[0034] Embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings. While some embodiments of this disclosure are shown in the drawings, it should be understood that this disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of this disclosure. It should be understood that the accompanying drawings and embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of protection of this disclosure.

[0035] In the description of embodiments of this disclosure, the term "comprising" and similar terms should be understood as open-ended inclusion, i.e., "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The terms "first", "second", etc., may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0036] As mentioned earlier, most curling irons require manual assistance during styling. One hand needs to hold the ends of the hair, while the other hand holds and rotates the curling iron to wrap the hair around it. Rotating the curling iron requires wrist rotation, which makes it difficult to maintain a consistent angle, resulting in uneven hair wrapping and affecting the styling effect. To address this, this disclosure provides a curling iron attachment and a curling iron that automatically attracts hair and evenly wraps it around the surface of the curling iron.

[0037] Figure 1 An exploded view of an example structure of a curling iron attachment 10 according to an embodiment of the present disclosure is shown. The attachment engages with the handle of the curling iron, automatically attracting and wrapping hair around the cylindrical attachment surface without requiring wrist rotation. Hair is then styled into curls through heating or other methods. The curling iron can provide various types of attachments to engage with the handle; by changing different attachments, different hair styling needs can be met. For example... Figure 1 As shown, the curling iron accessory 10 includes a barrel 101 and a flow guide 102. One end of the barrel 101 is connected to the handle of the curling iron. Airflow generated inside the handle can enter the barrel 101 through an inlet 111 located at this end. Multiple outlets 112 for airflow exit are provided on the side wall of the barrel. The flow guide 102 includes a first flow guide surface 121 arranged circumferentially along the barrel 101 and a flow guide opening 122 opening circumferentially towards the barrel. The "opening circumferentially towards the barrel" means opening in a near-tangential direction of the barrel. That is, viewed from the circular cross-section of the barrel, the opening direction is closer to the tangential direction of the barrel than the radial direction. The airflow inlet 122 is provided corresponding to the outlet 112 of the tube and is opened circumferentially towards the tube, so that at least a portion of the airflow leaving the tube through the outlet 112 can be ejected from the airflow inlet 122 more closely to the circumference of the tube, thereby adsorbing onto the first guide surface 121 and forming a swirling airflow a flowing around the outer surface of the curling iron attachment 10 (see...). Figure 4 In this way, the airflow guide for creating a backflow on the surface of the curling iron attachment is formed on a separate airflow guide. The airflow guide structure is not easily affected by other components outside the airflow guide, making the resulting swirling airflow more stable.

[0038] Figure 2A perspective view of an example structure of a curling iron accessory according to an embodiment of the present disclosure is shown, such as... Figure 2 As shown, in one or more embodiments of this disclosure, multiple air guides 102 can be evenly arranged circumferentially on the barrel, with the air guide openings 122 of the multiple air guides 102 facing the same direction. This facilitates the formation of a continuous and uniform swirling airflow on the outer surface of the curling iron attachment. "Facing the same direction" means that, viewed from the circular cross-section of the barrel, the air guide openings of each air guide 102 face either clockwise or counterclockwise. In this way, hair can be wrapped more evenly and smoothly around the curling iron attachment.

[0039] Figure 3 Show Figure 2 A sectional view of the center section AA, as shown below. Figure 3 As shown, in one or more embodiments of this disclosure, the airflow guide further includes a second airflow guide surface 123 that connects to the first airflow guide surface 121 of an adjacent airflow guide. The second airflow guide surface 123 and the first airflow guide surface 121 are located on opposite sides of the airflow port 122, allowing the airflow adsorbed on the first airflow guide surface to flow smoothly from the first airflow guide surface to another airflow guide adjacent to it. In this way, the swirling airflow of the curling iron attachment becomes more continuous and stable, and the hair can be wrapped more evenly and smoothly around the curling iron attachment. In one or more embodiments of this disclosure, the second airflow guide surface 123 is higher than the first airflow guide surface 121. In this way, the airflow a flowing on the first guide surface of another guide upstream of the guide can flow along the second guide surface connected to it to the surface of the guide, and continue to flow from the second guide surface of the guide to the first guide surface of the guide, finally joining the airflow a emitted onto the first guide surface through the guide port, and flowing together to the second guide surface of another guide downstream of the guide. This method increases the intensity of the swirling airflow on the surface of the curling iron attachment, improving the efficiency and effect of hair winding. In one or more embodiments of this disclosure, the outlet 112 of the barrel connects the hollow air duct inside the barrel and the guide port corresponding to the outlet to provide airflow to the corresponding guide port. In one or more embodiments of this disclosure, the outlet 112 can gradually narrow along the fluid flow direction, increasing the airflow velocity entering the guide port. In one or more embodiments of this disclosure, the fluid flow path b formed by the outlet 112 gradually slopes toward the corresponding guide port 122, making it easier for the airflow to be adsorbed onto the first guide surface 121 when it is emitted from the guide port 122.

