Description

Technical Field

[0001] This utility model relates to the field of styling tools technology, specifically to a styling tool and a hair care device. Background Technology

[0002] In the field of hair care, styling tools are key components for achieving hair styling, and the airflow distribution plays a crucial role. The placement of the air outlet directly affects styling efficiency and user experience. In actual use, styling tools such as curling irons often require tilting to adapt to different styling angles. Due to gravity, hair tends to droop, making it impossible to completely cover the styling tool. When the relative position of the air outlet and the hair strands shifts, the effective airflow area is further reduced, resulting in airflow only acting on a very small portion of the hair strands close to the barrel. The drooping hair strands, lacking sufficient airflow coverage and guidance, tend to remain naturally drooping, causing the overall style to be loose and poorly adhered, resulting in significant differences in styling effects across different areas of the hair.

[0003] Therefore, there is an urgent need for a new type of shaping tool. Utility Model Content

[0004] In view of this, the present invention aims to provide a styling tool and hair care device to solve the problem that the effective air outlet area of ​​the styling tool will decrease when the user tilts the device.

[0005] In a first aspect, this application proposes a styling tool for hair care, comprising:

[0006] The cylinder has a hollow airflow cavity. The cylinder wall is provided with a plurality of spaced air outlets that are connected to the airflow cavity. The long axis of each air outlet is inclined to the generatrix direction of the cylinder wall, and the air outlet direction of each air outlet is inclined to the circumference of the cylinder wall, so as to guide the airflow discharged from the air outlet to the surface of the cylinder.

[0007] According to the shaping tool of this application, the cylinder is provided with a first air outlet group and a second air outlet group in sequence along the axial direction. Both the first air outlet group and the second air outlet group include a plurality of air outlets. In the first air outlet group, the axial component of the air outlet direction projected on the cylinder wall points to the second air outlet group. In the second air outlet group, the axial component of the air outlet direction projected on the cylinder wall points to the first air outlet group.

[0008] Optionally, in the first air outlet group, along the axial direction of the cylinder from the end away from the second air outlet group to the end near the second air outlet group, the angle between the long axis direction of each air outlet and the generatrix direction of the cylinder wall forms a monotonically decreasing sequence.

[0009] In the second air outlet group, along the axial direction of the cylinder from the end away from the first air outlet group to the end near the first air outlet group, the angle between the long axis direction of each air outlet and the generatrix direction of the cylinder wall forms a monotonically decreasing sequence.

[0010] Optionally, the plurality of air outlets in the first air outlet group and the second air outlet group are arranged in a stepped staggered manner along the generatrix direction of the cylinder wall.

[0011] According to the shaping tool of this application, an air inlet is provided at one axial end of the cylinder, the air inlet is connected to the airflow cavity, and the air outlet direction of the air outlet is axially projected onto the cylinder wall and points to the air inlet.

[0012] According to the shaping tool of this application, a guide channel communicating with the air outlet is provided on the outer wall surface of the cylinder. The bottom of the guide channel is provided with a guide curved surface that is concave towards the inside of the cylinder. In the plane formed by the expansion of the cylinder wall along the generatrix direction, the projection of the extension trajectory of the guide channel is perpendicular to the projection of the long axis of the air outlet.

[0013] Optionally, the end of the flow guide channel near the air outlet is the inlet end, the inlet end of the flow guide channel and the inner surface of the cylinder wall together form the air outlet, and along the radial direction of the cylinder wall, the inlet end of the flow guide channel is located inside the air outlet.

[0014] Optionally, the depth of the concavity of the guide surface relative to the outer surface of the cylinder wall gradually decreases in the direction that gradually moves away from the air outlet.

[0015] According to the shaping tool of this application, the angle between the long axis direction of the air outlet and the generatrix direction of the cylinder wall is 20° to 35°.

