Detailed Implementation

[0031] 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.

[0032] 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.

[0033] 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.

[0034] like Figures 3-6 As shown, the styling accessory according to an embodiment of this application includes a body 10, which has a first end E and a second end F. The first end E of the body 10 is also provided with a base 20 and a cover plate 30. A first mating member 21 is provided on the base 20, and a second mating member 13 is provided on the body 10. The first mating member 21 and the second mating member 13 are rotatably engaged. The cover plate 30 is snapped into the base 20 and the body 10, and a stop member 31 is provided on the cover plate 30. The stop member 31 is snapped into the first mating member 21 and / or the second mating member 13.

[0035] In detail, when the base 20 and the body 10 are assembled, the first mating part 21 and the second mating part 13 form a rotatable engagement. This allows the second mating part 13 to be axially inserted into the first mating part 21 when rotated to a certain angle. After rotating through a certain angle, the base 20 and the body 10 are positioned axially. Then, the cover plate 30 is inserted, causing the stop member 31 to engage with at least one of the first mating parts 21 and the second mating part 13, preventing further rotation of the first mating parts 21 and the second mating part 13. This circumferentially limits the movement of at least one of the first mating parts 21 and the second mating part 13, thus achieving circumferential positioning of the base 20 and the body 10 and ensuring a stable connection between them. During disassembly, simply remove the cover plate 30. The stop member 31 disengages from either the first mating part 21 or the second mating part 13, and the base 20 and the body 10, no longer restrained by the stop member 31, rotate circumferentially to disengage.

[0036] The body 10 is a hollow tube, and its radial cross-section can be circular, elliptical, or polygonal. The wall thickness of the body 10 can be uniformly consistent throughout, or it can be gradually varied according to a specific pattern.

[0037] The first end E and the second end F of the body 10 can be opposite each other along the extension axis of the body 10 itself, or they can be opposite each other along the radial direction of the body 10. The extension axis of the body 10 itself can be a straight line or a bent line. For example, the body 10 is L-shaped, U-shaped or curved, and the first end E and the second end F are opposite each other along the extension axis of the body 10, and the first end E and the second end F intersect at a certain angle.

[0038] The main body 10 includes a first air outlet 11 and a hollow cavity. The base 20 defines an air inlet. The air inlet, the cavity, and the first air outlet 11 are sequentially connected. The first air outlet 11 of the main body 10 and the hollow cavity form an airflow channel to guide the airflow introduced by the air inlet of the base 20 to the hair care area. The styling accessory can have functions such as drying and heating. For example, when the styling accessory has a drying function, a fan assembly and a motor assembly can be installed in the cavity of the main body 10, or an additional handle can be provided. The handle is snapped into the base 20, and the fan assembly and motor assembly are installed in the handle. When the styling accessory also needs to have a heating function, a heating assembly can be directly installed in the cavity of the main body 10. This can heat the airflow in the cavity so that the airflow blown out from the first air outlet 11 has the required temperature.

[0039] The heating component heats the airflow delivered by the fan component within the cavity of the main body 10, forming hot air at a suitable temperature. When the hot air acts on the hair through the first air outlet 11 on the cylinder wall, the heat can accelerate the evaporation of hair moisture to achieve rapid drying. At the same time, the temperature changes the state of the hair cuticles. Combined with the airflow direction and the support provided to the hair by different curvature radii of the main body 10, the hair is styled in a thermoplastic state, achieving different styling effects from natural low volume to significantly high volume. Furthermore, the uniform heating characteristics of the heating component can avoid local overheating and damage to the hair, improving the safety and stability of the styling effect.

[0040] In some embodiments, a heating component is disposed in the middle of the cavity of the body 10 or in the area near the first air outlet 11. The heating component can be a heating element such as a metal heating wire or a ceramic heating plate, and is distributed in a ring, spiral, or grid pattern. The outer side of the heating component can also be covered with a guide grille to allow airflow to pass evenly through the heating area and avoid local overheating. The heating component is connected to the control circuit in the handle, and the heating level can be adjusted by buttons or a touch panel on the side of the handle.

[0041] In some embodiments, the extension axis of the handle coincides with the extension axis of the body 10; in some embodiments, the extension axis of the handle is perpendicular to the extension axis of the body 10; and in some embodiments, the angle between the extension axis of the handle and the extension axis of the body 10 is an acute angle.

[0042] The main body 10 is provided with a first air outlet 11, which can be located at the second end F or on the cylindrical wall of the main body 10. There can be one or more first air outlets 11. By setting different shapes of the first air outlets 11, the airflow pattern can be adjusted. For example, when there is only one first air outlet 11, its shape can be circular or a flat strip; when there are multiple first air outlets 11, they can be an array of circular holes or an array of strip holes. Based on the different densities of the first air outlets 11 in different areas, the airflow speed, direction, and coverage area can be adjusted, thereby achieving different hair care functions.

[0043] The base 20 is disc-shaped, elliptical, or irregularly shaped, with a central air inlet to allow airflow into the cavity of the main body 10. The main plane of the base 20 is perpendicular to the axis of the main body 10, and the axis of the air inlet coincides with or is parallel to the axis of the main body 10. The base 20 is used to engage with the handle, guiding the airflow output from the fan assembly of the handle into the cavity through the air inlet and out through the first air outlet 11. The shape of the air inlet can be circular, elliptical, square, or other shapes, with a diameter slightly smaller than the air outlet of the handle, which facilitates the even distribution of airflow output from the handle into the cavity.

