The top side of the connecting ring 5 is fixedly connected to the motor 15 through a mounting plate. One end of the lead screw 14 extends to the top of the connecting ring 5 and is fixedly connected to the output end of the motor 15. The cleaning brush 8 is threadedly connected to the outside of the lead screw 14. The sealing plate 19 can be rotated through a linkage unit. The linkage unit includes a first gear 16.

[0023] Through the above technical solution, when it is necessary to arbitrarily control the water flow of the valve body 1, first loosen the bolt 12 to drive the rubber anti-slip pad away from the turntable 11, and then manually rotate the rotating column 10 to drive the rotating inner cylinder 3 to rotate, thereby adjusting the liquid outlet 4 exposed to the outside of the sealing block 2. The water flow of the valve body 1 can be correspondingly adjusted through the liquid outlet holes 4 with different apertures. When the valve body 1 needs to be closed, all the liquid outlet holes 4 are rotated to fit with the inner wall of the sealing block 2 to block the water flow, thereby achieving the purpose of closing the water flow. In daily use, Impurities in the water source are filtered through the filter 6. When there are too many impurities adhering to the filter 6 and it needs to be cleaned, the water flow is first turned off, and then the motor 15 is started by the external controller. The output end of the motor 15 drives the screw 14 to rotate, so that the screw 14 drives the cleaning brush 8 to move downward under the limit of the limit rod 7 through the threaded connection relationship, and the filter 6 can be cleaned. At the same time, the screw 14 rotates, and the first gear 16 at the bottom is driven to rotate.

After cleaning is completed, the motor 15 is reversed, and the sealing plate 19 can be driven to close and the cleaning brush 8 can be raised again through the reverse process operation. This operation can be repeated many times to achieve a thorough cleaning of the filter 6, thereby improving the water flow rate and avoiding the trouble of manually disassembling the valve body 1 to clean the filter 6, thereby greatly improving the cleaning efficiency and practicality of the device. The liquid hole 4 adjusts the water flow of the valve body 1 accordingly. When the valve body 1 needs to be closed, all the liquid outlet holes 4 are rotated to fit into the inner wall of the sealing block 2 to block the water flow, thereby achieving the purpose of arbitrarily controlling the water flow. In daily use, impurities in the water source can be filtered through the filter 6, and through simple operation, the cleaning brush 8 can be driven to automatically clean the filter 6 and collect impurities through the dust collection frame 18, avoiding the trouble of manually disassembling the valve body 1 and cleaning the filter 6, thereby greatly improving the cleaning efficiency and practicality of the device.

When the valve body 1 needs to be closed, all the liquid outlet holes 4 are rotated to fit with the inner wall of the sealing block 2 to block the water flow, thereby achieving the purpose of closing the water flow. In daily use, impurities in the water source can be filtered through the filter 6. When the impurities in the filter 6 are When there is a lot of impurities adhering to the filter screen and they need to be cleaned, the water flow is first turned off, and then the motor 15 is started through the external controller.
