Description

Technical Field

[0001] This invention relates to the field of hair styling equipment technology, and particularly to an adjustable-shape hair curling mechanism. This invention also relates to a hair curler. Background Technology

[0002] A curling iron is a common hair styling tool, mainly used to create wavy curls in hair.

[0003] The main components of a curling iron are the handle, base, and pressure plate. The pressure plate presses against the base plate to clamp the hair between them. Both the pressure plate and the base plate have heat-conducting plates that clamp and heat the hair. Because the two heat-conducting plates are not flat but wavy curved panels, straight hair can be styled into wavy curls after being clamped and heated for a certain period. The heat-conducting plates are designed with a circuit panel to control the temperature, and are generally made of tourmaline ceramic. This design evenly distributes heat, circulates heat, improves the hair protein structure to create curls, and protects the hair quality during the curling process.

[0004] Traditional curling irons have fixed-shape heating plates that cannot be changed after leaving the factory. They can only shape hair into a specific type of wave, resulting in a monotonous curling effect that is difficult to meet users' needs for different wave shapes.

[0005] In existing technologies, some hair curlers are designed with a series of heat-conducting plates of various sizes and wave shapes to achieve different curling wave shapes. These heat-conducting plates are mounted on the base and pressure cap using screws and other fasteners. When the curling wave shape needs to be changed, the current heat-conducting plate can simply be removed from the base and pressure cap, and a heat-conducting plate of a different size can be reinstalled. However, the disassembly and assembly of the heat-conducting plates is cumbersome. Users need to manually tighten multiple bolts and other fasteners, which is a lengthy and inconvenient process. To achieve a gradient wave curl, it is necessary to repeatedly disassemble and assemble heat-conducting plates of different sizes, resulting in a poor user experience.

[0006] Therefore, how to conveniently and efficiently achieve changes in the shape of curly hair waves, meet users' needs for different wavy curly hairstyles, and improve the user experience is a technical problem faced by those skilled in the art. Summary of the Invention

[0007] The purpose of this invention is to provide an adjustable-shape hair curling mechanism that can conveniently and efficiently achieve changes in the shape of curled waves, meeting users' needs for different wavy curl styles and improving the user experience. Another purpose of this invention is to provide a hair curler.

[0008] To solve the above-mentioned technical problems, the present invention provides an adjustable shape hair curling mechanism, including a base and a pressure cover rotatably connected to the base. The base is provided with a support heat-conducting plate for supporting hair strands, and the pressure cover is provided with a pressing heat-conducting plate for cooperating with the support heat-conducting plate to press the hair strands. The support heat-conducting plate includes a left support plate and a right support plate that can be closed into an arc shape, and the pressing heat-conducting plate includes a left pressing plate and a right pressing plate that can be closed into an arc shape. The distance between the left support plate and the right support plate and / or the distance between the left pressing plate and the right pressing plate is adjustable.

[0009] Preferably, it further includes an adjustment component disposed between the base and the pressure cover, for adjusting the distance between the left support plate and the right support plate and / or the distance between the left pressure plate and the right pressure plate.

[0010] Preferably, the left support plate and / or the right support plate are rotatably connected to the base; the left clamping plate and / or the right clamping plate are rotatably connected to the pressure cover.

[0011] Preferably, the left support plate and / or the right support plate are slidably connected to the base; the left clamping plate and / or the right clamping plate are slidably connected to the pressure cap.

[0012] Preferably, the adjustment assembly includes an operating part and an output end that forms a power connection and / or signal connection with the operating part. The operating part is used for users to perform adjustment operations, and the output end is used to drive the left support plate and the right support plate to rotate relative to each other, and / or to drive the left clamping plate and the right clamping plate to rotate relative to each other.

[0013] Preferably, the output end is rotatably mounted between the opposite sides of the left support plate and the right support plate, so that the left support plate and the right support plate can be driven to rotate relative to each other by the abutment of the output end at different circumferential positions.

[0014] Preferably, it further includes a first elastic element for driving the left support plate and the right support plate to rotate relative to each other to a reset position by elastic force, and a second elastic element for driving the left clamping plate and the right clamping plate to rotate relative to each other to a reset position by elastic force.

