Description

Technical Field

[0001] This utility model belongs to the field of beauty and hair technology, specifically relating to a cooling structure for a hair curling tube. Background Technology

[0002] Hair curling irons, as common hair styling tools, primarily function to heat and style hair using hot air. Currently, most hair curling irons on the market use a single-layer barrel structure, with hot air entering directly into the barrel through the inlet and then blowing onto the hair through vents on the barrel wall. This type of structure has significant drawbacks: First, the hot air flow path is short and lacks sufficient buffering and cooling, resulting in excessively high outlet temperatures that can easily cause burns or dry, damaged hair. Second, the direct airflow is concentrated and uneven, easily causing localized overheating or blowing hair frizz, affecting styling results and user comfort. Third, common hair clamping structures usually do not consider ventilation, leading to heat buildup in the clamping area and further increasing the risk of burns. Furthermore, the simple overall structure lacks optimized design for airflow guidance and distribution, resulting in high energy consumption and a poor user experience. Therefore, there is an urgent need for a hair curling iron structure that can effectively reduce outlet temperature, evenly distribute airflow, and improve user safety. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] like Figure 1-3 As shown, this utility model provides a hair curling iron cooling structure, including an inner cylinder 1, an outer cylinder 2 sleeved outside the inner cylinder 1, and a clamping assembly 3 disposed on the outer wall of the outer cylinder 2. Both the inner cylinder 1 and the outer cylinder 2 are elongated cylinders, with a gap between the outer wall of the inner cylinder 1 and the inner wall of the outer cylinder 2, thus forming an annular air cavity 21. The surface of the outer cylinder 2 is provided with several air outlets 22, which connect the air cavity 21 and the outside of the outer cylinder 2. One axial end of the inner cylinder 1 is provided with an air inlet 11 connecting to the interior of the inner cylinder 1. The inner cylinder 1 includes several arc-shaped air guide vanes 12, which are connected sequentially front to back. The inner cylinder 1 is formed around the outer cylinder, and air guide holes 13 are formed between adjacent air guide vanes 12. The air outlet direction of the air guide hole 13 is inclined to the outer wall of the corresponding air guide vane 12. The air guide hole 13 connects the interior of the inner cylinder 1 and the air cavity 21. Specifically, the angle between the air outlet direction of the air guide hole 13 and the outer wall of the air guide vane 12 is 0-90 degrees. This inclined structure causes the hot air to generate a Coanda effect with the outer wall of the air guide vane 12 when it flows, so that the hot air circulates on the outer wall of the arc-shaped air guide vane 12 and flows around in the air cavity 21, extending the flow path of the hot air. In use, the hair is first clamped between the outer wall of the outer cylinder 2 and the clamping assembly 3. Hot air enters the inner cylinder 1 from the air inlet 11 and, guided by the arc-shaped air guide 12, enters the air cavity 21 through the air guide hole 13. Due to the arc-shaped structure of the air guide 12 and the inclined air outlet direction of the air guide hole 13, the hot air forms a wall-attached circulation around the outer wall of the air guide 12 in the air cavity 21. This process effectively extends the flow path of the hot air, thereby significantly reducing the temperature and air pressure of the hot air. Finally, the cooled and stabilized airflow is blown evenly and gently from the air outlet 22 of the outer cylinder 2 onto the hair, avoiding the risk of burns caused by direct high-temperature airflow, while improving styling comfort and safety.

[0029] Most hair curlers on the market use a single-tube structure, that is, only the outer tube 2 is set. After the hot air enters the tube from the air inlet 11, it blows directly onto the hair through the air outlet 22 without sufficient buffering and guidance. At this time, the temperature and air pressure of the hot air are very high, which can easily cause hair burns, dryness and damage, and also easily mess up the hair strands, affecting the styling effect and safety of use. In order to solve this problem, this application sets the outer tube 2 and the inner tube 1, and the air cavity 21 is formed between the outer tube 2 and the inner tube 1. Then, through the arc-shaped air guide 12 of the inner tube 1, the hot air flows around the air cavity 21 along the arc-shaped path. This structure significantly extends the hot air flow path, thereby effectively reducing the temperature and pressure of the final blown airflow and improving the comfort and safety of use.

[0030] Specifically, such as Figure 3 As shown, in one embodiment of this utility model, the air guide vane 12 is provided with a first cross-section 121 and a second cross-section 122 at its ends, respectively. The first cross-section 121 and the second cross-section 122 of two adjacent air guide vanes 12 are spaced apart and together form the air guide hole 13. The first cross-section 121 and the second cross-section 122 are inclined relative to the radial direction of the inner cylinder 1, and the inclination direction of the first cross-section 121 and the second cross-section 122 follows the arc direction of the air guide vane 12 itself, so that the air guide hole 13... Similarly, the air guide vane 12 is inclined to follow its arc shape. This structural design allows the hot air to initially form an arc-shaped flow trend under the guidance of the arc-shaped air guide vane 12. When passing through the inclined air guide hole 13, the direction of the air guide hole 13 is consistent with the airflow direction, avoiding a sharp change in the flow direction and maximizing the preservation of the original motion inertia of the airflow. This allows the hot air to smoothly enter the air cavity 21 with an arc-shaped trajectory and form a stable and continuous circulating flow in the cavity, thereby enhancing the cooling and pressure equalization effect.

