Description
- The present invention relates to a curling iron with rotatable and detachable structure, and more particularly, to an automatic curling iron having a structure in which a cylindrical heating body is easily separable from a main body, with the consequence that the cylindrical heating body can be replaced with a different cylindrical heating body having a brush, and the automatic curling iron not only occupies a small volume when stored but also simplifies hair styling since the cylindrical heating body is rotated to the left merely by operating a switch button.
- A hair-curling iron is widely used as a kind of beauty tool for styling hair, such as straightening wavy or curly hair or curling or waving straight hair.
- A conventional hair-curling iron is divided into a wave curling iron for creating hair in a wavy style and a straight curling iron for straightening hair. For this reason, there is a problem of poor economy in that a user must possess and use both types of curling irons in order to create various hairstyles.
- Moreover, when using each curling iron, there is a disadvantage in that the user must use the curling iron while holding a separate brush in the other hand to trim hair.
- In addition, the conventional hair-curling iron as described above is manufactured in the form of tongs, and has a heating part formed at the front end thereof. Since the surface of the heating part that is in contact with hair is mainly a flat surface, the user has to pull the heating part with great force to straighten the hair, thereby causing the hair to fall out due to the excessive force. When creating wavy hair, the user has to perform multiple operations on the same hair, such as manually picking up the hair and then rolling it up with the curling iron, which may cause damage to the hair due to heat and may quickly fatigue the user's wrist due to the lengthy work.
- In addition, in the state in which all types of curling irons with respective functions, such as a function of applying heat to the hair, a function of making the hair wavy, and a function of combing the hair, are separately provided, the use must replace the curling iron with a new curling iron every time it is used, and then apply power thereto to use it. Accordingly, there is a need to develop a curling iron that can perform all these functions in a single device.
- In order to solve this issue, Korean Patent Application Publication No. 10-2012-0090486 discloses, as illustrated in
FIG. 12 , a rotary hair-curling iron equipped with a detachable heat dissipation roll for styling hair by applying heat to the hair, the rotary hair-curling iron including: aheat dissipation body 10 having a handle member 11 formed thereon; aheat dissipation roll 20 detachably coupled to one end of theheat dissipation body 10 to radiate heat while rotating; aheating element 30 installed in theheat dissipation roll 20 to generate heat; a rotatingmember 40 installed in theheat dissipation body 10 to rotate theheat dissipation roll 20; apower supply unit 50 formed on theheat dissipation body 10 to turn on/off theheating element 30 or the rotatingmember 40; and anoperation adjustment unit 60 formed on theheat dissipation body 10 to adjust the heating temperature of theheating element 30 and the speed of rotation of the rotatingmember 40, wherein acoupling part 21 is detachably coupled to one end of theheat dissipation body 10 for rotation. - However, although the above patent describes that the
heat dissipation body 10 and theheat dissipation roll 20 are detachable through thecoupling part 21, it does not disclose a structure for supplying power to the heating element by any specific means while the heat dissipation roll rotates. - In order to solve this issue, Korean Utility Model No. 20-0394529 discloses, as illustrated in
FIG. 13 , a hair styling iron including: ahandle unit 30 including adrive motor 44 driven by power from a power source, areducer 46 connected to the rotary shaft of thedrive motor 44 to reduce the speed of rotation of thedrive motor 44, and power transmission means 48, 50 and 52 for transmitting rotational driving from thereducer 46; and aheating unit 10 including anintermediate connection part 24 provided with transmissionpower receiving means handle unit 30, and aheating rod 12 rotatably coupled to theintermediate connection part 24 and having a built-in thermal conductor configured to rotate together with a heatingrod rotation gear 29 by the rotation of the transmissionpower receiving means intermediate connection part 24, wherein one of thehandle unit 30 and theheating unit 10 is axially fitted to the other of them, thehandle unit 30 and theheating unit 10 are configured such that one of them is provided with a power transmission outlet 38 and the other is provided with a power transmission plug 18, and amovable clutch 40 and a drivenclutch 20 are provided between the power transmission means 52 and the transmission power receiving means 28 to easily attach/detach theheating unit 10 with respect to thehandle unit 30. - In the case of Korean Utility Model No. 20-0394529, since the hair styling iron must be equipped with expensive components such as the transmission power receiving means, the movable clutch and the driven clutch, the motor, and the gear box, there is a problem in that the hair styling iron has a complicated structure and is manufactured at high cost.
- Therefore, there is a need to develop a curling iron, which can have a detachable heat dissipation roll while supplying power to the heating element mounted on the rotating heat dissipation roll, have a simple structure, and be manufactured at low cost.

detachable lever 114 having thespring 114 b installed thereon is pressed, thefitting protrusion 114 c is separated from theguide groove 136 a, thereby enabling coupling/decoupling of thecylindrical heating body 130. - Hereinafter, a method of using the automatic curling iron with rotatable and detachable structure according to the present invention will be described.
- After a user turns on the power of the automatic curling iron by pressing the first switch part, the user can adjust a heating temperature and then rotate the cylindrical heating body leftwards and rightwards using the second switch part.
- When the use of the automatic curling iron is complete, the cylindrical heating body can be returned to its original position by pressing the home button of the second switch part.
- After use, the automatic curling iron can be stored with the main body and the cylindrical heating body separated from each other, or the cylindrical heating body can be replaced with a different cylindrical heating body having a brush. To this end, the main body and the cylindrical heating body can be easily separate from each other by pressing the detachable lever so that the fitting protrusion is separated from the guide groove, and then pulling the main body and the cylindrical heating body. As is apparent from the above description, in the automatic curling iron with rotatable and detachable structure according to the present invention, since the cylindrical heating body is easily separable from the main body, the cylindrical heating body can be replaced with a different cylindrical heating body having a brush, and the automatic curling iron not only occupies a small volume when stored but also simplifies hair styling since the cylindrical heating body is rotated to the left merely by operating a switch button. In addition, the automatic curling iron has a simple internal structure and can be manufactured at low cost.
