Description

Technical Field

[0001] This invention relates to the field of hair dryer technology, and in particular to a hair care nozzle and a hair dryer having the hair care nozzle. Background Technology

[0002] In the field of personal care appliances, hair dryers, as core tools for daily styling and hair care, have always had their functional iterations revolve around users' dual needs for convenient styling and effective hair care. To enhance hair care capabilities, some existing hair dryers integrate a care medium release device within the hair care nozzle. By releasing care ingredients such as collagen, essential oils, and negative ion generators in the airflow path, they achieve the effect of nourishing hair strands while drying it.

[0003] However, these hair conditioning nozzles with integrated conditioning media often suffer from structural design flaws: the conditioning media typically employs complex installation methods such as snap-fit, threaded engagement, or locking clips. Users must align the media at a specific angle and apply precise pressure when changing or replenishing it, making the process cumbersome, especially for elderly users or those with weaker hand strength. Furthermore, the complex installation structure can easily lead to improper installation of the conditioning media, causing airflow leakage and uneven release of conditioning ingredients, affecting both the hair conditioning effect and the product's reliability. Therefore, there is an urgent need for a hair conditioning nozzle with easily installable and replaceable conditioning media.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0056] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0057] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0058] The hair care nozzle disclosed in this invention uses a plug-in method to install the adsorption carrier 20 (such as an adsorption cotton swab), which simplifies the installation process of the adsorption carrier 20. Users can complete the installation operation simply by manually plugging and unplugging, greatly reducing the barrier to entry for users. At the same time, the plug-in method for installing the adsorption carrier 20 also greatly facilitates the replacement of the adsorption carrier 20 in the future. That is, when the adsorption carrier 20 needs to be replaced after one or several uses, the user only needs to gently pull out the old adsorption carrier 20 and then insert the new adsorption carrier 20 to complete the replacement. The whole process is quick and efficient, requiring no professional assistance, and significantly improving the ease of use and maintenance efficiency of the product.

[0059] The following five embodiments will be used to describe in detail the hair care nozzle disclosed in this invention.

[0060] Example 1

[0061] Combination Figures 1-4 As shown, the hair care nozzle includes a fan cover 10 and an adsorption carrier 20. The fan cover 10 includes a first end face S1 and a second end face S2 arranged opposite to each other. The first end face S1 serves as the air outlet of the hair care nozzle, and has an insertion interface 11 for the adsorption carrier 20 to pass through and a flow outlet 12 for airflow. The second end face S2 is the connecting end, and has an air inlet 13 for airflow and a connecting structure 14 (such as a magnetic or snap-fit ​​structure) for quick connection with the air outlet of the hair dryer. The fan cover 10 has an internal airflow channel 15 connecting the air inlet 13 and the air outlet 12, which guides the high-speed airflow flowing in from the air inlet 13 smoothly along a preset path to the air outlet 12, reducing airflow loss and achieving directional and concentrated airflow.

[0062] In this embodiment, combined with Figure 2 , Figure 3 and Figure 5 As shown, the fan cover 10 includes a housing 101 and an end cap 102. The housing 101 is a hollow structure, with an insertion port 11 and an air outlet 12 at one end, and the other end connected to the end cap 102. The end cap 102 has an air inlet 13 and a connecting structure 14. The housing 101 has an internal airflow channel 15 connecting the air outlet 12 and the air inlet 13, guiding the high-speed airflow flowing in from the air inlet 13 smoothly along a preset path to the air outlet 12. In practical implementation, the airflow generated by the blower enters the airflow channel 15 through the air inlet 13 and is blown outwards through the air outlet 12.

[0063] Furthermore, combined Figure 1 and Figure 2 As shown, to increase the airflow jet velocity, the cross-sectional area of ​​the housing 101 gradually decreases from the air inlet 13 to the air outlet 12. By compressing the airflow cross-sectional area, the airflow can be pressurized and accelerated, ultimately increasing the airflow velocity at the air outlet 12.

