Description

Technical Field

[0001] This invention relates to the technical field of hair styling tools, specifically to a hair curling attachment and a hair curling device. Background Technology

[0002] Hair curling devices, such as curling irons, work by blowing airflow along the circumference of the iron. When the iron contacts the hair, the hair is drawn in by the airflow and wraps around the outer edge of the iron. The continuous heat from the airflow then sets the hair into a specific curl. However, traditional curling irons often result in the hair wrapping around the same spot on the iron, rather than curling sequentially along the iron's axis. This leads to two problems: firstly, the curl is less than ideal, as the outer hair wraps around the outer edge of the inner hair, resulting in a larger curl on the outer side; secondly, because the outer hair is farther from the center of the iron, heat is less effectively conducted to it, making it harder to set and ultimately failing to achieve the desired curl. Summary of the Invention

[0012] Optionally, each of the extended inner wall surfaces includes a first wall section, a second wall section, and a third wall section that are sequentially connected along the circumference of the roll body, with each first wall section located at one end close to the corresponding air outlet. In the radial direction of the main body of the drum, the first wall section is located outside the corresponding air outlet; in the circumferential direction of the main body of the drum and in the first direction, the distance between the second wall section and the air guide is gradually increased to form the guiding structure.

[0013] Optionally, the distance between the second wall section and the air guide is gradually reduced along the circumference of the main body of the drum and along the first direction.

[0020] The technical solution provided by this invention has the following beneficial effects: The hair curling accessory provided by this invention includes a curling cylinder body and an air guide. One axial end of the curling cylinder body is adapted to connect to the main body of a hair curling device, allowing airflow generated within the main body to enter an airflow channel on the curling cylinder body. The airflow flowing through the airflow channel can then be blown out through multiple air outlets on the air guide. Furthermore, by providing an extension portion on the outer side of each air outlet, extending the extension portion circumferentially along the air guide to form an air guide channel with the outer periphery of the air guide, the airflow blown out of the air outlet is guided towards one side of the circumference of the air guide, thereby allowing the generated airflow to flow better along the circumference of the air guide. During hair curling, the hair can be better wrapped around the outer side of the air guide under the attraction of the airflow, curling and fixing the hair to the outer side of the air guide, thus achieving hair curling and styling. Furthermore, the non-planar design of the air nozzles allows the airflow from each nozzle to flow downwards along the circumference of the curling attachment. As the hair wraps around the outer perimeter of the curling attachment along the circumference of the curling attachment, it also flows downwards along the axial direction of the curling attachment, allowing the ends of the hair to wrap around the bottom of the attachment, while the end closer to the roots wraps around the top. The hair spirals around the curling attachment along the axial direction of the curling attachment, resulting in more dispersed hair, more consistent curl throughout, and a better styling effect. It also facilitates the heating and styling of the hair with the hot airflow, and the downward pulling force of the airflow makes the hair easier to style, making the process more convenient for the user.

[0028] This invention provides a hair curling attachment 100, which is adapted to a hair curling device. Specifically, please refer to... Figures 1 to 3 In this embodiment, the hair curling accessory 100 includes a curling tube body 1 and an air guide 2. An airflow channel 12 is formed inside the curling tube body 1, which is adapted to communicate with the airflow forming device inside the hair curling device. The air guide 2 is sleeved on the outside of the curling tube body 1, and a plurality of air outlets 22 connected to the airflow channel 12 are opened on its peripheral sidewall. Each air outlet 22 has an extension 32 on its outer side, and each extension 32 extends along the circumference of the curling tube body 1 and together with the outer peripheral surface of the air guide 2 to form an air guide channel 35. One end of each air guide channel 35 is connected to the corresponding air outlet 22, and the other end forms a blower 324. The air outlet cross section of each blower 324 is non-planar, so that the airflow blown from each blower 324 can flow along the circumference of the curling tube body 1 and flow downwards at an angle.

[0029] In this embodiment, the main body 1 of the roller is adapted to be detachably connected to the main body of the hair curling device, and each main body can be fitted with one or more hair curling attachments 100. An airflow forming device (such as a fan or air pump) may be provided inside the main body of the device, and one axial end of the main body 1 is adapted to be connected to the main body of the device, so that the airflow formed by the airflow forming device can enter the airflow channel 12 on the main body 1 of the roller, and the airflow can be blown out from multiple air outlets 22 by the guidance of the airflow channel 12.

