A multi-stage toilet flush valve includes an inner valve and an outer valve that circumstribes the inner valve. The inner and outer valve control the flow of flushwater through associated inner and outer outlets. Thus, when the flush valve is actuated, the inner and outer valves are actuated at separate times, while the inner valve delivers flushwater to a rim of the toilet, while the outer valve delivers flushwater to a jet feed outlet in the toilet. As such the multi-stage toilet valve provides two independent inner and outer flushwater delivery outlets that are controlled by associated inner and outer valves that are capable of being actuated at separate times to control the ratio of flushwater delivered to a toilet rim and to a toilet jet feed outlet to enhance the effectiveness in which the toilet bowl is cleaned.

A toilet flush tank is provided that is capable of preventing an increase in the external dimensions of a toilet main body even when the toilet flush tank is placed below the upper surface of a toilet main body and is also capable of performing toilet cleaning in a stable manner. A toilet flush tank stores cleaning water to be provided to a toilet main body having a toilet bowl and a toilet drainage channel that communicates with the downstream side of the toilet bowl. This toilet flush tank is placed inside a space below the toilet bowl and provided with a recessed portion that conforms to the shape of the toilet drainage channel at the upper surface of the toilet flush tank.

A draining and flushing mechanism comprises a tank body, a first piston, a fixation rod to assemble the first piston, a main energy-storage spring and a drainage valve; the first piston is assembled inside the tank body and divided the tank body into a top tank and a bottom tank; the bottom tank is a water storage room spaced by the first piston and the tank body at the lower portion of the tank body; the main energy-storage spring is attached to the first piston to push the first piston to the bottom tank; an inlet pipe is connected to the bottom tank; wherein the bottom surface of the bottom tank is disposed with an assembly hole, the drainage valve is connected to the assembly hole and assembled to the outer side of the bottom tank, the drainage valve is disposed with at least a drainage hole.
