The invention discloses a rigid lens ultrasonic cleaning
machine provided with a self-cleaning pipeline. The rigid lens ultrasonic cleaning
machine comprises a housing bracket, a cleaning tank, a suction
system, a
control system and the self-cleaning pipeline; the self-cleaning pipeline comprises a multi-through-
pipe component, a drainage pump and a drainage
pipe component; the multi-through-
pipe component is connected with the cleaning tank, and under the action of the suction
system, water in the cleaning tank circularly flows between the cleaning tank and the multi-through-pipe component and cleans the inner wall and the outer wall of a
rigid endoscope type luminal device; and the draining pump is connected with the multi-through-pipe component, and under the action of the drainage pump, the water in the cleaning tank and
dirt in the
water flow into the drainage pump via the multi-through-pipe component, and are discharged out of a rigid lens ultrasonic cleaning
machine body through the drainage pipe component connected with the drainage pump. No pipeline cleaning is required through idle running regularly, no filter is required to be cleaned and replaced regularly, the rigid lens ultrasonic cleaning machine saves time and labor, the running cost of the rigid lens ultrasonic cleaning machine is reduced, and the activation of the rigid lens ultrasonic cleaning machine is improved.
