Description

Technical Field

[0001] This disclosure relates to a wireless hair straightener, and more specifically, to a wireless hair straightener having a dual invisible hinge structure, wherein the housing of the wireless hair straightener is easy to install and remove, and is not exposed to the outside when the hinges are engaged with the housing. Background Technology

[0002] Most traditional hair straighteners are corded straighteners with a power cord attached to the bottom. During use, the straightener is moved or rotated multiple times, and the cord is a major obstacle to this movement. To address this issue, cordless hair straighteners have recently been introduced.

[0003] Hair straighteners typically use a hinge structure to allow movement of the upper and lower arms. However, this hinge structure has drawbacks: it's unsightly due to its exposed parts and is susceptible to direct impact. Additionally, when using a charging cable, the cable can interfere with the straightener's movement.

[0004] Additionally, repeatedly moving the hair straightener between the open and closed positions puts stress on the internal wiring, causing it to age prematurely. Furthermore, due to the nature of hair straightener use, the handle should be compact enough for easy one-handed grip; these factors should be considered when designing the wiring configuration. Summary of the Invention

[0061] Figure 1 This is a perspective view showing the open and closed states of a wireless hair straightener 100 according to an embodiment of the present disclosure. Figure 1 (a) shows an example of the wireless hair straightener 100 in the on state. Figure 1(b) shows an example of the closed state. As shown, the wireless straightener 100 may include a first housing 112, a second housing 114, a first heater section (not shown), a second heater section 116, and a body section 118.

[0062] According to one embodiment, the first heater section and the second heater section 116 can receive power from a battery (DC power supply; not shown) disposed within the wireless straightener 100. In this case, the battery may be included in the body section 118. Furthermore, the first heater section and the second heater section 116 include a heating resistor (not shown) and can operate as a heating element using power supplied by the battery.

[0063] According to one embodiment, the first housing 112 can move the first heater portion between a closed position and an open position. Similarly, the second housing 114 can move the second heater portion 116 between a closed position and an open position. In the open position, at least a portion of the body portion 118 located between the first housing 112 and the second housing 114 can be exposed to the outside. On the other hand, in the closed position, most of the body portion 118 can be covered by the first housing 112 and the second housing 114.

[0064] According to one embodiment, the first housing 112 and the second housing 114 may accommodate at least a portion of the body portion 118. For example, the first housing 112 may accommodate a left portion of the body portion 118, and the second housing 114 may accommodate a right portion of the body portion 118. Additionally, the first housing 112 and the second housing 114 may each accommodate at least a portion of the first heater portion and the second heater portion 116. For example, the second housing 114 may accommodate a portion of the second heater portion in a manner that surrounds all but one of the other multiple surfaces of the second heater portion 116. In this case, at least one surface of the second heater portion 116 exposed to the outside may include the surface that comes into contact with the user's hair.

[0065] Figure 2 This is a perspective view of a wireless straightener with the first housing 112 and the second housing 114 removed according to an embodiment of the present disclosure. According to one embodiment, at least a portion of the lower side surface of the first heater section 210 may be configured to face at least a portion of the upper side surface of the body section 118. For example, when the first heater section 210 is in the closed position, the lower side surface of the first heater section 210 may face a portion of the upper side surface of the body section 118, and when the first heater section 210 is in the open position, a portion of the lower side surface of the first heater section 210 may face a portion of the upper side surface of the body section 118. Similarly, at least a portion of the lower side surface of the second heater section 116 may be configured to face at least a portion of the upper side surface of the body section 118.

[0066] According to one embodiment, the first heater section 210 may accommodate at least a portion of a plurality of wires (222, 224, 226, 228). For example, at least a portion of the third wire 226 and the fourth wire 228 among the plurality of wires (222, 224, 226, 228) accommodated inside the first heater section 210 may extend and be disposed in the first recess 212 of the first heater section 210. Figure 2 Only the first recess 212, which accommodates the third wire 226 and the fourth wire 228, is shown. The first heater section 210 may also include a second recess (not shown) where the first wire 222 and the second wire 224 are disposed. Furthermore, the second heater section 116 may include two recesses in the same manner as the first heater section 210 to accommodate at least a portion of the plurality of wires located between the second heater section 116 and the second housing 114.