[0064] Furthermore, such as Figure 2 As shown, the housing 101 is provided with multiple air outlets 12, which are arranged around the insertion interface 11 in a cross shape. Compared with a single circular or flat air outlet 12, the cross-shaped four-way air outlet method can make the airflow act on different areas of the hair at the same time.

[0065] Furthermore, such as Figure 3 As shown, the connection structure 14 on the end cap 102 is preferably a magnetic connection, wherein the end cap 102 has a receiving groove 102a, and a magnet 102b is embedded in the receiving groove 102a. In implementation, the optimal implementation is to use an annular groove for the receiving groove 102a and an annular magnet for the magnet 102b. The magnetic connection can achieve quick assembly and disassembly in one second, and has higher fitting accuracy, which can effectively prevent loosening and falling off during use. In other embodiments, mechanical connection structures such as snap-fit ​​or screw-on can also be used as needed to meet the usage requirements of different scenarios.

[0066] Furthermore, the air inlet 13 on the end cap 102 is preferably an annular air inlet. Meanwhile, combined with... Figures 3-5 As shown, to optimize airflow introduction efficiency and stability, the end cover 102 is provided with an arc-shaped guide plate 16 at the corresponding position of the air inlet 13. The arc-shaped guide plate 16 preferably adopts a circular layout around the air inlet 13. On the one hand, the arc-shaped guide plate 16 guides the originally divergent airflow smoothly into the internal channel along a preset path through the curved surface, avoiding turbulence loss caused by the airflow impacting the inner wall of the housing 101; on the other hand, through the converging effect of the arc structure, it integrates the dispersed airflow into a concentrated columnar airflow, which is conducive to the high-speed airflow output of the air outlet 12.

[0067] Combination Figures 1-5 As shown, the adsorption carrier 20 includes an end cap 21 and an adsorption medium 22, one end of which is connected to the end cap 21 via a plug-in connection. The adsorption medium 22 is preferably a rod-shaped structure with capillary adsorption properties, such as a cotton swab, used to hold liquid conditioning media such as hair oil, conditioner, and moisturizing essence. The adsorption carrier 20 is detachably plugged into the inside of the blower shroud 10 via the plug-in interface 11 and is at least partially exposed in the airflow channel 15. When the airflow passes through at high speed, the conditioning medium evaporates evenly under the action of the airflow and is blown out with the airflow, achieving simultaneous blow-drying styling and hair conditioning, improving ease of use and conditioning effect.

[0068] Furthermore, such as Figure 5As shown, in this embodiment, the end cap 21 can prevent the user from touching the adsorption medium 22 when assembling the adsorption carrier 20, thus avoiding contamination of the care medium and improving the user experience. In this embodiment, the end cap 21 is provided with a decorative hole 211, which can improve the aesthetics of the hair care nozzle. When the adsorption medium 22 is not inserted into the fan cover 10, it is stored in a protective sleeve (not shown). After the end cap 21 is closed on the protective sleeve, a sealed space for the adsorption medium 22 is formed.

[0069] Combination Figures 1-5 As shown, to improve the ease of disassembly of the adsorption carrier 20, a press-and-lift mechanism 30 is provided inside the fan cover 10. The press-and-lift mechanism 30 includes a movable part 31, an elastic part 32, and a switch part 33. These components work together to achieve a cyclical action of pressing to lock and pressing again to unlock.

[0070] like Figure 6 As shown, the movable component 31 can reciprocate linearly relative to the fan cover 10 along the insertion direction of the adsorption carrier 20. One end of it is provided with a mounting part 311 for mounting the adsorption carrier 20. Through this mounting part 311, it can be connected to the adsorption carrier 20 to achieve a stable fixation of the adsorption carrier 20 and prevent loosening when the high-speed airflow blows. The opposite end is provided with a locking tongue 312 with a bevel, which can smoothly engage and disengage with the elastic claw structure in the switch component 33. Here, the mounting part 311 is formed by multiple limiting posts L arranged along the circumferential direction of the movable component 31.

