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. Background Technology

[0002] Automatic curling irons (or automatic hair curlers, hair curlers) are popular because they are easy to use and can help users quickly create curly hairstyles. These devices typically include a curling section for winding and heating the hair. The curling section generally has an outer barrel, inside which a curling cavity is formed to hold and wind the hair strands.

[0003] In existing technologies, these automatic curling irons primarily rely on heat conduction as the main method for heating and styling hair. The hair is wrapped around the inner wall of the curling barrel, and heat is transferred from the heating element through the barrel wall to the hair layer in contact with it. Heat needs to be gradually conducted from the barrel wall into the hair strands. This slow heat transfer is particularly noticeable for thicker or coarser hair strands, resulting in a longer time required to reach the desired styling temperature and increased waiting time for the user. Furthermore, uneven heating of the hair can lead to unsatisfactory curling results.

[0004] Therefore, those skilled in the art have been seeking methods to improve the heating and styling effects of automatic curling irons. While existing technologies may have made improvements in the layout of heating elements, temperature control precision, or surface materials of the curling barrel (such as ceramic coatings), relying solely on heat conduction as the basic heating method inherently suffers from low efficiency, uneven heating, and high risk of damage, making fundamental solutions difficult to achieve. There is an urgent need for an innovative solution that can overcome the limitations of pure heat conduction, significantly improve heating efficiency, uniformity, and styling effects, while simultaneously reducing the risk of thermal damage. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an automatic hair curling iron that has a uniform and efficient hair heating and styling effect.

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

[0007] An automatic hair curling iron includes a handle and a curling part disposed on the handle; the curling part includes an outer tube, and a curling cavity is formed inside the outer tube, and a curling post with a heating function is disposed inside the curling cavity.

[0008] The outer cylinder includes two side shells, and each side shell has an air blower facing the curling cavity on its inner wall. The air blowers in the two side shells are arranged opposite each other.

[0009] The air outlet is elongated in the vertical direction of the side shell, and guide strips are evenly distributed on the air outlet.

[0010] The inner side of the side housing is provided with a far-infrared light strip, 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 far-infrared light strip.

[0011] The curling post is vertically positioned in the middle of the curling cavity, and the curling section also includes a rotatable curling lever located outside the curling post.

[0012] The upper end of the curling post is provided with a hair clamping component, which includes two side flaps and a hair clamping groove between the side flaps.

[0013] The side lobe is provided with friction ridges.

[0014] Side slots are formed between the side shells, and the side slots are arranged symmetrically front and back.

[0015] 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.

[0016] The upper ends of both sides of the side slot form an arc-shaped transition section.

[0017] The beneficial effects of this utility model include at least the following:

[0018] 1. The hairdryer nozzle actively delivers hot air into the curling chamber, which, combined with the heated curling posts inside, creates convection heating that penetrates the hair strands. Compared to traditional curling irons that rely on the outer wall of the curling posts for heating, the hot air generated by the hairdryer nozzle within the curling chamber can effectively act on both 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 hairdryer nozzle can also actively deliver cool air into the curling chamber. After the hair strands enter the curling chamber, they are first heated and softened by the curling posts, making them easier to shape. Then, the cool air from the hairdryer nozzle quickly cools and sets the style, enhancing its durability. This alternating hot and cold design not only significantly improves the hair styling effect but also effectively reduces the damage caused by high temperatures to the hair, balancing aesthetics and hair care needs.

[0019] 2. The air outlets are set opposite each other on the inner sides of the two side shells, forming a double-sided opposing airflow that covers the entire cross-section of the curling cavity, eliminating dead angles in single-point air supply, ensuring that all parts of the hair are heated evenly, and avoiding local overheating damage.

