The invention discloses a down cleaning device, comprising a cleaning bucket body and a screening bucket, wherein a
servo motor is arranged at the center position of the top surface of the cleaning bucket body, a rotating rod is welded through the bottom surface of the
servo motor and a stirring
paddle is welded on the surface of the rotating rod. In this invention, the ultrasonic clean mechanismis provided, An ultrasonic clean mechanism is provided with an ultrasonic high-frequency oscillator inside that ultrasonic clean mechanism, Applying ultrasonic principles, generate
high frequency oscillatory waves, causing a large number of tiny bubbles between the
water flow and the down, By utilizing the pneumatic
shock wave generated when the bubble bursts, the
dirt and the down are thoroughlyseparated, the washing work is automatically completed, the detergent is not needed, the environmental
pollution is improved, a large amount of down can be washed quickly in the same time, the washingefficiency of the down is greatly improved, and the rinsing frequency of the down is reduced because the detergent is not needed, and the precious
water resources are saved.
