In general, hair styling tools are used to straighten hair that has been matched and to curl hair or curl hair. In the case of a hair styling device such as a hair styling device, a heating element is provided and the hair is deformed by applying heat at a certain temperature to the user's hair.

At this time, the ironing unit has a power cable for connecting an external power source and the heat plate to supply power to the heat plate, and the power cable is connected to an AC power source such as an outlet.

However, since the cord iron can be used only at a place where AC power is supplied, it can not be used outside, and the power cable is limited in its movement by its length.

In order to solve such a problem, a cord type iron filler which can be used by charging the power source has been proposed. As a related technology, Korean Patent No. 10-1092407 discloses a heat radiating plate for radio hair ironing and a cordless hair iron.

However, in the conventional portable ironing machine, the user must continuously apply the operation force in such a manner that the user touches the hair to be deformed and sweeps down. Generally, considering that hair styling is performed in busy morning hours, it is inconvenient to use such a portable hair iron while doing various work at the same time.

Some embodiments of the present invention have been made to solve the above-mentioned problems, and it is an object of the present invention to provide a thermal hair roll that a user can easily use while doing other work.

It is to be understood, however, that the technical scope of the present invention is not limited to the above-described technical problems, and other technical problems may be present.

According to an aspect of the present invention, there is provided a thermal hair clip comprising: a cylindrical body made of a conductive material; A heat generating film which is attached to a part of the inner peripheral surface of the main body and generates heat; And a power supply control module that controls the temperature of the heating film through power supply control by transmitting external power supplied through the power terminal to the heating element so that the heating element can generate heat.

According to any one of the above-mentioned objects of the present invention, the portable device is easily portable and wirelessly used, so that the user can use the device regardless of the place. In addition, the charging state of the heating hair roll can be visually confirmed through the power indicator.

In addition, by controlling the amount of current supplied to the heating film, the temperature of the heating surface of the thermal hair roll can be controlled, thereby providing an optimal temperature for curling the hair and preventing problems caused by overheating of the temperature can do. Further, the heat-generating surface cover part can prevent the user's image from being damaged even if the user touches the heating surface of the thermal hair roll, and can prevent the user's hair from being damaged due to overheating.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and similar parts are denoted by like reference characters throughout the specification.

Throughout the specification, when a part is referred to as being "connected" to another part, it includes not only "directly connected" but also "electrically connected" with another part in between .

1 is a block diagram of a thermal hairrout according to an embodiment of the present invention.

Referring to FIG. 1, the thermal hair roll of the present invention includes a main body 10, a heat generating film 20, and a power supply control module 40.

The main body 10 may be formed in a cylindrical shape made of an electrically conductive material. The heat generating film 20 may include a heat generating element attached to a part of the inner peripheral surface of the main body 10 to generate heat. The power supply control module 40 controls the power supply to control the temperature of the heat generating film 20 by controlling the power supply to the heat generating film 20 by supplying the external power supplied through the power supply terminal to the heat generating film 20, . Illustratively, in the thermal hair roll of the present invention, when the power is supplied, the heating element of the heating film 20 attached to the inner peripheral surface of the body 10 generates heat, so that the temperature of the conductive body 10 is raised . In addition, the thermal hair roll of the present invention can be controlled by the power supply control module 40 such that the heating element of the heating film 20 does not generate excessive heat. Thus, a curling effect can be obtained by simply winding the hair hair roll of the present invention on the user's hair. In addition, since it is not necessary to constantly apply the operation force to the user's hair as in the case of a hemp, it is possible to do other work after winding the hair hair roll once.

FIG. 2 is a perspective view showing a detailed configuration related to a main body of a thermal hairroll according to an embodiment of the present invention, FIG. 3 (a) is a sectional view showing a detailed configuration related to a main body of a thermal hairroll according to an embodiment of the present invention, 4 is a plan view of a heat generating film according to an embodiment of the present invention, FIG. 5 is a schematic view of a power control module according to an embodiment of the present invention Is a perspective view illustrating a state in which the fixing clip is coupled to the body of the thermal hair roll according to the embodiment of the present invention.

1 to 3A, a thermal hair roll according to the present invention includes a main body 10, a heat generating surface cover portion 11, a lid portion 12, a power indicator 6, a power indicator 14, A film 20 and a power supply control module 40.

