Description
Technical field
The utility model relates to a kind of rat destruction device, particularly a kind of full-automatic sweep-frequency B ultrasonic electronic mouse driving device.
Background technology
The ultrasonic rat repellent of Xiao Shouing in the market, mainly form by sample of signal amplifying circuit, multi-resonant oscillating circuit, circuits for triggering and transducer, wherein, sampled signal drives transducer through circuits for triggering again and sends ultrasonic through multi-resonant oscillating circuit production burst oscillator signal; But its ultrasonic waves transmitted frequency band is narrower, and frequency is relatively stable and certain periodicity is arranged, and mouse is easy to adapt to the interference of this frequency band; Hyperacoustic energy is low simultaneously, decay is fast, uses ultrasonic acceptance test instrument to test, and just can not detect ultrasonic in distance place far away slightly and exist.Therefore, this ultrasonic rat repellent is using the initial stage effect obvious, and through after a while, mouse just can adapt to this frequency band, and mouse driving device also loses its rat destruction function.
Summary of the invention
The purpose of this utility model is to provide a kind of frequency band broad, and the automatic irregular variation of frequency, the slow ultrasonic rat repellent of decay, to overcome the weak point of existing mouse driving device.
The technical solution adopted in the utility model: a kind of full-automatic sweep-frequency B ultrasonic rat repellent, comprise sample of signal amplifying circuit, multi-resonant oscillating circuit, circuits for triggering and energy parallel operation, it is characterized in that, also comprise signal selecting circuit and push-pull amplifier circuit, wherein, signal selecting circuit is made up of integrated circuit CD4017 and diode D1～D8, adjustable resistance R1～R8, forms 8 tunnel circulation outputs, is connected between sample of signal amplifying circuit and the multi-resonant oscillating circuit; Push-pull amplifier circuit is made up of two PNP transistors and two NPN transistors, is connected between circuits for triggering and the transducer.
The beneficial effects of the utility model: according to the life habit of insects such as mouse, the physiological property of auditory system, and critical protection life characteristic such as troop, the utility model utilizes ultrasonic to drive muroid, this mouse driving device can send the wave of oscillation of 25k～irregular variation of 70kHz high frequency, to stimulate nervous centralis and the auditory system of mouse, it can't be stood, feel panic uneasy and flee from that effect is permanently effective and safe and reliable.