[0016] Secondly, this application proposes a hair care device, including the aforementioned styling tool.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The styling tool provided in this application has an air outlet whose long axis forms an angle with the generatrix of the barrel wall. When the user tilts the styling tool, the long axis of the air outlet maintains a higher degree of overlap with the actual direction of action after the tool is tilted during use. This reduces the misalignment of the effective air outlet area with the hair due to angle misalignment, thus preserving a larger effective air outlet area during use. Simultaneously, the tilted long axis ensures that the airflow from the air outlet has components in both the circumferential and generatrix directions of the barrel wall, better covering all areas of the hair and ensuring stable airflow to different sections. The air outlet's direction is tilted circumferentially to the barrel wall, allowing the airflow to more easily follow the curvature of the barrel's outer surface after exiting the outlet, better wrapping the hair and improving the coverage and fit of the airflow, preventing frizz.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] like Figures 1-4 As shown, the styling tool according to an embodiment of this application is used for hair care and includes a cylindrical body with a hollow airflow cavity. The cylindrical body wall 10 is provided with a plurality of spaced air outlets 11, which are connected to the airflow cavity. The long axis direction of each air outlet 11 is inclined to the generatrix direction of the cylindrical body wall 10, and the air outlet direction of each air outlet 11 is inclined to the circumference of the cylindrical body wall 10, so as to guide the airflow discharged from the air outlet 11 to the surface of the cylindrical body.

[0032] The cylindrical body is the main supporting structure of the shaped tool. It is long and cylindrical in shape. The cross-section of the cylindrical body can be circular, elliptical, or polygonal, depending on the needs. Circular and elliptical shapes are more common.

[0033] The axial direction of the cylinder refers to its length direction, that is, the direction of extension from one end of the cylinder to the other.

[0034] The outer wall of the tube can be smooth to reduce hair tangling, or it can have micro-textured patterns to increase friction with the hair and improve the stability of the style.

[0035] One end of the cylinder is closed, and the other end is provided with an air inlet 13, which can prevent airflow from leaking from the end.

[0036] The cylinder wall 10 is a curved surface formed around the axis of the cylinder. Regardless of whether the cross-sectional shape of the cylinder is circular, elliptical, or polygonal, the generatrix direction of the cylinder wall 10 points from one end of its length to the other, and the generatrix direction of the cylinder wall 10 is parallel to the axis of the cylinder. That is, if you take any point on the curved surface of the cylinder wall 10 and draw a straight line along the length of the cylinder (parallel to the axis of the cylinder), the direction of this straight line is the generatrix direction of the cylinder wall 10.

[0037] The cross-section of the cylinder can be circular, elliptical, or polygonal. The circumferential direction of the cylinder wall 10 refers to the circumferential direction surrounding the cylinder axis and along the edge of the cross-section of the cylinder wall 10, while being perpendicular to the generatrix of the cylinder wall 10.

[0038] The function of the airflow cavity is to guide and disperse the airflow delivered to the cylinder from the outside to each air outlet 11. The shape of the airflow cavity matches the shape of the cylinder. For example, the airflow cavity of a cylindrical cylinder is usually set as a coaxially extending cylindrical cavity, and the airflow cavity of an elliptical cylindrical cylinder is usually set as a coaxially extending elliptical cylindrical cavity. The airflow cavity can run through the entire axial direction of the cylinder, that is, extend from one end of the cylinder to the other, or it can be hollowed out only in a local area of ​​the cylinder, such as forming an airflow cavity only in the section where the air outlet 11 is provided.

[0039] For example, one end of the airflow cavity is closed, and the other end is filled with air from the air inlet 13, thereby avoiding airflow diversion.

[0040] Airflow enters the airflow chamber through the air inlet 13 and then flows out of the cylinder through the air outlet 11. The number of airflow chambers can be one or more, which can be set as needed.

[0041] Air outlets 11 are located on the cylinder wall 10 of the tube body and penetrate the cylinder wall 10. When airflow passes through the air outlets 11, it can guide the airflow of the airflow chamber to the outside of the cylinder wall 10, thereby acting on the hair. The air outlets 11 are distributed on the cylinder wall 10 rather than concentrated in one area, and the spacing between adjacent air outlets 11 needs to be set reasonably.

[0042] The shape of the air outlet 11 can usually be set as a long strip, such as a rectangle or a rounded rectangle; or a willow leaf shape, with a tendency to be pointed at both ends and wide in the middle; or an irregular strip; or a circle; or an oval, etc. Usually, the multiple air outlets 11 on the cylinder wall 10 are set with the same shape, but of course they can also be different, depending on the needs.

[0043] For a long strip-shaped air outlet 11, its long axis direction refers to its longest extension direction, that is, the direction from one end of the air outlet 11 to the other end. For example, for a cylindrical body, the long axis direction can extend along the oblique tangent of the cylinder wall 10, and deviate from the generatrix direction of the cylinder wall 10 towards the circumference of the cylinder wall 10.