The main body 10 may be formed in a cylindrical shape made of an electrically conductive material. It may be formed in a cylindrical shape, but may be formed by simply bending in a round shape. For example, the main body 10 may be made of aluminum, but is not limited thereto. Therefore, when heat is generated from the heating element in the heating film 20 described later, heat can be effectively diffused into the main body 10 within a short time. Illustratively, the diameter of the body 10 may be 30 mm, but is not limited thereto.

The heating surface cover portion 11 may be formed so as to surround the outer circumferential surface of the main body 10. The heat-generating-surface cover portion 11 serves to prevent the heat of the main body 10 from being released and to maintain the warmth of the main body 10. The heat generating surface cover portion 11 can be adhered to the outer peripheral surface of the main body 10 through the heat resistant adhesive.

The heating surface cover portion 11 may be made of a velvet material or a velcro material.

When the heating surface cover portion 11 is made of velvet, it prevents the burn accident when the user picks up the hair roll. At the same time, the temperature of the surface of the main body 10 is transferred to the hair as it is, and the function of preventing hair damage due to excessive heat is also performed, and the antistatic function can also be performed. In addition, the body 11 having a high conductivity has a high heat conductivity, and the heat emission is fast. By the way, since hair rolls are generally used with the hair fixed for a few tens of minutes, the heat of the hair roll surface needs to be maintained for a long time. At this time, the heat-generating surface cover part 11 made of velvet has a high thermal insulation property due to the characteristic of nylon material, so heat can be stored for a long time.

Here, preferably, the thickness of the velvet may be 1-5 denier. Preferably 3 denier. A denier usually refers to the thickness of yarn A g when it is pulled out about 9 km of yarn.

Nylon fiber or nylon fiber may be formed of a nylon tow in the form of a thick bundle of about 5 to 100,000 strands.

The velvet may be made of a nylon material or a rayon material, and when the nylon material is made of a polyamide (POLYAMIDE 6.6), it is not limited thereto. Such a polyamide preferably has a bright color such as white and has a decomposition temperature of 632 ℉, a starting temperature of 266 ℉ and a melting point of 254 캜 to 263 캜 at a boiling range 489 to 505 DEG F), and the molecular weight may be 19,000 to 30,000. These nylons are characterized by excellent mechanical strength, heat resistance, abrasion resistance, chemical resistance and electrical insulation.

Meanwhile, in a further embodiment, the velvet may be formed by the following process.

According to one embodiment of the present invention, it may be formed on a cylindrical conductor (for example, aluminum) using nylon powder or rayon material in powder form. Velvet powder of other materials can also be utilized.

First, a material inspection is performed on a powder made of polyamide to determine whether it is a defective material.

And removes oil. If the oil and the conductor remain in the powder and the powder, the adhesion to the conductor of the powder is remarkably lowered, so the oil is removed in advance.

Next, the primer is applied to the oil-removed conductor surface (i.e., the outer circumferential surface) and dried. Primer application is a task that is performed spontaneously to strongly bond the velvet cover to the conductor. After the primer has been applied, the primer is dried at 40-60 ° C for 5-15 minutes. Preferably, the first drying step may be carried out at 50 DEG C for 10 minutes. When the temperature is lower than 40 ° C or when the temperature is higher than 60 ° C, the activity of the primer is lowered or the degree of adhesion is lowered, so that the optimum drying condition is in the range of 40-60 ° C.

The adhesive is applied to the surface of the conductor coated with the primer. The adhesive may be a SA321 aqueous binder.

Next, a fabric layer (i.e., a yarn) is formed on the surface of the conductor coated with the adhesive, and a pile composed of the powder is flocked and dried on the fabric layer. The fabric layer is formed by interwoven weft yarns and warp yarns and serves to form a velvet while the yarn is double inserted into the area between the weft yarn and the warp yarn. At this time, the flocking method can be carried out by spraying the powder on the surface of the conductor. At this time, the powder may be sprayed only in a predetermined position and direction, and the powder may be uniformly sprayed on the surface of the conductor by rotating the conductor with respect to the central axis of the cylindrical structure of the conductor. For example, after a cylindrical conductor is inserted into the outer circumferential surface of a rotating rod rotating about one axis, the powder may be injected through a jet mechanism located on the upper side of the rotating rod. At this time, the injection mechanism may spray the powder while horizontally moving in the longitudinal direction of the conductor, in order to form a uniform and dense cover on the surface of the conductor. Alternatively, the powder may be sprayed at various positions while the conductor is fixed.

