Description

Technical Field

[0001] The present invention relates to a hair iron. More specifically, by floating a heating plate module in a housing space of a main body so as to have a heat dissipation space at a certain interval, while having styling fineness and a smooth operating feeling, it prevents heat generated from the heating plate module from being transmitted to the main body and can prevent burns, and relates to a hair iron.

Background Art

[0002] Generally, a hair iron is used to arrange a desired hair style, such as straightening curly hair or curling straight hair into a curly or wavy shape, by using heat to wind or sandwich the hair. In the past, hair irons with a shape in which metal rods crossed each other and were used by applying heat were mainstream. Recently, however, tong-shaped electric hair irons heated by electricity have become mainstream to enhance usability.

[0003] The heater of such an electric hair iron is heated by electricity supplied from the outside and generally consists of a metal material with excellent thermal conductivity so that rapid heating is possible. In particular, among metals, aluminum and aluminum alloys with excellent thermal conductivity are most frequently used.

[0004] However, when using a metal material with such high thermal conductivity as a heater, due to the high thermal conductivity, the heating plate becomes extremely hot in an instant, which may burn the hair or damage the keratin, a protein component forming the hair, causing strong damage to the hair and damaging the hair.

[0005] Furthermore, because the heater is made of metal, while it has excellent heat-generating properties, it not only cools down easily but also has a low thermal emissivity. As a result, the radiated high heat only acts on the surface of the hair and does not penetrate deep into the hair shaft. This not only prolongs the hair shaping time but also causes significant damage to the shaped hair, preventing it from returning to its original state.

[0006] Figure 1 is a schematic perspective view of a typical electric hair iron.

[0007] A typical electric hair iron, as shown in Figure 1, comprises a tong-shaped body 10 connected by a spring hinge 20 and held in an open position, and a pair of heaters 30 arranged opposite each other on the inside of the tip of the body 10 and heated by an externally supplied power source.

[0008] With the hair iron configured as described above, when the pair of heaters 30 are heated, and hair is placed between the pair of heaters 30, the main body 10 is moved in the closing direction, causing the hair to be pressed against the heaters 30. In this state, the main body 10 is pulled towards the ends of the hair to straighten it, or to curl or wave it, allowing the user to arrange the desired hairstyle as intended.

[0009] In this case, if the temperature of the heater 30 is too high, the hair is easily damaged by the high temperature, and conversely, if the temperature of the heater 30 is too low, the process of straightening the hair into the desired shape or styling it into curls or waves will not be successful. Therefore, it is important that the heater 30, which comes into direct contact with the hair, is always kept at a constant temperature.

[0010] Furthermore, conventional hair irons have the problem that, because the hair is in direct contact with the heater 30 while the hairstyle is being shaped, the high temperature damages the hair, causing it to break down, and also causes the hair to be pulled out between the heaters.

[0011] Thus, when metal materials with high thermal conductivity are used as heating plates, the high thermal conductivity causes the heating plate to become extremely hot in an instant, which can burn the hair or destroy keratin, the protein component that makes up the hair, causing severe damage to the hair and resulting in hair damage.

Mode for Carrying Out the Invention

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail based on the accompanying drawings. However, in the following description and the accompanying drawings, when explaining the present embodiment, if it is recognized that a specific explanation of a known function or configuration related to the present invention may obscure the gist of the present invention, the detailed explanation thereof will be omitted.

[0020] Also, it should be noted that throughout the drawings, the same reference numerals are given to the same components as much as possible.

[0021] The terms and words used in the present specification and claims described below are not to be construed as being limited to the ordinary meaning or the dictionary meaning, but are construed in accordance with the principle that the inventor can appropriately define the concept of the terms in order to explain the invention in the best way, and are construed in the meaning and concept corresponding to the technical idea of the present invention.

[0022] Therefore, the embodiments described herein and the configurations shown in the drawings represent only preferred embodiments of the present invention and do not represent the entire technical concept of the invention. It should be understood that there are various equivalent and modified embodiments that can be substituted for these at the time of filing this application.

[0023] Figures 2 and 3 are plan views showing a hair iron according to the first embodiment of the present invention, and Figure 4 is a diagram illustrating the levitation state of the heating plate module in the hair iron of Figure 2.

