Simultaneously, the curling accessory utilizes an independent, enclosed mounting cavity built inside the body, combined with a non-linear air passage airflow guidance design. This ensures that high-temperature airflow flows from the air inlet through a reversible non-linear channel to the air outlet of the curling component. The drive unit remains within a sealed cavity free from hot air interference throughout the process, achieving zero intersection and zero thermal coupling between the hot air path and the power system path. This achieves the technical effect of maintaining efficient curling and drying functions while completely avoiding performance degradation of the drive unit due to high-temperature aging, insulation deterioration, or torque attenuation.

[0058] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0059] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0060] In this invention, unless otherwise stated, directional terms such as "up" and "down" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0061] In order to solve the problem that the motor driving the curling iron or rotating dial is located in the hot air flow channel in the prior art, which affects its service life and poses a safety hazard, this application provides a curling accessory and a curling iron having the same.

[0062] like Figures 1 to 18 As shown, the hair curling accessory includes a body 10, a connecting seat 30, a drive unit 70, and a hair curling assembly 40. The body 10 has an air passage 11, the air inlet 111 of which communicates with the hot air outlet of a heating air supply device 20. The air passage 11 is a non-linear passage. The connecting seat 30 is disposed on the body 10 and located at the air inlet 111 of the air passage 11, and is used to connect to the heating air supply device 20. The drive unit 70 is disposed inside the body 10. The hair curling assembly 40 is disposed on the body 10; the drive unit 70 is drivenly connected to at least a portion of the hair curling assembly 40 to drive that portion of the hair curling assembly 40 to rotate and thus curl the hair; the hair curling assembly 40 has an air outlet 412 communicating with the air outlet 112 of the air passage 11, and the hot air blown from the air outlet 412 is used to heat the hair curled on the hair curling assembly 40. The body 10 also has a mounting cavity 12, and the drive device 70 is installed in the mounting cavity 12. The mounting cavity 12 and the air passage 11 are set independently of each other.

[0063] By applying the technical solution of this embodiment, the drive device 70 is independently set in the mounting cavity 12, which is completely isolated from the air passage 11, so that the hot air passage (air passage 11) and the working area of ​​the drive device 70 are completely separated in physical structure. Furthermore, the air passage 11 adopts a non-linear layout to block the heat conduction path, thereby effectively isolating the drive device from direct heat radiation and convection heating by high-temperature hot air. This significantly reduces the working environment temperature of the drive device 70, extends its service life, and improves operational safety. In turn, it solves the problem in the prior art where the motor driving the curling iron or rotating paddle is located in the hot air passage, which affects its service life and poses safety hazards. Meanwhile, the hair curling accessory adopts an independent and closed mounting cavity 12 built inside the body 10 and an airflow guiding design with a non-linear air passage 11 to ensure that the high-temperature airflow flows from the air inlet 111 through the folding non-linear channel to the air outlet 412 of the hair curling component 40. The drive device 70 is in a sealed cavity without hot air interference throughout the process, which achieves the purpose of zero intersection and zero thermal coupling between the hot air path and the power system path. This achieves the technical effect of completely avoiding the performance degradation of the drive device 70 due to high temperature aging, insulation deterioration or torque attenuation while maintaining efficient hair curling and drying functions.

[0064] like Figure 8 As shown, the air passage 11 includes an air inlet section 113 and an air outlet section 114. The first end of the air inlet section 113 is an air inlet 111. The second end of the air inlet section 113 is connected to the first end of the air outlet section 114, and the second end of the air outlet section 114 is an air outlet 112. The air inlet direction of the air inlet 111 and the air outlet direction of the air outlet 112 are set at an angle. In this way, by designing the air passage 11 as a segmented non-linear flow channel with an angled turning structure, the hot air from the heating air device 20 enters from the air inlet 111 along a first preset direction, turns through the air inlet section 113, and is guided along the air outlet section 114 at an angle to the inlet to the air outlet 412 of the curling assembly 40. This effectively blocks the direct reverse conduction of high-temperature airflow along a straight path to the internal drive device area, thereby significantly reducing the thermal impact of hot air recirculation or thermal radiation on the drive device inside the mounting cavity.

[0065] In this embodiment, a non-collinear angle airflow turning structure is formed between the air inlet section 113 and the air outlet section 114. By utilizing the inertia and turbulence effect of the airflow at the bend, the local dissipation and direction reconstruction of hot air energy are achieved. At the same time, the air outlet section 114 is precisely aligned with the air outlet 412 of the hair curling component 40 to optimize the hot air utilization rate. This achieves the dual optimization of directional hot air output and thermal isolation without increasing wind resistance, thereby improving the hot air utilization efficiency, reducing the ineffective accumulation of heat inside the machine, and reducing the temperature rise of the entire machine surface.

[0066] Optionally, the inner diameter of the air inlet section 113 gradually decreases along the flow direction of the hot air; and / or the inner diameter of the air outlet section 114 remains unchanged. In this way, by designing the air inlet section 113 as a tapered flow channel and maintaining a constant inner diameter of the air outlet section 114, the gradual contraction of the inner diameter of the air inlet section 113 accelerates and concentrates the pressure of the hot air, allowing the airflow to gain higher kinetic energy before entering the air outlet section 114. Simultaneously, the constant cross-section of the air outlet section 114 maintains stable airflow output, avoiding eddies and energy loss. This achieves the goal of improving the transmission efficiency and dynamic pressure utilization of the hot air from the air inlet to the air outlet, thereby reducing the power load of the heating device and enhancing the penetration and heating uniformity of the hot air into the hair under the same airflow requirement.

[0067] In this embodiment, along the flow direction of hot air in the inlet section 113, the inner diameter of the inlet section 113 gradually decreases, while the inner diameter of the outlet section 114 remains unchanged. This segmented air duct structure design, with a gradually decreasing inlet section and a constant diameter outlet section, achieves pre-compression and acceleration of the airflow in the inlet section 113, allowing the high-speed airflow to smoothly transition to the constant-diameter outlet section 114. In the outlet section 114, a constant flow velocity is maintained, directly acting on the outlet part 412 of the curling component 40. This optimizes airflow dynamics, reduces turbulence and heat loss, and ensures concentrated and directional output of hot air. Consequently, it significantly improves the heat transfer efficiency of hot air on the curled hair per unit time, shortens the perming time, and reduces the risk of localized overheating.

