Disclosed are various embodiments providing a mechanism to couple a tub spout onto a pipe. An extension nipple adaptor can be coupled to the pipe. A compression ring can be positioned between the extension nipple adaptor and an extension nipple. The tub spout can couple to the extension nipple. A threaded screw can be screwed into the extension nipple adaptor and contact the pipe.

A crank connection structure includes a crank and a connection pipe. The crank and the connection pipe are connected in a plug-in manner and are rotatable relative to each other. A sealing ring is provided between the crank and the connection pipe. A faucet includes a body and the crank connection structure. The connection pipe is connected to the body. For the crank connection structure and the faucet using the structure, during the installation, only the angle relationship between the crank and the connection pipe needs to be adjusted, and the sealing ring is used for sealing the crank and the connection pipe without requiring raw material belt. The angles between the faucet body and the two cranks can be simultaneously adjusted to be at same level by rotating the faucet body, which abandons the traditional way of separately adjusting the cranks for leveling, achieving faster installation and adjustment.

A faucet contains: a hollow body, a control assembly, an inlet pipe set, a mixing-water outlet pipe, a pull hose, a spray head, and an isolation pipe. The hollow body includes an inflow portion and an outflow portion. The control assembly includes a mixing valve and an operation element. The inlet pipe set includes a cold-water inlet pipe and a hot-water inlet pipe. The mixing-water outlet pipe includes a first connector and a second connector. The pull hose includes an inlet segment and an outlet segment. The spray head is connected with the outlet segment of the pull hose, and the spray head is removed from and fixed on the outflow portion of the hollow body. The isolation pipe includes a channel defined therein so that the pull hose slidably moves in the isolation pipe and avoids contacting with the inlet pipe set and the mixing-water outlet pipe.

A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.

A fluid delivery device comprises a faucet. The faucet includes a hub, a sprayhead, and a hose coupling the hub to the sprayhead. Each end of the hose has a pivot coupling. One of the pivot couplings is configured to permit rotation of the hose relative to the hub. Another of the pivot couplings is configured to permit rotation of the sprayhead relative to the hose.

A waterway transferring device comprises a transferring body, a water outlet joint, and an anti-releasing mechanism. The transferring body comprises a first water inlet passage, a second water inlet passage, and a water outlet passage. The water outlet joint comprises an outer joint and an inner joint extending in the outer joint and connected to the first water inlet passage. The anti-releasing mechanism comprises a first anti-releasing member and a second anti-releasing member. When the outer joint is rotated to be connected to the water outlet passage, the first anti-releasing member and the second anti-releasing member are rotated relative to each other to be connected together, and when the outer joint is rotated reversely, the first anti-releasing member and the second anti-releasing member abut each other in an opposite direction to inhibit a rotation of the outer joint.

A faucet spout mounting system including a faucet spout tube, an inner adapter, and a bushing. The bushing is positioned radially intermediate the outer spout tube and the inner adapter. The inner adapter and the bushing engage to push flexible arms on the bushing against the outer spout tube, thus holding the bushing in place and compensating for tolerances in the spout mounting system.

A pressure hose (1) for a water-carrying system is shown and described, especially for connecting sanitary taps or for connecting parts of the water-carrying system, having a corrugated inner hose (2) made of plastic, wherein at least one hose end (3, 5) of the pressure hose (1) is provided with a connecting piece (4, 6), designed such that it differs from the inner hose (2), for joining the pressure hose (1) to a complementarily designed connecting piece of a sanitary tap and/or a part of the water-carrying system. According to the invention, it is provided that the inner hose (2) and the connecting piece (4, 6) are formed as one piece and the inner hose (2) and the connecting piece (4, 6) are preferably produced via extrusion in a common extrusion process.

An adjustable fluidic coupling includes a fluid channel extending between an upstream fluid inlet and a downstream fluid outlet. An inlet part includes a first conduit extending therethrough between the inlet at an upstream end and a first connection port at a downstream end portion. An outlet part includes a second conduit extending therethrough between the outlet at a downstream end and a second connection port at an upstream end portion. The coupling further includes a compression member selectively movable between a first position and a second position. The fluid inlet includes a threaded portion for torqued threaded connection of the inlet to a threaded end of the wall outlet, and an inlet seal fluidly sealing the inlet port to the wall outlet.

The present invention relates to a filtration system (1) having the faucet (20). 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).
