Abstract: A drinking water faucet capable of discharging waste water includes a main body, a valve base, a water control unit, a connecting tube and a securing nut. A receiving space that is through and downward is formed inside the main body, and a trough room and an air hole are formed at front portion of the receiving space, upper portion of which has a water outlet tube. A water outlet hole and water inlet tube are located at upper and lower portions of the valve base respectively, and a water control space and discharging portion are formed at front portion of the valve base. The reflux of waste water can be prevented to contaminate the filtering components by using the combination of the air hole, the discharging portion, a waste water import tube and a waste water export tube, so the drinking water becomes more clean and safe to drink.

Abstract: A unidirectional ceramic control valve includes a valve shell, a shaft, a ring unit, an upper ceramic piece, a lower ceramic piece, a valve base and at least one anti-leak ring. Lower section of the valve shell has two hook holes, and two notches are formed therebelow. A receiving trough is formed at an inner portion of lower section of the shaft to provide a space for the ring unit and the upper ceramic piece. The ring unit is a ring-shaped body with low friction coefficient, and when the ring unit is disposed between the shaft and upper ceramic piece, it prevents the shaft from directly contacting the upper ceramic piece to generate wear. The upper ceramic piece has two symmetric water holes, while the lower ceramic piece has two symmetric circulating holes. A first protruding unit and a second protruding unit are correspondingly formed at the valve base.