[0071] The switch element 33 adopts a push-button self-locking switch structure, which includes two opposing elastic claws 331 and a locking mechanism (such as a spring hook, heart-shaped groove, etc.). Both elastic claws 331 are connected to the locking mechanism. Figure 3 As shown, when the locking mechanism of the switch 33 is in the pressed-lock state, the two elastic claws 331 approach each other and remain close under the action of the locking mechanism to clamp the locking tongue 312, thereby enabling the movable member 31 and the switch 33 to be in a connected state. Figure 4 As shown, when the locking mechanism of the switch 33 is in the press-unlock state, the two elastic claws 331 can separate from each other and maintain a certain distance, no longer clamping the locking tongue 312, thereby enabling the movable part 31 to be separated from the switch 33.

[0072] One end of the elastic element 32 abuts against the movable element 31, and the opposite end abuts against the inner wall of the fan cover 10 to drive the movable element 31 to reset. When the movable element 31 and the switch element 33 are locked, the elastic element 32 is in a compressed and energy-storing state; when the movable element 31 and the switch element 33 are unlocked, the spring quickly releases its elastic potential energy, driving the movable element 31 to quickly reset along the axial direction to the outside of the fan cover 10, causing the adsorption carrier 20 to automatically pop out a certain length, forming an operating part that is easy to hold, so that the user can easily pull out the carrier to complete the replacement.

[0073] In specific implementation, combined with Figure 3 and Figure 4 As shown, when installing the adsorption carrier 20, the user inserts the adsorption carrier 20 into the insertion interface 11 of the fan cover 10, and the end of the adsorption carrier 20 precisely aligns with the movable part 31 of the pressing and lifting mechanism 30. Then, the user gently presses the end face of the adsorption carrier 20, and the force is transmitted through the carrier to the movable part 31, driving it to move inward and compress the internal elastic part 32. When the movable part 31 moves to the preset position, the locking tongue 312 triggers the locking mechanism of the switch part 33, causing the elastic claws on both sides to close synchronously and clamp the locking tongue 312, thereby locking the movable part 31 and the switch part 33. At this time, the adsorption carrier 20 is completely embedded inside the fan cover 10 and remains flush with the end face of the fan cover 10, ensuring that the adsorption carrier 20 is completely hidden, achieving a balance between aesthetics and stability.

[0074] When the adsorption carrier 20 needs to be replaced, the user simply presses the end face of the adsorption carrier 20 again. The force is transmitted to the movable part 31, which triggers the locking mechanism of the switch 33 through the locking tongue 312, putting it in the unlocked state. The two elastic claws 331 on the switch 33 move away from each other and release the locking tongue 312, thus unlocking the movable part 31 from the switch 33. At this time, the compressed elastic element 32 releases its pre-stored elastic force, driving the movable part 31 to automatically extend the carrier outward to a certain length from the fan cover 10, so that the end of the carrier protrudes from the end face of the fan cover 10, forming an operating part that is easy to grip. The user can easily pull out the adsorption carrier 20 by simply pinching the exposed part without any tools. The entire replacement process is quick and smooth, greatly improving maintenance convenience.

[0075] Combination Figures 3-5 as well as Figure 7 As shown, the fan cover 10 also has a bracket 40 located within the airflow channel 15. The bracket 40 can be used to assemble the aforementioned pressing and lifting mechanism 30. Specifically, the bracket 40 includes a base 41 and multiple connecting parts 42, such as... Figure 7 As shown, there are four connectors 42. The connectors 42 are distributed around the base 41 and fixedly connected to the base 41. The connectors 42 enclose a receiving space M that can accommodate the pressing and lifting mechanism 30. Furthermore, a gap is formed between two adjacent connectors 42, which facilitates the passage of airflow and reduces the influence of the bracket 40 on the airflow.

