[0033] Insert the connector 18 into one end of the coil pipe, and then also insert the head at the right end of the return water pipe 21 into the other end of the coil pipe. By pulling up the handle 8, the piston 7 can slide upward. At this time, the cleaning agent inside the liquid tank 1 can be drawn into the outer cylinder 5. By pressing down the handle 8, the piston 7 can move downward. At this time, the cleaning liquid inside the outer cylinder 5 can be sent into the coil pipe through the water outlet pipe 16. By repeating the operation, the cleaning liquid can pass through the coil pipe and then return to the liquid tank 1 through the return water pipe 21. When the cleaning liquid passes through the coil pipe, it can clean the inner wall of the coil pipe. By quickly moving the piston 7 downward, the cleaning liquid can have a greater impact force, so that the cleaning effect can be better. Through this mechanism, the cleaning effect can be better and it can be recycled, which is relatively resource-saving. The first filter screen 23 and the second filter screen 24 can filter the impurities in the cleaning liquid.
