Abstract
The invention relates to a sweep-frequency type ultrasonic rodent repeller made of time-base circuit 555. The ultrasonic rodent repeller comprises a power-frequency step down transformer, a full bridge rectifier, a sweep-frequency oscillator and a transducer circuit, wherein the sweep-frequency oscillator comprises a differentiating circuit. Since rats which communicate with each other through ultrasonic waves have powerful hearing systems and are very sensitive to ultrasonic waves. Ultrasonic waves generated by an electronic rodent repeller are irritating to the ears of rats and make the brains of rats uncomfortable, so that the rats want to escape from a place covered by the ultrasonic waves without any hesitation, and because of fear, the rats have many syndromes, such as loss of appetite, apocleisis, spasm and the like and event die, and therefore the purposes of repelling rats out of houses, production and life places and the like are achieved. Since rats in different areas have different responses to the ultrasonic waves, the frequency of the ultrasonic waves emitted by the rodent repeller is designed to be in a certain range, namely the ultrasonic waves emitted by the rodent repeller are sweep-frequency type ultrasonic waves, instead of ultrasonic waves with a fixed frequency; therefore the sweep-frequency type ultrasonic rodent repeller has good rodent repelling effect.
