Description

Technical Field

[0001] This utility model relates to the field of nursing appliances, specifically to hair styling accessories and hair styling equipment. Background Technology

[0002] Currently, hair care devices are usually equipped with styling attachments to curl hair. The airflow generated by the styling attachments can be used to adhere the hair to the attachment surface to achieve automatic curling.

[0003] To address this, it is known that the number of air outlets in decorative accessories can be adjusted to improve airflow. However, the number of air outlets is limited by the structural strength requirements of the decorative accessories; too many air outlets can lead to insufficient structural strength.

[0061] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0062] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0063] In the embodiments of this utility model, unless otherwise explicitly stated, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0064] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as referring to relative importance or the number of indicated features. Thus, a feature defined as "first" or "second" may include one or more of that feature.

[0065] As mentioned earlier, hair styling accessories are known to improve airflow by adjusting the number of air outlets. Specifically, since the airflow area of ​​a single air outlet is limited, hair styling accessories are known to increase the overall airflow area by increasing the number of air outlets. However, increasing the number of air outlets can inappropriately weaken the overall structural strength of the styling accessory, thereby affecting the overall stability of the styling accessory during airflow and reducing its lifespan. Therefore, due to the (minimum) structural strength requirements of the styling accessory, it is difficult to increase the overall airflow area by further increasing the number of air outlets.

[0066] In response, this utility model provides a hair styling accessory with an optimized air outlet structure. This air outlet structure increases the air outlet area of ​​a single air outlet through the design of an arc-shaped air outlet, thereby improving the overall air outlet area of ​​the hair styling accessory while ensuring the structural strength of the hair styling accessory, thus enhancing the overall curling effect.

[0067] In some embodiments of this utility model, reference is made to Figures 1 to 6 The hair styling accessory 100 may include a cylindrical body 110. In this embodiment, the cylindrical body 110 surrounds an airflow cavity 111, and one end of the cylindrical body 110 has an airflow inlet 112 communicating with the airflow cavity 111. In some embodiments, the cylindrical body 110 may have a top end 101 and a bottom end 102, wherein the airflow inlet 112 may be disposed at the bottom end 102 to facilitate connection with the device body of the hair styling device and allow airflow from the device body to flow into the airflow cavity 111.

[0068] In some embodiments, reference Figures 1 to 6 The hair styling accessory 100 also includes multiple sets of air outlet unit groups 121 circumferentially spaced on the barrel 110. In some embodiments, each set of air outlet unit groups 121 may include at least one air outlet unit 122. Figure 1 and Figure 3In the illustrated embodiment, each group of air outlet units 121 includes four air outlet units 122. Figure 5 and Figure 6 In the illustrated embodiment, each air outlet unit group 121 includes five air outlet units 122. It is understood that, depending on the specific dimensions of the cylinder 110 and the division of areas, each air outlet unit group 121 may also include more or fewer air outlet units 122, which falls within the protection scope of this utility model.

[0069] In some embodiments, continue to refer to Figures 1 to 6 At least a portion of the air outlet unit group 121 has multiple air outlet units 122 aligned along the axial direction X of the cylinder 110. In some embodiments, the spacing between adjacent air outlet units 122 along the axial direction X is equal. Figures 1 to 5 In the embodiment shown, the multiple air outlet units 122 in the same group of air outlet units 121 are all aligned and arranged along the axial X direction, and the interval between adjacent air outlet units 122 in the axial X direction is equal.

[0070] In some embodiments, each air outlet unit group 121 includes a plurality of first air outlet units and a plurality of second air outlet units. In some embodiments, at least some of the first air outlet units and second air outlet units of the air outlet unit group 121 are staggered in the axial direction X of the cylinder 110. In some embodiments, while the first air outlet units and second air outlet units of the air outlet unit group 121 are staggered in the axial direction X of the cylinder 110, the first air outlet units and second air outlet units may still be aligned in the axial direction X.

