The present invention provides a cartridge assembly for a faucet. The cartridge assembly permits flows from a first flow source and a second flow source to flow through the cartridge assembly and to be regulated through the faucet without permitting flows from the two sources to flow simultaneously through the cartridge assembly.

The invention relates to a device and method to quantify the lead exposure of an aqueous feed to humans, remove lead from the aqueous feed, and identify the presence of lead service lines. The device includes an inlet to receive a lead-containing aqueous feed; an outlet to discharge a lead-depleted treated aqueous feed; and at least one cartridge containing sampling media positioned so that the lead-containing aqueous feed passes from the inlet and through the cartridge to produce the lead-depleted treated aqueous feed for discharge through the outlet.

A fluid purification device includes a screen plate, a first filtration layer, a second filtration layer, a third filtration layer, a main body, and a dispensing plate. The screen plate has a plurality of inflow holes for filtering particles in fluid passing therethrough. Around a periphery of the screen plate, several convex sections are arranged and spaced apart from one another. The main body is hollow and has an open top and an open bottom opposite to the open top. Around an inner wall of the open top, several concave sections are arranged and spaced apart from one another. The concave section is shaped in conformity with the convex section, so that the screen plate can be secured to the open top of the main body.

A passive fluid dosing assembly and system is provided. The passive fluid dosing system may include a passive dosing body, a pressure plate, and a treatment enclosure. The passive dosing body may define a primary flow path and a liquid treatment path. The primary flow path may be defined between a fluid inlet and a fluid outlet. The liquid treatment path may be defined between a high pressure port and a low pressure port, bypassing a portion of the primary flow path. The pressure plate may be disposed within the passive dosing body between the high pressure port and the low pressure port. The pressure plate may define an internal orifice. The treatment enclosure may be positioned in fluid communication between the high pressure port and the low pressure port along the liquid treatment path. The treatment enclosure may define a solute chamber housing a dosed media.

The present invention describes a hybrid device (1) for a recirculation shower, allowing purification and either recycling of water or discarding of water, wherein said hybrid device (1) comprises a recirculation loop (2), a filter system (4) with a nano-filter (5) such as for instance an electropositive nano-ceramic filter, e.g. a nano alumina (fiber) filter, at least one filter quality sensor (3), at least one pre-filter (6), and wherein the hybrid device (1) is arranged to redirect the water from recirculation to drainage when the at least one filter quality sensor (3) indicates the need thereof.

A sensing faucet assembly includes a body having an inlet, a first outlet, and a second outlet. The sensing faucet assembly includes a first passageway defined between the inlet and the first outlet and a second passageway defined between the inlet and the second outlet. A solenoid valve can control the opening and closing of the first passageway. A valve core can control the opening and closing of the second outlet.

A shower head magnetic attraction fixing structure, including a shower component with a shower body and a first magnetic attraction mechanism retractably provided on a back surface of the shower body, and a fixing component; the first magnetic attraction mechanism flushes with the back surface of the shower body when there is no magnetic attraction; the fixing component has a fixing seat having a fixing groove to embed the first magnetic attraction mechanism, and a second magnetic attraction mechanism inside an upper wall of the fixing groove; connecting buckles are provided to be biased to eject out of the inner side walls of the fixing groove and capable of retracting into the inner side walls; the connecting buckles are locked into a limiting ring groove of the first magnetic attraction mechanism to fix the first magnetic attraction mechanism and the second magnetic attraction mechanism.

This invention is an excess water slot of dimensions conforming to the recognized dimensions to be installed in place of the previous one but with a different inner design and it also works by a totally different mechanism. It was designed to separate pure water from others by a partition in the upper part of the excess water slot extending inside the washbasin and the lower part of the excess water slot ending with 2 pipe outlets one for pure water and the other for turbid water. The upper side means the upper part with drain holes in the middle of the washbasin. This separation is a small wall of 1-2 centimeter height as shown in 3 at (FIG. 2) with small flexible arms of extending ends as shown in 1 A (FIG. 5.) to separate water when it falls from the faucet down to the washbasin, and to allow using rubber taps for each half of the excess water slot. One of the two outlets is directed to the public drain system and the other for recycling, for clarification of the invention.

A water transferring device is provided and comprises a body having a water passage chamber, a first water inlet joint having a first water inlet passage and connected to the body, and a water outlet joint having an outer water passage and an inner water passage. The first water inlet joint and the water outlet joint enable the inner water passage to be in communication with the first water inlet passage. The water passage chamber is in communication with the outer water passage. At least one of the first water inlet joint or the water outlet joint comprises a connection structure connected to the body and enabling the at least one of the first water inlet joint or the water outlet joint to be at least rotated for a specific angle around an axis of the at least one of the first water inlet joint or the water outlet joint.

The invention discloses a control device for faucet assemblies. Faucet assemblies comprises a faucet spout with a first and a second water outlet; a first water supply pipe communicating with second water outlet, a second water supply pipe communicating with first water outlet and containing a water outlet pipe section connected with first water outlet and a first water inlet pipe section and a second inlet pipe section communicating with water outlet pipe section, control device comprising a first and a second solenoid valve respectively provided on first and second water inlet pipe section; a capacitive touching unit disposed on faucet spout; and electrically connected to a second control unit, when touch time is less than first predetermined time, opening second solenoid valve, and is greater than second predetemined time, opening first solenoid valve. The invention has effects of meeting different demands, combining touch and manual, and being convenient operation.
