ABSTRACT: A faucet for automatic water supply and stoppage, comprising a casing having fastened therein a battery- operated two-way electromagnetic valve controlled by an infrared controller to control a water flow control assembly to stop or open a water outlet passage. The water flow control assembly comprises a movable stopper to releasably block up the water outlet passage, an elastic element disposed above the movable stopper, covered with a cover plate, and defining with the cover plate a water chamber. The cover plate has an outlet hole at the top, which is controlled to open or close by the mandrel of the electromagnetic valve and disposed in communication with the water outlet passage, and an inlet hole which is disposed in communication with the water chamber. The movable stopper defines therein a channel having one end disposed in communication with the water inlet passage and an opposite end disposed in communication with said water chamber through a through-hole made in size relatively smaller than the inlet hole of the cover plate. The infrared controller is sensed to trigger the electromagnetic valve to lift the mandrel from the outlet hole, permitting the movable stopper to be pushed toward the water chamber by intake water pressure so as to fully open the water outlet passage. 11
