Description

Technical Field

[0001] This utility model relates to the field of hair styling device technology, and in particular to an automatic hair curling iron hair winding structure. Background Technology

[0002] Automatic curling irons are increasingly popular with consumers due to their ease of use and ability to achieve various curling effects. These devices typically include a curling section, the core of which is an outer barrel containing a curling chamber for holding the hair. Vertical curling levers are located within the curling chamber. These levers are usually driven by a mechanism and rotate within the curling chamber. When hair is introduced into the curling chamber and comes into contact with the rotating levers, the levers, through their rotational motion, wrap the hair around themselves or between each other, and combined with the heat from the heating element, thus achieving curling and setting of the hair.

[0003] Most automatic curling irons on the market typically have two curling levers inside the curling chamber. This presents several limitations in actual use. For example, the hair may not be evenly distributed during curling, resulting in curls that are not always tight, voluminous, or neat. Fewer wrapping points mean that each curl may not be fully engaged, leading to longer overall time and lower efficiency. Furthermore, when dealing with coarse or long hair, they may not provide sufficient and balanced grip and combing force, resulting in some hair not being effectively curled or curling insufficiently, affecting the final style's durability and consistency.

[0004] Therefore, those skilled in the art have been seeking to improve the structure of the curling section of automatic curling irons, especially to optimize the setting of the curling lever, in order to significantly improve the curling effect while ensuring the reliability and ease of use of the device. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic curling iron with a hair-winding structure that has the characteristics of good curling effect and uniform curling.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] An automatic curling iron hair-winding structure includes a handle portion and a curling portion disposed on the handle portion. The curling portion includes an outer cylinder, and the outer cylinder includes side shells symmetrically disposed on the left and right sides. A symmetrical side slot is formed between the side shells.

[0008] The outer cylinder has a hair-curling cavity inside, and a hair-clamping component is provided inside the hair-curling cavity. The hair-clamping component has a hair-clamping groove along the front-to-back direction. The hair-curling cavity also has four vertical hair-curling levers. The hair-curling levers are arranged in a circumferential direction and can rotate inside the hair-curling cavity. There are gaps between the hair-curling levers. When the hair-curling levers are not rotated, the side slots, gaps, and hair-clamping grooves are aligned in the front-to-back direction.

[0009] The curling section also includes a curling post with heating function that is vertically arranged in the middle, and the hair clamping component is arranged on the upper end of the curling post; the curling lever is arranged on the periphery of the curling post.

[0010] The two sides of the curling iron are symmetrical and each forms a first arc surface, and a second arc surface is formed on one side facing the center of the circumference between the first arc surfaces.

[0011] The bottom of the curling iron is provided with a rotating base connected to the motor, and the curling iron is evenly arranged along the circumference of the rotating base.

[0012] The hair clipping assembly includes two side flaps, the hair clipping groove is formed between the two side flaps, and the side flaps are also provided with friction protrusions.

[0013] Each side housing has an air blower facing the curling cavity on its inner wall, and the air blowers in the two side housings are arranged opposite each other.

[0014] The air outlet is elongated in the vertical direction of the side shell, and guide strips are evenly distributed on the air outlet.

[0015] An infrared light strip is provided on the inner side of the side housing, and there are two air outlets on the inner side of one side of the side housing, which are respectively located on both sides of the infrared light strip.

[0016] The side slot has symmetrical first curved portions on both sides, and the lower end of the first curved portions is connected to a second curved portion. The distance between the first curved portions on both sides of the side slot is less than the distance between the second curved portions on both sides of the side slot.

[0017] The upper ends of both sides of the side slot form an arc-shaped transition section.