[0044] The first mating part 21 can be an arc-shaped groove or an annular groove.

[0045] The cover plate 30 is disc-shaped, elliptical, rectangular, etc.; the circumferential edge of the cover plate 30 can be provided with a snap fastener to engage with the outer periphery of the base 20 or the body 10. The stop member 31 can engage with the first mating member 21, or with the second mating member 13, or simultaneously with both the first mating member 21 and the second mating member 13. The stop member 31 can have slight elasticity, so that it can undergo slight deformation during engagement with the first mating member 21 or the second mating member 13 to accommodate angular deviations, making installation smoother. The stop member 31 extends toward the first mating member 21 or the second mating member 13. For example, the stop member 31 can be cylindrical, triangular prism-shaped, or a hook-shaped protrusion. At least one of the first mating member 21 and the second mating member 13 is provided with a groove that engages with the stop member 31. The stop member 31 extends from the inside of the cover plate 30 toward the first mating member 21 or the second mating member 13, and its axis is parallel to or at a certain angle to the axis of the body 10.

[0046] When the stop member 31 engages with the first mating member 21, for example, multiple arc-shaped grooves are provided on the inner circumference of the base 20, and the multiple arc-shaped grooves are distributed at intervals along the circumferential direction of the base 20. During assembly, after the second mating member 13 is inserted into the arc-shaped groove, the cover plate 30 is moved to a predetermined position to assemble with the base 20. The stop member 31 is aligned with the engagement position of the arc-shaped groove, and elastically deforms and presses in to achieve engagement, thereby preventing the second mating member 13 from rotating in the opposite direction and coming out.

[0047] When the stop member 31 engages with the second mating member 13, for example, multiple arc-shaped grooves are provided on the inner circumference of the base 20, and the multiple arc-shaped grooves are distributed at intervals along the circumferential direction of the base 20. During assembly, after the second mating member 13 is inserted into the arc-shaped groove, the cover plate 30 is moved to a predetermined position to assemble with the base 20. The stop member 31 is aligned with the first engaging groove 131 of the second mating member 13, and elastically deforms and presses in to achieve engagement, thereby preventing the second mating member 13 from rotating in the opposite direction and coming out.

[0048] When the stop member 31 engages with the second mating member 13 and the first mating member 21 simultaneously, for example, multiple arc-shaped grooves are provided on the inner circumference of the base 20, and the multiple arc-shaped grooves are distributed at intervals along the circumferential direction of the base 20. During assembly, after the second mating member 13 is inserted into the arc-shaped groove, the cover plate 30 is moved to a predetermined position to assemble with the base 20. The stop member 31 is inserted into the engagement position of the first mating member 21 and the second mating member 13, and elastic deformation is pressed in to achieve engagement, thereby preventing the second mating member 13 from rotating in the opposite direction and coming out.

[0049] The first mating part 21 can be an arc-shaped groove, an annular groove, or a spiral guide groove, extending along the inner circumference of the base 20 or along the outer circumference of the base 20. The second mating part 13 can be an arc-shaped boss, an annular flange, or a spiral guide rib, extending along the outer circumference of the body 10 or along the inner circumference of the body 10. It can be understood that when the first mating part 21 is located on the inner circumference of the base 20, the second mating part 13 is located on the outer circumference of the body 10, and when the first mating part 21 is located on the outer circumference of the base 20, the second mating part 13 is located on the inner circumference of the body 10.

[0050] In one specific embodiment, both the first mating member 21 and the second mating member 13 extend circumferentially along the axis of the body 10, forming a ring-shaped or segmented mating structure. That is, multiple sets of first mating members 21 and second mating members 13 can be provided circumferentially. For example, the circumferential angle corresponding to adjacent first mating members 21 is 120°, thereby improving the stability of the connection between the body 10 and the base 20.

[0051] According to the embodiments of this application, the styling accessories can be disassembled or assembled by hand without the need for additional tools or accessories, which simplifies the disassembly and assembly steps. In addition, the assembly contact area between the body 10 and the base 20 is large, which can ensure the stability of each component in a high-frequency vibration working environment. While ensuring structural strength, it significantly improves the convenience of disassembly and assembly.

[0052] like Figures 3-6 As shown, in the styling accessory according to the embodiment of this application, the cover plate 30 is disposed on the side of the base 20 away from the main body 10, the base 20 is provided with a relief opening 24, the stop member 31 protrudes from the cover plate 30 and extends into the relief opening 24 toward the base 20, and is engaged with the second mating member 13.

[0053] After the base 20 and the body 10 are rotatably connected via the first mating member 21 and the second mating member 13, the cover plate 30 is aligned with the top surface of the base 20, and the stop member 31 of the cover plate 30 is aligned with the clearance opening 24 of the base 20. The cover plate 30 is then pressed vertically. At this time, the cover plate passes through the clearance opening 24 and engages with the second mating member 13 of the body 10, restricting the relative rotation between the base 20 and the body 10, thus achieving circumferential locking.

[0054] In the above embodiments, the clearance opening 24 can be fan-shaped, circular, elliptical, or partially annular.

