A faucet configured to be installed onto a sink, having a first valve and a second valve, wherein the first valve dispenses water through a spout, wherein the second valve dispenses water through a side port, wherein the side port is capable of receiving a connector, wherein the connector attaches a hose to the side port, and wherein the hose supplies the water to an external device.

A kitchen faucet comprises a faucet body, a control valve, a solenoid valve, and a pull-out head. The faucet body comprises a first water inlet pipe, a second water inlet pipe, a first water outlet pipe configured to be in communication with the first water inlet pipe, and a second water outlet pipe configured to be in communication with the second water inlet pipe. The pull-out head is pluggably matched with the faucet body and is in communication with the first water outlet pipe. The control valve is disposed on the faucet body and is configured to control the first water outlet pipe to be opened and closed, and the solenoid valve is disposed on the second water inlet pipe to control the second water outlet pipe to be opened and closed.

A kitchen sprayer with filter includes a sprayer housing which has a top comprising a water inlet connectable to a faucet or a hose; a filter element assembly arranged in the sprayer housing having a filter element upper lid, a filter element and a filter element lower lid. The filter element is a hollow cylinder, an interior of the filter element is a purified water chamber, and an outside of the filter element is a raw water chamber; the filter element assembly is configured to be integrally mounted and disassembled with respect to the sprayer housing; a handle by which the filter element assembly is configured to be taken out is arranged at a bottom of the filter element lower lid; and a water outlet panel assembly is mounted on a bottom of the sprayer housing.

An apparatus (10) for generating nanobubbles for use with fluid dispensing fittings is described. The apparatus includes a longitudinal shaft having a first end portion (12), a body (16) and a second end portion (14). The first end portion (12) and the second end portion (14) are adapted for connection with the body (16). The first end portion (12) and the second end portion (14) each includes a conical-shaped guide wherein the body comprises airfoil-shaped projecting members (19) arranged circumferentially on the outer circumferential surface of the body (16).

A water treatment system having a water treatment engine including a pressure vessel, electronics module and optionally replaceable shrouds. The water treatment engine may include a tether and a single connection point for water and power lines. The tether may have a release that is accessible only when the electronic module is removed. The water treatment engine may be circular and the water and power lines may be arranged within a region bounded by tangent lines that square the circular shape. The electronics module may be configured to receive one of a variety of alternative interchangeable displays. The electronics module may have a single display port that provides power and data that can be utilized by a plurality of different types of displays. The system may include a replaceable cartridge with soft end caps that include an integral seal and are shaped to self-center within the pressure vessel.

A faucet-mounted filter system includes a body forming a fluid chamber having a water inlet, a quick connect device positioned adjacent the water inlet for mounting the filter system to a water faucet, a filtered water flow path disposed within the body and in fluid communication with the water inlet, an unfiltered water flow path disposed within the body and in fluid communication with the water inlet, a diverter valve disposed within the fluid chamber and operable to open and close the filtered and unfiltered water flow paths, a seal, an actuator engaging the diverter valve to open and close the filtered and unfiltered water flow paths, a flow meter connected to the body and in fluid communication with the filter flow path, a filter housing connected to the body and having a reservoir, and a filter cartridge disposed within the reservoir.

An automatic water faucet device 1 for automatically discharging water when an object to be detected is detected has: a sensor 14 that detects the object; a first water discharge part 12 that performs foamy water discharge; a second water discharge part 13 that performs spray water discharge; and a controller 40 that performs control for switching between the foamy water discharge from the first water discharge part 12 and the spray water discharge from the second water discharge part 13, wherein the controller 40 performs the foamy water discharge from the first water discharge part 12 while the sensor 14 detects the object, and when the sensor 14 no longer detects the object, the controller 40 stops this foamy water discharge, and thereafter performs spray water discharge from the second water discharge part 13 for a predetermined period.