[0067] According to one embodiment, in the body portion 118, at least a portion of a plurality of wires (222, 224, 226, 228) can be accommodated in a receiving portion 260 formed on the upper side of the body portion 118. Specifically, the plurality of wires (222, 224, 226, 228) arranged along two recesses can extend and be accommodated in the receiving portion 260. In this case, each portion of the plurality of wires (222, 224, 226, 228) accommodated in the receiving portion 260 may include multiple bending structures, which will be referred to later. Figure 4 A detailed description thereof is provided. Similarly, a receiving portion may be formed on the other side of the upper part of the body portion 118 to receive at least a portion of the multiple wires connected to the second heater portion 116.

[0068] According to one embodiment, the first hinge 240 and the second hinge 250 may be disposed at the lower part of the body portion 118. The first housing 112 is fastened to the first hinge 240 and is movable between a closed position and an open position about the first hinge 240. During this process, the first heater portion 210 may move together with the first housing 112 between the closed position and the open position. Similarly, the second housing 114 is fastened to the second hinge 250 and is movable between the closed position and the open position about the second hinge 250.

[0069] As shown in the figure, when the first hinge 240 is fastened to the first housing 112, the first hinge 240 can be accommodated within the first housing 112 and is not exposed to the outside. Similarly, when the second hinge 250 is fastened to the second housing 114, the second hinge 250 can be accommodated within the second housing 114 and is not exposed to the outside. With this configuration, an aesthetically pleasing wireless hair straightener with a dual concealed hinge structure can be provided, wherein the hinges are not exposed to the outside.

[0070] According to one embodiment, the body portion 118 may include an elastic member 230. Specifically, the elastic member 230 may be disposed at the bottom of the body portion 118 to provide an elastic restoring force, causing the first housing 112 to move from a closed position to an open position. Similarly, an elastic member may also be additionally disposed between the second housing 114 and the body portion 118.

[0071] Figure 3 This is an exploded view of a first heater section according to an embodiment of the present disclosure. According to one embodiment, the first heater section can be disassembled into a first component 210_1 and a second component 210_2. The first component 210_1 may be a structure for accommodating / fixing a heating resistor. The second component 210_2 may include a first recess 212 and a second recess 312 for accommodating multiple wires (222, 224, 226, 228). For example, a portion of the third wire 226 and a portion of the fourth wire 228 may be accommodated in the first recess 212, and a portion of the first wire 222 and a portion of the second wire 224 may be accommodated in the second recess 312.

[0072] The two recesses 212 and 312 can refer to recessed paths into which wires disposed between the first housing 112 and the first heater section are arranged. For example, the two recesses 212 and 312 are configured with appropriate width and depth to accommodate two wires, so that even when the first heater section moves between an open position and a closed position, multiple wires (222, 224, 226, 228) can be stably accommodated in the two recesses 212 and 312. With this configuration, a portion of the multiple wires (222, 224, 226, 228) can be disposed between the first housing 112 and the first heater section. The second heater section can also be constructed in a similar manner to the first heater section.

[0073] Figure 4 This is a perspective view showing the wiring arrangement between the body portion 118 and the two heater portions 116, 210 according to an embodiment of the present disclosure. Figure 4 (a) is a side perspective view of the two heater sections 116, 210. According to one embodiment, the first heater section 210 can be connected to the main body section 118 (e.g., the mainboard of the main body section) or the output section of the battery via a first set of wires (222, 224, 226, 228), and the second heater section 116 can be connected to the main body section 118 (e.g., the mainboard of the main body section) or the output section of the battery via a second set of wires (422, 424, 426, 428). A first portion P1 of the first set of wires (222, 224, 226, 228) can be accommodated within two recesses of the first heater section 210. Similarly, a first portion P1 of the second set of wires (422, 424, 426, 428) can be accommodated within two recesses of the second heater section 116.