[0076] Furthermore, to facilitate the assembly of the pressing and lifting mechanism 30, the base 41 within the receiving space M is provided with an assembly hole 411 for mounting the switch 33. A ring-shaped limiting groove 412 is also provided around the assembly hole 411 to fix the elastic member 32. This limiting groove 412 effectively prevents displacement during compression or reset. The movable member 31 is located within the receiving space M and can slide relative to the connecting member 42 along the insertion direction of the adsorption carrier 20, as shown in the figure. The movable member 31 is provided with a guide groove 313, and the connecting member 42 is provided with a guide rail 421 that cooperates with the guide groove 313. Through the cooperation of the guide groove 313 and the guide rail 421, the movable member 31 can slide stably along the insertion direction of the adsorption carrier 20.

[0077] Furthermore, to ensure the bracket 40 is stably installed inside the wind cover 10, combined with Figure 5 , Figure 7 and Figure 8 As shown, on one hand, the end cap 102 is provided with a mounting groove 102c, and the base 41 is provided with a boss 413 that matches the mounting groove 102c. Through the cooperation of the mounting groove 102c and the boss 413, a stable connection is achieved between the base 41 and the end cap 102. On the other hand, one end of the connector 42 is fixedly connected to the base 41, and the opposite end is detachably connected to the housing 101 of the shroud 10, combining... Figure 5 and Figure 7 As shown, the connector 42 is provided with a snap hook P, and the housing 101 is provided with a socket Q that mates with the snap hook P. Through the engagement of the snap hook P and the socket Q, the bracket 40 can be quickly installed and fixed without additional tools, while ensuring that the structure is not easily loosened or detached during long-term use. Through this dual connection structure, the bracket 10 can be stably fixed inside the fan cover 10, providing a reliable installation base for the pressing and lifting mechanism 30.

[0078] Furthermore, in this embodiment, as Figure 5 As shown, the housing 101 includes an inner housing 101a and an outer housing 101b located outside the inner housing 101a. The inner housing 101a is provided with the insertion port Q, and the connector 42 engages with the insertion port Q on the inner housing 101a via a fastening hook P thereon to fix it to the inner housing 101a.

[0079] Furthermore, in this embodiment, as Figure 7As shown, the bracket 40 also includes an air guide plate 43. One end of the connector 42 is fixedly connected to the base 41, while the other end supports the air guide plate 43, forming a frame that balances stability and breathability. The air guide plate 43 adopts a conical design, with its cross-sectional area gradually decreasing towards the direction away from the base 41. A hollow section 431 is provided in the middle for the movable part 31 to pass through. Multiple ventilation holes 432 are evenly distributed around the hollow section 431, which not only ensures smooth airflow and reduces wind resistance, but also guides the airflow towards the center through the conical curved surface, greatly improving local wind pressure and wind speed, allowing the wind force to act more concentratedly on the target area, and effectively avoiding efficiency loss and reduced shape accuracy caused by airflow diffusion.

[0080] Example 2

[0081] Combination Figures 9-11 As shown, the hair care nozzle includes a fan cover 10 and an adsorption carrier 20. The fan cover 10 includes a first end face S1 and a second end face S2 arranged opposite to each other. The first end face S1 serves as the air outlet of the hair care nozzle, and it has an insertion interface 11 for the adsorption carrier 20 to pass through and a flow outlet 12 for airflow. The second end face S2 is the connecting end, and it has an air inlet 13 for airflow and a connecting structure 14 (such as a magnetic or snap-fit ​​structure) adapted to the air outlet 12 of the hair dryer, facilitating quick connection with the hair dryer (not shown). The fan cover 10 has an internal airflow channel 15 connecting the air inlet 13 and the air outlet 12, which guides the high-speed airflow flowing in from the air inlet 13 smoothly along a preset path to the air outlet 12, reducing airflow loss and achieving directional and concentrated airflow.

