Description

Technical Field

[0001] This utility model relates to the field of hair straightener technology, specifically to a hair straightener housing structure. Background Technology

[0002] The outer shell of a hair straightener typically consists of upper and lower shells, which are fixed together by a specific design to prevent the straightener from shifting during use. This design not only improves the efficiency and aesthetics of straightening but also enhances the product's durability and safety. In addition, the outer shell of the hair straightener may also include a temperature display window and button slots, allowing users to monitor and adjust the temperature of the heating element in real time, thereby ensuring ease of use and accurate temperature control.

[0003] Most existing hair straightener housings use a pivot to connect the upper and lower heating housings. When the upper and lower heating housings rotate, friction can easily occur between the upper and lower heating housings and between the heating wires. Over time, this can damage the heating wires and affect the use of the hair straightener. Therefore, we propose a hair straightener housing structure. Utility Model Content
