[0019] The motor drives the disc to rotate, and the disc constantly contacts the inner walls on both sides of the connection frame, pushing the connection frame, the primary filter tank and the secondary filter tank to move back and forth, so that the impurities are concentrated at the lowest point of the filter layer, the water is discharged through the filter layer, and the jig remains on the filter net, completing the separation of the jig and the water;

[0020] In summary, the present invention realizes the self-sensing function by setting a proximity sensor and setting a plurality of cleaning tanks, thereby realizing the continuous discharge, cleaning and discharging operations, facilitating the replacement of cleaning jigs, and simultaneously realizing the reciprocating movement of the movable frame and the primary filter tank and the secondary filter tank through the drive of the motor, thereby speeding up the cleaning process and the separation of the jig from the water body.

[0031] A slide groove is provided on the outer wall of the support plate 1, and a slide plate is slidably provided in the slide groove. The outer wall of the slide plate is fixedly connected with a primary filter groove 24, and a secondary filter groove 26 is fixedly provided on the lower side wall of the primary filter groove 24. A filter screen 25 is fixed in the primary filter groove 24, and a filter element layer 27 arranged obliquely is fixed in the secondary filter groove 26. A sewage discharge groove located at the lowest point of the filter element layer 27 is provided on the outer wall of the secondary filter groove 26, and a movable plate 28 is rotatably connected to the outer wall of the secondary filter groove 26, and a rubber plug matching the sewage discharge groove is fixed on the outer wall of the movable plate 28. After the cleaning of the fixture is completed, the rotation of the turntable 3 drives the cleaning groove 4 on the far right to rotate downward. At this time, the fixture that has been cleaned in the cleaning groove 4 slides out and falls into the primary filter groove 24. The mesh of the filter screen 25 is larger, and the water body and impurities are led out to the secondary filter groove 26, and the fixture remains in the primary filter groove 24. The cleaning groove 4 from which the fixture is led out subsequently rotates to the uppermost side as the turntable 3 rotates, and then the fixture to be cleaned is put in to continue the cleaning work.

[0032] The outer wall of the primary filter tank 24 is fixedly connected with a connecting frame 29, a motor 16 is fixed to the rear side wall of the support plate 1, a driving end of the motor 16 passes through the support plate 1 and is fixedly connected with a disc 18 located in the connecting frame 29, a connection between the driving end of the motor 16 and the disc 18 is set away from the center of the disc 18, a pulley 17 is fixedly sleeved on the outer wall of the driving end of the motor 16, a bearing is fixedly fixed to the outer wall of the support plate 1, a rotating shaft is fixedly provided on the inner ring of the bearing, a pulley 2 19 is fixedly sleeved on the outer wall of the rotating shaft, a belt 20 is jointly sleeved on the outer walls of the pulley 1 17 and the pulley 2 19, a rotating plate 21 is fixedly connected to the end of the rotating shaft, a push plate 22 is fixedly connected to the outer wall of the rotating plate 21, an arc block is fixedly provided on the end of the push plate 22, a connecting block 8 is fixedly connected to the outer wall of the cleaning tank 4, an end of the connecting block 8 passes through and extends to the outside of the turntable 3, the turntable A through groove 9 is provided at the connection between the rotating disk 3 and the connecting block 8. The cleaning tank 4 with the jig is rotated to the right with the rotation of the rotating disk 3. At this time, the connecting block 8 on the right is located on the left side of the arc block. The motor 16 is started to drive the disc 18 to rotate. Through the transmission effect of the belt 20, the pulley 19, the rotating plate 21 and the push plate 22 are driven to rotate. The arc block is constantly in contact with the connecting block 8 during the rotation. When the arc block contacts the connecting block 8, the connecting block 8 and the movable net frame 6 are first pushed to move to the bottom of the cleaning tank 4, and the reset spring 7 is squeezed to make it shrink. When the arc block rotates away from the connecting block 8, the movable net frame 6 bounces up under the reverse elastic force of the reset spring 7, and then the reciprocating movement of the movable net frame 6 is realized through the rotation of the arc block, so that the internal jig is fully shaken and contacts the brush roller 15, thereby brushing away the impurities on the surface of the jig;

[0033] While the movable net frame 6 on the right side moves back and forth, the motor 16 drives the disc 18 to rotate. Since the driving end of the motor 16 is set away from the center of the disc 18, the disc 18 has a larger range of rotation. When the disc 18 rotates to the left, it will contact the left inner wall of the connecting frame 29, pushing the connecting frame 29 and the primary filter tank 24 to move to the left. When the disc 18 rotates to the right, it will contact the right inner wall of the connecting frame 29, pushing the connecting frame 29 and the primary filter tank 24 to move to the right, realizing the back and forth movement of the primary filter tank 24 and the secondary filter tank 26, so that impurities are concentrated at the lowest point of the filter element layer 27, and the water is discharged through the filter element layer 27. The jig remains on the filter net 25, and the movable plate 28 is subsequently rotated outward to separate the rubber plug from the sewage tank, so that the impurities can be discharged from the secondary filter tank 26.

[0034] Furthermore, the end of the movable panel 28 can be fixedly mounted on the outer wall of the secondary filter tank 26 by bolts or the like, so as to facilitate the opening of the movable panel 28 .

[0035] In summary, the cleaning of the fixture includes the following steps:

[0036] Put the jig into the movable net frame 6, and the motor 2 drives the turntable 3 to rotate, so that the cleaning tank 4 with the jig is turned to the right, so that the next cleaning tank 4 is located at the uppermost side. At this time, the through port is connected with the water inlet 11 located in the middle, and the proximity sensor 23 senses that the jig has come to the right position, and starts the motor 16 and the high-pressure liquid pump 12 to perform cleaning work.

[0037] The high-pressure liquid pump 12 pumps the external water into the water inlet 11, and then sprays it out from the nozzle 10 to contact the fixture. The motor 16 drives the disc 18 to rotate, and through the transmission action of the belt 20, drives the pulley 19, the rotating plate 21 and the push plate 22 to rotate. The arc block constantly contacts with the connecting block 8 during the rotation process, squeezes the connecting block 8 to move, or moves away from the connecting block 8 to reset the movable net frame 6 under the elastic force of the reset spring 7, and then the reciprocating movement of the movable net frame 6 is realized through the rotation of the arc block, so that the internal fixture is fully shaken and contacts the brush roller 15, and the impurities on the surface of the fixture are brushed off in combination with the flushing of the water flow;

[0038] After the cleaning is completed, the motor 2 continues to drive the turntable 3 to rotate the cleaning tank 4 that has completed the cleaning to the lower side, so that the cleaned fixture is led out. After that, the motor 2 continues to drive the turntable 3 to rotate, so that the cleaning tank 4 that has led out the fixture is rotated to the upper side, and the fixture to be cleaned is continued to be put in for cleaning, so as to realize continuous cleaning;

[0039] During the cleaning process of the fixture, the motor 16 drives the disc 18 to rotate. When the disc 18 rotates to the left, it will contact the left inner wall of the connecting frame 29, pushing the connecting frame 29 and the primary filter tank 24 to move to the left. When the disc 18 rotates to the right, it will contact the right inner wall of the connecting frame 29, pushing the connecting frame 29 and the primary filter tank 24 to move to the right, thereby realizing the back and forth movement of the primary filter tank 24 and the secondary filter tank 26, so that the internal water body can be quickly filtered and discharged through the filter element layer 27, and can then be pumped back to the nozzle 10 by the high-pressure liquid pump 12 for reciprocating use.
