A control unit (100) is in use located under a kitchen sink. The control unit (100) controls the timing of the power demand from each device so that they can all be run from a single electrical circuit coupled to the control unit (100). The control unit (100) also accommodates sensors and other accessories such as flow meters (134), electronic faucets (114), leak detectors (118), shutoff valves (136), and state communication either wired or wireless which allows these sensors and other accessories to be added with little additional cost beyond the cost of the sensors and other accessories. A common faucet base (302) is disposed in use on an underside of a sink. The common faucet base (302) is configured to accommodate a plurality of faucet heads (304) having different faucet styles.

The invention relates to a top mount mechanism. The top mount mechanism is located at the bottom of a mixer, faucet, or tap. The top mounting mechanism includes the following parts: a top mount flange (2), a clamp plate (3), and connecting accessories. The top mount flange (2) and clamp plate (3) are linked via the connecting accessories. The top mount flange is located at the bottom of a mixer, faucet, or tap, flexible hoses from a mixer, faucet, or tap go through the top mount flange (2) and clamp plate (3). Connecting accessories includes a clamp screw (4) and guide pins (5) at the sides, the clamp plate (3) can rotate through a spigot (7) on the guide pins (5), and it is connected to the clamp screw (4) via thread connection, the clamp plate (3) moves up and down sliding along the guide pins (5).

The present invention provides a pullout faucet with a mounting system that is easier to manufacture and assemble. The pullout faucet includes a cage and a mounting retainer. The mounting retainer is separately formed from the cage.

An embodiment of a fluid valve includes a substantially flat face plate, a receptacle, a cavity, and a drain assembly. The receptacle is disposed in the face plate and has at least one protrusion each configured to engage a respective one of at least one groove of a valve-opening-and-fluid-dispensing device. The cavity has a top end in fluid communication with the receptacle, and has a bottom end. And the drain assembly has a top end in fluid communication with the bottom end of the cavity, has a bottom end, and is configured to allow fluid to drain from the cavity in response to the valve-opening-and-fluid-dispensing device being absent from the receptacle.

An embodiment of a fire-suppression water-intake valve includes a receptacle and a valve assembly. The receptacle is configured to receive a sprinkler head. And the valve assembly is configured to close in response to removing a sprinkler head from the receptacle, and is configured to open in response to installing a sprinkler head in the receptacle. Such a fire-suppression water-intake valve can allow quick and easy removal and installation of a fire-suppression sprinkler head without shutting a water supply to the valve.

Fluid control valve including a valve body having an inlet, an outlet and defining a fluid flow path therebetween. A first valve is adjustable by a first valve actuator between a closed position preventing fluid flow through the first valve and an open position permitting fluid flow. A second valve is associated with the inlet or intermediate the inlet and the first valve, and includes a second valve body and a second valve actuator adapted such that the first valve actuator bears against the second valve actuator in each of the open and closed positions to urge the second valve into an open configuration allowing fluid flow. The first valve actuator is adjustable to a third position in which it is spaced from the second valve actuator by a separation sufficient to allow fluid pressure at the inlet to cause the second valve to close.

A sprayer assembly for a faucet including a docking base and a sprayer removably coupled to the docking base. The sprayer includes a water outlet configured to direct water downwardly into a sink basin when the sprayer is coupled to the docking base.

A top mounting faucet assembly is mounted on a kitchen basin having an opening and contains: a fixer, a body, and a locking bolt. The fixer includes a base and a clamper, wherein the base includes a support portion and an insertion portion, and the support portion includes a peripheral fence and a shoulder, the peripheral fence has a recessed portion and a first anti-rotation portion, the shoulder has two longitudinal holes, and the insertion portion has a cylindrical fence and two columns. The clamper contains two screw rods and two locking protrusions. The body includes a second anti-rotation portion and a threaded orifice. The locking bolt screws with the threaded orifice of the body and abuts against the recessed portion of the base so that the body is stopped and does not move along the base, hence the body does not upwardly remove from the base.