[0068] like Figure 1 , Figure 2 as well as Figure 4 As shown, the hair curling assembly 40 includes a curling iron 41 and a rotating paddle 42. The curling iron 41 has a first mounting opening 411 and an air outlet 412, the air outlet 412 communicating with the air outlet section 114. The rotating paddle 42 is disposed around the curling iron 41 to form a ventilation gap communicating with the air outlet 412, and the rotating paddle 42 has a first side notch 421; a drive device 70 is drivenly connected to the rotating paddle 42 to drive the rotating paddle 42 to rotate around the central axis of the curling iron 41. Both the first mounting opening 411 and the first side notch 421 are used for hair to enter. In this way, the curling iron 41 and the rotating pick 42 are designed as a cooperating curling structure with a concentric ventilation gap and a first side notch 421. When the rotating pick 42 rotates around the curling iron 41, an annular ventilation gap is formed between them. The hot air connected to the air outlet 412 can be evenly sprayed onto the surface of the curled hair along the gap. At the same time, the first side notch 421 on the rotating pick 42 and the first mounting port 411 of the curling iron 41 form an aligned hair inlet channel, which achieves the goal of realizing the integrated operation process of "single insertion, automatic winding, and dynamic heating" of hair. This achieves the technical effect of significantly improving curling efficiency, reducing manual intervention, and ensuring that hot air is evenly covered from the root to the end of the hair.

[0069] In this embodiment, the rotating paddle 42 and the curling iron 41 are not rigidly connected. A ring-shaped hot air channel is formed between them through a gap, and the dynamic entry method is achieved in conjunction with the first side notch 421. When the rotating paddle 42 is driven by the driving device 70, its first side notch 421 is periodically aligned with the first mounting port 411 of the curling iron 41, forming a synchronous channel for "entry, winding, and heating" that is opened momentarily. The hot air forms a spiral airflow field as the rotating paddle 42 rotates in the ventilation gap, which achieves the purpose of continuously, stably, and from multiple angles applying heat to the hair during the curling process, while avoiding the hair from being stuck or tangled on the fixed parts. This achieves the technical effects of improving the smoothness of the curl, reducing the operating resistance, and enhancing the consistency and naturalness of the perm.

[0070] like Figure 10 and Figure 11 As shown, the curling iron 41 includes a ventilation structure 413, a curling barrel 414, and a clamping plate structure 415. The ventilation structure 413 has a ventilation section 4131, which is connected to the first end of the curling barrel 414. An air outlet 412 is disposed on the barrel wall of the curling barrel 414, and the ventilation section 4131 communicates with the air outlet 412 through the inner cavity of the curling barrel 414. The clamping plate structure 415 is connected to the second end of the curling barrel 414 and has a first mounting port 411. The air outlet 412 includes a plurality of air outlet holes spaced apart along the axial direction and / or circumferential direction of the curling barrel 414, and the extending direction of the air outlet section 114 is consistent with the axial direction of the curling barrel 414. Thus, the curling iron 41 has a three-section split structure: air passage structure 413, curling barrel 414, and clamping plate structure 415. The air passage 4131, which is axially connected, precisely guides the hot air to the air outlets arranged circumferentially and axially on the barrel wall. This allows the hot air to be introduced axially from the air outlet section 114 and then transmitted without damage along the inner cavity of the curling barrel 414 to the multiple air outlets on the barrel wall. This achieves a three-dimensional jet of hot air along the length and circumference of the hair strand, eliminating the "hot spots" and "cold spots" caused by traditional single-point air outlets and ensuring that the hair strands are heated evenly throughout the curling process. This significantly improves the consistency of perming, shortens the heating time per session, and reduces the risk of local overheating damage.

[0071] In this embodiment, the air passage structure 413 is independently disposed at the first end of the curling barrel 414, and the clamping plate structure 415 is integrated at the second end of the curling barrel 414 to form a flow channel system that is "closed at both ends, axially guided, and circumferentially vented". This ensures that the hot air path is completely confined to the inner cavity of the curling barrel 414, preventing heat energy from leaking to the outside. At the same time, the air outlets are arranged in an axial and circumferential array, which, together with the synchronous rotation of the rotating paddle 42, forms a dynamic hot air coverage field. This achieves efficient directional output of hot air energy and optimized spatial coverage, while reducing the heat load of the curling iron's overall heat conduction to the handle area. This improves thermal efficiency, reduces the overall temperature rise, and enhances safety and grip comfort.

[0072] like Figure 4 , Figure 5 , Figure 7 as well as Figure 8 As shown, the body 10 includes a first cylindrical body 13 and an air duct structure 14. One end of the first cylindrical body 13 is a mounting end for mounting the hair curling assembly 40; the peripheral wall of the first cylindrical body 13 has a second mounting opening. The first end of the air duct structure 14 extends through the second mounting opening to the outside of the first cylindrical body 13 and connects to the first cylindrical body 13, and the second end of the air duct structure 14 is located inside the mounting end. A mounting cavity 12 is formed between the outer surface of the air duct structure 14 and a portion of the inner surface of the first cylindrical body 13, an air inlet section 113 is formed between a portion of the inner surface of the air duct structure 14 and a portion of the inner surface of the first cylindrical body 13, and an air outlet section 114 is formed on the other portion of the inner surface of the air duct structure 14. In this way, the body 10 is designed as a modular layered structure consisting of a first cylinder 13 and an interpenetrating air duct structure 14, so that the air duct structure 14 is inserted laterally from the second mounting port on the peripheral wall of the first cylinder 13. Its outer wall and the inner wall of the first cylinder 13 enclose an independent mounting cavity 12 to accommodate the drive device 70, while its inner wall works together with the inner wall of the first cylinder 13 to construct a composite air duct structure of air inlet section 113 and air outlet section 114. This achieves the purpose of physical decoupling and space reuse of the power system (drive device 70) and hot air channel (air inlet section 113 / air outlet section 114) in a limited space, thereby significantly reducing the risk of heat conduction to the motor area and improving the overall structural compactness and manufacturing and assembly convenience.

[0073] In this embodiment, the air duct structure 14 penetrates the peripheral wall of the first cylinder 13. The interior of the air duct structure 14 is divided into an air inlet section 113 and an air outlet section 114, and its outer surface and the first cylinder 13 enclose a closed mounting cavity 12, so that the high-temperature hot air path is completely confined inside the air duct structure 14, while the drive device 70 is completely isolated in the "cold zone" mounting cavity formed by the outer wall of the air duct structure 14 and the cylinder wall of the first cylinder 13. This achieves three-dimensional spatial separation of heat flow and power flow, and achieves the dual optimization of thermal management and electrical safety without increasing the overall size of the machine. This results in a significant reduction in surface temperature rise, an extension of the drive device's lifespan, and an improvement in the overall fire resistance and anti-scalding performance of the machine.

[0074] like Figures 5 to 9 As shown, the air inlet section 113 includes a first sub-air inlet section 1131 and a second sub-air inlet section 1132 that are interconnected. The first sub-air inlet section 1131 is connected to the air outlet section 114 through the second sub-air inlet section 1132. The first cylinder 13 includes an annular surrounding plate 131 and a cylinder bottom 132 disposed within the annular surrounding plate 131. The cylinder bottom 132 is located at the mounting end. The air duct structure 14 includes a first sub-air duct structure 141, a second sub-air duct structure 142, and a third sub-air duct structure 143. The first sub-air duct structure 141 is located outside the first cylinder 13 and connected to the first cylinder 13. The inner surface of the first sub-air duct structure 141 forms the first sub-air inlet section 1131. The second sub-air duct structure 142 is located inside the first cylinder 13, and is disposed opposite to the cylinder bottom 132. A second sub-air inlet section 1132 is formed between the surface of the second sub-air duct structure 142 facing the cylinder bottom 132 and a portion of the inner surface of the cylinder bottom 132 and the first cylinder 13. A mounting cavity 12 is formed between the surface of the second sub-air duct structure 142 away from the cylinder bottom 132 and a portion of the inner surface of the first cylinder 13. A third sub-air duct structure 143 is disposed on the surface of the cylinder bottom 132 away from the mounting cavity 12, and an air outlet section 114 is formed on the inner surface of the third sub-air duct structure 143. The cylinder bottom 132 has a first through hole 1321, through which the second sub-air inlet section 1132 communicates with the air outlet section 114. In this way, the air inlet section 113 is a two-stage segmented airflow channel, so that the first sub-air inlet section 1131 receives the lateral hot air from the heating air device 20, and then achieves a 90° deflection and guidance within the first cylinder 13 via the second sub-air inlet section 1132. The air is then vertically introduced into the outlet section 114 formed by the third sub-air duct structure 143 through the first through hole 1321 at the bottom of the cylinder. This creates a non-linear, low-turbulence, and highly stable multi-stage airflow path, achieving efficient redirection of the hot air flow and smooth pressure transition within a limited axial space. Simultaneously, the above configuration minimizes the direct impact of hot air on the drive device 70 within the mounting cavity 12, thereby significantly reducing the heat radiation intensity of the motor, improving heat transfer efficiency, and enhancing system operational stability.

[0075] In this embodiment, a three-stage split combination of a first sub-air duct structure 141, a second sub-air duct structure 142, and a third sub-air duct structure 143 is adopted. Together with the first cylinder 13 and the bottom of the cylinder 132, an isolation structure is constructed. This allows the first sub-air duct structure 141 to handle the introduction of external hot air, the second sub-air duct structure 142 to enclose the air inlet / outlet section 113 and the mounting cavity 12 to form a thermal-electrical physical barrier, and the third sub-air duct structure 143 to achieve precise vertical output of hot air to the curling component 40. The three components form a triple isolation of "heat flow, airflow, and power flow" in space. This achieves the goal of complete physical isolation and functional zoning of the hot air channel and the drive device mounting cavity without increasing the overall size of the machine. This significantly improves the overall thermal management capability of the machine, reduces the surface temperature rise of the machine body, ensures the long-term reliable operation of the motor, and enhances the user's operational safety.

[0076] Optionally, the first sub-duct structure 141 is an annular structure, with the inner circumferential surface of the annular structure forming the first sub-inlet section 1131; and / or, the second sub-duct structure 142 is a first arc-shaped plate, with the first arc-shaped plate protruding towards the bottom 132 of the cylinder. In this way, designing the first sub-duct structure 141 as an annular structure, with its inner circumferential surface directly forming the flow channel wall of the first sub-inlet section 1131, allows hot air entering from the heating air device 20 to form a uniform, symmetrical, and low-disturbance annular inlet flow field along the inner wall of the annulus. This avoids vortices and pressure losses at the inlet due to structural asymmetry or abrupt edge changes, achieving a stable and efficient axial introduction effect for hot air entering the curling accessories from the initial stage. This significantly improves the airflow transmission efficiency of the inlet section 113, reduces the fan load, reduces noise, and enhances the pressure maintenance capability of the subsequent duct.

[0077] In this embodiment, the first sub-duct structure 141 is an annular structure, and the inner circumferential surface of the annular structure forms the first sub-inlet section 1131. The second sub-duct structure 142 is a first arc-shaped plate, which protrudes towards the bottom of the cylinder 132. Thus, designing the second sub-duct structure 142 as a first arc-shaped plate protruding towards the bottom of the cylinder 132 creates a gradually expanding slit channel between the arc-shaped plate and the bottom of the cylinder 132, serving as the second sub-inlet section 1132. The arc surface guides the airflow smoothly to a different direction, while its curved surface away from the bottom of the cylinder 132, together with the inner wall of the first cylinder 13, encloses a continuous, closed, and non-right-angle transition boundary of the mounting cavity. This achieves the goal of minimizing airflow impact, avoiding localized high-temperature stagnation areas, and providing a heat insulation barrier for the drive device while realizing a 90° hot air reversal guide. This results in improved airflow uniformity, reduced risk of localized heat accumulation, enhanced heat dissipation performance of the mounting cavity, and improved stability of the motor's operating environment.

[0078] like Figure 5 , Figure 7 , Figure 8 , Figure 14 as well as Figure 15 As shown, the third sub-duct structure 143 is a cylindrical structure, and the air passage 4131 is the second air passage hole. The air passage structure 413 includes a second cylindrical body 4132, an air passage plate 4133, and a connecting rod 4134. The air passage plate 4133 is disposed inside the second cylindrical body 4132, and the second air passage hole is disposed on the air passage plate 4133; the air passage plate 4133 contacts the cylindrical structure so that the air outlet section 114 communicates with the second air passage hole. The connecting rod 4134 is disposed on the air passage plate 4133 and avoids the second air passage hole. The connecting rod 4134 is connected to the clamping plate structure 415 and has an anti-rotation fit. In this way, by designing the air passage structure 413 as a modular transmission structure of "cylindrical air duct, detachable air passage plate, and anti-rotation connecting rod", the third sub-air duct structure 143 serves as a rigid hot air guide channel, and the air passage plate 4133 serves as a precisely positioned porous air outlet medium. The connecting rod 4134 and the clamping plate structure 415 achieve a rigid anti-rotation connection, so that the air passage plate 4133 and the curling iron 41 rotate synchronously without relative displacement. This achieves the goal of ensuring that the position of the air outlet is always dynamically aligned with the ventilation gap of the rotating paddle 42 while hot air is continuously output, forming a stable, leak-free, and offset "rotation-air outlet" collaborative channel. This significantly improves the hot air utilization rate, avoids airflow deviation and energy loss caused by structural loosening, and ensures that the hair is heated continuously and evenly during the curling process.

[0079] In this embodiment, a second air passage hole is opened on the air passage plate 4133 and it is sealed to the end face of the third sub-air duct structure 143. At the same time, the structural linkage and torque transmission are realized through the connecting rod 4134 in the non-air passage area, so that the hot air path flows into the inner cavity of the curling tube 414 from the third sub-air duct structure 143 only through the second air passage hole on the air passage plate 4133. The connecting rod 4134, as a non-flow channel component, independently undertakes the torque transmission and positioning functions, realizing the complete separation design of "air path" and "force path". This achieves the purpose of ensuring efficient and directional output of hot air while avoiding the transmission structure (connecting rod) from being deformed by heat or the heat conduction affecting the motor and gear system. This improves the thermal management isolation performance, extends the life of key transmission components, reduces the temperature rise of the whole machine, and enhances the long-term operational reliability of the system.

[0080] Optionally, the central axis of the connecting rod 4134 is coaxial with the central axis of the second cylinder 4132, and there are two second air passages that are spaced apart around the central axis of the connecting rod 4134. The central angle corresponding to each second air passage is greater than or equal to 110° and less than or equal to 130°. In this way, the connecting rod 4134 and the second cylinder 4132 are designed as a coaxial structure, and two symmetrically distributed fan-shaped second air passages with a central angle limited to the range of 110~130° are set on the air passage plate 4133. This allows hot air to enter from the third sub-air duct structure 143 and be evenly and symmetrically sprayed into the inner cavity of the curling tube 414 through the two large-angle second air passages, forming a ring-shaped hot air flow field with a wide coverage angle and a balanced air density. At the same time, it avoids the area where the connecting rod 4134 is located to achieve unobstructed airflow. This achieves the goal of maximizing the hot air outlet angle in a limited space and eliminating the "wind shadow zone" and "local overheating" phenomenon caused by traditional single-hole or narrow-angle air outlets. This significantly improves the heating uniformity of the curled hair, shortens the single perming time, and reduces the risk of hair damage caused by local high temperature.

[0081] In this embodiment, the central angle corresponding to each second air passage is 120°. By limiting the central angle of the two second air passages to 120° and symmetrically arranging them around the coaxial connecting rod 4134, the hot air jet fan area can ensure that it fully covers the ventilation gap of the rotating blade 42, while reserving a "non-perforated area" with sufficient structural strength to maintain the mechanical rigidity and thermal stability of the air passage plate 4133. At the same time, it avoids structural fatigue fracture or thermal deformation warping caused by excessively large apertures, achieving the goal of optimal balance between airflow efficiency and structural reliability. This improves the heat resistance life of the air passage plate, prevents deformation or cracking caused by thermal stress concentration, and ensures the stability of air outlet under long-term high-frequency rotation.

[0082] In this embodiment, the cylindrical structure includes a second arc-shaped plate 1431 and a third arc-shaped plate 1432 that are interconnected and arranged opposite to each other, with the protrusion directions of the second arc-shaped plate 1431 and the third arc-shaped plate 1432 being consistent. The orthographic projection of the second air passage hole onto the cylindrical structure is located within the cylindrical structure. Thus, the third sub-duct structure is designed as a non-fully closed annular shell formed by splicing two opposing arc-shaped plates with consistent protrusion directions. This allows the two arc-shaped plates to form an "open ring" airflow channel in the axial direction, ensuring stable circumferential flow of hot air within the cylindrical structure while reserving space for assembly and maintenance. Simultaneously, it ensures that the orthographic projection of the second air passage hole onto the outer surface of the cylindrical structure falls entirely within the solid projection area enclosed by the two arc-shaped plates, preventing the hole opening from being exposed to structural gaps. This achieves efficient directional output of hot air while preventing leakage from structural seams and preventing high-temperature airflow from directly impacting the sidewalls of the mounting cavity or transmission components, thereby significantly improving hot air utilization efficiency, reducing heat conduction risks, and enhancing the overall sealing and safety of the machine.

[0083] Specifically, a cylindrical structure is constructed using two convex arc-shaped plates protruding in the same direction. The projection position of the second air passage is strictly limited to the inner solid area covered by the two arc-shaped plates. This ensures that the airflow path of the air outlet is completely "enclosed" within the flow channel, forming a closed-loop airflow mechanism where "the hole is inside the wall and the air is in the cavity." This avoids turbulence, eddies, or lateral dissipation of airflow at the outlet due to excessive spacing between the arc-shaped plates or hole misalignment. This achieves the goal of "zero leakage, zero offset, and low disturbance" precise transmission of hot air from the cylindrical structure to the curling components. Consequently, it significantly improves the stability of the airflow direction, enhances the consistency of the curling style, and reduces the increase in energy consumption and the extension of the perming time caused by airflow dissipation.

[0084] like Figure 4 and Figure 16 As shown, the hair curling accessory also includes a transmission assembly and a bearing structure 80, with the bearing structure 80 housed within the body 10. The rotating paddle 42 includes a rotating base 422 and a paddle 423. The drive unit 70 is drivenly connected to the rotating base 422 via the transmission assembly; the rotating base 422 is connected to the inner ring of the bearing structure 80. The paddle 423 is mounted on the rotating base 422 to rotate synchronously with it. In this way, the rotating paddle 42 is decomposed into a modular structure of independent rotating base 422 and paddle 423. The bearing structure 80 realizes low-friction rotational support between the rotating base 422 and the body 10. At the same time, the rotating base 422 is centrally driven by the transmission component, so that the paddle 423 only acts as a force output component and follows the movement. This allows the driving load to be directly transmitted from the transmission component to the rotating base 422, and then efficiently transmitted to the body 10 through the bearing structure 80. This achieves physical decoupling between the power input path and the hair winding disturbance path, and achieves the purpose of significantly reducing the rotational inertia of the rotating component and the reaction impact of the radial load on the transmission system. This improves the motor drive response accuracy, reduces transmission gear wear, extends the service life of the transmission component, and ensures a smooth and vibration-free hair curling process.

[0085] In this embodiment, the bearing structure 80 serves as the supporting reference for the rotating system, and the rotating seat 422 serves as the rotating core unit that bears the transmission torque and the load of the paddle 423. The paddle 423 rotates synchronously with the rotating seat 422 through a mechanical connection, so that the bearing structure 80 bears all radial and axial loads. The rotating seat 422 serves as a torque transmission relay, and the paddle 423 serves as a non-load-bearing "functional actuator". This achieves the dual protection of thermal isolation and force isolation between the drive system and the hair contact parts under high temperature, high humidity, and frequent rotation conditions. This results in significantly reducing the operating temperature of the bearing and transmission system, preventing structural jamming caused by hair entanglement or thermal deformation, and improving the operational reliability and safety of the whole machine in long-term use.

[0086] like Figure 5 , Figures 7 to 10 As shown, the bottom 132 of the cylinder also has a second through hole 1322, which avoids the third sub-air duct structure 143; the drive device 70 is a motor, and the transmission components include a gear structure 90 and an internal gear ring structure 424. The gear structure 90 passes through the second through hole 1322, and the motor shaft of the motor is drivenly connected to the gear structure 90. The internal gear ring structure 424 is mounted on the rotating seat 422 and meshes with the gear structure 90. The motor shaft of the motor is eccentrically positioned relative to the central axis of the rotating seat. In this way, the motor shaft is eccentrically arranged relative to the central axis of the rotating seat 422. The gear structure 90 and the internal gear ring structure 424, which are inserted through the second through hole 1322 in the bottom of the cylinder 132, form a planetary gear transmission system. This allows the motor to drive the internal gear ring structure 424 to rotate in an eccentric drive manner without occupying the central space of the rotating seat 422. This enables the rotating paddle 42 to revolve around its own central axis. At the same time, the third sub-air duct structure 143 is centrally arranged due to the avoidance of the second through hole 1322 and is not interfered with by the transmission components. This achieves the goal of achieving spatial decoupling of "power input, transmission, and rotation output" and compact integration design in a limited axial space, so that heat flow and force flow do not interfere with each other. This significantly improves the utilization rate of the internal space of the machine, ensures the integrity and continuity of the hot air channel, avoids interference between the motor or gear and the air outlet structure, and reduces the radial dimension of the whole machine.

[0087] In this embodiment, an eccentric motor shaft drives a gear structure 90, which meshes with an internal gear ring structure 424 fixed on a rotating seat 422. This achieves an "external meshing planetary reduction" structure that drives a rotating paddle 42, converting the eccentric motion of the motor shaft into a stable rotation of the internal gear ring structure 424 around its central axis. The gear ratio is used to achieve low-speed, high-torque output, and the radial inertial force caused by eccentricity is automatically offset during transmission. This achieves the goal of high torque, low speed, and high stability rotational drive without the need for additional reduction mechanisms or complex linkages, thereby significantly reducing motor power requirements, reducing transmission noise, improving rotational smoothness, and extending the life of gears and bearings.

[0088] like Figure 5 and Figure 8As shown, the third arc-shaped plate 1432 is arranged around the second arc-shaped plate 1431. The outer plate surface of the second arc-shaped plate 1431 is provided with a first connecting plate 1433. The first plate surface of the first connecting plate 1433 facing the bottom of the cylinder 132 has a first distance from the bottom of the cylinder 132. The second plate surface of the first connecting plate 1433 away from the bottom of the cylinder 132 has a second distance from the end face of the cylindrical structure away from the bottom of the cylinder 132. The body 10 and the air passage structure 413 are connected by fasteners passing through the first connecting plate 1433 and the air passage structure 413. In this way, the third arc-shaped plate 1432 surrounds the second arc-shaped plate 1431 to form the main body of the cylindrical air duct, and the first connecting plate 1433 extends to the outside of the second arc-shaped plate 1431. The first connecting plate 1433 is set to maintain a first distance between itself and the bottom of the cylinder 132 and a second distance between itself and the end face of the cylindrical structure, forming a "suspended connection interface". By allowing the fasteners to pass through the mating part of the first connecting plate 1433 and the air passage structure 413, the axial locking between the body 10 and the air passage structure 413 is achieved, thus avoiding the fasteners from directly penetrating the hot air channel or interfering with the airflow path. At the same time, the "double gap design" provides buffer space for thermal expansion, assembly tolerance and vibration displacement, achieving the purpose of a composite assembly relationship of "rigid connection, flexible buffer, thermal isolation and no interference" between the body and the high-temperature air passage structure. This significantly improves the assembly accuracy, prevents structural jamming or sealing failure caused by thermal deformation, and ensures the long-term airtightness and structural integrity of the hot air channel.

[0089] In this embodiment, the first connecting plate 1433 serves as a "non-contact connection bridge" between the body 10 and the air passage structure 413. By precisely controlling the two axial distances (the first distance and the second distance) between it and the bottom of the cylinder 132 and the end face of the cylindrical structure, an elastic pre-tightening space is formed. The fasteners transmit the axial pre-tightening force, while the heat conduction path is naturally blocked by the "air gap". At the same time, the air passage structure 413 can move slightly axially when it is heated and is not constrained by the rigidity of the body. This achieves the dual independent design purpose of realizing the functions of "mechanical connection" and "thermal isolation", thereby significantly reducing the heat load of heat conduction to the body and drive components, extending the service life of the motor and bearings, and improving the overall safety and long-term operational reliability of the machine.

[0090] like Figure 5 and Figure 14As shown, a mating recess is formed between the second plate surface of the first connecting plate 1433 and the second arc-shaped plate 1431. A mating protrusion 4135 is provided on the air passage plate 4133, which extends into the mating recess for limiting engagement with it. Thus, a mating recess is designed in the joint area of ​​the first connecting plate 1433 and the second arc-shaped plate 1431, and a corresponding mating protrusion 4135 matching its shape is provided on the air passage plate 4133. This creates a "concave-convex fitting limiting structure" during axial assembly, ensuring that the air passage structure 413 is not only axially pressed by fasteners during installation but also achieves circumferential positioning and anti-rotation constraint through radial embedding of the geometric surface. Simultaneously, it eliminates relative rotation caused by thermal expansion and contraction or vibration, achieving high-precision, zero-gap, and torsional-resistant stable alignment between the air passage structure and the machine's air duct. This significantly improves the coaxiality of the hot air passage and prevents airflow deviation, eddy current loss, or localized high-temperature accumulation caused by misalignment.

[0091] In this embodiment, the mating recess and mating protrusion 4135 constitute a pure geometric limiting structure, realizing multi-degree-of-freedom self-alignment and anti-torsional fixation between the air duct 4133 and the air duct of the machine body. By embedding the mating protrusion 4135 into the mating recess to form a "mechanical locking" relationship, not only is the circumferential rotation of the air duct 4133 restricted, but its axial micro-movement and radial sway are also constrained simultaneously, forming a "three-in-one" stable support mechanism. This achieves the goal of structural reliability under high-temperature conditions without adding extra fasteners, without damaging the integrity of the hot air duct, and without introducing metal friction and wear. This significantly reduces assembly complexity, eliminates abnormal noise and airflow fluctuations caused by loosening, extends the service life of the air duct structure, and improves the user experience.

[0092] Optionally, the connector 30 is equipped with a magnetic structure for magnetically engaging with the heating air device 20. This integrated magnetic structure on the connector 30 allows for a quick, precise, and tool-free connection between the hair curling accessory and the heating air device 20 via magnetic attraction. The magnetic force enables automatic axial alignment and stable radial engagement, eliminating the need for traditional clips, threads, or plug-in mechanical locking structures. This achieves a seamless, quick-release connection between the hair curling accessory and the heating air device 20, significantly improving user efficiency, reducing operational complexity, and enhancing ease of use and user experience.

[0093] In this embodiment, the magnetic structure serves as a non-contact physical coupling medium between the connector 30 and the heating air device 20, enabling synchronous automatic alignment and sealing pre-pressurization of the electric heating interface and the airflow channel. Positioning and pressing are completed by magnetic force without mechanical stress, allowing the hot air outlet and the air inlet 111 of the hair curling accessory to achieve high-precision coaxial fit. At the same time, the magnetic surface itself has a certain elastic compensation capability, which can adapt to minor assembly deviations. This achieves the goal of integrated docking of airtight connection, electrical contact (such as power supply contacts), and mechanical positioning, thereby significantly improving the efficiency of hot air transmission, preventing air leakage and energy consumption, ensuring power supply stability, and extending the life of the interface.

[0094] Optionally, the drive unit 70 is a motor, and the hair curling accessory also includes an operating device 110. The operating device 110 is connected to the motor to control the motor's direction of rotation through rotation, pressing, sliding, or touch operation. In this way, integrating a multi-functional operating device 110 into the hair curling accessory allows direct control of the motor's direction of rotation via different interactive methods such as rotation, pressing, sliding, or touch. This enables users to switch rotation directions in real time without stopping or changing hand positions during the curling process, achieving the goal of constructing a closed-loop human-machine interaction system integrating "operation, feedback, and control." This results in significantly improved curling efficiency, reduced operator fatigue, enhanced styling accuracy, and improved safety.

[0095] In this embodiment, a single operating device 110 is compatible with multiple input methods (rotation, pressing, sliding, touch), and the motor direction is switched by dynamically responding to different gesture commands through signal recognition logic. By achieving multimodal input fusion control within a limited space, multiple physical buttons or external remote controls are avoided. At the same time, haptic feedback or no feedback design is used to adapt to different user habits, achieving the goal of a natural and intuitive control experience of "gesture as command". This results in significantly improving the product's technological feel, reducing the error rate, supporting personalized operation preference settings, and enhancing the product's differentiated competitiveness.

[0096] It should be noted that the operating device 110 is compatible with multimodal input methods. Rotation (continuous adjustment), pressing (instant switching), sliding (gradual control), and touch (intelligent recognition) can be freely combined to cover different usage scenarios.

[0097] like Figures 1 to 4 , Figure 17 and Figure 18As shown, the curling accessory also includes a heat insulation component 50. The heat insulation component 50 includes an inner heat insulation cover 51 and an outer heat insulation cover 52. The inner heat insulation cover 51 covers the body 10 and the curling component 40, and the outer heat insulation cover 52 is fitted over at least a portion of the inner heat insulation cover 51. Thus, a double-layer vacuum / air insulation structure composed of the inner heat insulation cover 51 and the outer heat insulation cover 52 is provided outside the body 10 and the curling component 40. This allows the inner heat insulation cover 51 to closely adhere to the high-temperature components (body 10 and curling component 40), forming the first thermal barrier. A closed air layer or low thermal conductivity gap is formed between the outer heat insulation cover 52 and the inner heat insulation cover 51, utilizing the low thermal conductivity of air to achieve secondary thermal insulation. This achieves a highly efficient thermal management mechanism that combines "close-fitting heat resistance + spatial heat insulation" for two-level synergistic defense, thereby significantly reducing the surface temperature of the outer casing, preventing user burns, improving handheld comfort, and extending the service life of internal electronic components (such as motors and circuits).

