[0032] Referring to the specific embodiments shown in FIGS. 1 to 5, the present application discloses a curling head structure, comprising: a curling body 10, a plurality of open cavities 11 are uniformly distributed on the curling body 10, an air outlet strip 20 is installed on the open cavity 11, the air outlet strip 20 is provided with a wind collecting cavity 21 communicated with the inside of the curling body 10 along the length direction, and the bottom of the wind collecting cavity 21 is provided with an air outlet 22. The air flow enters the inside of the curling body 10, and the wind collecting cavity 21 guides the air flow to blow out along the air outlet 22.

[0033] Specifically, after the air flow enters the inside of the curling body 10, the wind collecting cavity 21 guides the air flow to blow out along the air outlet 22, so that the air flow blown out of the air outlet 22 forms a Coanda effect, and a plurality of air outlets 22 cooperate, that is, an automatic curling effect of air flow rotating 360 degrees around can be formed, the curling speed is improved, and the user experience is improved. In addition, the curling body 10 is uniformly distributed with a plurality of open cavities 11, this design makes the curling head can cover a wider hair area when in use, so as to more evenly disperse and distribute the wind power, the air outlet strip 20 is installed in the open cavity 11, and the wind collecting cavity 21 communicated with the inside of the curling body 10 is provided along the length direction, this structure makes the wind power can be effectively guided and gathered after entering the curling body 10, and then blown out through the air outlet 22.

[0034] Preferably, the number of air outlet strips 20 is six, evenly and annularly distributed on the curling body 10, so as to achieve the best curling effect.

[0035] In an embodiment, the opening of the air gathering cavity 21 gradually narrows from inside to outside along the curling body 10.

[0036] Specifically, since the opening of the air gathering cavity 21 gradually narrows from inside to outside along the curling body 10, this design can effectively gather the air flow or wind power entering the inside of the curling body 10 into a smaller area, and this gathering effect makes the wind power more concentrated at the air outlet 22, thereby improving the wind power density and blowing speed. In addition, the gradually narrowing design of the opening can limit and guide the wind power to a certain extent when passing through the air gathering cavity 21, thereby ensuring that the wind power can be more evenly distributed on the working surface of the curling head when blowing out, which is very important for ensuring the consistency of the hair styling or drying effect. In addition, the gradually narrowing opening of the air gathering cavity 21 can reduce the turbulence and noise generated when the wind power passes through, and at the same time reduce the vibration of the curling head when working, which has a positive significance for improving the user experience and comfort.

[0037] In an embodiment, the air outlet 22 is obliquely arranged.

[0038] Specifically, the air outlet 22 is obliquely arranged, and the air flow blown out along the air outlet 22 passes through the pipe wall of the curling body 10 to form a Coanda effect, that is, the air flow will flow along the convex object surface (pipe wall), which makes the wind power more directly guide to the target area such as hair, thereby improving the utilization efficiency of the wind power. In addition, the Coanda effect makes the wind power be compressed and guided when passing through the pipe wall, forming a more concentrated and stable air flow, which can more effectively act on the hair, especially the roots of the hair and the scalp, thereby accelerating the curling speed and improving the use effect. In addition, the oblique air outlet 22 and the Coanda effect work together to make the wind power more gently act on the hair and scalp, and this gentle wind power can reduce the discomfort caused by direct blowing, especially when using high-temperature wind, which can further improve the user's comfort.

[0039] In an embodiment, the two sides of the opening cavity 11 are respectively provided with a first mounting groove 12 and a second mounting groove 13, and the air outlet strip 20 is provided with a first connecting protrusion 23 and a second connecting protrusion 24 corresponding to the first mounting groove 12 and the second mounting groove 13.

