Description

Technical Field

[0001] This invention relates to the field of hair styling equipment technology, and in particular to a hair curler. Background Technology

[0002] Existing curling irons typically include a heated curling barrel for wrapping hair around to create curls. Commercially available curling irons generally have a fixed barrel diameter; different models correspond to different diameters, and users must choose the appropriate size based on the desired curl size. However, in practice, hairstyles often require creating multiple sizes of curls on the same hair surface, such as a combination of large waves and tight curls. To achieve this, users usually need multiple curling irons with different barrel diameters and repeatedly switch between them during use. Summary of the Invention

[0003] The main objective of this invention is to provide a hair curler that can have different outer diameters to meet diverse hair curling needs.

[0004] To achieve the above objectives, the present invention provides a hair curler comprising: A hair curling tube includes a first clamp, a second clamp, and a curling plate. The first clamp and the second clamp cooperate to clamp hair, and the curling plate is movably mounted on the outer side of the first clamp. A driving mechanism includes a driving member that is slidably engaged with the hair curling movable plate. The driving member is capable of moving along the axial direction of the hair curling cylinder to drive the hair curling movable plate to move in a direction perpendicular to the axial direction of the hair curling cylinder.

[0005] In one embodiment, the hair-curling movable plate has a first inclined surface on the side facing the first clamping member, and the driving member has a second inclined surface on the side facing the hair-curling movable plate. The first inclined surface and the second inclined surface are slidably engaged so that the hair-curling movable plate can move along the direction perpendicular to the axial direction of the hair-curling cylinder.

[0006] In one embodiment, the hair curling plate is further provided with a first abutting surface that intersects and connects with the first inclined surface, and the driving member is further provided with a second abutting surface that intersects and connects with the second inclined surface. The first abutting surface and the second abutting surface are abutted and adapted to each other so that the hair curling plate is kept at a position away from the axis of the hair curling tube.

[0007] In one embodiment, the driving mechanism further includes a pusher and a transmission link mounted on the curling cylinder, one end of the transmission link being rotatably connected to the driving member and the other end being rotatably connected to the pusher.

[0008] In one embodiment, the curling plate is movably mounted on the outer side of the second clamping member.

[0009] In one embodiment, the first clamping member is configured as a movable clamping plate, and the second clamping member is configured as a fixed clamping plate, wherein the movable clamping plate is rotatable relative to the fixed clamping plate.

[0010] In one embodiment, when the movable curling plate is held close to the axis of the curling barrel, a first gap is formed between the first inclined surface and the second inclined surface of the movable clamping plate, and a second gap is formed between the first inclined surface and the second inclined surface of the fixed clamping plate. The width of the first gap in the axial direction of the curling barrel is greater than the width of the second gap in the axial direction of the curling barrel.

[0011] In one embodiment, both the first clamping member and the second clamping member are provided with the driving member. The driving member of the first clamping member is connected to the pushing member through the transmission link, and the driving member of the second clamping member is integrally formed with the pushing member.

[0012] In one embodiment, the fixed clamp includes a clamp body, one end of which is provided with a gripping part, and an installation cavity is formed in the gripping part. The movable clamp is provided with a pressing part at one end near the gripping part, and the pressing part is rotatably connected to the gripping part through a rotating part.

[0013] In one embodiment, the pressing part is provided with a clearance opening for avoiding the pushing member and the transmission link, and the pressing part is provided with a third inclined surface on the side facing the gripping part, and a clearance space is formed between the third inclined surface and the inner wall surface of the mounting cavity; when the pressing part moves in the direction toward the axis of the curling tube under the action of external force, it drives the movable clamp to rotate around the rotating part, so that the movable clamp unfolds relative to the fixed clamp.

[0014] In one embodiment, the clamp body of the fixing clamp is integrally formed with the gripping part.

[0015] In one embodiment, the driving mechanism further includes a power source mounted on the curling cylinder. The power source is located on the side of the push member away from the transmission link and is connected to the push member via the transmission link to drive the drive member to move axially along the curling cylinder.

[0016] In one embodiment, the first clamping member and / or the second clamping member further includes a fixed mounting bracket, the pushing member is provided with a mounting groove on the side facing the driving member, the curling iron further includes a fan installed in the mounting groove, the pushing member is provided with an air inlet communicating with the mounting groove and the external space, and the curling movable plate and / or the fixed mounting bracket is provided with an air outlet.

[0017] In one embodiment, the first clamping member includes a clamping plate body, a fixed mounting bracket, and a resetting member. The fixed mounting bracket and the corresponding clamping plate body together define a receiving cavity. The fixed mounting bracket has a receiving groove communicating with the receiving cavity, and the hair curling movable plate is movably disposed in the receiving groove. The resetting member is disposed in the receiving cavity and connects the fixed mounting bracket and the hair curling movable plate, and is used to apply a driving force to the hair curling movable plate to move in the direction of the hair curling cylinder axis.

[0018] In one embodiment, the hair curling plate has a connecting post on the side facing the main body of the clamp, the fixed mounting bracket has a connecting hole for the connecting post to pass through, the reset member is configured as an elastic member, the elastic member is sleeved on the outer periphery of the connecting post, one end is connected to the connecting post, and the other end abuts against the outer edge of the connecting hole.

[0019] In one embodiment, the fixed mounting bracket is provided with a receiving groove for accommodating the hair curling movable plate, and there are multiple hair curling movable plates, which are distributed at intervals along the circumference of the hair curling tube.

