The bottom of the filter screen 6 is inserted into the top of the support base 7. Water flows through the filter holes of the filter screen 6 and enters the housing 1. Impurities are filtered and trapped in the filter screen 6, thereby filtration and purification of the water flow. The top of the connector 2 is fixed with a motor 3 by bolts. The output end of the motor 3 is fixed with a connecting frame 4 by bolts. A cleaning brush 5 is fixed with bolts on one side of the connecting frame 4. The cleaning brush 5 contacts the inner wall of the filter screen cylinder 6. The bristles of the cleaning brush 5 are soft nylon bristles and can enter the aperture of the filter screen cylinder 6. Driven by the motor 3, the connecting frame 4 rotates, thereby driving the cleaning brush 5 to brush the inner surface of the filter screen cylinder 6, thereby brushing off the impurities adhering to the inner surface of the filter screen cylinder 6. The outer side of the housing 1 is provided with a first sewage discharge component 8 and a second sewage discharge component 9.

The other end of the connecting pipe 801 is connected to a first water inlet electric valve 802 through a flange. Water flows into the connecting pipe 801 from the first water inlet electric valve 802. Then, the water flows from the connecting pipe 801 to the outer surface of the filter screen cylinder 6, thereby rinsing the outer surface of the filter screen cylinder 6.

[0020] The bottom of the housing 1 is connected to a third tee pipe 17 via a flange. The bottom end of the third tee pipe 17 is connected to a first drain electric valve 804 via a flange. The bottom end of the first drain electric valve 804 is connected to a first drain pipe 803 via a flange.

[0021] One end of the third three-way pipe 17 is connected to the outlet electric valve 12 via a flange, and the other end of the outlet electric valve 12 is connected to the outlet pipe 13 via a flange. The purified water flows into the third three-way pipe 17 and is then discharged from the outlet electric valve 12 and the outlet pipe 13 for use.

[0022] The second sewage discharge assembly 9 includes a second inlet electric valve 901, which is connected to the inlet end of the connector 2 via a flange. Water flows from the second inlet electric valve 901 into the filter screen cylinder 6, thereby rinsing the inner surface of the filter screen cylinder 6.

[0023] A fixed pipe 902 is sealed and inserted into the bottom of the support base 7. The other end of the fixed pipe 902 passes through the housing 1 and is connected to a second sewage discharge electric valve 903 via a flange. The other end of the second sewage discharge electric valve 903 is connected to a second sewage discharge pipe 904 via a flange.

The other ends of the two one-way valves 14 are connected to the same second three-way pipe 15 via flanges. The bottom end of the second three-way pipe 15 is connected to a sludge discharge pipe 16 via a flange. Sewage and impurities inside and outside the filter screen cylinder 6 are discharged from the first sewage discharge pipe 803 and the second sewage discharge pipe 904 respectively, and then discharged from the one-way valve 14, the second three-way pipe 15, and the sludge discharge pipe 16.

[0024] The other end of the second inlet electric valve 901 is connected to the first tee pipe 10 via a flange. One end of the first tee pipe 10 is connected to one end of the first inlet electric valve 802 via a flange. The other end of the first tee pipe 10 is connected to the inlet pipe 11 via a flange.

[0025] The working principle of this embodiment is as follows: When in use, the second inlet electric valve 901 and the outlet electric valve 12 are opened. Water flows from the inlet pipe 11, the first three-way pipe 10 and the second inlet electric valve 901 into the filter screen cylinder 6. Then, the water flows through the filter holes of the filter screen cylinder 6 into the housing 1. Impurities are filtered and trapped in the filter screen cylinder 6, thereby filtration and purification of the water. Then, the purified water flows into the third three-way pipe 17 and is discharged from the outlet electric valve 12 and the outlet pipe 13 for use. During cleaning, the motor 3 is started, and the connecting frame 4 rotates under the drive of the motor 3, thereby driving the cleaning brush 5 to brush the inner surface of the filter screen cylinder 6, thereby brushing off the impurities adhering to the inner surface of the filter screen cylinder 6, and then the impurities fall onto the support base 7. At the same time, the outlet electric valve 12 is closed, and the first inlet electric valve 802, the first drain electric valve 804, and the second inlet electric valve 901 are opened. Water flows from the inlet pipe 11, the first three-way pipe 10, and the second inlet electric valve 901 into the filter screen cylinder 6, thereby rinsing the inner surface of the filter screen cylinder 6. At the same time, water flows into the connecting pipe 801 from the inlet pipe 11, the first three-way pipe 10 and the first inlet electric valve 802. Then, the water flows from the connecting pipe 801 to the outer surface of the filter screen cylinder 6, thereby rinsing the outer surface of the filter screen cylinder 6. The sewage and impurities inside the filter screen cylinder 6 flow into the fixed pipe 902, and then are discharged through the second sewage discharge electric valve 903, the second sewage discharge pipe 904, the one-way valve 14, the second three-way pipe 15 and the sludge discharge pipe 16. Sewage and impurities located on the outside of the filter screen cylinder 6 inside the shell 1 flow into the third three-way pipe 17, and then are discharged through the first sewage discharge electric valve 804, the first sewage discharge pipe 803, the one-way valve 14, the second three-way pipe 15, and the sludge discharge pipe 16, thereby quickly discharging impurities and sewage.
