Further, the scraping plate 21 is fixedly connected to the circumference of the impeller 2, and the scraping plate 21 is in clearance fit with the separating cylinder 1 and the tubular membrane 3 respectively, so that the rotating impeller 2 can drive the scraping plate 21 to rotate, and then the inner wall of the separating cylinder 1 and the side wall of the tubular membrane 3 are scraped, and the phenomenon that the tubular membrane 3 has a reduced water filtering effect due to the fact that more dirt is attached to the side wall of the tubular membrane 3 is avoided.

Further, the lower surface of the top sealing plate 14 is provided with a positioning column 141.

Further, the top sealing plate 14 is fixedly inserted with a water outlet pipe 15, and the water outlet pipe 15 penetrates through the top cover 11, and it should be noted that only axial displacement can occur between the water outlet pipe 15 and the top cover 11.

The water outlet pipe 15 and the central pipe 31 are connected in a sealing manner.

Further, the water outlet pipe 15 is sleeved with the spring 16 at the position between the top sealing plate 14 and the top cover 11, so that the existence of the spring 16 can enable the top sealing plate 14 to be in abutting connection with the tubular membrane 3, and it is noted that the elastic force of the spring 16 is larger than the water pressure in the separating cylinder 1, so that the top sealing plate 14 cannot be upwardly displaced under the action of the water pressure, and further, the water outlet pipe 15 and the central pipe 31 can be kept in sealing connection in the normal use process.
