Abstract: An improved hot-cold inlet pipe structure includes an external-threaded pipe and an internal pipe forming an integrated piping structure. The internal pipe extends outwardly a wrapping section that covers a plurality of threaded openings of the external pipe. The internal pipe is composed of non-toxic materials that include plastic materials that are high resistance to pressure and climate change. The internal pipe also reduces the use of metallic materials and does not release of toxic chemical to water stream. A depressed section of the interior of a top of end of the inlet pipe includes a receiving chamber, the receiving chamber includes an opening that includes numerous slots. The slots receive a control valve unit such that the slots mesh with the control valve unit. This design is also beneficial in the manufacturing of the inlet pipe.

Abstract: A faucet includes a faucet body, a bent tube mounted on the faucet body, a water outlet pipe retractably mounted in the bent tube and having a connector, an elastic sleeve mounted in the distal end of the bent tube, a first magnetic member mounted in the elastic sleeve, a locking sleeve mounted on the connector of the water outlet pipe and inserted into the elastic sleeve, a second magnetic member mounted in the locking sleeve and movable to approach the first magnetic member, and a spout locked onto the locking sleeve. Thus, when the locking sleeve is inserted into the elastic sleeve, the second magnetic member is attracted magnetically by the first magnetic member so as to position the locking sleeve in the elastic sleeve and to position the spout onto the distal end of the bent tube.

Abstract: An improved faucet structure includes an inlet pipe having a main metallic pipe and a non-toxic pressure and climate resistant plastic holding chamber that can be interchangeably used by multiple products. The main metallic pipe includes a ring groove with a larger diameter as a limiting element on the side thereof. The ring groove includes one or more holes thereon to further couple with even a larger diameter item. The holding chamber includes a connecting pipe disposed at a bottom end of thereof. The chamber includes two or more external leakage rings, and the rings are closely coupled to the internal wall of the main metallic pipe. This assembly reduces the needs of relying all metallic pipes, and the holding chamber is capable connecting to other faucet assemblies.

Abstract: A connecting tube structure comprises a connecting tube, screw nuts, check valves, and a rotary water-sealing device wherein the connecting tube has a stop plate at one end to mount to a grooved seat of the rotary-sealing device and a cavity at the other end for the accommodation of one check valve with a movable plug supported by a spring to shut off water discharge from the faucet and prevent the return of dirty water. The rotary water-sealing device, having watertight O-rings adapted to the upper section and a V-shaped expanding side wall extending at the lower section, is sealed to the bottom and internal surface of the shower head and enclosed by the screw nut secured to the shower head, providing high-and-lower pressure water-sealing benefit as well as rotation in 360 degrees to prevent the connecting tube from getting twisted up and hindering the smooth transport of water supply.