[0082] Unlike Embodiment 1, in this embodiment, the support 40 is not required inside the air cover 10 of the hair care nozzle, which effectively reduces production costs while fulfilling basic functions. When the support 40 is not provided, as... Figure 11 As shown, the wind cover 10 has multiple baffles D distributed circumferentially inside, and the multiple baffles D enclose a space to accommodate the pressing and lifting mechanism 30.

[0083] At the same time, unlike Embodiment 1, in this embodiment, the housing 101 may not have an inner housing, which can also effectively reduce production costs while meeting basic functions.

[0084] Example 3

[0085] Combination Figures 12-14The hair care nozzle includes a fan cover 10 and an adsorption carrier 20. The fan cover 10 includes a first end face S1 and a second end face S2 arranged opposite to each other. The first end face S1 serves as the air outlet of the hair care nozzle, with an air outlet 12 for airflow. The second end face S2 is the connecting end, with an air inlet 13 for airflow, an insertion interface 11 for the adsorption carrier 20 to pass through and be fixed, and a connecting structure 14 (such as a magnetic or snap-fit ​​structure) adapted to the air outlet 12 of the hair dryer for quick connection. The fan cover 10 has an internal airflow channel 15 connecting the air inlet 13 and the air outlet 12, used to guide the high-speed airflow flowing in from the air inlet 13 smoothly along a preset path to the air outlet 12, reducing airflow loss and achieving directional and concentrated air delivery.

[0086] In this embodiment, the fan cover 10 includes a housing 101 and an end cap 102. The housing 101 is a hollow structure, with an air outlet 12 at one end and the other end connected to the end cap 102. The end cap 102 has an insertion interface 11, an air inlet 13, and a connecting structure 14. The internal structure of the housing 101 has an airflow channel 15 connecting the air outlet 12 and the air inlet 13 to guide the high-speed airflow flowing in from the air inlet 13 to be smoothly transported to the air outlet 12 along a preset path.

[0087] Furthermore, such as Figure 12 As shown, in this embodiment, in order to improve the airflow injection speed, the structure of the housing 101 is the same as that in Embodiment 1, and will not be described in detail here.

[0088] Furthermore, such as Figure 12 As shown, the housing 101 is provided with multiple air outlets 12, and the arrangement of the multiple air outlets 12 is the same as in Embodiment 1, which will not be described in detail here.

[0089] Furthermore, such as Figure 14 As shown, the connection structure 14 on the end cap 102 is preferably a magnetic type, wherein, as Figure 13 As shown, in this embodiment, the magnetic attraction scheme is the same as that in Embodiment 1, and will not be described in detail here.

[0090] Furthermore, the air inlet 13 on the end cap 102 is preferably an annular air inlet. Meanwhile, as... Figure 14 As shown, in order to optimize the efficiency and stability of airflow introduction, the end cover 102 is provided with an arc-shaped guide plate 16 at the corresponding position of the air inlet 13. For details, please refer to Embodiment 1, which will not be described in detail here.

[0091] like Figure 13As shown, the adsorption carrier 20 includes an end cap 21 and an adsorption medium 22. One end of the adsorption medium 22 is connected to the end cap 21 via a plug-in connection. For example, the end cap 21 has a plug-in groove that matches the adsorption medium 22. One end of the adsorption medium 22 is inserted into the plug-in groove, and a firm connection is formed through interference fit, etc., to ensure that the two will not easily separate during use. The end cap 21 can prevent the user from touching the adsorption medium 22 when assembling and pressing, avoiding contamination of the care medium and improving the user experience.

