Description

Technical Field

[0001] The utility model relates to the technical field of hair curlers, in particular to a hair curler with adjustable diameter. Background Art

[0002] A curling iron is a handheld electronic product used to curl hair. Its main components are a handle and a heating roller. The curling iron is designed with a circuit panel to control the temperature. The heating roller is made of a tourmaline ceramic panel, which can evenly disperse heat, circulate heating, improve the protein structure of the hair to create a bend, and protect the hair during the curling process.

[0003] For example, in the Chinese utility model CN205321555U, a hair curler with a variable diameter is disclosed. The handle is connected to the curling assembly by a slot and a fixed base. The curling roller comprises a fixed roller element, a movable roller element, a central axis and an auxiliary roller element. The fixed roller element and the movable roller element are respectively arranged at the lower and upper parts of the curling roller in the radial direction. The movable roller element and the auxiliary roller element penetrate the fixed base and are rotatably connected to a rotating piece. A knob cap is provided on the front end of the curling roller, and the knob cap is connected to the rotating piece at this end by mortise and tenon joints. When the knob cap is twisted, the rotating piece connected to the rotating cap drives the rotating piece at the other end of the curling assembly to rotate through the central axis. The rotation of the two rotating pieces drives the roller element to rotate and drives the auxiliary roller element to move, thereby adjusting the diameter of the curling roller.

[0004] However, during the actual research and development process, the inventors found that the problem with this type of hair curling iron with a variable diameter is that when adjusting the diameter, the user is often required to hold the handle with one hand and then use the other hand to act on the knob cap to adjust it. It is impossible to achieve one-handed operation, which makes it inconvenient for the user to adjust the diameter when using it.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content
