The heat conducting clamping bin 6 is arranged so as to separate water flow from the electric heating tube 11, and guide the water flow to circulate through a gap between the valve body 1 and the heat conducting clamping bin 6, so that the water flow and the electric heating tube 11 are not in direct contact, compared with the existing instant heating type electric heating faucet, the phenomenon of electric leakage caused by water corrosion of an insulating sealing layer is avoided, and the safety and the reliability are higher.

In the technical scheme, the outside of the heat conduction clamping bin 6 is of a conical structure with a small upper part and a large lower part, and an insulating liquid medium with good heat conduction performance is filled in a cavity formed by the heat conduction clamping bin and the electric heating tube 11.
