Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of hairdressing appliances, in particular to an electric heating comb. Background Art

[0002] A conventional electric comb mainly includes a housing, a heating element disposed in the housing, and a plurality of heat-conducting comb teeth protruding from the outer side of the housing and connected to the heating element at the inner end. The heat-conducting comb teeth receive the heat from the heating element and heat up, thereby heating and caring for the hair.

[0003] In order to improve the safety of use, some existing electric heating combs will also add an anti-scalding sleeve on the outside of the thermally conductive comb teeth to prevent users from being burned by the thermally conductive comb teeth. The anti-scalding sleeve also includes: a base plate and a plurality of tooth sleeves that protrude from the base plate and are correspondingly sleeved on the outside of each thermally conductive comb tooth. The inner hole of the tooth sleeve passes through the base plate to allow each thermally conductive comb tooth to be inserted into the tooth sleeve. In order to facilitate the sleeve mounting and positioning of each tooth sleeve on the outside of the corresponding thermally conductive comb tooth, positioning grooves are also provided on the opposite sides of the thermally conductive comb tooth, and the inner hole wall of the tooth sleeve is correspondingly provided with relatively protruding positioning ribs. During assembly, the positioning ribs on the inner hole wall of the tooth sleeve are inserted into the positioning grooves of the thermally conductive comb teeth.

[0004] However, the inventors discovered during the specific implementation that the existing assembly positioning structure utilizing the positioning grooves on the heat-conducting comb teeth to cooperate with the positioning ribs on the tooth sleeve makes the forming and processing of the heat-conducting comb teeth relatively difficult. Moreover, during assembly, the positioning grooves on both sides of the heat-conducting comb teeth and the positioning ribs on each tooth sleeve are also difficult to quickly and accurately align, which is not conducive to the rapid assembly of the anti-scalding cover.
