In this arrangement, the fixing ring 16 is used to prevent the collection pipe 17 from completely falling into the inside of the telescopic sleeve 18 .

As shown in Figures 1 to 4, further, the top ends of the inner wall of the filter cartridge 1 are fixedly connected with chute 14, and the chute 14 is provided with multiple stages, the same connecting plate 13 is slidably connected to the chute 14, and connected Both ends of the plate 13 and one side of the chute 14 are arc-shaped with the same center of the filter cartridge 1, and the bottom end of the middle part of the connecting plate 13 is fixedly connected with a plunger 15, and the plunger 15 is adapted to the diameter of the collecting pipe 17. In this setting, the degree of compression of the spring 20 is changed by adjusting the engagement of the connecting plate 13 and the chute 14 of different heights, so that the force used when the spring 20 is further compressed is different, and the diameter of the plunger 15 and the collection pipe 17 are compatible. Fitted to prevent the flow of water from entering the collection pipe 17 before reaching the proper depth.
