Description

Technical Field

[0001] The embodiments of the present disclosure generally relate to the field of hairdressing appliances, and in particular to a dispensing ring, a curling iron attachment, and a curling iron. Background Art

[0002] Most curling irons require manual winding during styling. This means you need to grasp the ends of your hair with one hand while holding and rotating the iron with the other hand to wrap your hair around it. This requires you to twist your wrist while rotating the iron, which can cause the iron to tilt at an inconsistent angle, resulting in uneven winding of the hair and affecting the styling effect. This is especially true for those with thinning hair or those who have had their hair cut or styled in layers. Insufficient winding force can cause hair to slip, compromising the styling effect. Summary of the Invention

[0003] Embodiments of the present disclosure provide a dispensing ring, a curling iron attachment, and a curling iron that are intended to address one or more of the above-mentioned problems and other potential problems.

[0004] According to a first aspect of the present disclosure, a curling iron accessory is provided, comprising a cylindrical member, including an inlet for airflow inlet and a guide port for airflow outflow, wherein at least a portion of the airflow emitted through the guide port flows around an outer surface of the cylindrical member. Furthermore, the curling iron accessory further comprises a distribution ring disposed on the outer surface of the cylindrical member to divide the outer surface of the cylindrical member into a plurality of styling zones along the length of the cylindrical member.

[0005] According to a second aspect of the present disclosure, a dispensing ring is provided for being fitted over the outer surface of a cylindrical member to divide the outer surface of the cylindrical member into a plurality of shaping zones along the length of the cylindrical member. The dispensing ring includes an annular body and a non-slip inner ring disposed within the annular body. The dispensing ring is connected to the cylindrical member via the non-slip inner ring.

[0006] According to a third aspect of the present disclosure, a curling iron is provided, comprising the curling iron accessory described in the first aspect.

[0024] 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.

[0025] 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.

[0026] As mentioned above, most curling irons require manual assistance for curling during styling, that is, one hand needs to grasp the end of the hair, and the other hand holds and rotates the curling iron to wrap the hair around the curling iron. When rotating the curling iron, the wrist needs to be turned, and the tilt angle of the curling iron cannot be kept consistent, which will cause the hair to be unevenly wrapped around the curling iron, affecting the styling effect of the curling iron. For users with sparse hair or high-level hair styling, the hair is prone to slippage due to insufficient winding force, resulting in uneven contact area between the hair bundle and the heating surface, causing the curling iron's heat energy transfer efficiency to decrease and unbalanced heating of the hair bundle. This contact instability will directly cause local hair bundles to be heated for insufficient time, ultimately resulting in defects such as weak curl retention and poor styling durability.

[0027] Figure 1 The following is a schematic diagram showing an example structure of a curling iron attachment according to an embodiment of the present disclosure. The curling iron attachment can cooperate with the handle of the curling iron to heat the hair wrapped around the surface of the curling iron attachment, thereby shaping the hair into curls. 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 1 includes a cylindrical member 10 and one or more distribution rings 20. The cylindrical member includes an inlet 111 for airflow entry and a guide port 122 for directing airflow exit. At least a portion of the airflow exiting the guide port 122 of the cylindrical member can flow around the outer surface of the cylindrical member. The cylindrical member can be constructed in any manner capable of forming a swirling airflow that is absorbed by the surface of the curling iron, thereby automatically wrapping hair around the outer surface of the curling iron without requiring wrist movement. In one or more embodiments of the present disclosure, the distribution ring is sleeved on the outer surface of the cylindrical member, thereby dividing the outer surface of the cylindrical member into multiple styling zones along the length of the cylindrical member.

[0028] In this way, the physical barrier of the distribution ring can ensure that the hair is only curled in the area between two adjacent rings, or in the area on one side of a single ring, preventing the hair from sliding or dispersing between different areas, forming more regular and concentrated curls. In addition, the physical barrier of the distribution ring can prevent the hair from sliding out of the curling iron due to gravity or improper operation during the heating and styling process, thereby ensuring that the hair stays on the surface of the curling iron for a sufficient time, is evenly and fully heated, and has a better and more stable styling effect.

