Description

Technical Field

[0001] This utility model relates to the field of hair styling technology, specifically to a hair curling accessory and a hair dryer. Background Technology

[0002] Currently, most hair dryers on the market directly heat the hair to denature its proteins, thus styling it. However, this method easily leads to hair damage and frizz. With technological advancements, accessories and devices that utilize the Coanda effect for hair styling have emerged. These accessories typically employ multiple air outlet zones on an internal frame and multiple air outlet holes on an air outlet plate, with each zone corresponding to one outlet hole. However, this design can cause interference between the air outlet zones, preventing the timely removal of hot air from the device and slowing down the styling process. Furthermore, the need for multiple air outlet zones on each air outlet plate's frame makes manufacturing inconvenient. Therefore, providing a hair curling accessory that is easy to manufacture, offers higher styling efficiency, produces voluminous and airy curls, and achieves a more ideal overall curl effect is a pressing issue in this field. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a hair curling accessory with better airflow guiding effect.

[0004] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0005] A hair curling accessory includes: a frame having at least one first connecting port arranged circumferentially thereon and extending axially along the frame, each first connecting port constituting an independent first air outlet area; and multiple air outlet plates arranged sequentially along the circumferential direction of the frame on the outer periphery of the frame, with at least one air outlet hole provided on each air outlet plate at a position corresponding to the first air outlet area. By setting multiple first connecting ports on the circumference of the frame, and multiple air outlets corresponding to the multiple first connecting ports, each air outlet has multiple air holes. When the hair curling accessory is used, the air flows from one end of the frame to the other, then flows through the first connecting ports and is discharged through the multiple air holes. Since the multiple air outlets are arranged in a circle around the circumference of the frame, the hair is driven by the air and eventually wrapped around the outer periphery of the hair curling accessory in an orderly manner. Compared with the setting method of one first connecting port corresponding to one air hole, this application can quickly discharge the fluid, improve the efficiency of hair curling, and facilitate the processing and assembly of hair curling accessories. In particular, when the positions of the air holes on each air outlet are different, there is no need to limit the installation position of the air outlet, which greatly improves the assembly efficiency.

[0006] Furthermore, all the air vents on the same air vent plate, when projected onto the frame, are located within the periphery of the corresponding first connecting opening. This arrangement of multiple air vents corresponding to the first connecting opening increases the overall air venting area of ​​the hair curling accessory, accelerates the exhaust speed, and thus improves the efficiency of the hair curling accessory's styling.

[0007] Furthermore, at least one air outlet panel has only one air outlet, and the air outlet extends along the axial direction of the frame. Only one ventilation hole is provided on the air outlet panel, and the size of the ventilation hole is adapted to the first connecting port, allowing air to be quickly discharged through the first connecting port and the air outlet.

[0008] Furthermore, multiple air outlets on each air outlet plate are spaced apart along the extension direction of the first connecting opening, wherein at least two of the multiple air outlets on each air outlet plate are staggered along the circumference of the frame; or multiple air outlets on each air outlet plate are arranged in a straight line, and the straight line is parallel to the axis of the frame. This staggered or parallel arrangement of air outlets not only creates a natural curly effect but also reduces hair pulling during the curling process, avoiding discomfort.

[0009] Furthermore, multiple air outlets on each air outlet plate are spaced apart along the extension direction of the first connecting opening, wherein the multiple air outlets on each air outlet plate are arranged in a spiral staggered pattern along the circumference of the frame. The spiral staggered arrangement of the air outlets allows the airflow to smoothly transition along the curve as it flows through the air outlets, increasing the airflow distribution range in space; the spiral arrangement helps to generate a certain rotational effect when the airflow flows along the surface of the air outlet plate, further improving the airflow guidance. The spiral flow and uniform distribution of airflow can better guide the air through the curling attachment, forming a continuous and stable airflow path, which is crucial for the curling effect. Smooth airflow guidance can effectively improve the precision and durability of hair curls, and reduce the styling instability caused by uneven airflow during the curling process.

[0010] Furthermore, the air outlet panel is snapped into place around the periphery of the first connecting port. This snapping connection improves the reliability of the air outlet panel's connection frame and further prevents the air outlet panel from loosening during use.

[0011] Furthermore, the two opposite sides of the air outlet panel are respectively connected to the edge of the first connecting port. The reliability of the connection is ensured by connecting both sides of the air outlet panel to the frame. Alternatively, the two longer sides of the air outlet panel can be connected to the edge of the first connecting port, or all four sides of the air outlet panel can be connected to the edge of the first connecting port.

[0012] Furthermore, the first side of the air outlet panel is a limiting side with a stop structure, and the second side of the air outlet panel is a snap-fit ​​side with a snap-fit ​​structure. The stop structure is embedded into the inner side of the first connecting port and cooperates with the edge of the first connecting port. The snap-fit ​​structure is snap-fitted with the edge of the first connecting port. By setting the stop structure and the snap-fit ​​structure on the opposite first and second sides of the air outlet panel respectively, the air outlet panel is simultaneously limited by two limiting methods, ensuring that the air outlet panel is relatively fixed and difficult to move once installed.

