Description

Hair styling device {Hair styling device}

The present invention relates to a hair styling device, and to a hair styling device capable of easily directing hair by opening and closing two arms having a heating part for straightening and a heating part for curling and rotating by a driving part. .

In general, for hair styling, two heating plates called pan curlers face each other for hair straightening, and the installed arms are combined with an elastic hinge to hold the hair properly with one hand, and the two arms with the other hand at the proper pressure. Hair straightening while grasping.

And for hair curling, a curling iron with a heating part in the form of a cylinder is used. In this case, in order to wind the appropriate hair in the curling iron, a comb-shaped elastic hook is provided around the cylinder so that the hair is caught and rotated while drying. Thus, a method of directing a curling style is known. (Korean Patent Laid-Open Patent 10-2013-0109125 Rotary Roll Straightener)

Another known technology is a hair styling device (Korean Patent 10-1538288 hair styling device and hair styling method) having a rotating member configured to collect and wind hair while rotating around a cylinder-shaped barrel.

Another known technology related to the hair styling device is a technology for curling inside the chamber and allowing the curl to come out without loosening (Republic of Korea Patent Publication 10-2014-0008304).

As another styling device for hair curling, a device technology with a strand winding device (Korean Patent Publication 10-2018-0038488 a hair styling device for hair curling having an inclined mandrel and a winder) is known.

However, there is a problem in that it is not easy to quickly produce the desired curling with the above techniques, that is, the method of winding the hair through an elastic clasp to produce hair curling, or collecting the hair through a rotating member and winding the hair, The rest of the known techniques are easy to produce curling, but have a disadvantage in that the device itself is heavy because it is mechanically complex.

In addition, there is a disadvantage in that hair straightening and curling cannot be performed simultaneously with a single device, or in the case of a device that can be performed at the same time, it is only a manual method in which the hair is wound by hand, so it is difficult to quickly direct the desired hair.

The present invention is a technology that enables quick hair style directing while implementing the function of a pan curler for straightening hair and a function of a cylinder-shaped curling iron for hair curling style directing in one device in creating a hair style as described above. Provides.

In the hair styling device of the present invention, two semicircular arms 301 and 302 provided with a heating unit 400 are connected to an elastic hinge 304 coupled to the hinge body 305, and the rotating body 200 Inserted inside, the arm opening/closing guide holder 204 at the end of the rotating body 200 and the arm opening/closing guide holder 204 on the outside of each arm 301 and 302 and the arm opening/closing guide groove 306 By forming, the first arm 301 and the second arm 302 are opened and closed by an operation of moving the arm opening/closing/rotation switch 202 outside the rotating body part 200 in the front-rear direction.

The rotating body part 200 is connected to the handle part 101 so as to be rotatable.

To fix the position of the arm opening/closing guide groove 306 of the rotating body part 200 and the arm opening/closing guide holder 204 formed in each of the arms 301 and 302, the outside of the hinge body 305 and the rotating body part 200 ) The arm opening/closing slide gear 206 is formed inside so that they are engaged together.

Each arm (301,302) is configured in the form of inserting a straight elastic housing 430 into the curl housing 421, so that it has appropriate elasticity by the elastic housing elastic portion 431 of the straight elastic housing 430. This eliminates the need to use a separate elastic body.

The heating unit 400 is composed of a planar heating element, so that it is adhered to the curling housing 421 and the elastic housing bottom surface 433 of each arm 301 and 302 without a heating plate made of a metal material that stores heat. Energy consumption is reduced by transferring heat directly to the hair at (401,402,403,404).

Try to reduce it.

The planar heating elements 401 to 404 are a heating element 412 and an electrode 413 on a substrate 411 in which polyimide and Teflon are synthesized, an electrical insulating protective film 414, an infrared reflecting layer 415, The insulating layer 416 is formed by stacking in order. The heat insulating layer 416 is adhered to the curling housing 421 and the elastic housing bottom surface 433 by an adhesive, so that a portion of the substrate 411 comes into contact with the hair.

The hair styling device of the present invention is a device capable of straightening or curling hair with one device.In addition, when curling the hair, the hair is fixed at an appropriate pressure by two arms, and the hair is wound by rotating the curling iron body. Easy and quick curling

have.

In addition, since the heating unit is composed of a planar heating element and directly transfers heat to the hair without a hot plate made of metal, it is easy to control the temperature and drive low power consumption, so it is possible to create a hairstyle from the outside even with battery power without a power cord. Structure is relatively

Simple and light, it is easy to use.