[0071] In some embodiments, reference Figure 6 Each air outlet unit group 121 includes multiple first air outlet units and multiple second air outlet units. In some embodiments, at least some of the first and second air outlet units of the air outlet unit group 121 are staggered in both the axial (X) and circumferential directions of the cylinder 110. Figure 6 In the illustrated embodiment, the two first air outlet units and the three second air outlet units are staggered both axially (X) and circumferentially (D1). Through the structure of the above embodiment, a more uniform and comprehensive airflow coverage can be formed on the entire outer surface of the barrel 110, further improving the uniformity and effect of the curling.

[0072] In some embodiments, the first and second air outlet units of the air outlet unit group 121 are completely non-overlapping in both the axial X and circumferential directions of the cylinder 110.

[0073] In some embodiments, in conjunction with reference Figures 3 to 4 The air outlet unit 122 may include an arc-shaped air outlet 123. (Reference) Figure 3The arc-shaped air outlet 123 is arc-shaped on the outer periphery of the cylinder 110. In this embodiment, the arc-shaped air outlet 123 may have a (first) concave arc-shaped air guide edge 124. In the above embodiment, compared with a straight air outlet, such as a straight air outlet extending along the axial direction of the cylinder 110, the arc-shaped air outlet 123 has a longer opening length due to its arc-shaped design, and thus has a larger opening area, i.e., a larger air outlet area. Therefore, the design of the arc-shaped air outlet 123 achieves a balance between air outlet area and structural strength, that is, it provides a larger air outlet area and air volume without increasing the number of air outlets, in other words, without weakening the structural strength of the cylinder 110.

[0074] In some embodiments, in conjunction with reference Figures 1 to 3 Viewed circumferentially from the cylindrical body 110, the arc-shaped air outlet 123 has a non-uniform opening height. In some embodiments, the arc-shaped air outlet 123 may have a middle opening height and end opening heights. In this embodiment, the middle opening height is the opening height of the arc-shaped air outlet 123 at the middle position of its arc-shaped profile, and the second end opening height is the opening height of the arc-shaped air outlet 123 at both ends.

[0075] In some embodiments, the height of the first intermediate opening is greater than the height of the second end opening. Specifically, the arc-shaped air outlet 123 has a larger opening height at the middle of its arc-shaped profile and a smaller opening height at both ends. As an explanation and not a limitation, the opening height of the arc-shaped air outlet 123 varies along different positions of its arc-shaped profile. This non-uniform design can optimize the distribution of airflow, allowing the airflow to have different velocities and flow rates at different locations, thereby guiding the airflow more effectively.

[0076] In some embodiments, in conjunction with reference Figure 2 , Figures 7 to 9 The air outlet unit 122 also includes an air guide slot 127 communicating with the arc-shaped air outlet 123. In some embodiments, the air guide slot 127 is located upstream of the arc-shaped air outlet 123 along the airflow direction. In this embodiment, the air guide slot 127 can pre-guide the airflow before it enters the arc-shaped air outlet 123 from the airflow chamber 111, for example, guiding the airflow as an airflow that is inclined downward along the circumference of the cylinder 110.

[0077] In some embodiments, the arc-shaped air outlet 123 may include two spaced-apart arc-shaped air guide edges 124 in its opening direction D4. In this embodiment, one of the arc-shaped air guide edges 124 (the first arc-shaped air guide edge) may be defined by the downstream edge of the air guide groove 127 along the air guiding direction.

[0078] In some embodiments, reference Figure 3 and Figure 7The air guiding direction D2 of the air guide duct 127 forms an angle with the circumferential direction D1 of the cylinder 110. For example... Figure 7 As shown, a second angle β is formed between the air guiding direction D2 and the circumferential direction D1. In some embodiments, the air guiding direction D2 of the air guide groove 127 is inclined downward relative to the circumferential direction D1 of the cylinder 110. For illustrative purposes, and not as a limitation, the air guiding direction D2 is inclined toward the bottom end 102 of the cylinder 110, thereby guiding the airflow exiting the arc-shaped air outlet 123 to flow obliquely toward the bottom end 102 of the cylinder 110. With the structure of the above embodiments, the air guide groove 127 can help form a spiraling downward airflow around the outer periphery of the cylinder 110, allowing hair of all lengths to be rolled around the cylinder 110 in the direction of the airflow, thereby improving the uniformity and effect of the curl.

