Abstract
A water saving toilet comprising a water assembly and a bowl assembly. The tank assembly includes a water tank, a lid for the water tank and a water supply control mechanism provided in the water tank, a water trap control mechanism and a water flushing control mechanism. The bowl assembly includes a bowl and a water flushing system having a primary and a secondary water discharging lines. In the water saving toilet of this invention, by means of the linkage and regulation of a ball valve and a float arm in the unique regulation container provided within the water trap control mechanism, both water storage in the tank and the formation of the water trap in the bowl are under proper control such that in operation, control of the quantity of the water to be flushed is achieved by means of the dual flushing line arrangement in combination with the linkage of the levers, thus resulting in a pumping action in the line system through siphonage, that is, either a "primary operation mode" (discharging solid wastes) or a "secondary operation mode" (discharging liquid wastes) will be performed of the toilet based on the controlled water quantity entering the bowl.