[0024] As shown in Figures 2 and 3, the hair iron according to the first embodiment of the present invention comprises a lower body 100 and an upper body 200 having a tong shape with one side of each being connected by a hinge and having housing spaces 110 and 210; a heating plate module 300 coupled to the inner housing spaces 110 and 210 formed by the engagement of the lower body 100 and the upper body 200 so as to float above the bottom surface with a certain gap between them; a flexible cable 400 coupled to one side of the heating plate module 300 to supply power to the heating plate module 300; a first magnet 500 configured on the other side of the heating plate module 300 to generate magnetic force; and a second magnet 600 configured on the other side of the lower body 100 and the upper body 200 to generate magnetic force to create an attractive force with the first magnet 500 configured on the heating plate module 300.

[0025] Here, concave housing spaces 110 and 210 are formed on the inner surfaces of the left ends of the lower body 100 and the upper body 200, respectively, and a flexible cable 400 is connected to one side of the heating plate module 300. The attractive force between the other side of the heating plate module 300 and the first magnet 500 and the second magnet 600 formed on the lower body 100 and the upper body 200, respectively, allows the heating plate module 300 to be positioned so that it can float with a certain gap from the bottom surface.

[0026] Furthermore, the heating plate module 300 is levitated in the housing spaces 110 and 210 of the lower body 100 and the upper body 200, respectively, and dissipates heat to style the hair.

[0027] Therefore, by levitating the heating plate module 300 housed in the housing spaces 110 and 210 of the lower body 100 and the upper body 200 by gravity, a heat dissipation space is formed between the bottom surface of the housing spaces 110 and 210 and the back surface of the heating plate module 300, thereby preventing the heat generated from the heating plate module 300 from being transmitted to the lower body 100 and the upper body 200 when using the hair iron, and thus preventing the risk of burns when using the hair iron.

[0028] In other words, as shown in Figure 4, with a flexible silicone cable 400 that supplies power to the heating plate module 300 configured on one side of the heating plate module 300, and the first magnet 500 built into the other side of the heating plate module 300, an attractive force is generated that causes the heating plate module 300 to stick together with the second magnet 600 formed on the lower body 100 and the upper body 200, respectively, causing the heating plate module 300 to levitate in the housing spaces 110 and 210 of the lower body 100 and the upper body 200.

[0029] On the other hand, when the lower body 100 and the upper body 200 are operated in the closing direction, the heating plate module 300 has a certain gap from the bottom surface of the housing space of the lower body 100 and the upper body 200, and adjacent portions of the housing space of the lower body 100 and the upper body 200 are in contact with each other with protruding parts, so that the heating plate modules 300 are separated from each other by a certain distance.

[0030] Furthermore, as shown in Figure 2, when the lower body 100 and the upper body 200 are moved in the closing direction, stepped portions 120 and 220 are provided on the front portions where the lower body 100 and the upper body 200 come into contact, corresponding to each other. At this time, even when the lower body 100 and the upper body 200 are folded via the stepped portions 120 and 220, the heating plate module 300 is formed in a shape in which the stepped portions 120 and 220 protrude in a corresponding manner so that a certain gap is maintained from the bottom surfaces of the lower body 100 and the upper body 200.

[0031] In addition, the second magnet 600 is built into the stepped portions 120 and 220, respectively.

[0032] As described above, in the hair iron according to the first embodiment of the present invention, the heating plate module 300, which is housed in the housing spaces 110 and 210 of the lower body 100 and upper body 200, is connected to one side by a flexible cable 400, and an attractive force is generated between the first magnet 500 configured on the other side and the second magnet 600 formed on the lower body 100 and upper body 200, respectively, with a certain gap between them, causing the heating plate module 300 to float within the housing spaces 110 and 210 at a certain distance from the bottom surface.

[0033] Therefore, since the heating plate module 300 is levitated and has no contact surface with the lower body 100 and the upper body 200, heat is not transferred to the main body, thus preventing the risk of burns to the user. Moreover, by using the hair iron with the heating plate module 300 levitated, hair styling can be performed smoothly without pulling out the hair.

