Abstract
A control mechanism for a toilet is constructed to include a valve seat, an overflow tube, and a tank ball assembly pivoted to the overflow tube and adapted to close/open the valve seat. The tank ball assembly includes a holder base pivoted to the overflow tube, a stopper pivoted to the holder base, an adjustment valve fastened to a bottom side of the stopper, a first lift chain adapted to lift the holder base with the stopper and the adjustment valve from the valve seat for enabling a first amount of flushing water to be discharged out of the valve seat, and a second lift chain adapted to lift the stopper with the adjustment valve from the holder base for enabling a second amount of flushing water to be discharged out of the valve seat.
