Description
FIELD OF INVENTION

The present invention relates to a multifunctional hair styling beauty electric heating device.


More particularly, the present invention relates to a multifunctional hair styling beauty electric heating device that easily styles the hair according to the situation by continuously rotating a hair styling part for gripping the hair clockwise or counterclockwise and opening an upper rotation body of the hair styling part in the state of gripping a grip body part and,


configures a grounding continuity structure for continuously supplying power to a hot plate installed inside the hair styling part continuously rotated as described above, and thus a heating state of the hot plate is also continuously maintained due to heating action of current when the hair styling part is continuously rotated to more effectively style the hair in various forms by the hair styling part, and


the hair is easily styled according to the situation and manipulation fatigue is also reduced, thereby improving user convenience.


BACKGROUND OF INVENTION

In general, a straightener for hair styling is a beauty device used to curl the hair using a heated hot plate, has an approximate shape of tongs, and is used to curl the hair in various shapes or straighten frizzy hair by curling long hair on the straightener or rotating the straightener appropriately.


In general, the hot plate of the straightener uses a heating wire that radiates heat as current flows, and the straightener uses a method of installing hot plates having a shape of tongs to face each other inside a body of the straightener and sweeping the straightener down while interposing the hair a user wants to style between the hot plates, and in this case, a degree of completion of curl and damage of the hair vary depending on the time when the hot plate is in contact with the hair and the pressure applied thereto. When the straightener is used, the heated hair is pulled from the beginning to the end of the air between the hot plates, and thus the hot plates tend to be adhered to the hair, and in this case, the fixation and the persistence of the set hair shape are improved, but there is a problem in that the hair is easily damaged while heat of the hot plate is strongly transferred to the hair. In addition, the straightener is sometimes used with a comb, and in this regard, the comb evens the hair entering the straightener and allows all possible hair passing through the straightener to curl or unfold in an appropriate direction, thereby increasing the degree of completion of curl. However, since both hands need to be used, it is not easy for an individual to simultaneously use the comb and the straightener while looking in a mirror alone. In this regard, according to the prior art related to a straightener, a comb is installed at one side of the straightener to allow the hair entering the hot plates to enter through the comb, but even if the straightener including the comb is used, the straightener needs to be strongly held to curl the hair well, and thus a problem in terms of damage to the hair due to this still exists. In general, the straightener is configured to rotatably install a pair of bodies via a hinge shaft on one side in a longitudinal direction, and in this case, when the straightener is used, the hand needs to keep gripping the bodies while keeping the bodies in close contact with each other, and also an operation of curling and pulling the hair needs to be repeatedly performed while holding the hand, and thus, there is an inconvenience in that considerable physical force is continuously required.


According to the background technology of the present invention, Korean Patent Publication No. 10-1788727 discloses a hair straightener. The straightener disclosed in the above Korean Patent Publication includes: a body formed like a column with a semicircular cross section and configured to receive external power; a heater connected to one end of the body and configured to receive power from the outside to generate heat; a presser having a shape corresponding to the body such that one surface thereof is in contact with the body and having one end connected to the other end of the body to rotate within a predetermined range; a pressurizer connected to the other end of the presser and configured to pressurize the hair of a user through an operation of the presser; and a guide part configured to guide the body and the heater connected thereto, and the presser and the pressurizer connected thereto so as not to be pushed when coupled,


the heater includes an upper surface inclined to both sides based on a longitudinal direction and a lower surface formed like a curve,


the pressurizer has a shape corresponding to the upper surface to be in close contact with the upper surface,


the guide part includes a dome-shaped protrusion formed at an end of the body, connected to the heater, an insertion groove having a shape corresponding to the protrusion to allow the protrusion to be fixedly inserted thereinto at the position of the presser, corresponding to the protrusion, and a cushion part that protrudes at a position connected to the pressurizer inside the insertion groove and having a rounded upper surface, and


the above Korean Patent Publication relates to a hair straightener in which the cushion part of the guide part is formed of a silicon material having heat resistance, and the body and one end of the presser are spaced apart from each other to prevent the hair of a user from being pinched when the protrusion is inserted into the insertion groove. The hair straightener of the above Korean Patent Publication has a function of increasing the volume of a root of the hair of the user to make the hair abundant by forming the upper surface of the heater to be inclined to both sides.


The present invention provides a hair styling beauty electric heating device for configuring grounding continuity to allow a hair styling part for gripping the hair to continuously rotate clockwise or counterclockwise and to continuously supply power to hot plates installed inside the hair styling part capable of continuously rotating, and thus, a heating state of the hot plate due to current heating is continuously maintained even during continuous rotation, thereby more effectively styling the hair in various ways by the hair styling part,

    • the grounding continuity structure is not a point-to-point contact structure, but a continuous surface-to-surface structure, which is capable of generating heat at high temperature compared to a point-to-point contact structure, resulting in excellent thermal efficiency, and


manipulation fatigue caused by hair styling is reduced by easily griping the hair between an upper rotation body and a lower fixation body by repeatedly performing a bending operation of the finger through the finger manipulator, and continuous rotation is also achieved by the lower fixation body, thereby easily styling the hair in various forms according to the situation. However, it is difficult to achieve such an effect from the art disclosed in the above patent.

In this case, although the case in which the grip body part 10 receives external power through the power line has been described, the present invention is not limited thereto, and a separate battery accommodation part (not shown) may also be formed inside the grip body part 10.


The finger manipulator 20 may have one side in a longitudinal direction, which is rotatably installed inside the grip body part 10, and the other side in the longitudinal direction, which is exposed in a downward direction of the grip body part 10, and accordingly, the finger manipulator 20 may be rotated through manipulation of the user finger.


