Heating apparatus for heating hair curlers

A heating apparatus for heating hair curlers being disposed in a housing and clamped by at least one hair clip;

• the heating apparatus comprising:
• a base including two assembling portions at two opposite ends thereof, at a bottom of each of the assembling portions being formed an elastic portion which is provided at an end thereof with an engaging block, a direction extending between the two ends of the base being defined as X;
• two assembling members engaged in the assembling portions of the base and each including a board which is provided along the direction X with an inner surface and an outer surface, the inner surface of each of the boards being provided along the direction X with two T-shaped engaging cavities, an engaging hole between the engaging cavities, and two positioning protrusions, the boards of the two assembling members are engaged in the assembling portions of the base with their inner surfaces opposed to each other in such a manner that the engaging blocks of the elastic portions of the base are engaged in the engaging holes of the assembling members;
• two thermal conductive members, each of which being provided along the direction X with an assembling surface and a thermal conductive surface which is arc-shaped to fit the shape of the hair clip, the assembling surface being formed with a receiving groove, along an outer edge of the receiving groove being formed two engaging ribs extending in the direction X, along a bottom of the receiving groove being formed a locking rib with a T-shaped cross section, the thermal conductive members are disposed between the two assembling members with their assembling surfaces opposed to each other, and both ends of the locking ribs of the thermal conductive members are engaged in the engaging cavities of the two assembling members;
• two heating members disposed in the receiving grooves of the two thermal conductive members and electrically connected to a control circuit disposed in the housing;
• two elastic pieces each provided with two opposed elastic edges extending in the direction X and an elastic abutting portion between the two elastic edges, the elastic pieces being disposed in the receiving grooves of the thermal conductive members in such a manner that the elastic edges are engaged with the engaging ribs of the thermal conductive members, and the heating members are pressed into the receiving grooves of the thermal conductive members by the elastic abutting portions of the elastic pieces;
• and
• a cover provided at two ends thereof in the direction X with two positioning portions, and an arc-shaped rest portion being formed between the positioning portions to fit the hair clip, the positioning portions of the cover being assembled to the two assembling members in such a manner that each of the positioning portions is provided with two positioning cavities for engaging with the two positioning protrusions of each of the assembling members, and the rest portion is rested against positioning walls of the two thermal conductive members, the rest portion and the thermal conductive surfaces of the thermal conductive members define a structure to fit the shape of the hair clip;
• when in use, the hair clip is clamped on the cover and the two thermal conductive members, and two thermal conductive layers inside the hair clip are pushed against the thermal conductive surfaces of the two thermal conductive members, the control circuit controls the two heating members to heat the conductive layers.
