Inner water pipe assembly for faucet

摘要

An inner water pipe assembly for faucet includes a copper shell with a longitudinal channel and a lateral channel. A valve seat is mounted in the longitudinal channel, and includes an inlet channel, an outlet channel, and a seat hole formed there through. A valve sleeve is fitted into the lateral channel, and has an inlet notch communicating with the inlet channel, a chamber inside the valve seat and an annular inlet passage formed between the valve sleeve and a valve. The valve is fitted into the pipe sleeve for water passage control. A valve chamber inside the valve communicates with the outlet channel of the valve seat and a water inlet formed through a periphery of the valve. The inner water pipe assembly provides a rational design reducing the copper material and cost in production, simplifying the manufacture, and resolving excessive heavy metal in drinking water.

主权项

1. An inner water pipe assembly for faucet comprising:
a shell having: a longitudinal channel defined inside the shell in a longitudinal direction; a lateral channel defined inside the shell in a lateral direction and having an outer opening; and a rotary portion connected with the outer opening of the lateral channel; a valve seat mounted inside the longitudinal channel of the shell, and having: an inlet channel; an outlet channel; and a valve-mounting hole formed through a peripheral wall of the valve seat and communicating with the inlet channel and the outlet channel; a valve sleeve having: a first end fitted into the lateral channel; a second end; and an inlet notch formed through a portion of the second end of the valve sleeve to communicate with the inlet channel of the valve seat and a chamber defined inside the valve sleeve; a valve fitted into the valve sleeve, controlling water to pass or not to pass through the valve, and having: a valve chamber defined inside the valve and communicating with the outlet channel of the valve seat; and a water inlet formed through the peripheral wall of the valve, and communicating with the valve chamber; and an annular inlet passage formed between a peripheral wall of the valve and an inner wall of the valve sleeve and communicating with the outlet channel of the valve seat and the water inlet of the valve.