[0020] The technical solution of this invention utilizes a drive component that slides along the axial direction of the curling barrel to engage with a movable curling plate, thereby driving the movable curling plate to move in a direction perpendicular to the axial direction of the curling barrel. This alters the effective outer diameter of the curling barrel, allowing for flexible adjustment of the curl size without changing equipment during a single styling session. This satisfies diverse curling needs, such as large waves and tight curls. Furthermore, it eliminates the need for repeated machine stops, removal of old curling barrels, and replacement with new ones during the styling process, shortening hair styling time, reducing operational complexity, and improving styling efficiency. Additionally, by avoiding frequent equipment switching, the temperature of the curling barrel remains consistently high, enhancing the hair styling effect. Attached Figure Description

[0028] This invention proposes a hair curler.

[0029] Please see Figures 1 to 7 In one embodiment of the present invention, the hair curler includes a curling barrel and a driving mechanism. The curling barrel includes a first clamping member, a second clamping member, and a curling movable plate 120. The first clamping member and the second clamping member cooperate to clamp hair. The curling movable plate 120 is movably mounted on the outer side of the first clamping member. The driving mechanism includes a driving member 200, which is slidably engaged with the curling movable plate 120. The driving member 200 can move along the axial direction of the curling barrel to drive the curling movable plate 120 to move in a direction perpendicular to the axial direction of the curling barrel.

[0030] Specifically, the hair curler includes a curling barrel and a drive mechanism. The curling barrel is generally cylindrical and may include a first clamping member and a second clamping member arranged opposite each other in a semi-circular shape, symmetrically arranged along the central axis of the curling barrel. A curling movable plate 120 is provided on the outer side of the first clamping member, and a clamping space for accommodating hair is formed between the opposing inner surfaces of the first and second clamping members. The outer side of the first and second clamping members refers to the side away from the central axis of the curling barrel; correspondingly, the inner side refers to the side closer to the central axis.

[0031] The curling plate 120 is a movable part. The driving mechanism includes a driving component 200, which is slidably engaged with the curling plate 120. The driving component 200 can move along the axial direction of the curling cylinder to drive the curling plate 120 to move in a direction perpendicular to the axial direction of the curling cylinder (i.e., the radial direction of the curling cylinder). The driving method for the axial movement of the driving component 200 can be manual, such as by including an operating lever in the driving mechanism, which is linked to the driving component 200, allowing the user to drive the axial displacement of the driving component 200 by pressing or rotating the operating lever; alternatively, it can be driven by a motor, such as by including a micro motor and a lead screw in the driving mechanism, with the lead screw threadedly connected to the driving component 200, and the motor driving the lead screw to rotate to drive the axial movement of the driving component 200.

[0032] When the drive member 200 moves axially, the curling movable plate 120 moves outward or inward along the axis perpendicular to the curling barrel, thereby changing the distance of the curling movable plate 120 relative to the central axis of the curling barrel. The curling movable plate 120 is disposed on the outer wall of the first clamping member, and its radial displacement can change the effective winding outer diameter of the entire curling barrel. For example, if the curling movable plate 120 needs to move outward, it is pushed on the first clamping member to move outward in the direction perpendicular to the axis of the curling barrel, thereby increasing the effective outer diameter of the hair winding and forming large wavy curls; when the curling movable plate moves inward or returns to its original position, the effective winding outer diameter decreases, forming tight small curls. By controlling the axial displacement of the drive member 200, the stepless adjustment or multi-level fixed diameter adjustment of the curling barrel outer diameter can be achieved.

[0033] Thus, when the drive unit 200 moves along the axial direction of the curling barrel, it drives the curling movable plate 120 to move in a direction perpendicular to the axial direction of the curling barrel through sliding engagement, thereby changing the effective outer diameter of the curling barrel. This allows for flexible adjustment of the curl size without changing equipment during a single styling process, meeting diverse curling needs such as large waves and tight small curls. At the same time, there is no need to repeatedly stop the machine, remove the old curling barrel, and replace it with a new one during the styling process, shortening the hair styling time, reducing operational complexity, and improving styling efficiency. In addition, by avoiding frequent equipment switching, the temperature of the curling barrel can be kept constant, improving the hair styling effect.

[0034] In one implementation, please refer to Figures 3 to 7 The hair curling plate 120 has a first inclined surface 121 on the side facing the first clamping member, and the driving member 200 has a second inclined surface 210 on the side facing the hair curling plate 120. The first inclined surface 121 and the second inclined surface 210 are slidably engaged so that the hair curling plate 120 can move in a direction perpendicular to the axial direction of the hair curling tube.

[0035] The curling plate 120 has a first inclined surface 121 on the side facing the first clamping member, while the driving member 200 has a second inclined surface 210 on the side facing the curling plate 120. The first inclined surface 121 and the second inclined surface 210 are slidably engaged. The curling plate 120 is movably mounted on the first clamping member. When the driving member 200 moves along the axial direction of the curling barrel, the second inclined surface 210 on the driving member 200 and the first inclined surface 121 on the curling plate 120 come into contact and slide. Since the normal direction of the inclined surface forms an angle with the axial direction, the force exerted by the driving member 200 on the curling plate 120 can be decomposed into an axial component and a radial component. The radial component drives the curling plate 120 to move outward in a direction perpendicular to the axis of the curling barrel, thereby changing the effective outer diameter of the curling barrel. In this way, the outer diameter of the curling barrel can be controlled to meet different sizes of curling effects, thus satisfying diverse curling needs.