[0013] Furthermore, the air outlet of the air outlet plate has a windward surface facing the first connecting opening. An angle A is formed between the windward surface and the tangent L of the outer peripheral surface of the air outlet plate at the air outlet, and the angle A is greater than 120 degrees. By limiting the angle A, when the angle A is greater than 120 degrees, the cooperation between multiple air outlet plates can generate the Coanda effect, causing the hair to be attracted to the outer surface of the curling attachment by the air generated by the curling attachment.

[0014] Furthermore, the included angle A should be greater than or equal to 145 degrees and less than or equal to 155 degrees. A larger included angle A is not necessarily better; beyond a certain range, the overall curvature of the air vent decreases, which is detrimental to hair curling.

[0015] Furthermore, the included angle A is 150 degrees. At this angle, there is a better Coanda effect, which is beneficial for hair curling.

[0016] Furthermore, the air outlet of the air outlet plate has a windward surface facing the first connecting port, and the inner wall of the first connecting port also has a guide surface that connects with the windward surface. The guide surface and the windward surface form an angle B, which is greater than 120 degrees. 120 degrees is a reasonable minimum angle that can ensure that the airflow receives sufficient guiding force, so as to flow out smoothly and avoid turbulence and excessive dispersion.

[0017] Furthermore, the included angle B is greater than or equal to 145 degrees and less than or equal to 155 degrees. By limiting the included angle B to between 145 degrees and 155 degrees, a better flow guiding effect is achieved.

[0018] Furthermore, the distance L1 between the outer peripheral surface of the air outlet and the central axis of the frame is not unique in the circumferential direction of the air outlet. By setting the outer peripheral surface of the air outlet to an irregular arc shape, an air outlet gap is formed to prevent the hair from completely sticking to the outer surface of the air outlet, thus reducing uneven heating of the hair. That is, when the hair is completely sticking to the surface of the air outlet, the airflow will be greatly restricted, and the airflow cannot flow smoothly to every part of the hair. This may result in some areas of the hair being overheated, while other parts do not have enough airflow coverage. This uneven distribution of hot air will lead to unstable curling effect and may even damage the hair.

[0019] Furthermore, the distance L1 between the outer peripheral surface of the air outlet plate and the central axis of the frame gradually decreases along the middle of the air outlet plate towards the circumferential side edge. In this way, the thickness of the air outlet plate gradually decreases from the middle to both ends, creating an air outlet gap between the hair and the outer surface of the air outlet plate. Of course, other methods can also be used, such as the distance L1 between the outer peripheral surface of the air outlet plate and the central axis of the frame gradually decreasing along one end of the air outlet plate towards the other end.

[0020] This utility model also provides a hair dryer, including: a main body; and the aforementioned hair curling attachment, which is disposed on the main body. By using the hair curling attachment on the main body, when the main body is powered on, the generated fluid is discharged through the hair curling attachment. The discharged fluid can attract and orderly wrap hair to achieve a curled hairstyle.

[0021] This utility model has the following beneficial effects: By setting multiple first connecting ports in the circumference of the frame, and multiple air outlet plates corresponding to the multiple first connecting ports, each air outlet plate is provided with multiple air outlet holes. When the hair curling attachment is used, the air flows from one end of the frame to the other end, then flows through the first connecting ports and is discharged through the multiple air outlet holes. Since the multiple air outlet plates are arranged in a circle around the circumference of the frame, the hair is driven by the wind and finally wrapped around the outer periphery of the hair curling attachment in an orderly manner. Compared with the setting method of one first connecting port corresponding to one air outlet hole, this application can quickly discharge the fluid, improve the efficiency of hair curling, and facilitate the processing and assembly of hair curling attachments. In particular, when the positions of the air outlet holes on each air outlet plate are different, there is no need to limit the installation position of the air outlet plate, which greatly improves the assembly efficiency. This application solves the problems of low hair curling efficiency and lack of airy fluffiness in the existing hair curling attachments. Attached Figure Description

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other.

[0040] The technical solution of this utility model will now be described with reference to the accompanying drawings.

[0041] To address the problems of low curling efficiency and lack of volume in existing hair curling attachments, this invention provides a hair curling attachment and a hair dryer. The hair dryer includes a main body and the aforementioned hair curling attachment, which is mounted on the main body.

