ABSTRACT:
A foot-controlled water faucet for regulating the outflow of water from a water faucet by means of air pressure comprises a compressing bladder connected with an air bladder in the water faucet by a passageway, a valve block, a ring body and a knob associated in proper order to form the water faucet. When stepping on the compressing bladder by foot the air inside is compressed and is squeezed to the air bladder in the water faucet via the passageway. The air bladder expands and pushes the platform as well as the stem in the ring body and the valve block respectively downward. The stem moves away from the opening of the valve block and water flows out. Water is stopped by releasing the compressing bladder which sucks back the air from the air bladder that is then contracts and allows the stem to move back to the original position. It can also be controlled by hand as an ordinary water faucet.
