| 20120097279 | FAUCET STRUCTURE - 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. | 04-26-2012 |

| 20110209793 | HOT-COLD INLET PIPE STRUCTURE - 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. | 09-01-2011 |
