Description

ELECTRIC HAIR TOOL {ELECTRIC HAIR TOOLS}

According to the present invention, when ultrasonic waves, which are the principle of air bubble generation (cavitation), are transmitted to water through the surface of metal, numerous bubbles are generated and extinguished in water, absorbing gaseous bodies in water and repeating explosions. It uses the effect of crushing and releasing the water, and the water-soluble liquid is contained in the water tank of one part of the electric hair appliance, and when the electric hair appliance is squeezed, the control valve operates at a certain pressure so that a certain amount of liquid flows out. On the other side of the electric hair instrument, the ultrasonic generator was placed in direct contact with the hair to effectively absorb the supply of water and water-soluble liquid in the hair.

In daily life, after drying the hair by using a hair dryer, the hair is dried by using the wind along with the heat. At this time, the hair is drained from the hair by heat and wind, and the hair is damaged by the lack of moisture. In addition to dry hair. In addition, the hair damage and the lack of moisture in the hair is generated by the strong heat caused by the spray perm or general perm using a hot air balloon in a general beauty salon.

In order to supply water to the hair in a conventional beauty salon, an ultrasonic humidifier is used to connect the pipe to the spray part of the ultrasonic humidifier to directly supply the sprayed moisture to the hair, but the external part of the layered hair is supplied with moisture, but the inner part of the hair There is a lot of waste of time and energy to be supplied with moisture, there was a problem that an imbalance occurs in the supply of moisture to the outside and inside of the hair.

In order to solve the above problems, the operation of the humidifier tube is made in two or three forms or rotated while maintaining a constant angle, but some convenience is provided, but the hair is supplied evenly and uniformly. There was a limit.

From this, the inventions described in the claims of the present invention were devised to effectively supply constant and even moisture to the entire hair. Looking at the structure of the hair, the cross section of the hair has three layers, the center of which is medura (water quality, medulla), the periphery of which is surrounded by the cortex (cortex) and the surface is called cuticle scales (cuticle scales), and the parental epidermis is as hard as fish scales to surround and protect the cortex.

The moisture content in normal hair is usually about 12% but due to the use of hair dryers and frequent hot air ballooning, the moisture in the hair is released and the hair causes dry hair, porous hair, damaged hair, and so on. Water must be crushed between layers of layers to supply water to hair. When ultrasonic waves, which are the principle of air bubbles (cavitation), are transferred to water through the surface of metal, numerous bubbles are generated and destroyed in the water. It is used to absorb gas body in water and to pulverize and release particles in water while repeating explosion. Ultrasonic vibrator is a crystal oscillator which applies high frequency voltage to crystal plate and resonates, and metal is magnetized. Magnetostrictive oscillators and pressure using crushing phenomenon It is used for ceramics and semiconductor devices, and the ultrasonic oscillator is fixed at the center of the metal cover which is in contact with the hair on the V-shaped end, and the thermistor whose resistance value is changed according to temperature by making a square groove at the center of the mica plate at the back of the ultrasonic transducer. After contacting, the ultrasonic vibrator maintains a constant elasticity with the body while strengthening the contact force with the metal cover by using a leaf spring or coil spring, and attaching and detaching a bucket of water behind the cover of the metal at the other end of the electric hair device. When squeezed, the liquid flows out of the water tank at a constant pressure and a hole is provided in the water tank and the metal cover which has a control valve to prevent the liquid from flowing back to supply water to the hair, and the overheat of the ultrasonic vibrator inside the handle Control circuit using a thermistor that detects the temperature of the ultrasonic vibrator to prevent In the furnace, the ultrasonic vibrator was operated and deactivated according to the resistance value of the thermistor.In the control circuit, a power switch that cuts off the initial power supply, a high frequency generator circuit applied to the ultrasonic wave, and a semiconductor device such as SCR or triac and IC are used. By controlling the supply of power to the ultrasonic vibrator, the control circuit is configured to adjust the intensity of the ultrasonic vibrator. The rectifier circuit including the external power supply and the transformer, the charging power supply, can be connected in parallel with the rechargeable battery in the handle. The power supply is attached to the connector so that the power supply can be used.In case that the user needs to use the product for a long time or the continuous use, separate the circuit from the handle to separate the circuit from the outside so that the power supply and the ultrasonic intensity can be adjusted from the outside. It was made.

Normally, ultrasonic waves are sound waves of 20 KHz or more. Ultrasonic frequency bands that generate air bubbles are generated around 1 MHz. Ultrasonic oscillators generating 50 KHz ~ 2 MHz ultrasonic waves and generating the above effects can be related to any ultrasonic vibrator. However, in the present invention, by applying power to both ends of the piezoelectric ceramics, the ultrasonic vibrator using the ultrasonic wave generated by the collision of electrons is applied to apply the ultrasonic vibrator directly to the hair while applying water and water-soluble liquid to the hair. Ultrasonic vibration was applied to the water and the water-soluble liquid between the ultrasonic vibrators to finely pulverize the water droplets during the operation of the ultrasonic vibration to supply the water and the water-soluble liquid directly to the hair.