[0079] In some embodiments, in conjunction with reference Figure 7 and Figure 8 The air guiding direction D2 of the air guide duct 127 forms an angle with the opening direction D4 of the arc-shaped air outlet. For example... Figure 8 As shown, the air guiding direction D2 of the air guide groove 127 forms a third included angle γ with the opening direction D4.

[0080] In some embodiments, in conjunction with reference Figure 7 and Figure 8 The air guide duct 127 may have a guide bottom surface 1271. In some embodiments, reference is made to... Figure 8 The bottom surface 1271 of the airflow guide is concave in cross-section in the airflow direction D2 perpendicular to the airflow guide groove 127. In this embodiment, the concave bottom surface 1271 can smoothly guide the airflow of the airflow cavity 111 to change direction, preventing the high-speed airflow impacting the airflow guide groove 127 from diverging and generating turbulence in the airflow guide groove 127, thereby improving the concentration and guiding effect of the airflow.

[0081] In some embodiments, the air guide slot 127 has different air guide slot depths in a direction perpendicular to its air guiding direction D2. (See reference) Figure 8 and Figure 9 The depth of the air guide groove 127 at its top (near the top end of the cylinder) is less than its depth at its bottom (near the bottom end of the cylinder). In this embodiment, the air guide groove 127 has a gradually increasing depth from the top to the bottom in a direction perpendicular to its air guiding direction D2. In this embodiment, this depth variation can further optimize the airflow distribution within the air guide groove 127, so that the airflow is naturally guided into an airflow inclined circumferentially to the cylinder 110 by D1.

[0082] In some embodiments, reference Figure 7 and Figure 8 The air guide slot 127 has widened notches 126 at both ends adjacent to the arc-shaped air outlet 123. In some embodiments, reference Figure 8The widened notch 126 can be formed from both sides of the air guide 127 in a direction away from the arc-shaped air outlet 123. By way of explanation and not limitation, this widened notch design can, on the one hand, reduce the airflow resistance at the connection between the air guide 127 and the arc-shaped air outlet 123, making the airflow transition more smoothly from the air guide 127 to the arc-shaped air outlet 123, thereby improving the overall airflow efficiency; on the other hand, it can also help optimize the manufacturing process of the air guide 127 and the arc-shaped air outlet 123, for example, making it easier to demold and reducing the difficulty of the process.

[0083] In some embodiments, continue to refer to Figures 1 to 6 The air outlet unit 122 also includes an air guide surface 125. In some embodiments, the air guide surface 125 is located downstream of the arc-shaped air outlet 123 and extends to the outer surface of the cylinder 110 along the airflow direction. In this embodiment, by means of the air guide surface 125, the air guide surface 125 can further guide the airflow discharged from the arc-shaped air outlet 123. As an explanation and not a limitation, due to the Coanda effect, the airflow discharged through the arc-shaped air outlet (123) will flow along the outer surface of the cylinder 110 under the guidance of the air guide surface (125), thereby automatically drawing in and winding the hair near the hair styling accessory 100 onto the cylinder 110 in the direction of the airflow.

[0084] In some embodiments, as previously described, the arcuate air outlet 123 may include two spaced-apart arcuate air guide edges 124 in its opening direction D4. In this embodiment, one of the arcuate air guide edges 124 (the second arcuate air guide edge) may be defined by the upstream edge of the air guide surface 125 along the air guide direction.

[0085] In some embodiments, reference Figure 4 The air guiding direction D3 of the air guiding surface 125 forms an angle with the circumferential direction D1 of the cylinder 110. For example... Figure 3 As shown, the airflow direction D3 forms a first angle α with respect to the circumferential direction D1, thereby enabling the airflow guide surface 125 to guide the airflow in a predetermined direction. In some embodiments, the airflow direction D3 of the airflow guide surface 125 is inclined downward relative to the circumferential direction D1 of the cylinder 110. For illustrative purposes, and not as limiting, the inclination of the airflow direction D3 toward the bottom end 102 of the cylinder 110 helps guide the airflow exiting the arc-shaped air outlet 123 to form a spiraling downward airflow path. Through the design of the airflow guide surface 125 in the above embodiments, the spiraling downward flow of the airflow can be further enhanced, causing the hair to spirally wrap around the cylinder 110 under the guidance of the airflow, further improving the curling effect.