[0029] In one or more embodiments of the present disclosure, the dispensing rings can be removably mounted on the outer surface of the cylindrical member, allowing different numbers of dispensing rings to be selected based on different styling requirements (e.g., hair length and volume). In one or more embodiments of the present disclosure, the dispensing rings can be movably mounted on the outer surface of the cylindrical member, allowing the spacing between the dispensing rings to be adjusted to suit different styling needs. A smaller spacing creates a narrower styling area, compressing the hair into a smaller space and thus forming tighter, more detailed curls. A larger spacing creates a wider styling area, allowing the hair to curl over a wider area, resulting in more open, natural waves. Therefore, by adjusting the spacing between the dispensing rings, the tightness and curvature of the curls can be flexibly controlled to meet the needs of different hair types (e.g., fine hair requires a tight curl, while coarse hair requires a loose curl).

[0030] Figure 2 A schematic diagram showing an example structure of a distribution ring according to an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the distribution ring 20 may include an annular body 201 and an anti-slip inner ring 202 provided inside the annular body. The distribution ring 20 is connected to the cylindrical member 10 via the anti-slip inner ring 202, so that it can be sleeved outside the cylindrical member, and can also move on the surface of the cylindrical member and come out from the top of the cylindrical member. In one or more embodiments of the present disclosure, the anti-slip inner ring may be made of a material such as silicone, that is, it can provide appropriate deformation to fit the outer surface of the cylindrical member, and fix the distribution ring by the friction between the two. When the position of the distribution ring on the cylindrical member needs to be adjusted or the distribution ring needs to be removed from the cylindrical member, the distribution ring can be moved by dragging the distribution ring. In one or more embodiments of the present disclosure, the anti-slip inner ring may also be made of a material such as plastic, and the inner diameter of the distribution ring can be changed by changing the shape, size and structure of the anti-slip inner ring, thereby achieving movement or fixation of the distribution ring on the surface of the cylindrical member. In one or more embodiments of the present disclosure, the annular body is positioned outside the anti-slip inner ring. This protects the inner ring and can be designed to a specific height or width to accommodate zoning requirements on the cylindrical surface. Furthermore, the annular body reduces heat transfer, concentrating it within the molding area between adjacent distribution rings, preventing burns and improving molding efficiency.

[0031] Figure 3 A cross-sectional view showing an exemplary structure of a dispensing ring in a fixed state and a movable state according to an embodiment of the present disclosure is shown. Figure 3 As shown, in one or more embodiments of the present disclosure, the anti-slip inner ring 202 can be provided with at least one adjustment opening 221, and the anti-slip inner ring is mounted on the inner surface of the annular body 201 via a first elastic member 203. Therefore, the anti-slip inner ring 202 can move radially along the distribution ring. The first elastic member connecting the anti-slip inner ring and the annular body is in a compressed state and can apply an elastic force inward (i.e., toward the center of the annular body) to the anti-slip inner ring. In one or more embodiments of the present disclosure, the size of the adjustment opening can vary with the position of the anti-slip inner ring. Inside the annular body, the closer the position is to the center of the circle, the smaller the radius of the corresponding annular structure. When the anti-slip inner ring is near the center of the circle, the adjustment opening of the anti-slip inner ring is also smaller, and the radius of the anti-slip inner ring (i.e., the inner diameter of the anti-slip inner ring) is smaller, thereby ensuring that the distribution ring hoop is on the outer surface of the cylindrical member. When the anti-slip inner ring is positioned away from the center of the circle, the adjustment opening of the anti-slip inner ring is also larger, and the radius of the anti-slip inner ring (i.e., the inner diameter of the anti-slip inner ring) is larger, allowing the dispensing ring to move on the outer surface of the cylindrical member or be removed from the cylindrical member. In one or more embodiments of the present disclosure, the first elastic member can be a structure such as a spring, rubber, a spring, a thermoplastic elastomer, or a thermosetting elastomer. The elastic force exerted by the first elastic member can cause the anti-slip inner ring to move inward, maintaining its position of tightening the cylindrical member. In one or more embodiments of the present disclosure, a control member 222 can be provided in the adjustment opening 221. The width w of the control member 222 gradually decreases along the radial direction of the dispensing ring toward the inside of the dispensing ring (i.e., toward the center of the dispensing ring). The control member 222 can be mounted to the outer surface of the annular body 201 via the second elastic member 204. Therefore, the control member 222 can move radially along the dispensing ring. In one or more embodiments of the present disclosure, the second elastic member can be a structure such as a spring, rubber, a spring, a thermoplastic elastomer, or a thermosetting elastomer. The second elastic member 204 connecting the control member and the annular body is in a stretched state, capable of applying an outward elastic force to the control member (i.e., away from the center of the annular body). In one or more embodiments of the present disclosure, the control member can have a fan-shaped profile in the cross-section of the dispensing ring. Under the action of the second elastic member, the control member tends to move outward, causing the relatively inward portion of the control member (i.e., the narrower portion of the control member) to be positioned within the adjustment opening of the anti-slip inner ring. When the control member is subjected to an inward force, it moves radially inward along the dispensing ring, causing the relatively outward, wider portion of the control member to move into the adjustment opening, expanding it. This pushes the anti-slip inner rings on both sides to move away from the center of the dispensing ring to a larger radius, thereby allowing the dispensing ring to move along the outer surface of the cylindrical member or be removed from the cylindrical member.

