A telescopic connecting component is provided between the water inlet pipe 4 and the water outlet pipe 5, so that the connecting ends of the connecting component are moved out from the inside of the water inlet pipe 4 or the water outlet pipe 5. The connecting component includes two connecting pipes 6. A rubber hose 7 is fixedly connected between the two connecting pipes 6. The outer diameters of the connecting pipes 6 are respectively adapted to the outer diameters of the water inlet pipe 4 and the water outlet pipe 5. Flanges 3 are fixedly sleeved on the surfaces of the connecting pipes 6, the water inlet pipe 4 and the water outlet pipe 5. Adjacent two flanges 3 are connected by connecting bolts 8.

[0019] In this embodiment, by providing a telescopic connection component, when it is necessary to disassemble the water inlet pipe 4 and the water outlet pipe 5, it is only necessary to unscrew the connection bolts 8 and then pull out the two sets of connecting pipes 6 from the water inlet pipe 4 and the water outlet pipe 5. The rubber hose 7 between the two sets of connecting pipes 6 can be telescoped to provide moving space for the disassembly of the connecting pipe 6, the water inlet pipe 4 and the water outlet pipe 5, thereby realizing the disassembly of the water inlet pipe 4 and the water outlet pipe 5.

The telescopic outer cylinder 1 is hollow, and one end of the telescopic outer cylinder 1 is fixedly connected to the connecting pipe 6. One end of the telescopic inner cylinder 2 is inserted inside the telescopic outer cylinder 1, and the other end of the telescopic inner cylinder 2 is fixedly connected to the connecting pipe 6.

[0021] In this embodiment, by providing the telescopic outer cylinder 1 and the telescopic inner cylinder 2 to cover the outer surface of the rubber hose 7, the rubber hose 7 can be protected from damage.
