Description

Technical Field

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

[0002] Most existing hair curlers include a handle and a curling section connected to the handle. The curling section is equipped with a heat-conducting component to heat the hair and achieve a curling effect for styling. However, since the heat-conducting component is fixed in this type of curling section, it can only provide one curl size, resulting in limited styling options. When other styling needs are required, it may be necessary to purchase a different model of hair curler, increasing the cost of use.

[0003] Therefore, how to increase the styling capabilities of curling irons is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide a curling section for a hair curler that can increase the styling ability of the hair curler.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A curling section for a hair curler includes a heat-conducting assembly, a fixing section, and a rotating section. The heat-conducting assembly includes at least two heat-conducting elements arranged sequentially around a preset center line to form a cylindrical structure. One end of each heat-conducting element is radially movable and connected to the fixing section, and the other end is radially movable or rotatably connected to the fixing section. The rotating section is rotatably connected to the fixing section. The heat-conducting element is slidably connected to the rotating section, and during the rotation of the rotating section, at at least one angle, the two ends of the exposed side of the heat-conducting element are spaced the same from the preset center line so that the exposed side of the heat-conducting assembly is cylindrical. Furthermore, during the rotation of the rotating section, the two ends of the heat-conducting element have different motion trajectories relative to the rotating section, allowing the exposed side of the heat-conducting assembly to switch between a cylindrical surface and a conical surface.

[0007] Preferably, the two ends of the heat-conducting component are respectively radially movable and connected to the fixed part, and the two ends of the heat-conducting component are respectively slidably connected to the guide structure of the rotating part, so as to constrain the two ends of the heat-conducting component to move along different motion trajectories on the rotating part during the rotation of the rotating part.

[0008] Preferably, within the first angular range of rotation of the rotating part, the two ends of the heat-conducting element have the same motion trajectory on the rotating part.

[0009] Preferably, within the first angular range of rotation of the rotating part, the exposed side of the heat-conducting component remains cylindrical.

[0010] Preferably, within the second angle range of the rotation of the rotating part, in the motion trajectories of the two ends of the heat-conducting component on the rotating part, the distance between one motion trajectory and the preset center line in the circumferential direction gradually decreases, while the distance between the other motion trajectory and the preset center line in the circumferential direction gradually increases or first gradually increases and then gradually decreases.

[0011] Preferably, the rotating part includes a rotating rod rotatably connected to the fixed part and two rotating plates fixed to the rotating rod. The two ends of the heat-conducting element are respectively slidably connected to the trajectory grooves on the two rotating plates. During the rotation of the rotating part, the motion trajectory of the two ends of the heat-conducting element on the rotating part is respectively constrained by the two trajectory grooves.

[0012] Preferably, the heat-conducting component has two first connecting posts that slide to connect the two track grooves at both ends, and the two first connecting posts are collinear. The exposed side of the heat-conducting component is the same radial distance from the two first connecting posts.

[0013] Preferably, the heat-conducting component has two second connecting posts that are slidably connected to the two track grooves at both ends, and the two second connecting posts are arranged in parallel. The radial distance between the exposed side of the heat-conducting component and the two second connecting posts is different.

[0014] Preferably, in the two rotating plates, the axial projection of the outer peripheral surface of one rotating plate is located inside the outer peripheral surface of the other rotating plate.

[0015] Preferably, the first end of the heat-conducting component is rotatably connected to the fixed part, and the second end is radially movable and slidably connected to the fixed part and the rotating part. During the rotation of the rotating part, the distance between the second end of the heat-conducting component and the preset center line at each position of the circumferential trajectory on the rotating part gradually decreases.

[0016] The present invention provides a curling section for a hair curler, comprising a heat-conducting component, a fixing component, and a rotating component. The heat-conducting component includes at least two heat-conducting elements arranged sequentially around a preset center line to form a cylindrical structure. One end of each heat-conducting element is radially movable and connected to the fixing component, and the other end is radially movable or rotatably connected to the fixing component. The rotating component is rotatably connected to the fixing component. During the rotation of the rotating component, at at least one angle, the two ends of the exposed side of the heat-conducting element are spaced at the same distance from the preset center line so that the exposed side of the heat-conducting component is cylindrical. During the rotation of the rotating component, the two ends of the heat-conducting element move along different trajectories relative to the rotating component, allowing the exposed side of the heat-conducting component to switch between a cylindrical surface and a conical surface.

