ABSTRACT:
A fluid faucet includes a first passage having a first mouth and connected to a first fluid source, a second passage having a second mouth and connected to a second fluid source, a hollow cylinder having a first hole and a second hole, a third passage having a third mouth for passing a fluid mixed from the first and second fluids, an electromagnetic valve having a valve stem engagable with the third mouth and an infrared coupling-and-controlling circuit. The first and second holes are capable of respectively fully shielding or communicating with the first and second mouths when the hollow cylinder is rotated. The infrared coupling-and-controlling circuit actuates the electromagnetic valve to set the valve stem to be in disengagement with the third mouth to permit the mixed fluid passing through the third mouth when a body is in a distance close enough to such a faucet.
