A simple installation module for installation on a countertop includes a fixing seat to be fixed in a mounting hole in a countertop, a connecting rod mechanism, and a screw rod. At least one guide rod is connected to the lower portion of the fixing seat, at least one guide part to be matched with the guide rod is arranged on the connecting rod mechanism, and the screw rod is matched and connected with the connecting rod mechanism.

A control unit is located under a kitchen sink. The control unit 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. The control unit also accommodates sensors and other accessories such as flow meters, electronic faucets, leak detectors, shutoff valves, 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 fluid control valve includes first and second valves. The first valve is adjustable under the control of a first valve actuator between a closed position in which flow of fluid through the first valve is prevented and an open position in which flow of fluid through the first valve is permitted. The second valve comprises a second valve actuator adapted such that the first valve actuator bears against the second valve actuator in each of said first and second positions to urge the second valve into an open configuration allowing flow of fluid. The first valve actuator is adjustable to a third position in which the first valve actuator 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, preventing flow of fluid through the fluid control valve.

An outlet structure of a faucet valve seat, has a valve seat and a sleeve pipe, wherein the valve seat forms a sleeve hole, the sleeve pipe is used to set an outlet pipe, and the sleeve pipe is sleeved in the sleeve hole. The sleeve pipe penetrates through a plug hole, and one end of the outlet pipe is inserted into the plug hole, such that a long axis is parallel to the central axis of the valve core, and a central axis of the plug hole forms an included angle with the long axis as . The valve seat can be selected by the sleeve pipe with the corresponding angle of the plug hole according to the needs of the outlet pipe, and meet the diversified demand of the outlet pipe elevation angle.

A tubeless sprayer assembly includes a base that is coupled to a support surface. The base has a fluid port is integrated therein. The fluid port is fluidly coupled to a fluid source wherein the fluid port is configured to receive a fluid from the fluid source. A canister is positionable in the base. The canister is in fluid communication with the fluid port when the canister is positioned in the base to fill the canister with the fluid. A pumping unit is coupled to the canister. The pumping unit pumps the fluid outwardly from the canister when the pumping unit is turned on to facilitate the fluid to be sprayed without a connection to the fluid source.

The present disclosure discloses a fixing device and a faucet installation device. The fixing device comprises a base and a pressing block mechanism. The pressing block mechanism comprises two pressing plates. The two pressing plates are respectively connected to a locking rod, and an inner side wall of the base protrudes to define two connecting bases. At least one of the locking rods is configured to move relative to the base between a working state and a movable state. Movement of the at least one of the locking rods between the working state and the movable state cooperates with the change of the pressing block mechanism between the unfolded state and the folded state.

A fastening assembly for a top-mounted faucet that allows quick and easy installation of the faucet. The fastening assembly includes a plate and a threaded nut. The plate includes an upper grip member made of soft gripping material and a lower support member made of a rigid material. The plate has an elongated central aperture passing through the upper grip member and lower support member. The lower support member includes two flanges that clamp to opposite two faces of the threaded nut.

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.
