Abstract: A hair curling device includes an elongated heating member, a handle member, a powering arrangement including a motorized unit supported in said handle member, and a clamping arm pivotally moved between an opened position that the clamping arm is tilted from the heating member and a closed position that the clamping arm is in contact with a heating surface of the heating member. The clamping arm is driven to rotate around an axis of the heating member by the motorized unit, such that after the clamping arm is moved at the closed position for retaining a lock of hair between the clamping arm and the heating surface of the heating member, the clamping arm is automatically rotated for guiding the lock of hair being whirled around the heating member.

Abstract: A hair curling device includes a handle member, a heating member, a PPS made connector, and a clamping arm rotatable around the heating member in 360°. A rotatable hub unit, which is made of nylon with 30% of fiberglass, coupled at the connector. An operation unit, which is made of nylon with 30% of fiberglass, includes an operation button, a rotatable clamping arm, and a button cap. The PPS made connector and the nylon made operation unit substantially reduce the heat transmitted to the handle member. A power operating arrangement is incorporated with the connector to rotate the clamping arm about the heating member at two opposite directions. When the clamping arm is rotated about the heating member, the clamping arm guides and whirls the lock of hair around the heating member neatly.