[0030] Furthermore, by providing an extension 32 on the outer side of each air outlet 22, extending the extension 32 circumferentially along the air guide 2 to form an air guide channel 35 between the extension 32 and the outer periphery of the air guide 2, the airflow blown from the air outlet 22 can be guided towards one side of the circumference of the air guide 2 through the air guide channel 35, thereby allowing the airflow to flow better along the circumference of the air guide 2. When curling hair, the hair can be better wrapped around the outer side of the air guide 2 under the attraction of the airflow, curling and fixing the hair to the outer side of the air guide 2, thus achieving hair curling and styling. Furthermore, by setting the air outlets 22 to be non-planar, the airflow from each air outlet 22 can flow downwards along the circumference of the curling tube body 1. While the hair wraps around the outer periphery of the curling attachment 100 along the circumference of the curling tube body 1, it can also flow downwards along the axial direction of the curling tube body 1 with the airflow. This allows the hair ends to wrap around the bottom of the curling attachment 100, while the end near the roots can wrap around the top near the curling attachment 100. The hair spirally wraps around the curling attachment 100 along the axial direction of the curling tube body 1, resulting in more dispersed hair on the attachment, more consistent curl throughout, and a better styling effect. It also facilitates the heating and styling of the hair with hot airflow, and the downward traction of the airflow makes the hair easier to style, making it more convenient for the user.

[0031] Understandably, during the curling process, the hair is wrapped around the curling attachment 100 sequentially from the ends. However, with traditional curling attachments, the airflow blows circumferentially around the attachment. When the hair comes into contact with the attachment, the airflow pulls the hair in, causing it to curl and wrap around the attachment circumferentially. But this method tends to cause the hair to wrap around a portion of the attachment's axis instead of spiraling along its axis. This affects the curling effect and also results in lower utilization of the curling attachment.

[0032] Therefore, in this embodiment, the airflow from the blower nozzle 324 is configured to flow in a downward spiral along the axial direction of the curling tube body 1. This allows the hair to wrap around the outer periphery of the curling tube body 100 under the influence of the downward airflow when the ends of the hair come into contact with the curling attachment 100. Simultaneously, the ends of the hair gradually move downwards, allowing them to wrap around the bottom of the curling attachment 100, while the end near the root wraps around the top of the attachment. The hair spirally wraps around the curling attachment 100 along the axial direction of the curling tube body 1, resulting in more dispersed hair and a more consistent curl across the attachment. This facilitates the heating and styling of the hair by the hot airflow, and the downward traction of the airflow also makes the hair easier to style, making the operation more convenient for the user.

[0033] Specifically, each air outlet 22 is elongated and narrow, extending along the axial direction of the main body 1, and preferably, each air outlet 22 is inclined downwards along the axial direction of the main body 1. For the left-hand curling attachment 100, such as... Figure 1 As shown, each air outlet 22 extends obliquely to the left in the direction along the axial direction of the main body 1 and from bottom to top. For the right-hand curling attachment 100, as... Figure 4 As shown, each air outlet 22 extends obliquely to the right in the direction of upward movement along the axial direction of the drum body 1, so that the airflow blown from each air outlet 22 can flow obliquely downward along the axial direction of the drum body 1. Preferably, the oblique angle of each air outlet 22 is approximately 45º.

[0034] Combination Figures 7 to 9 As shown, each extension portion 32 has a stepped portion 323 at the end away from the corresponding air outlet 22. The stepped portion 323 divides the air outlet 324 into a first air outlet section 351 and a second air outlet section 352. The stepped surface 3231 of the stepped portion 323 connects the first air outlet section 351 and the second air outlet section 352. The first air outlet section 351 is located above the second air outlet section 352, and the distance between the first air outlet section 351 and the corresponding air outlet 22 is greater than the distance between the second air outlet section 352 and the air outlet 22. The air outlet 324 is arranged in a non-planar manner, that is, along the circumference of the drum body 1, the extension length of the lower part of each extension portion 32 is less than the extension length of the upper part of each extension portion 32, so that a discontinuity is formed at the air outlet 324.

[0035] Furthermore, the gap area between the first blowing section 351 and the second blowing section 352 is designated as a buffer zone. Combined with... Figure 8 and Figure 9 The dashed arrow indicates the airflow direction. Since the second blowing section 352 is closer to the air outlet 22, some airflow will first be blown out from the second blowing section 352 and enter the larger external space. Obviously, the airflow velocity after being blown out from the second blowing section 352 to the outside will decrease, while some airflow will still flow within the air guide channel 35 and then flow out from the step surface 3231 and the second blowing section 352 respectively. The airflow velocity from the first blowing section 351 and the step surface 3231 will be significantly greater than the airflow velocity after being blown out from the second blowing section 352 and entering the buffer area, and the airflow velocity from the first blowing section 351 will be the maximum. Since the airflow will flow from the side with lower velocity to the side with higher velocity, the overall airflow will move towards the side of the first blowing section 351, making the overall airflow angle slightly smaller than the tilt angle of the airflow blown out from the air outlet 324. Let α1 be the angle between the airflow from the air outlet 324 and the horizontal plane. Then... This ensures that the twist distance of the hair wrapped around the outer periphery of the curling attachment 100 is not too large, thus guaranteeing the hair-up effect while allowing the curling attachment 100 of the same length to wrap around longer hair.

