Description

Technical Field

[0001] This utility model relates to the field of hair styling tools, and in particular to a hair styling tool with a replaceable electric heating styling head. Background Technology

[0002] Electric hair styling tools are common everyday styling tools, including straighteners, curling irons, and heated combs. Traditional hair styling tools use a one-piece structure where the heating element and handle are fixedly connected. Users need to purchase multiple devices to meet different styling needs, leading to inconvenient storage and increased operating costs. To improve ease of use, modular hair styling tools are gradually emerging, achieving multi-functional integration through detachable connections between the handle and the heated styling head.

[0003] However, existing interchangeable-head hair styling tools generally only have basic heating functions. When users need cool air styling, they must use an additional cool air device, interrupting the operation and creating a fragmented experience. Although a few high-end all-in-one hair styling tools have attempted to integrate cool air functionality, their fixed structure cannot be adapted to the interchangeable-head architecture. Therefore, it is necessary to develop a hair styling tool that combines modular interchangeable-head functionality with efficient cool air styling capabilities. Utility Model Content