[0074] According to one embodiment, the second portion P2 of the first set of wires (222, 224, 226, 228) and the second set of wires (422, 424, 426, 428) can be respectively accommodated in two receiving portions of the main body 118. In this case, the output portion of the battery (not shown) is located at the upper part of the main body 118, and one end of the second portion P2 side of the first set of wires (222, 224, 226, 228) and the second set of wires (422, 424, 426, 428) can be electrically connected to the output portion of the battery. The second portion P2 of the first set of wires (222, 224, 226, 228) and the second set of wires (422, 424, 426, 428) may include a bent portion. For example, the second part P2 is bent into a "Z" shape, "S" shape, etc., so that the tension applied to the multiple wires (222, 224, 226, 228, 422, 424, 426, 428) can be relieved during the movement of the two heater parts 116, 210 between the open and closed positions. This configuration can prevent the multiple wires (222, 224, 226, 228, 422, 424, 426, 428) from aging or breaking easily.

[0075] Figure 4 (b) is a rear perspective view of the second heater section 116. According to one embodiment, one end of the first portion P1 side of the second set of wires (422, 424, 426, 428) is electrically connected to the upper side of the second heater section 116 and supplies power to the second heater section 116. Similarly, one end of the first portion P1 side of the first set of wires (222, 224, 226, 228) is electrically connected to the upper side of the first heater section 210 and supplies power to the first heater section 210.

[0076] Figure 5 These are perspective views and exploded views of the body portion 118 according to an embodiment of this disclosure. For example... Figure 5 As shown in (a), the body 118 may include a locking device member 512, a battery 514, 516, and double hinges 240, 250.

[0077] According to one embodiment, the input portions of batteries 514 and 516 connected to an external power source (e.g., an AC power source for charging batteries) can be disposed at the lower part of the main body 118. Furthermore, the output portions of batteries 514 and 516 for supplying power to the first heater section and the second heater section can be disposed at the upper part of the main body 118. Specifically, the output portions of batteries 514 and 516 are disposed at the upper part of the main body 118 and electrically connected to the first heater section and the second heater section via multiple wires (222, 224, 226, 228, 422, 424, 426, 428).

[0078] like Figure 5 As shown in (b), the multiple wires housed in the receiving portion of the body portion 118 may include bends 522. According to one embodiment, a single wire may include multiple bends. In this case, each bend can be formed by bending (bending) in a different direction.

[0079] Figure 6 This is a schematic diagram illustrating the wiring structure of multiple wires (222, 224, 226, 228, 422, 424, 426, 428) according to an embodiment of the present disclosure. As shown, the first set of wires (222, 224, 226, 228) can electrically connect the first heater section 210 to the battery output section 610. Similarly, the second set of wires (422, 424, 426, 428) can electrically connect the second heater section 116 to the battery output section 610. Furthermore, the battery output section 610 can be located at the upper part of the body section 118, and the battery input section 620 can be located at the lower part of the body section 118.

[0080] As shown in the figure, the longitudinal length of the main body 118 is longer than the longitudinal length of the first heater section 210 and the second heater section 116. Therefore, when multiple wires (222, 224, 226, 228, 422, 424, 426, 428) extend from the battery output section 610 located at the upper part of the main body 118 towards the lower part of the main body 118, and then extend towards the upper part of the main body to connect with the lower sides of the first heater section 210 and the second heater section 116, the required length of the internal wires is longer than... Figure 6 The multiple wires (222, 224, 226, 228, 422, 424, 426, 428) are long. Since the length of the wires is proportional to the power loss, this configuration of the present invention can minimize the power loss of the wireless hair straightener and increase the usage time. Furthermore, as the volume of the wires housed in the main body 118 decreases, the overall volume of the main body 118, which serves as the handle of the wireless hair straightener, also decreases, thereby increasing user convenience.

