An intermediate water-saving closestool water tank. A basin drain pipe is connected to the closestool water tank. Before the closestool is used, a time-delay valve (13) or a ping-pong valve is pressed so that tap water is supplemented when the water supply tank of the basin is not full. After the tap water is supplemented in the water tank and before the closestool is flushed, the ping-pong valve needs to be pressed again to prevent a ball float type water supplementary valve (14) from automatically supplementing tap water subsequently. The time-delay valve (13) does not need to be pressed again, and a flushing valve (17) is pressed normally when the closestool is flushed. Two flap valves are arranged at the bottom of the basin, one of the flap valves is directly connected to the drainage sewer, and the other one is communicated with the closestool water tank. The device achieves energy-saving and water-saving purposes.

A valve (1), in particular a piston valve, including a stationary housing part (2) and an actuating element (3) which can be adjusted relative to the housing part (2) and is in, or can be brought into, an operative connection with a valve body (4). The valve body (4) can be adjusted by way of actuation of the actuating element (3) between an open position which opens an outlet (5) and a closed position which closes the outlet (5). The valve (1) has a damping device (6) for extending a closing time of the valve (1), by an adjusting force which is applied for the closure of the valve (1) being opposed by a damping force which is produced by way of the damping device.

A pressing panel, including a panel, buttons and elastic pieces; the buttons are hinged to the panel, and each button is movable with respect to the panel through a pair of hinge shafts; each button is fixedly provided with an elastic piece; each elastic piece is provided with an elastic supporting arm extending backwards; each elastic supporting arm abuts the panel; when each button moves, a portion of a corresponding elastic supporting arm corresponding to an abutting position of the corresponding elastic supporting arm and the panel slides; when each button is in an initial state before being pressed, the abutting position between the corresponding elastic supporting arm and the panel, compared with a position of the corresponding pair of hinge shafts, is farther away from a fixing position between the button and the corresponding elastic piece; when pressing each button, the corresponding elastic piece moves along with the button.

A Toilet Flushing Apparatus Locking Nut System characterized by affixing a rigid rod to a securing nut that contains multiple rod receiving holes. The locking nut system maintains a secured position by means of resistance created when the rod contacts the toilet flushing apparatus's lifting arm, preventing rotational movement of the securing nut to less than 360 degrees. Multiple rod receiving holes within the body of the securing nut afford the ability to adjust the rod's position—to further reduce the securing nut's rotational travel to less than 360 degrees.

A toilet having a built-in odor evacuating system has a toilet body wherein a tank portion contains a module further comprised of a turbine member that is powered by a DC motor, and triggered by a motion sensor. The turbine member takes air from openings located inside a bowl portion of the toilet body, and pumps the air through a first pipe, forming part of the module. Once passed the turbine member, the air is directed into a second pipe directing the air into a “P” trap extending integrally from the bowl portion so that odors are blocked by water inside the bowl portion.
