The invention discloses an antifreeze tap. The antifreeze tap comprises a heating wire wound on a water pipe, a control switch is connected to the heating wire, a power source is connected to the control switch, and a thermal insulted layer is wound out of the heating wire. By mounting the heating wire whose temperature can be controlled on the water pipe, the water pipe can be heated, so that the tap can resist freeze and unfrozen, meanwhile, thermal insulated materials wrap the heating wires so that ice cubes in the water pipe can be rapidly unfrozen and heat can be preserved, the heating speed is accelerated, and human are provided with convenience. In addition, the method is safe, and easy to operate, and causes no potential safety dangers.