[0055] In some embodiments, the stop member 31 is a hook-shaped protrusion, and the second mating member 13 is provided with a locking groove, which can produce slight deformation. For example, it is made of plastic. The base 20 is provided with a relief opening 24. The stop member 31 passes through the relief opening 24 and elastically engages in the locking groove on the second mating member 13. The locking force generated by the elastic deformation locks the relative position of the base 20 and the body 10 in the circumferential direction.

[0056] According to the styling accessory of the present application embodiment, the locking force between the stop member 31 and the second mating member 13 completely locks the first mating member 21 and the second mating member 13, preventing the base 20 from rotating relative to the body 10, and can maintain a fixed connection even when subjected to high-frequency vibration of the hair dryer or the impact of airflow.

[0057] like Figure 5 , Figure 6 as well as Figure 9 As shown, in some embodiments, the base 20 further includes a receiving cavity 22, an avoidance opening 24 is disposed within the receiving cavity 22, and a cover plate 30 is embedded in the receiving cavity 22. When the base 20 has an air inlet, the receiving cavity 22 and the air inlet are spaced apart.

[0058] The receiving cavity 22 may be arranged around the outer periphery of the air inlet, concentrically or eccentrically distributed with the air inlet, or located on one side of the air inlet. For example, the cavity wall of the receiving cavity 22 extends vertically into the base 20. An abutment 24 is provided near the air inlet in the cavity. The shape of the abutment 24 matches the stop member 31 so that the stop member 31 can pass through. The shape of the abutment 24 can also guide the stop member 31, guiding it to align with the engaging groove on the second mating member 13.

[0059] According to the embodiment of this application, the accommodating cavity 22 provides an embedding space for the cover plate 30, making the overall structure of the styling accessory compact and the surface flat, reducing the possibility of dust and foreign objects entering the connecting parts. Moreover, the accommodating cavity 22 can pre-position the cover plate 30 when it is assembled with the base 20 and the body 10, ensuring that the stop member 31 of the cover plate 30 and the second mating member 13 of the body 10 can accurately align, shortening the observation and alignment time and reducing the alignment difficulty.

[0060] According to the styling accessories of this application embodiment, the first mating part 21 includes an arc-shaped groove disposed on the inner periphery of the base 20, and the second mating part 13 includes an arc-shaped boss disposed on the outer wall of the first end E of the body 10, the arc-shaped boss being embedded in the arc-shaped groove.

[0061] In this embodiment, the arc-shaped groove extends along the inner circumference of the base 20 to form one or more continuous arc-shaped paths. The radial section of the arc-shaped groove is perpendicular to its extension direction. The radial section can be semi-circular, rectangular, trapezoidal or other shapes. The arc-shaped groove allows the arc-shaped boss to slide circumferentially within it. The arc-shaped groove can restrict the separation of the body 10 and the base 20 in the axial direction and can guide the relative rotation of the two through the arc-shaped contour, thereby achieving rapid alignment.

[0062] The arc-shaped boss is adapted to the arc-shaped groove. For example, when the radial cross-section of the arc-shaped groove is semi-circular, the radial cross-section of the arc-shaped boss is also semi-circular; when the radial cross-section of the arc-shaped groove is trapezoidal, the radial cross-section of the arc-shaped boss is also trapezoidal; when the radial cross-section of the arc-shaped groove is rectangular, the radial cross-section of the arc-shaped groove is also rectangular, and so on. The arc-shaped boss extends circumferentially on the outer wall of the first end E of the body 10. The length of the arc-shaped boss is equal to or slightly shorter than the length of the arc-shaped groove to reserve space for rotation. After the arc-shaped boss is embedded in the arc-shaped groove, it achieves axial limiting by contacting the groove wall of the arc-shaped groove to prevent the body 10 from separating from the base 20. A stop surface can be provided at the end of the arc-shaped boss to make it more stable when in contact with the deepest part of the arc-shaped groove.

[0063] For example, the sidewalls of the arc-shaped groove along both sides of the axial direction, one sidewall forms a continuous arc-shaped path along the circumferential direction of the inner circumference of the base 20, and the other sidewall forms an intermittent arc-shaped path. The arc-shaped boss is formed in multiple segments along the circumferential direction of the body 10. The multiple arc-shaped boss segments are engaged between the intervals between two adjacent sidewall segments and rotate into place along the sidewall of the arc-shaped groove.

[0064] For example, raised points can also be provided in the arc-shaped groove to provide tactile feedback when the arc-shaped boss rotates into place, making it easier for the user to perceive whether the arc-shaped boss has rotated into place.

[0065] According to the styling accessory of this application embodiment, the arc-shaped boss and the arc-shaped groove can provide each other with limiting and guiding contours, allowing the base 20 and the body 10 to be rotated slightly after axial insertion, so that the two can be quickly aligned. After alignment, a slight rotation is performed to assemble the two into place, for example, so that the arc-shaped boss is embedded in the deepest position of the arc-shaped groove in the circumferential direction, thereby preventing the two from separating. After the arc-shaped boss is embedded in the groove, a surface contact seal is formed through arc surface contact, which is more suitable for high vibration application scenarios when the hair dryer is working.

[0066] like Figure 4 As shown, in some embodiments, the first mating member 21 further includes an inlet and an anti-detachment part 23, which are arranged opposite to each other along the axial direction of the base 20. The inlet communicates with the arc-shaped groove and allows the arc-shaped boss to pass through. The anti-detachment part 23 is located on the side of the arc-shaped boss away from the second end F.

[0067] The width of the inlet is greater than or slightly greater than the length of the arc-shaped boss in the circumferential direction, which facilitates the insertion of the arc-shaped boss. The anti-detachment part 23 is set opposite to the inlet and extends towards the central axis of the base 20. After the arc-shaped boss slides into the arc-shaped groove, the anti-detachment part 23 is located on the side of the arc-shaped boss away from the second end F. In this way, after the arc-shaped boss enters the inlet and moves into place, the anti-detachment part 23 can prevent the arc-shaped boss from continuing to move outward, ensuring that the arc-shaped boss can be accurately guided to be aligned with the arc-shaped groove. The anti-detachment part 23 can limit the axial position between the body 10 and the base 20.

[0068] The anti-detachment part 23 can be connected to the solid structure that defines the arc-shaped groove, which can enhance the overall rigidity; or the anti-detachment part 23 can be spaced apart from the solid structure that defines the arc-shaped groove, so as to reduce the use of raw materials while meeting the structural strength requirements.

[0069] For example, at least one side of the inlet in the circumferential direction may be provided with an inclined guide surface to guide the anti-detachment part 23 into the arc-shaped groove.

[0070] For example, the inlet can be provided with multiple steps along the axial direction, and the width of each step gradually decreases from the outside to the inside along the circumferential direction. For example, the arc-shaped boss can first slide into the first step, then slide into the second step, and finally slide to the deepest part of the arc-shaped groove.

[0071] According to the styling accessory of this application embodiment, during assembly, the end face of the first end E of the body 10 abuts against the end face of the base 20 near the first end E, thereby limiting the axial position of the body 10 and the base 20. After the arc-shaped boss moves into place along the inlet, the anti-detachment part 23 can prevent the arc-shaped boss from moving outward, ensuring that the arc-shaped boss can be accurately guided to align with the arc-shaped groove. At this time, there is no need to observe the alignment of the arc-shaped boss and the arc-shaped groove. It is only necessary to rotate one of them so that the arc-shaped boss can be inserted into the arc-shaped groove along the guide of the anti-detachment part 23. You can feel whether the two are assembled in place by hand, thereby further limiting the axial position of the base 20 and the body 10 and preventing them from separating in the axial direction. This achieves both the convenience of assembly and disassembly and the reliability of the connection.

[0072] like Figure 3 , Figure 7 and Figure 8 As shown, according to the embodiment of this application, the body 10 is covered with a shell 40, the shell 40 abuts against the side of the base 20 near the body 10, and the shell 40 is provided with a second air outlet 41 communicating with the first air outlet 11, and the first air outlet 11 corresponds to at least one second air outlet 41.

[0073] The outer shell 40 is tubular or sleeve-shaped and is fitted onto the outside of the main body 10. The radial cross-sectional shape of the outer shell 40 is adapted to the main body 10. For example, when the radial cross-sectional shape of the main body 10 is circular, the radial cross-sectional shape of the outer shell 40 is circular; when the radial cross-sectional shape of the main body 10 is elliptical, the radial cross-sectional shape of the outer shell 40 is elliptical; when the radial cross-sectional shape of the main body 10 is olive-shaped, the radial cross-sectional shape of the outer shell 40 is also olive-shaped, etc.

[0074] The outer casing 40 extends along the axial direction of the body 10 and can be coaxial with the body 10 or have a slight angle to ensure that the airflow can be smoothly introduced from the first air outlet 11 into the second air outlet 41.

[0075] The shape of the second air outlet 41 can be oblong, elongated, circular, or oval. The number of second air outlets 41 can be one or more. When multiple second air outlets 41 are provided on the outer casing 40, different numbers or shapes of second air outlets 41 can be provided in different areas according to the specific shape of the outer casing 40 to meet different design requirements.

[0076] For example, the cylindrical wall of the outer shell 40 is formed with a first functional end and a second functional end in the radial direction relative to the extension direction of the outer shell 40, and the outer contour shapes of the first functional end and the second functional end are different. The outer contour shape refers to the edge contour line of the radial cross-section of the outer shell 40, such as a semi-circular, semi-elliptical, or irregular curved surface shape, which can be concave towards the body 10 or convex away from the body 10. When concave, it can be used to style hair into curls, and when convex, it can allow airflow to be closer to the hair roots, generating a stronger lifting ability for the hair, which is suitable for creating a fluffy hair root and high crown effect.

[0077] The first functional end and the second functional end are located in different regions of the shell wall of the outer shell 40, which can be different sectors along the circumferential direction of the outer shell 40. For example, the outer contour of the first functional end is a transition structure with a specific curvature change, and its shape in the radial cross-section is similar to an elliptical arc or a parabolic arc. The outer contour of the second functional end can be a structure with no change in curvature, and its shape in the radial cross-section is similar to a semi-circular arc, or a surface composed of different curvature radii, for example, some areas are locally convex and some areas are locally concave. The first functional end and the second functional end do not have obvious dividing lines, steps or abrupt transitions in appearance or structure on the circumferential contour of the outer shell 40, but are connected in a smooth and continuous manner to form an integrated outer contour shape.

[0078] The outer contour of the first functional end is a flat elliptical arc surface, with its major axis and minor axis both located within the radial cross-section of the outer casing 40, and the length of the major axis being greater than the length of the minor axis. The first functional end is provided with multiple second air outlets 41, and the axis of each second air outlet 41 is consistent with the normal direction of the ellipse. The outer contour of the second functional end is a semi-circular arc surface, and the second functional end is provided with multiple second air outlets 41, and the axis of each second air outlet 41 is consistent with the normal direction of the semi-circular arc surface.

[0079] The first and second functional ends can switch functions by gradually changing the curvature of the outer shell 40. Users do not need to deliberately distinguish the boundaries when using it. They can adaptably rotate the entire styling accessory to adjust the angle of the outer shell 40 when supporting the hair, thus making it suitable for different people, hair types and head shapes.

[0080] The outer casing 40 has an asymmetrical olive-shaped radial cross-section, with a smaller first functional end and a larger second functional end. This design allows the first functional end to support the hair at a small angle, resulting in a low support height and a natural, low-volume effect. Conversely, the second functional end provides support at a large angle, resulting in a high-volume effect. During use, no replacement parts are needed; simply rotating the outer casing 40 changes the height at which it supports the hair, allowing for better adaptation to the user's needs.

[0081] The outer casing 40 is also provided with a bristle mounting part, which is equipped with bristles. The cross-sectional area of ​​the second air outlet 41 provided on the first functional end is different from that of the second air outlet 41 provided on the second functional end. The bristles can comb the hair strands and separate them when in contact with the hair, so that the airflow of the second air outlet 41 can act evenly on each individual hair, avoiding tangling and improving the contact efficiency with the airflow. Since the second functional end has a larger surface area, the number of second air outlets 41 provided on the second functional end is greater than the number of second air outlets 41 provided on the first functional end, making the air outlet area of ​​the second functional end larger than that of the first functional end.

[0082] Because the radial cross-section of the outer shell 40 is a continuous asymmetrical olive shape, the curvature of both sides of the long axis changes from the first functional end to the second functional end when the outer shell 40 rotates. Therefore, when styling, it is not limited to styling only at the first or second functional end. Rather, based on the configuration of the first and second functional ends, the outer shell 40 can be rotated arbitrarily to fit any area of ​​its circumference against the hair. For example, there is a connecting wall between the first and second functional ends, and the radius of curvature of the connecting wall is between that of the first and second functional ends, which can provide moderate support for the hair and achieve a natural, fluffy effect. Users only need to rotate the outer shell 40 with one hand to dynamically adjust the support height without changing parts or stopping the operation, maintaining smooth styling throughout.

[0083] The first air outlet 11 and the second air outlet 41 can correspond one-to-one, or one first air outlet 11 can correspond to multiple second air outlets 41.

[0084] The outer casing 40 abuts against the side of the base 20 closest to the main body 10. The base 20 can restrict the axial position of the outer casing 40 and restrict the axial movement of the outer casing 40, ensuring that the second air outlet 41 always corresponds to the first air outlet 11 and avoids offset.

[0085] For example, the base 20 is provided with an annular groove on the side near the body 10, and the stop end of the housing 40 is a corresponding annular flange. The annular flange is inserted into the annular groove to form a mechanical limit, and at the same time, it can help to seal between the housing 40 and the base 20.

[0086] For example, the end face of the stop end of the housing 40 is a flat annular surface. During assembly, the housing 40 slides in from the second end F of the body 10, or from the first end E of the body 10, until the stop end of the housing 40 abuts against the base 20. For example, if the second end F of the body 10 is provided with an integrally formed limiting boss, the housing 40 slides in from the first end E of the body 10. If the second end F of the body 10 is provided with a top button 50 that is separately formed from the body 10, the housing 40 can slide in from the second end F of the body 10 before assembling the top button 50, or the top button 50 can be assembled first and the housing 40 slides in from the first end E.

[0087] According to the styling accessory of this application embodiment, the outer shell 40 is sleeved on the outside of the main body 10. The second air outlet 41 is connected to the first air outlet 11. By setting the aperture size, aperture distribution and air outlet angle of the second air outlet 41, the airflow can be guided in a secondary manner to meet different hair care scenarios. Users do not need to replace the whole body. They can achieve a variety of hair care operations simply by replacing different outer shells 40. The outer shell 40 abuts against the side of the base 20 near the main body 10, thereby preventing the outer shell 40 from separating from the main body 10 by axially limiting the outer shell 40. At the same time, the base 20 and the outer shell 40 are tightly abutted, which can also prevent foreign objects and dust from entering through the gap between the outer shell 40 and the base 20.

[0088] like Figures 1-3 As shown, in some embodiments, the first end E of the body 10 is further provided with a first limiting member 14, and the outer shell 40 is provided with a second limiting member 42. The first limiting member 14 and the second limiting member 42 cooperate to restrict the outer shell 40 from rotating relative to the body 10.

[0089] The first limiting member 14 is disposed on the outer wall of the first end E of the body 10, and is in the form of a protrusion or a groove. It can be disposed singly or multiple members can be evenly distributed along the outer periphery of the body 10. The first limiting member 14 extends along the axial direction of the body 10. The height of the protrusion or the depth of the recess of the first limiting member 14 is adapted to the second limiting member 42 on the outer shell 40 to ensure that they can form an effective barrier when they come into contact, while not protruding excessively from the outer surface of the outer shell 40.

[0090] The second limiting member 42 is formed as a groove or magnetic member corresponding to the first limiting member 14, and its position corresponds to the first limiting member 14. For example, one of the second limiting member 42 and the first limiting member 14 is a permanent magnet, and the other is made of magnetic material; or, both the second limiting member 42 and the first limiting member 14 are permanent magnets, but their polarities are opposite.

[0091] After the first limiting member 14 and the second limiting member 42 are engaged or attracted, they can form a circumferential constraint, restricting the relative rotation of the outer shell 40 and the body 10 in the circumferential direction. At the same time, they can play an auxiliary role in axial positioning. In the process of gradually engaging the first limiting member 14 and the second limiting member 42, the relative position of the outer shell 40 and the body 10 is also gradually adjusted.

[0092] For example, the first limiting member 14 is a strip-shaped protrusion, and two strip-shaped protrusions are spaced apart on the outer wall of the body 10. The strip-shaped protrusions extend axially along the cylindrical outer wall. The second limiting member 42 is a strip-shaped slot. The end of the strip-shaped slot near the base 20 is open. When the outer shell 40 is inserted from the second end F of the body 10, the strip-shaped slot gradually approaches the strip-shaped protrusion and gradually makes the strip-shaped protrusion fully inserted. This can limit the relative position of the outer shell 40 and the body 10 in the circumferential direction, thereby ensuring that the second air outlet 41 on the outer shell 40 can completely correspond to the first air outlet 11 on the body 10.

[0093] For example, the first limiting member 14 is an annular boss and the second limiting member 42 is an annular groove, wherein both the annular boss and the annular groove are partially annular structures and their corresponding circumferential angles are less than 360°.

[0094] According to the styling accessory of the present application embodiment, the first limiting member 14 and the second limiting member 42 cooperate to form a circumferential limiting structure, which prevents the outer shell 40 from rotating relative to the body 10, avoids repeated angle adjustments during installation, improves assembly convenience, and prevents the outer shell 40 from changing the preset air supply mode due to accidental force rotation during use. In addition, the second limiting member 42 provided on the outer shell 40 can also play a foolproof role, so that it is put into the body 10 in the correct direction during assembly.

[0095] like Figure 1 and Figure 2 As shown, in the styling accessory according to the embodiment of this application, a wedge-shaped portion 15 is also provided on the outer wall of the main body 10 or the inner wall of the outer shell 40. The wedge-shaped portion 15 is located on the side of the first limiting member 14 near the second end F and adjacent to the first limiting member 14. The thickness of the wedge-shaped portion 15 gradually increases radially in the direction from the second end F to the first end E.

[0096] The wedge-shaped portion 15 can be disposed on the outer wall of the body 10 or on the inner wall of the outer shell 40. The wedge-shaped portion 15 is located on the side of the first limiting member 14 near the second end F and adjacent to the first limiting member 14. As the outer shell 40 moves from the second end F to the first end E and gradually fits into the body 10, the increased thickness of the wedge-shaped portion 15 will generate radial compression between the outer shell 40 and the body 10, forming a preload force. Radial refers to the axis perpendicular to the body 10 or the axis of the outer shell 40.

[0097] The wedge-shaped portion 15 has a first guide slope 151, meaning that when the wedge-shaped portion 15 is disposed on the body 10, the distance between the first guide slope 151 and the cavity gradually increases in the direction from the second end F to the first end E. When the wedge-shaped portion 15 is disposed on the outer shell 40, the distance between the first guide slope 151 and the cavity gradually decreases in the direction from the second end F to the first end E.

[0098] According to the styling accessory of this application embodiment, when the outer shell 40 and the body 10 are assembled, the increased thickness of the wedge-shaped portion 15 will generate radial compression between the outer shell 40 and the body 10, forming a pre-tightening force. This further adjusts the fitting gap between the outer shell 40 and the body 10, preventing the outer shell 40 from wobbling relative to the body 10. Simultaneously, due to the presence of the wedge-shaped portion 15, even if there are manufacturing tolerances in the first limiting member 14 and the second limiting member 42, the outer shell 40 and the body 10 can be prevented from loosening. Furthermore, since the thickness of the wedge-shaped portion 15 gradually increases radially in the body 10, the outer shell 40 will feel increasing tactile feedback as it gradually fits into the body 10. Users can sense whether the installation is in place by touch, further improving operational efficiency.

[0099] like Figure 1 , Figure 7 , Figure 8 as well as Figure 11 As shown, in some embodiments, the second end F of the body 10 is fitted with a top button 50, which is snapped into the body 10. The end face of the top button 50 facing the body 10 extends beyond the body 10 to abut against the end face of the outer casing 40.

[0100] The top button 50 is disc-shaped, cap-shaped, or cone-shaped for easy gripping. The top button 50 covers the opening at the second end F of the main body 10. The inner side of the top button 50, facing the main body 10, has an annular snap-fit ​​flange or latching structure. The width of the top button 50 extending beyond the end face of the main body 10 is appropriate, forming a flat or curved stop area to ensure complete contact with the end face of the outer casing 40. The top button 50 stops against the outer casing 40, limiting its movement and preventing it from moving axially along the main body 10.

[0101] For example, the inner side of the top button 50 is provided with multiple elastic barbed buckles, and the second end F of the body 10 is provided with multiple mating slots. Pressing the top button 50 causes the barbed buckles to elastically deform and engage with the mating slots. In this way, the reliability of the assembly between the top button 50 and the body 10 can be further improved.

