Abstract: A water saving device is disclosed, which comprises a base having a water flow channel, a throttle ring and a support seat made of an elastic material, and a capacity space is formed in the base, and the support seat is disposed in the capacity space. An annular channel is formed between the support seat and the base. The water channel is in communication with the annular channel. The throttle ring is disposed in the annular channel. When the water pressure is increased to a certain extent, the throttle ring is deformed, and the cross-sectional area of the water flow channel is reduced. The water saving device can effectively prevent the throttle ring from shifting or falling off, and it also has good structural strength and stability that is not easily deformed or broken by external force.

Abstract: A push button switching spool includes a switching body. The switching body includes a housing, a water inlet and a water outlet, wherein the housing comprises an upper casing and a lower casing with a gap for passing water. A mandrel is disposed in the housing, and the mandrel axially moved within the housing. The mandrel comprises a plurality of grooves with sealing rings. And, a left protrusion and a right protrusion are formed on each groove, wherein a diameter of the left protrusion is the same as a diameter of the right protrusion. The push button switching spool can normally switch water paths at high water pressure.

Abstract: A hydroelectric power generator, comprising: a plastic seal outer shell; a skeleton main body, disposed in the plastic seal shell; an embossed flat axis, disposed penetrating in the skeleton main body; an impeller, connected and fixed to one end of the embossed flat axis, to drive the embossed flat axis into rotation; a magnet, sleeved around the embossed flat axis; a copper coil, disposed around the skeleton main body; a driving plate, connected and fixed to one end of the plastic seal shell, to drive the impeller into rotation; and a plurality of water input bosses, extending slantwise on the driving plate, having water input holes provided thereon. The hydroelectric power generator is simple in structure, easy to manufacture. In which, the slant water input holes on the driving plate are used in cooperation with the impeller, to raise the impact of the water flow.

Abstract: A secondary encapsulation waterproof structure for hydroelectric power generator comprises: a magnet, sleeved on and around a rotation axis of a generator; a coil, disposed around the magnet; and a magnet encapsulation component, sleeved around the magnet. The magnet encapsulation component includes a column-shaped plastic sleeve, a column-shaped rubber sleeve, or a column-shaped ceramic sleeve, sleeved around the magnet. The secondary encapsulation waterproof structure for a hydroelectric power generator is simple in construction, and it utilizes the secondary encapsulation waterproof structure to overcome the insufficient waterproof capability of the prior art for a hydroelectric power generator obtained through barrel plating, to raise its waterproof and corrosion resistance capability, in achieving prolonged service life for the hydroelectric power generator.

Abstract: A poking-rod type multi-function shower arm comprises: a shower arm main body, including: a water output end, at least two water output ends, disposed around an outer wall of a water output chamber in the shower arm main body, and formed with an angle to each other, while connected and communicating with the water output chamber; a tight seal plug, disposed in the water output chamber, and used to block respective water output ends; a swing rod, sleeved in a center of the tight seal plug, and extended outside the water output chamber, to drive the tight seal plug to move, so as to close the water output end, to prevent it from outputting water.

Abstract: A push-button type multi-function shower arm includes a shower arm main body, provided with a water input end, a shower water output end, and a shower head water output end; a water output chamber, disposed in the shower arm main body, with perimeter of its outer wall disposed with the shower water output end and the shower head water output end in communication with the water output chamber; a shunt valve, disposed in the water output chamber, movable upward and downward, while in a center of the shunt valve is provided with slot channel, to enable communication between the water input end and the shower water output end; and a press device, disposed at top of the shunt valve, to drive the shunt valve to move along axial direction of the water output chamber.

Abstract: A front-knob type multi-function shower arm and method of implementing the same. The method includes the following two water output modes: (1) a shower head water output mode: when rotating upward a knob on a front face, a three-way splitter is brought to connect a water input channel of a main body to a shower head water output channel, so that water flows to the shower head water output channel, and then it flows directly out from a shower head; and (2) a shower water output mode: when rotating downward a knob on a front face, the three-way splitter is brought to connect the water input channel of the main body to the shower water output channel, so that water flows to the shower water output channel, and then it flows out a shower from an outside connected shower hose.

Abstract: A side-knob type multi-function shower arm and a method of implementing the same. The method comprises two water output modes: (1) a shower head water output mode: when handle of a function switching knob is rotated to point vertically downward, a three-way splitter is brought to connect the water input channel of main body to a shower head water output channel, so that water flows to the shower head water output channel, and then flows directly out from a shower head; and (2) a shower water output mode: when the handle of the function switching knob is then rotated 90 degrees counterclockwise, the three-way splitter is brought to connect the water input channel of the main body to a shower water output channel, so that water flows to the shower water output channel, and then flows out a shower from an outside connected shower hose.

Abstract: A position restoring and water splitting shower arm and a method of implementing the same. The shower arm comprises: a tube body and a switch valve. The tube body is provided with a water input port and a first water output port, while a second water output port is disposed on a middle section of the tube body. The switch valve is disposed vertically in the tube body, to switch connection and communication between the water input port and a first water output port, or between the water input port and the second water output port. The switch valve includes a valve seat; and a gravitation valve core disposed in the valve seat, with its one end provided with a valve core head, used to block the second water output port or the valve seat upper port.

Abstract: A structure of water-saving device includes a base, an adjusting ring and a gland. The adjusting ring is mounted in a water-inlet channel. The gland is movably positioned in the base to limit the adjusting ring. A central part of a top surface of the gland sinks downward to form a recess. When water flow impacts the gland, the gland pushes the adjusting ring, such that the adjusting ring is deformed. Since a difference of pressure occurs between a top and bottom surfaces of the gland, the larger the water pressure is, the larger the force from the gland toward the adjusting ring becomes; thus the degree of deformation of the adjusting ring also becomes large, such that the area between the adjusting ring and the bottom surface of the base for water flowing through decreases and the flow of water gradually achieves a stable value.