In a further embodiment, the pile may be applied by applying powder to the fabric layer and then applying a voltage. Generally, the sprayed powder does not exhibit a specific directionality. However, when a conductor in which powder is injected into an electric furnace is charged and charged at a predetermined voltage, the powder may be combined with an electrode to complete the filling.

In the case of drying, the second dried step can be carried out by drying the flocked pile at 40-60 ° C for 1-10 minutes. Preferably, it can be dried at 50 DEG C for 5 minutes.

Then, a heat treatment is performed on the conductor having completed the flocking. The heat treatment may be performed by heating the conductor in the range of 110-130 DEG C for 5-15 minutes or by heating the air in the chamber where the conductor is located or by heat transferring to the surface of the conductor. The bonding state may not be completely fixed, and when it is higher than 130 ° C, the binding force of the files may be rather broken or the adhesive strength of the adhesive may be lowered. In this case, since it is difficult to obtain a velvet cover having a uniform composition, 110-130 ° C is the optimum heat treatment range.

Remove dust from the surface of the conductor. Dust can be removed from the surface of the conductor by impacting the conductor or by injecting wind. Injecting wind here can mean blowing the conductor surface to remove dust on the surface. For example, when an impact is applied, the conductor will momentarily move from its original position to another position, where dust on the conductor surface may separate from the conductor. Alternatively, dust may be removed from the entire surface of the conductor by inserting the conductor into the outer circumferential surface of the rotating rod and rotating it around the central axis of the rotating rod, while providing wind through the air injecting mechanism provided at one side.

In addition, when the heating face cover portion 11 is made of Velcro, the hair is entangled due to the nature of the velcro material, so that the hair can be easily fixed to the body when the hair is rounded on the outer peripheral surface of the body 11. The Velcro may be made of 100% nylon (NYLON 6), and the length of the Velcro may be formed to correspond to the circumference and length of the body 10. For example, Velcro can include Oxford paper, which has the advantage that design insertion is easy. That is, the heating face cover portion 11 can be formed by planting the velcro on the Oxford paper cloth, and the velcro clogging the hair can be added after various design designs are inserted into the Oxford paper.

For example, one area of the heating surface cover portion 11 may be made of velvet, and the other area may be made of velcro. That is, it may be configured such that velvet is applied on the outer circumferential surface of the body 10, and velcro is applied on the velvet. This has the advantage of maintaining the thermal insulation of the velvet, and the disadvantage that the hair slips due to the hooking characteristics of the velcro can be overcome.

 The heat generating film 20 may include a heat generating element attached to a part of the inner peripheral surface of the main body 10 to generate heat.

Referring to FIG. 4, the heat generating film 20 may include a heat generating body 21 and a film 22 covering the heat emitting body 21. A power supply control module 40, which will be described later, is connected to both ends of the heating element 21 so that external power can be supplied.

The heating element 21 may be formed by folding in a zigzag shape corresponding to the shape of the film 22. Illustratively, the heating element 21 may be disposed corresponding to the rectangular film 22 having a width of 20 mm and a length of 40 mm. At this time, the heating element 21 is disposed at one end of the heating element 21 at the edge of the width of the film 22, and may extend in the longitudinal direction of the film 22 from one end. Then, the heating element 21 may be bent toward the direction in which the one end of the heating element 21 is disposed so as not to deviate from the area of the film 22. The heating element 21 can be bent in a zigzag fashion five times in this manner repeatedly. At this time, the other end of the heat emitting body 21 may be arranged to face one end of the heat emitting body 21. In addition, the film 22 can cover the heating element 21 so as to surround the front and back. Due to the shape of the heating element 21, the film 22 of the optimum size necessary for surrounding the heating element 21 can be used. Since the resistance is inversely proportional to the area, the heat generating element 21 can be smoothly provided with a heat generating function only if it is formed to have a small width. Therefore, the heat generating elements 21 are formed in a zigzag form so as to cover the entire area of the heat generating film 20, while being formed to have a thin width such as a line. As a result, the area of the heat generating element 21 contacting the main body 10 is increased, so that heat can be efficiently transferred.

