The utility model relates to a high and cold hot dozzle with heating function, including the cap body, cap body from interior to exterior has set gradually inlayer, electrical heating layer and skin, and zone of heating detachable sets up between inlayer and skin, is provided with an intermediate layer between electrical heating layer and the inlayer, is provided with power and temperature detect switch in the intermediate layer, and power, temperature detect switch and electrical heating layer constitute the return circuit. This high and cold hot dozzle is provided with temperature detect switch in the intermediate layer, when being less than default temperature in the cap, can carry out the electrical heating through electrical heating layer, and when reaching default temperature, temperature detect switch stops electrical heating layer work, can realize automatic temperature control to can keep warm with the head that adapts under the different occasions through the temperature detect switch who changes different parameters.