[0036] Preferably, in the axial direction of the drum body 1 and from top to bottom, the air outlet section of the first blowing section 351 is inclined downwards and gradually approaches the corresponding air outlet 22. In the axial direction of the drum body 1 and from top to bottom, the air outlet section of the second blowing section 352 is inclined downwards and gradually approaches the corresponding air outlet 22. This better guides the air outlet direction downwards along the axial direction of the drum body 1.

[0037] The air outlet angle can be controlled by adjusting the height of the first air blowing section 351, the height of the second end, and the relative distance between the first air blowing section 351 and the second air blowing section 352. The height of the first air blowing section 351 and the height of the second air blowing section 352 refer to the extension length of the first air blowing section 351 and the second air blowing section 352 along the axial direction of the drum body 1.

[0038] Preferably, along the circumferential direction of the drum body 1, the length of the first blowing section 351 protruding from the second blowing section 352 is 1 / 3 to 2 / 3 of the length of the corresponding extension 32. Along the axial direction of the drum body 1, the ratio of the height of the first blowing section 351 to the height of the second blowing section 352 is 0.8 to 1.5. By controlling the length of the first blowing section 351 protruding from the second blowing section 352 in the circumferential direction to within 1 / 3 to 2 / 3 of the length of the corresponding extension 32, an airflow channel 12 with a clearly defined guiding boundary can be formed. This ensures that the airflow is uniformly and continuously guided and constrained when entering the outlet area, preventing premature deflection, localized flow separation, or angular drift of the airflow due to excessive or insufficient end-face protrusion. Meanwhile, by limiting the ratio of the height of the first blowing section 351 to the height of the second blowing section 352 in the axial direction to 0.8 to 1.5, it is possible to ensure that the two end faces form a matching guide gradient in the axial extension length, making the velocity distribution of the airflow in the axial direction more balanced. This achieves precise control and stable output of the air outlet angle, significantly improving the consistency and controllability of the air outlet direction. Preferably, the angle α2 between the airflow blown out of the blower 324 and the horizontal plane is 25º to 35º, and more preferably 30º. This air outlet angle makes it easier to style hair, and the hair is more compactly distributed on the curling attachment 100, making it suitable for a wider range of hair lengths.

[0039] Of course, the non-planar arrangement of the air outlet 324 includes, but is not limited to, the one described above. In other embodiments, the air outlet 324 may also be arranged in an arc shape, for example, recessed on the side facing the air outlet, so that the air outlet can be more concentrated and uniform. Alternatively, the air outlet 324 may also be in the form of multiple steps or a combination of arc and steps, etc.

[0040] Among them, combined Figure 2 and Figure 3 As shown, the main body 1 of the reel is generally cylindrical, and its interior is hollow to form the airflow channel 12. One axial end of the main body 1 is open and connected to the main body of the device, while the other axial end is open and can be closed by an end cap, or the other axial end of the main body 1 is closed. Assuming the axial direction of the main body 1 is vertical, the closed end of the main body 1 is considered the upper end, and the end connected to the main body of the device is considered the lower end. Unless otherwise specified, all descriptions of orientation in this invention shall be taken as above.

[0041] The main body 1 of the scroll has multiple perforated areas on its peripheral sidewall. These perforated areas can correspond one-to-one with multiple air outlets 22. Alternatively, the number of perforated areas can be greater than or less than the number of air outlets 22. The multiple perforated areas allow the airflow channel 12 to connect with the multiple air outlets 22. Preferably, the multiple perforated areas are arranged in an array along the circumference of the main body 1, resulting in a larger area occupied and higher airflow efficiency.

[0042] The shape of the air guide 2 is adapted to the shape of the drum body 1, and the air guide 2 is fixedly sleeved on the outer periphery of the drum body 1. Specifically, on the inner peripheral wall of the air guide 2 and the outer peripheral wall of the drum body 1, one is provided with a limiting protrusion 24, and the other is provided with a limiting groove 11 that cooperates with the limiting protrusion 24. Both the limiting protrusion 24 and the limiting groove 11 extend along the axial direction of the drum body 1. By locking the limiting protrusion 24 in the limiting groove 11, the rotation of the air guide 2 relative to the drum body 1 is restricted.

[0043] Preferably, a plurality of limiting protrusions 24 are provided on the inner peripheral wall of the air guide 2, and the plurality of limiting protrusions 24 are arranged at intervals along the circumference of the air guide 2. A plurality of limiting grooves 11 are provided on the outer peripheral wall of the drum body 1, and the plurality of limiting protrusions 24 are correspondingly engaged in the plurality of limiting grooves 11. During assembly, the air guide 2 can be sleeved from the top of the drum body 1 downwards, and the plurality of limiting protrusions 24 are correspondingly engaged in the plurality of limiting grooves 11. Under the guiding action of the plurality of limiting protrusions 24 and the plurality of limiting grooves 11, the air guide 2 can move better along the drum body 1, making installation more convenient.