[0042] To achieve the above objectives, the technical solution provided by an embodiment of this utility model is as follows:

[0043] like Figures 1 to 7 As shown, this utility model provides a hair curling accessory. Figure 2As shown, the hair curling accessory is composed of multiple structures. The hair curling accessory mainly includes a frame 10 and air outlet plates 20. The frame 10 has at least one first connecting opening 11 arranged circumferentially thereafter, and the first connecting opening 11 extends axially along the frame 10, with each first connecting opening 11 forming an independent first air outlet area. There are multiple air outlet plates 20, and these multiple air outlet plates 20 are sequentially arranged circumferentially on the outer periphery of the frame 10, with at least one air outlet hole 21 provided at the position corresponding to the first air outlet area of ​​each air outlet plate 20.

[0044] Specifically, the frame 10 is configured to form an airflow cavity. The frame 10 has an airflow inlet that communicates with the airflow cavity. In this way, the airflow generated by the blower enters the airflow cavity through the airflow inlet. The airflow that enters the airflow cavity then flows out through the first connecting ports 11 in the circumference of the frame 10 and the multiple air outlet holes 21 on the air outlet plate 20 corresponding to the first air outlet area.

[0045] Since multiple air outlets 20 are arranged around the circumference of the frame 10, the airflow used for styling hair is discharged from different positions around the circumference of the air outlets 20, so that the hair is driven by the wind and eventually wrapped around the outer periphery of the curling attachment. There is no need to manually wrap the hair around the curling attachment, which makes the operation simple and improves the user experience.

[0046] In this application, the first communication port 11 on the skeleton 10 extends along the axial direction of the skeleton 10 (e.g., Figures 2 to 4 As shown), this makes the area of ​​the first connecting port 11 larger, so the area of ​​the first air outlet area formed by the first connecting port 11 is larger, and an independent first connecting port 11 can correspond to multiple air outlet holes 21 on the same air outlet plate 20, thus forming a form in which a first air outlet area corresponds to an independent air outlet plate 20.

[0047] Compared to the arrangement of multiple small-area first connecting ports 11 along the axial direction of the frame 10, with each of these ports corresponding to a single air outlet 21 on the same air outlet plate 20, the airflow from the first connecting ports 11 in this application is smoother. This effectively reduces wind resistance and increases the ventilation area, thereby increasing the overall airflow area of ​​the hair curling accessory and accelerating the exhaust speed, thus improving the styling efficiency of the hair curling accessory. Furthermore, by providing axially extending elongated holes (first connecting ports 11) on the frame 10, the processing efficiency of the frame 10 can be effectively improved, and the processing difficulty of the hair curling accessory can be effectively reduced.

[0048] Furthermore, since the air outlet plate 20 corresponds to an independent first air outlet area, that is, a long hole on the frame 10 directly corresponds to multiple air outlet holes 21 on the air outlet plate 20, the problem of low assembly error rate caused by the one-to-one correspondence between the small area first connecting port 11 and the small area air outlet hole 21 is avoided. This reduces the assembly difficulty of the air outlet plate 20 and the frame 10, avoids excessive requirements on assembly precision, and avoids the problem of unusable or poor airflow due to processing errors of the first connecting port 11 and the air outlet hole 21.

[0049] like Figures 1 to 3 As shown, the air outlet holes 21 on the air outlet plate 20 effectively increase the air outlet area. Compared to the traditional method of air outlet from the edge or slit of the air outlet plate 20, the method of setting air outlet holes 21 on the air outlet plate 20 effectively utilizes the space of the air outlet plate 20 and improves the airflow efficiency. Furthermore, the air volume output of the blower can be further increased by reasonably setting the number and arrangement of the air outlet holes 21. Of course, the two methods of edge air outlet of the air outlet plate 20 and air outlet holes 21 on the air outlet plate 20 can be combined to further ensure a large air volume. The hair curling accessory of this application allows the airflow to flow along the preset flow channel, providing a better airflow guiding effect. This airflow path can effectively reduce vibration and wind noise between structural components, improving the user experience; the overall structure is compact, the mechanical strength is stable, and the assembly process is simplified, while strengthening the ability to resist drops and falls, ensuring that the device is more durable.

[0050] To ensure smooth airflow guidance, a reasonable structural design is needed for the positions on the frame 10 and the air outlet plate 20 that guide the gas flow. In particular, the windward surface 22 of the air outlet plate 20 and the air guide surface 12 on the frame 10 need to be properly positioned.

[0051] Specifically, the inner wall of the first connecting opening 11 of the frame 10 also has an air guide surface 12 that connects with the windward surface 22, and the air outlet 21 of the air outlet plate 20 has a windward surface 22 facing the first connecting opening 11, with an included angle B between the air guide surface 12 and the windward surface 22. See the attached reference for details. Figure 5 The aforementioned included angle B creates a flow guide space at the point where the frame 10 contacts the windward surface 22.

[0052] Based on the inventors' numerous experiments, an angle B that is too small cannot effectively guide the airflow; instead, it causes turbulence and generates excessive noise. The embodiments provided in this application set the angle B to be greater than 120 degrees. 120 degrees is a reasonable minimum angle that ensures the airflow receives sufficient guiding force, allowing it to flow smoothly and avoiding turbulence and excessive dispersion.