[0040] Specifically, the two sides of the opening cavity 11 are respectively provided with a first mounting groove 12 and a second mounting groove 13, and the air outlet strip 20 is correspondingly provided with a first connecting protrusion 23 and a second connecting protrusion 24. This design enables the air outlet strip 20 to be accurately embedded into the opening cavity 11 and stably connected through the cooperation of the first connecting protrusion 23 and the second connecting protrusion 24 with the first mounting groove 12 and the second mounting groove 13. This stable connection helps to ensure that the air outlet strip 20 will not loosen or fall off due to wind force or other external forces during use, thereby ensuring the use effect and safety of the curling iron. In addition, the air outlet strip 20 with the connecting protrusions can be easily inserted into the corresponding mounting grooves of the opening cavity 11, and the installation can be completed without complex tools or steps. This design not only improves the production efficiency of the curling iron, but also facilitates the replacement or maintenance of the air outlet strip 20 during use. In addition, by providing mounting grooves on both sides of the opening cavity 11 and corresponding connecting protrusions on the air outlet strip 20, the structure of the curling iron is more compact and integrated, which helps to improve the durability and impact resistance of the curling iron, and also makes the curling iron more convenient to carry and use.

[0041] In an embodiment, the air outlet strip 20 is provided with a plurality of guide bones 25 along the length direction, so that the air outlet 22 forms a plurality of small air outlet holes.

[0042] Specifically, by providing a plurality of guide bones 25, the air outlet 22 is divided into a plurality of small air outlet holes. This design enables the wind force to be more evenly distributed when blowing out, avoiding the situation of excessive concentration or dispersion of wind force. The design of small air outlet holes can ensure that the wind force can act more finely on the hair, especially in the case of requiring detailed styling or blow-drying. This design can greatly improve the use effect. In addition, the guide bones 25 not only serve to divide the air outlet 22, but also have a certain guiding effect, which can guide the wind force to blow in a specific direction, thereby more accurately meeting the needs of users. For example, when rapid blow-drying of hair is required, the arrangement and angle of the guide bones 25 can be adjusted to make the wind force more concentratedly blow to the roots of the hair and the scalp, thereby speeding up the blow-drying speed. In addition, the design of small air outlet holes makes the wind force more gentle when blowing out, reducing the discomfort caused by direct blowing. This is particularly important for users with sensitive scalp or soft hair quality. At the same time, since the wind force is more evenly distributed, the noise and vibration of the wind force during transmission are also reduced, further improving the comfort of use.

[0043] In an embodiment, the guide bones 25 are arranged obliquely.

[0044] Specifically, the inclination of the guide bones 25 allows the airflow to be blown obliquely, and this design makes the wind force no longer directly perpendicular to the surface of the hair curling head, but has a certain inclination angle. This oblique airflow guide helps to more accurately control the direction of the wind force, ensuring that the wind force can be blown to the target area according to the predetermined trajectory, thereby enhancing the hair curling effect. In addition, the obliquely blown airflow forms a concentrated airflow beam during the flow process, and this concentrated airflow beam has stronger penetration, which can more deeply penetrate into the roots of the hair and the scalp. During the hair drying or styling process, this enhanced penetration helps to dry the hair faster or achieve a more delicate styling effect. In addition, the obliquely arranged guide bones 25 allow the wind force to be blown obliquely, reducing the area and intensity of the wind force directly blowing on the scalp, thereby reducing the discomfort of the user. For users with sensitive scalp, this design can significantly improve the comfort of use. In addition, by adjusting the inclination angle and arrangement of the guide bones 25, different directions and strengths of oblique wind force can be formed. This design allows the hair curling head to adapt to the needs of different hair types and styles; for example: for fine and soft hair or styles that require delicate styling, a smaller inclination angle and a more dense arrangement of guide bones can be used to obtain a softer and more delicate wind effect; while for thick and hard hair or occasions that require rapid drying, the inclination angle and the distance between the guide bones 25 can be increased to obtain stronger and more extensive wind coverage.

[0045] In an embodiment, the inclination angle of the guide bones 25 is 55-80 degrees.

[0046] Specifically, the inclination angle of the guide bones 25 is between 55-80 degrees, which can ensure that the wind force is blown at a certain inclination angle. This design optimizes the guidance of the wind force, allowing the wind force to more accurately act on the target area. At the same time, the obliquely blown wind force helps to form more extensive wind coverage, making the wind distribution more uniform. In addition, the guide bones 25 with an inclination angle of 55-80 degrees reduce the area and intensity of the wind force directly blowing on the scalp, thereby reducing the discomfort of the user. This design is particularly suitable for users with sensitive scalp, and can improve their comfort of use. In addition, the inclination angle of the guide bones 25 is 55-80 degrees, which is better for hair curling.