[0102] In the above embodiments, the buckles can also be asymmetrically arranged, thereby preventing mistake-proofing when operators are assembling the equipment.

[0103] For example, a rigid flange may also be provided on the inner side of the top button 50, and an annular mating groove is provided on the second end F of the body 10. The rigid flange is inserted into the mating groove and interference fits.

[0104] In the above embodiments, a sealing edge can also be provided around the top button 50, which is sleeved on the outside of the housing 40, thereby further sealing the housing 40 and the top button 50.

[0105] According to the styling accessory of this application embodiment, the top button 50 can both serve to radially limit the outer shell 40 and, through its shape design, facilitate user gripping and styling. The top button 50 is snapped into the inner wall of the second end F of the body 10 via a snap fastener, thereby achieving a fixed connection. Manufacturing the top button 50 and the body 10 separately simplifies the manufacturing process, while snapping them together simplifies the assembly process. During assembly, the outer shell 40 can be inserted into the body 10 from the second end F. After the outer shell 40 is assembled in place, the top button 50 is snapped into the body 10. The end face of the top button 50 facing the body 10 extends beyond its end and directly abuts against the end face of the outer shell 40, thereby restricting the position of the outer shell 40 at the other end in the axial direction. During use, the top button 50 prevents the outer shell 40 from sliding along the axis of the body 10 towards the second end F through its abutting force. Combined with the base 20 abutting the other end of the outer shell 40, this further enhances the stability of the outer shell 40 assembly, ensuring that it will not loosen in a high-frequency vibration working environment.

[0106] In some embodiments, the radial cross-section of the top button 50 gradually shrinks from the fixed end to the free end along the axial direction of the cylindrical body. This variation conforms to the natural curvature of the human hand, so that the contact pressure between the palm, fingers and the handle surface is evenly distributed, making it less tiring to hold for a long time. At the same time, the gradually shrinking structure reduces the amount of material used in the top button 50, achieving lightweight design of the accessory while maintaining grip strength.

[0107] In some embodiments, the outer wall of the top button 50 is provided with a plurality of anti-slip protrusions spaced circumferentially along the top button 50. The anti-slip protrusions extend from the free end of the top button 50 to the circumferential contour of the second end F of the body 10. The anti-slip protrusions increase the roughness of the contact surface, providing uniform friction regardless of whether the fingers hold the narrow part of the free end or the wider part near the body 10, thus preventing slippage. The anti-slip protrusions extend from the free end of the top button 50 to the circumferential contour of the second end F of the body 10. When the user rotates the body 10 or adjusts the angle, the thumb and forefinger can accurately control the rotation range by sensing the position of the anti-slip protrusions.

[0108] like Figure 8 and Figure 9 As shown, in some embodiments, a partition 60 fixed to the cylindrical wall of the body 10 is also installed inside the cavity of the body 10, and the partition 60 and the top button 50 are connected by a first fastener 62.

[0109] The partition 60 is a thin sheet in the shape of a circle, ellipse, or polygon, with a size slightly smaller than the inner diameter of the body 10. The edge of the partition 60 may be provided with a first flange to ensure a tight fit with the cylindrical wall of the body 10. Multiple reinforcing ribs may also be provided on the partition 60 to increase its strength. The partition 60 extends radially along the body 10, separating the cavity from the top button 50. The surface of the partition 60 may be flat, or have an arc shape or a specific curved surface. Exemplarily, the partition 60 is fixed to the cavity of the body 10 by multiple second fasteners, such as two or three second fasteners, wherein the second fasteners may be screws, bolts, or pins.

[0110] The number of partitions 60 is one or more. When multiple partitions 60 are provided, the multiple partitions 60 are arranged sequentially at intervals along the axial direction of the body 10.

[0111] In some embodiments, the partition 60 can also be configured as a thin-walled structure with a hollow cavity, which can further improve the heat insulation effect.

[0112] The top button 50 can have a threaded hole or a connecting post on the side facing the cavity for connection with the first fastener 62. When the top button 50 has a threaded hole, it is a blind hole and opens towards the cavity. When the top button 50 has a connecting post, the surface of the connecting post has external threads or a positioning groove. The threaded hole or connecting post extends along the axial direction of the body 10, which ensures that the connection path of the first fastener 62 on the partition 60 is minimized and the force is evenly distributed.

[0113] The first fastener 62 can be a screw, bolt, or pin. The length of the first fastener 62 is adapted to the distance between the top button 50 and the partition 60. The first fastener 62 passes through the mounting hole on the partition 60 and engages with the threaded hole of the top button 50, or is sleeved on the outside of the connecting post for fixation.

[0114] During assembly, the first fastener 62 is fixed to the partition plate 60. The partition plate 60 is first fixed inside the body 10, and then the top button 50 is aligned with the partition plate 60. Rotating the top button 50 gradually tightens the threaded hole or connecting post with the first fastener 62. A second flange 52 extending towards the body 10 is also provided in the circumference of the top button 50, which ensures that the top button 50 fits tightly against the cylinder wall of the body 10.

