Claim:
An automatic cold water feed-back mechanism for a single handled faucet, including a valve housing for a valve stick, a base mount, a switching valve, a valve seat to be adapted therein; the present invention being characterized by that, a limiting valve is mounted at the upper section of the valve housing and a cold water feed-back mechanism is mutually engaged with the limiting valve thereof wherein the cold water feed-back mechanism is linked with the valve stick thereof in movement so that when the valve stick is switched off at the position of either mixed cold/hot water or hot-water discharge, the cold water feed-back mechanism will flexibly retract the valve stick thereof back to its position of cold water discharge; thus, the faucet can automatically resume its position and safely keep in the state of cold-water discharge if switched open again in use, efficiently avoiding the ignition of a hot water supplier instantaneously so as to prevent the waste of energy, and securely protecting the safety of children in the family without being scared or even scalded by hot water accidentally in practical use.