[0044] For the elliptical air outlet 11, the ellipse is composed of two mutually perpendicular axes of symmetry, the longer of which is called the major axis. The direction of the major axis is the direction from one end of the ellipse along the longest distance to the other end. For example, when the elliptical air outlet 11 is set on the cylindrical wall 10, its major axis is inclined to the generatrix of the cylindrical wall 10, which means that this longest axis of symmetry is neither parallel to nor perpendicular to the generatrix of the cylindrical wall 10, but forms a certain angle.

[0045] For a circular air outlet 11, since all its diameters are of equal length, but its overall shape will tilt towards the generatrix of the cylinder wall 10 or in the circumferential direction, forming a definite arrangement direction, the diameter of which is the direction of the major axis.

[0046] The major axis of each air outlet 11 is inclined to the generatrix direction of the cylinder wall 10, that is, the angle between the major axis of each air outlet 11 and the generatrix direction of the cylinder wall 10 is neither equal to 0° nor equal to 90°.

[0047] The air outlet direction of the air outlet 11 refers to the flow direction of the airflow when it is discharged from the air outlet 11, that is, the flow direction of the airflow from the inner wall side of the cylinder wall 10 to the outer wall side. The air outlet direction of the air outlet 11 is inclined to the circumference of the cylinder wall 10, that is, the air outlet direction is not perpendicular to the circumference of the cylinder wall 10, but inclined to the outer surface of the cylinder wall 10, so that the airflow can flow close to the outer surface of the cylinder wall 10 after being discharged.

[0048] According to the styling tool of this application embodiment, the long axis of the air outlet 11 forms a certain angle with the axial direction of the barrel. When the user tilts the styling tool, the long axis of the air outlet 11 can maintain a higher degree of overlap with the actual direction of action after the styling tool is tilted during use. This reduces the situation where the effective air outlet area is misaligned with the hair due to angular misalignment, thus maintaining a larger effective air outlet area during use. At the same time, the tilted long axis direction makes the airflow from the air outlet 11 have components in both the generatrix direction and the circumferential direction of the barrel wall 10, which can better cover the hair in various areas, so that the hair strands in different positions can be subjected to stable airflow. The air outlet direction of each air outlet 11 is tilted to the circumferential direction of the barrel wall 10, so that the airflow is more likely to flow close to the outer surface of the barrel wall 10 after flowing out of the air outlet 11, which can better wrap the hair, improve the coverage and fit of the airflow on the hair, and prevent the hair from becoming frizzy.

[0049] In actual use, when users wrap hair around the tube wall 10, it is easier to wrap the hair around the middle area of ​​the tube wall 10. However, this results in wasted airflow at both ends, and the airflow in the middle area is prone to being insufficient, requiring a higher level of skill from the user. Therefore, this application proposes a new styling tool to solve the above problems.

[0050] like Figure 1 and Figure 2 As shown, in the shaping tool according to the embodiment of this application, the cylinder is provided with a first air outlet group 20 and a second air outlet group 30 in sequence along the axial direction. Both the first air outlet group 20 and the second air outlet group 30 include a plurality of air outlets 11. In the first air outlet group 20, the axial component of the air outlet direction of the air outlet 11 projected on the cylinder wall 10 points to the second air outlet group 30. In the second air outlet group 30, the axial component of the air outlet direction of the air outlet 11 projected on the cylinder wall 10 points to the first air outlet group 20.

[0051] The air outlets 11 of the first air outlet group 20 are distributed on one side of the axial direction of the second air outlet group 30, and the air outlets 11 of the second air outlet group 30 are distributed on one side of the axial direction of the first air outlet group 20. That is, the first air outlet group 20 and the second air outlet group 30 do not overlap in the axial direction of the cylinder and each has a clearly defined position. In the axial section of the cylinder wall 10 where the first air outlet group 20 is located, multiple air outlets 11 are distributed at intervals along the circumference of the cylinder wall 10. In the axial section of the cylinder wall 10 where the second air outlet group 30 is located, multiple air outlets 11 are distributed at intervals along the circumference of the cylinder wall 10.