[0015] Preferably, the supporting heat-conducting plate further includes a first extended support plate and a second extended support plate respectively disposed on both sides of the base. The first extended support plate and the second extended support plate are both arc-shaped, and one end of the left support plate is rotatably connected to one end of the first extended support plate, and one end of the right support plate is rotatably connected to one end of the second extended support plate.

[0016] Preferably, the pressing heat-conducting plate further includes a first extended pressing plate and a second extended pressing plate respectively disposed on both sides of the pressing cover. The first extended pressing plate and the second extended pressing plate are both arc-shaped, and one end of the left pressing plate is rotatably connected to one end of the first extended pressing plate, and one end of the right pressing plate is rotatably connected to one end of the second extended pressing plate.

[0017] The present invention also provides a hair curler, including a handle and an adjustable shape curling mechanism connected to the handle, wherein the adjustable shape curling mechanism is specifically the adjustable shape curling mechanism described in any of the above claims.

[0018] The adjustable-shape hair curling mechanism provided by this invention mainly includes a base, a pressure cap, a supporting heat-conducting plate, and a pressing heat-conducting plate. The base is the main structure, and the pressure cap is connected to the base in a rotatable manner, allowing it to rotate relative to the base to achieve the opening and closing motion of the hair curler. The supporting heat-conducting plate is disposed on the base and is mainly used to support and heat the hair strands. The pressing heat-conducting plate is disposed on the pressure cap and is mainly used to cooperate with the supporting heat-conducting plate to press the hair strands together. Thus, when the pressure cap rotates to clamp with the base, the pressing heat-conducting plate simultaneously rotates to clamp with the supporting heat-conducting plate, thereby clamping the hair strands between the bottom surface of the pressing heat-conducting plate and the top surface of the supporting heat-conducting plate. Meanwhile, both the supporting heat-conducting plate and the pressing heat-conducting plate are separate structures. The supporting heat-conducting plate mainly includes a left supporting plate and a right supporting plate, while the pressing heat-conducting plate mainly includes a left pressing plate and a right pressing plate. The left and right supporting plates can be joined together to form an arc-shaped structure, and similarly, the left and right pressing plates can also be joined together to form an arc-shaped structure. This allows the arc-shaped structures formed by the left and right supporting plates to cooperate with the arc-shaped structures formed by the left and right pressing plates, clamping the hair strands between the two arc-shaped structures and bending them into an arc shape. This results in a specific wavy curl after heat setting. Importantly, the distance between the left and right supporting plates and / or the distance between the left and right pressing plates can be adjusted. Thus, by adjusting the distance between the left and right support plates, or the distance between the left and right clamping plates, or both simultaneously, the waveform width of the arc-shaped structure formed between the left and right support plates, and the waveform width of the arc-shaped structure formed between the left and right clamping plates, can be changed, thereby altering the shape of the curled hair waves formed when the hair is clamped between the two arc-shaped structures. Compared to existing technologies, the adjustable-shape curling mechanism provided by this invention eliminates the need to disassemble or reassemble the support heat-conducting plates or clamping heat-conducting plates. Simply adjusting the distance between the left and right support plates and / or the distance between the left and right clamping plates allows for convenient and efficient changes in the curled hair wave shape, meeting users' needs for different wavy curl styles and improving the user experience.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the overall structure of a specific embodiment of the present invention.

[0036] In one specific embodiment of the present invention, the adjustable shape curling mechanism mainly includes a base 1, a pressure cover 2, a supporting heat-conducting plate 3, and a pressing heat-conducting plate 4.

[0037] The base 1 is the main structure, and the pressure cover 2 is connected to the base 1 and forms a rotatable connection, which can rotate relative to the base 1 to realize the opening and closing movement of the curling iron.

[0038] The supporting heat-conducting plate 3 is mounted on the base 1 and is mainly used to support and heat the hair strands. The pressing heat-conducting plate 4 is mounted on the pressure plate 2 and is mainly used to cooperate with the supporting heat-conducting plate 3 to press the hair strands together. Thus, when the pressure plate 2 is flipped to clamp with the base 1, the pressing heat-conducting plate 4 is also flipped to clamp with the supporting heat-conducting plate 3, thereby clamping the hair strands between the bottom surface of the pressing heat-conducting plate 4 and the top surface of the supporting heat-conducting plate 3.

