Abstract
Description
Technical Field
[0001] This utility model relates to the field of hair curling equipment, and more particularly to an automatic hair curler. Background Technology
[0002] A curling iron is a hair styling tool used to turn straight hair into curls. It typically consists of a heated cylindrical metal or ceramic rod and a handle. To use it, hair is wrapped around the heated cylinder to achieve a curl. However, most existing curling irons use a heat transfer method where the heating element is held between two heat-conducting aluminum supports, which has several drawbacks: complex assembly, low production efficiency, high defect rate, high cost, slow heat transfer, and unsatisfactory curling results. Furthermore, the existing curling irons have a flat front slot design, requiring manual fixing of the hair in the slot before pressing a rotation switch to allow the curling claws to wrap the hair around the cylinder for setting. This design results in inconvenient operation and poor styling results. Utility Model Content
[0003] To address the aforementioned technical problems, the purpose of this utility model is to provide an automatic hair curler. By integrating two heat-transfer aluminum brackets into a single heat-transfer bracket structure for fixing the heating module, efficient heat transfer is achieved. This not only significantly simplifies the assembly process, improves production efficiency, and reduces production costs, but also allows the integrated heat-transfer bracket to transfer heat faster, providing a more uniform heat distribution and significantly improving the curling effect.
[0004] To achieve the above objectives, this utility model provides an automatic hair curler, including a hair curling component and a heating component. The heating component is disposed inside the hair curling component. The heating component includes an integrally formed heat transfer bracket and a heating module. The heat transfer bracket is provided with a mounting cavity having an installation opening. The heating module is adapted to be placed in the mounting cavity after passing through the installation opening.
[0005] In some embodiments, the heat transfer bracket includes a first body, a second body, and a third body. The first body and the second body are symmetrically arranged at both ends of the third body. The third body connects the same ends of the first body and the second body and is arranged opposite to the mounting port.
[0006] In some embodiments, a heat transfer sleeve is also included, which is sleeved on the outside of the heat transfer support.
[0007] Both the first body and the second body include a curved portion and a horizontal portion, and the mounting cavity is formed between adjacent horizontal portions. The curved portion is located on the side of the horizontal portion away from the third body and is adapted to the inner wall of the heat transfer sleeve.
[0008] In some embodiments, the curved portion is further provided with an elastic notch in the middle.
[0009] In some embodiments, the hair curling assembly includes a hair curling section, a rotating mechanism, and a plurality of rotating sections, the plurality of rotating sections being arranged around the outside of the hair curling section, the heating assembly being provided inside the hair curling section, and the rotating mechanism being adapted to drive the rotating sections to rotate.
[0010] In some embodiments, the top of the curling section is provided with a snap-fit groove, the bottom of the snap-fit groove is provided with an inclined portion, and the inclined portion is inclined toward the side closer to the heating component, so that the hair is suitable for being rolled into the rotating section.
[0011] In some embodiments, the inclined portion includes an inclined surface that extends radially along the curling portion and is inclined toward the side closer to the heating assembly.
[0012] In some embodiments, the inclined portion includes a pair of inclined surfaces, both of which extend inclinedly from the center point of the snap-fit groove toward the side closer to the heating assembly.
[0013] In some embodiments, a movable part is also included, which is movably connected to the bottom of the inclined part and the bottom of the snap-fit groove, so that the tilt angle of the inclined part can be adjusted arbitrarily.
[0014] In some embodiments, at least one of the rotating portions has a protrusion on its inner side, the protrusion being adapted to extend radially along the curling portion toward the side closer to the heating assembly.
[0015] Compared with the prior art, the automatic hair curler provided by this utility model has at least one of the following beneficial effects:
[0016] 1. By integrating two heat transfer aluminum brackets into a single heat transfer bracket structure to fix the heating module, efficient heat transfer is achieved. This not only significantly simplifies the assembly process, improves production efficiency, and reduces production costs, but also allows the integrated heat transfer bracket to transfer heat faster, providing a more uniform heat distribution and significantly improving the curling effect.
[0017] 2. The bottom of the groove is provided with an inclined part, which is tilted towards the side closer to the heating component. This allows the hair to be rolled into the rotating part more naturally during the winding process, avoiding tangling or getting stuck, thereby improving the curling effect and user experience.
[0018] 3. The raised part reduces the distance between the rotating part and the heat transfer sleeve, ensuring that the hair can fit tightly against the heat transfer sleeve during the curling process, thereby achieving a more even and longer-lasting curling effect. Attached Figure Description

It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
[0034] refer to Figure 1 and Figure 2 This utility model provides an automatic hair curler, including a hair curling component 1 and a heating component 2. The heating component 2 is disposed inside the hair curling component 1. The heating component 2 includes an integrally formed heat transfer bracket 21 and a heating module 22. The heat transfer bracket 21 is provided with a mounting cavity 210 having a mounting port 2131. The heating module 22 is adapted to be placed in the mounting cavity 210 after passing through the mounting port 2131.
[0035] In this embodiment, by integrating two heat-transfer aluminum brackets into an integrated heat-transfer bracket 21 structure to fix the heating module 22, efficient heat transfer is achieved. This not only significantly simplifies the assembly process, improves production efficiency, and reduces production costs, but also the integrated heat-transfer bracket 21 has a faster heat transfer speed and can provide a more uniform heat distribution, significantly improving the curling effect.
[0036] Specifically, the heating component 2 is located inside the curling component 1 and consists of an integrally molded heat transfer bracket 21 and a heating module 22. The heat transfer bracket 21 has a mounting cavity 210 with a mounting port 2131, through which the heating module 22 can be installed into the mounting cavity 210. By designing the heat transfer bracket 21 as an integral unit, the number of parts and assembly steps can be reduced, production difficulty can be lowered, production efficiency can be improved, and the defect rate caused by improper assembly can be reduced. Moreover, through the integrated design, the heat transfer bracket 21 can reduce production costs while ensuring performance, thereby improving the product's market competitiveness.
[0037] Preferably, refer to Figure 2 and Figure 3 The heat transfer bracket 21 includes a first body 211, a second body 212, and a third body 213. The first body 211 and the second body 212 are symmetrically arranged at both ends of the third body 213. The third body 213 connects to the same ends of the first body 211 and the second body 212 and is positioned opposite to the mounting port 2131. The first body 211 and the second body 212 are located at opposite ends of the third body 213 and are symmetrically distributed vertically. The connection of the third body 213 to the same ends of the first body 211 and the second body 212 ensures the stability of the overall structure. Simultaneously, its relative position to the mounting port 2131 facilitates the installation and fixation of the heating module 22, optimizing the layout and function of the heat transfer bracket 21 and enabling it to play a more efficient role in the automatic hair curler. At this point, the first main body 211, the second main body 212, and the third main body 213 together form the mounting cavity 210. During installation, the heating module 22 is simply placed into the mounting cavity 210 through the mounting port 2131. The heating module 22 then abuts against the inner wall of the mounting cavity 210. It is worth noting that a limiting block can also be installed inside the mounting cavity 210 according to the size of the heating module 22. The limiting block prevents the heating module 22 from moving arbitrarily.
[0038] Furthermore, it also includes a heat transfer sleeve 23, which is sleeved on the outside of the heat transfer bracket 21; the first body 211 and the second body 212 both include an arcuate portion 2111 and a horizontal portion 2112, and an installation cavity 210 is formed between adjacent horizontal portions 2112. The arcuate portion 2111 is located on the side of the horizontal portion 2112 away from the third body 213 and is adapted to the inner wall of the heat transfer sleeve 23.
[0039] Specifically, the heat transfer sleeve 23 is fitted onto the outside of the heat transfer bracket 21 to fix and protect the heat transfer bracket 21, while also providing structural support. Both the first body 211 and the second body 212 include an arc-shaped portion 2111 and a horizontal portion 2112. The arc-shaped portion 2111 is designed to match the shape of the hair curling component 1, thereby better conforming to the hair and achieving a curling effect. The horizontal portion 2112 has a planar structure, and an installation cavity 210 is formed between adjacent horizontal portions 2112 to accommodate the heating module 22. The arc-shaped portion 2111 is located on the side of the horizontal portion 2112 away from the third body 213 and is adapted to the inner wall of the heat transfer sleeve 23, ensuring that the heat transfer bracket 21 is stably installed within the heat transfer sleeve 23, while ensuring that heat can be evenly conducted to the hair curling component 1, improving the curling effect and safety of use.
[0040] Preferably, the curved portion 2111 also has an elastic notch 2113 in the middle. This elastic notch 2113 effectively absorbs and disperses stress concentration generated during use, thereby improving the elasticity and toughness of the heat transfer bracket 21. This structure prevents material fatigue and fracture caused by stress concentration, while enhancing the adaptability and durability of the heat transfer bracket 21 during hair curling operations. Furthermore, the elastic notch 2113 optimizes the elastic modulus of the heat transfer bracket 21, allowing it to better recover its original shape after being subjected to force. The heat transfer sleeve 23 also has an abutment portion at the location of the elastic notch 2113. This abutment portion cooperates with the elastic notch 2113 to provide additional structural support for the heat transfer sleeve 23, preventing deformation or displacement caused by external forces during use, ensuring a tighter overall structure after assembly, and reducing heat loss or structural loosening due to assembly errors. It also limits the maximum deformation of the elastic notch 2113, preventing the elastic structure from losing elasticity due to excessive stretching or compression, thereby extending its service life.
[0041] Further, refer to Figure 1 and Figure 4 The hair curling assembly 1 includes a curling section 11, a rotating mechanism 12, and several rotating sections 13. The rotating sections 13 are arranged around the outside of the curling section 11, and a heating component 2 is provided inside the curling section 11. The rotating mechanism 12 is adapted to drive the rotating sections 13 to rotate. Specifically, the hair curling assembly 1 includes a curling section 11, a rotating mechanism 12, and several rotating sections 13. The rotating sections 13 are arranged around the outside of the curling section 11 to evenly curl the hair around it. The heating component 2 is provided inside the curling section 11 to provide heat support for the curling process. The rotating mechanism 12 is adapted to drive the rotating sections 13 to rotate, achieving automatic curling via a motor or other power device. This design not only improves curling efficiency but also reduces the inconvenience of manual operation, while ensuring a more even and long-lasting curling effect.
[0042] Preferably, the top of the curling part 11 is provided with a snap-fit groove 111, and the bottom of the snap-fit groove 111 is provided with an inclined part 112. The inclined part 112 is inclined towards the side closer to the heating component 2, so that the hair is suitable for being rolled into the rotating part 13.
[0043] In this embodiment, the bottom of the snap-fit groove 111 is provided with an inclined portion 112. The inclined portion 112 is inclined towards the side closer to the heating component 2, so that the hair can be rolled into the rotating part 13 more naturally during the winding process, avoiding the hair from getting tangled or stuck during the winding process, thereby improving the curling effect and user experience.
[0044] Specifically, in use, hair is placed into the slot 111 of the curling section 11, and the rotation switch is pressed. The rotating section 13 tightly wraps the hair around the heating component 2, allowing the hair to be quickly styled. (Reference) Figure 5 The inclined section 112 includes an inclined surface 1121, which extends radially along the curling section 11 and is inclined towards the side closer to the heating component 2. The inclined surface 1121 has a certain angle, and the length of the rotating section 13 ensures that the hair is automatically rolled into the rotating section 13, greatly freeing users from manually inserting the hair into the rotating section 13, making it convenient for operation. In other words, the inclined surface 1121 effectively guides the hair to naturally roll into the rotating section 13 during the curling process, preventing tangling or jamming, thereby improving the smoothness of the curl and the user experience. Guided by the inclined surface 1121, the hair can fit more closely to the curling section 11 and the rotating section 13, making the curling effect more even and lasting. This design reduces the problem of poor curling effect caused by uneven heating of the hair, optimizes the direction of heat conduction, and makes the heat more evenly transferred to the hair, reducing local overheating or insufficient temperature, thus protecting the hair from heat damage. Furthermore, the inclined surface 1121, combined with the airflow guiding function of the curling section 11, can make the hair smoother during the curling process and reduce frizz and flyaways.
[0045] In a modified embodiment, the inclined portion 112 includes a pair of inclined surfaces 1121, both of which extend inclinedly from the center point of the snap-fit groove 111 toward the side closer to the heating component 2.
[0046] In this embodiment, a pair of inclined surfaces 1121 extend from the center point of the snap-fit groove 111 to one side of the heating component 2, which can effectively guide the hair to naturally roll into the rotating part 13 during the curling process, ensuring the structural consistency of the curling device when used on both sides.
[0047] Specifically, a pair of inclined surfaces 1121 extend symmetrically from the center point of the slot 111. Guided by the inclined surfaces 1121, hair can be smoothly rolled into the rotating part 13 from different directions. Whether operated from the front or back, multi-angle curling effects can be achieved, allowing users to operate flexibly according to hair length and curling needs. This reduces the difficulty of operation during the curling process, making it especially suitable for users with different hand-holding habits, further enhancing the curling experience. The symmetrical inclined surface 1121 design also reduces the time users spend adjusting the device's direction, improving curling efficiency. It can also distribute stress, reducing damage caused by excessive localized force during use, ensuring even force distribution on the hair during the curling process, and reducing the possibility of curling failure. Moreover, the inclined surfaces 1121 not only guide the hair into the rotating part 13 but also optimize the airflow direction, allowing hot or cold air to be more evenly distributed on the hair.
[0048] It is worth noting that the symmetrical arrangement of a pair of inclined surfaces 1121 on the inclined portion 112 not only improves the flexibility and efficiency of the hair curling device, but also further enhances the curling effect and user experience.
[0049] In another modified embodiment, a movable part is also included, which is movably connected to the bottom of the inclined part 112 and the bottom of the snap-fit groove 111, so that the tilt angle of the inclined part 112 can be adjusted arbitrarily.
[0050] In this embodiment, the movable part and the tilting part 112 are connected to each other, so that the hair curler can not only realize multi-angle adjustment function, but also significantly improve the curling effect and user experience, while taking into account safety and durability.
[0051] Specifically, the movable part is connected to the bottom of the tilting part 112 via a hinge, sliding, or other movable connection method, ensuring that the tilting part 112 can freely adjust its angle within a certain range. This connection method may also include an elastic element (such as a spring) or a limiting structure to provide stable support and angle positioning. The elastic element can absorb some external force, reducing damage to the device due to collisions or improper operation, and extending the service life of the device. The specific connection structure between the movable part and the tilting part 112 is diverse, and will not be elaborated further here, as long as it can achieve free adjustment of the tilting surface 1121. Through the adjustment function of the movable part, the tilting part 112 can achieve multi-angle changes from horizontal to a certain tilt angle, so that the tilt angle of the tilting part 112 can be arbitrarily adjusted according to the user's needs, suitable for hair of different lengths and curls, so that the curling iron can better fit the hair quality and hairstyle needs of different users, achieving a more even and long-lasting curling effect. Users can freely adjust the angle of the tilt section 112 according to the length of their hair and the desired curl. Users can choose the most suitable angle based on their hand holding habits or ease of operation, so that the curling iron can be used on both sides, thereby optimizing the curling process and meeting diverse curling needs.
[0052] Further, refer to Figure 6 At least one rotating part 13 has a protrusion 131 on its inner side, and the protrusion 131 is adapted to extend radially along the curling part 11 toward the side close to the heating component 2.
[0053] In this embodiment, the protrusion 131 reduces the distance between the rotating part 13 and the heat transfer sleeve 23, ensuring that the hair can fit tightly against the heat transfer sleeve 23 during the curling process, thereby achieving a more uniform and longer-lasting curling effect.
[0054] Specifically, the protrusion 131 is located inside the rotating part 13, extending radially along the curling part 11 and protruding towards the side near the heating component 2 (such as the heat transfer sleeve 23). Its shape can be circular, semi-circular, triangular, or other suitable shapes, depending on the overall structure and functional requirements of the curling iron. The protrusion 131 ensures that the hair is stably guided to adhere closely to the curling part 11 during rotation. By optimizing the contact area between the hair and the heat transfer sleeve 23, the protrusion 131 significantly improves the curling effect, making the curls more natural and beautiful. The protrusion 131 minimizes the distance between the rotating part 13 and the heat transfer sleeve 23, thereby reducing heat loss during conduction and allowing heat to be transferred to the hair more efficiently. This not only improves curling efficiency but also reduces the problem of poor curling results due to localized overheating or insufficient temperature. Simultaneously, the protrusion 131 better guides the hair to adhere closely to the heat transfer sleeve 23, ensuring even heating of the hair during the curling process. Preferably, the surface of the protrusion 131 can be designed to be smooth or have a slight texture to further optimize the curling effect of the hair.
[0055] It is worth noting that, in modified embodiments, the protrusion 131 can also be made of a soft and elastic material, which can reduce pulling and friction on the hair, avoid hair breakage or damage caused by external force during the curling process, and further improve the comfort of the curling process. In another embodiment, the protrusion 131 can be detachably installed on the inside of the rotating part 13, allowing users to choose rotating parts 13 with protrusions 131 of different shapes or heights according to their hair type and curling needs, further improving the flexibility of curling.
[0056] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of this utility model. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
