Description

Technical Field

[0001] This utility model relates to the field of curling iron technology, and in particular to a heat-resistant, wrap-around automatic curling iron structure that facilitates the replacement of curling heads. Background Technology

[0002] With the continuous development and progress of society and the continuous improvement of people's quality of life, hair styling is receiving more and more attention. There are many types of hair styling devices used, and curly and straight hair styling are frequently used styling options.

[0003] When creating curls, users typically use a series of curling tools such as curling irons, curling pliers, and curling balls to achieve the desired curl effect. Users can use various curling irons with different diameters of curling heads to curl straight hair into various curls and shapes, such as large waves, small spirals, natural drooping curls, and wheat ear curls. However, the curling heads of existing heat-resistant automatic curling irons are fixed in size and cannot be disassembled or replaced. They can only curl hair with a single degree of curvature and cannot be used to curl hair with different curvatures. Users often need to select or use a variety of curling irons with different diameters of curling heads when curling their hair. The curling heads of heat-resistant automatic curling irons are mostly fixed and cannot be disassembled or replaced, which is very inconvenient to use and cannot meet the needs of users. Utility Model Content

[0004] The purpose of this invention is to provide a heat-resistant, wrap-around automatic curling iron structure that facilitates the replacement of the curling head, aiming to solve the technical problem that the curling head of the heat-resistant, wrap-around automatic curling iron in the prior art cannot be disassembled and replaced.

[0005] To achieve the above objectives, the present invention provides a heat-resistant, wrap-around automatic curling iron structure that facilitates the replacement of the curling head, comprising:

[0006] A handle assembly, wherein the handle assembly is hollow and one end of the handle assembly has a first opening, and a drive assembly and a heating rod are disposed in the handle assembly;

[0007] The mounting collar is rotatably mounted in the handle assembly, and is drivenly connected to the drive assembly. The mounting collar is provided with a first magnetic positioning structure.

[0008] A hair curling head, comprising a shell and a curling shell, one end of the shell having a second opening for fitting the shell onto the heating rod through the second opening, the curling shell being rotatably mounted on the shell, and the curling shell being provided with a second magnetic positioning structure, so that the driving component can drive the curling shell to rotate by magnetically connecting the second magnetic positioning structure and the first magnetic positioning structure to each other;

[0009] In this configuration, one of the first magnetic positioning structure and the second magnetic positioning structure is a magnetic column structure, and the other of the first magnetic positioning structure and the second magnetic positioning structure is a magnetic hole structure. The magnetic column structure and the magnetic hole structure are arranged correspondingly so that by inserting the magnetic column structure into the magnetic hole structure, the second magnetic positioning structure and the first magnetic positioning structure are magnetically connected to each other, thereby causing the driving component to drive the curling shell to rotate.

[0010] Furthermore, the magnetic column structure includes a hollow column and a first ferromagnetic component. The hollow column is installed on the side of the curling shell facing the mounting collar. The first ferromagnetic component is embedded in the hollow column. The magnetic hole structure is opened on the side of the mounting collar facing the curling shell. A second ferromagnetic component is provided in the magnetic hole structure.

[0011] Furthermore, the housing includes a body, a movable groove, and an extension rod. The body is fitted onto the heating rod, the movable groove is fitted and fixed to one end of the body, and one end of the extension rod is screwed to the other end of the body.

[0012] Furthermore, it also includes a mounting shaft, which is installed in the handle assembly and is coaxially arranged with the handle assembly. The mounting collar is rotatably sleeved on the mounting shaft, and one end of the heating rod is connected to the mounting shaft.

[0013] Furthermore, the other end of the extension rod extends through the first opening into the handle assembly.

[0014] Furthermore, the movable slot is provided with a first micro-fixing structure, and the curling shell is provided with a second micro-fixing structure corresponding to the first micro-fixing structure, so that when the curling head is disassembled and replaced, the curling shell can be rotated to a position where the first micro-fixing structure and the second micro-fixing structure are attracted to each other.

[0015] Furthermore, the other end of the extension rod extends 4-12cm through the first opening.