[0018] The beneficial effects of this utility model are:

[0019] By incorporating four evenly distributed curling rods within the curling chamber, more winding and support points are created compared to the traditional double-rod design. The number and placement of the curling rods are rationally arranged, ensuring the hair is evenly grasped and dispersed during rotation, effectively preventing localized accumulation and resulting in more balanced force on the hair strands during curling. This ensures smooth hair winding, significantly optimizing the tightness, volume, and regularity of the final curls, meeting diverse styling needs. Furthermore, the side slots, spacing sections, and hair clamping slots are aligned front-to-back, making it easier for the hair strands to enter the curling chamber after being clamped, increasing operational convenience. Additionally, the first and second curved surfaces of the curling rods reduce frictional resistance between the hair and the rods, further ensuring smooth hair winding. Attached Figure Description

[0027] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0028] Reference Figure 1 , Figure 2 This utility model proposes an automatic hair curling iron hair winding structure, including a handle part 1, a hair curling part 2 disposed on the handle part 1, the hair curling part 2 including an outer cylinder 3, the outer cylinder 3 including side shells 30 symmetrically disposed on the left and right sides, and a symmetrically arranged side slot 32 formed between the side shells 30.

[0029] The outer cylinder 3 has a hair-curling cavity 33 inside, and a hair-clamping component 6 is provided inside the hair-curling cavity 33. The hair-clamping component 6 has a hair-clamping groove 61 formed along the front-to-back direction. Four vertical hair-curling levers 5 are also provided inside the hair-curling cavity 33. The hair-curling levers 5 are arranged in a circumferential direction and can rotate inside the hair-curling cavity 33. Spacing portions 50 are formed between the hair-curling levers 5. (Refer to...) Figure 3 When the hair curling lever 5 is not rotated, the side slot 32, the spacer 50, and the hair clip slot 61 are aligned in the front-to-back direction.

[0030] The curling section 2 also includes a curling post 4 with a heating function that is vertically arranged in the middle, and a hair clamping component 6 is arranged on the upper end of the curling post 4; the curling lever 5 is arranged on the periphery of the curling post 4.

[0031] Reference Figure 4 The two sides of the curling iron 5 are symmetrical and form a first arc surface 51 respectively. The side facing the center of the circumference between the first arc surfaces 51 forms a second arc surface 52.

[0032] Specifically, by setting four evenly distributed curling rods 5 along the circumference within the curling chamber 33, more winding and support points are formed compared to the traditional double-rod design. The number and position of the curling rods 5 are reasonably set, and the hair is evenly grasped and dispersed by the four rods during rotation, effectively avoiding local accumulation and making the hair strands more evenly stressed when curling. This ensures smooth winding of the hair, and the final curl's tightness, volume, and regularity are significantly optimized, meeting diverse styling needs.

[0033] Meanwhile, the side slots 32, the spacers 50, and the hair clamping slots 61 are aligned in the front-to-back direction, making it easier for the hair strands to enter the curling chamber 33 after being clamped by the hair clamping slots 61, thus increasing the convenience of operation. Compared to the traditional two-lever design, the four curling levers 5 can form more spacers 50 on the circumference, which also makes it more likely that the spacers 50 are aligned with the side slots 32 and the hair clamping slots 61 in the front-to-back direction, resulting in higher reset efficiency and further increasing operational efficiency.

[0034] Furthermore, the design of the first arc surface 51 and the second arc surface 52 of the curling iron 5 can reduce the frictional resistance between the hair and the curling iron 5, reduce damage to the hair strands, and further ensure that the hair is smoothly wrapped.

[0035] The bottom of the curling iron 5 is equipped with a rotating base 53 connected to a motor, and the curling iron 5 is evenly arranged along the circumference of the rotating base 53. The curling iron 5 and the rotating base 53 are integrally formed to ensure that the curling iron 5 rotates synchronously and stably, applying a continuous and uniform curling force to the hair strands, solving the problem of insufficient curling force in traditional designs and improving the durability of the style.

[0036] Reference Figure 2 , Figure 5The hair clip assembly 6 includes two side flaps 60, a hair clip groove 61 is formed between the two side flaps 60, and friction protrusions 62 are also provided on the side flaps 60.

[0037] Specifically, during the curling process, the hair clip component 6 is used to fix the upper end of the hair bundle, the lower end of the hair bundle is placed into the curling cavity 33, the curling iron is turned on, the curling post 4 heats up, the blower nozzle 31 blows air, and the curling lever 5 rotates to wrap and curl the hair bundle. The hair clip groove 61 can serve to fix the upper end of the hair bundle.

[0038] Reference Figure 5 Each side housing 30 has an air blower 31 facing the hair curling cavity 33 on its inner wall, and the air blowers 31 in the two side housings 30 are arranged opposite each other.

