Abstract
The invention discloses a time-base circuit variable frequency ultrasonic wave rat repeller. The rat repeller consists of a 220V alternative current, a power frequency step-down transformer T, a full-bridge rectifier circuit, a differentiating circuit, a variable frequency type oscillator and a transduction circuit. The rat repeller is characterized in that the time-based circuit IC1 in the variable frequency type oscillator selects the model of NE555. The time-base circuit variable frequency ultrasonic wave rat repeller provided by the invention is more stable in rat repelling and prevention effect, is nontoxic, harmless, nonradiative, and has no pollution to the environment; the ultrasonic wave is 46 dB, which is lower than the acceptable value of the human body; people cannot hear the sound, the rat repeller has no influence to the human body, and the purposes of rat repelling and killing are achieved. As rats in different places react differently on the ultrasonic wave frequency, so that the ultrasonic wave frequency emitted by the rat repeller has a certain range when being designed, i.e. a variable frequency ultrasonic wave is emitted without being fixed on one same frequency, so that better rat repelling effect is achieved.