[0092] Furthermore, the end cap 21 and the insertion interface 11 of the shroud 10 adopt a detachable threaded connection scheme, such as... Figure 13 As shown, the outer wall of the end cap 21 is provided with a first thread, and the inner wall of the insertion interface 11 is provided with a matching second thread. Assembly and disassembly can be completed by rotating the end cap 21. The threaded connection not only provides a stable locking force, preventing the adsorption carrier 20 from loosening and falling off during long-term use, but also facilitates users to regularly disassemble, clean, or replace the adsorption carrier, extending the product's service life. In this embodiment, the insertion interface 11 and the air inlet 13 are located on the same side, and the end cap 21 and the insertion interface 11 of the fan shroud 10 adopt a detachable threaded connection scheme. Of course, in other embodiments, the insertion interface 11 can also be located on the same side as the air outlet 12, and the end cap 21 and the insertion interface 11 of the fan shroud 10 also adopt a detachable threaded connection scheme.

[0093] In practice, when installing the adsorption carrier 20, first hold the end cap 21 and slowly insert the adsorption carrier 20 into the fan shroud 10 through the insertion interface 11. After the end cap 21 is aligned with the insertion interface 11, rotate the end cap 21 clockwise. With the help of the threaded connection, the end cap 21 can be firmly installed into the insertion interface 11, thus achieving a stable installation of the adsorption carrier 20. The entire process requires no additional tools and can be easily completed independently by the user. When it is necessary to replace the adsorption carrier 20, rotate the end cap 21 in the opposite direction until the end cap 21 separates from the fan shroud 10, and then pull out the adsorption carrier 20 for replacement.

[0094] In this embodiment, the end cap 21 is provided with an operating part 211 to facilitate the user to rotate the end cap 21.

[0095] Example 4

[0096] like Figures 15-17As shown, the hair care nozzle includes a fan cover 10 and an adsorption carrier 20. The fan cover 10 includes a first end face S1 and a second end face S2 arranged opposite to each other. The first end face S1 serves as the air outlet of the hair care nozzle, and has an insertion interface 11 for the adsorption carrier 20 to pass through and a flow outlet 12 for airflow. The second end face S2 is the connecting end, and has an air inlet 13 for airflow and a connecting structure 14 (such as a magnetic or snap-fit ​​structure) adapted to and easily connected to the air outlet 12 of the hair dryer. The fan cover 10 has an internal airflow channel 15 connecting the air inlet 13 and the air outlet 12, used to guide the high-speed airflow flowing in from the air inlet 13 smoothly along a preset path to the air outlet 12, reducing airflow loss and achieving directional and concentrated airflow.

[0097] In this embodiment, the fan cover 10 includes a housing 101 and an end cap 102. The housing 101 is a hollow structure, with an insertion interface 11 and an air outlet 12 at one end, and the other end connected to the end cap 102. The end cap 102 has an air inlet 13 and a connecting structure 14. The internal structure of the housing 101 has an airflow channel 15 connecting the air outlet 12 and the air inlet 13, so as to guide the high-speed airflow flowing in from the air inlet 13 to be smoothly transported to the air outlet 12 along a preset path.

[0098] Furthermore, such as Figure 15 As shown, in this embodiment, in order to improve the airflow injection speed, the structure of the housing 101 is the same as that in Embodiment 1, and will not be described in detail here.

[0099] Furthermore, such as Figure 16 As shown, the housing 10 is provided with multiple air outlets 12, and the arrangement of the multiple air outlets 12 is the same as in Embodiment 1, which will not be described in detail here.

[0100] Furthermore, the connection structure 14 on the end cap 102 is preferably a magnetic attraction scheme. For details of the magnetic attraction scheme, please refer to Embodiment 1, which will not be repeated here.

[0101] Furthermore, the air inlet 13 on the end cap 102 is preferably an annular air inlet. Meanwhile, as... Figure 17 As shown, in order to optimize the efficiency and stability of airflow introduction, the end cover 102 is provided with an arc-shaped guide plate 16 at the corresponding position of the air inlet 13. For details, please refer to Embodiment 1, which will not be described in detail here.

