[0013] By adopting the above technical solution, the filter element can be replaced during the cleaning process by closing the second control valve.

[0014] Optionally, the water pump is fixedly installed between the second filter cartridge and the third filter cartridge.

[0015] By adopting the above technical solution, the circulation speed of the cleaning liquid can be increased by the water pump, and at the same time the third filter cartridge can increase the filtering effect of the cleaning liquid after contacting the water pump.

[0016] Optionally, the three-way joint is located between the third filter cartridge and the liquid inlet, and the drain pipe is fixedly mounted on the three-way joint and passes through the side wall of the cleaning machine body.

[0017] By adopting the above technical solution, the cleaning liquid can be discharged and replaced by opening the first control valve on the drain pipe.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] The technical solution of the utility model can circulate the cleaning liquid in the cleaning pool by starting the water pump. During the circulation process, the cleaning liquid will pass through the first filter cartridge, the second filter cartridge and the third filter cartridge. Since the grades of the filter elements inside each filter cartridge are different, the filtering effect can be increased. The filter element can be replaced by closing the second control valve and opening the sealing cover, thereby increasing the service life of the filter cartridge. BRIEF DESCRIPTION OF THE DRAWINGS
