Hair curler

Abstract

A hair curler comprises: a lower clamp body, comprising a heating seat for curling hair and a pair of grooves disposed at opposite sides of the heating sea; an upper clamp body, movably connected to the lower clamp body, the upper clamp body comprising an opening corresponding to the heating seat and protrusions disposed at opposite sides of the opening, the protrusions being aligned with the grooves respectively when the upper clamp body is closed to the lower clamp body; wherein the lower clamp body comprises a impeller for generating an airflow, and each groove comprises a bottom which defines vent holes to allow the airflow to enter the groove. While curling hair by the hair curler, air is accelerated by the impeller, and the accelerated air flows to the grooves via vent holes, timely cooling and protecting the hair, thereby enabling the hair to be quickly styled.
