Abstract

A stainless steel faucet to achieve the hygienic purpose by not creating potential difference or developing rust is made in one-piece of a cock shape by precision cast process, including one end of the body of the faucet being threaded to be engaged into the water pipe; a spout on the other end of the body of the faucet; a bolting hole to allow a cartridge to be fastened to the spout; a ceramic gate valve at the bottom of the cartridge to control the on and off of the water; and a handle is bolted to the top end of the cartridge to control the operation of the ceramic gate valve of the cartridge.

Description

BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention is related to a stainless steel faucet, and more particularly to a precision cast stainless steel one-piece faucet that presents no potential difference, rust and toxic substance.

(b) Description of the Prior Art

Modern technology brings many benefits to the life of the mankind, but it also is polluting our environment. Many diseases resulted from modern civilization are threatening our lives, and the cancer has been the most popular and reported with the highest mortality. Among many causes leading to cancer, the most direct cause happens to be the source of potable water. Water we drink is fetched from the source in the mountain through the reservoir, and delivered to the faucet in the house via water pipes. Most of the water pipes are usually cast from pig iron or copper. Water contacting the pig iron or copper will develop chemical reaction to affect the water quality, resulting in formation of toxic patina, in case of copper pipe; or of Chromium, the heavy metal, in case of plated copper pipe. The plating process also presents the problem of polluting the environment to endanger our next generations by producing toxic or carcinogenic substances. Potential difference is created when the material of the faucet is different from that of the water pipe that facilitates the production of rust and/or toxic substances. So far, stainless steel is considered as the most hygienic material in the field of modern technology since when the stainless steel contacts the water; it will not produce toxic substance from the chemical reaction. Therefore, stainless steel is used today for the water pipe. If the faucet is not made of the stainless steel, potential difference will be created when the faucet is connected to the stainless steel pipe for the faucet to get rusty or produce carcinogenic substances.

SUMMARY OF THE INVENTION

The primary purpose of the present invention is to provide a faucet that is made of stainless steel in one-piece of a cock shape by precision cast process. One end of the body of the faucet is threaded for the faucet to be engaged into the water pipe. A spout is provided on the other end of the body of the faucet. A bolting hole is provided at where appropriately in the middle section of the body of the faucet to allow a cartridge to be fastened to the spout. A ceramic gate valve is provided at the bottom of the cartridge to control the on and off of the water. A handle is bolted to the top end of the cartridge to control the operation of the ceramic gate valve of the cartridge. The stainless steel material and the ceramic gate valve will not create potential difference or develop rust as the water pipe is also made of stainless material to achieve the hygienic purpose.

The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

Many other advantages and features of the present invention will become manifest to those versed in the art upon making reference to the detailed description and the accompanying sheets of drawings in which a preferred structural embodiment incorporating the principles of the present invention is shown by way of illustrative example.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims. [0012]
Referring to FIGS. 1 through 4, an improved structure of a faucet of the present invention is essentially comprised of a body ([0013] 11) in a cock shape, made of stainless steel in one piece by precision cast process; having a threaded end (12) for the faucet (1) to be engaged into a water pipe (2) and having another end provided with a spout (13); a bolting hole (14) is provided at where appropriately in the middle section of the body (11) to be engaged with a cartridge (15); a ceramic gate valve is provided at the bottom of the cartridge (15) to control on and off of the water; and a handle (17) is bolted to the top of the cartridge (15) to control the ceramic gate valve of the cartridge (15) characterized by that the faucet (1) is made of the same material as that of the water pipe (2) so that both will not create potential difference or develop rust to achieve the hygienic purpose.
The present invention by offering a stainless steel faucet that will not create potential difference with the water pipe achieves its hygienic purpose. Therefore, this application for a utility patent is duly filed accordingly. [0014]
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above. [0015]
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention. [0016]

Claims

I claim:

1. A faucet made of stainless steel in one-piece of a cock shape by precision cast process characterized by that one end of the body of the faucet being threaded for the faucet to be engaged into the water pipe; a spout being provided on the other end of the body of the faucet; a bolting hole being provided at where appropriately in the middle section of the body of the faucet to allow a cartridge to be fastened to the spout; a ceramic gate valve being provided at the bottom of the cartridge to control the on and off of the water; and a handle is bolted to the top end of the cartridge to control the operation of the ceramic gate valve of the cartridge; to achieve the hygienic purpose by not creating potential difference or developing rust.