[0036] For example, when a user needs to increase the effective outer diameter of the curling barrel to create larger waves, the drive mechanism (e.g., pressing the handle, rotating the adjustment knob, or starting the micro motor) can be used to move the drive member 200 along the axial direction of the curling barrel. As the drive member 200 moves axially, the first inclined surface 121 and the second inclined surface 210 slide against each other. The axial displacement of the drive member 200 is converted into a radial thrust on the curling movable plate 120 through the sliding contact between the two inclined surfaces, thereby pushing the curling movable plate 120 to move outward in a direction perpendicular to the axial direction of the curling barrel, so that the outer contour of the entire curling barrel expands outward, and the effective outer diameter of the curling barrel increases accordingly.

[0037] Conversely, when the user wishes to restore a smaller curl outer diameter or reset the curler after styling, the drive mechanism can be reversed, causing the drive component 200 to retract axially. At this time, the curling plate 120 returns to its initial position, and the curling tube restores its original outer diameter. The entire adjustment process requires no disassembly or replacement of parts, making it simple to operate and quick to respond.

[0038] The structural design of the first inclined surface 121 and the second inclined surface 210 converts the axial linear motion of the driving component 200 into the displacement of the hair curling movable plate 120 in a direction perpendicular to the axis of the hair curling barrel. The transmission path is simple and direct, reducing manufacturing costs and assembly complexity. Moreover, the large contact area of ​​the inclined surfaces helps to ensure the stability of the hair curling movable plate 120 during movement. At the same time, the self-locking characteristic of the inclined surfaces can prevent the hair curling movable plate 120 from accidentally retracting when the hair is curled, thus improving the stability and reliability of the outer diameter of the hair curling barrel during the styling process.

[0039] In one embodiment, a multi-level positioning structure (such as a slot and elastic protrusion) can be integrated into the drive component 200 to enable the curling tube to be stably locked at several preset outer diameter settings (such as 25mm, 32mm, and 38mm), meeting the curling precision requirements of different hairstyle designs and improving the user experience. That is, by controlling the axial stroke of the drive component 200, the curling tube can have different outer diameters, thereby creating different curling effects during the styling process. This allows for the flexible creation of curling effects of different sizes within the same styling process, satisfying diverse curling needs.

[0040] The driving component 200 can be an arc-shaped plate, with the bending direction of the arc-shaped plate being the same as the circumferential direction of the hair curling cylinder; the driving component 200 can also be multiple flat plates spaced apart along the axial direction of the hair curling cylinder.

[0041] In other embodiments, the drive member 200 can be designed as a tapered core rod or a tapered sleeve, with its outer circumferential surface being a smooth tapered surface. A matching tapered abutment surface is provided on the inner side of the curling movable plate 120, with the two tapered directions opposite. When the drive member 200 advances axially, the tapered surface gradually wedges into the inner side of the curling movable plate 120, using the normal component of the tapered surface to push the curling movable plate 120 outwards; when the drive member 200 retracts axially, the curling movable plate 120 can fall back radially.

[0042] In one implementation, please refer to Figures 3 to 7 The hair curling plate 120 is also provided with a first abutting surface 122 that intersects and connects with the first inclined surface 121, and the driving member 200 is also provided with a second abutting surface 220 that intersects and connects with the second inclined surface 210. The first abutting surface 122 and the second abutting surface 220 abut and adapt to each other so that the hair curling plate 120 is kept away from the axis of the hair curling tube.

[0043] The inner side of the curling plate 120 may be provided with a first push block, which has a first abutting surface 122 and a first inclined surface 121 connecting the first abutting surface 122 with the inner side of the curling plate 120. Correspondingly, the drive member 200 may be provided with a second push block, which has a second inclined surface 210 and a second inclined surface 210 connecting the second inclined surface 210 with the drive member 200.

[0044] Please see Figure 7 When the driving member 200 moves axially and slides through the first inclined surface 121 and the second inclined surface 210, the first abutting surface 122 abuts against the second abutting surface 220. The force applied by the driving member 200 is no longer transmitted through the inclined surfaces, but is supported by the direct contact of the two abutting surfaces. Thus, when hair is wrapped around the outside of the curling plate 120 and generates pressure inward perpendicular to the axis of the curling tube, the direction of this pressure acting on the abutting surface is basically consistent with the normal direction of the abutting surface, and the curling plate 120 can be reliably held in a position away from the axis of the curling tube. Even if the curling plate 120 is subjected to slight radial pressure due to vibration or accidental contact during the styling process, it will not cause the curling plate 120 to retract unexpectedly, ensuring the stability and consistency of the outer diameter of the curling tube throughout the heating and winding process, thereby improving the uniformity and repeatability of the curling.

[0045] In one implementation, please refer to Figure 6 , Figure 7 and Figure 11 The drive mechanism also includes a pusher 300 and a transmission link 400 mounted on the curling tube. One end of the transmission link 400 is rotatably connected to the drive member 200, and the other end is rotatably connected to the pusher 300.