[0115] like Figure 10 and Figure 11As shown, alternatively, the top button 50 is provided with a second flange 52 and a flexible hook 53, and the body 10 is provided with a second locking groove 17. After the partition 60 is assembled, the top button 50 is first locked to the body 10, the flexible hook 53 is locked into the second locking groove 17, and the second flange 52 abuts against the inner wall of the body 10. Then, a tool is inserted from the first end E of the body 10 to tighten the first fastener 62 and the top button 50. The second flange 52 plays a guiding role in the locking process of the top button 50 and the body 10, ensuring that the flexible hook 53 can be aligned with the second locking groove 17.

[0116] For example, on the side of the second snap-fit ​​groove 17 opposite to the first end E, a second guide slope 16 is provided on the inner wall of the body 10, so as to guide the elastic snap hook 53 to snap smoothly into the second snap-fit ​​groove 17.

[0117] According to the styling accessory of this application embodiment, when a user needs to hold the top button 50 for hair styling, if the airflow in the cavity is hot air, the user may experience discomfort due to the heat transmitted when holding the top button 50. By setting the partition 60, the hot air can be effectively blocked from being transmitted to the top button 50 through the cylinder wall, preventing heat from accumulating near the top button 50. The top button 50 is connected to the partition 60 by the first fastener 62, which can further tighten the fit between the top button 50 and the body 10, preventing the top button 50 from shifting from the cavity due to loosening, which would affect the heat insulation effect or cause air leakage, thus ensuring the airtightness and stability of the air supply.

[0118] In some embodiments, the top button 50 is provided with a threaded hole formed as a blind hole, the threaded hole opening towards the cavity, the partition 60 is provided with a mounting hole in the center, the first fastener 62 passes through the mounting hole and the threaded hole, and the end of the first fastener 62 abuts against the side of the partition 60 away from the top button 50.

[0119] In the above embodiments, the mounting hole is either a smooth hole or has a thread.

[0120] According to the styling accessory of this application embodiment, the threaded hole of the top button 50 is set as a blind hole and faces the inside of the cavity, so that the appearance of the top button 50 is relatively intact, preventing external impurities such as dust, liquid or hair from entering the cavity through the hole, and also making the appearance relatively smooth, avoiding scratching the user's hands. It is assembled with the first fastener 62 through the threaded hole. The end of the first fastener 62 abuts against the partition 60 to form an axial limit. The helical structure of the thread generates an axial preload, preventing loosening due to vibration or gripping force, and further improving the stability and reliability of the installation of the top button 50.

[0121] like Figure 8As shown, in some embodiments, a guide cylinder 51 is provided on the side of the top button 50 facing the partition 60, a third limiting member 63 is provided on the partition 60, the third limiting member 63 is sleeved on the outside of the guide cylinder 51, and a threaded hole is provided inside the guide cylinder 51.

[0122] The guide cylinder 51 is cylindrical or square-shaped, with an outer diameter smaller than the inner diameter of the top button 50. The guide cylinder 51 extends axially along the body 10 and is perpendicular to the inner end face of the top button 50. The central axis of the guide cylinder 51 coincides with or is eccentrically positioned to the central axis of the top button 50. The guide cylinder 51 can be integrally molded from the same material as the top button 50, such as ABS or PC. The wall thickness of the guide cylinder 51 is uniform throughout to ensure that it will not deform under stress when assembled with the first fastener 62.

[0123] The third limiting member 63 is a hollow cylindrical or square structure with an inner diameter slightly larger than the outer diameter of the guide cylinder 51 and a height slightly smaller than the height of the guide cylinder 51. The third limiting member 63 is arranged circumferentially along the assembly hole and extends axially along the body 10, which facilitates the passage of the first fastener 62. The third limiting member 63 is perpendicular to the surface of the partition 60 and can be integrally formed with the partition 60.

[0124] The third limiting member 63 can cooperate with the guide cylinder 51 to achieve the pre-positioning of the top button 50 and the partition plate 60, which facilitates the alignment of the assembly hole and the threaded hole, ensures the coaxiality of the assembly hole and the threaded hole, and reduces the difficulty of assembling the first fastener 62 with the top button 50.

[0125] According to the styling accessories of this application embodiment, the guide cylinder 51 of the top button 50 and the third limiting member 63 of the partition 60 can cooperate to achieve pre-positioning. During installation, the third limiting member 63 slides along the inner or outer wall of the guide cylinder 51, and the two are sleeved to form a radial limiting, which restricts the top button 50 from shaking or rotating in the radial direction, guides the threaded hole to align with the assembly hole, so that the threaded hole and the first fastener 62 can maintain coaxiality before connection, or guides the first fastener 62 to align with the threaded hole, so that the threaded hole can maintain coaxiality during the connection with the first fastener 62, avoids offset or jamming during blind installation, and improves assembly efficiency.

[0126] The hair care machine according to an embodiment of this application includes a handle and the styling accessories described above.

[0127] Specifically, the handle has a proximal end and a distal end, with an air inlet at the proximal end, and the handle includes a fan assembly and a motor assembly; the base 20 of the styling accessory engages with the distal end of the handle.

[0128] According to the hair care machine of this application embodiment, the handle and the base 20 are quickly assembled and disassembled by a snap-fit ​​connection. When the motor assembly drives the fan assembly 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 cavity of the body 10 through the air inlet of the base 20, and flows out through the first air outlet 11. During this process, due to the stable connection between the base 20 and the body 10, airflow leakage or structural noise caused by the vibration of the fan assembly or motor assembly can be avoided. At the same time, by setting the base 20 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.