[0047] In an embodiment, the bottom of the hair curling body 10 is provided with a connecting seat 30, and a wind guide ring 40 is further arranged between the connecting seat 30 and the hair curling body 10. The bottom of the air outlet strip 20 abuts against the wind guide ring 40.

[0048] Specifically, the airflow blown from the host first passes through the connecting seat 30 and then enters the inside of the curling body 10 along the air guide ring 40 to avoid the airflow directly entering the air collecting cavity 21 after passing through the connecting seat 30, that is, the arrangement of the air guide ring 40 ensures that the airflow blown from the host first passes through the connecting seat 30 and then enters the inside of the curling body 10 along the air guide ring 40, which can avoid the airflow directly impacting the connecting seat 30 and then directly entering the air collecting cavity 21, thereby ensuring the uniform distribution and guidance of the airflow in the curling body 10. In addition, through the guidance and distribution of the air guide ring 40, the airflow can be more uniformly distributed on the air outlet strip 20 of the curling body 10, thereby providing more stable and more uniform air output. In addition, after the airflow passes through the buffering and guidance of the air guide ring 40, the air force will be more gentle, reducing the possibility of directly impacting the user's scalp, improving the comfort of use, avoiding the noise and vibration that may be generated after the airflow directly impacting the connecting seat 30, and further improving the comfort of use.

[0049] Among them, the air guide ring 40 and the connecting seat 30 can be a split structure or an integrated structure.

[0050] Specifically, the split structure allows the air guide ring 40 and the connecting seat 30 to be manufactured and installed separately, which greatly simplifies the production and assembly process, and if any of the components is damaged or needs to be repaired, it can be replaced individually without replacing the entire structure, reducing maintenance costs. In addition, the split structure allows designers to select air guide rings 40 and connecting seats 30 of different materials, shapes or sizes according to actual needs, thereby meeting different design requirements and use scenarios. While the integrated structure directly combines the air guide ring 40 and the connecting seat 30 together to form a whole, such a structure is more stable and less likely to loosen or be damaged. In addition, the integrated structure reduces the gap between the components, thereby reducing air or airflow leakage during transmission and improving the overall air transmission efficiency.

[0051] In an embodiment, the top of the curling body 10 is also provided with a hand holding end 14.

[0052] Specifically, the arrangement of the hand holding end 14 blocks the upper end of the curling body 10 so that the airflow cannot be blown out from the upper end, avoiding the loss of airflow and improving the hair styling effect, and also improving the aesthetics of the overall structure. In addition, the hand holding end 14 as the top part of the curling body 10 provides a comfortable gripping point for the user, who can easily hold the hand holding end 14 for two-handed operation, avoiding the risk of being burned, and also being able to stably operate the curling head to ensure the smooth progress of the curling process. In addition, by rotating the hand holding end 14, the user can more conveniently wind the hair on the curling body 10 to form the desired curling effect, which simplifies the curling operation and enables the user to more easily complete the curling process, improving the convenience of use.

[0053] The application also discloses a hair curler comprising the curling head structure.

[0054] Specifically, the curling head structure is installed on a main machine through a connecting seat, and the main machine is used for providing power supply and cold and hot air. The main machine adopts the prior art and will not be described in detail here.

[0055] Specifically, the hair curler is provided with a plurality of opening cavities uniformly distributed on the curling body, and the opening cavities are provided with air outlet strips. The air outlet strips are provided with air collecting cavities communicated with the inside of the curling body along the length direction. The cavity bottom of the air collecting cavities is provided with air outlets. After the airflow enters the inside of the curling body, the air collecting cavities guide the airflow to blow out along the air outlets. The airflow blown out of the air outlets forms a Coanda effect, and a plurality of air outlets cooperate, so as to form an automatic curling effect that the airflow rotates around 360 degrees, improve the curling speed, and obviously improve the use experience of the hair curler.

[0056] The above embodiment is a preferred implementation scheme of the application. In addition, the application can also be implemented in other ways, and any obvious replacement without departing from the technical scheme concept is within the protection scope of the application.