[0081] Figure 7 An example of operation of the double hinges 240, 250, integrated into the body portion 118 according to an embodiment of the present disclosure is shown. As shown, the lower side of the body portion 118 may include the double hinges 240, 250, two guide holes 710, 720, first charging terminals 730, 740, and a DC charging port 750. Here, the first charging terminals 730, 740, and the DC charging port 750 may be configured to be electrically connected to an input portion (not shown) of a battery located inside the body portion 118.

[0082] Figure 7(a) shows an example of the protruding state of the double hinges 240, 250. According to one embodiment, at least a portion of the double hinges 240, 250 may protrude outward from the body portion 118 when no external pressure is applied to the double hinges 240, 250. Specifically, the two protrusions (not shown) of each of the double hinges 240, 250 may protrude in opposite directions. (See below for further details.) Figure 8 Describe the detailed structure of the protrusion.

[0083] Figure 7 The diagram shows the first and second housings removed, with the first and second housings respectively fastened to the first hinge 240 and the second hinge 250. In this case, the protrusion of the first hinge 240 can be fastened to a fastening groove (not shown) on the inner side of the first housing, thereby securing the first housing to the body portion 118. Thus, the first hinge 240 is not exposed to the outside of the wireless straightener. Similarly, the protrusion of the second hinge 250 can be fastened to a fastening hole (not shown) on the inner side of the second housing, thereby securing the second housing to the body portion 118.

[0084] According to one embodiment, when the lower part of the main body 118 is attached to the charging dock (not shown), power can be supplied to the wireless straightener through the first charging terminals 730 and 740. (See below for further details.) Figure 15 An example is described where the lower part of the main body 118 is attached to the charging dock. Additionally, the wireless hair straightener can also be powered when a DC charging cable (not shown) is connected to the DC charging port 750. With this configuration, the user can operate the wireless hair straightener using the DC charging cable even if the battery is not fully charged.

[0085] Figure 7 (b) shows an example of the retracted state of the first hinge 240. According to one embodiment, when the pressurizing device 760 is inserted along the first guide hole 710, a plurality of protrusions of the first hinge 240 can retract. Thus, with the retraction of the plurality of protrusions of the first hinge 240, the first housing can be installed and removed. Similarly, when the pressurizing device 760 is inserted into the second guide hole 720, a plurality of protrusions of the second hinge 250 can also retract, so that the second housing can be installed and removed.

[0086] Figure 8 This is a detailed drawing of a first hinge 240 according to an embodiment of the present disclosure. As shown, the first hinge 240 may include two protrusions 820 and 830, a hinge housing 810, and a guide hole 840. Here, the guide hole 840 may be... Figure 7 The guide hole 710 of the body portion 118 shown is connected to the guide hole. Although Figure 8Only the first hinge 240 is shown, but the second hinge 250 may also include two protrusions, a hinge housing, and a guide hole connected to the second guide hole 720. The first hinge 240 and the second hinge may be configured inside the body portion facing each other.

[0087] According to one embodiment, the hinge housing 810 can securely accommodate at least a portion of the two protrusions 820, 830. Thus, when a pressurizing device (not shown) is inserted into the guide hole 840 and an external force is applied to the two protrusions 820, 830 in a predetermined direction, the first protrusion 820 and the second protrusion 830 can move in the predetermined direction.

[0088] Figure 9 This is a diagram showing the first hinge with its hinge housing removed according to an embodiment of the present disclosure. As shown in the figure, Figure 9 Figure (a) shows an example where the first hinge is not subjected to an external force from the pressurizing device 760. According to one embodiment, the first protrusion 820 may have a first inclined surface 910, and the second protrusion 830 may have a second inclined surface 920. As shown, the first inclined surface 910 and the second inclined surface 920 are not parallel. Furthermore, the first protrusion 820 and the second protrusion 830 may be arranged in opposite directions on the same axis.

