The salvaged impurities will remain on the first filter screen and the second filter screen, and water will drip into the purification tank through the filter screen, and then the knob is turned in sequence. The rotation of the knob drives the rotation of the first threaded rod, so that the bottom end of the first threaded rod releases the fixation of the first filter screen and the second filter screen, and the first filter screen and the second filter screen can be pulled out by hand. The material of the first filter screen and the second filter screen can be selected according to actual needs, and the motor is a stepper motor.

[0017] The beneficial effects of the present invention are:
