[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 5 As shown, this utility model provides an easy-to-assemble automatic hair curler, mainly comprising three modules: a handle 1, a heating component 2, and a curling cylinder component 3. This hair curler adopts a modular design, with each component combined together through a simple connection method, greatly reducing assembly difficulty and improving production efficiency.

[0026] The handle 1 serves as the grip and core control component of the hair curler, housing a connector 4, a circuit board 5, and a geared motor 6. The connector 4 is made of high-strength engineering plastic, offering excellent insulation and heat resistance. The circuit board 5, installed in a suitable location inside the handle 1, is responsible for the electronic control of the entire hair curler, including temperature control, motor drive, and safety protection functions. The geared motor 6, fixedly installed inside the handle 1, serves as the power source for the curling cylinder assembly 3, enabling smooth rotation of the cylinder.

[0027] The heating assembly 2 is fixedly connected to the handle 1, including an inner tube 21 fixedly connected to the connecting seat 4 and a heating element 22 disposed in the inner tube 21. The inner tube 21 is made of a metal material with good thermal conductivity, such as an aluminum tube. The heating element 22 is embedded inside the inner tube 21, which can heat up quickly and maintain a stable temperature to ensure the curling effect.

[0028] The curling assembly 3 is rotatably connected to the handle 1 to form a rotatable hair curling section, including a collar 31, an outer tube 32 (such as an aluminum tube) fixed to the collar 31 and fitted onto the inner tube 21, and a hair clamping structure 33 provided on the outer tube 32. The collar 31 is rotatably connected to the connecting seat 4 via a first bearing 34, enabling smooth rotation of the collar 31 relative to the handle 1. The outer end of the outer tube 32 is rotatably connected to the outer end of the inner tube 21 via a second bearing 35, ensuring the overall stability and smooth rotation of the curling assembly 3.

[0029] This utility model features a dual-bearing support system: a first bearing connects the collar and the connecting seat, while a second bearing connects the outer tube and the outer end of the inner tube, forming a double-support structure to ensure smooth rotation and structural stability of the drum assembly. The coaxial nested tube design: through a coaxial nested design where the inner tube is fixed and the outer tube rotates, the heating and rotation functions are effectively separated while maintaining a compact structure.

[0030] A gear and ring drive structure is provided between the output end of the geared motor 6 and the collar 31, realizing efficient transmission of motor power. Specifically, as follows: Figure 2 , 4 As shown, the gear and ring transmission structure includes an external gear 61 mounted on the output shaft of the geared motor 6, and an internal gear ring 36 mounted on the inner wall of the collar 31 and meshing with the external gear 61. This transmission structure design makes power transmission more direct, reduces transmission losses, and simplifies the assembly process.

[0031] To facilitate assembly and maintenance, a stepped hole 311 is provided at the inner end of the collar 31, consisting of two parts with different diameters. The first bearing 34 and the internal gear ring 36 are sequentially inserted into the stepped hole 311, with the internal gear ring 36 located on the side of the first bearing 34 closer to the handle 1. This design allows the components to be installed in a specific order, enabling assembly without the need for complex tools.

[0032] like Figure 2 , 5As shown, the outer end of the inner tube 21 is provided with a top cover 23, which is fixedly connected to the connecting seat 4. The top cover 23 has a mounting groove 231 at its center for fixing the second bearing 35, and a screw seat 37 is connected to the center of the second bearing 35. The outer end of the outer tube 32 is provided with a rotating head 38, which has a first through hole 381 at its center. A connector 382 (e.g., a bolt) is provided in the first through hole 381, and the connector 382 is threadedly connected to the screw seat 37. This connection method not only ensures the rotational stability of the outer tube 32 but also facilitates disassembly and maintenance when necessary.

[0033] To further improve the durability and safety of the product, a fixing cover 24 is provided at the outer end of the top cover 23 to block the second bearing 35 from the outside. The fixing cover 24 has a second through hole 241 at its center for the screw seat 37 to pass through, and its diameter is smaller than that of the second bearing 35. The fixing cover 24 and the top cover 23 are fixedly connected. This design effectively prevents the second bearing 35 from loosening or falling off during use, thus improving the safety performance of the product.

[0034] The outer end of the rotating head 38 is detachably connected (e.g., snap-fit) to a rotating cap 39, allowing users to easily change different types of rotating caps according to different hair types and styling needs, increasing the product's applicability and flexibility. The rotating cap 39 is easy to disassemble for maintenance or replacement.

[0035] The hair-clamping structure 33 of this utility model includes a hair-clamping button 331 rotatably connected to a collar 31 in the middle. One end of the hair-clamping button 331 is provided with a hair-clamping gel 332, made of a high-temperature resistant flexible material (such as silicone), which can gently clamp the hair without damaging the hair. The other end of the hair-clamping button 331 is provided with a pressing part 3311, which allows the user to apply pressure to operate the hair-clamping button. A return spring 333 is provided between the hair-clamping button 331 and the collar 31, which can promote the hair-clamping gel 332 to fit against the outer wall of the outer tube 32, ensuring that the hair is firmly clamped. This design allows users to easily clamp their hair into the curling iron for styling, with simple operation and good results.

[0036] To achieve intelligent control of the automatic hair curling function, at least one magnet 7 is provided around the periphery of the collar 31, and a Hall sensor 51 capable of detecting the position of the magnet 7 is provided at the corresponding position of the connecting seat 4. The Hall sensor 51 is electrically connected to the circuit board 5. By detecting the position change of the magnet 7, the system can accurately determine the rotation state and position of the roller, thereby achieving precise rotation control and avoiding problems such as hair tangling or damage caused by excessive rotation.

[0037] In summary, this utility model provides a compact, easy-to-assemble, and highly efficient automatic hair curler, solving the problems of complex assembly, loose structure, and inconvenience in use of traditional hair curlers, and has high practical value. The easy-to-assemble automatic hair curler provided by this utility model significantly reduces assembly difficulty through modular design and simplified connection methods, while ensuring product stability and safety. This hair curler is not only easy to operate but also achieves intelligent automatic hair curling function, meeting the growing hair styling needs of users.
