Abstract
The utility model relates to a water-dredging device convenient for dredging a drainpipe and consists of a shell body. The shell body is divided into a plenum chamber, a pressure-releasing chamber and an air-storing chamber. The plenum chamber is provided with a manually-operated air-charging device. The air-storing chamber is provided with an air-escape pipe and the air-escape pipe is connected with a flared rubber disc. A communicating hole is arranged between the plenum chamber and the pressure-releasing chamber to communicate the two chambers, and a check valve, which enters the air from the plenum chamber to the pressure-releasing chamber unidirectionally, is arranged inside the communicating hole. A piston, which matches with and reclines against the wall of the pressure-releasing chamber to move up and down, is arranged at the lower section of the pressure-releasing chamber. A spring is stretched and pressed between the top of the pressure-releasing chamber and the piston.