[0031] In another embodiment, the first section 121 and the second section 122 are arranged radially along the inner cylinder 1, and the air guide hole 13 is also arranged radially along the inner cylinder 1.

[0032] Specifically, such as Figure 2As shown, in one embodiment of this utility model, the inner cylinder 1 is provided with an air distributor 4. The end of the air distributor 4 axially close to the air inlet 11 is provided with a connecting seat 5. The diameter of the connecting seat 5 is larger than the diameter of the outer cylinder 2. The inner cylinder 1 is sleeved on the air distributor 4 and connected to the connecting seat 5 at one axial end. The outer cylinder 2 is further sleeved on the inner cylinder 1 and is also connected to the connecting seat 5 at one axial end. The outer cylinder 2 and the inner cylinder 1 are spaced apart to form the air cavity 21. The end of the connecting seat 5 away from the air distributor 4 is the air inlet end, which is the air inlet direction of the air inlet 11. During operation, hot air flows in from the air inlet 11 and passes through the connecting seat 5, the air distributor 4, the inner cylinder 1 and the outer cylinder 2 in sequence, and finally blows evenly and gently onto the hair.

[0033] Furthermore, such as Figure 3-4 As shown in the figure, the air distributor 4 includes an axially extending frame 41. It can be seen from the figure that the frame 41 has six rod-shaped members, and multiple air distribution layers 42 are provided on the frame 41. The air distribution layers 42 have a ring structure and are spaced apart along the axial direction of the frame 41. For example... Figure 3 As shown, the air distribution layer 42 includes several arc-shaped air distribution plates 421 arranged in a ring around the axial direction. The air distribution plates 421 are connected end to end between two frames 41. The six air distribution plates 421 are connected end to end to form a complete annular air distribution layer 42. An air distribution groove 43 is formed between axially adjacent air distribution plates 421. After the hot air enters the air distributor 4, some of the hot air will be intercepted by the air distribution plates 421 and guided into the air distribution groove 43, and then come into contact with the inner cylinder 1. This structural design can realize the active distribution and guidance of hot air, thereby significantly improving the uniformity of air outlet. If the air distributor 4 is not set, the hot air with a faster flow rate is easy to gather at the end away from the air inlet 11, resulting in uneven air outlet. However, through the cooperation of the air distribution plates 421 and the air distribution groove 43, part of the hot air is intercepted and the hot air is evenly dispersed and then comes into contact with the inner cylinder 1, ultimately achieving a stable and consistent air outlet effect.

[0034] Furthermore, such as Figure 3 As shown, the air distribution plate 421 is also arc-shaped, and the arc-shaped contour of the air distribution plate 421 matches the arc-shaped contour of the air guide plate 12, from Figure 3 As can be seen, the air distribution plate 421 is close to or maintains a very small gap with the air guide plate 12. This structure ensures that the gap between the inner wall of the inner cylinder 1 and the outer wall of the air distributor 4 is not too large, ensuring that part of the hot air entering the air distribution groove 43 can only be discharged through the air guide hole 13 on the inner cylinder 1 corresponding to the air distribution groove 43, thereby avoiding airflow interference and further improving the uniformity and stability of the air outlet.

[0035] Specifically, such as Figure 2 , 5 As shown in Figure 6, in one embodiment of this utility model, the peripheral wall of the connecting seat 5 is elastically hinged to the clamping assembly 3. The clamping assembly 3 includes a clamp 31, a finger buckle 32, and an elastic element 34. The finger buckle 32 is provided with a connecting part 321, a pressing part 322, and a rotating part 323 disposed between the connecting part 321 and the pressing part 322. One end of the clamp 31 is connected to the connecting part 321, and the other end abuts against the peripheral wall of the outer cylinder 2. The finger buckle 32 is hinged to the peripheral wall of the connecting seat 5, and the elastic element 34 is disposed at the hinge, so that the clamp 31 continuously presses against the peripheral wall of the outer cylinder 2.