[0040] Figure 4 A perspective view shows an example structure of the tube of a curling iron accessory according to an embodiment of the present disclosure, such as... Figure 4As shown, in one or more embodiments of this disclosure, multiple rows of outlet arrays for airflow exit are evenly distributed along the circumferential sidewall of the cylinder 101. Each row of outlets includes multiple outlets 112 evenly arranged along the length of the cylinder, facilitating the formation of a uniform and stable airflow on the outer surface of the curling iron attachment. In one or more embodiments of this disclosure, each row of outlets is provided with a corresponding guide member, and each guide member includes a guide port corresponding one-to-one with each outlet in that row. In this way, the airflow formed on the surface of the curling iron attachment can flow more regularly along the surface of the curling iron attachment in a spiral motion. In one or more embodiments of this disclosure, a first connecting portion 113 for mounting and connecting guide members is provided between two adjacent rows of outlets on the cylinder 101. For example, the first connecting portion 113 can be multiple mounting grooves or mounting ports provided on the sidewall of the cylinder 101. In one or more embodiments of this disclosure, multiple first connecting portions 113 can be arranged at intervals along the length of the cylinder to obtain a stable and uniform connection strength. In one or more embodiments of this disclosure, a fourth connecting portion 114 may be provided at both ends of the cylinder 101. For example, the fourth connecting portion may be a plurality of mounting grooves or mounting ports distributed circumferentially at the ends of the cylinder 101. In one or more embodiments of this disclosure, one end of the cylinder with a fluid inlet is used to connect a handle, and the other end is provided with a positioning cap 104 (see...) Figure 2 The positioning cap mounting structure 115 is designed to cooperate with the positioning cap. For example, the positioning cap mounting structure 115 may be a columnar structure that is inserted into the positioning cap. In one or more embodiments of this disclosure, the positioning cap may include an end portion for inserting into the positioning cap mounting structure, and may also include a side portion that can cover each of the fourth connecting portions 114 in the circumferential direction of the cylinder. In this way, the positioning cap 104 can be fitted onto the end of the cylinder and protect the connection position between the guide and the cylinder.

[0041] Figure 5 A schematic diagram of an example structure of the inner side of the guide of a curling iron accessory according to an embodiment of the present disclosure is shown, such as... Figure 5As shown, in one or more embodiments of this disclosure, the guide member 102 extends along the length of the cylinder, and its inner surface is provided with a second connecting portion 125 corresponding to the first connecting portion 113. In one or more embodiments of this disclosure, the second connecting portion 125 may be an insertion structure provided on the inner surface of the guide member that matches the mounting groove or mounting port, and the guide member and the cylinder are positioned by the insertion and engagement of the first connecting portion and the second connecting portion. In one or more embodiments of this disclosure, the inner surface of the guide member 102 facing the side wall of the cylinder is a smooth arc surface. In this way, the fluid flow inside the hollow cylinder can be smoother and more regular, reducing turbulent airflow and making hair styling smoother and less frizzy. In one or more embodiments of this disclosure, the two ends of the guide member may also be provided with a third connecting portion 126 for engaging with the fourth connecting portion 114. Through the engagement of the third connecting portion and the fourth connecting portion, the ends of each guide member can be fixed to the cylinder 101. In one or more embodiments of this disclosure, the third connecting portion 126 may be an insert structure installed in the recessed fourth connecting portion.

