Abstract: A rotary shower head for showering includes an outer case to house a universal joint, an inner case assembly, a driving mechanism and a water discharge disc. Water entering the shower head provides a water discharge force to thrust the driving mechanism to generate automatic turning of the water discharge disc to achieve water-saving effect.

Abstract: A water stopper for a toilet tank to allow fine-tune adjustment of water flushing amount of the toilet tank includes at least a cap, a dome and an adjustment strut that are incorporated with a stopping gasket and a washer. The dome is a hollow semi-sphere coupled on the bottom of the cap and turnable, and has a water inlet at the bottom thereof and an air vent at one side. It further has features as follow: the cap has a coupling portion on the bottom to fasten to one end of the adjustment strut. The adjustment strut has a stopping disc at other end. The stopping disc has an aperture corresponding to the water inlet of the dome. By turning the dome, the water inlet and the aperture of the stopping disc can be overlapped at a desired ratio, thereby water entering speed into the dome can be fine tuned to control water flushing amount of the toilet tank.

Abstract: A wall-mounted elbow duct and particularly to a wall-mounted elbow duct to connect a wall-mounted water discharge pipe to a hand-held shower head mainly includes an elbow duct which houses a reverse checking mechanism and a coupler and a coupling cap. By means of the invention the hand-held shower head can be connected to the wall-mounted water discharge pipe without a great number of elements. An ornamental cover also is formed to conceal the connecting portion of the water discharge pipe to enhance aesthetic appeal.

Abstract: A toilet tank valve seat structure mainly includes a body and an overflow tube located on one side of the body. The overflow tube consists of an inner tube and an outer tube. The inner tube has a gear rack on one side to couple with a hook located on one end of the outer tube so that the outer tube may be moved up and down to adjust the length of the overflow tube. The body has a valve opening covered by a plug. The plug has an anchor notch bordering by two slots on two sides that provide elasticity to make coupling of the anchor notch easier. The structure provides the overflow tube with an adjustable length according to the water level and makes replacement of the plug easier.

Abstract: A water filler includes a water filling device, and a regulating device. The water filling device includes an inner filling tube, an outer filling tube, and an upper cover. The regulating device includes a floating barrel, a sliding barrel, a water support disk, and an adjusting unit. Thus, the floating barrel is lifted instantaneously and rapidly to stop the water filling action exactly and actually, thereby saving the water source. Thus, the water filler has a quick water stop function.

Abstract: A level adjuster of a water supply of a water box serves for adjusting the amount of water in a water box conveniently and easily. The level adjuster comprises a press, a supporting rod, an pressable button, a positioning seat, a pontoon, an inner water injecting tube and an outer water injecting tube of a water injector. The amount of water in the water box can be precisely controlled and the operation is easy without using any other auxiliary tool. No problem of element fatigue and change of water level occurs.

Abstract: A shower head structure includes an outer housing, a water exciting vane wheel, a water outlet cover, and a water guide barrel. The outer housing contains a ball connector, and a sealing ring pressing the ball connector. The water exciting vane wheel includes a central hollow bushing, a plurality of curved vanes, and a catch plate. The water outlet cover defines multiple straight water outlet apertures and three massaging water outlet apertures and includes an annular water dispensing barrel provided with a short stub. The water guide barrel includes a first step provided with an enlarged opening tightly pressing the sealing ring and a second step provided with a reduced section provided with a vane wheel shaft extending through the hollow bushing of the water exciting vane wheel and defining a receiving hole securing the short stub of the water dispensing barrel. The reduced section of the water guide barrel defines three oblique cut water outlet ports facing the vanes of the water exciting vane wheel.