[0102] The adsorption carrier 20 includes an end cap 21 and an adsorption medium 22. One end of the adsorption medium 22 is connected to the end cap 21 via a plug-in connection. For example, the end cap 21 has a plug-in groove that matches the adsorption medium 22. One end of the adsorption medium 22 is inserted into the plug-in groove, and a firm connection is formed through interference fit or other means, ensuring that the two will not easily separate during use. The end cap 21 can prevent the user from touching the adsorption medium 22 during assembly and pressing, avoiding contamination of the care medium and improving the user experience.

[0103] Unlike Embodiment 3, in this embodiment, the end cap 21 on the adsorption carrier 20 and the insertion interface 11 of the fan shroud 10 adopt a detachable direct insertion connection scheme. That is, the end cap 21 and the insertion hole of the fan shroud 10 are interference-fitted to achieve direct insertion and fixation between the two without the need for additional connecting parts, which combines ease of assembly and reliable connection. In specific implementation, it is best if the insertion interface 11 on the fan shroud 10 and the air outlet 12 are on the same side. Of course, in other embodiments, the insertion interface 11 on the fan shroud 10 can also be on the same side as the air inlet 13, which can be set according to actual needs.

[0104] Example 5

[0105] Combination Figures 18-21 The hair dryer nozzle includes a fan cover 10 and an adsorption carrier 20. The fan cover 10 includes a housing 101 and an end cap 102. The housing 101 has a hollow structure, with an insertion interface 11 for the adsorption carrier 20 to pass through and a gas outlet 12 for airflow at one end, and the end cap 102 installed at the other end. The end cap 102 has an internal airflow channel 15 connecting the gas outlet 12 and the gas inlet 13. The end cap 102 is connected to the housing 101 and can rotate relative to it, and has the gas inlet 13 on it. In practice, the air generated by the hair dryer enters the airflow channel 15 through the gas inlet 13 and is blown out through the gas outlet 12.

[0106] Furthermore, such as Figure 18 As shown, the end of the housing 101 is provided with a plurality of air outlets 12 arranged around the insertion interface 11. The arrangement of the plurality of air outlets 12 is the same as that in Embodiment 1, and will not be described in detail here.

[0107] Furthermore, such as Figure 18 As shown, to increase the airflow injection speed, the structure of the housing 101 is the same as that in Embodiment 1, and will not be described in detail here.

[0108] Furthermore, such as Figure 20 As shown, the connection structure 14 on the end cap 102 is preferably a magnetic attraction scheme. For details of the magnetic attraction scheme, please refer to Embodiment 1, which will not be repeated here.

[0109] Furthermore, the air inlet 13 on the end cap 102 is preferably an annular air inlet 12. Meanwhile, as... Figure 20 As shown, in order to optimize the efficiency and stability of airflow introduction, the end cover 102 is provided with an arc-shaped guide plate 16 at the corresponding position of the air inlet 13. For details, please refer to Embodiment 1, which will not be described in detail here.

[0110] Furthermore, to achieve a rotatable connection between the end cap 102 and the housing 101, one of the end cap 102 and the housing 101 is provided with an annular groove, and the other is provided with a flange adapted to the annular groove. By embedding the flange into the annular groove, the two form a circumferential sliding fit structure, which can effectively limit the radial displacement of the flange and ensure that it always maintains a stable sliding trajectory in the groove.

[0111] like Figure 19 As shown, the adsorption carrier 20 includes an end cap 21 and an adsorption medium 22. One end of the adsorption medium 22 is connected to the end cap 21 via a plug-in connection. For example, the end cap 21 has a plug-in groove that matches the adsorption medium 22. One end of the adsorption medium 22 is inserted into the plug-in groove, and a firm connection is formed through interference fit, etc., to ensure that the two will not easily separate during use. The end cap 21 can prevent the user from touching the adsorption medium 22 when assembling and pressing, avoiding contamination of the care medium and improving the user experience.