[0036] Furthermore, the connecting seat 5 has two fixed seats 51 on its peripheral wall, and the rotating part 323 of the finger buckle 32 is disposed between the two fixed seats 51. The clamping assembly 3 also includes a rotating shaft 33, which passes through both the fixed seat 51 and the rotating part 323. The elastic member 34 is sleeved on the rotating shaft 33. The elastic member 34 includes a fixed end 341 connected to the connecting seat 5 and a free end 342 abutting against the pressing part 322 of the finger buckle 32. The connecting seat 5 has a fixing hole 52, and the fixed end 341 of the elastic member 34 is inserted into the fixing hole 52. like Figure 6 As shown, at this time, the fixed end 341 and the free end 342 of the elastic member 34 are in an elastic compression state. The free end 342 generates an upward elastic force and acts on the pressing part 322, causing the pressing part 322 to move upward around the rotating part 323, thereby driving the connecting part 321 to move downward around the rotating part 323, and finally causing the clamp 31 connected to the connecting part 321 to abut against the outer wall of the outer cylinder 2. When hair needs to be clamped, simply press down on the pressing part 322 of the finger buckle 32, and the connecting part 321 and the clip 31 will lift up. Place the hair between the clip 31 and the outer tube 2, release the press, and under the elastic action of the elastic member 34, the clip 31 will return to its original position and abut against the outer tube 2 to clamp the hair.

[0037] Furthermore, during the pressing and resetting process, the free end 342 of the elastic element 34 will slide relative to the pressing part 322 of the finger buckle 32. Since the free end 342 is made of metal and the pressing part 322 is made of plastic, after long-term use, the free end 342 will develop scratches on the pressing part 322. At the same time, the friction of such relative sliding is relatively large, making the pressing and resetting process not smooth enough. To solve this problem, such as Figure 5-6As shown, a ball bearing 343 is provided at the free end 342 of the elastic member 34, so that the sliding of the free end 342 and the pressing part 322 becomes rolling. This structural design can reduce friction, making the pressing process smoother and more fluid, and reducing the force required for pressing. On the other hand, it can prevent the free end 342 from scratching the pressing part 322, thus increasing its service life.

[0038] Furthermore, such as Figure 7 As shown, the clip 31 is provided with several through holes 311 that communicate with the air outlet holes 22 on the surface of the outer cylinder 2. When hair is clamped between the clip 31 and the outer cylinder 2, if the clip 31 is not provided with the through holes 311, hot air will blow from the outer cylinder 2 to the hair and accumulate between the clip 31 and the outer cylinder 2, causing the hair temperature in that area to rise continuously, thereby burning the hair. By providing the through holes 311, the hot air can be blown out from the through holes 311 of the clip 31 after it blows onto the hair, without accumulation, thus avoiding burning the hair.

[0039] Specifically, in one embodiment of this utility model, a cover 6 is provided at the end of the inner cylinder 1 that is axially away from the air inlet 11. The outer peripheral wall of the cover 6 is smoothly connected to the outer peripheral wall of the outer cylinder 2. On the one hand, the cover 6 forms an axial clamping position with the connecting seat 5, and serves as a fixing point at both ends of the inner cylinder 1 and the outer cylinder 2 to fix them together. On the other hand, the cover 6 can cover the inner cylinder 1, the outer cylinder 2 and the air cavity 21 to prevent hot air from leaking out and resulting in low air outlet efficiency.

[0040] The following is a detailed explanation of the working principle of this utility model; Hot air enters through the air inlet 11 at the end of the inner cylinder 1, first flowing through the air distributor 4. The air distributor 4 disperses and initially distributes the hot air through the air distribution layer 42 and the air distribution groove 43, avoiding uneven airflow caused by concentrated hot air. Subsequently, guided by the arc-shaped air guide 12, the hot air enters the annular air cavity 21 between the inner cylinder 1 and the outer cylinder 2 through the inclined air guide hole 13. Due to the arc-shaped and inclined layout of the air guide 12 and the air guide hole 13, the hot air forms a swirling flow in the air cavity 21, extending the flow path and effectively reducing the airflow temperature and pressure. The cooled airflow is finally blown evenly and gently onto the hair through the air outlet 22 on the outer cylinder 2. Throughout the process, the airflow undergoes multiple guidance, dispersion, and buffering processes, achieving a highly efficient, uniform, and low-temperature air delivery effect.

[0041] The innovation of this utility model lies in: This product effectively overcomes the shortcomings of traditional hair curlers in terms of temperature control, airflow distribution, and safety, offering the following significant benefits: First, the double-layered body, combined with a ring-shaped air chamber and an arc-shaped air guide structure, achieves swirling cooling of hot air, significantly reducing the outlet temperature, preventing hair burns, and improving safety. Second, the synergistic effect of the air distributor and air guide vanes ensures even and gentle distribution of hot air, effectively preventing localized overheating and hair blowing out, thus improving styling results and comfort. Third, through-holes in the clamping components prevent heat buildup, further protecting hair from damage. The overall structure is scientifically designed with optimized airflow paths, achieving efficient cooling while maintaining styling efficiency, combining energy saving and practicality.
