Description

[Detailed Description of the Invention] Industrial Application Fields The present invention is applicable to small animals such as cockroaches, which engage in activities harmful to hygiene, in accommodation rooms such as kitchen furniture, individual storage cabinets, and living spaces such as kitchens, bathrooms, and living rooms. This relates to an electric insect repellent device that prevents insects from entering or approaching.

Conventional structure and its problems In general, cockroaches can easily invade storage furniture, etc.
Insect traps are used, or insect repellent pads are installed at the contact area between the opening and the door.

Although the above described insect traps are somewhat effective because they are placed in the path of cockroaches, they cannot prevent all the cockroaches from entering the storage furniture.

In addition, those that use seals may have slight gaps due to aging, whereas cockroaches may have only one gap.
Insects can invade even if there is a gap of mm, so it cannot be said to be a perfect means of preventing insects.

By the way, cockroaches secrete a sticky substance on the backs of their legs, so if you apply a voltage between the two legs of a cockroach,
Very sensitive to electric shocks.

In the experiment shown below, voltages of various values were applied between the cockroach's two limbs, and the degree of electric shock felt by the cockroach was determined through experimentation.

In the experimental apparatus shown in FIG. 6, numerals 1 and 2 are exposed band-shaped electrodes made of aluminum plate or the like, which are arranged in parallel on an insulating plate 3 with an insulating interval 4 in between.

Further, a DC voltage is applied between the electrodes 1 and 2 by a dry battery 5.

Now, let the cockroach 6 be released on the insulating board 3 and let it walk.
When the cockroach 6 contacts the electrodes 1 and 2 across its two limbs, a DC voltage is applied between the two limbs of the cockroach 6 by the dry battery 5.

Here, the voltage value of the dry battery 5 was varied variously, and the degree of electric shock reaction of cockroaches at each applied voltage value was investigated, as shown in Table 1 below.

(Margins below) Back Table 1 From the above results, it can be seen that cockroaches begin to feel an electric shock at about 6 volts of DC voltage.

Furthermore, when the resistance value between the two legs of a cockroach was experimentally measured, it was about 2 MΩ for the black cockroach and about 1 MΩ for the German cockroach. t.

From the above experiment, since cockroaches begin to react at a voltage of about 6 volts, the current value for black cockroaches is 3 μA.
It can be seen that a single-chambered cockroach can begin to feel an electric shock from a minute current of about 6 μA.

The cockroach electric shock test described above revealed that cockroaches are sensitive to electric shocks, but the next experiment...
In the experimental apparatus shown in Fig. 5, which is arranged on a vertical plane with the electrodes 1 and 2 lines facing the horizontal hole, cockroaches are released below the electrodes 1 and 2 on the insulating plate 3, and the cockroaches are sent across the insulation gap 4. ,
An experiment was conducted at each voltage to determine whether a cockroach could pass across electrodes 1 and 2 when the cockroach was walked above the electrodes 1 and 2.

The results are shown in Table 2 below.

Table 2 As shown above, cockroaches can be made to fall downward by applying an appropriate electric shock, and from this, it is possible to make cockroaches fall downward by applying a voltage of about 10 volts or more for German cockroaches, and about 20 volts or more for black cockroaches. By applying this between the electrodes, it is possible to prevent cockroaches from moving across the electrodes on the vertical plane.

When the cockroaches are given several electric shocks as described above, they eventually stop in front of the electrodes, try to turn back in the opposite direction, and eventually stop trying to get near the electrodes.

This is because by experiencing several electric shocks, the cockroaches acquire a kind of learning effect, visually sensing that 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 electrodes to which no voltage is applied. Therefore, in addition to simply giving an electric shock to cockroaches, such a device can also have the effect of repelling cockroaches by preventing them from coming near the cockroaches.

For this reason, the present inventors provided at least a pair of electrode strips approximately parallel to each other with a small gap in any part of the main body of the storage furniture, etc.
An electric insect repellent device having means for applying a low voltage of 3o volts has been considered.

FIG. 6 shows an example of this, and 7 is a storage furniture main body, which has an opening 8 at the front and a door 9 for opening and closing the opening 8. The opening 80 and the edge 10 have the opening 8
A pair of electrode strips 11.12 are arranged in parallel with each other with a small gap surrounding the electrode strips 11.12, and a low voltage of about 10 volts is applied to these electrode strips 11.12 by a dry battery 13. ing.

In the above configuration, cockroaches that try to enter the opening of the storage furniture main body 7 are
Touches it, receives an electric shock, and falls outward as if flying.

Therefore, cockroaches do not invade the storage furniture main body 7, and the storage furniture can always be kept sanitary. Furthermore, since the insect repellent device is an electric shock type, it is semi-permanent and can effectively exert its insect repellent function at all times.

By the way, the dry battery 13 for power supply gradually wears out due to self-discharge and voltage is gradually applied to it, or due to leakage at the electrode strips 11 and 12, causing a voltage drop.On the other hand, these phenomena are not displayed, so it is not effective. It is not possible to determine whether a voltage is applied to the electrode strips 11.12. Therefore, a problem arises in that the battery is left in a voltage-dropped state, that is, it is used without an insect-proofing function, allowing pest insects 5 to invade.

Purpose of the Invention The present invention takes into account the above-mentioned problems, and provides an electric insect repellent device that notifies when the voltage of a dry battery for power supply drops below the effective voltage, prompts the replacement of the dry battery, and always exhibits an effective insect repellent function. The purpose is to provide

The structure includes a voltage detection device that detects a voltage drop, and an alarm that is activated by a signal from the voltage detection device.
It is possible to maintain an effective electric shock voltage at all times and reliably prevent insects.

It is activated when the voltage of 2o falls close to the lower limit value of 6V effective for electric shock, and the alarm 23 is operated to notify.

In the above configuration, when the voltage of the dry battery 2o approaches 6V, which is the lower limit of the voltage effective for stain attack due to its consumption, the voltage detection device 22 detects this and automatically activates the alarm 23 to notify the user, for example. A buzzer sounds or a lamp lights up to alert you that it is time to replace the dry battery.

This makes it possible to replace the dry battery 20 and always maintain a state in which the insect repellent function does not deteriorate.
