surface level of the opening/closing body, and this has the advantage of more reliably preventing pests from entering the housing chamber.

DESCRIPTION OF EMBODIMENTS Examples of the present invention will be described below with reference to FIGS. 3 to 7.

Reference numeral 1 denotes a storage body having a storage chamber 2 for storing dishes, people, etc., and although a storage cabinet is shown as an example in this embodiment, it may also be kitchen furniture, a washstand, etc. It may be a building wall that constitutes a living space. Reference numeral 3 denotes an opening formed in a part of the storage body 1, and in the case of a storage cabinet, it is an entrance for taking in and out of stored items, and in the case of a building wall, it is a window or an entrance for people. Reference numeral 4 denotes an opening/closing body such as a door for opening/closing the opening 3, and in this embodiment, it is rotatably mounted via a hinge 4a, but it is conceivable that it can be freely moved vertically or horizontally. . The opening/closing body 4 is sized to face the outer circumferential wall surface 1a around the opening 3, thereby covering the opening 3. Reference numerals 5a and 5b denote a pair of band-shaped electrodes made of a conductive material.
A, they are arranged substantially parallel to each other with a small (about 2 mm) insulating interval W between them, and appropriate means such as adhesives and tackers are used for the arrangement. Further, the insulation interval W portion of the electrodes 5a, 5b is located outward (on the outer surface side of the container 1) from the center level O of the width l of the portion where the opening/closing body 4 faces the outer peripheral wall portion 1a, and It is set to be located near the outer circumferential surface level L of the opening/closing body 4. That is, in the embodiment of FIG.
The insulation interval W portion is set at a position closer to the inside (toward the storage chamber 2 side) by about mm. 6 is electrode 5a, 5b
A commercial power supply or a dry battery is used as a power source for applying voltage to the electrode. In this embodiment, a dry battery is used, and its side is connected to one electrode 5a and the other side to the other electrode 5b via an electric wire 7. . If the voltage of the power supply 6 is about 6V or more, it is possible to give an electric shock to pests 8 such as cockroaches, and of course it can be higher than that, but if the voltage is too high, there is a risk of electric shock to the human body. In a certain place,
Since the electrodes 5a and 5b cannot be arranged, it is optimal to set the voltage to about 30V or less, since this will not cause electric shock to the human body and will give a stronger electric shock to the pests 8. However, the electrode 5a is placed in a place that does not affect the human body.
5b, the voltage may be 100V or more.
Further, when using a commercial power source to obtain a voltage of about 30V, the voltage is lowered using a transformer (not shown).

In the above structure, when a pest 8, such as a cockroach, which has walked on the outer surface of the container 1 as shown by arrow A in FIG. Since the body such as the hind legs or antennae touches the electrodes 5a and 5b, a current flows inside the body of the cockroach 8, and this electric shock causes the cockroach 8 to follow the arrows B, B',
They will escape in either direction C. Arrow B
Alternatively, if the cockroach 8 escapes in the direction B' (outward), the cockroach 8 will not enter the containment chamber 2, but if it escapes in the direction of arrow C (inward), as mentioned in the problem section. This will allow the cockroaches 8 to enter the housing chamber 2. However, in this embodiment, the electrodes 5a, 5
The insulation interval W portion of b is located outside the center level O of the width l of the portion where the opening and closing body 4 faces the outer peripheral wall portion 1a (on the outer surface side of the accommodation chamber 1), and is located on the outer peripheral surface of the opening and closing body 4. Since the electrodes 5a and 5b are set to be located near the level L, the probability of the cockroaches 8 escaping in the direction of the arrow C (inward) can be reduced.

That is, by setting the insulation interval W to the above position, the pest 8 receives an electric shock with its head portion within the gap T between the outer peripheral wall surface 1a and the opening/closing body 4, and in this state, Since the opening/closing body 4 is less of an obstruction, the pests 8 can easily escape in the direction of arrow B or B' (outward).

Figures 5 and 6 show an example in which the insulation interval W is located at approximately the same level as the L level, and Figure 7 shows an example in which the insulation interval W is located at approximately the same level as the L level, and Figure 7 shows an example in which the insulation interval W is located slightly outside the L level (approximately 3 mm) (on the outer surface of the container 1). ), and the insulation interval W
If the part is set outward from the L level, pests 8
Since the pest 8 receives the electric shock while most of its body is located outside the gap T, it is easier for the pest 8 to escape and a higher effect can be obtained.

Note that 9 in FIGS. 6 and 9 indicates a member made of a flexible material such as rubber, and this is attached to the outer peripheral wall surface 1a between the insulation interval W portion and the accommodation chamber 2 or the back surface of the opening/closing body 4. There are
This has the advantage that even if the pest 8 passes through the electrodes 5a and 5b, it is prevented from entering the accommodation chamber 2 by the member 9, and even if it is adopted in the embodiments shown in other figures. good.

Effects of the Invention As is clear from the explanations of the above embodiments, the electric shock type insect repellent device of the present invention allows pests such as cockroaches to escape toward the outer surface of the container after receiving an electric shock. This has the advantage of more reliably preventing pests from entering the room.

Although only one pair of opposing electrodes is shown in each embodiment, a plurality of pairs of opposing electrodes may be provided in addition to this.