[0016] Furthermore, the first micro-fixed structure includes a rolling groove and a magnetic ball. The rolling groove is formed in the lower groove wall of the movable groove, and the magnetic ball can roll in the rolling groove. The second micro-fixed structure includes an embedding groove and a third ferromagnetic component. The embedding groove is formed circumferentially on the inner circumferential surface of the curling shell, and the third ferromagnetic component is embedded in the embedding groove. By rotating the curling shell, the third ferromagnetic component can be attracted to the magnetic ball.

[0017] Furthermore, the outer peripheral surface of the heating rod is provided with a first limiting structure, and the inner peripheral surface of the shell is provided with a second limiting structure. The shell is slidably fitted onto the heating rod, and the first limiting structure and the second limiting structure can engage with each other so that the shell and the heating rod cannot rotate relative to each other.

[0018] As can be seen from the above technical solution, the heat-resistant, wrap-around automatic curling iron structure of this utility model, which facilitates the replacement of curling heads, fixes the heating rod in the handle assembly. A first magnetic positioning structure is provided on the mounting ring, and a second magnetic positioning structure is provided on the curling shell. The second and first magnetic positioning structures are magnetically connected to each other, allowing the curling shell to be installed onto the mounting ring. A first micro-fixing structure is provided on the movable groove, and a second micro-fixing structure is provided on the curling shell. Before installing the curling head, the curling shell is rotated to the position where the first and second micro-fixing structures are attracted to each other, so that the magnetic post structure on the curling shell aligns with the magnetic hole structure on the mounting ring. The drive assembly is driven by the mounting ring, enabling the drive assembly to drive the curling shell to rotate. This curling iron achieves a curling effect by having a second opening at one end of the casing. This opening allows the casing to be fitted onto the heating rod, enabling it to conduct heat and achieve the desired heating effect. When the user needs to curl hair to different degrees, they remove the curling head along the axis of the handle assembly, rotate the curling head's casing until the first and second micro-fixing structures are engaged, and then slide the new curling head onto the heating rod along the axis. When the magnetic pin structure on the curling head is accurately inserted into the magnetic hole structure on the mounting ring, and the two are magnetically connected, the new curling head is in place. This design allows users to create curls of varying degrees efficiently and conveniently, providing a good user experience.

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] Please refer to the following: Figures 1 to 12 This embodiment provides a heat-resistant, wrap-around automatic curling iron structure that facilitates the replacement of the curling head. It includes a handle assembly 100, a mounting ring 200, and a curling head 300. The handle assembly 100 is hollow, with one end having a first opening 130. A drive assembly 110 and a heating rod 120 are disposed within the handle assembly 100. The mounting ring 200 is rotatably mounted within the handle assembly 100 and is drivenly connected to the drive assembly 110. The mounting ring 200 is provided with… The curling head 300 includes a housing 310 and a curling shell 320, with a first magnetic positioning structure. One end of the housing 310 is provided with a second opening 311 so that the housing 310 can be sleeved on the heating rod 120 through the second opening 311. The curling shell 320 is rotatably mounted on the housing 310. The curling shell 320 is provided with a second magnetic positioning structure so that the driving assembly 110 can drive the curling shell 320 to rotate by magnetically connecting the second magnetic positioning structure and the first magnetic positioning structure to each other.

[0037] Among them, one of the first magnetic positioning structure and the second magnetic positioning structure is a magnetic column structure 400, and the other of the first magnetic positioning structure and the second magnetic positioning structure is a magnetic hole structure 500. The magnetic column structure 400 and the magnetic hole structure 500 are arranged correspondingly so that the second magnetic positioning structure and the first magnetic positioning structure are magnetically connected to each other by inserting the magnetic column structure 400 into the magnetic hole structure 500, thereby causing the driving component 110 to drive the curling shell 320 to rotate.

