Hair Curling Device

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.

What is claimed is: 
     
         1 . A hair curling device, comprising a handle member, a heating member, a connector, a rotatable hub unit, an operation button, and a rotatable clamping arm, wherein said connector, which is made of PPS, connects said handle member with said heating member, wherein said rotatable hub unit comprises two rotatable hubs coupled at upper and lower portions of said connector to enclose said connector, wherein said operation button and said rotatable clamping arm are coupled at an outer surface of said rotatable hub unit via a button cap, wherein said clamping arm is rotatable around said heating member in 360°, wherein said rotatable hubs, said operation button, and said button cap are made of plastic. 
     
     
         2 . The hair curling device, as recited in  claim 1 , wherein said clamping arm is coupled to said rotatable hub unit via said operation button and is coupled to said connector via said rotatable hub unit. 
     
     
         3 . A hair curling device, comprising a handle member, a heating member extended from said handle member, a clamping arm extended along said heating member, an operation button operatively control said clamping arm, and a power operating arrangement which comprises an electric motor supported in said handle member, a two-directional-control operation button operatively controlling said element motor, a gear assembly operatively coupled with said electric motor, and a rotatable hub unit, wherein said rotatable hub unit is driven to rotate by said electric motor through said gear assembly and is coupled to said clamping arm in such a manner that when said two-directional-control operation button is actuated to activate said electric motor, said rotatable hub unit is driven to rotate so as to selectively drive said clamping arm to rotate around said heating member at one of clockwise direction and counter clockwise direction. 
     
     
         4 . The hair curling device, as recited in  claim 3 , wherein said rotatable hub unit is driven to rotate by said electric motor through said gear assembly such that said rotatable hub and said clamping arm are rotated around said heating member at 360°, wherein said clamping arm is rotated around said heating member for whirling a lock of hair around said heating member after the lock of hair is grasped between said clamping arm and said heating member.
