A device and water system for preventing the proliferation of living beings in the water pipes of buildings and that can be applied to taps with a supply of hot and cold water to improve the health standards of public and private constructions with hot water circulation systems, or without, by recirculation within the hot, warm or cold water system. The same permits the prevention of the freezing of the piping. The device has a bypass between the hot and cold water pipes that supply a tap, with a pump that causes recirculation of the water via the bypass, a mechanism for regulating the flow of water located in the bypass, a temperature probe in the water pipe above the bypass, a mechanism for activating and deactivating the pump, and a system for controlling the flow regulation mechanism, the activation and deactivation of the pump and functioning of the pump.

A flow regulator includes a housing portion, a diversion device, an annular seat and an elastic water stop ring. The annular seat, the diversion device and the housing portion are fixedly assembled together. The diversion device includes a periphery wall disposed with diversion holes, a central base within the periphery wall and a deflecting annular wall fixedly connecting the periphery wall and the central base. The external periphery surface of the deflecting annular wall is gradually larger downwardly from the central base to the periphery wall. The central base at least partly extends out of the internal hole of the annular seat. A water flow clearance is formed between the central base and the hole wall of the internal hole of the annular seat. The water flow clearance is disposed above the deflecting annular wall so that water flows out of the flowing clearance and onto the deflecting annular wall.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24), a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressurevacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

A system for water recirculation that includes: a sink/faucet water inflow; a hot water flow flowing into the sink/faucet inflow; a cold water flow flowing into the sink/faucet inflow; and a sink/faucet valve between the sink/faucet water inflow and a sink/faucet input, wherein the valve opens flow to the sink/faucet input in an open position and the valve directs the sink/faucet inflow to a water return in a closed position. The water return is directed to a hot water heater.

A faucet comprises a faucet body, a water outlet panel, and a panel water outlet pipe. The water outlet panel is configured to be arranged separately from the faucet body, and a valve seat comprises a water passage respectively connected to a first valve and a second valve. The first valve is in communication with hot water and cold water to form mixed water that is in communication with the water passage, and the second valve is configured to receive the mixed water and is configure to be controlled to enable the mixed water to be in communication with the water outlet panel. The faucet body comprises a water outlet terminal, the water outlet panel comprises a water outlet port, and the first valve is configured to be controlled to enable the mixed water to be in communication with the water outlet terminal.

A shower head structure includes a main body, a face plate, and a switching device installed inside the main body for controlling an outflow of water from the face plate. The circumferential portion of the face plate is provided with a plurality of water outlet units. Each water outlet unit includes a plurality of jet orifices. The water flowing from the plurality of jet orifices forms a bunched spout. The bunched spout includes a plurality of fine spouts. The water won't spray about. Since the diameter of the jet orifice is small, the force of the fine spouts is stronger. The water-saving effect is good. The shower head can be used for low pressure environment.

A single-entry faucet is provided with a delivery duct, a supply duct and a nebulizer insert coupled to the outlet of the delivery duct.

An economizer system and method for saving heat and water, comprising a bathing facility for receiving hot water from a water heater through a pipeline; a first valve for controlling the flow of hot water received by the bathing facility; a second valve for allowing the flow of an initial volume of cold water existing in the pipeline between the water heater and the bathing facility 1 through a filling line; and a holding tank for collecting the initial volume of cold water flowing from the filling line before the hot water is delivered to the bathing facility.

A hot and cold water switching valve includes a valve body, a switching valve element, a switch valve element and a thermal sensing valve element, wherein the valve body has an inflow channel, a recovery channel and an outflow channel; one end of the three channels is communicated in the valve body; the switching valve element is provided in such a position where the three channels are communicated with each other and used for switching the outflow mode; the switch valve element is provided in the outflow channel and used for opening or closing the outflow, and the thermal sensing valve element is provided in the recovery channel and used for closing the channel when the water temperature is higher than the set temperature; and a sprinkler used for automatic outflow of cold water, comprising a sprinkler body and the above-mentioned hot and cold water switching valve.

A faucet having a faucet base, a water hose, a faucet head, and a chamber is provided. A water valve is provided in the chamber and includes a driving member and a control valve movable between a first position enabling mixing of water and air and a second position enabling shut-off of a water flow. The faucet head further includes a control member movably coupled with the faucet head to enable operating the control valve within the water valve using magnets by operating the control member from or near a side of the faucet head.
