A faucet assembly including a faucet body having a spout, a base, and hot and cold water flow control valves. The base houses a thermostatic mixing cartridge that tempers hot and cold water and has passageways that place tempered water from the thermostatic mixing cartridge and a cold water passageway in selective fluid communication with the outlet of the spout. During use, mixed water from the thermostatic mixing cartridge is regulated by the hot water control valve, cold water is regulated by the cold water control valve, and both the mixed water and the cold water are further mixed at a juncture of the mixed water passageway and the cold water passageway prior to exiting the faucet assembly via the outlet of the spout.

The present invention provides a wall faucet including: an injection molded plastic faucet body defining a hot water inlet, a cold water inlet, at least one water outlet and a receiving chamber; a valve cartridge seat having two one-way valves accommodated therein suitably and a valve cartridge received in the receiving chamber; and a plate sleeve detachably assembled to the faucet body. The hot water inlet and/or the cold water inlet is formed with a body connector detachably assembled thereto. In the wall faucet of the present invention, the body connector is detachably assembled to the hot water inlet and/or the cold water inlet of the faucet body and, therefore, the body connector can be changed quickly and easily.

A simple water outflow device which is an outflow device with an inflow pipe and an outflow pipe. The simple water outflow device consists of a body, an inflow pipe, and an outflow pipe. A discharge control valve is installed inside the body. The outflow pipe and body are a one-piece design created using injection molding technology. The inflow pipe is soft and flexible. There is an axial inflow channel and radial groove inside the body. The groove and the inflow channel are perpendicularly connected. There is a circular magazine on the upper end of the inflow pipe. A leakproof O-shape ring is placed on the circular magazine. The upper end of the inflow pipe is inserted into the inflow channel. A C-shape shackle is inserted into the groove of the body, and shackled into the circular magazine of the inflow pipe. This secures the inflow pipe on the body.

Disclosed herein is a valve assembly. The valve assembly includes a valve body, a cartridge, a hot side check stop, and a cold side check stop. The valve body has a cartridge receiving area, a first check stop receiving area, and a second check stop receiving area. The cartridge is located in the cartridge receiving area. The hot side check stop is located in the first check stop receiving area when the valve assembly is in a first configuration. The cold side check stop is located in the second check stop receiving area when the valve assembly is in the first configuration. When the valve assembly is in a second configuration, the hot side check stop is located in the second check stop receiving area and the cold side check stop is located in the first check stop receiving area.

In accordance with an embodiment, a universal adapter configured for use in a fluid delivery apparatus and an annular shaped member having a first end and a second end, an outer wall, a first opening at the first end, a second opening at a second end, and a duct extending from the first opening to the second opening. Grooves are formed in portions of the outer wall, an internal thread is formed in the duct, and a groove is formed in another portion of the duct. In accordance with another embodiment, method for manufacturing a universal adapter includes forming an annular shaped member having a first end and a second end, an outer wall, a first opening at the first end, a second opening at a second end, and a duct extending from the first opening to the second opening. A mating structure is formed from the outer wall and threads and a groove are formed in the duct.

A free-standing faucet which includes a valve assembly, a spout, an inlet tube set, and a free-standing casing tube, a spray holder, and a spray is revealed. The valve assembly consists of a housing, a mixing valve, and a diverter, and a handle. The housing is composed of a mixing valve chamber in which the mixing valve is mounted, a pipe joint connected to the inlet tube set, a connection portion formed on one side of the pipe joint close to the mixing valve chamber, a first cold water channel, and a first hot water channel. The first hot and cold water channels are formed inside the pipe joint and communicating with the connection portion and the inlet tube set. An adapter is connected to the connection portion and having second cold and hot water channels. Thereby the mixing valve can be assembled and positioned easily, securely and accurately.

A fast installation mechanism for a faucet includes a locking inner core, a fixing core, and a base. The locking inner core is a tubular member. An external thread is formed on an outer wall of the locking inner core. An upper end of the locking inner core is fixedly connected to a faucet body. A lower portion of the locking inner core is screwed into the fixing core. The base is sleeved on a lower portion of the fixing core. At least two elastic pieces on the fixing core extend out of at least two windows of the base, respectively. The installation is quick and easy, and the operation is convenient.

An easy-to-install tap structure includes a tap body, a pipe joint and a connecting pipe for communicating the tap body with the pipe joint. The connecting pipe is arranged between the tap body and the pipe joint. When the tap structure is used for a wash basin, there is no need to connect a braided hose; in the process of replacing a tap, there is no need to replace the pipe joint and the connecting pipe, so that the pipe joint and the connecting pipe can be used many times; and when the tap is dismounted, the tap body can be directly rotated, and when the tap is mounted, the connecting pipe is directly adjusted to rotate until the water outlet of the tap is arranged in the correct direction.

Provided is a coupling structure for easy installation and separation of a faucet. The coupling structure includes a connection body which is connected to a water supply pipe at one side and has a coupler at an opposite side. A connection pipe formed in the faucet is fitted to the coupler such that the faucet is coupled to the connection body to allow the faucet to be supplied with water and to discharge the water. A grab ring is formed in the coupler, and an actuation ring is installed in the connection pipe so as to be moved forward and backward. When the actuation ring is moved forward, the actuation ring expands the grab ring to allow the connection pipe to be separated from the coupler. Easy installation of the faucet enhances convenience in construction. Easy separation of the faucet, when necessary, enhances convenience in maintenance.

A fitting device for delivering mixed water, comprising a first inflow line for feeding hot water and a second inflow line for cold water, wherein the first and second inflow lines lead into a mixing chamber for mixing cold and hot water, wherein provision is made of a first shut-off device for controlling and/or for shutting off the flow from the first inflow line into the mixing chamber, wherein the first shut-off device has a temperature-sensitive element to control the flow from the first inflow line in a manner dependent on the temperature, wherein the second inflow line has an inflow to the mixing chamber that is formed independently of the first shut-off device, wherein the mixing chamber has an outlet line for the outflow of the mixed water, wherein provision is made of a temperature-setting device for setting the temperature of the mixed water.