[0039] The air outlet 31 is elongated along the vertical direction of the side housing 30, and guide strips 310 are evenly arranged on the air outlet 31.

[0040] Specifically, the blower nozzle 31 actively delivers hot air into the curling chamber 33. Combined with the heat-generating curling posts 4 and the reasonably distributed curling levers 5 within the curling chamber 33, on the one hand, convection heating that penetrates the hair strands can be formed within the curling chamber 33. The hot air generated by the blower nozzle 31 within the curling chamber 33 can fully act on the inner and outer layers of the hair, resulting in higher heating efficiency, significantly improved heat transfer efficiency, and shorter styling waiting time. On the other hand, the blower nozzle 31 can also actively deliver cold air into the curling chamber 33. After the hair strands enter the curling chamber 33, they are first heated and softened by the curling posts 4, making them easier to shape. Then, the blower nozzle 31 blows cold air to quickly cool and set the style, enhancing the hairstyle's durability. This alternating hot and cold design not only significantly improves the hair styling effect but also effectively reduces the damage to the hair caused by high temperatures, taking into account both aesthetics and hair care needs.

[0041] Furthermore, the air outlet 31 is elongated along the vertical direction of the side housing, covering the vertically positioned curling iron 5, to achieve full vertical airflow coverage and ensure uniform heating of the hair strands. The air guide strip 310 divides the airflow into multiple directional fine streams, enhancing the airflow's ability to penetrate thick hair strands and improving heat utilization.

[0042] Reference Figure 6 In one implementation, an infrared lamp strip 34 is provided on the inner side of the side housing 30, and two air outlets 31 are located on the inner side of one side of the side housing 30, respectively located on both sides of the infrared lamp strip 34. Integrating the infrared lamps into the inner wall of the side housing 30 and distributing them side by side with the elongated air outlets 31 ensures that the phototherapy coverage area and the hot air action area highly overlap, achieving synchronous and uniform photothermal action without the need for additional operation steps, thus improving the user experience.

[0043] Specifically, on the one hand, infrared light irradiation pre-softens the hair strands, making subsequent hot air heating more even and efficient, reducing the required heating temperature and fundamentally mitigating heat damage. For hair damaged by dyeing and perming, a combination of red and near-infrared light irradiation can be used to neutralize chemical residues and provide antioxidant protection while curling. Combined with even airflow from the blow dryer, this allows color-protecting products to penetrate more easily and prolongs the color's longevity. On the other hand, after infrared light irradiation, applying cool air through the blow dryer accelerates cuticle closure, locking in moisture and shine components, resulting in more lustrous hair after styling and solving the problem of dryness and dullness.

[0044] Preferably, a 630nm red light or an 830nm near-infrared light can be installed on the inner side of the side shell 30. This allows for simultaneous phototherapy and styling: For frizzy and split ends, the 630nm red light directly irradiates the hair strands, promoting cuticle repair and closure. Combined with the hot / cool air from the blow-dryer, the hair receives treatment during the styling process, effectively reducing split ends and frizz. For fragile and easily broken hair, the 830nm near-infrared light penetrates deep into the hair core, enhancing the toughness of the keratin structure and reducing the risk of breakage due to pulling and heating during curling, making it especially suitable for damaged hair that is frequently permed and dyed.

[0045] Reference Figure 7 The side slot 32 has symmetrical first curved portions 320 on both sides, and the lower end of the first curved portions 320 is connected to a second curved portion 321. The distance between the first curved portions 320 on both sides of the side slot 32 is less than the distance between the second curved portions 321 on both sides of the side slot 32. The upper ends of both sides of the side slot 32 have arc-shaped transition portions 322.

[0046] Specifically, the side slot 32 provides a clear path for inserting hair, making it easier to place the hair strand into the curling cavity 33 during operation. The first curved portion 320 and the second curved portion 321 of the side slot 32 form a design that is wider at the bottom and narrower at the top, making it less likely for the hair strand to detach after entering the curling cavity 33. The upper arc-shaped transition portion 322 reduces mechanical pulling damage when inserting the hair strand.

[0047] In summary, this utility model, through its innovative design of the curling section structure, significantly improves the curling effect, efficiency, and applicability, demonstrating a certain level of technological advancement.
