[0030] The working principle of the utility model is as follows:

[0031] First, bring the connecting seat 1 into contact with the water inlet of the water pump. The fastening screw 21 is set on the threaded cylinder 22 in a threaded connection manner. The threaded cylinder 22 rotates on the connecting seat 1. The movable cylinder 23 also rotates on the connecting seat 1, and the annular gear 29 fixed on the movable cylinder 23 meshes with the auxiliary gear 210 fixed on the threaded cylinder 22. The sliding seat 26 slides on the connecting seat 1 and is further connected to the connecting seat 1 by using the return spring 27. The knob 24 rotates on the sliding seat 26, and the plug 28 fixed on the knob 24 is inserted into the connecting seat 1. Both ends of the connecting rod 25 are movably connected to the knob 24 and the movable cylinder 23 respectively. Therefore, pulling the knob 24 to make the plug 28 disengage from the connecting seat 1 allows the knob 24 to be rotated. Under the connection of the connecting rod 25, the movable cylinder 23 rotates synchronously. Also, under the transmission of the movable cylinder 23, the annular gear 29 and the auxiliary gear 210, the threaded cylinder 22 rotates, and the fastening screw 21 screws out from the inside of the threaded cylinder 22 and is connected to the water pump through the threads on the surface of the threaded cylinder 22. After loosening the knob 24, under the action of the return spring 27, the plug 28 is inserted into the inside of the connecting seat 1 again to restrict the rotation of the knob 24, thereby locking the overall structure.

[0032] The bracket 31 and the base 32 are both fixed on the connecting seat 1. The filter plate 35 is initially located inside the connecting seat 1 to filter impurities in the water. The two semi-circular filter plates 35 slide on the bracket 31 and the base 32 through the T-shaped rods 34 fixedly connected thereto. The lead screw 36 rotating on the base 32 is also threadedly connected to the T-shaped rod 34. The two threads with opposite helical directions on the lead screw 36 are respectively threadedly connected to the two T-shaped rods 34. Therefore, after rotating the lead screw 36, the two filter plates 35 perform mirror-image sliding and thus slide out from inside the connecting seat 1 to facilitate the user to clean them. After reversing the lead screw 36, the filter plates 35 will slide into the inside of the connecting seat 1 for filtering.