[0039] Meanwhile, both the supporting heat-conducting plate 3 and the pressing heat-conducting plate 4 are split structures. The supporting heat-conducting plate 3 mainly includes a left supporting plate 31 and a right supporting plate 32, and the pressing heat-conducting plate 4 mainly includes a left pressing plate 41 and a right pressing plate 42. The left supporting plate 31 and the right supporting plate 32 can be closed from left to right to form an arc-shaped structure. Similarly, the left pressing plate 41 and the right pressing plate 42 can also be closed from left to right to form an arc-shaped structure. This allows the arc-shaped structure formed by the left supporting plate 31 and the right supporting plate 32 to cooperate with the arc-shaped structure formed by the left pressing plate 41 and the right pressing plate 42, clamping the hair between the two arc-shaped structures and bending it into an arc shape, thereby forming a specific shaped wave after heating and shaping.

[0040] Importantly, the distance between the left support plate 31 and the right support plate 32 can be adjusted, and / or the distance between the left clamping plate 41 and the right clamping plate 42 can be adjusted. Thus, by adjusting the distance between the left support plate 31 and the right support plate 32, or the distance between the left clamping plate 41 and the right clamping plate 42, or both simultaneously, the waveform width of the arc-shaped structure formed between the left support plate 31 and the right support plate 32, and the waveform width of the arc-shaped structure formed between the left clamping plate 41 and the right clamping plate 42, can be changed, thereby altering the shape of the curls formed when the hair is clamped between the two arc-shaped structures.

[0041] like Figure 7 , Figure 8 As shown, Figure 7 This is a schematic diagram showing a clamping state of hair strands between the supporting heat-conducting plate 3 and the pressing heat-conducting plate 4. Figure 8 This is a schematic diagram of another clamping state of the hair between the supporting heat-conducting plate 3 and the pressing heat-conducting plate 4.

[0042] Compared to existing technologies, the adjustable-shape hair curling mechanism provided in this embodiment does not require disassembly or assembly of the support heat-conducting plate 3 or the pressing heat-conducting plate 4. It only requires adjusting the distance between the left support plate 31 and the right support plate 32 and / or the distance between the left pressing plate 41 and the right pressing plate 42 to conveniently and efficiently achieve changes in the shape of the curling waves, meet the user's needs for different wavy curling styles, and improve the user experience.

[0043] like Figure 9 , Figure 10 , Figure 11 As shown, Figure 9 This is a diagram illustrating the first wave shape after hair has been styled. Figure 10 This is a diagram illustrating the second wave shape after hair has been styled. Figure 11 This is a diagram illustrating the third wave shape after the hair has been styled.

[0044] It should be noted that when the distance between the left support plate 31 and the right support plate 32 increases, the hair strands located between them can still maintain a certain arc shape by relying on the support of the top of the left support plate 31 and the right support plate 32 and the toughness of the hair strands themselves. Although they cannot form sharp "peaks" or "troughs", they still have a relatively gentle wave shape overall. Furthermore, the change in the distance between the left support plate 31 and the right support plate 32 specifically refers to the change in the horizontal distance between two corresponding reference points on any horizontal plane on their opposite sides. Clearly, when the distance changes through relative sliding, the change in distance between the two reference points on any horizontal plane is synchronous and equal. However, when the distance changes through relative rotation, the change in distance between the two reference points on different horizontal planes is obviously different, specifically related to the radial distance from the reference point to their respective rotation axes. The larger the radial distance, the greater the distance change, and vice versa, until it becomes zero, i.e., at the position of their rotation axes, the distance change is also zero. This is equivalent to adjusting the distance only at the non-rotation axis positions of the left support plate 31 and the right support plate 32. The change in the distance between the left clamping plate 41 and the right clamping plate 42 is similar.

[0045] like Figure 2 As shown, Figure 2 for Figure 1 A partial structural diagram.

[0046] In one embodiment, to facilitate the adjustment of the distance between the left support plate 31 and the right support plate 32, the left support plate 31 is rotatably connected to the base plate, and the right support plate 32 is also rotatably connected to the base plate. With this configuration, the distance between the left and right support plates can be adjusted by their relative rotation. Of course, if one of the left support plate 31 and the right support plate 32 remains fixed while only the other can rotate, the distance can also be adjusted. When both the left support plate 31 and the right support plate 32 can rotate, they can rotate synchronously in opposite directions to symmetrically control the specific shape of the arc-shaped structure between them.