[0044] Furthermore, an outer edge portion is provided on the outer periphery of the bottom of the main body 1 of the scroll, and the outer edge portion is arranged in a ring around the outer periphery of the main body 1 of the scroll. When the hair curling accessory 100 is installed on the main body of the device, the outer edge portion abuts against the docking interface of the main body of the device. When the air guide 2 is assembled with the main body 1 of the scroll, the air guide 2 can slide downward from the upper end of the main body 1 of the scroll, so that multiple limiting protrusions 24 correspond one-to-one with multiple limiting grooves 11, and then slide downward into the main body 1 of the scroll until the lower end of the air guide 2 abuts against the outer edge portion, indicating that the air guide 2 is installed in place. An end cap may also be provided at the upper end of the main body 1 of the scroll. The end cap is detachably provided on the main body 1 of the scroll. After the air guide 2 is installed in place, the end cap is placed on the upper end of the air guide 2, thereby limiting the air guide 2 in the axial direction, so that the air guide 2 and the main body 1 are relatively fixed in both the axial and circumferential directions.

[0045] Multiple air outlets 22 located on the same circumferential surface are grouped together. Multiple groups of air outlets 22 are provided along the axial direction of the drum body 1, and the multiple groups of air outlets 22 are stacked along the axial direction of the drum body 1.

[0046] In one embodiment, multiple sets of air outlets 22 are staggered along the axial direction of the drum body 1, meaning that the multiple air outlets 22 in the previous set do not correspond axially to the multiple air outlets 22 in the next set. This allows the air outlets 22 to occupy a larger area along the circumferential direction of the drum body 1, better avoiding airflow breaks in the circumferential direction, resulting in better hair adhesion in the circumferential direction, and allowing the hair to be better wrapped around the outside of the air guide 2.

[0047] Alternatively, multiple sets of air outlets 22 can be arranged in a one-to-one correspondence along the axial direction of the main body 1 of the curling cylinder, meaning that multiple air outlets 22 in one set correspond one-to-one with multiple air outlets 22 in the next set along the axial direction. This makes the airflow direction of each set of air outlets 22 more consistent, and the airflow distribution along the axial direction of the main body 1 more uniform, resulting in a more consistent curl curvature throughout the hair and a better curling effect.

[0048] The number of air outlets 22 in each group of air outlets 22 is not specifically limited, and can be reasonably set according to the outer diameter of the air guide 2 so that the hair curling attachment 100 can be better applied. Moreover, the outer extension 32 of each air outlet 22 can be set in a consistent or inconsistent manner.

[0049] Preferably, multiple sets of air outlets 22 are arranged in a one-to-one correspondence along the axial direction of the main body 1 of the hair roller, and the multiple extensions 32 are arranged in the same way. On the one hand, this can better ensure that the air outlet effect of the hair curling attachment 100 is more consistent at all points along the axial direction, and the air outlet direction is easier to control. On the other hand, it is also more convenient to manufacture and the manufacturing cost is lower.

[0050] The shape of the outer peripheral surface of the air guide 2 is not specifically limited, as long as the airflow can flow along it better and form an airflow that flows circumferentially along the drum body 1. In one embodiment, the outer peripheral surface of the air guide 2 is a flat arc surface, and the air outlet 22 is provided on the peripheral sidewall of the air guide 2. The airflow blown out of the air outlet 22 is radially outward along the air guide 2. At this time, the extension 32 can be placed on the outside of the air outlet 22. The extension 32 is arc-shaped and extends radially outward from the air outlet 22 and then extends circumferentially along the drum body 1, thereby guiding the airflow to one side of the circumferential direction of the air guide 2.

[0051] Alternatively, in another embodiment, the outer peripheral surface of the air guide 2 is non-flat. Specifically, the air guide 2 includes at least one inner air guide ring 21, each inner air guide ring 21 including an upper air guide ring 211 and a lower air guide ring 212, and a plurality of air guide walls 213 connecting the upper air guide ring 211 and the lower air guide ring 212. The plurality of air guide walls 213 are arranged sequentially along the circumference of the drum body 1, and the plurality of air guide walls 213 are all arranged to extend outwardly from the lower air guide ring 212 along the circumference of the drum body 1. The upper air guide ring 211 is connected to the top of the extended ends of the plurality of air guide walls 213.

[0052] Because each air guide wall 213 extends outward in the circumferential direction along the drum body 1, a discontinuity region is formed between the starting and ending ends of each air guide wall 213 in the radial direction along the drum body 1. That is, the outer diameter of each upper air guide ring 211 is larger than the outer diameter of each lower air guide ring 212. In this way, each extension portion 32 can be disposed on the outside of the corresponding air guide wall 213, so as to be located in the discontinuity region formed by each air guide wall 213, making the extension portion 32 and the air guide 2 more compact and occupying less radial space. Among them, in every two adjacent air guide walls 213 in the circumferential direction along the drum body 1, the starting end of the latter air guide wall 213 and the ending end of the former air guide wall 213 are spaced apart in the radial direction along the drum body 1 to form an air outlet 22. In this way, the air outlet 22 is oriented towards the circumferential side of the main body 1 of the roller, and the airflow can be blown out more along the circumference of the main body 1 of the roller. Under the guidance of the air guide wall 213, a vortex airflow is formed. When the airflow flows along the air guide wall 213, it has a certain internal swirling force, which can better attract and adhere the hair to the outside of the air guide 2.