[0032] Figure 4 A schematic diagram showing an example structure of a ring-shaped body of a distribution ring according to an embodiment of the present disclosure is shown as follows: Figure 4 As shown, in one or more embodiments of the present disclosure, the annular body 201 may include an annular base 211, an annular sidewall 212, and a mounting seat 213 disposed on the annular base. The annular base may be an annular plate, and the annular sidewall may be a vertical plate disposed on the outer periphery of the annular base. In one or more embodiments of the present disclosure, a plurality of springs may be evenly distributed on the inner surface of the annular sidewall, one end of the spring being connected to the annular sidewall and the other end being connected to the outer surface of the anti-slip inner ring, so that the anti-slip inner ring is movably mounted on the annular body. A mounting opening 2121 is provided at a position on the annular sidewall corresponding to the adjustment opening of the anti-slip inner ring and is in communication with the adjustment opening. In one or more embodiments of the present disclosure, the mounting opening may be an opening wider than the adjustment opening, and a mounting seat 213 for mounting a control member may be provided in the mounting opening. One or more springs may be provided on the outer surface of the mounting seat, one end of the spring being connected to the mounting seat and the other end being connected to the control member, so that the control member can move within the adjustment opening corresponding to the mounting opening.

[0033] Figure 5 A schematic diagram showing an example structure of a ring-shaped body and a control member of a distribution ring according to an embodiment of the present disclosure is shown as follows: Figure 5As shown, in one or more embodiments of the present disclosure, the control member 222 may include an operating portion 2221 for connecting to the second elastic member and plug-in legs 2222 located at both ends of the operating portion. In one or more embodiments of the present disclosure, the operating portion may be a plate-like structure in the shape of an arc, and the outer diameter of the arc-shaped structure is approximately the same as the outer diameter of the annular side wall, so that the operating portion can be spliced ​​with the annular side walls on both sides into a roughly complete circular ring. In one or more embodiments of the present disclosure, the mounting seat may be a structure with high sides and low middle, located in the middle of the mounting opening, with gaps 214 on both sides. The middle recessed portion of the mounting seat is used to install a spring facing the outside of the annular body, and the control member 222 can be connected by a spring and sleeved on the outside of the mounting seat, and the plug-in legs 2222 of the control member are inserted into the gap 214 between the mounting seat and the annular side walls on both sides, and move in the gap. In this way, the mounting seat can provide support for the control member and improve the structural strength. In order to prevent the control member from detaching from the adjustment port, in one or more embodiments of the present disclosure, a first limiting structure 2223 may be provided at the end of the plug-in leg 2222, and a second limiting structure 215 provided toward the gap may be provided on the mounting seat or the anti-slip inner ring. For example, a transverse plate-like structure is provided at the end of the plug-in leg 2223 as the first limiting structure, and correspondingly, protrusions facing the gap on both sides of the mounting seat are provided as the second limiting structure, and the anti-slip inner ring is also provided with a protrusion facing the gap as the second limiting structure. In this way, the second limiting structures of the mounting seat and the anti-slip inner ring form a narrowed opening at the gap, which is smaller than the first limiting structure at the end of the plug-in leg, thereby preventing the control member from detaching from the gap during movement, thereby achieving radial limiting of the control member.