That is, when the hair is gripped between the lower rotation body 31 and the upper rotation body 32 of the hair styling part 30, the finger manipulator 20 may easily grip the hair and may position the hair between the lower rotation body 31 and the upper rotation body 32 by rotating the upper rotation body 32 upward only through a bending operation of the finger.


In this case, a separate elastic spring (not shown) for applying elastic force to the finger manipulator 20 may be installed in the grip body part 10, and in this case, when the upper rotation body 32 to be described below is opened through manipulation of the finger manipulator 20, the elastic spring may be compressed, and when manipulation of the finger manipulator 20 is released, the upper rotation body 32 is folded toward the lower rotation body 31 by elastic force of the elastic spring, and accordingly, the hair may be easily gripped by the upper and lower rotation bodies 32 and 31. The finger manipulator 20 will be described below in detail.


The hair styling part 30 may include the lower rotation body 31 having one side in a longitudinal direction, which is rotatably installed along the guide piece 120 of the grip body part 10, and the upper rotation body 32 that is rotatably installed upward and downward with respect to the lower rotation body 31, and thus may generate heat by power supplied from the outside to style the hair appropriate for the situation.


That is, the hair styling part 30 may be used to straighten the hair by sweeping down the hair while being gripped between the upper rotation body 32 and the lower rotation body 31 or to curl the hair by rotating the hair styling part 30 while being gripped between the upper rotation body 32 and the lower rotation body 31.


In this case, when the hair is gripped between the lower rotation body 31 and the upper rotation body 32, the upper rotation body 32 may be folded toward the lower rotation body 31 to easily grip the hair by rotating and opening the upper rotation body 32 upward through a bending operation of the finger caught in the finger manipulator 20 and then releasing the bending operation of the finger manipulator 20 in the state in which the hair is positioned between the lower rotation body 31 and the upper rotation body 32.


Here, the lower rotation body 31 may include a lower grip part 320 including a cap mount 322 at one side in a longitudinal direction thereof in the state in which a lower hot plate 321 for generating heat by power supplied from the outside is installed, a lower cover part 330 installed below the lower grip part 320, and a mounting cover 340 installed on the cap mount 322. In this case, a pair of long insert holes 323 may be formed in the cap mount 322, and an exposure hole 341 may be formed in the mounting cover 340.


The lower rotation body 31 may be rotatably installed by positioning the mounting cover 340 between the first and second fastening pieces 120a and 120b of the guide piece 120 in the state in which one side in a longitudinal direction of the lower rotation body 31 is positioned inside the grip body part 10.


The upper rotation body 32 may include an upper grip part 360 including an upper hot plate 361 mounted thereon to generate heat by power supplied from the outside, and an upper cover part 370 mounted above the upper grip part 360.


The up-down controller 400 may be installed to be connected to the hair styling part 30 and may rotate the upper rotation body 32 upward and downward by the finger manipulator 20 or may rotate the hair styling part 30 by the control button 110.


That is, when the finger manipulator 20 is manipulated, the upper rotation body 32 may be opened by the up-down controller 400, and when the control button 110 is manipulated, the hair styling part 30 may be rotated by the up-down controller 400, and accordingly, the hair may be curled.


Here, the up-down controller 400 according to an embodiment will now be described. The up-down controller 400 may include a driving motor 15 installed inside the grip body part 10 and driven through manipulation of the control button 110, a rotation manipulator 420 that is connected to a driveshaft of the driving motor 15 to rotate the hair styling part 30 in that state of being installed at one side in a longitudinal direction of the lower rotation body 31, and an upward rotation guide part 460 that is formed at one side in a longitudinal direction of the upper rotation body 32 to be connected to the rotation manipulator 420 and to open the upper rotation body 32 when the finger manipulator 20 is manipulated.


In this case, the rotation manipulator 420 may include a close mounting part 430 installed at one side in a longitudinal direction of the lower rotation body 31 and including a position mount hole 431 formed therein to slidably insert the upward rotation guide part 460 thereinto, a pair of rotation guide pieces 440 that extends toward the driving motor 15 from one side surface of the close mounting part 430 and to which one side in a longitudinal direction of the upward rotation guide part 460 is coupled via a hinge shaft 441, and a shaft rotation connector 450 that extends toward the driving motor 15 from one side of the close mounting part 430 while being positioned between the rotation guide pieces 440 and connected to a driveshaft of the driving motor 15.


Here, the rotation manipulator 420 may be installed between the cap mount 322 and the mounting cover 340, and the shaft rotation connector 450 may protrude toward the driving motor 15 through the exposure hole 341 of the mounting cover 340.


The upward rotation guide part 460 may include an extension guide plate 461 that extends from one side in a longitudinal direction of the upper rotation body 32 and is slidably inserted into the position mount hole 431, and a receiver 462 that is formed at an end of the extension guide plate 461, is coupled to the rotation guide pieces 440 via the hinge shaft 441, and has a lower side in a longitudinal direction, which extends toward an internal lower side of the grip body part 10, that is, one side in a longitudinal direction of the finger manipulator 20.


Here, the position mount hole 431 may be connected to the long insert holes 323 of the cap mount 322, and thus the extension guide plate 461 may be slidably inserted into the long insert holes 323 and the position mount hole 431.


An operating state of the up-down controller as configured above will now be described. First, when the upper rotation body 32 is rotated upward to be opened, if the finger manipulator 20 is manipulated, one side of the finger manipulator 20 may pressurize the receiver 462 of the upward rotation guide part 460, and thus, the upper rotation body 32 may be rotated upward based on the hinge shaft 441 and may be opened.


Then, when manipulation of the finger manipulator 20 is released, the upper rotation body 32 may be folded toward the lower rotation body 31 by elastic force of the elastic spring to easily grip the hair.
