Description

Hair magic device having pressure regulating function}

The present invention relates to a pressure-controlled hair bag, and in detail, the control of the pressure control is configured to be simple and accurately controllable, and at the same time, even if a uniform pressure is applied according to the selected pressure intensity, even if an artificial force of the worker is not applied. Pressure control is possible to effectively prevent body fatigue and pain-causing phenomena, and at the same time, it is possible to increase the convenience and efficiency of work, and to maintain the selected pressure level as it is to increase the completeness of the hairstyle. will be.

In recent years, as interest in fashion and aesthetic senses has increased rapidly and each person is free to express their individuality, interest in expressing various aesthetic senses is increasing.

In particular, the interest in hairstyles is increasing exponentially because hairstyles can be directed in various ways depending on clothes and places, as well as various personalities and aesthetic senses according to styles.

Hair magic device is widely used as the most popular beauty device due to its advantage of being able to create a variety of hairstyles through a styling process such as curling or straightening hair using pressure and heat. Is being used.

In general, the hair bag is a hinge-coupled upper rod and lower rod, a heating means for generating heat, and a heating plate installed on opposite sides of each rod to receive heat from the heating means and apply pressure and heat to the hair. Consists of

Looking at the method of using such a conventional hair bag, the user (worker) arranges the hair between the heated heating plates of the hair bag, and then presses the upper rod and the lower rod with artificial force of the hand and wrist, and then the wrist. The hairstyle is produced by rotating it to give curls, or by repeatedly moving the hair bag horizontally along the length of the hair to straighten the hair.

In other words, in the conventional hair bag, pressure control, hair curling or straightening are not only made by manpower such as the user's wrists, hands, arms, etc., but also because such movements are repeatedly performed continuously, the fatigue of the body increases and causes pain. And, when the fatigue and pain of the body is continuously repeated, a problem that leads to serious body damage and illness beyond the pain occurs.

In general, the pressure strength of a hair bag varies depending on the current condition, such as the healthy degree of the hair, the degree of damage, the amount of hair, the degree of curl, and the type of styling (curl or straight). Since it is determined by the strength of the user's wrist and hand, the degree of physical fatigue further increases.

In particular, in the case of hair designers such as beauty salons and hair shops, the amount of hair styling work using such a hair bag is vast, so the fatigue and pain inducing phenomena of the body further increase. Occupational diseases are occurring uncommonly.