[0047] Accordingly, to facilitate the adjustment of the distance between the left pressing plate 41 and the right pressing plate 42, in this embodiment, the left pressing plate 41 is rotatably connected to the pressure cover 2, and the right pressing plate is also rotatably connected to the pressure cover 2. With this configuration, the distance between the left pressing plate 41 and the right pressing plate 42 can be adjusted by relative rotation. Of course, if one of the left pressing plate 41 and the right pressing plate 42 remains fixed, and only the other can rotate, the distance between them can also be adjusted. When both the left pressing plate 41 and the right pressing plate 42 can rotate, they can rotate synchronously in opposite directions to symmetrically control the specific shape of the arc-shaped structure between them.

[0048] like Figure 3 As shown, Figure 3 for Figure 2 Exploded view of the structure.

[0049] Generally, to facilitate the rotational connection between the left support plate 31, the right support plate 32, and the base 1, this embodiment also adds a first extended support plate 33 and a second extended support plate 34 to the support heat-conducting plate 3. The first extended support plate 33 is disposed on the surface of the base 1, typically located on the left side of the base 1, in the same area as the left support plate 31. The first extended support plate 33 is an arc-shaped or wave-shaped plate, with one end connected to one end of the left support plate 31, forming a rotational connection. Specifically, a rotating groove can be formed on the end of the first extended support plate 33, and a rotating shaft 8 can be installed in the rotating groove. One end of the left support plate 31 is then fitted onto the rotating shaft 8. The rotation of the rotating shaft 8 within the rotating groove allows for the rotational adjustment of the left support plate 31 relative to the first extended support plate 33. Simultaneously, the first extended support plate 33 is equivalent to the left extension of the left support plate 31; both are arc-shaped, and their bending directions can be opposite to form a wave shape with both "crests" and "troughs."

[0050] Similarly, the second extended support plate 34 is disposed on the surface of the base 1, typically located on the right side of the base 1, in the same area as the right support plate 32. The second extended support plate 34 is an arc-shaped or wave-shaped plate, with one end connected to one end of the right support plate 32, forming a rotatable connection. Specifically, a rotating groove can be formed on the end of the second extended support plate 34, and a rotating shaft 8 can be installed in the rotating groove. One end of the right support plate 32 is then fitted onto the rotating shaft 8. The rotation of the rotating shaft 8 within the rotating groove allows for the rotational adjustment of the right support plate 32 relative to the second extended support plate 34. Simultaneously, the second extended support plate 34 is equivalent to the right-side extension of the right support plate 32; both are arc-shaped, and their bending directions can be opposite to form a wave shape with both "crests" and "troughs."

[0051] Based on the same consideration, to facilitate the rotational connection between the left pressing plate 41, the right pressing plate 42, and the pressure cover 2, this embodiment also adds a first extended pressing plate 43 and a second extended pressing plate 44 to the pressing heat-conducting plate 4. The first extended pressing plate 43 is disposed on the bottom surface of the pressure cover 2, typically located on the left side of the pressure cover 2, in the same area as the left pressing plate 41. The first extended pressing plate 43 is an arc-shaped or wavy plate, with one end connected to one end of the left pressing plate 41, forming a rotational connection. Specifically, a rotating groove can be formed on the end of the first extended pressing plate 43, and a rotating shaft 8 can be installed in the rotating groove. One end of the left pressing plate 41 is then fitted onto the rotating shaft 8. The rotation of the rotating shaft 8 within the rotating groove allows for the adjustment of the rotation of the left pressing plate 41 relative to the first extended pressing plate 43. Meanwhile, the first extended pressing plate 43 is equivalent to the left extension of the left pressing plate 41. Both are arc-shaped and can be bent in opposite directions to form a wave shape with both "crests" and "troughs".