[0053] Of course, if the included angle B is too large, exceeding 180 degrees, it is also unsuitable. A larger angle will lead to airflow dispersion and expansion, especially when the airflow passes through the air outlet 21. The airflow will be excessively expanded, failing to form an effective guiding effect. This means the airflow is easily and violently dispersed on the outer periphery of the curling attachment, reducing the concentration and stability of the airflow. When the included angle B is too large, the airflow velocity will decrease significantly, and the airflow will begin to lose its original directionality, generating eddies and turbulence, leading to irregular airflow and thus greater noise. In other words, an excessively large included angle will also cause localized airflow interference, increasing unnecessary airflow resistance and noise, affecting the user experience. Furthermore, when the included angle B is greater than 180 degrees, it will cause excessive airflow dispersion, reducing the effective output of airflow. This not only reduces the guiding efficiency of hot or cold air but may also cause the airflow velocity in some areas to be too low, failing to achieve the expected temperature or airflow effect, affecting the curling or other functional effects.

[0054] Therefore, by reasonably controlling the included angle B between 120 degrees and 180 degrees, the airflow will flow stably along the guide surface of the air outlet 21, forming a good airflow path. The included angle within this range can effectively control the direction of the airflow, reduce unnecessary airflow loss, maintain efficient wind power output, and effectively reduce wind noise.

[0055] This allows for effective airflow guidance, reducing airflow loss and noise, and ensuring that both hot and cold air can flow smoothly out of the air outlet 21.

[0056] In addition, by limiting the included angle B to an obtuse angle, a large airflow range is ensured between the frame 10 and the air outlet plate 20. If the included angle B is too small, the air will enter from a narrower inlet, then enter from a wider inlet, and then exit from a narrower outlet, resulting in greater noise. At the same time, the included angle B will not be able to effectively play its role in guiding airflow.

[0057] Experiments have shown that controlling the included angle B between 145 degrees and 155 degrees yields a better flow guiding effect. In this embodiment, the included angle B is preferably 150 degrees.

[0058] Besides constraining angle B, other additional angles can also affect the overall airflow effect of the curling attachment.

[0059] like Figure 7 As shown, the included angle A between the tangent L on the outer peripheral surface of the air outlet plate 20 at the air outlet 21 and the windward side 22 is also crucial.

[0060] Specifically, by limiting the angle A, when the angle A is greater than 120 degrees, the cooperation between multiple air outlets 20 can produce the Coanda effect, causing the hair to be adsorbed onto the outer surface of the curling attachment by the wind generated by the curling attachment.

[0061] Specifically, the air generated by the main body of the device reaches the windward surface 22, moves along the guide of the windward surface 22, and is discharged from the air outlet 21. The discharged air moves along the surface of the air outlet plate 20, causing the hair to curl around the air outlet plate 20. The reasonable setting of the included angle A can ensure the hair adsorption effect, thus making it easier to create a satisfactory style.

[0062] Through repeated verification, a more ideal curly hair effect can be obtained by limiting the included angle A between 145 degrees and 155 degrees. Experiments have shown that the included angle A is not necessarily better the larger it is. When it exceeds a certain range, the overall curvature of the air outlet plate 20 decreases, which is not conducive to curling the hair.

[0063] In other words, by setting the included angle A, the optimal distribution of airflow can be ensured, which not only improves the curling efficiency but also reduces damage to the hair, making it suitable for users who pursue efficient yet gentle curling results.

[0064] In a specific implementation, the included angle A of the multiple air outlets 21 can be different. Alternatively, the included angle A on each air outlet plate 20 can be the same, while the included angle A on adjacent air outlet plates 20 can be different. In other words, the included angle A can be reasonably set according to the different air outlet plates 20; making them all the same angle is also acceptable.

[0065] In one specific embodiment, the included angle A is 150 degrees. Experiments have verified that this angle provides a good Coanda effect, which is beneficial for hair curling. This precise angle design produces the most ideal airflow distribution, suitable for various curling needs, achieving optimal results whether for quick or gentle curls.

[0066] In addition to constraining the included angles A and B, the size and shape of the first connecting port 11, as well as the number, arrangement, and area of ​​the air outlets 21, will also affect the air outlet effect.

[0067] like Figures 2 to 4 As shown, the first connecting port 11 can be clearly seen. The difference from the prior art is that the first air outlet area in the prior art has multiple small connecting holes, while the first connecting port 11 in this application has a larger area, that is, an independent first air outlet area is formed by an independent first connecting port 11.

[0068] exist Figures 2 to 4 In the specific embodiment shown, the first connecting port 11 is preferably rectangular. Of course, a triangular or elliptical first connecting port 11 is also possible. However, a rectangular first connecting port 11 can better utilize the space of the frame 10 and provide sufficient air outlet area.