[0086] In some embodiments, in conjunction with reference Figure 4 , Figure 7 as well as Figure 8The air guiding direction D3 of the air guiding surface 125 is substantially consistent with the air guiding direction D2 of the air guiding groove 127. In some embodiments, the angle between the air guiding direction D3 of the air guiding surface 125 and the air guiding direction D2 of the air guiding groove 127 is within the range of ±10°. For example, the angle can be 0°, ±3°, ±5°, ±8°, or ±10°. By way of explanation and not limitation, by setting the tilt angle and tilt direction of the air guiding direction D3 and the air guiding direction D2 to be substantially the same or close, the air guiding surface 125 and the air guiding groove 127 work together to ensure that the airflow flows in a predetermined direction throughout the entire process from the air guiding groove 127 through the arc-shaped air outlet 123 to the air guiding surface 125.

[0087] In some embodiments, continue to refer to Figure 4 , Figure 7 as well as Figure 8 The opening direction D4 of the arc-shaped air outlet 123 is at an angle to the air guiding direction D3 of the air guiding surface 125 and the air guiding direction D2 of the air guiding groove 127. By way of explanation and not limitation, the opening direction D4 is the direction in which the opening of the arc-shaped air outlet 123 faces, generally towards the radially outer side of the cylinder 110, while the air guiding directions D3 and D2 are configured to be circumferentially inclined downward along the cylinder 110.

[0088] In some embodiments, in conjunction with reference Figure 3 , Figure 4 as well as Figures 7 to 9 The air guide surface 125 is a non-uniform arc-shaped air guide surface.

[0089] In some embodiments, the non-uniform arcuate variation of the air guide surface 125 can be characterized by the (signature) height between the air guide surface 125 and the outer surface of the cylinder 110. In some embodiments, the radial height of the air guide surface 125 relative to the outer surface of the cylinder 110 first increases and then decreases along the axial direction of the cylinder 110.

[0090] In some embodiments, along Figure 3 In the cross-section taken along the centerline BB, there is a first end height H1 between the air guide surface 125 and the outer surface of the cylinder 110; along the Figure 3 In the cross-section taken by the centerline DD, there is a second end height H2 between the air guide surface 125 and the outer surface of the cylinder 110. In this embodiment, the first end height H1 is smaller than the second end height H2. Thus, by means of the height difference formed between the first end height H1 and the second end height H2, the air guide surface 125 can guide the airflow flowing out of the arc-shaped air outlet 123 toward the top 101 away from the cylinder 110, in other words, guide the airflow to flow along the circumference of the cylinder 110 and in a downward inclined direction.

[0091] In some embodiments, reference Figure 8 Along Figure 3In the cross-section taken by the centerline CC, there is a third intermediate height H3 between the air guide surface 125 and the outer surface of the cylinder 110. In this embodiment, the third intermediate height H3 is greater than both the first end height H1 and the second end height H2. In this embodiment, the height difference between the third intermediate height H3 and the first end height H1 is greater than the height difference between the third intermediate height H3 and the second end height H2.

[0092] In some embodiments, the non-uniform arcuate change of the air guide surface 125 can be characterized by the curvature change of the air guide surface 125. In some embodiments, the curvature of the air guide surface 125 first decreases and then increases along the axial direction of the cylinder 110.

[0093] In the above embodiment, this results in a greater curvature change of the air guide surface 125 between the third intermediate height H3 and the first end height H1 than between the third intermediate height H3 and the second end height H2. For illustrative purposes, and not as a limitation, the air guide surface 125 forms a non-uniform airflow path in its middle section by utilizing the height difference and curvature change between the third intermediate height H3, the first end height H1, and the second end height H2, thereby enhancing the guidance of airflow as it flows over the outer surface of the cylinder 110.