The area of the heat generating element 21 may be 10 to 30% of the inner peripheral surface area of the main body 10. When the area of the heat generating element 21 is smaller than 10 to 30% of the inner peripheral surface area of the main body 10, the conductive area is significantly reduced. Therefore, the temperature rising speed of the main body 10 is considerably slow, May be generated. That is, according to one embodiment of the present invention, since the temperature of the main body 10 can be optimally heated to the target temperature within a short period of time without much use of the heat generating film 20, Can be produced.

At this time, when external power is supplied to the heating element 21, the temperature of the heating element 21 is preferably 150 to 200 ° C. In this case, the temperature of the main body 10 heated by the heating element 21 is 80 to 100 ° C, and the temperature of the heating surface cover portion 11 surrounding the main body 10 may be 40 to 70 ° C. This does not feel hot even if the user's hand touches the heating face cover portion 11 directly, but it may be a temperature sufficient for hair styling.

Here, the heating element 21 may be formed of a resistive wire or an etching foil heating wire, but is not limited thereto. Preferably, the heating element 21 may be a column heating film. Resistive wire or etched foil hot wire has excellent chemical resistance, resistance to electrical noise, and high heat resistance. Resistance and heat generation can be achieved at a temperature of 150 ° C or higher in the case of this configuration and 200 ° C or higher in the case of an etching foil hot wire.

In addition, the film 22 may be made of a polyimide film, but is not limited thereto. Such a polyimide film has a high level of resistance to chemicals and has an advantage of having excellent gas release characteristics in a high vacuum environment. In addition, the heat-generating film 20 described above can generate heat most efficiently at a voltage of 5V.

The lid portion 12 may be coupled to cover both open sides of the body 10, and may be configured as a pair. The lid portion 12 may be formed in the shape of a circular lid to cover the diameter of the body 10. Further, the lid part 12 is preferably made of a heat-resistant plastic having high heat resistance and light weight. As another example, the lid portion 12 disposed at the lower end of the main body 10 may be formed with a groove into which a later-described inserting portion of the battery portion is inserted, and the main body 10 can be supported by the battery portion.

The power indicator 13 may indicate whether or not power is supplied to the heat generating film 20. The power indicator 13 may be a high-brightness LED, which helps the user visually understand that the power is supplied.

Referring to FIG. 5, the power supply control module 40 may control the power supply to control the temperature of the heat generating film 20. FIG. The power supply control module 40 may be a combination of the printed circuit board 30 and the microcontroller 43.

Here, the printed circuit board 30, which is essentially included in the power supply control module 40, can supply external power to the heating element. The printed circuit board 30 is connected to the power supply terminal 14 to transmit the external power flowing through the power supply terminal 14 to the heating element. The printed circuit board (30) supplies current to the heating film (20) through two wiring lines.

 Here, the power terminal 14 may be a USB port, and may be connected to an electronic device such as a mobile phone, a notebook computer, a charger, etc. to receive power.

The printed circuit board 30 is connected between the power supply terminal 14 and the heat generating film 20 and the microcontroller 43 can be mounted on the printed circuit board 30. [

The microcontroller 43 can control the time at which current is supplied to the heat generating film 20. [

The microcontroller 43 has a timer function, and can flow a current to the heating element 21 only for a predetermined time. Illustratively, the microcontroller 43 can only allow current to flow to the heating element 21 for a time of 3 minutes 30 seconds to 4 minutes 30 seconds. As a result, the power control module 40 can supply current to the heating film 20 only for a time of 3 minutes 30 seconds to 4 minutes 30 seconds, and thereafter cut off the current.

The power indicator 13 is designed to receive a current from the printed circuit board 30. The power indicator 13 may be designed to be supplied with current by branching from the wiring for supplying current to the heating film 20. [ In this case, the power indicator lamp 13 operates only when a current is supplied to the heat generating film 20, so that the power indicator lamp 13 can be turned off when no current is supplied. The user has an advantage in that the power indicator 13 is turned off and the charging is completed (that is, the heating process is completed).

