Electronic rat control device

The utility model discloses an electronic rat control device and belongs to the technical field of electronic deratting. The device comprises a desinsectization ultrasonic generator and a rat control ultrasonic generator, wherein the desinsectization ultrasonic generator and the rat control ultrasonic generator generate 30-60 kHz acoustic signals capable of repelling insects and rats at the same time and 20-40 kHz acoustic signals special for repelling rats respectively. The desinsectization ultrasonic generator further comprises a control wave generator body, a scanning wave generator body and an electro-acoustic transducer. The output wave frequency of the desinsectization ultrasonic generator can be adjusted by adjusting the resistance value of a potentiometer in the control wave generator body, so that rats can not generate immunity and the ultrasonic rat control device can be kept effective for a long time. Meanwhile, the desinsectization ultrasonic generator not only can repel rats but also can effectively stimulate the nerve system, cardiac system and auditory system of flying and climbing insects within the controlled range by means of high-frequency ultrasonic waves transmitted through a piezoelectric ceramic piece and a power line. The device is simple in structure, reasonable in design and convenient to maintain and use.
