[0027] Furthermore, a second filter plate 13 is slidably connected to the inner wall of the collecting frame 9, and rotating shafts 14 are fixedly connected on both sides of the second filter plate 13. The two rotating shafts 14 are slidably connected to the inside of the collecting frame 9, and two moving blocks 16 are slidably connected to both sides of the inside of the collecting frame 9. The ends of the two rotating shafts 14 away from the second filter plate 13 are respectively connected to the inside of the two moving blocks 16 for rotation.

[0032] Working principle: when draining water, the micro motor 8 is started to drive the push plate 11 to rotate on the surface of the first filter plate 10, so as to push the blockage retained on the first filter plate 10, so as to push the blockage into the collection frame 9 with the rotation of the micro motor 8, and at the same time, under the impulse of the water flow in the base 1, the blockage is gathered in the storage tube 4, and then with the rotation of the push plate 11, the inclined surface of the squeezing block 20 contacts the lifting frame 12, so that the inclined surface of the squeezing block 20 squeezes the lifting frame 12, and then drives the lifting frame 12 to slide in the collection frame 9, thereby driving the two rotating shafts 14 to slide in the collection frame 9, so that the gear 15 is engaged with the tooth plate 18, so that the rotating shaft 14 is in the collection frame 9 It rotates while sliding, so that the second filter plate 13 changes from a vertical state to a horizontal state, thereby closing the collection frame 9. At the same time, the rotating shaft 14 drives the moving block 16 to slide in the collection frame 9 and compresses the spring 17. Due to the continuous squeezing of the inclined surface of the squeezing block 20, the lifting frame 12 continues to slide. At this time, due to the large friction between the moving block 16 and the rotating shaft 14, the second filter plate 13 remains horizontal and continues to descend, so that the blockage in the collection frame 9 can be pushed, and when there are more blockages in the storage tube 4, the blockage in the storage tube 4 can be squeezed and compressed, and the moisture is discharged along the holes on the storage tube 4, so that more blockages can be stored in the storage tube 4, thereby improving the overall working time of the device.