[0017] At at least one angle, the distance between the two ends of the exposed side of the heat-conducting component and the preset center line is the same, which can ensure that the exposed side of the heat-conducting component has a cylindrical state. When the rotating part rotates, the fixed part constrains the heat-conducting component to move radially but not circumferentially. Since the two ends of the heat-conducting component have different motion trajectories relative to the rotating part, the radial movement distance of the two ends of the heat-conducting component is not always the same when the rotating part rotates from the angle corresponding to the cylindrical surface to other angles on the exposed side of the heat-conducting component. The cylindrical surface can be switched to a conical surface, so that the shape of the cylindrical structure can be switched between a cylindrical structure and a conical structure, which can increase the styling ability of the curling iron.

[0043] 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.

[0044] The core of this invention is to provide a curling section for a hair curler, which can increase the styling ability of the hair curler.

[0045] The core of this invention is to provide a curling section for a hair curler, which can increase the styling ability of the hair curler.

[0046] The curling section of the present invention for a hair curler is applied to a hair curler. For example... Figure 1 As shown, the hair curler includes a handle 5 and a curling part connected to the handle 5. The curling part heats the hair to curl it, thereby achieving hair styling and shaping.

[0047] In specific embodiment one, refer to Figures 2 to 11 The curling section includes a heat-conducting component 1, a fixing part 2, and a rotating part 3.

[0048] like Figures 2 to 4 As shown, the heat-conducting component 1 includes at least two heat-conducting elements 11 arranged sequentially around a preset center line. Specifically, three are provided. In other embodiments, two, four or other quantities of heat-conducting elements 11 may also be provided so that the heat-conducting component 1 forms a cylindrical structure.

[0049] In this invention, unless otherwise specified, the axial, circumferential, and radial directions are based on a preset center line, which extends in the axial direction. Typically, the preset center line is collinear with the center line of the curling section.

[0050] One end of the heat-conducting element 11 is radially movable and connected to the fixed part 2, and the other end is radially movable and connected to the fixed part 2. The rotating part 3 is rotatably connected to the fixed part 2, and the heat-conducting element 11 is slidably connected to the rotating part 3. The heat-conducting element 11 generally extends along the axial direction, and unless otherwise specified, the two ends of the heat-conducting element 11 are its two ends along the axial direction.

[0051] In use, the fixed part 2 remains stationary, while the rotating part 3 rotates relative to the fixed part 2. The fixed part 2 constrains the movement direction of the heat-conducting component 11, so that each point on the heat-conducting component 11 that moves moves radially. The rotating part 3 adjusts the radial movement distance of the heat-conducting component 11. By rotating, the radial movement distance of different positions on the heat-conducting component 11 is adjusted accordingly.

[0052] During the rotation of the rotating part 3, at at least one angle, the two ends of the exposed side of the heat-conducting component 11 are equidistant from a preset centerline, so that the heat-conducting assembly 1 is a cylinder. Furthermore, during the rotation of the rotating part 3, the two ends of the heat-conducting component 11 move along different trajectories relative to the rotating part 3, allowing the exposed side of the heat-conducting assembly 1 to switch between a cylindrical surface and a conical surface. When the exposed side of the heat-conducting component 1 is a cylindrical surface, the shape of the cylindrical structure is considered a cylinder; when the exposed side of the heat-conducting component 1 is a conical surface, the shape of the cylindrical structure is considered a cone.

[0053] It should be noted that the exposed side of the heat-conducting component 11 refers to the surface that is exposed and can directly contact the hair after it is assembled with the curling iron. Figure 2 In region D, where 1, the two ends of the exposed side of the heat-conducting element 11 are the two ends d1 and d2 in the axial direction. Similarly, the entire surface enclosed by the exposed sides of all the heat-conducting elements 11 is the exposed side of the heat-conducting assembly 1, as shown in the reference. Figure 1 The E region is located in the axial direction.