[0069] However, regardless of how the first connecting port 11 is set, one thing remains constant: all the air outlets 21 on the same air outlet plate 20, when projected onto the frame 10, are located within the periphery of the corresponding first connecting port 11. This means that the overall area of ​​the first connecting port 11 is large enough to cover all the air outlets 21 on the same air outlet plate 20, ensuring that the air delivered from the first connecting port 11 can flow smoothly through the air outlets 21 without being blocked by other structures. Furthermore, the way multiple air outlets 21 are corresponding to the first connecting port 11 allows the air discharged from the first connecting port 11 to quickly pass through the air outlets 21, thereby improving the efficiency of curling.

[0070] Of course, in addition to restricting the shape of the first connecting port 11 and the correspondence between the air outlet 21 and the first connecting port 11, the arrangement of the air outlet plate 20 that cooperates with the frame 10, especially the air outlet 21 on the air outlet plate 20, also affects the air outlet.

[0071] like Figure 6 and Figure 7 As shown, the air outlets 21 are arranged in two staggered rows, making reasonable use of space. Of course, it is also possible to have only one row, in which case the shape and size of the air outlets 21 need to be reasonably set to achieve a good air outlet effect. Moreover, regardless of whether there is one row or multiple rows of air outlets 21, the air outlets 21 do not necessarily have to be arranged in a straight line along the axis of the frame. That is to say, the air outlets 21 can be arranged in various ways on the air outlet plate 20.

[0072] In an embodiment not shown, at least one air outlet 20 has only one air outlet 21, and the air outlet 21 extends along the axial direction of the frame 10. The scheme mentioned here is similar to... Figure 6 Compared to the illustrated solution, instead of multiple air outlets 21 on the same air outlet plate 20, only one air outlet 21 is provided on the air outlet plate 20, and the size of the air outlet 21 is adapted to or slightly smaller than the first connecting port 11. This allows air to be quickly discharged through the first connecting port 11 and the air outlet 21.

[0073] In this specific embodiment, both the first connecting opening 11 and the air outlet 21 are rectangular and of the same size, or the first connecting opening 11 is larger than the opening of the air outlet 21, thereby achieving a large air volume output. This design also generates stronger airflow, making it suitable for scenarios requiring strong styling, such as large curls or curls in stiff hair, ensuring a long-lasting and stable curl effect. When dealing with stiff hair or large curls, this powerful airflow can better overcome the natural shape of the hair, quickly achieving the desired style, making the curls not only aesthetically pleasing but also durable, meeting the hairstyle needs of special occasions.

[0074] Besides the aforementioned solution of setting one air outlet 21, many other solutions involve setting multiple air outlets 21 on the same air outlet plate 20. However, in this application, regardless of the arrangement of the air outlets 21, it is necessary to ensure that each air outlet 21 is covered by its corresponding first connecting port 11.

[0075] by Figure 6 and Figure 7 For example, multiple air outlets 21 on each air outlet plate 20 are spaced apart along the extension direction of the first connecting port 11. In this way, by effectively planning the air outlets 21, multiple air outlets are provided on the air outlet plate 20, which ensures that there is sufficient contact area with the hair and provides sufficient space for the hair to wrap around, thus providing good styling support for the hair.

[0076] by Figure 6 and Figure 7 For example, at least two of the multiple air outlet holes 21 on each air outlet plate 20 are staggered along the circumference of the frame 10. This arrangement forms multiple rows of air outlet holes 21, thereby forming an air outlet group based on rows.

[0077] Of course, it can also be adopted as Figure 6 and Figure 7 The design of the air outlets 21 is as follows: For example, the multiple air outlets 21 on each air outlet plate 20 can be arranged in a straight line, and the straight line is parallel to the axis of the frame 10. That is, multiple rows of air outlets 21 can also be set, but the air outlets 21 are arranged in a very regular matrix, and the number of air outlets 21 in each row of air outlet groups is the same. Of course, it is also possible for the number of air outlets 21 in different rows to be different. The specific design can be based on the actual use requirements.

[0078] In the different embodiments provided above, regardless of whether the multiple air outlets 21 on the air outlet plate 20 are staggered or arranged in a straight line, the air used for styling hair will be discharged from different positions of the air outlet plate 20. The multiple air outlet plates 20 cooperate to make the hair be driven by the wind and thus wrap around the air outlet plate 20. The difference is that the position where the hair is adsorbed on the same air outlet plate 20 is different. When staggered, the hair contacts different positions of the air outlet plate 20, while when the multiple air outlets 21 are arranged in a straight line, the area where the hair is wrapped around the air outlet plate 20 is relatively concentrated.

[0079] Compared to a design with only one air outlet 21 on the same air outlet plate 20, the design of staggered or parallel air outlets 21 can not only create a natural curly effect, but also reduce the pulling on the hair during the curling process and avoid discomfort during the curling process.