[0052] The axial component of the air outlet 11's air outlet direction projected onto the cylinder wall 10 is along the length of the cylinder and is also the generatrix direction of the cylinder wall 10. The projection of the air outlet 11's air outlet direction onto the cylinder wall 10 also includes a circumferential component, that is, along the circumference of the cylinder wall 10.

[0053] In the first air outlet group 20, the axial component of the air outlet direction projected onto the cylinder wall 10 points towards the second air outlet group 30. In the second air outlet group 30, the axial component of the air outlet direction projected onto the cylinder wall 10 points towards the first air outlet group 20. This allows the airflow from both the first and second air outlet groups to be guided towards the center of the cylinder wall 10. The two airflow groups tend to converge towards each other axially, making it easier for the airflow to concentrate in the central area. This ensures that the hair wrapped in the central area receives a stable, continuous, and concentrated airflow, improving styling efficiency and setting stability. Simultaneously, actually wrapping the hair around the center of the styling tool aligns with the user's operating habits, concentrating the airflow energy in that area. This reduces reliance on the user's skill level, matching the airflow range with the actual wrapped area, thus improving the efficiency and effectiveness of styling.

[0054] In this embodiment, the naming of the first air outlet group 20 and the second air outlet group 30 is merely to clearly distinguish the two air outlet groups in different locations in the description, and to facilitate the explanation of their distribution relationship and air outlet direction characteristics. This naming does not imply any difference in structural complexity, functional priority, or importance between the two, nor does it limit their specific arrangement. They can have completely identical structural features, such as having the same number of air outlets 11, the same shape, and the same arrangement, and are named separately only because they are distributed in different areas along the axial direction of the cylinder. They can also present different arrangements according to actual needs, such as the first air outlet group 20 having more air outlets 11 than the second air outlet group 30, or the two having different shapes of air outlets 11. However, these differences are not determined by the names themselves, but are based on specific design requirements.

[0055] In some embodiments, in the first air outlet group 20, along the axial direction of the cylinder from one end away from the second air outlet group 30 to one end near the second air outlet group 30, the angle between the long axis direction of each air outlet 11 and the generatrix direction of the cylinder wall 10 forms a monotonically decreasing sequence.

[0056] In the second air outlet group 30, along the axial direction of the cylinder from the end furthest from the first air outlet group 20 to the end closest to the first air outlet group 20, the angle between the long axis direction of each air outlet 11 and the generatrix direction of the cylinder wall 10 forms a monotonically decreasing sequence.

[0057] The angle between the major axis of each air outlet 11 and the generatrix of the cylinder wall 10 refers to the angle formed between the major axis of the air outlet 11 and the generatrix of the cylinder wall 10. Changes in this angle affect the direction of airflow. These changes can be achieved by adjusting the tilt angle of the air outlet 11 on the cylinder wall 10, without altering the overall dimensions of the air outlet 11 itself. The pattern of angle variation adjusts according to the position of the air outlet 11. At larger angles, the major axis of the air outlet 11 is more circumferentially towards the cylinder wall 10, resulting in a wider coverage area of ​​the airflow around the cylinder wall 10. At smaller angles, the major axis of the air outlet 11 is closer to the generatrix of the cylinder wall 10, leading to stronger convergence of the airflow towards the central region of the cylinder wall 10.

[0058] The monotonically decreasing sequence defines the variation law of the included angles in the first air outlet group 20 and the second air outlet group 30. In the first air outlet group 20, when viewed along the axial direction of the cylinder from the end furthest from the second air outlet group 30 to the end closest, the included angle of any air outlet 11 is no less than the included angle of its adjacent air outlet 11 that is closer to the second air outlet group 30. This means that the farther the air outlet 11 is from the second air outlet group 30, the larger or equal its included angle with the axial direction; the closer the air outlet 11 is, the smaller or equal its included angle, and there is no sudden increase in included angle in the entire sequence. The same law applies to the second air outlet group 30. When viewed along the axial direction of the cylinder from the end furthest from the first air outlet group 20 to the end closest, the included angle of each air outlet 11 is no less than the included angle of its adjacent air outlet 11 that is closer to the first air outlet group 20. This allows the airflow to transition smoothly and stably as it is guided and converged regularly from the end of the cylinder to the middle, avoiding turbulence.

