After the contact, the power of the electromagnet 31 is turned on, and the electromagnet 31 adsorbs the second main gear 665. Under the elasticity of the spring 666, the second main gear 665 leaves the second slave gear 661, so that when the inner wall of the configuration tank is cleaned, the screw sleeve driving assembly 66 will not interfere with the cleaning work;

[0047] When the second main gear 665 leaves the second slave gear 661, the rotation of the first main gear 54 will drive the first slave gear 51 meshed therewith to rotate, and the first slave gear 51 drives the limiting tube 61 to rotate, and the limiting tube 61 drives the telescopic cleaning brush handle 63 to rotate, so that the bristles 634 wipe and clean the inner wall of the configuration tank;

[0048] When the bristles 634 are wiping and cleaning, water is introduced into the rotary joint 52, and the water is sprayed out from the flushing nozzle 67 through the limiting tube 61 to clean the inner bottom side of the configuration tank. At the same time, the water enters the hollow bar 633 through the limiting cylinder 631 and the moving cylinder 632, and then is sprayed out from the water outlet hole 635 on the hollow bar 633 to the inner wall of the configuration tank, thereby improving the cleaning effect of the inner wall of the configuration tank.