[0098] like Figure 18 As shown, the heat insulation cover 52 has a second side notch 521 for allowing hair to enter. The position of the second side notch 521 is adjustable to adjust the direction of hair entry. In this way, the user can manually adjust the position of the second side notch 521 according to the direction of hair parting or curling habits, achieving the purpose of adapting to different user operating habits and hairstyle design needs, thereby realizing the technical effect of flexibly adjusting the entry angle and curling trajectory without changing accessories.

[0099] like Figure 17 and Figure 18 As shown, the hair curling accessory also includes a mating component 60 located between the heat-insulating inner cover 51 and the heat-insulating outer cover 52. The heat-insulating outer cover 52 is locked or unlocked with the heat-insulating inner cover 51 through the mating component 60. In this way, when it is necessary to lock or unlock the heat-insulating inner cover 51 and the heat-insulating outer cover 52, the user only needs to operate the mating component 60, thereby realizing the tool-free and quick unlocking of the heat-insulating component 50. This achieves the dual purpose of convenient disassembly and assembly and position locking of the heat-insulating outer cover 52 without compromising the overall structural sealing and heat insulation performance.

[0100] like Figure 17 and Figure 18As shown, the mating assembly 60 includes a first mating portion 61 and a second mating portion 62. The first mating portion 61 is disposed on the outer heat insulation cover 52, and the second mating portion 62 is disposed on the inner heat insulation cover 51. One of the first mating portion 61 and the second mating portion 62 is a protrusion, and the other is a recess. The protrusion extends into the recess and can slide along the extending direction of the recess, thereby locking or unlocking the outer heat insulation cover 52 and the inner heat insulation cover 51. Thus, by providing a sliding engagement assembly 60 composed of a protrusion and a recess between the outer heat insulation cover 52 and the inner heat insulation cover 51, the protrusion can mechanically limit the movement of the outer heat insulation cover 52 and the inner heat insulation cover 51 along the extending direction of the recess, achieving the purpose of secure locking and quick unlocking of the outer heat insulation cover 52 relative to the inner heat insulation cover 51 without the need for screws, clips, or tools.

[0101] In this embodiment, the convex and concave parts cooperate to form a three-stage mechanical action of "sliding in, locking, and exiting", so that the heat insulation cover 52 has dual mechanical constraints of anti-torsion and anti-axial dislodgement in the locked state. This achieves the purpose of maintaining structural stability, preventing loosening, and preventing misoperation in high temperature and high humidity working environment. Thus, the heat insulation cover 52 does not shift, loosen, or fall off under continuous hot air impact and frequent operation conditions.

[0102] Optionally, there is one first mating part 61 and one second mating part 62; or, there is one first mating part 61 and multiple second mating parts 62, and the first mating part 61 may selectively engage with at least one second mating part 62; or, there are multiple first mating parts 61, which are spaced apart along the axial direction or circumferential direction of the heat insulation cover 52; and there are multiple second mating parts 62, which are correspondingly arranged with multiple first mating parts 61, and each second mating part 62 engages with at least one first mating part 61. In this way, an optional single-convex-multiple-concave or multi-convex-multiple-concave combination fitting component 60 is provided between the heat insulation outer cover 52 and the heat insulation inner cover 51, allowing one convex part to selectively limit the fit with multiple concave parts distributed along the circumference, or multiple convex parts to form a multi-point collaborative locking with multiple concave parts. This achieves the purpose of supporting the heat insulation outer cover 52 to achieve precise and stable positioning at multiple preset angles or axial positions without adding additional structures. This enables users to freely switch the hair entry direction and locking position according to the hair strand direction, curling arc or operating habits.

[0103] In this embodiment, there are two second mating parts 62, which are correspondingly arranged with the two first mating parts 61. Each second mating part 62 is limited to one of the first mating parts 61. In this way, through the modular configuration relationship between the first mating parts 61 and the second mating parts 62, the heat insulation component 50 achieves axial and circumferential dual locking through a "multi-convex-multi-concave" mating method.

[0104] like Figure 17 and Figure 18 As shown, the recess includes a guide groove 621 and a mating groove 622. The guide groove 621 extends along the central axis of the heat insulation assembly 50 to guide the protrusion; the mating groove 622 communicates with the guide groove 621 and extends along the axial direction of the curling assembly 40 to limit the engagement with the protrusion. When it is necessary to lock the heat insulation outer cover 52 and the heat insulation inner cover 51, the operating protrusion slides sequentially along the guide groove 621 and the mating groove 622 until the protrusion moves to the point of being limited by the mating groove 622; when it is necessary to unlock the heat insulation outer cover 52 and the heat insulation inner cover 51, the operating protrusion slides sequentially along the mating groove 622 and the guide groove 621 until the protrusion moves to the point of disengaging from the guide groove 621. In this way, an L-shaped or T-shaped composite sliding recess structure is formed by an axially extending guide groove 621 and a mating groove 622 extending axially along the curling iron on the heat insulation inner cover 51. This allows the protrusion on the heat insulation outer cover 52 to first slide axially along the guide groove 621 to a predetermined position, and then rotate into the mating groove 622 to achieve circumferential limiting and locking. When unlocking, the reverse operation causes the protrusion to retract along the mating groove 622 and then disengage along the guide groove 621. This achieves the integration of three functions—axial positioning, circumferential locking, and anti-misoperation—between the heat insulation outer cover 52 and the heat insulation inner cover 51—without bolts or buckles.

[0105] In this embodiment, by designing the guide groove 621 and the mating groove 622 as an asymmetrical path structure that is perpendicularly connected to each other, it is ensured that the protrusion completes the locking and unlocking in the order of "axial sliding in, circumferential rotation and axial limiting" and "circumferential retraction and axial pulling out", so as to prevent the heat insulation cover 52 from being accidentally loosened due to thermal expansion, vibration or accidental contact, thereby achieving the mechanical safety locking technology effect of unidirectional controllability, anti-reverse release and operation perception.