[0059] According to the styling tool of this application embodiment, the air outlet 11 far from the middle area is more biased towards the circumference of the barrel wall 10 in the long axis direction, while the air outlet 11 closer to the middle area is closer to the generatrix direction of the barrel wall 10 in the long axis direction. This can better concentrate the airflow towards the middle area, so that the hair is stably kept in the middle area and the styling efficiency of the hair in the middle area is improved.

[0060] like Figure 7 As shown, in some embodiments, the plurality of air outlets 11 in the first air outlet group 20 and the second air outlet group 30 are arranged in a stepped staggered manner along the generatrix direction of the cylinder wall 10.

[0061] The stepped staggered arrangement refers to the distribution of multiple air outlets 11 within an air outlet group (first air outlet group 20 or second air outlet group 30) along the generatrix direction of the cylinder wall 10, where the axial positions of adjacent air outlets 11 are staggered sequentially, forming a step-like distribution. Adjacent air outlets 11 cannot be arranged in a row along the generatrix direction of the cylinder wall 10; adjacent air outlets 11 are offset both along the generatrix direction and circumferentially, meaning that each air outlet 11 is spatially positioned diagonally above or below the preceding air outlet 11.

[0062] The adjacent air outlets 11 are uniformly offset in the generatrix direction and circumferential direction of the cylinder wall 10, or the offset amplitude gradually decreases as it approaches the middle of the cylinder wall 10, which can be set as needed.

[0063] According to the styling tool of this application embodiment, the multiple air outlets 11 in the first air outlet group 20 and the second air outlet group 30 are arranged in a stepped staggered manner along the generatrix direction of the cylinder wall 10. The stepped staggered arrangement makes the airflow distribution of adjacent air outlets 11 more compact, forming a more dispersed and dense airflow network on the surface of the cylinder wall 10. This avoids concentrated airflow superposition, allowing the hair wrapped around the styling tool to be subjected to a uniform, dense, and gentle airflow, reducing airflow blind spots, improving the coverage of the hair strands, and allowing heat or styling substances (such as negative ions) to act more evenly on each hair strand, improving the consistency of the overall styling. In addition, when this dispersed airflow acts on the hair strands, it does not form a concentrated impact force, but rather wraps the hair strands in a gentler way, reducing the lifting of hair cuticles caused by strong airflow impact, thereby avoiding frizzy hair.

[0064] In actual use, since users usually hold the styling tool at one end, the hair tends to fall downwards due to gravity. This causes differences in hair volume in different areas and uneven airflow, which weakens the durability of the style. Therefore, this application proposes a new styling tool.

[0065] like Figure 6 As shown, in the shaping tool according to the embodiment of this application, an air inlet 13 is provided at one end of the cylinder in the axial direction. The air inlet 13 is connected to the airflow cavity, and the axial component of the air outlet 11 projected onto the cylinder wall 10 points to the air inlet 13.

[0066] The air outlet 11's airflow direction projected onto the cylinder wall 10 can be decomposed into axial and circumferential components. The intensity of the axial component of different air outlets 11 can be the same or different. For example, the axial component of the air outlet 11 near the air inlet 13 is weaker, while the axial component of the air outlet 11 far from the air inlet 13 is stronger, which can make the airflow in the area near the air inlet 13 more gentle.

[0067] The axial component of the air outlet 11's air outlet direction projected onto the cylinder wall 10 points towards the air inlet 13, ensuring that the airflow on the surface of the cylinder wall 10 tends to converge towards the air inlet 13.

[0068] The styling tool has an air inlet 13 at one end, which connects to a handle. A fan assembly is located in the handle. When the user grips the handle, the end of the barrel with the air inlet 13 faces downwards. Due to gravity, the hair tends to fall downwards away from the gripping side, resulting in uneven hair distribution in different areas, with hair clustered near the bottom and sparse at the top. The axial component of the air outlet 11's projection onto the barrel wall 10 points towards the air inlet 13, i.e., in the same direction as the user's gripping side. This allows the airflow to better conform to the hair distribution in the lower area, ensuring that the hair clustered at the bottom is fully enveloped by the airflow, allowing the lower hair to be evenly stressed and styled, improving the integrity and stability of the style.

