ABSTRACT:
A battery powered electric curling brush/iron includes an elongated cylindrical electrically heated wand detachably connected to the end of a hollow handle by a pair of separable electrical connector terminals. The handle houses rechargeable batteries for supplying electrical power to the wand through the connector terminals and a charging circuit for recharging the batteries from an external AC household source through a connector plug movable from a retracted position in the handle to an extended position projecting through an opening in a wall thereof. The opening is closed by a slidable cover having a closed position wherein the opening is covered, the batteries are disconnected from the wand and the plug is retracted; a partially open position wherein the cover operates a switch to connect the wand to the batteries and the plug is retracted; and an open position wherein the wand is again disconnected from the batteries and the plug may be manually moved to its extended position to allow recharging of the batteries through the charging circuit.
The wand is heated by a metal foil resistance heating element electrically insulated by layers of Kapton film.