[0106] In this embodiment, there are two first mating parts 61, which are spaced apart along the axial direction of the heat insulation cover 52. There are also two second mating parts 62, which are correspondingly arranged with the two first mating parts 61. The guide grooves 621 of the two second mating parts 62 are evenly distributed around the central axis of the heat insulation component 50. Each first mating part 61 can selectively engage with any one of the second mating parts 62 to adjust the position of the second side notch 521. In this way, two first mating parts 61 (protrusions) are provided on the heat insulation outer cover 52 at intervals along the axial direction, and two second mating parts 62 (recesses) are provided on the heat insulation inner cover 51 at equal intervals along the circumference. Each protrusion can be independently locked with the guide groove 621 and mating groove 622 of any one of the recesses. Thus, through the combination structure of dual-point axial cooperative limiting and circumferential multi-position selectable matching, the purpose of dual control of axial stability and anti-movement of the heat insulation outer cover 52 and free adjustment of circumferential angle is achieved in the locked state. Users can steplessly switch the circumferential starting position of the hair inlet (first side notch) according to the direction of hair parting, curly hair arc or left and right hand operation habits without replacing parts or reassembling.

[0107] Specifically, the two protrusions constrain the heat insulation cover 52 at two different height positions in the axial direction. At the same time, each protrusion can be independently limited with the concave part at different circumferential positions. This achieves the technical goal of locking the hair inlet at any angle within the circumferential range of 0° to 180° while maintaining the overall rigidity and torsional strength of the heat insulation cover 52. This enables a high degree of freedom in operation, allowing for real-time switching between left-hand, right-hand, middle-part, and side-part hairstyles during the curling process.

[0108] In this embodiment, a composite structure is formed by using the inner heat insulation cover 51 as a rigid heat-conducting blocking layer and the outer heat insulation cover 52 as a flexible deformation buffer layer to form a "rigid and flexible" thermal protection system. By having the inner heat insulation cover 51 (such as ceramic fiber or high-temperature resistant silicone layer) directly shield radiative and conductive heat, while the outer heat insulation cover 52 (such as silicone or aerogel foam) not only further blocks convective heat, but also absorbs vibration, buffers drop impact, and conforms to the hand shape to improve grip. This achieves the goal of integrating the three functions of "thermal protection - structural protection - human-machine adaptation", thereby significantly improving the product safety level, enhancing impact resistance reliability, optimizing human-machine engineering experience, and supporting multiple appearance designs (such as skin-like feel, soft-touch coating).

[0109] like Figure 17As shown, the heat-insulating inner cover 51 includes a first cover body 511 and a second cover body 513. The first cover body 511 covers the hair curling assembly 40 and has a third side notch 512 for hair to enter. The orthographic projection of the second side notch 521 onto the third side notch 512 is located within the third side notch 512. A second mating part 62 is disposed on the first cover body 511. The second cover body 513 is connected to the first cover body 511 and covers the body 10. A stepped surface 514 is formed at the connection between the first cover body 511 and the second cover body 513, and the stepped surface 514 is used to limit and stop the heat-insulating outer cover 52. In this way, by dividing the heat insulation inner cover 51 into a first cover body 511 and a second cover body 513 and forming a stepped surface 514 at the connection between the two, the second mating part 62 (recess) is concentrated on the first cover body 511 that only wraps the hair curling component 40. This allows the locking mechanism of the mating component 60 to act only on the local structure near the high temperature area, while the second cover body 513 only undertakes the functions of heat insulation and installation support. This achieves the purpose of functional zoning and heat load isolation of the heat insulation structure, reduces the overall heat conduction of the heat insulation inner cover 51, avoids the mating component from failing due to high temperature aging, and extends the service life of the locking mechanism.

[0110] In this embodiment, the heat insulation cover 52 is rigidly positioned by its end face and the stepped surface 514 during installation. At the same time, it ensures that the orthographic projection of the second side notch 521 on the third side notch 512 is completely inside it. This achieves the purpose of precise axial positioning and circumferential alignment of the heat insulation cover without additional fasteners. This ensures that the hair inlet channel (the first side notch and the second side notch) always coincides and avoids misalignment that could cause hair to get stuck or be exposed and burned.

[0111] In this embodiment, the first mating part 61 is a convex part, and there are two convex parts, which are spaced apart along the axial direction of the heat insulation cover 52; the second mating part 62 is a concave part, and there are two concave parts, with the guide grooves 621 of the two concave parts spaced apart along the circumferential direction of the curling iron 41, and the mating grooves 622 of the two concave parts spaced apart along the axial direction of the curling iron 41.

[0112] like Figure 19 and Figure 20 As shown, this application also provides a hair curler, including a heating air device 20 and a hair curling accessory 100. The connecting seat 30 of the hair curling accessory 100 is detachably connected to the heating air device 20, and the hot air outlet of the heating air device 20 is connected to the air inlet 111 of the hair curling accessory 100. The hair curling accessory 100 is the aforementioned hair curling accessory.

[0113] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0114] By independently housing the drive unit within a mounting cavity completely isolated from the airflow channel, the hot air flow path (airflow channel) is physically separated from the working area of ​​the drive unit. Furthermore, the airflow channel employs a non-linear layout to block heat conduction paths, effectively isolating the drive unit from direct heat radiation and convection heating by high-temperature hot air. This significantly reduces the operating temperature of the drive unit, extends its service life, and improves operational safety. It also solves the problem in existing technologies where the motor driving the curling iron or rotating paddle is located within the hot airflow channel, affecting its service life and posing safety hazards. Simultaneously, the curling accessories utilize an independent, enclosed mounting cavity within the body, coupled with a non-linear airflow channel design. This ensures that high-temperature airflow flows from the air inlet through a reversible non-linear channel to the air outlet of the curling components. The drive unit remains within a sealed cavity free from hot air interference throughout, achieving zero intersection and zero thermal coupling between the hot air path and the power system path. This ensures that while maintaining efficient curling and drying functions, the performance degradation of the drive unit due to high-temperature aging, insulation deterioration, or torque attenuation is completely avoided.
