The first filter disc 20 is provided with a second leak, and the second leak corresponds to the discharge port at the bottom of the outer box 1, so that the retainer can be discharged through the second leak and the discharge port under the drive of the scraper 22.

[0025] The annular stand 13 is also provided with two notches, one of which is adjacent to the first funnel, and the two notches are respectively opposite to the head and tail ends of the ring 403, so that when the support frame 4 is extended and retracted relying on the ring 403, the second cleaning brush 7 will not be restricted by the annular stand 13 when it is flipped at the head and tail ends of the ring 403.

[0026] The implementation principle of a ball cage holder cleaning device in the embodiment of the present application is: During deployment, the annular spray pipe 23 is connected to an external water pipe to spray the cleaning liquid, and then the drainage port at the bottom of the outer box 1 is connected to an external sewage pipe to discharge sewage; When cleaning the retainer (ball cage retainer), the retainer can be put in from the inlet at the top of the outer box 1, and the retainer falls onto the annular stand 13 and is located at the corresponding support 4. Then the first motor 2 drives the rotating wheel 3 to rotate (the rotating wheel 3 rotates and the rotating ring 21 is driven to rotate synchronously), and the rotating wheel 3 drives the multiple support 4 and the retainer located at the support 4 to rotate. When the guide wheel 402 on the support 4 moves to the support ring 403, the support 4 moves and squeezes the spring 5, and pushes the retainer against the annular stand 13, so that the spherical brush 16 on the annular stand 13 can extend into the window of the annular stand, and the first cleaning brush 6 contacts the outer wall of the retainer; At the same time, the support frame 4 will also drive the large gear 9 and the second cleaning brush 7 to move when it moves. The large gear 9 will drive the second cleaning brush 7 to rotate through the small gear 8 under the action of the long rack 10, so that the second cleaning brush 7 flips up and down and contacts the inner wall of the holder, so that the holder can roll around the annular stand 13. When it rolls, the multiple spherical brushes 16 can sequentially clean the multiple windows thereon, while the first cleaning brush 6 and the second cleaning brush 7 clean the outer wall and the inner wall thereof respectively, until the support frame 4 drives the holder to transfer to the first leakage port, at which time the guide wheel 402 on the support frame 4 is detached from the support ring 403, the support frame 4 and the second cleaning brush 7 are reset, and the cleaning completed holder falls from the first leakage port onto the filter disc 20, and is transferred to the second leakage port driven by the scraper 22 and falls, and is discharged through the discharge port; When cleaning the window of the retaining frame, the second motor 12 rotates back and forth through the turntable 14, so that the multiple telescopic rods 15 can drive the multiple spherical brushes 16 to swing left and right, and under the action of the gear ring 18 and the annular rack 19, the spherical brush 16 can not only swing left and right, but also rotate to a certain extent while swinging, thereby improving the cleaning effect of the retaining frame window.
