The faucet (20) comprises: a mixing valve, wherein the mixing valve is provided with a first inlet passage, a second inlet passage, and a mixing valve outlet passage, wherein the first inlet passage is connected to a first fluid line (L2), and the second inlet passage is connected to a second fluid line (L3); an outflowing pipe (23), wherein one end of the outflowing pipe (23) is connected to the mixing valve outlet passage; and a mode selection device (25), wherein the mode selection device (25) being operable to selectively allow one or both of the first fluid line (L2) and the second fluid line (L3) to communicate with the mixing valve outlet passage. The faucet (20) further comprises a mixing ratio adjustment device, the mixing ratio adjustment device and the mode selection device (25) operating independently from each other. The faucet (20) and the filtration system (1) according to the present invention can simplify operation of the faucet (20), allow the faucet (20) to be more in line with user's operating habits, reduce the number of parts and components, and enable configuration of appropriate mixing ratios according difficult use environments, thereby expanding the application scope of the faucet (20) and filtration system (1).

A two-way or four-way water faucet dispenses near-boiling water on demand but has a safety interlock. A control valve assembly is attached to the faucet. The interlock uses two disks pressed into contact, each having a single projecting sector. One disk is fixed to the valve body. The other disk, fixed to the handle, slides against the first. The disks must be pulled apart by sliding the handle while it is being turned to superimpose the sectors and turn the control valve, connecting the faucet to the vented near-boiling water supply. A reed switch inside the fixed sector is activated by a magnet inside the rotatable sector and activates a near-boiling water pump.

A water control valve may comprise a valve shell, a sliding block, an operating valve piece, a fixing valve piece, a valve base and a check valve. The sliding block, the operating valve piece and the fixing valve piece are stacked sequentially and positioned inside the valve shell. The sliding block has a valve rod which is formed at an upper portion thereof and sticking out of the valve shell, and a bottom portion of the sliding block is engaged with the operating valve piece such that, through operating the valve rod, the sliding block is configured to drive and have movements with the operating valve piece concurrently to perform different aligning patterns between the operating valve piece and the fixing valve piece, thereby enabling the water control valve to control on/off operation of a faucet, the amount of water flow and the mixing ratio of hot/cold water.

A water conservation faucet seamlessly integrating a tactile feedback mechanism into existing faucets to spur user controlled pre-set water flow rate, energy conservation, and cost savings. During movement of the handle, the user receives tactile feedback through the handle indicating the position of the handle as it moves from one pre-set position to the next. In addition to tactile feedback, the handle provides visual feedback to the user as the handle remains in the fixed position until the user chooses to move handle to another position.

A sanitary faucet having a faucet body; a mixing valve for mixing cold water and warm water to form a mixed water; and a thermostatic mixing valve for mixing cold and hot water to generate the warm water, containing an expansion material element and a gate valve operated by the expansion material element for adjusting a mixing ratio between the cold water and the hot water, wherein the expansion material element and the gate valve are arranged non-coaxially to each other, wherein the expansion material element can be used to operate the gate valve via a connection element, and wherein the connection element can be attached to the gate valve or the expansion material element and can subsequently be rotated into a closed position, in which the gate valve and the expansion material element are interconnected by the connection element. A method of installing a sanitary faucet is proposed.

A ceramic valve with a function of informing the operation position includes casing, a drive device partially and rotatably secured in the casing, a clicker longitudinally mounted to an upper portion of the casing and an outlet control device mounted to a lower portion of the casing for holding the drive device in place, wherein the drive seat extending through the clicker. The clicker informs an operation position by a click sound when the outlet control device is driven to a cold water supplying position, a hot water supplying position and a mixing water supplying position.

The invention relates to a control cartridge for single-lever mixing taps, comprising a housing having a cylindrical housing wall and a base having a borehole for an inlet for cold water and a borehole for an inlet for hot water. Three ceramic disks are situated one above the other on the base, namely, a lower base disk having a borehole for the inlet for hot water and a borehole for the inlet for cold water, a rotatable and displaceable ceramic control disk which rests on the base disk and has a control edge on the circumferential surface, and an upper bearing disk which is sealed off from the housing or the housing wall. In order for mixed water to be dischargeable either laterally or vertically with the same installation space or the same installation height and installation diameter, it is proposed that the base and the base disk each have a mixed water outlet in addition to the two inlets for cold water and hot water. The inlets for hot water and for cold water and the mixed water outlet are situated one above the other in the base and in the base disk. The base is sealed off from the housing wall, and, depending on the requirements, the housing wall has an opening for a lateral mixed water outlet or no opening in the housing wall for a vertical mixed water outlet.

A mixing unit with a mixer tap for mixing two fluids and a method for manufacturing the mixer tap for mixing fluids are disclosed. The mixing unit has a cartridge, which is provided with a coupling base having an inlet for a first inflow, an inlet for a second inflow, and an outlet for an outflow obtained by mixing the inflows. The mixing unit also has a housing designed to be placed in a coupled position with the coupling base. The housing is designed to change the rate of the first inflow and/or second inflow on the basis of the temperature of the outflow. The mixing unit also includes an attachment for attaching additional housing to the coupling base. The attachment allows for movement of the additional housing, in relation to the cartridge, between the coupled position and a separated position.

A faucet handle assembly for a Roman tub has a low profile and can be installed from above or below the tub deck. A valve body extends along a longitudinal axis and defines a cartridge cavity. A lower end defines water inlet and outlet passages and a threaded external surface. An upper end defines a threaded internal surface. A mixing cartridge with a rotatable stem and a cartridge spacer are carried in the cavity with the spacer axially between the cartridge and the inlet and outlet passages of the valve body. A fastener has a threaded external surface threaded to the threaded internal surface of the valve body upper end. An upper mounting ring has a hub disposed about the upper end of the valve body and a flange extending radially outwardly from the hub.

A check structure of a control valve base is provided, including a valve body, two seat bodies and two check members. Each seat body is assembled to the valve body, each check member is received in the seat body, each check member includes a blocking portion which is flexible, the blocking portion has a base portion and a side portion, and the side portion is obliquely connected to the base portion. When a water flow flows forward, the blocking portion and the seat body have a gap therebetween for the water flow to pass therethrough; and when the water flow flows reversely, the blocking portion contact the seat body tightly to block the water flow from flowing reversely.
