Abstract:
1. A flushing controlling mechanism comprising: a toilet bowl having a trap for receiving therein waste, a room selectively communicating with the trap via a first waste pipe and a second waste pipe alternately communicating with the room; a combination of a first hollow cylinder and a second hollow cylinder received in the toilet bowl, with the first hollow cylinder and the second hollow cylinder having different diameters, with the first hollow cylinder having a water tank, a suction space, a first piston movably inside the first hollow cylinder to separate the water tank from the suction space in a watertight manner, an inlet adapted to be connected to a water source to allow water to flow into the water tank so as to move the first piston upward inside the first hollow cylinder, an outlet selectively communicating with the trap of the toilet bowl and a first opening communicating with the suction space and the room of the toilet bowl, and with a second piston being fit and movably received inside the second hollow cylinder and connected to the first piston by a linking rod; and means for accelerating downward movement of the first piston and the second piston for generation of a vacuum effect in the suction space such that waste in the trap of the toilet bowl is sucked into the room and disposed from the second waste pipe.