[0094] In some embodiments, reference Figure 2 , Figures 13 to 15 The cylinder 110 includes a frame 113 and at least two air outlet plates 120 surrounding the outer periphery of the frame 113. In some embodiments, the frame 113 provides the main structural support for the hair styling accessory 100. In some embodiments, the frame may form an airflow cavity 111. In some embodiments, the cross-section of the airflow cavity 111 is, for example, circular, but it is understood that in other embodiments, the cross-section of the airflow cavity 111 may also be constructed as elliptical or other reasonable shapes. Accordingly, the at least two air outlet plates 120 may be constructed as flat plate structures or curved plate structures. In this embodiment, the cross-sectional shape of the curved plate includes, but is not limited to, circular arcs, elliptical arcs, etc. Those skilled in the art can determine the cross-sectional shape of the curved plate according to actual needs, and this utility model does not limit this.

[0095] In some embodiments, the airflow inlet 112 is located at the bottom end of the frame 113, thereby allowing it to be connected to the device body of the hair styling device via the frame 113.

[0096] In some embodiments, the air outlet plate 120 may be manufactured using integral molding processes including but not limited to injection molding, casting, and die casting. In some embodiments, the air outlet plate 120 may be integrally formed with the air outlet unit 122 thereon, thereby reducing processing steps and lowering process costs. In some embodiments, the air outlet plate 120 may be made of a material with good thermal conductivity, such as a semiconductor thermistor material with a certain degree of temperature sensitivity or other thermally conductive materials. For explanation, when styling hair, the air outlet plate 120 can conduct the heat carried by the airflow to the hair, working in conjunction with the airflow to heat and style the hair, maintaining temperature uniformity during the styling process and improving the hair styling effect.

[0097] In some embodiments, the air outlet plate 120 surrounds the outer periphery of the frame 113, forming the outer surface of the cylinder 110. In some embodiments, each air outlet plate 120 may be provided with at least one set of air outlet unit groups 121. Figure 2 In the illustrated embodiment, each air outlet panel 120 is provided with one set of air outlet unit groups 121. However, it is conceivable that in other embodiments, each air outlet panel 120 may be provided with more sets of air outlet unit groups 121, which falls within the protection scope of this utility model.

[0098] Through the design of the above embodiments, by dividing the cylinder 110 into two parts, the frame 113 and the air outlet plate 120, the manufacturing difficulty can be reduced. For example, the frame 113 can be made of a high-strength material to ensure structural strength; the air outlet plate 120 can be made of a material with good processing performance, which is convenient for processing complex structures such as the arc-shaped air outlet 123, the air guide groove 127, and the air guide surface 125. On the other hand, the segmented air outlet plate 120 can be detachably connected to the frame 113, thereby facilitating maintenance and replacement. When a segment of the air outlet plate 120 is damaged, only that segment of the air outlet plate 120 needs to be replaced, without replacing the entire cylinder 110.

[0099] In some embodiments, in conjunction with reference Figure 2 and Figure 13 The frame 113 has multiple sets of spaced air guide vents 114 along its circumference. In this embodiment, each set of air guide vents 114 may include at least one air guide vent 115. For explanation, the air guide vent 115 is an opening on the frame 113 that connects the airflow cavity 111 to the outside. Airflow from the airflow cavity 111 can be guided through the air guide vent 115 to the air outlet plate 120, for example, to the air guide groove 127 on the air outlet plate 120, and then finally flows to the outer periphery of the cylinder 110 through the arc-shaped air outlet 123 that communicates with the air guide groove 127.

[0100] In some embodiments, one air guide 115 corresponds to at least one arc-shaped air outlet 123. In some embodiments, one air guide 115 may correspond to two, three, or other numbers of arc-shaped air outlets 123. In some embodiments, multiple air guides 115 correspond one-to-one with multiple arc-shaped air outlets 123. (Refer to reference) Figure 2 and Figure 13 Each air guide 115 on the frame 113 is aligned with an arc-shaped air outlet 123 on the air outlet plate 120 in both circumferential and axial positions, thereby ensuring that the airflow can flow smoothly from the air guide 115 to the arc-shaped air outlet 123.