As a further embodiment, a capacitor (not shown) may be further added to the power supply control module 40, which is a combination of the printed circuit board 30 and the microcontroller 43. Here, the capacitor can have a current in the range of 1A or 2A, the rated power amount of the heat generating film 20 can be 115v or 28v, and the wattage density can be 2.4W / in2, 5W / in2 or 10W / in2.

 In this case, the capacitor means a capacitor, and the amount of current flowing through the capacitor is set differently according to the capacity while converting the AC voltage into the DC voltage and supplying the voltage. That is, it can serve to transmit only a small amount of predetermined current (for example, 1A or 2A) to the heating element 21 from the rated voltage in the general household.

In a further embodiment, the power supply control module 40 may be configured as a combination of the temperature sensor 41 and the printed circuit board 30.

In the case of the power supply control module 40 including the combination of the temperature sensor 41 and the printed circuit board 30, the printed circuit board 30 is connected between the power supply terminal 14 and the heat generating film 20, A temperature sensor 41 may be disposed on the film 20.

The printed circuit board 30 transmits external power supplied to the heat generating film 20 through the power supply terminal 14 and the temperature sensor 41 senses the temperature of the heat emitting body 21, If the predetermined threshold value is exceeded, the current supplied to the heating film 20 can be cut off. That is, the temperature sensor 41 is provided on the heat generating film 20 to sense the heat generating temperature of the heat generating body 21. [ At this time, the temperature sensor 41 may include a thermocouple which is composed of two kinds of metal wires and generates an electromotive force according to a temperature difference between the contact points.

Illustratively, when the temperature of the heating element 21 rises by 200 degrees or more, the power supply control module 40 can cut off the current supplied to the heat generating film 20. [

3A and 3B, the printed circuit board 30 supplies an amount of current to the heat generating film 20 through the heat generating film input terminal 31. As shown in FIG. Then, the current supplied through the heating film output terminal 32 is again returned to the printed circuit board 30, so that it has one complete circuit structure. In the printed circuit board 30, two wirings are connected to the power control module 40 and the heat generating film 20. That is, two wirings, each of which consists of in-wiring through which a current flows and out-wiring through which a current flows out, can be connected to the printed circuit board 30, the power supply control module 40, and the heat generating film 20, respectively. At this time, in the case of the heat generating film 20, it may be connected to the printed circuit board 30 through the end portion of the square shape formed in the left portion of the heat generating body of FIG.

3B, CON1 receives external power (for example, 220V AC voltage), and CON1 is connected to the microcontroller U1 and the indicator LED1 to supply power to the UI and LED1 To operate. (Connection wiring between respective components is not shown). Accordingly, when charging is being performed, the indicator lamp is automatically turned on. The microcontroller is connected in series with a small small circuit composed of two capacitors (Q1, Q2) and resistors (R3 to R5) in series and a small circuit is connected in series with two wires connected to the heating element do. That is, when the microcontroller supplies the current only for a specific time, the current is supplied to the heating element only for a specific time. In addition, the subcircuit portion performs a function similar to a capacitor to perform a function of converting an external AC power source into a DC power source. At this time, R3 is connected between Q1 and Q2, and R4 and R5 are connected between Q2 and the microcontroller.

For example, the heat-generating film 20 and the temperature sensor 41 may be fixed to the inner circumferential surface of the main body 10 through the heat-resistant tape, but the present invention is not limited thereto. Various methods (for example, Bond or the like). The heat-resistant tape is a heat-resistant tape, and has a performance that does not melt or adhere to a high temperature of 150-200 DEG C or more.

Referring to FIG. 6, the thermal hairroll of the present invention includes a locking clip 50 that encloses the outer side of the body 10 to press the body 10.

In one example, the fastening clamp 50 may include a plurality of holes extending perpendicularly to the transverse direction. The plurality of grooves 55 or the plurality of holes can serve as a handle, and the fixing jaws 50 can be easily attached to and detached from the seating groove of the case portion described later. As shown in FIG. 6, the shape of the holes may be formed in a heart shape, but it is not limited thereto, and various shapes of characters may be used to enhance the aesthetics. The fixing clip 50 may be fixed to wrap the wound hair while the hair of the user is wound around the body 10 and heated. In addition, the fixing clip 50 can more firmly fix the thermal hair roll to the user's hair. Further, the fixing tongue 50 may be made of a heat-resistant plastic having excellent heat resistance and light weight.