[0034] In one or more embodiments of the present disclosure, the anti-slip inner ring can be made of a material with a certain degree of deformation ability, such as silicone or shape-memory hydrogel, and the adjustment port can be a hole-like structure opened on the side surface of the anti-slip inner ring. In one or more embodiments of the present disclosure, the anti-slip inner ring can also be made of a relatively hard plastic material, and the fracture structure formed on the anti-slip inner ring, that is, the anti-slip inner ring can be composed of several split parts, and the gaps between adjacent parts serve as the adjustment port. Figure 6 A schematic diagram showing an assembly of an exemplary structure of a distribution ring according to an embodiment of the present disclosure is shown in FIG. Figure 6As shown, in one or more embodiments of the present disclosure, the anti-slip inner ring 202 may include two relatively arranged arc-shaped parts 223, and two relatively arranged adjustment ports 221 are formed between adjacent arc-shaped parts. The control part 222 installed in the adjustment port and the arc-shaped part 223 can be spliced ​​into a roughly complete annular structure. Correspondingly, the annular side wall 212 may also include two relatively arranged arc-shaped side walls 2121, and the arc-shaped side walls correspond to the arc-shaped parts one by one. Each arc-shaped side wall is used to install a corresponding arc-shaped part, and two relatively arranged installation ports are formed between adjacent arc-shaped side walls. The arc-shaped side walls 2121 and the operating part 2221 of the control part can be spliced ​​into a roughly complete annular structure. In this way, the entire distribution ring can present a nearly annular structure, which is convenient for users to hold and operate. When adjusting the position of the distribution ring, the thumb and index finger of one hand can be used to pinch the control parts at both ends of the distribution ring respectively, to expand the anti-slip inner ring, so that the inner diameter of the distribution ring becomes larger, so that the distribution ring can be pulled to the desired position, and then release the hand. The anti-slip inner ring shrinks under the elastic force of the first elastic part, and the inner diameter of the distribution ring becomes smaller, and it is tightened to the outer surface of the cylindrical part.

[0035] In one or more embodiments of the present disclosure, the annular body may further include an annular top cover 216 disposed opposite the annular base 211, with the annular sidewall and the mounting seat located between the annular top cover and the annular base. The annular top cover 216 may have the same structure as the annular base. By sealing the distribution ring with the annular top cover and the annular base, the internal movement structure of the distribution ring can be protected, hair can be prevented from being drawn into the distribution ring, and heat transfer within the distribution ring can be reduced. In one or more embodiments of the present disclosure, the annular sidewall and the mounting seat may be made of a plastic material integrally molded with the annular base, and the annular top cover may also be assembled together using the same material via the mounting seat. Figure 7 A cross-sectional view showing an exemplary structure of a distribution ring according to an embodiment of the present disclosure at another viewing angle is shown. Figure 7 As shown, for example, in one or more embodiments of the present disclosure, the raised portions at both ends of the mounting base can be configured as hollow structures, with openings at the end faces of the mounting base forming insertion ports 2131 extending axially along the dispensing ring 20. Furthermore, a plug-in strip 2161 cooperating with the insertion port 2131 can be provided on the annular top cover 216. The plug-in strip can be inserted into the insertion port to connect the annular top cover to the mounting base. This facilitates assembly and disassembly of the dispensing ring.

