[0034] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.
[0035] In the description of the embodiments of the present disclosure, the term "including" and similar terms should be understood as open inclusion, that is, "including but not limited to." The term "based on" should be understood as "based at least in part 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 previously mentioned, most curling irons require manual assistance when styling hair. This means one hand grasps the ends of the hair while the other hand holds and rotates the iron to wrap the hair around it. Rotating the iron requires turning the wrist, which prevents the iron from maintaining a consistent tilt angle. This can cause uneven winding of the hair around the iron, affecting the styling effect. To address this issue, the presently disclosed embodiments provide a curling iron accessory and a curling iron that automatically absorb hair and evenly wrap it around the iron.
[0037] Figure 1 The following is an exploded view of an exemplary structure of a curling iron attachment 10 according to an embodiment of the present disclosure. The curling iron attachment can cooperate with the handle of the curling iron, and the hair can be automatically adsorbed and wrapped around the cylindrical surface of the attachment without the need to turn the wrist to drive the handle. The hair can be shaped into curls by heating and other methods. The curling iron can provide a variety of different types of attachments to cooperate with the handle. By replacing different attachments, different hair styling needs can be met. Figure 1 As shown, the curling iron accessory 10 includes a barrel 101 and a flow guide 102. The barrel 101 is connected to the handle of the curling iron at one end along its length. Airflow generated within the handle can enter the barrel 101 through an inlet 111 provided at this end. The barrel's sidewall is provided with multiple outlets 112 for airflow to exit. The flow guide 102 includes a first flow-guiding curved surface 121 arranged along the circumference of the barrel 101 and flow guide openings 122 extending toward the barrel's circumference. The openings "opening toward the barrel's circumference" refer to openings extending approximately tangentially to the barrel. That is, when viewed from the barrel's circular cross-section, the openings are closer to the barrel's tangent than to its radial direction. The guide port 122 is provided corresponding to the outlet 112 of the barrel and is opened toward the circumference of the barrel, so that at least a portion of the airflow leaving the barrel through the outlet 112 can be ejected from the guide port 122 closer to the circumference of the barrel, thereby being attracted to the first guide curved surface 121, forming a swirling airflow a flowing around the outer surface of the curling iron attachment 10 (see Figure 4 In this way, the guide port for forming a reflux on the surface of the curling iron attachment is formed on an independent guide member. The guide port structure is not easily affected by other components outside the guide member, making the formed swirling airflow more stable.
[0038] Figure 2A perspective view showing an example structure of a curling iron attachment according to an embodiment of the present disclosure is shown. Figure 2 As shown, in one or more embodiments of the present disclosure, multiple air guides 102 can be evenly arranged around the circumference of the barrel, with the air guide openings 122 of the multiple air guides 102 oriented in the same direction. This facilitates the formation of a continuous and uniform swirling airflow on the outer surface of the curling iron attachment. "In the same direction" means that, when viewed from the circular cross-section of the barrel, the air guide openings of each air guide 102 all face clockwise or counterclockwise. This allows hair to be wrapped around the curling iron attachment more evenly and smoothly.
[0039] Figure 3 Show Figure 2 The cross-sectional view of the midline AA is as follows: Figure 3 As shown, in one or more embodiments of the present disclosure, the air guide member further includes a second curved air guide surface 123 that connects to the first curved air guide surface 121 of an adjacent air guide member. The second curved air guide surface 123 and the first curved air guide surface 121 are located on either side of the air guide opening 122, respectively. This allows the airflow attracted by the first curved air guide surface to flow smoothly from the first curved air guide surface to the adjacent air guide member. This ensures a more continuous and stable swirling airflow around the curling iron attachment, allowing hair to be wrapped more evenly and smoothly around the curling iron attachment. In one or more embodiments of the present disclosure, the second curved air guide surface 123 is higher than the first curved air guide surface 121. In this manner, airflow a flowing on the first curved guide surface of another upstream guide member can flow along the connected second curved guide surface to the surface of the guide member, continue from the second curved guide surface of the guide member to the first curved guide surface of the guide member, and ultimately join airflow a emitted from the guide port onto the first curved guide surface, and together flow to the second curved guide surface of the downstream guide member. This method can increase the intensity of the swirling airflow on the surface of the curling iron attachment, improving the efficiency and effectiveness of hair winding. In one or more embodiments of the present disclosure, the outlet 112 of the barrel connects the hollow air duct within the barrel and the corresponding guide port to provide airflow to the corresponding guide port. In one or more embodiments of the present disclosure, the outlet 112 can gradually narrow along the direction of fluid flow, which can increase the speed of airflow entering the guide port. In one or more embodiments of the present disclosure, the fluid flow path b formed by the outlet 112 gradually tilts toward the corresponding guide port 122 , so that the airflow is more easily adsorbed on the first guide curved surface 121 when emitted from the guide port 122 .
