A brush for delivering at least one of an application of light and/or heat includes a handle and a head extending therefrom, a light emitting device and/or heating element and a plurality of hollow bristles extending from a surface of the head and receiving at least a portion of light and/or heated air or non-heated air through the bristles.

Provided is a hair dryer comprising: a cylindrical head housing; a heater module located inside the head housing; and a substrate module located in the rear direction of the heater module. The heater module comprises: a first heater case in a cylindrical shape; a plurality of first separators coupled to the outer peripheral surface of the first heater case at predetermined intervals; a first heating wire wound around the plurality of first separators; a plurality of second separators located between the plurality of first separators and coupled to the first heater case; and a second heating wire coupled to the first separators and the second separators.

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.

The present invention relates to an applicator head for applying liquid from a liquid supply container to a user's skin. The applicator head includes a cover, a base, a main body, and a roller. The base has a connecting sleeve with a connecting hole for communication with the container. The main body is rotatably connected to the base and defines a liquid supply channel extending to a mounting groove. A liquid supply tube delivers liquid to the groove, where the roller is rotatably mounted to apply the liquid. Rotation of the main body relative to the base alternately establishes or blocks fluid communication, thereby preventing leakage when not in use. A sealing gasket and stepped retention surfaces provide reliable sealing and secure assembly. The main body further integrates a circuit board, power supply, and phototherapy lamp with light-emitting elements, enabling combined liquid application and light therapy treatment.
