A Power Circuit Effectively Improving the Effect of Ultrasonic Cleaning

Abstract

The invention discloses a power supply circuit capable of effectively improving ultrasonic cleaning effect. Controllable silicon Q2 is arranged at a main circuit alternating-current input end; an isolating power supply is used for supplying power to a circuit; after passing through a resistor R1 and a resistor R2, supply voltage is output through a PNP type triode Q1 collector electrode, is output to an electrode G of controllable silicon Q2 through a diode D1 and a resistor R4, so that controllable silicon Q2 starts working to conduct; main voltage generates an alternating signal through the controllable silicon Q2 for starting, and the alternating signal is supplied to a main loop; ultrasonic signals PWM1 and PWM2 are pre-amplified at a preceding stage, are amplified in a mode of driving two power tubes by driving a transformer, and are supplied and output to the transformer; after impedance is matched with impedance of an ultrasonic transducer, the ultrasonic transducer works according to the alternating signal, and transversely generates power, so that liquid uniformity is improved; power is transversely generated to drive a liquid, so that fast start oscillation is achieved; and this wave generating way does not easily damage a stainless steel vibrating surface, so that whistlers generated by ultrasonic waves are effectively eliminated.

Description

technical field [0001] The invention relates to cleaning equipment, in particular to a power circuit for effectively improving the effect of ultrasonic cleaning. Background technique [0002] The application principle of ultrasonic cleaning is: the high-frequency oscillation signal sent by the ultrasonic generator is converted into high-frequency mechanical oscillation by the transducer and propagated to the medium, and the ultrasonic waves radiate forward in the cleaning liquid, making the liquid flow Tens of thousands of tiny bubbles are generated, and the tiny bubbles (cavitation nuclei) existing in the liquid vibrate under the action of the sound field. When the sound pressure reaches a certain value, the bubbles grow rapidly and then close suddenly, and shock waves are generated when the bubbles close , generate thousands of atmospheric pressure around it, destroy the insoluble dirt and make them disperse in the cleaning solution, when the group particles are wrapped in...