[0053] The following description will primarily focus on the specific structure of the hair curling accessory 100, exemplified by multiple sets of air outlets 22 arranged in a one-to-one correspondence along the axial direction of the main body 1, with the corresponding extension portion 32 at each air outlet 22 having a consistent arrangement, and each air outlet 22 facing one side of the main body 1 in the circumferential direction. However, this does not limit the structure of the hair curling accessory 100; other arrangements of the air outlets 22 and extension portions 32 can be adapted accordingly.

[0054] In this configuration, along the axial direction of the drum body 1, the length of each extension portion 32 is adapted to the length of the corresponding air outlet 22, ensuring that the airflow blown from each air outlet 22 can be better guided into the air guide channel 35 under the action of the extension portion 32. However, the corresponding air guide channel 35 and the air outlet 22 are not tightly connected, forming a first air outlet gap 4. Specifically, one end of each extension portion 32 faces the corresponding air outlet 22, and the other end extends circumferentially away from the air outlet 22 along the drum body 1. The end of each extension portion 32 near the air outlet 22 forms a first air outlet gap 4 with the corresponding air outlet 22. The first air outlet gap 4 extends radially along the drum body 1, and the airflow blown from the first air outlet gap 4 is radially outward along the drum body 1.

[0055] That is, no sealing structure is provided at the junction of the extension 32 and the air outlet 22, and the two are set with a certain gap along the circumference of the drum body 1, so that a small part of the airflow flowing out from the air outlet 22 can be blown out from the first air outlet gap 4 at the junction of the extension 32 and the air outlet 22 to form an airflow blowing outward along the radial direction of the drum body 1.

[0056] When curling hair, the hair is usually divided into sections and then curled one section at a time using the curling attachment 100. Understandably, each section of hair will not naturally separate, especially when the hair is damp or sticky after using hair care products, making it prone to clumping. Because the airflow from the first air outlet gap 4 is radially outward, it disperses the clumps of hair, allowing them to spread evenly along the axial direction. This allows the hair to be better laid out and curled evenly around the curling attachment 100, forming a thin, uniform layer, preventing excessive thickness of hair in localized areas outside the air guide 2, which would result in poor curl setting.

[0057] Regarding the specific structure of the air outlet 22, each air outlet 22 has a first edge surface 221 and a second edge surface 222 arranged opposite to each other along the radial direction of the drum body 1, with the second edge surface 222 located outside the first edge surface 221. That is, in the two air guide walls 213 arranged adjacent to each other along the circumference of the drum body 1, the first edge surface 221 is located at the extended end of the preceding air guide wall 213, and the second edge surface 222 is located at the extended beginning of the following air guide wall 213. The air outlet 22 is formed by the two air guide walls 213, and each air guide wall 213 extends spirally in the circumference, so that the airflow can flow better to each air outlet 22 and flow along the outer wall surface of each air guide 2.

[0058] The first air outlet gap 4 is formed between the extension portion 32 and the second edge surface 222, and an air guide channel 35 is formed between the extension portion 32 and the side wall where the first edge surface 221 is located. Furthermore, a second air outlet gap 5 is also formed between the top of each extension portion 32 and each upper air guide ring 211 at intervals. The second air outlet gap 5 is connected to the air outlet 22. The width of the second air outlet gap 5 along the axial direction of the drum body 1 is narrower, and its length along the circumferential direction of the drum body 1 is adapted to the length of the extension portion 32. Because the air outlet space of the second air outlet gap 5 is relatively small, the airflow velocity from the second air outlet gap 5 is greater than the airflow velocity inside the air guide channel 35. The airflow from the second air outlet gap 5 can cause the downward-blowing airflow to tilt slightly upward, so that the airflow from the blower nozzle 324 will not tilt too downward along the axis of the curling body 1, thereby improving the air outlet angle. This can improve the winding pitch of the hair around the outer periphery of the curling attachment 100, making the hair more compactly arranged along the axis of the curling body 1 after being styled. The curling attachment 100 of the same length can wrap a longer length of hair. By connecting and guiding each air outlet 22 with each extension portion 32, three air outlet positions are formed between each extension portion 32 and the corresponding air outlet 22: the first air outlet gap 4, the second air outlet gap 5, and the blower nozzle 324. The combination of three air outlets not only improves the hair-styling effect but also ensures the evenness of the hair-styling process, resulting in better curling effect from the curling attachment 100 and a better user experience.