[0054] In this embodiment, at at least one angle, the two ends of the exposed side of the heat-conducting component 11 are spaced at the same distance from the preset center line, which can ensure that the exposed side of the heat-conducting component 1 has a cylindrical state. When the rotating part 3 rotates, the fixing part 2 constrains the heat-conducting component 11 to move radially but not circumferentially. Since the two ends of the heat-conducting component 11 have different motion trajectories relative to the rotating part 3, the radial movement distance of the two ends of the heat-conducting component 11 is not always the same when the rotating part 3 rotates from the angle corresponding to the cylindrical surface to other angles on the exposed side of the heat-conducting component 1. The cylindrical surface can be switched to a conical surface, so that the shape of the cylindrical structure can be switched between a cylindrical structure and a conical structure, which can increase the styling ability of the curling iron.

[0055] Further, please refer to Figures 5 to 11 Both ends of the heat-conducting component 11 are radially movable and connected to the fixed part 2, while both ends of the heat-conducting component 11 are slidably connected to the rotating part 3. With the fixed part 2 as a stationary reference frame, when the rotating part 3 rotates, the heat-conducting component 11 moves radially while remaining stationary circumferentially. This requires that the connection point between the rotating part 3 and the heat-conducting component 11 has a guide structure extending obliquely in the circumferential direction. The heat-conducting component 11 is slidably connected to the guide structure to constrain both ends of the heat-conducting component 11 to move along different trajectories on the rotating part 3 during rotation. The circumferential oblique extension of the guide structure means that the guide structure is not perfectly equidistant from the preset center line at various positions in the circumferential direction.

[0056] Preferably, in this embodiment, the reference Figure 2 The rotating part 3 includes a rotating rod 31 rotatably connected to the fixed part 2 and two rotating plates 32 fixed to the rotating rod 31. The two ends of the heat-conducting element 11 are slidably connected to the track grooves 321 on the two rotating plates 32, as shown below. Figure 9As shown, the trajectory grooves 321 connected to both ends of the same heat-conducting component 11 are A and B, respectively. During the rotation of the rotating part 3, the movement trajectories of both ends of the heat-conducting component 11 in the rotating part 3 are respectively constrained by the two trajectory grooves 321. At this time, the trajectory grooves 321 serve as guiding structures, which are easy to process. Correspondingly, the trajectory grooves 321 provided on the rotating plate 32 extend obliquely relative to the circumference, so that the distances of various points on the trajectory grooves 321 relative to the preset center line are not completely the same, including cases where they are completely different or partially different. The preset center line is also the rotation center line of the rotating plate 32. Specifically, the trajectory grooves 321 are axial through grooves.

[0057] In addition, such as Figure 2 As shown, the fixing part 2 includes a mounting base 21, and the rotating part 3 is rotatably connected to the mounting base 21. The mounting base 21 is provided with a radially extending radial groove 211, which can provide at least two limiting points. At this time, both ends of the heat-conducting element 11 are slidably connected to the radial groove 211 and the trajectory groove 321, respectively, so that the rotation of the rotating part 3 can drive the heat-conducting element 11 to move radially along the radial groove 211, and can position the heat-conducting element 11 in the radial direction, so as to switch the limiting points where the heat-conducting element 11 stops on the radial groove 211, thereby adjusting the distance and included angle between the rotation center lines of the heat-conducting element 11 and the rotating plate 32, and allowing the shape of the cylindrical structure to switch between a cylindrical structure and a conical structure.

[0058] Of course, in other embodiments, the track groove 321 in this embodiment can be replaced with a groove that does not penetrate axially; or it can be replaced with a protruding structure. In this case, the heat-conducting component 11 is provided with a sliding groove to slide and engage with the protruding structure.

[0059] Further, refer to Figure 8 , Figure 9 and Figure 11 Within the first angular range of rotation of the rotating part 3, the two ends of the heat-conducting element 11 move along the same trajectory on the rotating part 3. Correspondingly, as... Figure 8 and Figure 9 As shown, when the rotating part 3 moves within this angular range, the connection point of one end of the heat-conducting component 11 on the track groove A is located between points a0 and a1, and the connection point of the other end of the heat-conducting component 11 on the track groove B is located between points b0 and b1. The guide trajectories between points a0 and a1 and between points b0 and b1 can overlap after translation in space. Therefore, the two ends of the heat-conducting component 11 constrained by both have the same motion trajectory relative to the rotating part 3. Within this angular range, when the rotating part 3 moves from one angle to another, the radial distances of the two ends of the heat-conducting component 11 are the same, and the heat-conducting component 11 as a whole translates radially, so that the shape of the cylinder structure does not change even if its thickness is changed.