[0038] As can be seen, this embodiment is a curling iron that facilitates the replacement of curling heads with different diameters. The heating rod 120 is fixedly installed in the handle assembly 100. A first magnetic positioning structure is provided on the mounting collar 200, and a second magnetic positioning structure is provided on the curling shell 320. The second and first magnetic positioning structures are magnetically connected to each other, allowing the curling shell 320 to be installed onto the mounting collar 200. The drive assembly 110 is driven by the mounting collar 200, enabling the drive assembly 110 to drive the curling shell 320 to rotate and achieve a curling effect. One end of the shell 310 has a second opening 311, allowing for... The second opening 311 allows the housing 310 to be fitted onto the heating rod 120, enabling the housing 310 to conduct heat from the heating rod 120 and achieve a heating effect. When the user needs to curl hair to different degrees, the curling head 300 is removed along the axis of the handle assembly 100, and the magnetic post structure 400 on the new curling housing 320 is accurately inserted into the magnetic hole structure 500 on the mounting ring 200, with the two magnetically connected to each other. Thus, the new curling head 300 is installed in place. With this setting, the user can curl hair to different degrees, and the curling is efficient, convenient, and provides a good user experience.

[0039] For details, please refer to the following: Figures 1 to 3 The handle assembly 100 includes an upper housing and a lower housing, which are fastened together to form an accommodating space between the upper housing and the lower housing. The diameter of one end of the handle assembly 100 is smaller than the diameter of the other end, so that a hand grip is formed at the end with the smaller diameter, and a first opening 130 is formed at the end with the larger diameter. The opening of the first opening 130 is also provided with a hair curling groove along the axial direction of the handle assembly 100. Optionally, the handle assembly 100 is made of a material that is resistant to high temperature and has poor thermal conductivity to prevent burns, preferably an engineering plastic.

[0040] The design of the magnetic column structure 400 and the magnetic hole structure 500 allows users to complete the installation and disassembly without additional tools or complicated steps, significantly improving replacement efficiency. After the magnetic column structure 400 is inserted into the magnetic hole structure 500, the cooperation between the two can effectively constrain radial and circumferential displacement, ensuring that the torque of the drive component 110 is reliably transmitted to the curling shell 320, and preventing slippage or loosening.

[0041] Preferably, please refer to the following: Figures 1 to 5The magnetic column structure 400 includes a hollow column 410 and a first ferromagnetic element 420. The hollow column 410 is installed on the side of the curling shell 320 facing the mounting collar 200. The first ferromagnetic element 420 is embedded in the hollow column 410. The magnetic hole structure 500 is opened on the side of the mounting collar 200 facing the curling shell 320. A second ferromagnetic element 510 is provided in the magnetic hole structure 500. By inserting the hollow column 410 into the magnetic hole structure 500, and the first ferromagnetic element 420 in the hollow column 410 and the second ferromagnetic element 510 in the magnetic hole structure 500 on the mounting collar 200 are magnetically connected to each other, so as to install the curling head 300 onto the handle assembly 100. This structure is simple and easy to manufacture.

[0042] In this embodiment, please refer to the following: Figures 2 to 3 It also includes a mounting shaft 600, which is installed in the handle assembly 100 and is coaxial with the handle assembly 100. A mounting collar 200 is rotatably fitted onto the mounting shaft 600. One end of the heating rod 120 is connected to the mounting shaft 600. The mounting shaft 600 provides a stable mounting position for the mounting collar 200 and the heating rod 120. By setting a bearing on the mounting shaft 600, the inner ring of the bearing is fixedly connected to the mounting shaft 600, and the outer ring of the bearing is fixedly connected to the mounting collar 200, so that the mounting collar 200 can be rotatably fitted onto the mounting shaft 600. The heating rod 120 has a columnar structure and is coaxial with the mounting shaft 600, and the rotation axis of the mounting collar 200 coincides with the axis of the mounting shaft 600.