[0080] In the specific embodiments provided in this application, any two adjacent air outlets 21 on the air outlet plate 20 are staggered, as shown in the following example. Figures 1 to 3 as well as Figures 5 to 7 As shown, multiple air outlets 21 form two rows on the air outlet plate 20, with the two rows of air outlets 21 staggered.

[0081] In addition to the aforementioned arrangement of the air outlets 21, in an embodiment not shown in this application, the applicant further proposes a technical solution in which multiple air outlets 21 are arranged in a spiral staggered pattern along the circumference of the frame 10. The spiral staggered arrangement of the air outlets 21 allows the airflow to smoothly transition along a curve as it flows through the outlets 21, increasing the airflow distribution range in space. The spiral arrangement also helps the airflow generate a certain rotational effect as it flows along the surface of the air outlet plate 20, further enhancing the airflow's guidance. The spiral flow and uniform distribution of the airflow can better guide the air through the curling attachment, forming a continuous and stable airflow path, which is crucial for the curling effect. Smooth airflow guidance can effectively improve the precision and durability of hair curls, reducing styling instability caused by uneven airflow during the curling process.

[0082] Specifically, multiple air outlets 21 are spaced along the diagonal of the air outlet plate 20 from the bottom to the top. Because the air outlets 21 are arranged diagonally, local pressure concentration is reduced, ensuring a more even distribution of airflow across the entire area. This avoids the uneven airflow or excessive local airflow common in traditional designs, thus improving the overall airflow effect. Optionally, the diagonal direction can be from lower left to upper right or from lower right to upper left; that is, the arrangement of the air outlets 21 can be from lower left to upper right or from lower right to upper left. The advantage of this design is that it allows for adjustment of the airflow output direction according to different usage scenarios or equipment structure requirements, further improving the airflow effect and making the curling effect more stable and lasting. In this technical solution, the multiple air outlets 21 on each air outlet plate 20 are also spaced apart along the extension direction of the first connecting port 11. However, the multiple air outlets 21 on each air outlet plate 20 are arranged in a spiral staggered pattern along the circumference of the frame 10. The spiral staggered arrangement of the air outlets 21 is consistent with the direction of the user's manual rotation of the device when curling hair. This design allows the airflow to flow along a spiral trajectory, forming a positive interaction with the rotation process of curling hair. The airflow forms a natural rotation path during the curling process, helping the hair to be better guided onto the air outlet plate 20, enhancing the layering and curling effect of the curls. The spiral arrangement enhances the combination of airflow and hair, ensuring that the hair receives uniform and continuous airflow during the curling process. This makes the hair more layered when it is wrapped around the air outlet plate, and the hair can be evenly curled under the action of airflow, achieving a more refined and lasting curling effect.

[0083] The spiral staggered arrangement of the air outlets 21 effectively avoids the problem of reduced structural strength caused by an excessive number of air outlets 21 in a certain area of ​​the air outlet plate 20 in traditional designs. Through the distributed spiral arrangement of the air outlets 21, the structural strength is evenly distributed, avoiding localized stress concentration and ensuring the overall mechanical strength and durability of the air outlet plate 20.

[0084] Of course, in addition to giving more consideration to the arrangement of the air outlet 21, this application also gave careful consideration to the connection method between the air outlet plate 20 and the frame 10.

[0085] In this embodiment, the air outlet plate 20 is snapped into the periphery of the first connecting port 11. Snapping the air outlet plate 20 into the first connecting port 11 improves the reliability of the connection between the air outlet plate 20 and the frame 10 and further prevents the air outlet plate 20 from loosening during use.

[0086] Specifically, the frame 10 has multiple grooves 14, and the bottom of each groove 14 has a through hole to form a first connecting opening 11. The diameter of the through hole is smaller than the diameter of the groove 14. When the air outlet plate 20 is installed, the snap-fit ​​side of the air outlet plate 20 snaps into the edge of the groove 14. Optionally, the edge of the groove 14 is provided with a protrusion extending into the groove 14, and the protrusion engages with the snap-fit ​​structure 24.

[0087] In this embodiment, the two opposite sides of the air outlet plate 20 are respectively connected to the edge of the first connecting port 11. The reliability of the connection is ensured by connecting both sides of the air outlet plate 20 to the frame 10. The two longer sides of the air outlet plate 20 are connected to the edge of the first connecting port 11, or all four sides of the air outlet plate 20 are connected to the edge of the first connecting port 11.

[0088] It should be noted here that the two opposite sides of the air outlet panel 20 mentioned above refer to... Figure 2 The two opposite long sides of the air outlet panel 20 are used, although the two opposite short sides of the air outlet panel 20 can also be used. The reason for using two opposite sides of the air outlet panel 20 is that this fixation is relatively firm and more reliable than fixing only two adjacent sides.

