The scraping and washing frames 15 are connected by a plurality of reinforcing rings 34 which are uniformly distributed in the longitudinal direction.

The utility model discloses a use method as follows:

firstly, the water inlet joint 4 is connected with a water pipe for water inlet, the water outlet joint 5 is connected with a flow direction terminal pipeline, when water flow in the water pipe flows through the water inlet joint 4, the water flow enters the filter cylinder 8 through the water passing head 7, then flows into the shell 1 through the net port 9 on the filter cylinder 8, at the moment, the net port 9 has a filtering effect, impurities in the water flow are blocked in the filter cylinder 8, the water flow flowing out of the filter cylinder 8 is clean water flow, the water flow flows into the shell 1 along with the continuous flow of the subsequent water flow and flows out of the filter cylinder 8, the shell 1 is filled with the water flow, at the moment, under the action of the subsequent water flow, the water pressure rises, the water flow surges upwards and flows into the fixed sleeve 17 through a gap between the scraping and washing frames 15, and because the front side and the rear side of the water outlet groove 18 are provided with the water discharging holes 23 communicated with the inner space of the fixed sleeve 17, the water flow entering the fixed sleeve 17 can enter the water outlet groove 18 through the water discharging holes 23 and are separated by the left baffle plate 19 and the right baffle plate 19 In each space, the water flow in the two spaces enters the water storage cavity 21 through the water outlet 22, and the water in the water storage cavity 21 is discharged to the pipeline connected with the water outlet joint 5 through the right water outlet 22, the water outlet channel 14 and the water outlet joint 5 in sequence, and finally the clean water flow is output from the terminal for use.

When water flow enters the fixed sleeve 17, the water flow in the fixed sleeve 17 is divided into two flows along with the water flow flowing to the water discharge holes 23 on the front side and the rear side respectively, the two flows flowing at this moment form a vortex flowing orderly in the fixed sleeve 17, a water guide inclined plane 24 is arranged on the hole wall on one side of the water discharge hole 23, the water guide inclined planes 24 of the water discharge holes 23 on the front side and the rear side rotate clockwise, the vortex can be ensured to flow towards one direction all the time under the guidance of the water guide inclined plane 24 to the maximum extent, after the vortex flowing towards one direction all the time is formed in the fixed sleeve 17, the vortex pushes the rotating blade 13 through the pressure generated by the self-flowing, so that the rotating blade 13 drives the rotating sleeve 10 to rotate towards one direction, when the rotating sleeve 10 rotates, the rotating sleeve 10 drives the scraping frame to rotate, along with the rotation of the scraping frame 15, the scraping frame 15 drives the water flow in the shell 1 to flow, form a stable swirl in casing 1 once more, and scrape and wash frame 15 and enclose cartridge filter 8 including closing, consequently cartridge filter 8 just is in the center of the swirl in casing 1, consequently rivers in the swirl then can have one all the time and do all the time power to strike towards cartridge filter 8 inside through net gape 9, when impurity tries to adhere in net gape 9, impurity then can be directly washed back to cartridge filter 8 in by the rivers of swirl, even there is the impurity adhesion at net gape 9 port position, scrape washing piece 16 also can be along with scrape washing frame 15 rotatory with the adhesion in net gape 9 is scraped to the net gape in with the impurity of net gape port position, impurity in net gape 9 is the same can the number of the dead by the rivers of swirl rush into cartridge filter 8 at this moment, guarantee net gape 9 all the time can not have the impurity adhesion, guarantee net gape 9's clean degree.

In conclusion, the present invention can filter the water flow and simultaneously utilize the flowing water flow to form a vortex in the fixed sleeve 17, the vortex in the fixed sleeve 17 will drive the rotary sleeve 10 to rotate, thereby driving the scraping and washing frame 15 to rotate, along with the rotation of the scraping and washing frame 15, the scraping and washing frame 15 can drive the water flow in the shell 1 to flow and form a vortex in the shell 1, the water flow of the vortex in the shell 1 can flush the impurities adhered to the mesh into the filter cylinder 8 to retain the impurities in the filter cylinder 8, and can keep the clean degree of net gape 9 constantly, realize the effect of washing certainly, need not to take out cartridge filter 8 from leading filter, just can effectively wash cartridge filter 8, reduced work load and trouble, and cleaning work goes on in step with filtering work, can guarantee the cleaning efficiency in the at utmost.

If feel when tentatively rinsing the cartridge filter and have impurity to remain outside cartridge filter 8, then valve 33 is opened to accessible hand wheel 3301, rivers in the casing 1 no longer upwards flow this moment, but the downflow, rivers at first then can be through the clearance flow direction delivery hole 30 between connector 28 outer wall and the casing 1 lower extreme inner wall, then enter into water delivery hole 29 through delivery hole 30, rivers loop through connecting pipe 27 immediately, valve 33, the discharge of valve hole 32 lower extreme orifice, thereby discharge the dirty water in the casing 1, guarantee that casing 1 inside can keep clean state, there is not impurity to remain.

The scraping and washing frames 15 are connected through a plurality of reinforcing rings 34 which are uniformly distributed in the longitudinal direction, and the existence of the reinforcing rings 34 can effectively improve the strength of the scraping and washing frames 15.