[0043] Preferably, such as Figure 4 , Figure 5 and Figure 9 As shown, the housing 310 includes a movable groove 315, and the curling shell 320 is rotatably embedded in the movable groove 315 so that the curling shell 320 can rotate around the axis of the housing 310 under the limitation of the movable groove 315. In addition, the driving component 110 is a motor, which drives the mounting collar 200 to rotate and drives the curling shell 320 to rotate around the axis of the housing 310. The driving connection method and assembly structure between the motor and the mounting collar 200 are existing technologies. Since they are not the key innovative protection points of this solution, they will not be described in detail here. It can be understood that the main innovation of this embodiment lies in the design structure of the curling head 300 and the magnetic disassembly and replacement structure.

[0044] Preferably, please refer to the following: Figures 4 to 5The housing 310 includes a body 312 and an extension rod 313. The body 312 is sleeved on the heating rod 120. One end of the extension rod 313 is screwed to one end of the body 312. The body 312 is usually made of a material with good thermal conductivity and high temperature resistance, preferably aluminum. The excellent thermal conductivity of the body 312 can effectively transfer the temperature of the heating rod 120 to achieve the perming effect. The extension rod 313 is usually made of a material with low thermal conductivity and high temperature resistance, preferably engineering plastic. The body 312 is a hollow columnar structure with open ends. A protruding connecting part is provided at the end of the body 312 away from the mounting ring 200. The outer peripheral surface of the protruding connecting part is provided with external threads. The extension rod 313 is provided with internal threads so that one end of the extension rod 313 can be screwed to the body 312. This connection method is simple and the extension rod 313 is easy to disassemble.

[0045] It should be noted that the function of the extension rod 313 is to guide the hair towards the direction of the main body 312. The extension rod 313 is not necessary. The attraction of the first magnetic positioning structure and the second magnetic positioning structure is sufficient to maintain the stability of the curling head 300 during the curling process, and the curling head 300 will not fall off accidentally. Since the extension rod 313 is made of engineering plastic, the extension rod 313 will not get hot to the touch. The user can directly hold the extension rod 313 and apply an axial outward force to remove the curling head 300.

[0046] In this embodiment, the other end of the extension rod 313 extends through the handle assembly 100 through the first opening 130, and the extension length of the other end of the extension rod 313 through the first opening 130 is 4cm, 8cm or 12cm. With this setting, the extension rod 313 can better guide the hair in the direction of the body 312, making hair perming convenient and highly practical.

[0047] In this embodiment, as Figures 2 to 5 The outer peripheral surface of the heating rod 120 is provided with a first limiting structure 121, and the inner peripheral surface of the shell 310 is provided with a second limiting structure 314. The shell 310 is slidably fitted onto the heating rod 120. The first limiting structure 121 and the second limiting structure 314 can engage with each other so that the shell 310 and the heating rod 120 cannot rotate relative to each other. The first limiting structure 121 is a strip groove, which is provided on the outer peripheral surface of the heating rod 120 and extends along the length direction of the heating rod 120. The second limiting structure 314 is a strip protrusion, which is provided on the inner peripheral surface of the shell 310 and extends along the length direction of the shell 310.

[0048] In this embodiment, as Figures 6 to 12As shown, a first micro-fixing structure 700 is provided on the movable slot 315, and a second micro-fixing structure 800 corresponding to the first micro-fixing structure 700 is provided on the curling shell 320. When the curling head 300 is disassembled and replaced, the curling shell 320 is rotated to a position where the first micro-fixing structure 700 and the second micro-fixing structure 800 are attracted to each other, so that the curling shell 320 cannot rotate arbitrarily on the movable slot 315. When the first micro-fixing structure 700 and the second micro-fixing structure 800 are attracted to each other, no accidental relative rotation will occur between the curling shell 320 and the movable slot 315. When the curling iron is working, because the curling shell 320 and the movable slot 315 are magnetically positioned by the first micro-fixing structure 700 and the second micro-fixing structure 800, the curling shell 320 can rotate on the movable slot 315 without affecting its curling function.