[0052] Similarly, the second extended pressing plate 44 is disposed on the bottom surface of the pressure cover 2, usually located on the right side of the pressure cover 2, in the same area as the right pressing plate 42. The second extended pressing plate 44 is an arc-shaped or wavy plate, with one end connected to one end of the right pressing plate 42, forming a rotatable connection. Specifically, a rotating groove can be formed on the end of the second extended pressing plate 44, and a rotating shaft 8 can be installed in the rotating groove. One end of the right pressing plate 42 is then fitted onto the rotating shaft 8. The rotation of the rotating shaft 8 within the rotating groove allows for the adjustment of the right pressing plate 42 relative to the second extended pressing plate 44. Simultaneously, the second extended pressing plate 44 is equivalent to the right-side extension of the right pressing plate 42. Both are arc-shaped, and their bending directions can be opposite to form a wavy shape with both "crests" and "troughs."

[0053] Of course, to facilitate the creation of rotating grooves on the first extended pressing plate 43 and the second extended pressing plate 44, the first extended pressing plate 43 and the second extended pressing plate 44 can be cylindrical, so that rotating grooves can be created on the outer wall of the cylinder. At the same time, to facilitate the installation of the rotating shaft 8, mounting sleeves can be protruding on the non-contact surfaces (i.e., not in contact with hair) at the bottom ends of the left support plate 31, the right support plate 32, the left pressing plate 41, and the right pressing plate 42, so that the rotating shaft 8 can be installed through the mounting sleeves.

[0054] In another embodiment, to facilitate the adjustment of the distance between the left support plate 31 and the right support plate 32, the left support plate 31 is slidably connected to the base plate, and the right support plate 32 is also slidably connected to the base plate. With this configuration, the distance between the left and right support plates can be adjusted by their relative sliding. Of course, if one of the left support plate 31 and the right support plate 32 remains fixed while only the other can slide, the distance adjustment can also be achieved. When both the left support plate 31 and the right support plate 32 can slide, they can slide synchronously, such as towards each other or away from each other, to symmetrically control the specific shape of the arc-shaped structure between them.

[0055] Accordingly, to facilitate the adjustment of the distance between the left pressing plate 41 and the right pressing plate 42, in this embodiment, the left pressing plate 41 is slidably connected to the pressure cover 2, and the right pressing plate is also slidably connected to the pressure cover 2. With this configuration, the distance between the left pressing plate 41 and the right pressing plate 42 can be adjusted by relative sliding between them. Of course, if one of the left pressing plate 41 and the right pressing plate 42 remains fixed, while only the other can slide, the distance between them can also be adjusted. When both the left pressing plate 41 and the right pressing plate 42 can slide, they can slide synchronously, such as sliding towards each other or backwards, to symmetrically control the specific shape of the arc structure between them.

[0056] like Figure 4 As shown, Figure 4 for Figure 2 A partial structural diagram from another perspective.

[0057] To facilitate the adjustment of the distance between the left support plate 31 and the right support plate 32, and / or the distance between the left clamping plate 41 and the right clamping plate 42, an adjustment component 5 is added in this embodiment. Specifically, the adjustment component 5 is disposed between the base 1 and the pressure cover 2, and mainly includes an operating part 51 and an output end 52. The operating part 51 is mainly used for user adjustment operations, while the output end 52 forms a power connection and / or signal connection with the operating part 51, and is mainly used as an actuator: for the distance adjustment method achieved by the aforementioned relative rotation, the output end 52 is mainly used to drive the left support plate 31 and the right support plate 32, and the left clamping plate 41 and the right clamping plate 42 to rotate relative to each other; for the distance adjustment method achieved by the aforementioned relative sliding method, the output end 52 is mainly used to drive the left support plate 31 and the right support plate 32, and the left clamping plate 41 and the right clamping plate 42 to slide relative to each other.

[0058] The following is a detailed explanation using the example of the output end 52 being used to drive the left support plate 31 and the right support plate 32, and the left clamping plate 41 and the right clamping plate 42 to rotate relative to each other.

[0059] like Figure 5 , Figure 6 As shown, Figure 5 This is a schematic diagram of one adjustment state of the adjustment component 5. Figure 6 This is a schematic diagram of another adjustment state of the adjustment component 5.

[0060] In this embodiment, the output end 52 is specifically installed between the opposite sides of the left support plate 31 and the right support plate 32, and can rotate under the drive of the operating part 51. The cross-section of the output end 52 is non-circular, meaning that the radial distances at various points are not always equal during one rotation, and there are usually multiple unequal distances. For example, the output end 52 can be shaft-mounted, rod-shaped, columnar, or block-shaped, and its cross-sectional shape can be rectangular, elliptical, triangular, trapezoidal, etc. When the output end 52 rotates, the opposite sides of the left support plate 31 and the right support plate 32 will respectively abut against different positions on the outer edge of the output end 52, thereby driving the left support plate 31 and the right support plate 32 to rotate accordingly, thus adjusting the included angle and distance between them. With this configuration, the output end 52 will form different abutment states against the left support plate 31 and the right support plate 32 at different rotation angle positions, achieving different included angles and distances between them.