[0101] In some embodiments, in conjunction with reference Figure 2 and Figure 13 At least two air outlet panels 120 are joined end-to-end along the circumference of the cylinder 110 to form a complete annular structure. Figure 2 In the illustrated embodiment, six air outlet panels 120 are arranged around the outer periphery of the frame 113, and the air outlet panels 120 are connected sequentially in the circumferential direction to form a complete annular cylindrical structure. This arrangement can reduce the size and processing difficulty of a single air outlet panel 120 while ensuring the integrity of the cylindrical body 110. However, it is conceivable that more or fewer air outlet panels 120 could be used to surround the outer periphery of the frame 113 to form a complete annular cylindrical structure, which falls within the protection scope of this utility model.

[0102] In some embodiments, in conjunction with reference Figures 7 to 9 The air outlet plate 120 may have a first latching portion 128, and the frame 113 may have a second latching portion 116 that matches the first latching portion 128. The first latching portion 128 and the second latching portion 116 are latched together, thereby realizing a detachable connection between the air outlet plate 120 and the frame 113. In some embodiments, the first latching portion 128 includes a buckle, and the second latching portion includes a slot or hole that engages with the buckle; or the first latching portion 128 is a hole, and the second latching portion 116 is a buckle. In some embodiments, refer to Figures 7 to 15 The first snap-fit ​​part 128 is disposed on the inner surface of the air outlet plate 120 facing the frame 113. When the air outlet plate 120 is installed on the frame 113, the first snap-fit ​​part 128 and the second snap-fit ​​part 116 are hidden inside the cylinder 110. This not only prevents the air outlet plate 120 from accidentally falling off due to user misoperation, but also ensures the simple appearance of the hair styling accessory.

[0103] In some embodiments, reference Figures 7 to 15 When the second latching portion 116 is configured as a slot or a hole, the second latching portion 116 may include various configurations. In some embodiments, reference is made to... Figures 7 to 15The second snap-fit ​​portion 116 is constructed as a slot for the air guide 115 independently disposed on the frame 113. In other embodiments, the second snap-fit ​​portion 116 is partially combined with the air guide 115, that is, the slot structure of the second snap-fit ​​portion 116 is formed by utilizing the air guide 115. This reduces the need for separately constructed structures on the frame 113, simplifying the manufacturing process. On the one hand, it saves structural space of the frame 113; on the other hand, it reduces the manufacturing difficulty and improves manufacturing efficiency.

[0104] In some embodiments, reference Figures 1 to 6 , Figures 13 to 15 The hair styling accessory 100 also includes a connector 117. In some embodiments, the connector 117 may be an annular structure and the outer diameter of the connector 117 may be larger than the outer diameter of the skeleton 113. In this embodiment, the connector 117 may surround the outer periphery of the skeleton 113.

[0105] In some embodiments, the connector 117 and the frame 113 can be detachably installed using a protrusion and groove engagement. In some embodiments, refer to... Figures 13 to 16 The outer peripheral surface of the frame 113 may be provided with a mating groove 118 extending axially, and the connector 117 has a mating protrusion 1171 on its inner side, i.e., the side facing the frame 113, that matches the mating groove 118. In this embodiment, when assembling the connector 117, the mating protrusion 1171 of the connector 117 can be embedded in the mating groove 118, realizing a reliable connection and precise positioning between the connector 117 and the frame 113. As an explanation and not a limitation, the design of the connector 117 can enhance the connection strength between the air outlet plate 120 and the frame 113, and improve the overall structural stability of the hair styling accessory 100.

[0106] In some embodiments, the connector 117 can be used to connect two adjacent air outlet plates 120 in the axial X and circumferential D1 directions, or to position and support the air outlet plates 120 in the axial X direction of the cylinder 110. In some embodiments, reference... Figures 7 to 9 , Figures 13 to 16 The ends of the air outlet plate 120, for example, both ends in the axial direction X, may be provided with at least one first insertion portion 129. Figures 7 to 9 In the illustrated embodiment, each air outlet plate 120 has two first insertion portions 129 at both ends. However, it is understood that more or fewer first insertion portions 129 may be provided in other embodiments, and this utility model does not limit this.

