After the filter cartridge 5 is cleaned, the installation and positioning can be performed by performing the reverse operation of the above-mentioned disassembly steps.

[0025] The transverse movement assembly 10 includes a transverse connecting plate 1001, and a strip through hole is provided on the side plate 9. The transverse connecting plate 1001 is slidably clamped in the strip through hole. A mounting fixing ring 1002 is fixedly installed on one end of the transverse connecting plate 1001.
