Abstract: A water purification core valve includes a shell having a top opening and a bottom opening. A cam bushing, a cam, a movable tile and a stationary tile are mounted inside the shell. A central portion of the cam is pivotally mounted to the cam bushing and a top portion protrudes beyond the top opening of the shell and is connected to a handle. The movable tile has a cam opening formed through the movable tile for the bottom portion of the cam to be inserted therein. Five water paths formed through the stationary tile and the movable tile and are respectively connected with three water inputs and two water outputs. The water purification core valve is operated by pivoting the handle to align the water paths to corresponding water supply, thereby fulfilling control over three ways of water input and two ways of water output.

Abstract: A two-route switching water output system includes a water input converter and a water output device. The water input converter includes a water input valve body and a valve cock. In the water input valve body is provided with a first water input route and a second water input route. One of the first water input route and the second water input route is selected to open or close through the valve cock. The water output device includes a water output valve body and a control valve core. Inside the water output valve body is provided with a first water output route and a second water output route. The first water input route and the first water output route are connected to form a first water route. The second water input route and the second water output route are connected to form a second water route.

Abstract: A two-path water output device includes a valve, and is mounted around by a shell. The valve has a first waterway and a second waterway. The first waterway is constantly connected to a water converter, while the second waterway is controlled to be open or closed by a control valve core. Such two-path structure is simple, novel and easily controllable for two types of water output like tap water and filtered water. When the second waterway is closed, the water pressure switches a water converter connected to the inlet end of the valve to the first waterway to output water. When the second waterway is open, the released pressure switches to the first waterway to output water.

Abstract: A water output converter includes a valve body and a valve cock. In the valve body is provided with a first water route and a second water route, while one of the two routes is switched to open or close through the valve cock. Water output of the second water route is controlled through an outside connected switch. The position of the valve cock is adjusted by the outside connected switch through feedback of water pressure in the second water route. When the outside connected switch is switched off, the valve cock is pushed to move upward by the water pressure in the second water route, to open the first water route. When the outside connected switch is switched on, the valve cock is pushed to move downward by the water pressure in the second water route, to close the first water route.

Abstract: A fast detachable pipe connector includes a first pipe connector, and a second pipe connector inserted into the first pipe connector. In a center of the first pipe connector is provided with a first ring shape slot, while in the first ring shape slot is provided with an elastic ring having indention. On a bottom portion of the first ring shape slot is provided with an opening in communication with interior of the first pipe connector. On the elastic ring is provided with a barrier block extending from the opening to interior of the first pipe connector, and a handle is provided near the opening of the elastic ring. The fast detachable pipe connector is simple in construction, optimized in design, so that its installation and detachment can be achieved easily and swiftly.

Abstract: A magnetic connection structure, includes a ring-shape magnetic sleeve body, made of mixed magnetic iron powder and plastic by means of ejection-to-mode; and a plastic fastener, provided in an arc-shape opening on both sides of the ring-shape magnetic sleeve body, for fastening a faucet seat or an ejection head. In the magnetic connection structure, the magnetic sleeve body and the plastic fastener are formed by means of ejection-to-mode separately. The magnetic sleeve body is formed by ejection-to-mode using magnetic iron powder and plastic mixed at a certain ratio; while the magnetic fastener is formed by means of ejection-to-mode separately. Then, the magnetic sleeve body and the plastic fastener are fastened together, to achieve said magnetic connection structure, that is low in production cost and easy to install. In case the plastic fastener is damaged, it can be replaced readily.

Abstract: A foam soap dispenser capable of adjusting the amount of air includes a pump, piston rod, a valve seat sheathed on the piston rod, a feed pipe coupled to the pump, a feed check valve for feeding a foam soap and a discharge check valve installed in the pump, an air-liquid mixing chamber formed between the feed check valve and the discharge check valve, an air-intake pipe communicated with an air-liquid mixing chamber, and an air-intake hole formed on the air-intake pipe that connects the air-liquid mixing chamber. The air-intake pipe includes an air-intake check valve, a screw sleeve and an air adjusting screw rod. The screw sleeve is fixed to the air-intake pipe, and the air adjusting screw rod is fixed into the screw sleeve and passed through a through hole of the screw rod of the check valve to insert the screw rod into the air-intake hole.

Abstract: A foam soap dispenser includes a cylindrical external casing having two ports, a first check valve installed at a liquid soap inlet end of the external casing, an inner tube installed at a liquid soap outlet end of the external casing, a second check valve fixed to an inner end of the inner tube, a slide plug installed between the inner end of the inner tube and an inner wall of the external casing and slidable with the inner tube along the inner wall of external casing, a gap formed between the slide plug and the inner tube and covered by a soft edge of the second check valve, a vent hole formed at the external casing, and a chamber formed between the two check valves and communicated with outside air when the soft edge of the second check valve is not covered onto the gap.