[0059] Furthermore, the cross-sectional area of ​​at least a portion of each air guide channel 35 is larger than the cross-sectional area of ​​the corresponding air outlet 22. It should be noted that the aforementioned cross-section refers to a cross section perpendicular to all streamlines in the airflow, and the velocity direction of the airflow is perpendicular to the cross section when passing through it. The air outlet 22 is planar, and its outlet end face forms the cross-sectional area of ​​the air outlet 22, with the airflow blowing out in a direction perpendicular to the air outlet 22. The air guide channel 35 extends approximately circumferentially along the air guide member 2, and its cross-sectional area is the cross-section of the air guide channel 35 along the circumference of the drum body 1. The area of ​​at least a portion of the flow cross section of the air guide channel 35 is set to be larger than the area of ​​the flow cross section of the air outlet 22, so that the space inside the air guide channel 35 is larger than that at the air outlet 22. The larger space inside the air guide channel 35 results in lower air pressure, and the airflow tends to flow from the high pressure area to the low pressure area. Therefore, it can better increase the rate at which the airflow enters the air guide channel 35, thereby increasing the air volume of the air outlet 324.

[0060] Specifically, each extension 32 is arranged to extend inward in a spiral manner along the circumference of the main body 1 of the drum, so that the space of the air guide channel 35 at the end near the air outlet 22 tends to be larger, so that the airflow can enter the air guide channel 35 better, while the space at the end near the air outlet 324 tends to be smaller, so that the airflow blowing from each air outlet 324 has a greater flow rate, higher air outlet efficiency, and better air outlet directionality.

[0061] Regarding the specific structure of the outer extension 32, each air outlet 22 is positioned circumferentially towards the main body 1 of the curling tube and in a first direction. The curling attachment 100 can be divided into a left-handed curling attachment 100 and a right-handed curling attachment 100. On the left-handed curling attachment 100, the first direction refers to the view from the top of the axial direction of the main body 1, and each outer extension 32 extends clockwise along the circumference of the main body 1. On the right-handed curling attachment 100, the first direction refers to the view from the top of the axial direction of the main body 1, and each outer extension 32 extends counterclockwise along the circumference of the main body 1. Generally, the left-handed curling attachment 100 is suitable for curling the left side of the hair, and the right-handed curling attachment 100 is suitable for curling the right side of the hair. Of course, they can be used alternately to suit different styles, and the specific usage is not limited. Figure 1 and Figure 4 As shown, in the radial projection of the main body 1, the extension 32 of the left-hand curling attachment 100 extends from the air outlet 22 toward the left, and the extension of the right-hand curling attachment 100 extends from the air outlet 22 toward the right.

[0062] Combination Figure 5 and Figure 6 As shown, each extension portion 32 has an extended inner wall surface 321 and an extended outer wall surface 322 extending circumferentially along the main body 1. The shapes of the extended inner wall surface 321 and the extended outer wall surface 322 are adapted to each other, making the wall thickness of the extension portion 32 more uniform. In the radial direction along the main body 1, the extended outer wall surface 322 is located outside the extended inner wall surface 321, and an air guide channel 35 is formed between the extended inner wall surface 321 and the air guide 2. The extended inner wall surface 321 has a guiding structure at one end near the corresponding air outlet 22. The guiding structure is used to guide the airflow blown from the air outlet 22 into the air guide channel 35. Through the guiding effect of the guiding structure, the airflow can enter the air guide channel 35 more quickly and then flow along the extended inner wall surface 321. The extended inner wall surface 321 can further guide the airflow towards the air outlet 324 to improve the air outlet efficiency.

[0063] Furthermore, such as Figure 6As shown, each extended inner wall surface 321 includes a first wall section 3211, a second wall section 3212, and a third wall section 3213 sequentially connected along the circumference of the drum body 1. Each first wall section 3211 is located near the end of its corresponding air outlet 22, and each third wall section 3213 is located near the end of its corresponding air outlet 324. The second wall section 3212 connects the first wall section 3211 and the third wall section 3213. When the airflow enters the air guide channel 35, it first flows through the first wall section 3211. In the radial direction along the drum body 1, the first wall section 3211 is located outside the corresponding air outlet 22, such that the flow cross-section formed between the first wall section 3211 and the outer wall of the air guide wall 213 is larger than the flow cross-section of the air outlet 22, allowing the airflow to flow more effectively into the air guide channel 35. Furthermore, along the circumference of the drum body 1 and along the first direction, the distance between the second wall section 3212 and the air guide 2 gradually increases to form a guiding structure. By gradually moving the second wall section 3212 further away from the corresponding air guide wall 213, the air intake space near the air outlet 22 gradually increases, forming a gradually increasing air guide space. The airflow can continuously and stably flow in the direction of the air guide channel 35, making it less likely to form turbulence inside the air guide channel 35. The airflow direction is more stable, and thus the air outlet is also more stable.