[0089] Figure 9 Figure (b) shows an example of the pressurizing device 760 applying an external force to the first inclined surface 910 and the second inclined surface 920 along a predetermined direction A. As shown, when an external force is applied to the first inclined surface 910 and the second inclined surface 920 along the predetermined direction A, the two protrusions 820 and 830 of the first hinge can retract. Specifically, the first protrusion 820 can move along a first direction C, and the second protrusion 830 can move along a second direction B, which is opposite to the first direction C. Here, direction A is a direction orthogonal to the B / C direction. Thus, the distance between the end of the first protrusion 820 and the end of the second protrusion 830 can be reduced from L1 to L2.

[0090] As shown above (refer to the reference) Figure 7 The two protrusions 820 and 830 of the first hinge 240 can be fastened to the fastening holes inside the first housing. However, when an external force is applied to the first inclined surface 910 and the second inclined surface 920 along a predetermined direction A, the fastening between each of the two protrusions 820 and 830 and the fastening hole can be released as the two protrusions 820 and 830 retract, thereby separating the first housing from the body.

[0091] Figure 10An example of a rotary connector assembly 1010 and a cable 1020 connected to a cordless hair straightener 100 according to an embodiment of the present disclosure is shown. Here, the cable 1020 can provide external power to the cordless hair straightener 100. Furthermore, when a user uses the cordless hair straightener 100 with the cable 1020 connected, the rotary connector assembly 1010 can prevent the cable 1020 from tangling. That is, when the rotary connector assembly 1010 is secured to the cordless hair straightener 100, even with the cable 1020 connected, the user can rotate the cordless hair straightener 100 indefinitely without tangling the cable.

[0092] Figure 11 An example of a cable 1020 being secured to a rotary connector assembly 1010 according to an embodiment of the present disclosure is shown. As shown, the rotary connector assembly 1010 may include an upper assembly 1130, a lower assembly 1140, and a cable securing member 1150. Furthermore, the upper assembly 1130 may include two snap-fit ​​portions 1110 and 1120. According to one embodiment, the rotary connector assembly 1010 can be secured to the body portion by means of the snap-fit ​​portions 1110 and 1120 through two guide holes included on the lower side of the body portion (not shown). Thus, the upper assembly 1130 of the rotary connector assembly 1010 can be securely attached to a wireless hair straightener.

[0093] According to one embodiment, the cable 1020 can be coupled to the lower assembly 1140. Specifically, the terminals of the cable 1020 can be coupled to the ports of the lower assembly 1140. When the cable fixing member 1150 is moved along direction B while the cable 1020 is coupled to the lower assembly 1140, the cable 1020 can be fixed and will not detach from the lower assembly 1140. Conversely, when the cable fixing member 1150 is moved along direction A, the cable 1020 can detach from the lower assembly 1140. This configuration prevents the cable 1020 from detaching from the lower assembly 1140 or the power supply from being interrupted during use of the wireless straightener.

[0094] Figure 12Examples of rotation directions A and B of the body portion according to an embodiment of the present disclosure are shown. As described above, the upper component 1130 of the rotary connector assembly 1010 can be secured to a guide hole included on the lower side of the body portion via two snap-fit ​​portions 1110 and 1120. Furthermore, the upper component 1130 and the lower component 1140 can be configured to rotate indefinitely while maintaining an electrical connection. Thus, the rotary connector assembly 1010 can electrically connect the cable 1020 to the charging terminal included on the lower side of the body portion, and allows the body portion to rotate indefinitely in direction A or direction B without causing the cable 1020 to become tangled. With this configuration, even if the user uses the wireless hair straightener with the cable 1020 connected to the lower component 1140, tangling of the cable 1020 can be prevented.

[0095] Figure 13 This is an exploded view of a rotary joint assembly 1010 according to an embodiment of the present disclosure. Figure 13 (a) is an exploded view viewed toward the upper assembly 1130. As shown, the cable fixing member 1150 can be hinged to the lower assembly 1140. In this case, when the cable fixing member 1150 is parallel to the rotation axis of the lower assembly 1140, the cable can be fixedly attached to the fixing member 1050.

