Power disks 14 are welded in the inserted cavities on both sides of the central axis 13. The power disks 14 are respectively sleeved with first arms 15 through connecting rods. The first arms 15 are connected with second arms 16 through pin shafts. An air collecting groove is provided at the upper end of the cavity.

Then the second piston 18 of the air intake valve moves downward along the guide rod 19.

Then the first piston 17 rises, and the second piston 18 rebounds to its original position to seal the air intake valve under the action of the second spring 20. Then the third piston 21 moves to one side of the inner cavity of the liquid collecting bag 1 through the sliding rod 22, and pushes the gas collected in the air collecting groove into the inner cavity of the liquid collecting bag 1 to pressurize the interior. Then, under the action of the third spring 23, a reciprocating operation is performed to pressurize the interior. Then, while clean water enters the inner cavity, the inner cavity is pressurized, the water valve of the lower liquid pipe 3 is opened, and the lower liquid pipe 3 is cleared. The operation is simple and easy to use. At the same time, the liquid in the inner cavity of the liquid collecting bag 1 must never exceed the pressurizing valve.
