Abstract: A single-lever tap closable by a load added thereon after pulling up a knob, wherein, the knob is provided with a pivot connector pivotally provided on the top of a main body and is coupled to an output valve, a force exertion portion is formed by extending of the pivot connector forwardly. When the knob is pulled up, by coupling of the pivot connector to the output valve, the tap is opened, and when it restores to the original position, the tap is closed.

Abstract: A toilet structure having lower and upper water tanks, the latter being fixed on the former, a lower outlet on the bottom of the lower water tank for supplying water from the lower tank to a whirling water feed outlet in an associated nightstool, and an upper outlet on the bottom of the upper tank for supplying water from the upper water tank to a ring of holes formed in an upper periphery of the nightstool. When a rotatable knob is turned in a first direction, a small amount of flushing water is discharged from the lower tank through the lower outlet to flush urine from the nightstool. When the knob is turned in a second direction, both the water tanks discharge water simultaneously for flushing nightsoil from the nightstool. Accordingly, water consumption is reduced.

Abstract: The flush valve has in its inlet pipe of its main body a turnable knob, a hollow pipe-like filtering net provided on one side of an adjusting through hole opposite to an adjusting knob, and an elastic element and a pad provided inside the filtering net, water pressure will push away the pad and compress the elastic element to get into the filtering net for filtering out impurity in water and then get into the main body, when the valve is closed, the pad will cover the adjusting through hole by restoring force of the elastic element and the reversing water flow, the reversing hammering created by abrupt stopping of water will be absorbed by the pad, its pipe structure can thus be prevented from damage and leaking, the filtering net can be dismounted for cleansing and maintenance easily.