[0096] Figure 13 (b) is an exploded view viewed toward the lower assembly 1140. As shown, the lower assembly 1140 may include second charging terminals 1330 and 1340. The second charging terminals 1330 and 1340 can be connected to the first charging terminals 730 and 740 of the main body. Figure 7 The cable is electrically connected to the first charging terminal of the main body.

[0097] Figure 14 This is a perspective view of a charging stand 1400 according to an embodiment of the present disclosure. When the user is not using the wireless hair straightener, the battery of the wireless hair straightener can be charged by mounting the wireless hair straightener on the charging stand 1400. As shown, the charging stand 1400 may include a mounting part 1410 and output terminals 1420 and 1430. In this case, both output terminals 1420 and 1430 may be composed of spring clips.

[0098] According to one embodiment, the mounting portion 1410 may have a recessed shape. Specifically, the mounting portion 1410 has a recessed shape that is the same as or similar to the outer surface of the lower side of the wireless hair straightener (or the first housing and the second housing), so that the wireless hair straightener is fixedly mounted by inserting the lower side of the wireless hair straightener into the mounting portion 1410. Furthermore, the output terminals 1420 and 1430 may be located inside the mounting portion 1410, so that the wireless hair straightener is charged when mounted on the mounting portion 1410. With this configuration, the output terminals 1420 and 1430 can be connected to the first charging terminals 730 and 740 of the main body (… Figure 7 An electrical connection is used to connect the cable to the first charging terminal of the main body. That is, the charging base 1400 can be used as a stand for the wireless hair straightener or as a charger. Figure 14 The cable is shown not connected, but it can be connected to the charging dock 1400 to charge the wireless hair straightener.

[0099] Figure 15 An example is shown of a wireless hair straightener 100 mounted on a charging dock 1400 according to an embodiment of the present disclosure. Figure 15 (a) shows an example of the wireless hair straightener 100 before it is mounted on the charging dock 1400. According to one embodiment, a magnet 1510 may be included on the underside of the wireless hair straightener 100. Furthermore, the charging dock 1400 may include a magnetic Hall effect sensor 1520 for sensing the magnet 1510. Before the wireless hair straightener 100 is mounted, the Hall effect sensor 1520 cannot sense the magnetic force of the magnet 1510, and therefore charging of the wireless hair straightener 100 will not be initiated.

[0100] Figure 15 Figure (b) shows an example of the wireless hair straightener 100 mounted on the charging stand 1400. As shown, the lower part of the wireless hair straightener 100 can be mounted on the mounting part of the charging stand 1400 and stably fixed. Furthermore, when the wireless hair straightener 100 is mounted, the magnet 1510 can approach the Hall effect sensor 1520. Thus, the charging stand 1400 can initiate charging of the wireless hair straightener 100 by sensing the magnetic force of the magnet 1510.

[0101] Figure 16 This is a block diagram of a charging dock 1400 according to an embodiment of the present disclosure. As shown, the charging dock 1400 may include a Hall effect sensor 1520, a control unit 1610, and output terminals 1420 and 1430. In this case, the output terminals 1420 and 1430 may be configured to be electrically connected to the input section of the battery of a wireless straightener.

[0102] In one embodiment, the control unit 1610 may include a soft-start circuit 1612 and an N-channel FET 1614. The control unit 1610 can control the external power applied to the output terminals 1420 and 1430. When the Hall effect sensor 1520 does not detect the magnetic force of the magnet 1510, the control unit 1610 can block the application of external power to the output terminals 1420 and 1430. This configuration prevents short circuits caused by short circuits at the output terminals 1420 and 1430. Conversely, when the Hall effect sensor 1520 detects the magnetic force of the magnet 1510, the control unit 1610 can gradually increase the amount of power applied to the output terminals 1420 and 1430 through the soft-start circuit 1612. This configuration prevents short circuits between the output terminals 1420 and 1430 and the first charging terminals 730 and 740 of the wireless straightener.