[0036] Figure 8 A schematic diagram showing an example structure of another distribution ring according to an embodiment of the present disclosure. Figure 8As shown, in one or more embodiments of the present disclosure, the distribution ring 30 may include an annular body 301 and an anti-slip inner ring provided on the inner surface of the annular body. The distribution ring 30 is connected to the cylindrical member through the anti-slip inner ring, so that it can be mounted outside the cylindrical member, and can also move on the surface of the cylindrical member and fall out from the top of the cylindrical member. In one or more embodiments of the present disclosure, the anti-slip inner ring 302 is made of a flexible material such as silicone, that is, it can provide appropriate deformation to fit the outer surface of the cylindrical member, and the distribution ring is fixed by the friction between the two. When the position of the distribution ring on the cylindrical member needs to be adjusted or the distribution ring needs to be removed from the cylindrical member, the distribution ring can be moved by dragging the distribution ring. In one or more embodiments of the present disclosure, the annular body 301 can be made of plastic material and be spliced ​​by two plastic half rings. The anti-slip inner ring may include an upper anti-slip strip 3021 located on the upper portion of the inner surface of the annular body 301, a lower anti-slip strip 3022 located on the lower portion of the inner surface of the annular body 301, and a mounting surface 3023 located between the upper and lower anti-slip strips, connecting the upper and lower anti-slip strips 3021 and 3022. The upper and lower anti-slip strips protrude toward the center of the dispensing ring relative to the mounting surface and contact the outer surface of the cylindrical member. Because the upper and lower anti-slip strips protrude relative to the mounting surface, the dispensing ring only partially contacts the cylindrical member through the position of the upper and lower anti-slip strips. This provides friction that secures the dispensing ring to the cylindrical member and facilitates the application of external force to move or remove the dispensing ring. In one or more embodiments of the present disclosure, a matching structure for connecting to the annular body is provided on the side of the mounting surface 3023 facing the annular body. For example, a mounting hole for fixing the anti-slip inner ring can be provided on the side of the annular body. The matching structure can be a protrusion corresponding to the mounting hole, and the protrusion can be inserted into the mounting hole to fix the anti-slip inner ring to the annular body. In one or more embodiments of the present disclosure, the distribution ring 30 can also include two half rings provided outside the annular body, and the two half rings are spliced ​​together by a splicing structure provided on the docking surface. The side of the annular body 301 is also provided with a limiting groove for installing the half rings, and the two half rings are fixed to the outside of the annular body by a corresponding snap-fit ​​structure. In this way, the two half rings can protect the internal annular body structure on the one hand, and can also cover the surface of the annular body as a heat insulating portion on the other hand, so that the heat is concentrated in the styling area between adjacent distribution rings, avoiding perming and dyeing while improving styling efficiency.

[0037] Figure 9 Schematic diagram showing an example structure of a cylindrical member 10 according to an embodiment of the present disclosure. Figure 9As shown, in one or more embodiments of the present disclosure, the tubular member 10 may include a barrel 101 and a flow guide 102. The barrel 101 is connected to the handle of the curling iron at one end in the longitudinal direction. The airflow formed inside the handle can enter the barrel 101 through an inlet 111 provided at this end. A plurality of outlets 112 for the airflow to leave are provided on the side wall of the barrel. The flow guide 102 includes a first flow guide curved surface 121 provided along the circumference of the barrel 101 and a flow guide port 122 opened toward the circumference of the barrel. The port "opened toward the circumference of the barrel" refers to a port opened in a near tangential direction of the barrel. That is, when observed from the circular cross-section of the barrel, the opening direction of the port is closer to the tangential direction of the barrel than to the radial direction of the barrel. 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 (see Figure 10 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] In one or more embodiments of the present disclosure, a plurality of flow guides 102 can be evenly arranged around the circumference of the barrel 101, and the flow guide openings 122 of the plurality of flow guides 102 are oriented in the same direction. This facilitates the formation of a continuous and uniform swirling airflow on the outer surface of the curling iron accessory. "In the same direction" means that, when observed from the circular cross-section of the barrel, the flow guide openings of each flow guide 102 are all oriented in a clockwise direction, or in a counterclockwise direction. In this way, the user only needs to place the hair in the guide area where the constraint is located, and the adsorption airflow generated by the tubular member can automatically adsorb and curl the hair, which is especially suitable for users with long hair or a lot of hair. For coarse hair or hair that easily tangles, the adsorption airflow generated by the tubular member can reduce the resistance of the hair entangled in the constraint, thereby improving efficiency. At the same time, the airflow and temperature can be adjusted by the constraint to reduce damage to the hair.