[0046] The first and second clamping members can be rotatably connected via a pivot, hinge, or pivot structure, allowing the first clamping member to open or close relative to the second clamping member for easy insertion or removal of hair. The pusher 300 can move axially along the curling cylinder under external force and synchronously moves the drive member 200 via a transmission link 400. One end of the transmission link 400 is hinged to the pusher 300, and the other end is hinged to the drive member 200. The transmission link 400 is a rigid structure with hinge holes at both ends, and can be connected to the pusher 300 and the movable drive member 200 via pins or ball joints, allowing it to swing to accommodate the opening and closing of the first and second clamping members. When the first and second clamping members are rotatably opened, the pusher 300 remains stationary in the axial direction, and the transmission link 400 drives the drive member 200 of the first clamping member to rotate synchronously.

[0047] In one implementation, please refer to Figure 7 and Figure 11 A hair curling plate 120 is movably mounted on the outer side of the second clamping member.

[0048] The second clamping member is disposed opposite to and cooperates with the first clamping member to clamp the hair. A curling plate 120 is movably mounted on the outer side of both the first and second clamping members. Referring to the above, the driving member 200 can form a sliding engagement with the curling plate 120 located on the outer side of the second clamping member. For example, a first inclined surface 121 is provided on the side of the curling plate 120 facing the second clamping member, and a second inclined surface 210 is provided on the corresponding side of the driving member 200. This sliding engagement allows the axial movement of the driving member 200 to drive the radial movement of the curling plate 120.

[0049] When the drive member 200 moves along the axial direction of the curling barrel, its motion is transmitted to the curling movable plate 120 on the outer side of the second clamping member through the mating structure. This drives the curling movable plate 120 to move outward or inward in a direction perpendicular to the axis of the curling barrel (i.e., radially), thereby changing the effective outer contour of the curling barrel on that side. Positioning the curling movable plate 120 on the outer side of the second clamping member is functionally equivalent to positioning it on the outer side of the first clamping member, achieving the same adjustability of the curling barrel's outer diameter. The curling movable plate 120 is also movably mounted on the outer side of the second clamping member, adapting to different operating habits or styling needs. Users can drive only the curling movable plate 120 on the first clamping member side radially, or only the curling movable plate 120 on the second clamping member side radially, or simultaneously drive both sides radially, further enhancing the product's flexibility.

[0050] In one implementation, please refer to Figure 1 and Figure 2 The first clamping member is configured as a movable clamping plate 100b, and the second clamping member is configured as a fixed clamping plate 100a. The movable clamping plate 100b can rotate relative to the fixed clamping plate 100a.

[0051] The first clamping element is configured as a movable clamping plate 100b, and the second clamping element is configured as a fixed clamping plate 100a. The movable clamping plate 100b can rotate relative to the fixed clamping plate 100a around a pivot axis via a pivot shaft or hinge structure. The movable clamping plate 100b can open at a certain angle relative to the fixed clamping plate 100a, so that the user can place the hair strand to be styled into the clamping space between the fixed clamping plate 100a and the movable clamping plate 100b. When the movable clamping plate 100b rotates toward the fixed clamping plate 100a and presses together, both clamp the hair strand and ensure that the hair strand is stably attached to the surface of the curling tube during the curling process without relative slippage. Setting the first clamping element as a movable clamping plate 100b makes the clamping operation more convenient and flexible. The user only needs to hold the curling iron with one hand and control the opening and closing of the movable clamping plate 100b by pressing or releasing the operating part. The insertion and clamping of the hair strand can be completed with one hand, making the operation intuitive and effortless.

[0052] The rotation of the movable clamping plate 100b and the radial movement of the curling movable plate 120 are two independent movements. The former is a circumferential opening and closing movement used to achieve the clamping function; the latter is a radial displacement movement used to achieve the outer diameter adjustment function. The two do not interfere with each other and work together to ensure the reliability of clamping while also having the ability to flexibly adjust the outer diameter of the curling tube.

[0053] In one implementation, please refer to Figure 4 When the hair curling plate 120 is held close to the axis of the hair curling tube (in the unraised state), a first gap is formed between the first inclined surface 121 and the second inclined surface 210 of the movable clamping plate 100b, and a second gap is formed between the first inclined surface 121 and the second inclined surface 210 of the fixed clamping plate 100a. The width of the first gap in the axial direction of the hair curling tube is greater than the width of the second gap in the axial direction of the hair curling tube.

[0054] The curling plate 120 is normally held in its initial position near the axis of the curling cylinder (i.e., the curling plate 120 is not raised). In this state, the first inclined surface 121 located on the inner side of the curling plate 120 does not contact the second inclined surface 210 located on the drive member 200, and there is a first gap between them. When no external driving force is applied, there is no mechanical coupling between the first inclined surface 121 and the second inclined surface 210, and they are in a non-contact state. Only when the user actively operates the drive mechanism to move the drive member 200 axially to a certain stroke will the second inclined surface 210 contact and push against the first inclined surface 121, thereby initiating the radial expansion action.

[0055] When the movable clamping plate 100b rotates, the first gap between the first inclined surface 121 and the second inclined surface 210 prevents the displacement changes of the drive component 200 inside the movable clamping plate 100b during synchronous rotation from causing interference between the first inclined surface 121 and the second inclined surface 210. Furthermore, in the initial state, there is no contact between the first inclined surface 121 and the second inclined surface 210, which also avoids minor pre-pressure friction caused by manufacturing tolerances or temperature deformation. This is especially beneficial in electric drive mode, reducing motor no-load resistance and extending battery life.