[0034] Furthermore, the second magnet 600 is configured such that magnets with the same polarity are arranged on the inner surfaces of one end of the lower body 100 and the upper body 200, so as to generate a repulsive force, thereby causing the lower body 100 and the upper body 200, which are moved in the closing direction to hold the hair, to expand due to the repulsive force.

[0035] Here, the second magnet 600 is used as an expanding magnet to expand the lower body 100 and the upper body 200. That is, the second magnet 600 comprises a first expanding magnet built into the inner surface of the right end of the lower body 100, and a second expanding magnet built into the inner surface of the right end of the upper body 200 so as to exert a repulsive force on the first expanding magnet.

[0036] At this time, the first expanding magnet and the second expanding magnet are built into the lower body 100 and the upper body 200 respectively, having the same polarity and facing each other, and the repulsive force between them causes the lower body 100 and the upper body 200 to expand.

[0037] On the other hand, the corners on both sides of the heating plate module 300 are configured to have a rounded shape, and both sides of the interior of the housing spaces 110 and 210 also have a rounded shape corresponding to the corners of the heating plate module 300. Moreover, the stepped portions 120 and 220 also have a rounded shape and protrude.

[0038] Figure 5 is a plan view showing a hair iron according to a second embodiment of the present invention.

[0039] The hair iron according to the second embodiment of the present invention, as shown in Figure 5, is similar to the first embodiment of the present invention except that a reflector 700 is provided on the bottom surfaces of the lower body 100 and the upper body 200, which are the lower parts of the heating plate module 300 configured in the housing spaces 110 and 210 of the lower body 100 and the upper body 200, to prevent heat generated from the heating plate module 300 from being transferred to the main body.

[0040] In other words, as in the first embodiment of the present invention, the heating plate module 300, which is housed in the housing spaces 110 and 210 of the lower body 100 and the upper body 200, is levitated within the housing spaces 110 and 210 at a certain distance from the bottom surface by an attractive force between the first magnet 500 configured on the other side with a flexible cable 400 connected to one side, and the second magnets 600 formed on the lower body 100 and the upper body 200, respectively, with a certain gap between them. The reflector 700 further blocks the heat generated from the heating plate module 300 from being transmitted to the lower body 100 and the upper body 200, thereby preventing burns.

[0041] Figure 6 is a plan view showing a hair iron according to a third embodiment of the present invention.

[0042] As shown in Figure 6, the hair iron according to the third embodiment of the present invention, compared to the first embodiment, does not use the attractive force between the first and second magnets 500 and 600 to levitate the heating plate module 300. Instead, both sides of the heating plate module 300 are fixed to both sides of the housing spaces 110 and 210 of the lower body 100 and upper body 200 via a flexible cable 400 made of silicone material, and insulating protrusions 800 made of silicone material are formed at a certain interval below the heating plate module 300.

[0043] Therefore, the insulating protrusion 800 allows the heating plate module 300 to float at a certain distance from the bottom surfaces of the housing spaces 110 and 210 of the lower body 100 and the upper body 200. This prevents the heat generated from the heating plate module 300 from being transmitted to the lower body 100 and the upper body 200, thereby preventing the risk of burns to the user when using the hair iron.

[0044] Figure 7 shows a heating plate module in a hair iron according to the first to third embodiments of the present invention.

[0045] As shown in Figure 7, the heating plate module 300 is formed in the shape of a rectangular plate that is elongated in the left-right direction. The left-right length of the heating plate module 300 is formed to be shorter than the left-right length of the housing spaces 110 and 210, and as shown in Figure 3, a heat dissipation space is formed between the left and right ends of the heating plate module 300 and the left and right inner surfaces of the housing spaces 110 and 210, through a gap, allowing heat to dissipate.

[0046] The left and right ends of the heating plate module 300 are formed to be thinner than the height of the upper surface so that they can float in the housing spaces 110 and 210.

[0047] Therefore, the attractive force between the first magnet 500 and the second magnet 600 can cause the heating plate module 300 to float above the bottom surface of the housing spaces 110 and 210, or to float using the insulating protrusion 800. Furthermore, by further arranging the reflector 700 on the bottom surface of the housing spaces 110 and 210, the heat generated from the heating plate module 300 can be blocked from being transmitted from the lower body 100 and the upper body 200, thereby preventing burns to the user.