[0040] Figure 4 A perspective view showing an example structure of a barrel of a curling iron attachment according to an embodiment of the present disclosure is shown. Figure 4As shown, in one or more embodiments of the present disclosure, multiple rows of outlets for airflow are evenly distributed along the circumferential sidewall of the barrel 101. Each row of outlets includes multiple outlets 112 evenly spaced along the length of the barrel, facilitating uniform and stable airflow on the outer surface of the curling iron accessory. In one or more embodiments of the present disclosure, each row of outlets is provided with a corresponding air guide, each air guide including a corresponding air guide opening in that row. This arrangement allows the airflow generated on the surface of the curling iron accessory to flow more regularly along the surface of the curling iron accessory. In one or more embodiments of the present disclosure, a first connection portion 113 for attaching and connecting the air guide is provided between two adjacent rows of outlets on the barrel 101. For example, the first connection portion 113 may be a plurality of mounting grooves or mounting openings provided on the sidewall of the barrel 101. In one or more embodiments of the present disclosure, multiple first connection portions 113 may be spaced apart along the length of the barrel to achieve a stable and uniform connection strength. In one or more embodiments of the present disclosure, fourth connection portions 114 may be provided at both ends of the cartridge 101. For example, the fourth connection portions may be a plurality of mounting grooves or mounting openings distributed circumferentially at the ends of the cartridge 101. In one or more embodiments of the present disclosure, one end of the cartridge having a fluid inlet is used to connect to a handle, and the other end is provided with a handle that can be engaged with a positioning cap 104 (see FIG. Figure 2 ) is provided with a positioning cap mounting structure 115 that cooperates with the positioning cap. For example, the positioning cap mounting structure 115 can be a columnar structure that plugs into and mates with the positioning cap. In one or more embodiments of the present disclosure, the positioning cap can include an end portion for plugging into and mates with the positioning cap mounting structure, and also includes a side portion that can cover each fourth connecting portion 114 in the circumferential direction of the barrel. In this manner, the positioning cap 104 can be sleeved onto the end portion of the barrel and protect the connection between the flow guide and the barrel.
[0041] Figure 5 A schematic diagram showing an exemplary structure of the inner side of the guide member of the curling iron attachment according to an embodiment of the present disclosure is shown. Figure 5As shown, in one or more embodiments of the present disclosure, the deflector 102 extends along the length of the barrel and has a second connecting portion 125 on its inner surface that corresponds to the first connecting portion 113. In one or more embodiments of the present disclosure, the second connecting portion 125 can be a plug-in structure provided on the inner surface of the deflector that matches the mounting groove or mounting opening. The deflector and the barrel are positioned by the plug-in fit of the first and second connecting portions. In one or more embodiments of the present disclosure, the inner surface of the sidewall of the deflector 102 facing the barrel is a smooth, curved surface. This allows for smoother and more regular fluid flow within the hollow barrel, reducing turbulent airflow and enabling smoother, less frizzy hair styling. In one or more embodiments of the present disclosure, the deflector can also be provided at both ends with a third connecting portion 126 that mates with the fourth connecting portion 114. The third and fourth connecting portions mate to secure the ends of each deflector to the barrel 101. In one or more embodiments of the present disclosure, the third connecting portion 126 can be a plug-in structure that fits within the recessed fourth connecting portion.
[0042] Figure 6 A cross-sectional view showing an exemplary structure of a guide member of a curling iron attachment according to an embodiment of the present disclosure is shown. Figure 6 As shown, in one or more embodiments of the present disclosure, the first curved guide surface 121 and the second curved guide surface 123 of the guide member are connected by an inclined surface 124, and one or more guide openings 122 are evenly distributed along the length of the guide member on the inclined surface 124. By arranging the guide openings on the inclined surface, the portion of the guide opening for airflow outflow is oriented toward the circumference of the cylinder, while the portion within the guide opening is generally radially disposed to connect with the cylinder outlet. In one or more embodiments of the present disclosure, the guide openings 122 may include an inclined upper top surface 1221 and a lower bottom surface 1222, configured to guide airflow from a radial channel toward the circumferentially disposed outflow portion. The projections of the upper top surface and the lower bottom surface on the circumference of the cylinder may or may not overlap. In one or more embodiments of the present disclosure, the planes of the upper top surface and the lower bottom surface form an angle θ of less than 45°, thereby directing as much airflow as possible to flow along the lower bottom surface 1222 and onto the second curved guide surface that connects to the bottom of the inclined surface 124. In one or more embodiments of the present disclosure, the two ends of the guide member, where the first guide curved surface and the second guide curved surface are located, are respectively provided with a matching connection structure, for example, a step-like structure that matches each other. In this way, adjacent guide members can be spliced together relatively smoothly, reducing airflow obstruction. In one or more embodiments of the present disclosure, the guide member can be an integrally molded part, for example, through injection molding, so that the direction, size and other parameters of the guide port are more consistent and the structure is more stable.
