step two, in the cleaning process, the whole device is vertically placed, the clean water inlet (26) faces the upper end, the second sealing cover (12) drives the sealing filling block (14) to rotate, the limitation on the connecting clamping groove (11) is lost after the sealing filling block rotates, the first sealing cover (10) rotates by taking the rotating rod (15) as the circle center while limiting, and the clean water inlet (26), the connecting rod (6) and the rotating handle (7) can be exposed;
conveying the cleaned liquid into the device through a clean water inlet (26), wherein in the conveying process, a rotating handle (7) drives a sealing sliding block (4) to rotate through a connecting rod (6), in the rotating process of the sealing sliding block (4), a second cleaning brush (30) can be driven to rotate through a cleaning plate (5), the rotation of the second cleaning brush (30) and an ultrafiltration membrane wire (17) can generate friction and extrusion, and the extrusion and friction are matched with cleaning liquid for cleaning;
and step four, the cleaning plate (5) rotates, and meanwhile, the third supporting rod (28) and the first cleaning brush (29) outside the second supporting rod (27) are matched with the second cleaning brush (30), and the matching can rub and extrude the inside of the ultrafiltration membrane wire (17), so that the inside is cleaned.
