Abstract: A faucet is capable of supplying electrolytic water. The faucet comprises a cold water supply tube for supplying unprocessed water; a hot water supply tube; a water mixing valve for mixing cold and hot waters from the cold water supply tube and hot water supply tube; a faucet body connected to the water mixing valve; a clean water control valve installed in the faucet body from a valve groove; a valve groove in the faucet body and having an inner water guide channel which is communicable to a water supply channel below the faucet body; a water supply opening is communicated to a lateral side of the valve groove so as to guide water to a water electrolyzing machine. The unprocessed water flows to a water filer for filtering; then to the clean water control valve; and then to the water electrolyzing machine to get acid water or alkaline water.