[0043] Figure 7FIG. 2 is a schematic diagram showing an exemplary structure of a curling iron attachment 20 according to another embodiment of the present disclosure. Figure 7 As shown, the guide structure of the curling iron attachment 20 is different in that the guide 202 is not provided with an inclined surface. Figure 8 A cross-sectional view showing an example structure of the flow guide 202 is shown. Figure 8 As shown, in one or more embodiments of the present disclosure, the flow guide 222 is formed on the first flow guide surface 221. In one or more embodiments of the present disclosure, the flow guide 222 may include a side inlet 2221 located on one side of the flow guide. The side inlet 2221 communicates with the outlet of the barrel, allowing fluid flowing out of the outlet to 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 located below the side inlet 2221 and gradually extending upward toward the other side of the flow guide to the edge of the flow guide. For example, the first flow guide wall 2222 may be an outwardly convex curved wall. In this manner, the flow guide is no longer disposed solely on an inclined surface, providing a simpler and more stable flow guide structure. In one or more embodiments of the present disclosure, the second flow guide surface 223 may smoothly connect with the first flow guide surface 221, forming a smoother surface for the curling iron attachment, thereby ensuring more stable and smooth airflow generated by the curling iron. For example, the first guide surface and the second guide surface can be different parts of the same curved surface, and the side inlet 2221 can be located on a side of the guide port near the second guide surface. In this way, the airflow flowing out of the side inlet will flow from the side to the first guide wall, and then flow out of the guide port upward along the first guide wall toward the second guide surface on the other side, making the airflow a formed by the curling iron more stable and smooth. In one or more embodiments of the present disclosure, the second guide surface 223 is provided with a second guide wall 2231 corresponding to the outlet of the barrel, which can guide the airflow flowing out of the outlet of the barrel along the second guide wall into the side inlet 2221. In one or more embodiments of the present disclosure, the second guide wall can be an arc-shaped wall that is concave outward.
[0044] Figure 9 FIG2 shows an exploded view of an exemplary structure of a curling iron attachment 20 according to another embodiment of the present disclosure. Figure 9 As shown, in one or more embodiments of the present disclosure, multiple outlets 212 are provided along the length of the barrel 201. Unlike the barrel 101, some of the outlets of the barrel 201 are provided with first protrusions 213. For example, in one or more embodiments of the present disclosure, a first protrusion may be provided for every other outlet, such that there is one outlet between adjacent first protrusions. A second protrusion 224 is provided on the inner side of the second guide wall of the flow guide member 202 corresponding to the outlet. Figure 10 Shown Figure 7 The cross-sectional view of the center line CC is as follows: Figure 10As shown, during assembly, the second protrusion of the flow guide is inserted into the corresponding outlet of the barrel to position it. In one or more embodiments of the present disclosure, the first protrusion and the second protrusion may have mating surfaces that mate with each other, such that the mating surfaces of the first protrusion and the second protrusion partially overlap. Simultaneously, the mating surface of the second protrusion is provided with a limiting portion 2241 located at the bottom of the first protrusion, thereby limiting the flow guide in the radial direction of the barrel. In one or more embodiments of the present disclosure, a flow guide channel 2242 is provided on the other side of the second protrusion 224, opposite the mating surface. In this way, when the second protrusion is inserted into the outlet of the barrel, the flow guide channel can further concentrate the airflow b and reduce turbulence. In one or more embodiments of the present disclosure, a T-shaped or dovetail-shaped groove can be provided on the circumference of the barrel, and inserts matching the shape of the groove can be provided on both sides of the flow guide. The groove of the flow guide is inserted into the corresponding slot from the end face of the barrel to install the flow guide to the barrel, thereby assembling the cylindrical member.
[0045] While various embodiments of the present disclosure have been described above, the foregoing description is intended to be illustrative, non-exhaustive, and not 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.
