Problems solved by technology

[0002] Existing faucet casings are made of metal or plastic. Metal materials generally contain lead. When the metal surface of the faucet casing is corroded by water, the lead will come into contact with water, which is not environmentally friendly and endangers people's health. At the same time, Metal faucet shells have low production efficiency, high cost, and low yield; plastic faucet shells have poor strength, poor quality, and short service life

Abstract

The invention discloses a faucet shell produced through secondary injection molding. The faucet shell comprises a main body, wherein the main body comprises an outer plastic part and an inner plastic part, the inner plastic part is covered with the outer plastic part, and the outer plastic part is provided with an electroplated surface layer; the inner plastic part is provided with a valve core cavity body, a bottom cavity body, a water channel cavity body and a bubbler connecting hole, an opening is formed in one side of the water channel cavity body, a water channel seal plate is arranged at the opening, and an annular seal ultrasonic welding wire is arranged on the inner side surface of the water channel seal plate; an oblique through hole allowing a drainer draw bar to penetrate is formed in the rear side of the bottom cavity body; a cold / hot water inlet hole is formed in the bottom of the valve core cavity body. Compared with the prior art, the faucet shell has the advantages of being environmentally friendly, lead-free, high in production efficiency, high in rate of finished products, low in cost and convenient to mount.

Description

technical field [0001] The invention relates to a faucet fitting, in particular to a secondary injection molded faucet shell. Background technique [0002] Existing faucet casings are made of metal or plastic. Metal materials generally contain lead. When the metal surface of the faucet casing is corroded by water, the lead will come into contact with water, which is not environmentally friendly and endangers people's health. At the same time, Metal faucet housings have low production efficiency, high cost, and low yield; plastic faucet housings have poor strength, poor quality, and short service life. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of the prior art, the present invention provides a secondary injection molded faucet housing. [0004] The above object of the present invention is achieved through the following technical solutions: a secondary injection molded faucet housing, including a main body, characterized in that: ...
