[0031] By adopting the above technical scheme, first, after the medium enters the shell 1 through the water inlet end cover body 2, the first buffer plate 602 and the second buffer plate 603 embedded in the fixed shell 601 cooperate, the reserved holes formed in the first buffer plate 602 and the second buffer plate 603 are distributed in a staggered manner, which can effectively disperse and maintain the flow of the medium, reduce the impact force, avoid direct impact of the medium on the filter assembly 4, avoid excessive impact force so as to not fully and uniformly combine with the filter assembly 4, affect the filtering and purifying effect, and when the drive vane 607 is impacted by the medium, the rotating rod 605 is driven to rotate along the mounting hole 604 under the limitation of the limit ring 606, thereby dispersing the impact of the medium, avoiding excessive impact of the medium on the filter assembly 4 in the shell 1 to affect the service life, after the medium is filtered and purified by the filter assembly 4, the medium entering the filter assembly 4 is clean water, and the medium not entering is waste water, the clean water is discharged through the clean water pipe 5, the sleeving hole 10 and the water outlet pipe of the water outlet end cover body 3 and is used in the next process, and the waste water is discharged after being filtered again by the waste water filter plate 8 embedded in the fixed frame 7, and the filter assembly 4 is limited by the limiting hole 9.

[0032] Specifically, as Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the lower part of the rotating rod 605 is provided with a cleaning mechanism 11, which includes a connecting plate 1101 fixedly installed on the outer wall of one end of the rotating rod 605 passing through the bottom end of the second buffer plate 603, one end of the connecting plate 1101 is fixedly installed with a mounting plate 1102, the mounting plate 1102 is embedded with a cleaning soft brush 1103 facing the outer wall of the filter assembly 4, the bottom end of the rotating rod 605 is fixedly installed with a limiting rod 1104, and the top end of the filter assembly 4 is provided with a bearing hole 1105 corresponding to the position of the limiting rod 1104.

[0033] By adopting the above technical scheme, first, when the rotating rod 605 rotates, the connecting plate 1101 is driven to rotate, thereby driving the mounting plate 1102 to rotate, and the cleaning soft brush 1103 is attached to the outside of the filter assembly 4 to rotate, which can scrape off the dust and impurities adsorbed on the outermost layer of the filter assembly 4, avoid the situation that the adsorption is excessive and forms a blockage, thereby affecting the filtering effect, and at the same time, the limiting rod 1104 at the bottom end of the rotating rod 605 penetrates into the bearing hole 1105 provided in the filter assembly 4, so that the rotating rod 605 can rotate stably.

[0034] Working principle: the filter assembly 4 is composed of multiple filter layers such as anti-pollution coating, non-woven fabric reinforcing layer, dense skin layer and bonding layer, which is a conventional and existing technology and will not be described here.
