Abstract

A hand-held multi-function heating device includes a body receiving a power connection member and a battery. A power connector is mounted to the power connection member and includes first and second electrodes electrically connected to first and second electrodes of the power connection member respectively. An insulating tube is mounted on an end of the power connector. The insulating tube includes a first end and a second end. The second end of the insulating tube extends away from the power connection member. A first end of a heating coil is electrically connected to the first electrode of the power connector. The heating coil extends through the insulating tube and has a second end located outside of the insulating tube. The heating coil includes a coiled portion forming a heating section. The second end of the heating coil is electrically connected to the second electrode of the power connector.