[0056] Please see Figure 3 and Figure 4In the specific operation of this embodiment, when the hair curling plate 120 is held close to the axis of the hair curling tube, the hair curling tube is in a state with a smaller outer diameter. At this time, a first gap is reserved between the first inclined surface 121 of the movable clamping plate 100b and the second inclined surface 210 of the driving member 200. When an opening and closing operation is performed, that is, when the movable clamping plate 100b rotates around the hinge axis to realize the opening or closing of the clamp, the driving member 200 on the movable clamping plate 100b rotates around the end of the transmission link 400 connected to it. During the rotation of the driving member 200 with the movable clamping plate 100b, the driving member 200 will generate a certain displacement in the length direction relative to the movable clamping plate 100b, which is less than the width of the first gap mentioned above.

[0057] Therefore, throughout the entire rotation stroke of the movable clamp 100b, the second inclined surface 210 never contacts the first inclined surface 121, and the two remain separated. This ensures that during the opening and closing action, the drive component 200 will not radially push the curling movable plate 120 open through the inclined surface engagement; that is, the clamping operation of the movable clamp 100b and the outer diameter adjustment function of the curling tube are not coupled. Thus, during normal hair clamping and release, the position of the curling movable plate 120 remains stable and will not unexpectedly move radially due to the opening and closing action of the clamp. This ensures the consistency of the outer diameter of the curling tube before and after clamping, avoids unexpected outer diameter changes interfering with the styling effect, and improves operational reliability and user experience.

[0058] Please see Figure 5 and Figure 6 When the curling plate 120 moves to a position away from the axis of the curling barrel, the outer diameter of the curling barrel increases. In this state, if the movable clamp 100b is opened or closed, the drive member 200 will rotate around the end of the transmission link 400 connected to the push member 300 as a fulcrum, and will generate a corresponding displacement in the length direction of the movable clamp 100b. That is to say, when the curling barrel is in the large outer diameter state, the opening and closing action of the movable clamp 100b only causes the drive member 200 to rotate in conjunction with the movable clamp 100b, and will not produce any pushing effect on the radial position of the curling plate 120.

[0059] Therefore, regardless of whether the curling iron is in a small or large outer diameter state, the rotation caused by the clamping operation of the movable plate 100b will not affect the outer diameter adjustment function of the curling iron. During the normal clamping and releasing of hair, the current outer diameter state of the curling iron will not be accidentally changed, thus ensuring the stability and reliability of the curling operation and avoiding interference with the styling effect caused by unexpected diameter changes due to the opening and closing of the plate.

[0060] In one implementation, please refer to Figures 3 to 7Both the first clamping member and the second clamping member are provided with a driving member 200. The driving member 200 of the first clamping member is connected to the pushing member 300 through a transmission link 400. The driving member 200 of the second clamping member is integrally formed with the pushing member 300.

[0061] When the pusher 300 moves axially under the action of an external force (such as the push force applied by the user through the operation button or the driving force output by the built-in motor through the transmission mechanism), the pusher 300 can simultaneously drive the driving members 200 provided on the first clamping member and the second clamping member, so that the hair curling movable plate 120 installed on the outside of each clamping member can move radially synchronously or in coordination, thereby realizing the dual-sided adjustment of the outer diameter of the hair curling tube.

[0062] The driving component 200 and the pushing component 300 of the second clamping member are integrally molded, meaning they are a single, unified structure. When the pushing component 300 moves axially, this integrated structure directly drives the driving component 200 of the second clamping member to move axially, eliminating the need for intermediate conversion steps. This results in a short transmission path and direct response. The driving component 200 of the first clamping member is connected to the pushing component 300 via a transmission link 400. For details, please refer to [link to relevant documentation]. Figure 7 One end of the transmission link 400 is rotatably connected to the pusher 300, and the other end is rotatably connected to the drive member 200 of the first clamping member. When the pusher 300 moves axially, it pushes the drive member 200 of the first clamping member to move axially via the transmission link 400. Thus, a single axial movement of the pusher 300 can simultaneously drive the drive members 200 on both sides to move, thereby causing their respective corresponding curling movable plates 120 to move radially outward or inward, achieving synchronous increase or decrease in the outer diameter of both sides of the curling tube.

[0063] In one implementation, please refer to Figure 7 , Figure 10 and Figure 12 The fixed clamp 100a includes a clamp body 110, one end of which is provided with a gripping part 160, and a mounting cavity 161 is formed in the gripping part 160. The movable clamp 100b is provided with a pressing part 180 at one end near the gripping part 160, and the pressing part 180 is rotatably connected to the gripping part 160 through a rotating part 170.

[0064] The grip portion 160 serves as the operating part for the user to hold the curling iron, allowing for stable one-handed gripping. An installation cavity 161 is formed inside the grip portion 160. This cavity 161 is a closed or semi-closed hollow space used to accommodate the internal functional components of the curling iron, such as at least a portion of the drive mechanism (including the pusher 300, transmission link 400, power source 500, etc.). Integrating the key components of the drive mechanism within the installation cavity 161 of the grip portion 160 allows for full utilization of the internal space of the curling iron handle.

[0065] The movable clamp 100b has a pressing part 180 at one end near the grip part 160. The pressing part 180 extends to the corresponding position of the grip part 160 for the user to press when holding the curling iron. The pressing part 180 is rotatably connected to the grip part 160 via a rotating part 170. The rotating part 170 can be configured as a pivot, hinge, or pin structure. The rotating part 170 connects both the grip part 160 and the pressing part 180, allowing the movable clamp 100b to rotate relative to the fixed clamp 100a with the rotating part 170 as the fulcrum. When the user presses the pressing part 180, the movable clamp 100b rotates around the rotating part 170, and its clamping end away from the pressing part 180 opens relative to the fixed clamp 100a. At this time, the user can put the hair strand to be styled into the clamping space between the fixed clamp 100a and the movable clamp 100b. After releasing the pressing part 180, the movable clamp 100b rotates and presses towards the fixed clamp 100a under its own elasticity or the action of the return spring, thereby clamping and fixing the hair strand.

