Abstract

A faucet assembly includes a faucet body having an upright portion defining a cartridge receiving chamber. The faucet body further has an inlet passage in fluid communication with the cartridge receiving chamber and connected fluidly to a water supply source, and an outlet passage in fluid communication with the cartridge receiving chamber. A filtering device includes a filtering cartridge that is disposed removably within the cartridge receiving chamber, and that has an outer wall surface cooperating with the upright portion to define upper and lower watertight seals therebetween, and an inner wall surface that defines a water passage chamber between the upper and lower watertight seals. The water passage chamber has upper and lower ends that are in fluid communication with the outlet and inlet passages of the cartridge receiving chamber. A spout unit is attached to the upright portion of the faucet body, and includes a spout pipe with a discharging port for release of filtered water therefrom. A valve is mounted within the faucet body. A control knob is connected operably with the valve, and is exposed outwardly to the faucet body for regulating and stopping water flow from the faucet body to the spout pipe.

Dependent claims

A faucet assembly comprising:

a faucet body including an upright portion that defines a cylindrical cartridge receiving chamber with upper and lower ends, said upper end of said upright portion having an externally threaded portion, an oblique tubular portion which extends integrally, outwardly and upwardly from a lower end portion of said upright portion, an inlet passage that is in fluid communication with said lower end of said cartridge receiving chamber and that is adapted to be connected fluidly to a water supply source, and an outlet passage that is in fluid communication with said upper end of said cartridge receiving chamber;
a filtering device including a filtering cartridge which is disposed removably within said cartridge receiving chamber and which has an outer wall surface that cooperates with said upright portion of said faucet body to define upper and lower watertight seals therebetween, and an inner wall surface that defines a water passage chamber between said upper and lower watertight seals, said water passage chamber having upper and lower ends which define respective outlet and inlet passages that are in fluid communication with said faucet body upper and lower ends, respectively;
a spout unit attached to said upright portion of said faucet body, and including a spout pipe which is in fluid communication with said outlet passage of said water passage chamber and which is formed with a discharging port for release of filtered water therefrom, said spout unit having an internally threaded lower end that engages threadedly said upper end of said upright portion of said faucet body;
a valve mounted within said oblique tubular portion of the faucet body;
and
a control knob mounted on an upper end of said oblique tubular portion of the faucet body, said control knob connected operably with said valve and exposed outwardly to said faucet body for regulating and stopping water flow from said faucet body to said spout pipe.
