[0015] The specific implementation of the utility model will be further described in combination with the drawings and examples.

[0016] As Figs. 1-2As shown, a sleeve type multi-nozzle adjusting valve with filtering function comprises a valve body 1, a water inlet channel 2 and a water outlet channel opened on the valve body 1, and a filter screen 3, the filter screen 3 is arranged in the water inlet channel 2, a fixed plate 5 is arranged in front of the filter screen 3 in the water inlet channel 2, a sliding channel is opened in the lower end of the fixed plate 5 and one end of the sliding channel penetrates through the fixed plate 5, a sliding rod 6 is slidably arranged in the sliding channel, a limiting device for preventing the sliding rod 6 from sliding out of the sliding channel is arranged on the fixed plate 5, a brush 4 is rotatably arranged on one end of the sliding rod 6 through a rotating motor, the rotating motor is arranged in the sliding rod 6, the rotating shaft of the rotating motor is threadedly connected to the brush rod of the brush 4, the other end of the sliding rod 6 is provided with a pushing device for intermittently pushing the brush 4 against the filter screen 3, a cleaning channel is opened in front of the filter screen 3 on the valve body 1, and a sealing cover 10 is arranged in the cleaning channel.

[0017] Specifically, the limiting device comprises a limiting rod 11, a fixed sleeve 12 is arranged on the fixed plate 5, the limiting rod 11 penetrates through the fixed sleeve 12, one end of the limiting rod 11 supports the sliding rod 6 through the sliding channel, the other end of the limiting rod 11 penetrates out of the fixed sleeve 12, a fixed block 14 is slidably arranged in the fixed sleeve 12, the limiting rod 11 is arranged on the fixed block 14, an abutting spring 13 for abutting the limiting rod 11 against the fixed plate 5 is arranged in the fixed sleeve 12, the abutting spring 13 is sleeved on the limiting rod 11, one end of the abutting spring 13 is in abutment with the fixed block 14, and the other end of the abutting spring 13 is in abutment with the inner wall of the fixed sleeve 12.

[0018] Specifically, the pushing device comprises an eccentric wheel 9, the eccentric wheel 9 is rotatably arranged in the water inlet channel 2 through a rotating shaft, a pushing plate 8 is arranged on the sliding rod 6, the eccentric wheel 9 is in abutment with the pushing plate 8, a return spring 7 is sleeved on the sliding rod 6, one end of the return spring 7 is in abutment with the fixed plate 5, and the other end of the return spring 7 is in abutment with the pushing plate 8, a driving motor for driving the rotating shaft to rotate is arranged on the valve body 1.

[0019] In order to facilitate pulling the limiting rod 11, a pulling plate is arranged on the limiting rod 11.

[0020] Working principle:

[0021] When in use, water flows through the water inlet channel 2, and passes through the filter screen 3, which filters the impurities in the water flow, thereby avoiding the impurities from entering the inside of the valve body 1, avoiding the impurities from corroding the inside of the valve body, and avoiding the inside of the valve body from being blocked. At the same time, the impurities will not be attached to the sealing pair to wear the sealing structure, thereby being beneficial to prolong the service life of the valve and being beneficial to the long-term use of the valve. When the filter screen 3 is filtering, the driving motor rotates to drive the eccentric wheel 9 to rotate, the eccentric wheel 9 pushes the sliding rod 6 to slide back and forth, so that the brush 4 intermittently abuts against the filter screen 3, then the motor rotates to drive the brush 4 to rotate, so that the brush 4 intermittently brushes the filter screen 3, thereby not only being beneficial to prolong the endurance of the filter screen 3, but also being beneficial to avoid the brush 4 from being attached to the filter screen 3 to affect the flow. Then, the sealing cover 10 is opened, and the impurities can be cleaned out. At the same time, when the brush 4 is damaged, the sealing cover 10 is opened, then the limiting rod 11 is pulled, the sliding rod 6 directly slides out of the sliding channel, and then falls out of the cleaning channel, so that the staff can replace the brush 4, which is simple and convenient, and is beneficial to the operation of the staff.