[0060] Specifically, in this embodiment, within the first angle range, the exposed side of the heat-conducting component 1 remains cylindrical, meaning its diameter changes, and the axial cross-section of the cylindrical structure can be as follows: Figure 11 The change from S1 to S2 also improves the applicability of the curling section. Of course, in other embodiments, the exposed side of the heat-conducting component 1 can also remain a conical surface within this angle range.

[0061] Furthermore, such as Figures 9 to 11 As shown, within the second angular range of rotation of the rotating part 3, in the motion trajectories of the two ends of the heat-conducting member 11 on the rotating part 3, the distance between one motion trajectory and the preset center line in the circumferential direction gradually decreases, while the distance between the other motion trajectory and the preset center line in the circumferential direction gradually increases. Correspondingly, as... Figure 9 and Figure 10 As shown, when the rotating part 3 moves within this angular range, the connection point of one end of the heat-conducting component 11 on the track groove A is located between points a1 and a2, and the connection point of the other end of the heat-conducting component 11 on the track groove B is located between points b1 and b2. The guide trajectories between points a1 and a2 and between points b1 and b2 can be translated in space without overlapping. Therefore, the two ends of the heat-conducting component 11 constrained by the two will have different motion trajectories relative to the rotating part 3. Within this angular range, when the rotating part 3 moves from one angle to another, the radial distances of the two ends of the heat-conducting component 11 may be different. For example, the distance of movement at one end may decrease, while the distance of movement at the other end may increase. The heat-conducting component 11 as a whole will swing relative to the preset centerline. The cylindrical structure can change from a column to a cone after the rotating part 3 moves from the first angular range to the second angular range. The axial cross section of the cylindrical structure is approximately composed of... Figure 11 S2 in the equation becomes S3, and the taper can be changed.

[0062] Of course, in other embodiments, a section with the same structure as between points a0 and a1 can be added on the side of point a2 away from point a1 on track groove A, and a section with the same structure as between points b0 and b1 can be added on the side of point b2 away from point b1 on track groove B, so that the cylindrical structure can be changed from a cone to a column again.

[0063] Furthermore, such as Figure 2 and Figure 3As shown, the heat-conducting component 11 has two first connecting posts 6 that are slidably connected to two trajectory grooves 321 at both ends, and the two first connecting posts 6 are collinearly arranged. The exposed side of the heat-conducting component 11 is equidistant from the radial distance of the two first connecting posts 6. That is, in this case, the heat-conducting component 11 can have a relatively regular structure. When the distance between the two trajectory grooves 321 and the preset center line is the same, the distance between the exposed side of the heat-conducting component 11 and the preset center line is also the same, which facilitates processing and the setting of the extension direction of the trajectory grooves 321. Alternatively, in this embodiment, the radial distance between the exposed side of the heat-conducting component 11 and the two first connecting posts 6 may not be the same. Or, in other embodiments, such as... Figure 16 As shown, the heat-conducting component 11 has two second connecting posts 7 that are slidably connected to two track grooves 321 at both ends, and the two second connecting posts 7 are arranged in parallel. The radial distance between the exposed side of the heat-conducting component 11 and the two second connecting posts 7 is different. At this time, it is necessary to combine the distance between the rotating grooves at both ends of the heat-conducting component 11 and the preset center line, as well as the distance between the exposed side of the heat-conducting component 11 and the second connecting posts 7, in order to achieve the formation of the column.

[0064] Furthermore, such as Figure 10 As shown, in the two rotating plates 32, the axial projection of the outer peripheral surface of one rotating plate 32 is located inside the outer peripheral surface of the other rotating plate 32. Since the distance between each point on the two track grooves A and B and the preset center line varies, the maximum value of the distance from the preset center line may also be different. Adaptively setting the size of the two rotating plates 32 according to this maximum value helps to save materials and costs. Of course, in other embodiments, the axial projection of the outer peripheral surface of one rotating plate 32 may also coincide with the outer peripheral surface of the other rotating plate 32.

[0065] Furthermore, such as Figure 2 As shown, the track groove 321 has an arc-shaped structure, which allows the heat-conducting component 11 to move smoothly. In other embodiments, the track groove 321 may also be a straight structure or a V-shaped structure with sharp turns.

