A pulley (16) is connected to the upper shaft of the generator (15). A belt groove (17) is provided on the outer wall of the ring (1001). A belt (18) for transmission is installed in both the pulley (16) and the belt groove (17). The generator (15) is connected to a storage battery module.

7. A flow-guiding filter according to claim 6, characterized in that: It also includes a controller, which is connected to the storage battery module and is connected to the first motor (13) and the second motor (1009) respectively.

8. A filtration method for a flow-directing filter, characterized in that, The flow-guiding filter according to any one of claims 1-5 includes the following steps: Step 1: Connect the inlet (3) to the water supply pipe and the outlet (5) to the outlet pipe; Step 2: Rotate the turntable (2) to connect the opening of the filter chamber (9) with the water inlet (3) and connect the water outlet (7) with the water outlet (5); Step 3: Water flows into the filter chamber (9) from the inlet (3). The filter cartridge (1003) intercepts impurities on its outside. The filtered water enters the interior of the filter cartridge (1003). Then the water flows from the ring (1001) to the fan-shaped cavity (6). The water flows through the outlet hole (7) and the outlet (5) in sequence, and then enters the outlet pipe. Step 4: When discharging slag, the turntable (2) rotates, connecting the connection port (8) with the water inlet port (3), and the opening of the filter chamber (9) is connected with the waste outlet (4). The bristles (1101) are pushed to contact the filter cylinder (1003) under the weight of the counterweight (1102). Step 5: Adjust several strip plates (1004) to tilt. Water flows into the fan-shaped cavity (6) from the inlet (3) and the connection port (8), and then enters the interior of the filter cylinder (1003) through the ring (1001). The water flow cooperates with several strip plates (1004) to drive the filter assembly (10) to rotate, and the filter cylinder (1003) rotates. Water flows through the filter cylinder (1003), and the water flow backwashes the outer wall of the filter cylinder (1003). The bristles (1101) brush off the impurities on the outer wall of the filter cylinder (1003), and the impurities are discharged from the waste outlet (4) with the water flow.