[0066] In one implementation, please refer to Figure 1 , Figure 2 , Figure 7 , Figure 10 and Figure 12 The pressing part 180 is provided with a clearance opening 181 for avoiding the pushing member 300 and the transmission connecting rod 400. The pressing part 180 has a third inclined surface 182 on the side facing the gripping part 160, and a clearance space is formed between the third inclined surface 182 and the inner wall surface of the mounting cavity 161. Pressing the pressing part 180 causes the movable clamping plate 100b to rotate around the rotating part 170, so that the movable clamping plate 100b unfolds relative to the fixed clamping plate 100a.

[0067] The pressing part 180 is provided with a clearance opening 181 and a third inclined surface 182. The clearance opening 181 is used to provide a clearance passage for the push member 300 and the transmission linkage 400 installed in the gripping part 160, so as to avoid structural interference during the rotation of the movable clamping plate 100b. The third inclined surface 182 is provided on one side of the pressing part 180, so that a clearance space is formed between the third inclined surface 182 and the corresponding area of ​​the inner wall surface of the mounting cavity 161 under normal conditions, and the pressing part 180 has a larger pressing space to increase the flipping angle of the first clamping plate.

[0068] When the user applies an external force (i.e., inward pressing) toward the axis of the curling barrel to the pressing part 180, the lever structure with the rotating part 170 as the fulcrum converts the pressing action into a rotational torque around the rotating part 170, thereby driving the entire movable clamp 100b to rotate upward or outward, realizing its unfolding relative to the fixed clamp 100a, making it easier to place the hair into the clamping space. The main driving force for the rotation of the movable clamp 100b comes from the lever effect. During this process, the clearance space between the third inclined surface 182 and the inner wall surface of the mounting cavity 161 gradually decreases. This clearance space provides the necessary travel space for the movement of the pressing part 180, thereby enabling the pressing part 180 to press inward smoothly.

[0069] In one implementation, please refer to Figure 7 The clamp body 110 of the fixed clamp 100a and the gripping part 160 are integrally formed.

[0070] The clamp body 110 and the gripping part 160 of the fixing plate 100a are integrally molded, meaning they are made from the same piece of material through processes such as injection molding, die casting, or machining, forming an inseparable single component. This integral molding structure makes the fixing plate 100a a continuous whole from the clamping end to the gripping end, without any splicing gaps or connecting interfaces. This integral molding structure improves the overall rigidity and structural strength of the fixing plate 100a. During use, the clamp body 110 directly bears the radial pressure and bending moment generated by hair entanglement, while the gripping part 160 bears the user's gripping force and operating pressure. After the two are integrally molded, stress can be continuously transferred within the whole component, avoiding the risk of breakage or deformation caused by stress concentration at the connection points in a separate structure, thus improving the load-bearing capacity and service life of the curling iron.

[0071] In one implementation, please refer to Figure 3 and Figure 7 The drive mechanism also includes a power source 500 installed on the curling cylinder. The power source 500 is located on the side of the push member 300 away from the transmission link 400 and is connected to the drive push member 300 so as to drive the drive member 200 to move axially along the curling cylinder through the transmission link 400.

[0072] The drive mechanism also includes a power source 500 installed on the curling barrel. The power source 500 is located on the side of the push member 300 away from the transmission link 400, that is, the push member 300 is disposed between the power source 500 and the transmission link 400, and the power source 500 is arranged at the rear end of the push member 300. The power source 500 is drivenly connected to the push member 300, and its output driving force acts directly on the push member 300, pushing the push member 300 to move axially along the curling barrel. In turn, the drive member 200 is driven to move axially along the curling barrel through the transmission link 400, and finally the radial displacement of the curling movable plate 120 is realized, thus completing the adjustment of the outer diameter of the curling barrel.

[0073] The power source 500 can take various forms, such as a micro DC motor with a lead screw and nut transmission mechanism, an electromagnet, or a shape memory alloy actuator. For example, the rotational motion of the motor is converted into the linear reciprocating motion of the pusher 300 through the lead screw and nut, resulting in high transmission efficiency and good control precision. The start and stop of the power source 500 can be controlled by a control button or toggle switch located on the curling iron grip 160. The user can easily adjust the outer diameter of the curling iron by simply touching the button. By positioning the power source 500 on the side of the pusher 300 away from the transmission link 400, the power source 500, the pusher 300, and the transmission link 400 are arranged sequentially along the axial direction of the curling iron. The axial thrust output by the power source 500 is transmitted to the pusher 300 via the shortest path, reducing intermediate transmission links and avoiding multiple changes in the direction of motion, thereby reducing transmission energy loss and improving transmission efficiency. In addition, this layout makes full use of the internal mounting cavity 161 space of the curling iron grip 160. The main body of the power source 500 can be accommodated in the mounting cavity 161 of the grip 160 without increasing the external outline size of the curling iron, thus maintaining the compact shape and lightweight feel of the curling iron.

