[0023] In this embodiment, the telescopic tube 8 is located in the storage groove 7 and is arranged to match each other. The front and rear parts of the telescopic tube 8 are respectively connected to the inside of the intake pipe 5 and the fixed ring 10. The telescopic tube 8 can be extended to facilitate the extension of the length of the intake pipe 5 and the adjustment of the intake position.

[0024] In this embodiment, the first screw groove 13 and the first screw ring 9 are threadedly connected, and the positioning sleeve 11 is located on the periphery of the fixing ring 10 and is movably rotatable. The positioning sleeve 11 is fixed by the connection between the first screw groove 13 and the first screw ring 9, which is convenient for installation and telescopic adjustment.

[0025] In this embodiment, a plurality of positioning blocks 14 and a plurality of positioning grooves 15 are arranged in a ring shape, and the positioning blocks 14 and the positioning grooves 15 are snap-connected. The positioning blocks 14 are snapped into the positioning grooves 15 to fix the fixing ring 10, thereby preventing the fixing ring 10 from rotating with the positioning sleeve 11 and causing damage to the telescopic tube 8.

[0026] In this embodiment, the sealing assembly 4 includes a sealing sleeve 16, which is connected and installed on the front part of the positioning sleeve 11. A filter screen 18 is fixedly installed inside the sealing sleeve 16. A second screw ring 17 is opened on the outer ring of the sealing sleeve 16 near the rear end. A screw 19 is movably installed at the center position of the inner part of the filter screen 18. A sealing disk 20 is fixedly installed on the front end of the screw 19.
