Abstract

PURPOSE:To exterminate cockroach in high efficiency without staining the hands, etc., by generating ultrasonic output with plural oscillation circuits having different oscillation frequencies, driving an ultrasonic vibrator with superposed oscillation outputs and radiating ultrasonic wave. CONSTITUTION:The oscillation outputs of a plurality of oscillation circuits 1, 2 energized with a battery 7 and oscillating at different frequencies are mixed and superposed with diodes D1, D2, etc. An ultrasonic vibrator 4 is driven by the superposed oscillation output through a driving circuit 3 to radiate an ultrasonic wave from the ultrasonic vibrator 4. An ultrasonic wave is continuously radiated over a wide area around the vibrator to prevent the approach of cockroach. Accordingly, the extermination of cockroach can be carried out cleanly without staining the hands. Since the device is integrated with a case 5 holding the battery 7, it has beautiful appearance.

Description

[Detailed Description of the Invention] [Industrial Application Field] Conventionally, cockroaches are often exterminated by spraying a spray set insecticide.

Alternatively, a paper board or the like coated with a strong adhesive agent is placed in the path of cockroaches to catch cockroaches that try to pass through, and the paper board is disposed of by incineration or otherwise.

[Problems to be solved] However, the former extermination method using a spray set of insecticides has the problem that it is completely ineffective unless it is sprayed immediately after cockroaches are discovered, and that it is not effective when spraying cockroaches on food or tableware, such as in the kitchen. If insecticides are sprayed when they appear nearby, food and tableware will be exposed to the insecticide, which can have a negative impact on human health. In addition, the Flocica 1 contained in the insecticide spray kit destroys the ozone layer surrounding the earth, making it unable to protect against ultraviolet rays from the sun (and causing serious damage to living things on earth). In recent years, it has begun to be pointed out that there are also problems that could lead to irreversible situations.

In addition, with the latter method of trapping cockroaches using a strong adhesive agent, it is not recommended to place such a chemical in areas such as the kitchen where cleanliness is most expected, and it is not advisable to leave the agent in place until some cockroaches have been trapped. If left untreated, there is a problem in that some of them will rot and become unclean.

Furthermore, both have the common problem that they are not effective at all unless cockroaches appear, and the problem that they have to be disposed of by spraying insecticides or holding paper boards with captured cockroaches. be.

[Means for solving problems]

The present invention has been made to solve the above problems, and includes a battery, two or more oscillation circuits that each oscillate at a different frequency, a synthesis circuit that synthesizes the oscillation outputs of these oscillation circuits, Means comprising: an ultrasonic sounding body that is driven by the oscillation output synthesized by the synthesis circuit to generate ultrasonic waves, and a case that houses the battery 1 oscillation circuit 9 synthesis circuit and the ultrasonic sounding body. We took the following steps.

[For production]

In the cockroach exterminator according to the present invention, ultrasonic vibrations are oscillated by two or more oscillation circuits, their oscillation outputs are combined by a combination circuit, and the combined oscillation output drives an ultrasonic sounding body.

And since this ultrasonic sounding body emits ultrasonic waves,
In order to avoid the ultrasonic waves, cockroaches run away to places where they cannot be affected.

Moreover, since the two or more oscillation circuits oscillate at different frequencies, the above effect is further enhanced.

All of the above circuits are operated by batteries, and all of these components are built into the case.

〔Example〕

Hereinafter, preferred embodiments of the cockroach exterminator according to the present invention will be described in detail based on the drawings.

FIG. 1 is a block diagram of the electronic circuit of the embodiment, FIG. 2 is a circuit diagram of an example of the electronic circuit, and FIG. 3 is a perspective view of the case of the embodiment.

In FIG. 1, the oscillation outputs of the first ultrasonic oscillation circuit and the second ultrasonic oscillation circuit 2 are provided by a diode DI.

They are mixed at D2, and the ultrasonic sounding body 4 is driven via the drive circuit 3 to diffuse the ultrasonic waves around.

FIG. 2 shows an example of a circuit diagram in which the electronic circuit is constructed of integrated circuit elements. Here, an integrated circuit element having six inverter elements in one integrated circuit element package was used, so an electronic circuit was realized with only one active element and some electronic components. If an LS type TTL, IC or CMO3, IC is used as this integrated circuit element, power consumption is low, so that it can be operated continuously for a long time with a small battery.

Here, two sets of oscillation circuits are used, but in order to increase the extermination effect, three or more sets of oscillation circuits that oscillate at different frequencies may be combined in addition to the two sets.

In FIG. 3, a case 5 houses therein a printed circuit board 6 for an electronic circuit having the above structure, a battery 7, and the ultrasonic sounding body 4. Reference numeral 8 denotes a slit for diffusing the ultrasonic waves emitted from the ultrasonic sounding body 4 to the surroundings.

In the cockroach exterminator having the above configuration, when the switch provided on the bottom of the case 5 is turned on, the electronic circuit starts operating, and the ultrasonic waves emitted from the ultrasonic sounding element 4 are transmitted through the slit 8 all around the circumference. spread to.

If this cockroach exterminator is placed in a kitchen or the like, even if cockroaches try to approach the surroundings, the ultrasonic waves will continue to be spread over a wide area around the cockroach exterminator, making it impossible to respond.

If you keep the cockroach exterminator in operation all the time, there will be no cockroaches around it, and eventually,
There is no need to constantly operate this cockroach exterminator.

In this way, according to the cockroach exterminator of the present invention, cockroaches can be exterminated without getting one's hands dirty.

[Effects] As described above, the cockroach exterminator according to the present invention continues to diffuse ultrasonic waves over a wide area around the device,
It keeps cockroaches away, so you can get rid of cockroaches cleanly and without getting your hands dirty.

Moreover, since it is integrated into a case with a built-in battery, it does not disturb its aesthetic appearance and can be placed in a desired location and operated continuously for a long period of time.