[0074] Please see Figure 5 In one embodiment, the power source 500 may include a drive motor 510 and a screw 520. The drive mechanism also includes a drive base 700. The drive base 700 is provided with a threaded connection 710 that is threadedly engaged with the screw 520, and the pusher 300 is fixedly connected to the drive base 700. When the drive motor 510 drives the screw 520 to rotate, the drive base 700 drives the pusher 300 to move along the axial direction of the hair curling cylinder.

[0075] The output shaft of the drive motor 510 extends axially along the curling cylinder, and the screw 520 is fixed to the output shaft and coaxially arranged with it. The threaded portion 710 of the drive seat 700 is sleeved on the screw 520, and the inner wall of the threaded portion 710 has an internal thread that matches the external thread of the screw 520. The pusher 300 is fixedly connected to the drive seat 700. The two can be an integrally formed structure, or they can be fixedly connected by screws, clips, or welding.

[0076] When the drive motor 510 drives the screw 520 to rotate, the rotational motion of the screw 520 is converted into the axial motion of the drive seat 700 through the threaded engagement. Since the drive seat 700 is fixedly connected to the push member 300, and the push member 300 is restricted to axial movement within the mounting cavity 161, the drive seat 700 and the push member 300 move together along the axial direction of the curling cylinder without circumferential rotation.

[0077] In one embodiment, the first clamping member and / or the second clamping member further includes a fixed mounting bracket 130, the pushing member 300 is provided with a mounting groove 310 on the side facing the driving member 200, the hair curler further includes a fan 600 installed in the mounting groove 310, the pushing member 300 is provided with an air inlet 320 communicating with the mounting groove 310 and the external space, and the hair curling movable plate 120 and / or the fixed mounting bracket 130 is provided with an air outlet.

[0078] The pusher 300 has a mounting groove 310 on the side facing the drive member 200, which is directly connected to the mounting cavity 161 in the grip 160. A fan 600 (such as a miniature axial fan or centrifugal fan) is mounted in the mounting groove 310, and its power source can be a built-in battery or an external power supply interface. The pusher 300 has an air inlet 320 to allow the fan 600 to introduce airflow. The curling plate 120 and / or the fixed mounting bracket 130 have an air outlet, which is connected to the mounting groove 310, allowing airflow to be finally discharged from the mounting groove 310 through the air outlet.

[0079] When the user activates the curling iron's heating function, the fan 600 runs simultaneously. External air enters the mounting slot 310 through the air inlet 320 on the pusher 300. After being pressurized by the fan 600, the airflow is blown onto the hair on the surface of the curling iron through the air outlet on the fixed mounting bracket 130 and / or the curling movable plate 120, helping the keratin to set quickly.

[0080] In one implementation, please refer to Figures 3 to 7 The first clamping member includes a clamping plate body 110, a fixed mounting bracket 130, and a resetting member 140. The fixed mounting bracket 130 and the corresponding clamping plate body 110 together define a receiving cavity 150. The resetting member 140 is disposed in the receiving cavity 150 and is connected to the fixed mounting bracket 130 and the hair curling movable plate 120, and is used to apply a driving force to the hair curling movable plate 120 to move in the direction of the hair curling cylinder axis.

[0081] The fixed mounting bracket 130 is a rigid support structure, which can be made of heat-resistant engineering plastic or metal. It is fixedly connected to the clamp body 110 and is used to support the guiding movement of the curling movable plate 120 and carry the reset member 140. The reset member 140 is disposed inside the receiving cavity 150, with one end connected to the fixed mounting bracket 130 and the other end connected to the curling movable plate 120. Its function is to actively apply a restoring force in the direction of the curling cylinder axis after the driving mechanism removes the thrust, causing the curling movable plate 120 to automatically retract to its initial position (such as from rising to falling). The reset member 140 can be a helical compression spring, a sheet spring, a rubber elastomer, or a magnetic reset device.

[0082] When the curling iron is in its initial state, the curling plate 120 is housed within the receiving groove and the opening is sealed. When the user operates the drive mechanism to advance the drive member 200 axially, the curling plate 120 overcomes the elastic force of the reset member 140 and moves radially outward. The curling plate 120 expands radially outward to open the receiving groove 131 and is located outside the receiving groove 131, increasing the outer diameter of the curling tube. When the drive member 200 retracts, the reset member 140 releases its stored elastic potential energy, pulling the curling plate 120 back to its initial state, achieving automatic reset, and the curling plate 120 returns to the receiving groove 131.

[0083] In one implementation, please refer to Figures 4 to 8 The curling plate 120 has a connecting post 123 on the side facing the clamp body 110. The fixed mounting bracket 130 has a connecting hole 132 for the connecting post 123 to pass through. The reset member 140 is configured as an elastic member, which is sleeved on the outer periphery of the connecting post 123, with one end connected to the connecting post 123 and the other end abutting against the outer edge of the connecting hole 132.

[0084] The connecting post 123 is integrally formed or fixedly disposed on the inner side of the curling movable plate 120 (i.e., the side facing the clamp body 110), and can serve as the inner connection point of the elastic element and the motion guide shaft. The fixed mounting bracket 130 is provided with a corresponding connecting through hole 132, the diameter of which is slightly larger than the outer diameter of the connecting post 123, allowing the connecting post 123 to slide freely in the axial direction (i.e., the radial direction of the curling tube), while restricting its lateral displacement. The elastic element (such as a compression spring or a coil spring) is sleeved on the outer periphery of the connecting post 123. One end of the elastic element can be connected to the limiting step, slot or end face on the connecting post 123, or abut against the limiting protrusion at the end of the connecting post 123, and the other end abuts against the annular edge (i.e., the "outer edge") of the connecting through hole 132 near the receiving cavity 150, so that it is compressed and stored when the curling movable plate 120 moves outward, and the energy is released after the driving force is removed to push the curling movable plate 120 back to its original position.