[0049] In this embodiment, as Figures 6 to 12 As shown, there are two first micro-fixing structures 700, which are circumferentially spaced within the lower wall of the movable groove 315. There are also two second micro-fixing structures 800. The multiple first micro-fixing structures 700 and multiple second micro-fixing structures 800 of the curling head to be installed are not usually attracted in a one-to-one correspondence. It can be understood that when the first micro-fixing structures 700 and the second micro-fixing structures 800 are attracted together, the curling shell 320 needs sufficient rotational force to separate the first micro-fixing structures 700 and the second micro-fixing structures 800 from each other. When the rotational force is insufficient to separate the first micro-fixing structures 700 and the second micro-fixing structures 800 from each other, the curling shell 320 is restricted in its positioning, that is, the curling shell 320 cannot rotate freely to achieve positioning.

[0050] In this embodiment, the first micro-fixed structure 700 includes a rolling groove 710 and a magnetic ball 720. The rolling groove 710 is formed in the lower groove wall of the movable groove 315, and the magnetic ball 720 can roll in the rolling groove 710. The second micro-fixed structure 800 includes an embedding groove 810 and a third ferromagnetic component 820. The embedding groove 810 is formed circumferentially on the inner circumferential surface of the curling shell 320, and the third ferromagnetic component 820 is embedded in the embedding groove 810. By rotating the curling shell 320, the third ferromagnetic component 820 can be attracted to the magnetic ball 720.

[0051] Furthermore, this embodiment also has a stop-rotation and return-to-position structure, which can stop the installation collar 200 from rotating to a specific position after the user releases the rotation button. To facilitate understanding of this utility model, the replacement process of the curling shell 320 is also explained. First, stop the rotation and return structure to allow the mounting collar 200 to rotate to a specific position and stop. The user removes the curling head 300 to be disassembled along the axis of the handle assembly 100. Then, adjust the curling shell 320 of the curling head 300 of the required diameter to the position where the first micro-fixing structure 700 and the second micro-fixing structure 800 are attracted together. Guided by the strip groove of the first limiting structure 121 and the strip protrusion of the second limiting structure 314, slide the curling head 300 of the required diameter into the handle assembly 100 along the axis. The curling shell 320 is restricted and positioned by the attraction of the first micro-fixing structure 700 and the second micro-fixing structure 800. The magnetic suction column structure 400 below it forms a circumferential fixed angle with the strip protrusion of the second limiting structure 314. The mounting collar... When the stop-rotation return structure and the strip groove of the first limiting structure 121 are at a fixed circumferential angle, all magnetic column structures 400 and all corresponding magnetic hole structures 500 are longitudinally aligned. When the curling head 300 slides into the handle assembly 100 along the axial direction and the first limiting structure 121 and the second limiting structure 314 engage with each other, all the magnetic column structures 400 below it are longitudinally aligned with all the corresponding magnetic hole structures 500 on the mounting collar 200 and inserted. When the first ferromagnetic part 420 on the magnetic column structure 400 and the second ferromagnetic part 510 in the magnetic hole structure 500 on the mounting collar 200 come close to each other, a "click" magnetic contact sound will be produced, indicating that the curling head 300 has been accurately installed in place. This completes the installation process. This setting eliminates the need for installation and calibration, improving the portability of replacing the curling head 300.

[0052] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0053] By fixing the heating rod 120 to the handle assembly 100, a first magnetic positioning structure is provided on the mounting collar 200, and a second magnetic positioning structure is provided on the curling shell 320. The second and first magnetic positioning structures are magnetically connected to each other, allowing the curling head 300 to be accurately mounted onto the mounting collar 200. A drive assembly is driven by the mounting collar 200, enabling the drive assembly 110 to drive the curling shell 320 to rotate and achieve a curling effect. One end of the shell 310 has a second opening 311. The second opening 311 allows the housing 310 to be fitted onto the heating rod 120, enabling the housing 310 to conduct heat from the heating rod 120 and achieve a heating effect. When the user needs to curl hair to different degrees, the curling head 300 can be removed along the axis of the handle assembly 100, and a new curling head 300 can be installed along the axis of the handle assembly 100, thus achieving the effect of changing the curling head 300. With this setting, the user can curl hair to different degrees, which is efficient, convenient, and provides a good user experience.
