Description

Hair curler

Technical Field

The present application relates to the field of hair styling tools, and more particularly, to a curling iron.

Background

With the continuous improvement of the modern living standard, people are paying more attention to personal figures and hairstyle shaping, so that the rapid development of hair curlers is promoted in recent years, and the hair curlers are special care appliances for hair shaping and can play roles in shaping and hair care. The most common form of hair curler is a hair curler, which can be used for curling and styling hair by utilizing heat, an electric heating element is arranged in the hair curler, the hair is curled on the hair curler, the hair is heated by the electric heating element and is curled and styled, and the hair is curled after the hair is detached from the hair curler. The user can use the curler to make various curls, and the hairdresser who has the salon and the hair salon can use a set of curler tool to make various curls such as big wave curls, drooping natural curls, drooping shoulder curls, garrulous curls, ear scalding, varus curls, valgus curls, and is deeply loved by lovers.

Traditional curler all adopts the fixed curler of diameter to perming, curler can not change the size of diameter, and the fixed wave of size can only be scalded out to a curler, but curl radian when daily use curler is not fixed, and the hairstyle to the molding is different to length and every person, needs the curler of different diameter sizes to satisfy the hairstyle of different degree of curling, just so just needs to purchase and be equipped with the curler of a plurality of different diameters, is unfavorable for the convenience of use, has also increased the consumption of user simultaneously, and sometimes a hairstyle just needs different waves, and this just needs to use a plurality of curlers simultaneously to curl hair, and is very troublesome.

In order to meet the requirement of changeable hairstyles, the existing hair curler instruments on the market are provided with hair curlers/tubes with different diameters in a mode of being provided with accessories; the mode improves the manufacturing cost and the consumption and use cost to a certain extent, and reduces the convenience of storage and cleaning of the instrument. However, when the user uses the device, the user needs to replace different accessories for changing the size of the wave hairstyle, so that the convenient experience of the user is reduced; and the size of the auxiliary hair curler is fixed (such as 19mm/22mm/25mm/28mm/32 mm) and cannot be adjusted to the size required by the consumer, so that the selectivity and applicability of the consumer are reduced.
