A flow-control faucet aerator is configured to be fitted on a spout of a faucet and includes a housing, an aerating device installed in the housing, and a washer installed above the aerating device. The washer is provided with at least one mouth and an aqueduct circling the mouth. The aqueduct is made of an elastic material and has a neck that has a wall thickness smaller than a wall thickness of the rest of the aqueduct. The neck of the aqueduct deforms at different levels according to different levels of water pressure at the spout of the faucet, so as to change a diameter of the aqueduct and in a flow of the faucet, thereby contributing to flow control and water conservation.

A dispenser main body (11) includes a cylindrical-shaped fitted portion (16a), and a nozzle (40) includes: a nozzle main body (41) and a nozzle extension body (42). The nozzle (40) is provided with a dispensing tube (51) including: a first dispensing tubular portion (51a) and a cylindrical-shaped second dispensing tubular portion (51b). A cut-out (52a) is provided in the front end of the first dispensing tubular portion (51a) or in a base end of the second dispensing tubular portion (51b), and an opening end of the cut-out (52a) is closed by the first dispensing tubular portion (51a) or the second dispensing tubular portion (51b) to provide an air inlet hole (52) in the dispensing tube (51).

A rich air sprayer of sanitary ware has a base, the base is disposed with at least two waterways; each waterway includes an inlet hole, a mutation cavity connected to the inlet hole and an air inlet hole connected to the mutation cavity, the flow area of the inlet hole is smaller than that of the mutation cavity, negative pressure is generated inside the mutation cavity when the water flows from the inlet hole into the mutation cavity, the negative pressure makes the mutation cavity suck air from the outside of the sprayer through the air inlet hole, the air and the water are mixed to form bubbles; the outlets of the mutation cavities intersect or the tangents of the outlets of the mutation cavities intersect, making the water flowing out of the outlets of the mutation cavities collide to enhance the granular sensation.

A jet regulator (1) which can be installed into the water outlet (2) of a sanitary outlet fitting (3), on the front side thereof. The jet regulator (1) can be arranged in a detachable or fixed manner in the water outlet (2). The jet regulator includes at least one holding element (4) for arranging or fixing the jet regulator (1) in the water outlet (2), with the holding element being inserted into a passage opening (5) on the perimeter of the fitting housing and engaging, in a fixed manner, with the end area thereof, the jet regulator (1), which projects into the interior of the fitting housing. The jet regulator (1) has a jet regulator housing (7) with an insertion opening (13) on the peripheral side, with the housing including in the interior at least one insertion guide (14) which is oriented across the jet regulator housing longitudinal axis, and at least one, preferably jet-producing, converter piece (15) can be inserted into the at least one insertion guide (14) from the insertion opening (13).

A switchable water-saving valve including a water inlet substrate formed as an annular body which has a housing and a water inlet portion. The water inlet portion is fixedly arranged within the housing and has a water inlet and a water outlet extending therethrough. A flow channel substrate is fixedly arranged within the housing below the water inlet portion. Guide holes are formed circumferentially at intervals on the flow channel substrate and extend therethrough and are in fluid communication with the water outlet. A switch holder is rotatably positioned below the flow channel substrate. First and second pluralities of water flow holes are arranged circumferentially in the top surface of the switch holder and penetrate the top surface. Water outlet holes are formed on the bottom surface of an aerator holder and are in fluid communication with the first water flow holes. When the switch holder rotates to a first position where the first water flow holes are aligned with the guide holes, water flowing into the guide holes flows out of the water outlet holes through the first water flow holes.

A shower head to jet an air bubble-liquid mixture by mixing air bubbles into the liquid includes a shower nozzle, a flow-adjustment piece, and air introduction passages. The shower nozzle includes an air bubble mixing space. The flow-adjustment piece is arranged in the air bubble mixing space. The air introduction passages cause air to flow into the air bubble mixing space therethrough.

A multi-function pull-out spray head includes a housing, a switching assembly, and a water discharge assembly. The water discharge assembly forms at least three water outlet areas. The switching assembly includes a first inner body, a second inner body, a first switching control unit, and at least two second switching control units. The first inner body has a communicating flow passage made by core-pulling technology in a direction parallel to a water flowing direction. The multi-function pull-out spray head is not easy to leak water and has the characteristics of high yield.

An exemplary foam dispenser includes a housing, a reservoir for holding a foamable liquid, and a pump located below the reservoir. The pump includes a liquid pump chamber, two or more air pump chamber and a manifold. The manifold includes a liquid outlet port, a liquid outlet valve and an air outlet port. An elongated liquid dispensing conduit in fluid communication with the liquid outlet port and an elongated air dispensing conduit in fluid communication with the air outlet port are also included. A mixing chamber having a mixing chamber liquid inlet, a mixing chamber air inlet, and a foam outlet is provided. The mixing chamber is located remotely from the sequentially operated multi-diaphragm pump. The elongated liquid dispensing conduit is in fluid communication with the mixing chamber liquid inlet and the elongated air dispensing conduit is in fluid communication with the mixing chamber air inlet.