[0064] Furthermore, along the circumference of the main body 1 and along the first direction, the distance between the third wall section 3213 and the air guide 2 is gradually reduced. The second wall section 3212 increases the flow cross-section of the air guide channel 35, but it is understood that the flow cross-section of the air guide channel 35 should not be too large to avoid excessive reduction in airflow velocity, which would affect the airflow effect. Therefore, while ensuring the air intake velocity of the air guide channel 35 through the second wall section 3212, the flow cross-section between the third wall section 3213 and the corresponding air guide wall 213 is further reduced, thereby decreasing the area of ​​the flow cross-section at the air outlet 324 to increase the airflow velocity. This allows the hair to be better adhered to the outside of the air guide 2 under the action of the airflow, resulting in better hair removal. The area of ​​the flow cross-section at the air outlet 324 is equal to or slightly smaller than the area of ​​the flow cross-section at the air outlet 22.

[0065] It is understandable that each extension portion 32 can be directly mounted on the air guide 2, and the multiple extension portions 32 and the inner air guide ring 21 can be integrally mounted. Alternatively, each extension portion 32 can be detachably mounted on the outside of the air guide 2. The mounting method of the extension portions 32 will vary depending on the different mounting methods of the air guide 2.

[0066] For example, only one inner air guide ring 21 may be provided. In this case, the axial dimension of the inner air guide ring 21 is relatively large, that is, the entire inner air guide ring 21 is roughly cylindrical, and its shape matches the shape of the drum body 1. The inner air guide ring 21 is fitted onto the outside of the drum body 1, and multiple air outlets 22 are provided on the peripheral sidewall of the inner air guide ring 21. During assembly, multiple extension parts 32 can be assembled onto the outside of the inner air guide ring 21 first, and then the inner air guide ring 21 can be fitted onto the outside of the drum body 1 from one end. At this time, each extension part 32 can be fixed to the outside of the inner air guide ring 21 by means of insertion, snap-fit, and / or magnetic attraction, which facilitates the disassembly, assembly, and maintenance of each extension part 32.

[0067] Preferably, multiple inner air guide rings 21 are provided. In this case, the axial dimension of each inner air guide ring 21 is smaller than that of the previous embodiment. The multiple inner air guide rings 21 are stacked around the circumference of the roller body 1, and the multiple inner air guide rings 21 together surround the outer periphery of the roller body 1. Adjacent inner air guide rings 21 are stacked in the vertical direction, and each inner air guide ring 21 is provided with the aforementioned limiting protrusion 24. Each inner air guide ring 21 can be fitted onto the roller body 1 one by one. In this way, when the axial length of the roller body 1 changes, a corresponding number of inner air guide rings 21 can be matched accordingly, which can better adapt to the installation requirements of hair curling accessories 100 of different lengths, and improve assembly adaptability.

[0068] When multiple inner air guide rings 21 are provided, combined with Figure 2 and Figure 10 As shown, the hair curling accessory 100 also includes multiple outer air guide rings 31, each of which has multiple extensions 32. The multiple outer air guide rings 31 are fitted one-to-one onto the outer periphery of multiple lower air guide rings 212, and the multiple extensions 32 on each outer air guide ring 31 are arranged one-to-one with the multiple air outlets 22 on each inner air guide ring 21. The multiple extensions 32 located on the same circumferential surface are connected and fixed by the outer air guide rings 31. Preferably, the multiple extensions 32 are integrally formed with their corresponding air guide rings. During installation, the outer air guide rings 31 are fitted onto their corresponding lower air guide rings 212, allowing the multiple extensions 32 to be installed simultaneously, making assembly more convenient and ensuring more precise alignment between the extensions 32 and the air outlets 22.

[0069] Specifically, each inner air guide ring 21 is provided with a first mounting part 23, and each outer air guide ring 31 is provided with a first mating part 33. Each first mounting part 23 and its corresponding first mating part 33 are mutually restrictive to limit the relative rotation of each inner air guide ring 21 and its corresponding outer air guide ring 31 along the circumference of the drum body 1. After each outer air guide ring 31 is fitted onto its corresponding inner air guide ring 21, the first mounting part 23 and its corresponding first mating part 33 are mutually restrictive to limit the two in the circumferential direction, preventing them from rotating relative to each other in the circumferential direction.

