[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Please refer to Figure 1-4A filter water treatment upper pipeline assembly includes: a pipe body 1, the pipe body 1 is U-shaped, a connecting pipe 2 is provided at the bottom of the pipe body 1, a pipe cover 3 is provided at the bottom end of the connecting pipe 2, a piston 4 is slidably installed in the pipe body 1, the piston 4 corresponds to the connecting pipe 2, and the piston 4 can slide down into the connecting pipe 2 to seal the connecting pipe 2. When in use, water flows in the pipe body 1, and impurities in the water are precipitated into the connecting pipe 2. When it is necessary to clean the impurities in the connecting pipe 2, the piston 4 is moved downward into the connecting pipe 2, so that the top of the connecting pipe 2 can be sealed, and then the pipe cover 3 is opened to clean the impurities, without stopping the machine, and does not affect the water treatment efficiency.

[0023] A housing 5 is provided above the middle of the tube body 1, and a driving unit is provided in the housing 5. The driving unit is used to drive the piston 4 to move up and down. The piston 4 extends upward into the housing 5, and the piston 4 is slidably and sealedly connected to the tube body 1. The piston 4 is provided with a relatively long length, and after it extends downward into the connecting pipe 2, the top end is still located in the housing 5, thereby preventing water from entering the housing 5 and affecting the operation of the driving unit or water leakage.

[0024] The driving part comprises a threaded sleeve 6 , which is rotatably mounted on the top of the housing 5 , and a screw rod 7 is threadedly connected inside the threaded sleeve 6 , and the screw rod 7 is fixedly connected to the piston 4 .

[0025] A limiting rod 61 is provided in the housing 5, and a limiting groove 71 is provided on the screw rod 7. The limiting rod 61 extends into the limiting groove 71 and is slidably connected to the inner wall of the limiting groove 71. The limiting rod 61 cooperates with the limiting groove 71 to prevent the screw rod 7 from rotating when the threaded sleeve 6 rotates, thereby preventing the screw rod 7 from being unable to move up and down.

[0026] The diameter of the piston 4 is smaller than the inner diameter of the connecting pipe 2. A sealing ring 41 is disposed on the outer sleeve of the piston 4. The sealing ring 41 is in an inverted cone shape and is elastic. When the piston 4 enters the connecting pipe 2, the sealing ring 41 contracts upward under the action of pressure, and the water in the connecting pipe 2 can be squeezed to the top of the sealing ring 41, thereby ensuring that the piston 4 enters the connecting pipe 2 normally; when the piston 4 stops moving, the sealing ring 41 expands downward under the action of the water pressure above the sealing ring 41, thereby sealing with the inner wall of the connecting pipe 2. At the same time, the diameter of the piston 4 is small, and it will not block the flow of water in the tube body 1 when cleaning impurities in the connecting pipe 2.

[0027] The middle upper wall of the tube body 1 is horizontal. When the piston 4 is located at the uppermost position, the sealing ring 41 is attached to the middle upper wall of the tube body 1 , which can further prevent water from leaking through the connection between the piston 4 and the tube body 1 .

[0028] A thread 21 is provided at the bottom of the connecting pipe 2 , and the pipe cover 3 and the connecting pipe 2 are screwed together via the thread 21 .

[0029] An annular groove 31 is formed on the inner wall of the bottom of the pipe cover 3 . A sealing gasket 32 ​​is embedded in the annular groove 31 . The sealing gasket 32 ​​protrudes upward from the annular groove 31 and abuts against the connecting pipe 2 .

[0030] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