[0039] 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, a flow guide 102 is provided for each row of outlets, each flow guide including a flow guide opening corresponding to each outlet in that row. This arrangement allows the airflow formed 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 flow guide is provided between adjacent rows of outlets on the barrel 101. For example, the first connection portion 113 may be a plurality of mounting slots or 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 provided at intervals along the length of the barrel to achieve a stable and uniform connection strength. In one or more embodiments of the present disclosure, a fourth connecting portion 114 may also be provided at both ends of the tube 101. For example, the fourth connecting portion may be a plurality of mounting grooves or mounting ports distributed circumferentially at the ends of the tube 101. In one or more implementations of the present disclosure, one end of the tube provided with a fluid inlet is used to connect a handle, and the other end is provided with a positioning cap mounting structure 115 that can cooperate with the positioning cap 104. For example, the positioning cap mounting structure 115 may be a columnar structure that is plug-fitted with the positioning cap. In one or more embodiments of the present disclosure, the positioning cap may include an end for plugging and cooperating with the positioning cap mounting structure, and also include a side that can cover each fourth connecting portion 114 circumferentially of the tube. In this way, the positioning cap 104 can be sleeved on the end of the tube and protect the connection position of the flow guide and the tube.

[0040] In one or more embodiments of the present disclosure, the deflector 102 may extend along the length of the barrel, and its inner surface may be provided with a second connection portion 125 corresponding to the first connection portion 113. In one or more embodiments of the present disclosure, the second connection portion 125 may 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 connection 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 may also be provided with a third connection portion 126 at each end for mating with the fourth connection portion 114. The third and fourth connection portions cooperate to secure the ends of each deflector to the barrel 101. In one or more embodiments of the present disclosure, the third connection portion 126 may be a plug-in structure that fits within the recessed fourth connection portion.

[0041] In one or more embodiments of the present disclosure, the guide member may further include a second guide curved surface 123 connected to the first guide curved surface 121 of the adjacent guide member, and the second guide curved surface 123 and the first guide curved surface 121 may be respectively located on both sides of the guide port 122, so that the airflow adsorbed on the first guide curved surface can flow smoothly from the first guide curved surface to another guide member adjacent to the guide member where it is located. In this way, the swirling airflow of the curling iron attachment can be made more continuous and stable, and the hair can be more evenly and smoothly wrapped around the curling iron attachment. In one or more embodiments of the present disclosure, the second guide curved surface 123 may be higher than the first guide curved surface 121. In this way, the airflow a (see Figure 11 ), can flow along the second curved guide surface connected to it to the surface of the guide member, and continue from the second curved guide surface of the guide member to the first curved guide surface of the guide member, ultimately joining the airflow a emitted from the guide port to the first curved guide surface, and together flow to the second curved guide surface of another guide member downstream of the guide member. In this way, the swirling airflow on the surface of the curling iron attachment can be made stronger, improving the efficiency and effect of hair winding.

[0042] Figure 10 A cross-sectional view showing an example structure of a flow guide of a cylindrical member according to an embodiment of the present disclosure, as shown in FIG. Figure 10As 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 11 A schematic diagram showing a cross section of a cylindrical member according to an embodiment of the present disclosure is shown. Figure 11 As shown, in one or more embodiments of the present disclosure, the outlet 112 of the cylinder connects the hollow air duct in the cylinder and the guide port corresponding to the outlet to provide airflow b 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 airflow speed entering the guide port. In one or more embodiments of the present disclosure, the flow path of the fluid 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 surface 121 when it is emitted from the guide port 122.