[0042] Figure 6 A cross-sectional view of an example structure of a guide for a curling iron accessory according to an embodiment of the present disclosure is shown, such as... Figure 6 As shown, in one or more embodiments of this disclosure, the first guide surface 121 and the second guide surface 123 of the guide member are connected by an inclined surface 124, and one or more guide ports 122 are uniformly disposed on the inclined surface 124 along the length direction of the guide member. By disposing the guide ports on the inclined surface, the portion of the guide port from which the airflow exits is opened toward the circumference of the cylinder, while the portion inside the guide port is opened approximately along the radial direction of the cylinder in order to communicate with the outlet of the cylinder. In one or more embodiments of this disclosure, the guide port 122 may include an inclined upper top surface 1221 and a lower bottom surface 1222 for guiding the airflow from the radial channel toward the circumferentially disposed outflow portion. The projections of the upper top surface and the lower bottom surface in the circumferential direction of the cylinder may overlap or not overlap. In one or more embodiments of this disclosure, the planes containing the upper top surface and the lower bottom surface form an angle θ of less than 45°, which can guide as much airflow as possible to flow out along the lower bottom surface 1222 and to the second guide surface that connects with the bottom of the inclined surface 124. In one or more embodiments of this disclosure, the two ends of the first and second guide surfaces of the flow guide are respectively provided with mating connection structures, such as mating stepped structures. This allows adjacent flow guides to be smoothly joined together, reducing airflow obstruction. In one or more embodiments of this disclosure, the flow guide can be a one-piece molded part, for example, through injection molding, resulting in better consistency in parameters such as the direction and size of the flow outlet, and a more stable structure.

[0043] Figure 7A schematic diagram of an example structure of a curling iron accessory 20 according to another embodiment of the present disclosure is shown. Figure 7 As shown, the difference in the guide structure of the curling iron attachment 20 is that the guide 202 does not have an inclined surface. Figure 8 A cross-sectional view of an example structure of the flow guide 202 is shown, as follows: Figure 8 As shown, in one or more embodiments of this disclosure, the flow guide 222 is formed on the first flow guide surface 221. In one or more embodiments of this disclosure, the flow guide 222 may include a side inlet 2221 disposed on one side of the flow guide, the side inlet 2221 communicating with the outlet of the cylinder, so that fluid flowing out of the outlet can enter the flow guide 222 from the side through the side inlet 2221. The flow guide 222 may also include a first flow guide wall 2222, the first flow guide wall 2222 disposed below the side inlet 2221 and gradually extending upward toward the edge of the flow guide to the other side of the flow guide. For example, the first flow guide wall may be an outwardly convex arc-shaped wall. In this way, the flow guide is no longer separately disposed on the inclined surface, which can provide a simpler and more stable flow guide structure. In one or more embodiments of this disclosure, the second flow guide surface 223 can be smoothly connected to the first flow guide surface 221, which can form a smoother surface of the curling iron accessory, making the airflow formed by the curling iron more stable and smooth. For example, the first and second guide surfaces can be different parts of the same arc surface, and the side inlet 2221 can be located inside the guide opening near the second guide surface. In this way, the airflow exiting through the side inlet will flow from the side to the first guide wall, and then flow upward along the first guide wall towards the second guide surface on the other side, exiting the guide opening, making the airflow a formed by the curling iron more stable and smooth. In one or more embodiments of this disclosure, the second guide surface 223 is provided with a second guide wall 2231 corresponding to the outlet of the tube, which can guide the airflow exiting through the outlet of the tube to enter the side inlet 2221 along the second guide wall. In one or more embodiments of this disclosure, the second guide wall can be an outwardly concave arc-shaped wall.

[0044] Figure 9 An exploded view of an example structure of a curling iron accessory 20 according to another embodiment of the present disclosure is shown. Figure 9 As shown, in one or more embodiments of this disclosure, a plurality of outlets 212 are provided along the length of the cylinder 201. Unlike the cylinder 101, some outlets of the cylinder 201 are provided with first protrusions 213. For example, in one or more embodiments of this disclosure, a first protrusion may be provided every other outlet, such that an outlet is spaced apart between adjacent first protrusions. A second protrusion 224 is provided on the inner side of the second guide wall of the flow guide 202 corresponding to the outlet. Figure 10 It shows Figure 7 A sectional view of the center section CC, as shown below. Figure 10As shown, during assembly, the second protrusion of the guide member is inserted into the corresponding outlet of the cylinder for positioning. In one or more embodiments of this disclosure, the first and second protrusions may have mating surfaces that partially overlap. Simultaneously, the mating surface of the second protrusion has a limiting portion 2241 located at the bottom of the first protrusion, thereby limiting the guide member in the radial direction of the cylinder. In one or more embodiments of this disclosure, a guide channel 2242 is provided on the opposite side of the second protrusion 224 from the mating surface. In this way, when the second protrusion is inserted into the outlet of the cylinder, the guide channel can concentrate the airflow b, reducing turbulence. In one or more embodiments of this disclosure, a T-shaped or dovetail-shaped groove can be provided circumferentially on the cylinder, and inserts matching the shape of the groove can be provided on both sides of the guide member. By inserting the groove of the guide member into the corresponding slot from the end face of the cylinder, the guide member can be installed onto the cylinder and assembled into a cylindrical component.

[0045] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or technical improvements to the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