[0020] 3. An infrared light strip is installed on the inner side of the side shell, enabling simultaneous phototherapy and styling. The infrared lights are integrated into the inner wall of the side shell and distributed alongside the elongated air outlet, ensuring that the phototherapy coverage area and the hot air action area highly overlap, achieving synchronous and uniform photothermal effects without the need for additional operating steps, thus improving the user experience.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 An automatic hair curling iron includes a handle 1 and a curling part 2 disposed on the handle 1; the curling part 2 includes an outer tube 3, a curling cavity 33 is formed inside the outer tube 3, and a curling post 4 with a heating function is disposed inside the curling cavity 33.

[0027] The outer cylinder 3 includes two side shells 30, and each side shell 30 has an air blower 31 facing the curling cavity 33 on its inner wall. The air blowers 31 in the two side shells 30 are arranged opposite to each other.

[0028] Specifically, the blower nozzle 31 actively delivers hot air into the curling chamber 33. Combined with the heat-generating curling posts 4 within the curling chamber 33, this creates convection heating that penetrates the hair strands. Compared to traditional curling irons that rely on the outer wall of the curling posts for heating, the hot air generated by the blower nozzle 31 within the curling chamber 33 can effectively reach both 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 delivers cold air for rapid cooling and setting, 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 caused by high temperatures to the hair, balancing aesthetics and hair care needs.

[0029] The air outlets are positioned opposite each other on the inner sides of the two side shells, forming a double-sided opposing airflow that covers the entire cross-section of the curling cavity, eliminating dead zones in single-point airflow, ensuring that all parts of the hair are heated evenly, and avoiding local overheating damage.

[0030] Reference Figure 2 , Figure 4 The air outlet 31 is elongated in the vertical direction of the side housing 30, and guide strips 310 are evenly arranged on the air outlet 31.

[0031] Specifically, the air outlet 31 is elongated along the vertical direction of the side shell to achieve full vertical air coverage and ensure that the hair strands are heated evenly from top to bottom. The air guide strip 310 divides the airflow into multiple directional fine streams, enhancing the airflow's ability to penetrate thick hair strands, solving the problem of "uneven heating between inner and outer layers," while reducing wind speed attenuation and improving heat utilization.

[0032] Reference Figure 3 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 and distributing them side by side with the elongated air outlets 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.

[0033] 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.

[0034] 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.

[0035] Reference Figure 1 , Figure 2The curling post 4 is vertically positioned in the middle of the curling chamber 33, and the curling section 2 also includes a rotatable curling lever 5 located outside the curling post 4. Specifically, when performing the curling operation, the device is activated, the curling lever 5 rotates, and the hot air generated by the airflow from the blower 31 wraps around the hair strands while blowing and drying them, effectively reducing hair tangles and making the curls more fluffy and natural.

[0036] A hair-clamping component 6 is provided at the upper end of the curling post 4. The hair-clamping component 6 includes two side flaps 60 and a hair-clamping groove 61 between the side flaps 60. Friction ridges 62 are provided on the side flaps 60. Specifically, during the curling operation, the hair-clamping 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 chamber 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-clamping groove 61 can fix the upper end of the hair bundle and prevent the hair bundle from shifting due to airflow impact or the wrapping of the curling lever 5. The friction ridges 62 increase the clamping force and prevent the wet and slippery hair bundle from falling off, especially suitable for high-speed airflow environments.

[0037] Reference Figure 3 A side slot 32 is formed between the side shells 30, and the side slot 32 is symmetrically arranged front and back. A symmetrical first curved portion 320 is formed on both sides of the side slot 32, and a second curved portion 321 is connected to the lower end of the first curved portion 320. The distance between the first curved portions 320 on both sides of the side slot 32 is smaller than the distance between the second curved portions 321 on both sides of the side slot 32. An arc-shaped transition portion 322 is formed at the upper end of both sides of the side slot 32.

[0038] 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.

[0039] In summary, the curling iron with a blower nozzle 31 provided by this utility model achieves significant technological progress by setting blower nozzles 31 facing the curling cavity 33 on the inner walls of the two side shells 30 of the outer cylinder 3 of the curling part 2 and by adopting specific structural optimization.
