Description

Technical Field

[0001] This utility model relates to hair styling tools, and in particular to a hair straightener. Background Technology

[0002] Most existing hair styling tools, such as curling irons, straighteners, and heated combs, consist of an operating handle and a shaping body assembled at the front end of the handle to achieve the corresponding hair styling function. Examples include the heating coil of a curling iron, the straightener of a straightener, and the comb body of a heated comb. These shaping bodies are usually integrated with the main unit, meaning one main unit can only control one shaping body. The main unit cannot be replaced with other shaping bodies, resulting in each type of shaping body requiring a separate main unit for control.

[0003] Based on the aforementioned technical deficiencies, this utility model provides a hair straightener with an adapter head structure and a main unit. The adapter head structure is detachably connected to the main unit. After the adapter head structure is separated from the main unit, it can be replaced with other shaping bodies, such as the heating roller of a curling iron or the comb body of a heated comb. Corresponding NFC chips or magnetic pieces are set on the main unit connector of these shaping bodies. In conjunction with the induction antenna or Hall effect sensor switch on the main unit, the main unit can control the temperature and airflow according to different shaping bodies.
