Abstract

An environmental faucet includes a body, a valve seat, a valve core, an outlet elbow, a water-intake duct, an aerator, a locking cap and a handle. The valve seat and the valve core are mounted in the body. The outlet elbow is connected with a top end of the valve seat and has an outer pipe and an inner pipe, the outer pipe is made from metal, and the inner pipe is made from plastic. The water-intake duct is connected with a bottom end of the valve seat and has an outer pipe and an inner pipe, the outer pipe thereof is made from metal, and the inner pipe is made from plastic. As water entering the environmental faucet in a flow path sequentially through the water-intake duct and the outlet elbow does not flow through the metal portions, excessive heavy metal released in the water can be avoided.

First claim

What is claimed is:

1 . An environmental faucet, comprising:
a body being cylindrical in shape and having:
a top end;
a bottom end; and
a tube seat formed on and extending perpendicularly outwards from a sidewall of the body and being internally threaded;
a valve seat mounted in the body and having:
a top end being externally threaded;
a bottom end being internally threaded;
a connected recess formed in a peripheral wall of the valve seat;
a valve core having a spindle formed on and extending from an outer portion of the valve core, wherein an inner portion of the valve core is mounted inside the connected recess of the valve seat, and one end of the valve core opposite to the spindle is mounted in the tube seat of the body; an outlet elbow having:
an outer pipe made from a metal material; and
an inner pipe made from a plastic material and mounted inside the outer pipe, wherein
an inlet end of the outlet elbow engages the top end of the valve seat; a water-intake duct having:
an outer pipe made from a metal material; and
an inner pipe made from a plastic material;
wherein a top end of the water-intake duct is securely mounted in the bottom end of the valve seat; a locking cap having:
a central coupling hole; and
a locking section being externally threaded, formed on a periphery of the locking cap, and engaging an internally-threaded portion of the tube seat of the body; and
a handle securely connected with the locking cap and the valve core, wherein the spindle of the valve core is mounted in the handle through the central coupling hole of the locking cap.

2 . The environmental faucet as claimed in claim 1 , wherein an aerator is made from a plastic material and is mounted on an outlet end of the outlet elbow.

3 . The environmental faucet as claimed in claim 1 , wherein the outlet elbow has:
a PP (Polyproplene) tube connector securely connected with bottom portions of the outer pipe and inner pipe of the outlet elbow to seal and join the bottom portions of the outer pipe and the inner pipe; and a nut mounted on the top of the connector mounted around a periphery of the outer tube and located above the PP tube connector, wherein an inlet end of the outlet elbow engages the externally threaded top end of the valve seat with the nut.

4 . The environmental faucet as claimed in claim 3 , wherein the outlet elbow has a second O-ring mounted between an outer surface of the PP tube connector and an inner surface of the valve seat to form hermetic seal between the outlet elbow and the valve seat.

5 . The environmental faucet as claimed in claim 1 , wherein the outlet elbow has a first O-ring mounted on an inlet end of the inner pipe of the outlet elbow and is mounted between the inner pipe and the outer pipe of the outlet elbow to avoid the inner pipe to come off the outer pipe.