[0069] In actual use, the air outlet 11 alone has limited guiding effect on the airflow. The airflow after exiting the air outlet 11 tends to decay quickly. Especially when hair is wrapped around the tube wall 10, the dispersed airflow cannot fully penetrate the gaps between the hair strands. The airflow is too strong in the local area near the air outlet 11, while it is insufficiently covered in the area further away in the thickness direction. At the same time, the airflow that is directly discharged is also prone to impacting the hair strands and causing them to become frizzy due to the lack of guidance. Therefore, this application proposes a new type of styling tool.

[0070] like Figure 1 , Figure 3 as well as Figure 6 As shown, in the shaping tool according to the embodiment of this application, a guide channel 12 communicating with the air outlet 11 is provided on the outer wall surface of the cylinder. The bottom of the guide channel 12 is provided with a guide curved surface that is concave towards the inside of the cylinder. In the plane formed by the cylinder wall 10 unfolding along the generatrix direction, the projection of the extension trajectory of the guide channel 12 is perpendicular to the projection of the long axis of the air outlet 11.

[0071] The outer wall of the tube body is the outer surface of the tube wall 10, which is the surface that directly contacts or is in close contact with the hair. Its shape is usually adapted to the shape of the airflow cavity inside the tube. The outer surface of the tube wall 10 can be cylindrical or slightly curved. Alternatively, it can have fine textures to enhance the fit with the hair.

[0072] like Figure 3 As shown, the guide channel 12 is a groove-shaped structure formed on the outer surface of the cylinder wall 10, which is directly connected to the air outlet 11 and is used to receive and guide the airflow discharged from the air outlet 11. It is generally elongated; or it is wide at one end near the air outlet 11 and narrow at the other end away from the air outlet 11, and it is integrally formed with the cylinder wall 10. Figure 5 The inner wall surface of the cylinder wall 10 opposite to the flow channel 12 is shown.

[0073] Within the plane formed by unfolding the cylinder wall 10 along its generatrix direction—that is, by cutting and flattening the cylinder wall 10 along its generatrix direction—the length of this plane corresponds to the axial direction of the cylinder or the generatrix direction of the cylinder wall 10, and the width of this plane corresponds to the circumferential direction of the cylinder wall 10. All structures on the cylinder wall 10 have a corresponding planar projection on this plane.

[0074] The projection of the extension trajectory of the guide channel 12 is the path along which the guide channel 12 extends along the curved surface of the cylinder wall 10, forming a corresponding planar line on the plane. The projection of the major axis of the air outlet 11 is the corresponding line formed by the major axis of the air outlet 11 on the plane. These two lines are perpendicular to each other in the plane.

[0075] The concave guide surface not only directs the airflow but also forms an arc-shaped connection with the cylinder wall 10, facilitating demolding or part removal and reducing stress concentration. It also makes it less likely to scratch the user.

[0076] According to the styling tool of this application embodiment, in the plane formed by the expansion of the cylindrical wall 10 along the generatrix direction, the projection of the extension trajectory of the guide channel 12 is perpendicular to the projection of the long axis of the air outlet 11. The guide channel 12 can directionally guide the airflow flowing out of the air outlet 11. Even when faced with local airflow disturbance caused by hair tangling, it can maintain directional flow, maintain concentrated flow speed and force, and can penetrate the gaps between hair strands more efficiently, so that the hair strands are evenly stressed, avoiding insufficient local effect caused by airflow dispersion, and ultimately improving the accuracy and consistency of styling.

[0077] like Figure 3 and Figure 5 As shown, in some embodiments, the end of the flow channel 12 near the air outlet 11 is the inlet end. The inlet end of the flow channel 12 and the inner surface of the cylinder wall 10 together form the air outlet 11, and along the radial direction of the cylinder wall 10, the inlet end of the flow channel 12 is located inside the air outlet 11.

[0078] The end of the flow channel 12 closest to the air outlet 11 is the inlet end, which refers to the starting part of the flow channel 12 that is directly connected to the air outlet 11. The inlet end is usually open and recessed towards the axis of the cylinder, and is spaced from the inner surface of the cylinder wall 10 to form the air outlet 11.

[0079] The radial direction of the cylinder wall 10 refers to the direction along the inner surface of the cylinder wall 10 to the outer surface of the cylinder wall 10, or the direction from the outer surface of the cylinder wall 10 to the inner surface of the cylinder wall 10, that is, the radial direction perpendicular to the cylinder axis.

