According to this, it is possible to visually check whether the pest control is operating normally.

Hereinafter, the principle of the operation of the pest repeller equipped with the field indicator according to the present invention will be described in detail with a block diagram and a circuit diagram.

In addition, since the coupling capacitance between devices is small, there is an advantage that the signal on the output side does not return to the input side. For this reason, when an electrical circuit and a terminal etc. are combined through a photocoupler, the circuit design becomes easy, because it is not necessary to pay attention to the difference of a power supply voltage and the noise which a mechanical part produces.

The photocoupler 310 transmits the pulse signal to the control terminal G of the triac 311, and the triac 311 is "on" or "off" by the pulse signal. When the triac 311 is turned on, AC power is supplied to the transformer (T1) 320 to generate an electromagnetic field.

On the other hand, since the triac 311 may be damaged by voltage spark during on / off operation, in the present invention, RC series circuits C1 and R3 are added to the anode terminal and the cathode terminal of the triac 311. Thus, a circuit for preventing voltage spikes generated by sudden voltage changes is constructed.

In addition, when the user turns on the ultrasonic operation switch 1 provided on the upper part of the insect repellent according to the present invention, the ultrasonic generator as shown in Figures 2 and 3 is operated, the ultrasonic wave is generated below The circuit configuration will be described in detail.

When the ultrasonic wave operation switch 1 is switched on, the AC power delivered from the power supply unit 100 is down-transformed through the mylar capacitor MC3 of the rectifying smoother 200 to be 15V.

That is, the dual oscillation element 423 is a kind of piezoelectric element, and includes oscillation elements 424 and 425 having different natural frequencies inside and outside, and thus different from each other by the oscillation frequency supplied through the connection jack 426. It is configured to generate the ultrasonic waves in the band at the same time.

The piezoelectric element, also called a piezoelectric element, is an electronic element using piezoelectric phenomena caused by piezoelectric elements. Piezoelectric elements are positive and negative in proportion to external forces on both sides of a plate when pressure is applied in a certain direction to a crystal plate of some kind. In this case, a specific crystal plate has inherent vibration, and when the elastic vibration and the electric vibration coincide, the vibration is combined with the piezoelectric force to generate a stronger vibration.
