Description

[Detailed Description of the Invention] Industrial Application Fields The present invention is useful for storing small animals such as cockroaches, which engage in crawling activities that are harmful to hygiene, in accommodation rooms such as kitchen furniture and other 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 Structures and Problems Generally, the structure shown in FIG. 5 has already been proposed as a device that applies an electric shock to pests such as cockroaches to repel or avoid insect repellents.
In this method, a pair of electrodes 1 and 2 are arranged facing each other on an insulating base material 4 with an insulation interval 3, and a voltage from a dry battery 5 is applied between the electrodes 1 and 2, and pests 6 such as cockroaches are When placed across both electrodes 1 and 2, an electric current flows into the body of the pest 6, whereby the pest 6 receives an electric shock.

If the structure described above is installed on the front wall 9 of the storage cabinet 7 around the article loading/unloading opening 8, as shown in FIG. 6, for example, pests can be prevented from entering the storage chamber 10.

By the way, if the electrodes 1 and 2 become dirty, their insect repellent function will be reduced, so it is preferable to clean them regularly.

However, there was a problem in that if the electrodes 1 and 2 were removed with a wet cloth or the like while a voltage was applied between them, the surfaces of the electrodes 1 and 2 would be electrolytically corroded and deteriorated.

Therefore, the inventors of the present invention considered installing an "on" and "off" switch 11 between the electrodes 1 and 2 and the dry battery 5 serving as the power source, as shown in FIG.

That is, when cleaning the electrodes 1 and 2, the switch 10 is turned off to prevent electrolytic corrosion from occurring.

However, there was a problem in that the user sometimes forgot to turn the switch 11 back on after cleaning, allowing vermin to enter the storage chamber 10.

OBJECTS OF THE INVENTION The present invention takes into consideration the above-mentioned problems and aims to provide an insect repellent device that can always exhibit its insect repellent function.

Structure of the Invention In order to achieve the above object, the electric shock type insect repellent device of the present invention applies voltage from a power supply section, and
At least one pair of electrodes arranged opposite to each other with a small insulation interval, a notification device electrically connected in parallel with the electrodes, and energization of the notification device and the electrode arranged between the connection between the notification device and the power supply section. This configuration is equipped with a changeover switch that switches between the two, and has the effect of constantly exhibiting its insect repellent function.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

In the figure, reference numeral 12 denotes a storage cabinet having a storage chamber 13 for storing tableware, food, etc.A pair of electrodes 15 and 16 made of a conductive material in the form of a band are attached around the article loading/unloading opening 14 using an adhesive.
It is arranged by suitable means such as a tack car. The electrodes 15 and 16 are arranged substantially parallel to each other and facing each other with a small (approximately 2 mm) insulation interval 17 therebetween. Reference numeral 18 denotes a power supply unit that applies voltage between the electrodes 15 and 16, and in this embodiment, a dry battery is used.
If the voltage of the power supply section 18 is about 6 volts or more, it is possible to give an electric shock to pests such as cockroaches, but if the voltage is too high, there is a risk of electric shock to the human body, so it should be about 30 volts or less. It is preferable to do so. Reference numeral 19 denotes a notification device such as a neon lamp or a buzzer, which is electrically connected in parallel with the electrodes 15 and 16. Reference numeral 20 denotes a change-over switch for switching energization to the notification device 19 and the electrodes 15 and 16, and is arranged between the connection between the notification device 19 and the power source section 18. Reference numeral 21 denotes an opening/closing body for opening and closing the storage chamber 13, which is a door in this embodiment.

In the above configuration, when cleaning the electrodes 15 and 16, the changeover switch 20 is switched to the notification device 19 side. Then, since no voltage is applied between the electrodes 15 and 16, electrolytic corrosion will not occur in the electrodes 15 and 16 even if the electrodes 15 and 16 are wiped with a wet cloth or the like. At the same time, since the notification device 19 is activated, the user is notified that no voltage is being applied to the electrodes 15 and 16, and the changeover switch 20 is returned after cleaning.
There is no fear of forgetting to switch to the side where voltage is applied between electrodes 15 and 16, and voltage can be reliably applied between electrodes 15 and 16, so that a predetermined insect repellent function can always be exhibited.

3 and 4 both show other embodiments of the present invention. The one shown in FIG. 3 is the electrode 15,1.
6 is arranged on the opening/closing body 21 side.

In the case shown in FIG. 4, one electrode 15 is attached to the storage cabinet 12 side, and the other electrode 16 is arranged on the opening/closing body 21 side at a level located inward from the level of the one electrode 15.

Although the above embodiment shows an example in which the electrodes 15 and 16 are arranged around the article loading/unloading port 14 of the storage cabinet 12, the electrodes are not limited to this, and can be placed in the corner of a room where cockroaches and the like often infest, or near furniture. Another method is to place electrodes in crevices of furniture so that cockroaches can easily come into contact with them. In this case, it is possible to obtain an effect (repellent effect) of making it difficult for cockroaches and the like to approach the vicinity of the installation part.

Also, as a power source for applying voltage, 6 to 30 volt dry batteries are advantageous in terms of safety, etc.
It is not necessarily limited to this, and the AC voltage may be applied from an outlet attached to the room.

Effects of the Invention As is clear from the description of the embodiments above, the insect repellent device of the present invention is configured so that the alarm device is activated when the electricity to the electrode is cut off during cleaning, etc. There is no danger of forgetting to return the changeover switch to the side where the electrode is energized, and therefore the insect repellent function can always be exerted.
