Composite Faucet Structure Made of Plastic and Metal Materials

Abstract

A composite faucet structure made of plastic and metal materials contains: a body, at least one inlet pipe, at least one positioning element, and at least one control valve. The body is injection molded from plastic material and includes at least one water chamber, each of the at least one inlet pipe is made of metal material and includes a connection portion having a groove. The at least one positioning element is retained in the groove of the connection portion of each inlet pipe, and each of the at least one control valve is fitted in the at least one water chamber of the body and includes an abutting face defined on a bottom of each control valve and contacting with an O ring, hence the connection portion of each inlet pipe contacts with the O ring of the abutting face of each control valve.

What is claimed is: 
     
         1 . A composite faucet structure made of plastic and metal materials comprising:
 a body injection molded from plastic material, and the body including at least one water chamber;   at least one inlet pipe made of metal material, each of the at least one inlet pipe including a connection portion formed on one end of each inlet pipe, and the connection portion having a groove defined on an outer rim of the connection portion;   at least one positioning element retained in the groove of the connection portion of each inlet pipe; and   at least one control valve fitted in the at least one water chamber of the body, and each of the least one control valve including an abutting face defined on a bottom of each control valve and contacting with an O ring, hence the connection portion of each inlet pipe contacts with the O ring of the abutting face of each control valve;   wherein the connection portion of each inlet pipe is covered in the body with each positioning element as injection molding the body so as to increase contact area of each inlet pipe and the body.   
     
     
         2 . The composite faucet structure as claimed in  claim 1 , wherein the body further includes at least one square tab arranged on a bottom of at least one controlling seat thereof individually, and the connection portion of each inlet pipe is covered in each of at least one square tab of the body with each positioning element as injection molding the body. 
     
     
         3 . The composite faucet structure as claimed in  claim 1 , wherein the groove of each inlet pipe has two opposite locking parts arranged on an outer rim of the connection portion of each inlet pipe, and each positioning element includes two opposite retaining portions which retain in the two opposite locking parts of each inlet pipe. 
     
     
         4 . The composite faucet structure as claimed in  claim 1 , wherein each positioning element is a U-shaped sheet. 
     
     
         5 . The composite faucet structure as claimed in  claim 3 , wherein each positioning element is a U-shaped sheet. 
     
     
         6 . The composite faucet structure as claimed in  claim 1  further comprising a base and a cap, and the base is fitted with the bottom of the body, and the cap covers the base so as to shield the body in the cap. 
     
     
         7 . The composite faucet structure as claimed in  claim 6 , wherein the base includes two first through holes configured to accommodate the at least one inlet pipe respectively, and the cap includes two second through holes configured to extend out of upper ends of the at least one controlling seat of the body individually.