[0085] The connecting post 123 and the connecting through hole 132 form a precision guide pair, which effectively constrains the curling motion plate 120 to move only in a radial straight line, preventing it from tilting, shaking or rubbing abnormally during movement. Secondly, the elastic element is coaxially sleeved on the connecting post 123, which is easy to install and accurately positioned, without the need for additional brackets or fixing structures, saving internal space and contributing to the miniaturization and weight reduction of the whole machine. Thirdly, the two ends of the elastic element act on the connecting post 123 and the fixed mounting bracket 130 respectively, forming a closed force circuit, ensuring stable output of restoring force, and significantly improving the reliability and consistency of the reset action.

[0086] When the user operates the drive mechanism to push the drive component 200 axially, the curling plate 120 moves radially outward under the action of the inclined plane thrust, causing the connecting post 123 to simultaneously pass through the connecting hole 132 and extend outward. At this time, the elastic element sleeved on the outer periphery of the connecting post 123 is compressed, with one end moving with the connecting post 123 and the other end continuously pressing against the outer edge of the connecting hole 132, storing elastic potential energy. When the user stops applying force or reverses the operation of the drive mechanism, the driving thrust disappears, the elastic element releases energy, and pushes the connecting post 123 and the curling plate 120 fixed to it to retract smoothly along the original path.

[0087] In one implementation, please refer to Figures 4 to 6 , Figure 11 The drive component 200 is provided with a clearance hole 230 for the connecting post 123 to pass through, and the clearance hole 230 extends along the axis of the hair curler.

[0088] The connecting post 123 extends radially from the inside of the curling active plate 120 and needs to pass through the connecting through hole 132 of the fixed mounting bracket 130 to achieve the reset function. The driving member 200 is located in the receiving cavity 150 between the clamp body 110 and the curling active plate 120 and needs to move along the axis of the curling cylinder to push the curling active plate 120 to expand radially. There is a potential possibility of overlap between the two in the assembly space.

[0089] Therefore, by providing a clearance hole 230 on the drive member 200, the connecting post 123 is allowed to pass freely through the drive member 200 without collision or obstruction during the radial movement of the curling plate 120. Moreover, the clearance hole 230 extends along the axis of the curling tube, that is, its length direction is parallel to the movement direction of the drive member 200, and its extension length should not be less than the maximum axial stroke of the drive member 200. This ensures that sufficient passage space is always provided for the connecting post 123 throughout the entire axial stroke range of the drive member 200, preventing the edge of the clearance hole 230 from scraping or getting stuck with the connecting post 123 due to displacement of the drive member 200.

[0090] In this way, the axial sliding of the drive component 200 and the radial extension and retraction of the curling plate 120 can be ensured to not interfere with each other, thereby improving the coordination and reliability of the overall mechanism; it can also maintain the compactness of the structure, and achieve the coexistence of multiple degrees of freedom of motion without increasing the volume of the receiving cavity 150 or changing the arrangement of components, which is conducive to product miniaturization and weight reduction.

[0091] It is worth mentioning that the air outlet can be located on the fixed mounting bracket 130. The air outlet can be a strip-shaped hole, and there can be multiple air outlets, which can be spaced apart along the length of the hair curling tube. The location of the air outlet can take various forms. In one embodiment, the air outlet is located on the fixed mounting bracket 130 and is adjacent to or spaced apart from the hair curling plate 120. It is understood that the hair curling plate 120 can also be equipped with air outlets to increase the airflow and facilitate hair cooling and styling.

[0092] In one implementation, please refer to Figures 7 to 9 The fixed mounting bracket 130 is provided with multiple receiving slots 131 for accommodating the hair curling active plate, and multiple hair curling active plates 120 are provided, which are distributed at intervals along the circumference of the hair curling tube.

[0093] The fixed mounting bracket 130 is provided with multiple receiving slots 131, which are arranged at equal or non-equal intervals around the circumference of the hair curling tube. Correspondingly, multiple hair curling movable plates 120 are provided, each hair curling movable plate 120 being movably mounted on the fixed mounting bracket 130 through a receiving slot 131, and forming an independent but synchronous radial telescopic unit. Each hair curling movable plate 120 has a connecting post 123, a first inclined surface 121 and a reset member 140 on its inner side, and they share the same driving member 200 or are controlled by a linkage driving mechanism, so that when the driving member 200 moves axially, all hair curling movable plates 120 synchronously expand outward or retract inward radially, so that the outer contour of the entire hair curling tube maintains an approximately cylindrical shape.

[0094] By using multiple curling plates 120 to expand collaboratively, a curling surface closer to a cylinder can be formed. This reduces the problem of traditional single-plate movement in one direction, which results in an elliptical curling tube after expansion, making it impossible to achieve the desired round curling effect. It also enhances structural rigidity and load-bearing capacity. The segmented layout disperses thermal stress and mechanical loads, reducing the risk of deformation of a single plate, which is especially suitable for large outer diameters. Furthermore, it allows for differentiated control of plates at different circumferential positions (such as partial expansion or partial fixation), enabling asymmetrical shapes such as elliptical curls and wavy curls, further enriching product functionality.

[0095] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