In a further embodiment, the fixed gripper 50 may include an upper frame and a lower frame surrounding the outside of the body 10 and a push handle provided at one end of the upper and lower frames to widen or narrow the space between the upper and lower frames .

Here, the pressing knob may be composed of an upper pressing knob and a lower pressing knob. The upper push handle can be rotatably coupled to an axle formed in one region of the upper frame. The lower push handle can be rotatably coupled to an axle formed in one region of the lower frame. At this time, each of the pressing knobs is rotatably disposed on the axial rod, but can be arranged so as to be rotatable only to a position where the respective pressing knobs are not in contact with each other. Specifically, the engaging jaws are disposed at positions adjacent to the axle in each frame, and the respective pressing knobs may not be in contact with each other because the rotatable region is restricted by the engaging jaws. The reason for this configuration is to allow the user to grasp the fixed clamp with two fingers and to make the gap between the frames open. On the other hand, by the user's selection, the upper pushing handle can be rotated and folded so as to come into close contact with the surface of the upper frame. Likewise, the lower push handle can be rotated and folded in close contact with the surface of the lower frame. Accordingly, when the fixed clamp is used for curling the hair, the push handle is disposed at a distance from the frame so that it can be easily used by hand. In addition, when the fixed clamp 50 is fixed to the main body 10, It can be stored as a single cylinder when it is brought into close contact with the surfaces of the upper and lower frames. As a result, the volume of the fixed gripper 50 can be remarkably reduced, which minimizes the volume of the portable and storage parts.

FIG. 7 is a perspective view of a fixing jaw according to another embodiment of the present invention, FIG. 8 is a view for explaining coupling of a fixing jaw, a battery, and a case to a main body according to an embodiment of the present invention, Sectional view showing a state in which a battery unit is coupled to a main body of the present invention.

7, the fixed clamp 50a corresponds to the longitudinal direction of the main body 10, and is formed to have a semicircular shape on the transverse section. A plurality of grooves 55 are formed at both ends at regular intervals Can be formed in the shape of a comb. Here, the fixed gripper 50a may be made of a flexible material having elasticity acting toward the main body 10. As another example, as shown in Fig. 8, the fixed clamp 50b may include a plurality of holes penetrating perpendicularly to the transverse direction. The plurality of grooves 55 or the plurality of holes can serve as a handle, and the fastening tabs 50a and 50b can be easily attached to and detached from the seating groove of the case portion described later.

 8 and 9, the thermal hair roll of the present invention is formed so as to correspond to the battery unit 70 and the main body 10 that supplies power to the heat emitting body 21 through the power supply terminal 14a, And a case portion 80 in which the main body 10 is housed through the opening.

The battery section 70 includes an insertion section 71 formed to be inserted into the groove 16 formed at the lower end of the main body 10 and a lower power terminal 72 connected to the power terminal 14a, A lower printed circuit board 75 which is disposed inside the housing 76 and connected between the lower power terminal 72 and the battery 74 to supply the current by the battery 74 to the heating element 21; And a lower power indicator 73 connected to the lower printed circuit board 75 and indicating whether power is supplied to the heating element 21. [ Illustratively, the power supply terminal 14a and the lower power supply terminal 72 may be configured to correspond to the shapes of the input terminal and the output terminal. The lower power terminal 72 may be a USB port and may be connected to an electronic device such as a mobile phone, a notebook computer, a charger, etc. to receive power. In other words, the power supply terminal 14a is a power supply and demand terminal of the thermal hair roll, and the lower power supply terminal 72 is a power supply terminal of the battery unit 70. When the two terminals 14a and 72 are connected, Can be connected to the thermal hair roll. That is, through the battery unit 70, the thermal hair roll of the present invention can increase the portability in an outdoor space without a power source. In addition, the battery unit 70 separately includes a power supply / discharge terminal (not shown) at the lower end, so that the power from the outside can be supplied / received through the power supply / demand terminal.