[0048] Due to the levitation of the heating plate module 300, a heat dissipation space is formed between the back surface of the heating plate module 300 and the bottom surfaces of the housing spaces 110 and 210, allowing the heat emitted from the heating plate module 300 to dissipate. As a result, the heat from the heating plate module 300 is not directly conducted to the lower body 100 and the upper body 200 but is transferred by convection, making it possible to use the hair iron when it is not too hot and preventing burns.

[0049] Furthermore, the heating plate module 300 comprises a main body portion 330 made of an aluminum plate having a long axis and a short axis direction, bent portions 340 in which both sides of the main body portion 330 are bent at a right angle in the longitudinal direction, a thin film heater 350 attached to the main body portion 330 between the two bent portions 340 by heat fusion, and an epoxy molding resin (EMC: Epoxy Molding) used to mold the upper end of the thin film heater 350. The device may also include: Compound 360; a Teflon® film 370 attached by heat fusion to the surface of the main body 330, excluding the EMC 360, including the side and surface of the bent portion 340; a temperature sensor (not shown) molded via the EMC 360 and located at the upper end of the film plate heater 350 to sense and transmit the surface temperature of the film plate heater 350; and a plurality of terminals (not shown) located on the upper part of one side of the film plate heater 350, partially molded via the EMC 360, and protruding further than the surface of the EMC 360.

[0050] The surfaces of the main body 330, the bent portion 340, and the lead frame portion are coated with an insulating material such as Teflon. This prevents the risk of electric shock.

[0051] The upper surface of the EMC360 is formed at the same height as the upper side of the bent portion 340, and a fuse insertion portion may be configured so that a fuse can be installed in a predetermined position during the molding of the EMC360. In this case, the fuse can cut off the power supply when a high voltage is applied to the film heater 350, thereby preventing electrical accidents. The terminals consist of two power supply terminals for supplying power to the film heater 350 and two connection terminals for connecting to the temperature sensor.

[0052] In addition, the terminals consist of a total of four terminals, with the two central terminals connected to the temperature sensor and the two terminals on either side connected to the film plate heater 350. The four terminals may be arranged in a row, or two terminals may be formed in a trapezoidal shape, with each terminal positioned further forward than the other two. On the other hand, as the temperature sensor, an NTC (Negative Temperature Coefficient) type sensor is used that directly detects and transmits the surface temperature of the film plate heater 350.

[0053] The main body portion 330, including the bent portion 340, has a "concave" shape, and the film plate heater 350 and EMC 360 are laminated in this order inside the "concave" shape, while the Teflon film 370 is formed on the outer surface of the "concave" shape, excluding the EMC 360. The Teflon film 370 is the part that comes into direct contact with the hair, and the EMC 360 is the part that is inserted into and fixed to the inside of the main body in Figure 2.

[0054] Therefore, according to the embodiments of the present invention described above, the heating plate module 300, which is disposed in the housing spaces 110 and 210 of the lower body 100 and the upper body 200, is levitated in the housing spaces 110 and 210 of the lower body 100 and the upper body 200 by the attractive force between the first and second magnets 500 and 600 or by the insulating protrusions 800, and is levitated so that it can move smoothly up and down. This makes it possible to create delicate hairstyles when styling hair by clamping it, and the heat emitted from the heating plate module 300 is dissipated through the heat dissipation space, so it is possible to use the hair iron when it is not too hot and prevent burns.

[0055] Furthermore, according to the embodiments of the present invention described above, the lower body 100 and the upper body 200 are smoothly expanded and contracted due to the repulsive force between the expanding magnets, which has the advantage of allowing for precise control of the hair iron.

[0056] On the other hand, the embodiments of the present invention described above are merely illustrative, and any person with ordinary skill in the art to which the present invention belongs will understand that various modifications can be made therefrom, and that other equivalent embodiments can be adopted.

[0057] Therefore, it will be clear that the present invention is not limited in any way to the embodiments mentioned in the detailed description section above.

[0058] Therefore, the true technical scope of protection of the present invention should be determined by the technical idea of ​​the appended claims, and the present invention should be understood to include the technical idea defined by the appended claims and all variations, equivalents, or substitutes within that scope.