[0089] by Figure 2 For example, the air outlet plate 20 is an arc-shaped plate. The two longer sides of the air outlet plate 20 are provided with connecting structures to connect with the frame 10. Of course, connecting structures can also be provided on the two shorter sides of the air outlet plate 20.

[0090] To ensure the reliability of the hair curling accessory, the first side of the air outlet plate 20 is a limiting side with a stop structure 23, and the second side of the air outlet plate 20 is a snap-fit ​​side with a snap-fit ​​structure 24. The stop structure 23 is embedded into the inner side of the first connecting port 11 and cooperates with the edge of the first connecting port 11. The snap-fit ​​structure 24 is engaged with the edge of the first connecting port 11. In other words, the snap-fit ​​method ensures a reliable connection between the air outlet plate 20 and the frame 10 while also providing convenient assembly and disassembly.

[0091] Specifically, the stop structure 23 and the snap-fit ​​structure 24 cooperate with the inner sidewall and outer edge of the first connecting port 11 respectively to achieve the positioning and limiting of the air outlet plate 20, so as to prevent the air outlet plate 20 from shifting and leaking air due to human error or accident when using the air blowing device.

[0092] Furthermore, by setting a stop structure 23 and a snap-fit ​​structure 24 on the first and second opposite sides of the air outlet plate 20 respectively, the air outlet plate 20 is simultaneously subject to two limiting methods by using the stop structure 23 to stop the inner side of the first connecting port 11 and the snap-fit ​​structure 24 to snap-fit ​​the edge of the first connecting port 11, ensuring that the air outlet plate 20 is relatively fixed and difficult to move once installed.

[0093] Additionally, it should be noted that the stop structure 23 is located on the side of the air outlet panel 20 but is not flush with the edge of the air outlet panel 20; rather, it is positioned as follows: Figure 6 The stop structure 23 and the air outlet plate 20 are spaced apart at their edges. When the stop structure 23 abuts against the first connecting port 11, the air guide surface 12 and the windward surface 22 are connected in sequence to form a complete and smooth arc surface. The longer the arc surface, the more obvious the effect of the airflow from the curling attachment flowing along the curve, which can form a more ideal arc trajectory. Finally, the air discharged from the air outlet 21 can produce a better curling effect. Conversely, if the arc surface is too short, the airflow at the windward surface 22 is easy to disperse, which will affect the curling effect.

[0094] like Figures 1 to 3 as well as Figure 5 As shown, since the skeleton 10 is relatively long, it can also be divided into regions. Specifically, according to... Figure 3 For example, the skeleton 10 can be divided into two segments along its axial direction, located in Figure 3 The upper part of the frame 10 has multiple first connecting ports 11. The lower part of the frame 10 can also have multiple second connecting ports 13, each of which independently constitutes a second air outlet area. Alternatively, the first connecting ports 11 can be configured as two sets, one above the other, so that the length of the air outlet plate 20 can be made slightly shorter, avoiding the need for a very long and thin air outlet plate 20.

[0095] exist Figure 3In the illustrated embodiment, to facilitate the installation of the air vent 20, the hair curling accessory also includes a connecting ring 30, which is disposed on the frame 10. The connecting ring 30 is located in the middle of the frame 10. With the connecting ring 30 as the boundary, a first connecting port 11 is opened on the frame 10 and located above the connecting ring 30; a second connecting port 13 (obscured by the air vent 20) is opened on the frame 10 and located below the connecting ring 30. In this case, the second connecting port 13 is axially spaced from the first connecting port 11 on the frame 10.

[0096] In this embodiment, there are multiple first connecting ports 11 and multiple second connecting ports 13. The multiple first connecting ports 11 and multiple second connecting ports 13 are arranged at intervals along the circumference of the skeleton 10. The multiple first connecting ports 11 and multiple second connecting ports 13 can be arranged in a one-to-one correspondence or in an alternating manner.

[0097] In addition, both the frame 10 and the air outlet plate 20 are equipped with structures that are compatible with the connecting ring 30, so that the connecting ring 30 can be snapped onto the outer periphery of the frame 10.

[0098] Furthermore, the air outlet 20 is respectively provided with the first connecting port 11 and the second connecting port 13. The two shorter sides of the air outlet 20 are provided with protruding structures, and the connecting ring 30 is provided with matching slots. The air outlet 20 and the connecting ring 30 are connected and fixed by the protruding structures extending into the slots. When assembling the hair curling accessories, the connecting ring 30 is installed on the frame 10 first, and then the air outlet 20 is installed, which facilitates the installation and fixation of the air outlet 20.

[0099] like Figures 1 to 3 as well as Figure 5 As shown, the hair curling accessory also includes a knob 40 and a connector 50, which are respectively disposed at both ends of the frame 10 for connecting the air outlet plate 20.

