Description

Portable hair roll with ventilation function

The present invention relates to a portable hair roll temporarily worn on hair to form a hairstyle, and more particularly, a rotating fan and a heating element for generating electric resistance heat are mounted inside a circular pipe-shaped housing in which a plurality of exhaust ports are formed, and , By supplying power to the driving motor and heating element of the rotating fan through the battery installed inside the housing and discharging the heated air through the exhaust port, the hairstyle produced by the hair roll extends the holding time and prevents damage to the hair caused by heat. It relates to a portable hair roll having a blowing function capable of.

In general, a hair dryer or a hair iron is used to create a hair style, but a hair dryer or a hair iron instantly evaporates the moisture contained in the hair by applying high heat to lower the flexibility, thereby reducing the curl or wave of the hair. To create the desired hairstyle.

Hair styles using hair irons, etc., have the disadvantage that the duration of the finished hairstyle is very short, unlike the permanent wave, which changes the hairstyle by modifying the keratin molecular structure that makes up the hair through chemicals. The hair is rolled up on a roll of hair and fixed for a certain period of time to maintain the hairstyle.

Since the above hair roll is made by simply rolling and fixing the hair on the hair roll, the duration of the hairstyle is short compared to the wearing time, and thus, it has a disadvantage that the hair roll must be worn frequently.

In order to solve these shortcomings, Korean Patent Publication No. 10-1931996 (registered on 2018.12.18) has a power supply unit and a heater unit installed inside the portable hair roll, and heat is applied to the hair while the portable hair roll is mounted to continue the hairstyle. We are proposing a heat transfer hair roll that can improve time.

However, in the case of the heat transfer hair roll, heat generated from the heater is directly transmitted to the hair, causing hair damage, and the heated hair roll contacts the scalp or forehead, causing discomfort, and oil is secreted by the stimulation applied to the scalp. I had a problem where the oil easily got on.