[0080] The inner surface of the cylinder wall 10 forming the air outlet 11 has the same curvature as other areas of the cylinder wall 10. This allows the cylinder wall 10 to continue its own contour without protruding or sinking on the original contour of the cylinder wall 10, simplifying the mold structure and reducing production difficulty.

[0081] The air outlet 11 is formed by the inner surface of the cylinder wall 10 and the inlet end of the guide channel 12, eliminating the need for complex boundary components and reducing mold complexity. The guide channel 12 and the cylinder wall 10 are integrally formed, either by injection molding or by metal stamping. Furthermore, along the radial direction of the cylinder wall 10, the inlet end of the guide channel 12 is radially opposite to the inner surface of the cylinder wall 10, and the inlet end is located inside the air outlet 11. This makes core placement during injection molding and mold alignment during metal stamping easier to process, avoiding molding dead zones.

[0082] For example, the flow channel 12, the air outlet 11 and the cylinder wall 10 can be integrally formed by injection molding. During molding, the air outlet 11 needs to be formed by core processing. Therefore, the end near the air outlet 11 is wider, while the end away from the air outlet 11 can be naturally narrowed, without the need to reserve a core position.

[0083] For example, the cylinder wall 10 can be processed into a flow channel 12 and an air outlet 11 by metal stamping after forming.

[0084] like Figure 5 As shown, in some embodiments, the depth of the concavity of the guide surface relative to the outer surface of the cylinder wall 10 gradually decreases in the direction that gradually moves away from the air outlet 11.

[0085] The depth of the concavity of the guide surface relative to the outer surface of the cylinder wall 10 is the degree to which the guide surface is concave toward the central axis of the cylinder wall 10. The greater the depth, the more obvious the concavity of the guide surface, and the greater the extent of concavity toward the central axis of the cylinder wall 10.

[0086] The guide surface is an inwardly concave arc shape, which conforms to the flow characteristics of the airflow, allowing the airflow to flow smoothly along the guide surface and reducing impact. The guide surface can be a single continuous arc or a combination of multiple arcs with different curvatures, ensuring that the overall guide surface is smooth and without sharp angles.

[0087] In this embodiment, when the air outlet 11 is close, the concave depth of the guide surface relative to the outer surface of the cylinder wall 10 is larger, that is, the concavity is more obvious. As it moves away from the air outlet 11, the depth of the surface gradually decreases and the concavity becomes gentler. This allows the airflow direction to be deflected better and guided to the outer surface of the cylinder wall 10 better, enhancing the fit of the airflow to the outer surface of the cylinder wall 10, and making the heat or wind more efficient on the hair wrapped around the cylinder wall 10.

[0088] According to the embodiment of this application, the angle between the major axis of the air outlet 11 and the generatrix of the cylinder wall 10 is 20° to 35°.

[0089] In most cases, the hair will spirally wrap around the outer surface of the tube wall 10 along the generatrix direction. The angle between the long axis of the air outlet 11 and the generatrix direction of the tube wall 10 is 20° to 35°, which can better adapt to the winding angle of the hair strands, allowing the airflow to blow out in a direction closer to the direction of the hair strands, penetrate the wrapped hair strands more efficiently, and cover more hair strands from the inner layer to the outer layer.

[0090] The included angle can be 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, and 35°, etc.

[0091] The hair care device according to the embodiments of this application includes the styling tool described above.

[0092] The hair care device according to the embodiments of this application includes the above-mentioned styling tools and has all the above-mentioned technical effects, which will not be repeated here.

[0093] The hair care device also includes a handle. The handle has a proximal end and a distal end, with an air inlet at the proximal end. The handle includes a fan assembly and a motor assembly; the styling tool engages with the distal end of the handle.

[0094] According to the embodiments of this application, the hair care device has a handle and styling tool that can be quickly assembled and disassembled by a snap-fit ​​connection. When the motor component drives the fan component to generate airflow, the airflow enters the inner cavity of the handle through the air inlet at the near end of the handle and enters the airflow chamber of the barrel through the air inlet 13, and flows out through the air outlet 11. During this process, due to the stable connection between the handle and the barrel, airflow leakage or structural noise caused by the vibration of the fan component or motor component can be avoided. At the same time, by setting the styling tool and the handle to a snap-fit ​​connection, the standardized design can support the compatibility of different accessories. Users can quickly switch accessories according to different hairstyle needs, thereby improving the efficiency of hair care and the operating experience.