[0112] Furthermore, the fan cover 10 is equipped with a rotary lifting mechanism 50, which can convert the rotational movement of the end cover 102 into the linear movement of the adsorption carrier 20. In specific implementation, after the adsorption carrier 20 is inserted into the fan cover 10 through the insertion interface 11, it can be connected to the rotary lifting mechanism 50. During the rotation of the end cover 102, the rotary lifting mechanism 50 can convert the rotational movement of the end cover 102 into the up and down movement of the adsorption carrier 20, thereby driving the adsorption carrier 20 to extend out of the fan cover 10, so that the user can take out the adsorption carrier 20 from the fan cover 10 for replacement.

[0113] Further, the rotary lifting mechanism 50 includes a sliding member 51 and a sleeve 52. The sliding member 51 is slidably disposed inside the fan shroud 10, capable of reciprocating linear motion within the fan shroud 10 along the insertion direction of the adsorption carrier 20. The sliding member 51 has a connecting portion 511 that connects to the adsorption carrier 20. The sleeve 52 is sleeved on the outside of the sliding member 51 and connected to the end cap 102. To convert the rotational motion of the end cap 102 into the up-and-down motion of the sliding member 51, one of the sleeve 52 and the movable member 31 is provided with a track groove, and the other is provided with a protrusion that can extend into the track groove. Under the action of the track groove and the protrusion, the rotational motion of the end cap 102 can be converted into the up-and-down motion of the sliding member 51. In this embodiment, combined with... Figure 22 and Figure 23As shown, it is optimal to have a track groove 521 on the sleeve 52 and a protrusion 512 on the sliding member 51.

[0114] When the adsorption carrier 20 is inserted into the fan cover 10 through the insertion interface 11, it can be connected with the connecting part of the sliding member 51. When it is necessary to remove the adsorption carrier 20, the user rotates the end cap 102. During the rotation, the end cap 102 can be converted into the upward movement of the movable member 31 by the cooperation of the track groove 521 and the protrusion 512 in the sliding member 51 and the sleeve 52. In this way, the sliding member 51 can drive the adsorption carrier 20 to extend out of the fan cover 10, so that the user can take out the adsorption carrier 20 from the fan cover 10 for replacement. After replacement, the adsorption carrier 20 is inserted into the hood 10 through the insertion interface 11 and connected to the sliding member 51. Then, the end cap 102 is rotated in the opposite direction. During the rotation of the end cap 102, with the cooperation of the track groove 521 and the protrusion 512 in the sliding member 51 and the sleeve 52, the rotational movement of the end cap 102 can be converted into the downward movement of the sliding member 51, so that the adsorption carrier 20 can be completely inserted into the hood 10, improving the aesthetics.

[0115] In this embodiment, as Figure 22 As shown, the sliding member 51 is provided with a plurality of circumferentially distributed baffles 511a, which together form the connecting part 511. In a specific implementation, the adsorption carrier 20 is connected to the connecting part 511 by an insertion method.

[0116] like Figure 20 As shown, to ensure stable axial movement of the sliding member 51, a guide sleeve 53 is provided inside the housing 101. The guide sleeve 53 is fitted over the outside of the sliding member 51, with one end of the guide sleeve 53 connecting to the insertion interface 11 and the other end extending into the sleeve 52. A guide groove extending along the length of the guide sleeve 53 is provided on the guide sleeve 53, allowing the protrusion 512 on the sliding member 51 to pass through the guide groove and enter the trajectory groove 521 of the sleeve 52. In practice, the user inserts the adsorption carrier 20 into the guide sleeve 53 through the insertion interface 11, further pushing the adsorption carrier 20 towards the sliding member 51. Once in place, it can be fixedly connected to the sliding member 51.

[0117] The present invention also discloses a hair dryer comprising the aforementioned hair care nozzle. This hair dryer makes the installation and replacement of hair care media more convenient, significantly improving the ease of use of the product.