[0061] Meanwhile, since the pressure cap 2 needs to be pressed tightly against the base 1, when the pressure cap 2 is pressed down, the left pressure plate 41 will be subjected to the abutting force of the left support plate 31, and the right pressure plate 42 will be subjected to the abutting force of the right support plate 32. Therefore, under the combined action of the abutting force and gravity, the left pressure plate 41 and the right pressure plate 42 can automatically rotate and adjust to the target angle position without the need for active adjustment by the output end 52, so as to match the left support plate 31 and the right support plate 32 and clamp the hair.

[0062] Of course, an additional output terminal 52 can also be provided, which is dedicated to driving the left clamping plate 41 and / or the right clamping plate 42 to rotate.

[0063] As for the operating unit 51, the operating unit 51 may specifically adopt components that form a power connection with the output end 52, such as a rotating rod, adjusting bolt, gear, etc., or components that form a signal connection with the output end 52, such as a knob, button, control panel, etc., or components that form both a power connection and a signal connection with the output end 52, such as a drive motor.

[0064] Furthermore, to ensure that the left support plate 31 and right support plate 32 automatically return to their initial state after the curling operation, a first elastic element 6 is added in this embodiment. Specifically, the first elastic element 6 is mainly installed on the rotating shaft 8 of the left support plate 31 and right support plate 32, for example, in the form of a coil spring, and is wound around the end of the rotating shaft 8. It is mainly used to generate elastic deformation when the rotating shaft 8 of the left support plate 31 and right support plate 32 rotates, and after the output end 52 stops driving the left support plate 31 and right support plate 32, it uses the elastic force to drive the rotating shaft 8 to rotate in the opposite direction, thereby driving the left support plate 31 and right support plate 32 to rotate synchronously in the opposite direction until they return to their initial position (generally, the top ends of the left support plate 31 and right support plate 32 are in contact with each other, at which time the distance between them is the smallest).

[0065] Of course, the first elastic element 6 can also be a helical spring, and connected between the opposite sides of the left support plate 31 and the right support plate 32.

[0066] Similarly, in order to enable the left and right pressure plates 41 and 42 to automatically return to their initial state after the curling operation is completed, a second elastic element 7 is added in this embodiment. Specifically, the second elastic element 7 is mainly installed on the rotating shaft 8 of the left and right pressure plates 41 and 42, for example, in the form of a coil spring, and is wound around the end of the rotating shaft 8. It is mainly used to generate elastic deformation when the rotating shaft 8 of the left and right pressure plates 41 and 42 rotates, and after the output end 52 stops driving the left and right pressure plates 41 and 42 or after the pressure cover 2 is opened, the elastic force drives the rotating shaft 8 to rotate in the opposite direction, thereby driving the left and right pressure plates 41 and 42 to rotate synchronously in the opposite direction until they return to their initial position.

[0067] In addition, heating elements, such as PTC ceramic heaters, are installed on both the left support plate 31 and the right support plate 32. These heaters are specifically installed on the opposite sides of the left and right support plates 31 and 32, i.e., on the non-contact surfaces that do not come into contact with the hair. To facilitate the installation of the heaters, mounting grooves 35 are also provided on the opposite sides of both the left and right support plates 31 and 32 in this embodiment, allowing the heaters to be installed within them. This arrangement positions the heaters closer to the top of the left and right support plates 31 and 32, enabling heat to be transferred more quickly to the "crests" or "troughs" of the hair, resulting in more stable and efficient wave styling.

[0068] Of course, the heater can also be installed on the non-contact surfaces of the left and right clamping plates 41 and 42 that do not come into contact with the hair.

[0069] This embodiment also provides a hair curler, which mainly includes a handle and an adjustable shape curling mechanism connected to the handle. The specific details of the adjustable shape curling mechanism are the same as those described above, and will not be repeated here.

[0070] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