[0100] Specifically, the protruding structural part extends into the knob 40, which is located at one end of the frame 10 and connected to multiple air outlet plates 20, thereby limiting the position of the air outlet plates 20 at one end of the frame 10. The connector 50 is located at the other end of the frame 10 and is used to connect to the multiple air outlet plates 20 at that end.

[0101] In addition, the connector 50 is also used to connect with the main body of the equipment, and a vent is provided in the middle of the connector 50. The air generated by the main body of the equipment enters the frame 10 along the vent and passes through the first connecting port 11 and the air outlet 21 or the second connecting port 13 and the air outlet 21 in sequence.

[0102] Of course, as a hair curling accessory, ensuring a favorable curling effect is extremely important. Therefore, the applicant has raised additional considerations for the design of the air outlet plate 20. It should be noted that in this embodiment, the distance L1 between the outer peripheral surface of the air outlet plate 20 and the central axis of the frame 10 is not unique in the circumferential direction of the air outlet plate 20. By setting the outer peripheral surface of the air outlet plate 20 to an irregular arc-shaped surface to form an air outlet gap, the hair is prevented from completely sticking to the outer surface of the air outlet plate 20, reducing uneven heating of the hair. That is, when the hair is completely sticking to the surface of the air outlet plate 20, the airflow will be greatly restricted, and the airflow cannot flow smoothly to every part of the hair. This may result in some areas of the hair being overheated, while other parts do not have enough airflow coverage. This uneven distribution of hot air will lead to unstable curling effect and may even damage the hair.

[0103] Meanwhile, this design can generate dynamic wind pressure distribution. The irregular arc surface can effectively break the direct contact of airflow on the surface of the air outlet, allowing the airflow to generate more flow space around the air outlet, which provides more air circulation space and effectively reduces airflow restriction. This allows hot or cold air to flow quickly and efficiently, helping hair to be better shaped and curled. At the same time, due to this height difference design, wind noise can be effectively reduced, providing users with a relatively quiet user experience.

[0104] In this embodiment, the distance L1 between the outer peripheral surface of the air outlet plate 20 and the central axis of the frame 10 gradually decreases along the middle of the air outlet plate 20 towards the circumferential side edge. In this way, the thickness of the air outlet plate 20 gradually decreases from the middle to both ends, thus creating an air outlet gap between the hair and the outer surface of the air outlet plate 20. Of course, other methods can also be used, such as the distance L1 between the outer peripheral surface of the air outlet plate 20 and the central axis of the frame 10 gradually decreasing along one end of the air outlet plate 20 towards the other end.

[0105] Specifically, such as Figure 8As shown, the distance L1 between the two outer surfaces of the air outlet plate 20 and the frame 10 is different. There is a height difference between the dotted line in the figure and the highest point of the outer surface of the air outlet plate 20. That is to say, there is a height difference between the middle and the two ends of the outer circumference of the air outlet plate 20. Due to the existence of the height difference, the attracted hair is prevented from completely sticking to the air outlet plate 20, causing the air outlet plate 20 to be completely wrapped by the hair, which would prevent smooth airflow and reduce the airflow effect. The existence of the height difference can form an appropriate air outlet gap, allowing the airflow to flow more freely through these gaps, avoiding local airflow blockage, and ensuring that the airflow can be evenly distributed to all parts of the hair, thus making the curling effect more even and stable. This height difference can help the airflow generate a more precise wind force along the path of hair flow, avoiding the phenomenon of excessive airflow concentration or local overheating, thus making the hair curling effect more precise and lasting. With proper guidance, the airflow can better match the shape of the hair to achieve the ideal curling effect.

[0106] Optionally, the height difference is 0.2mm. Too large or too small a height difference is not good. Too small a difference will not achieve the desired effect, while too large a difference will cause a significant change in the shape and will not be conducive to the structural strength of the air outlet plate 20.

[0107] This utility model has at least the following beneficial effects:

[0108] By setting multiple first connecting ports 11 around the frame 10, and multiple air outlet plates 20 corresponding to the multiple first connecting ports 11, each air outlet plate 20 is provided with multiple air outlet holes 21. When the hair curling accessory is used, the air flows from one end of the frame 10 to the other end, then flows through the first connecting ports 11 and is discharged through the multiple air outlet holes 21. Since the multiple air outlet plates 20 are arranged in a circle around the frame 10, the hair is driven by the wind and eventually wrapped around the outer periphery of the hair curling accessory in an orderly manner. Compared with the arrangement of one first connecting port 11 corresponding to one air outlet hole 21, this application can quickly discharge the fluid, improve the efficiency of hair curling, and facilitate the processing and assembly of hair curling accessories. In particular, when the positions of the air outlet holes 21 on each air outlet plate 20 are different, there is no need to limit the installation position of the air outlet plate 20, which greatly improves the assembly efficiency.