[0107] In some embodiments, the connector 117 may be provided with a second plug-in portion 119 that matches the first plug-in portion 129. In this embodiment, the first plug-in portion 129 can be plugged into the second plug-in portion 119 to achieve a stable installation of the air outlet plate 120 in both the circumferential and radial directions.

[0108] In some embodiments, the connector 117 may be provided with a display area or indicator light to display or prompt the user with information such as the time, styling status, and temperature of hair styling. In some embodiments, the display area may use a small LED display or e-ink screen to display the current styling time and remaining time, allowing the user to intuitively understand the styling progress without having to check the time separately, thereby improving ease of use and user experience.

[0109] In some embodiments, the top end 101 of the cylinder 110 may be provided with an end cap 130, which can be used to close the top opening of the cylinder 110 to prevent airflow from leaking from the top end 101. In some embodiments, the end cap 130 may be connected and fixed to the frame 113 or the air outlet plate 120. The design of the end cap in the above embodiments can further facilitate the user's grip when using the hair styling accessory.

[0110] In some embodiments, a hair styling device is also provided, which may include a device body and a hair styling accessory 100 according to the present invention, wherein the hair styling accessory 100 is configured to be connected to the device body.

[0111] In some embodiments, when using a hair styling device to curl hair, the device generates airflow, which enters the airflow chamber 111 from the airflow inlet 112. The airflow then flows within the airflow chamber 111 and passes through the air guide 115 on the frame 113 before entering the air outlet unit 122 on the air outlet plate 120. Subsequently, within the air outlet unit 122, the airflow first passes through the air guide groove 127, where its direction changes. Specifically, it flows circumferentially and downwards towards the cylinder 110, and is discharged through the arc-shaped air outlet 123. Here, the arc-shaped design of the air outlet 123 provides a larger air outlet area. Finally, the airflow flows along the air guide surface 125, which further guides the airflow to flow along the outer surface of the cylinder 110. In this embodiment, since both the air guide groove 127 and the air guide surface 125 are inclined downwards relative to the circumferential direction of the cylinder 110, the airflow forms a spiral downward flow path throughout the entire flow process. This downward spiral airflow attracts and guides the hair, causing it to curl along the spiral path onto the barrel 110, resulting in uniform curls along the entire length of the barrel 110. Simultaneously, the large air outlet area provided by the arc-shaped air vent 123 ensures sufficient airflow, while the non-uniform arc-shaped air guide surface 125 allows for precise airflow control, ensuring that hair in different locations receives appropriate airflow, thus achieving a high-quality curling effect.

[0112] According to the embodiments of the present invention, the hair styling accessory and hair styling device, by means of the arc-shaped air outlet design, provide a larger air outlet area compared with the straight air outlet, which can significantly increase the air volume of the hair styling accessory without weakening the strength of the cylindrical structure, thereby improving the adsorption effect of the output airflow on the user's hair and improving the user's hair curling experience.

[0113] Furthermore, according to some embodiments of the present invention, the hair styling accessory is provided with an air guide groove that is inclined towards the bottom of the styling accessory upstream of the arc-shaped air outlet. The air guide groove guides the airflow entering the air outlet, thereby outputting a spiral downward airflow from multiple arc-shaped air outlets, so that the hair of the entire length can be effectively wrapped around the styling accessory, thereby further improving the curling effect and user experience.

[0114] Furthermore, according to some embodiments of the present invention, the hair styling accessory and hair styling device are further provided with a downwardly inclined arc-shaped air guide surface downstream of the arc-shaped air outlet, thereby providing a smooth guiding path for the airflow flowing out of the arc-shaped air outlet. At the same time, through the synergistic effect of the arc-shaped air guide surface and the air guide groove, a continuous inclined guide is formed upstream and downstream of the arc-shaped air outlet, ensuring the directionality of the spiral downward airflow and reducing the turbulence disturbance of the downstream airflow, making the output airflow more stable and thus enhancing the airflow's ability to adsorb and curl the hair, further improving the curling effect.