[0044] Figure 12 FIG. 4 is a cross-sectional view showing an exemplary structure of a flow guide 402 of another cylindrical member 40 according to an embodiment of the present disclosure, as shown in FIG. Figure 12 As shown, Figure 10The difference between the middle guide member 102 is that the guide member 402 is not provided with an inclined surface. In one or more embodiments of the present disclosure, the guide port 422 is opened on the first guide curved surface 221. In one or more embodiments of the present disclosure, the guide port 422 may include a side inlet 4221 provided on one side of the guide port, and the side inlet 4221 is connected to the outlet of the cylinder, so that the fluid flowing out of the outlet can enter the guide port 422 from the side through the side inlet 4221. The guide port 422 may also include a first guide wall 4222, which is provided below the side inlet 4221 and gradually extends upward toward the other side of the guide port to the edge of the guide port. For example, the first guide wall may be an outwardly convex arc wall. In this way, the guide port is no longer provided separately on the inclined surface, and a simpler and more stable guide member structure can be provided. In one or more embodiments of the present disclosure, the second curved guide surface 423 can smoothly connect with the first curved guide surface 421, creating a smoother surface for the curling iron attachment and ensuring smoother and more stable airflow. For example, the first and second curved guide surfaces can be different portions of the same curved surface, and the side inlet 4221 can be located within the air outlet on the side closest to the second curved guide surface. In this manner, airflow exiting the side inlet will flow from the side onto the first guide wall, then upward along the first guide wall toward the second curved guide surface on the other side and out of the air outlet, ensuring smoother and more stable airflow a generated by the curling iron. In one or more embodiments of the present disclosure, the second curved guide surface 423 is provided with a second guide wall 4231 corresponding to the outlet of the barrel. This second guide wall can guide the airflow exiting the barrel outlet along the second guide wall and into the side inlet 4221. In one or more embodiments of the present disclosure, the second guide wall can be an externally concave curved wall.

[0045] Figure 13 FIG. 4 is an exploded view showing an exemplary structure of another cylindrical member 40 according to an embodiment of the present disclosure. Figure 13 As shown, in one or more embodiments of the present disclosure, the cylindrical member 40 includes a cylinder 401 and Figure 12The guide member 402 in the barrel. A plurality of outlets 412 are provided in the length direction of the barrel 401. The difference from the barrel 101 is that a first protrusion 4121 is provided in the outlet of some barrels 401. For example, in one or more embodiments of the present disclosure, a first protrusion can be provided for each outlet, so that there is an outlet between adjacent first protrusions. A second protrusion 425 is provided on the inner side of the second guide wall corresponding to the outlet of the guide member 402. During assembly, the second protrusion of the guide member can be inserted into the corresponding outlet of the barrel for positioning. In one or more embodiments of the present disclosure, the first protrusion and the second protrusion can have mating surfaces that cooperate with each other, so that the mating surfaces of the first protrusion and the second protrusion partially overlap. At the same time, the mating surface of the second protrusion is provided with a limiting portion 4251 located at the bottom of the first protrusion, thereby limiting the guide member in the radial direction of the barrel. Figure 14 FIG. 4 is a schematic diagram showing a cross section of another cylindrical member 40 according to an embodiment of the present disclosure. Figure 14 As shown, in one or more embodiments of the present disclosure, a guide channel 4252 is provided on the other surface of the second protrusion 425 opposite the mating surface. In this way, when the second protrusion is inserted into the outlet of the tube, the 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 tube, and inserts matching the shape of the groove can be provided on both sides of the guide member. The grooves of the guide member are inserted into the corresponding slots from the end face of the tube, and the guide member can be installed on the tube to assemble into a cylindrical member.
