ABSTRACT:
A water-saving flush mechanism installed in the water tank of a flush toilet. In addition to providing an inlet control structure with an inlet pipe and a water level float ball, an outlet pipe is provided on an outlet seat. The outlet pipe is in communication with a telescopic overflow pipe. The outlet pipe includes a lower outlet pipe and an upper outlet pipe. The upper and lower outlet pipes are nested and are adjustable for height. A connecting rod on a side of the lower water outlet pipe is pivotally attached to the overflow pipe. A plate is provided on and end of a shaft. A lower pull rope is tied to the outlet pipe and pulls open the lower edge of the lower outlet pipe. A rod with a covering shaft is pivotally attached to one side of the upper outlet pipe. An outlet pipe cover at another end of the covering shaft closes the top opening of the upper outlet pipe and is provided with a pull rope that pulls the outlet pipe cover to open the top opening. Through pulling the different pull ropes, flushing by means of opening the top opening or the lower section of the outlet pipe is controlled so as to vary the flushing volume. The pull ropes are tied to an actuating device which can be installed in different positions in the water tank.