[0070] Among them, combined Figure 10 As shown, each outer air guide ring 31 is approximately circular, and each outer air guide ring 31 has multiple extensions 32 at its top, which are spaced apart circumferentially along the outer air guide ring 31. The first mating part 33 consists of multiple limiting protrusions 331, with at least one limiting protrusion 331 between each pair of adjacent extensions 32. As each air guide wall 213 extends outward from the lower air guide ring 212, a gap gradually forms between each air guide wall 213 and its corresponding lower air guide ring 212. A connecting wall is provided between each air guide wall 213 and its corresponding lower air guide ring 212. The first mounting part 23 includes a first groove 231 at the bottom of the connecting wall, and the multiple first grooves 231 correspond one-to-one with the multiple limiting protrusions 331. Each outer air guide ring 31 can be fitted onto the bottom of each inner air guide ring 21, so that multiple limiting protrusions 331 can be inserted one by one into multiple first grooves 231, thereby limiting the relative positioning of the outer air guide ring 31 and the corresponding inner air guide ring 21 in the circumferential direction. Moreover, when the limiting protrusions 331 and the first grooves 231 are in an interference fit, the outer air guide ring 31 is not easy to loosen or fall off after being fitted onto the inner air guide ring 21, which makes it easier to stack multiple sets of outer air guide rings 31 and inner air guide rings 21.

[0071] Furthermore, each upper air guide ring 211 is provided with a second mounting portion 2111, and each outer air guide ring 31 is provided with a second mating portion 34. Along the axial direction of the drum body 1, the second mounting portion 2111 on the preceding inner air guide ring 21 and the second mating portion 34 on the outer air guide ring 31 of the following inner air guide ring 21 are mutually restrictive and engaged to limit the radial relative movement of two adjacent inner air guide rings 21 in the drum body 1, so that there is no relative movement between the upper and lower inner air guide rings 21 and between the upper and lower outer air guide rings 31. Each inner air guide ring 21 and each outer air guide ring 31 form an air guide structure. The multiple air guide structures are stacked and limited in the axial direction. In the circumferential direction, the limiting protrusion 24 on the inner air guide ring 21 cooperates with the limiting groove 11 on the drum body 1 for limitation. In the radial direction, the second mounting part 2111 and the second mating part 34 cooperate for limitation, so that the multiple air guide structures are completely limited, which is more stable and reliable, and the air outlet direction is also more stable, avoiding airflow interference between adjacent air guide structures.

[0072] The second mounting part 2111 includes a limiting ring 2111a protruding from the top of each upper air guide ring 211, and each limiting ring 2111a is coaxially arranged with the corresponding upper air guide ring 211. The second mating part 34 includes a second groove 341 provided at the bottom of each corresponding outer air guide ring 31, and the second groove 341 is annularly arranged and coaxially arranged with the corresponding outer air guide ring 31. When two adjacent air guide structures are stacked, after the lower air guide structure is installed, the upper air guide structure is sleeved on the drum body 1. The limiting ring 2111a on the lower air guide structure is inserted into the second groove 341 on the upper air guide structure, so that the two adjacent air guide structures are in contact. This not only positions the two air guide structures, but also makes the connection between the two adjacent air guide structures tighter and without gaps, making it less likely for air to leak out.

[0073] The present invention also provides a hair curling device, which includes a device body and the aforementioned hair curling attachment 100. The hair curling attachment 100 is detachably mounted on the device body, and at least two hair curling attachments 100 are provided. By equipping various models and / or sizes of hair curling attachments 100, it can better suit different users and different usage needs.

[0074] Understandably, when curling hair, the curling directions of the left and right sides of the hair are exactly opposite. Therefore, in the plurality of curling attachments 100, the air outlet 22 and the extension direction of the outer extension 32 on at least one curling attachment 100 are both arranged facing a first direction, and the air outlet 22 and the extension direction of the outer extension 32 on at least one curling attachment 100 are both arranged facing a second direction, with the first and second directions being opposite along the circumference of the curling tube body 1. This allows one curling attachment 100 to be used for curling the left side of the hair, and another curling attachment 100 to be used for curling the right side of the hair.

[0075] For example, when curling the hair on the left side, the curling attachment 100 used at this time has its outer extensions 32 extending to the left from each air outlet 22 on the radial projection of the curling attachment 100, with the airflow direction rotating downwards to the left. The ends of the hair will curl inwards from the outside of the curling attachment 100 towards the inside of the face, while the ends will move downwards along the axis of the curling attachment 100. This is suitable for inward curls, face-shaping, and gentle hairstyles. When the curling attachment 100 is applied to the hair on the right side, the ends will flip outwards towards the right side of the face, suitable for creating outward curls, parted bangs, and large, outward-expanding waves.

[0076] If a right-handed curling attachment 100 is used instead, specifically, when each extension 32 of the curling attachment 100 extends to the right from each air outlet 22 on the radial projection of the curling attachment 100, the airflow direction is downward and to the right. When curling the hair on the left side, the ends will flip outwards towards the right side of the face, suitable for creating outward-curling, parted bangs, or large, wavy hairstyles. When curling the hair on the right side, the ends will curl inwards from the outside of the curling attachment 100 towards the inside of the face, while simultaneously moving downwards along the axis of the curling attachment 100. This is suitable for inward curls, face-shaping, and gentle, warm hairstyles.

[0077] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure made using the contents of the present invention specification and drawings, or any direct or indirect application in other related technical fields, are similarly included within the patent protection scope of the present invention.
