Abstract: This invention is related to an easily operated and water-saving hand basin faucet, mainly using a freely movable element of a valve head in a valve seat to control the water volume and faucet on/off state. The valve head is controlled by a push rod to allow movement. Besides the movement of the valve head, the push rod is also featured to allow advanced decompression. When the push rod is pushed upwards, a gasket engaging over the push rod disengages from an inclined annular face on the top of the valve head peak, enabling the hydraulic pressure to be discharged from an aperture in the valve head prior to pushing the push rod, subjecting an urging portion urges against the valve head so as to jack-up the valve head easily. The hook ring on the valve head engages a stop ring on a water seal ring, such that water is able to flow through an aperture on the hook ring. As such, this invention may be easily operated in a sanitary manner, produced in a lower cost with simple assembling procedures.
