Faucet having extendable aerator

Abstract

A faucet includes an aerator including a projection; a coupling member including a protrusion, a cavity engaging the projection, and a stud; a spout including a well for receiving the protrusion, and an aperture for receiving the stud; a mounting component releasably secured to the spout and including a side extension, a thermostatic mixing valve in the side extension, a fastening member secured to the thermostatic mixing valve, and a handle releasably secured to the fastening member; a hot and cold water passages pipe in the mounting component and including an outlet passage and two inlet passages all in fluid communication with the thermostatic mixing valve; a tube member having one end in fluid communication with the outlet passage; and a spout tube having one end in fluid communication with the other end of the tube member and the other end in fluid communication with the aerator.

What is claimed is: 
     
         1 . A faucet comprising:
 an aerator comprising a projection;   a hollow coupling member comprising a protrusion at one end, a cavity for complimentarily engaging the projection, and a stud distal both the protrusion and the cavity;   a spout comprising a well at one end for complimentarily receiving the protrusion, and an aperture for complimentarily releasably receiving the stud;   a hollow mounting component releasably secured to the other end of the spout and comprising a hollow side extension, a thermostatic mixing valve disposed in the side extension, a fastening member secured to the thermostatic mixing valve, and a handle releasably secured to the fastening member for controlling the thermostatic mixing valve;   a hot and cold water passages pipe partially disposed in the mounting component by securing to the side extension of the mounting component, the hot and cold water passages pipe being further releasably secured to a deck and comprising an outlet passage in fluid communication with the thermostatic mixing valve, and two inlet passages each in fluid communication with the thermostatic mixing valve;   a cold water tube connected to one of the inlet passages;   a hot water tube connected to the other inlet passage;   a tube member having one end in fluid communication with the outlet passage;   a check valve disposed in the other end of the tube member; and   a spout tube having one end in fluid communication with the other end of the tube member and the other end in fluid communication with the aerator by passing the hot and cold water passages pipe and passing through both the mounting component and the spout;   wherein both hot water flows through the hot water tube and cold water flows through the cold water tube to arrive at the thermostatic mixing valve for blending prior to flowing to the aerator via the outlet passage, the tube member, the check valve, and the spout tube.