[0066] Further, refer to Figure 5 and Figure 6 On the same rotating plate 32, the trajectory grooves 321 are evenly arranged circumferentially and have the same structure. Here, the same structure means that the trajectory grooves 321 rotate around the rotation center line of the rotating plate 32 and can coincide in the same virtual set area. Based on this setting, the radial movement distance of each heat conduction component 11 is consistent under the drive of the rotating plate 32, and the shape of the cylinder structure is relatively regular.

[0067] More specifically, such as Figure 4 As shown, the rotating plate 32 is fixedly connected to the rotating cap 4, which is sleeved on the outside of the mounting base 21. Rotating the rotating cap 4 drives the rotating plate 32 and the rotating rod 31 to rotate.

[0068] Furthermore, the exposed sides of each heat-conducting element 11 are arc-shaped surfaces. Correspondingly, if a cylindrical structure is formed, it is a cylindrical tube; if a conical structure is formed, it is a frustum or a cone. In other embodiments, the heat-conducting element 11 may also be generally straight, and the conical structure formed by the heat-conducting assembly 1 may also be a square pyramidal structure. In addition, for the conical structure, the end connected to the handle portion 5 may be a large-diameter end or a small-diameter end. Furthermore, there may be gaps between adjacent heat-conducting elements 11, or a closed structure may be maintained by adjusting the overlapping area.

[0069] In this embodiment, the radial groove 211 of the curling section constrains the heat-conducting component 11 to move radially but not circumferentially. Since the trajectory groove 321 on the rotating plate 32 extends obliquely relative to the circumferential direction, the distance between the various points on the trajectory groove 321 and the rotation center line of the rotating plate 32 is not exactly the same. This allows the trajectory groove 321 to move circumferentially relative to the heat-conducting component 11 while simultaneously pushing the heat-conducting component 11 radially during the rotation of the rotating plate 32. This allows adjustment of the distance or angle between the heat-conducting component 11 and the rotation center line of the rotating plate 32, thereby adjusting the shape or size of the cylindrical structure. Furthermore, it allows the shape of the cylindrical structure to switch between a cylindrical structure and a conical structure, increasing the styling capability of the curling iron.

[0070] In the second specific embodiment, the movement trajectories of the two ends of the heat-conducting component 11 relative to the rotating part 3 can be configured in other ways, as shown in the reference. Figure 12 and Figure 13 In this embodiment, one of the rotating plates 32, 32A, remains the same as in Embodiment 1, while the other rotating plate 32 is replaced with another type of rotating plate 32: the distance between the track groove 321 of this rotating plate 32 and the preset center line decreases continuously clockwise or counterclockwise along one direction in the circumferential direction. In this embodiment, the cylindrical structure may be a cylindrical structure only at one rotation angle of the rotating plate 32, while it remains a conical structure at other rotation angles, and the taper can continuously change during the rotation of the rotating plate 32.

[0071] In a specific embodiment three, the heat-conducting component 11 can be connected to the rotating part 3 and the fixing part 2 in another way. For example... Figure 14 and Figure 15 As shown, the first end of the heat-conducting component 11 is rotatably connected to the fixing part 2, specifically connected to the fixing seat 22 of the fixing part 2. The second end is radially movable and connected to the fixing part 2 and slidably connected to the rotating part 3. During the rotation of the rotating part 3, the distance between the second end of the heat-conducting component 11 and the preset center line at different positions in the circumferential direction is not exactly the same, and gradually decreases. At this time, when the rotating part 3 rotates, the heat-conducting component 11 swings relative to its first end and the preset center line to adjust the angle between the heat-conducting component 11 and the preset center line. At this time, the cylindrical structure can be a cylindrical structure only at one rotation angle of the rotating part 3, while it is always a conical structure at other rotation angles.

[0072] The curling part provided by the present invention has a fixing part 2 with at least two radial limiting points. During the rotation of the rotating part 3, the heat-conducting part 11 can be pushed to move at different limiting points, which can realize the size change and / or shape change of the cylindrical structure. It can provide the cylindrical structure to switch between multiple combinations of cylinders and cones, or even cross combinations, to achieve a rich variety of styles.
