Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0054] In the realm of related technologies, while there is a wide variety of hair dryers on the market, many products remain relatively limited in functionality, particularly in hair care. Although some hair dryers have incorporated oil atomization structures in an attempt to enhance hair care by releasing essential oils, the actual results are often quite mediocre. The limited airflow area of ​​these hair dryers results in a very limited treatment area, making it difficult to achieve a comprehensive and even hair care effect.

[0055] Furthermore, different people have different hair types, hair volume, and hair care needs, and hair dryers on the market often lack personalized care functions to meet these different needs. This means that users often only get basic drying results when using hair dryers, and cannot enjoy a true hair care experience.

[0056] Embodiments of the present invention, with reference to Figures 1-16 As shown, a nozzle assembly for a hair dryer and a hair dryer are provided.

[0057] According to one embodiment of the present invention, please refer to... Figure 1 , Figure 2 and Figure 4 According to an embodiment of the present invention, a hair dryer nozzle assembly includes a mounting base 110; a rotating nozzle 200 rotatably connected to the mounting base 110, the rotating nozzle 200 being adapted to rotate relative to the mounting base 110 under the push of airflow; and a hair care component 900 disposed on the rotating nozzle 200, the hair care component 900 being used to store hair care products.

[0058] In this embodiment, the mounting base 110 is a supporting part of the nozzle assembly, used to fix and support the entire nozzle assembly structure. The rotating nozzle 200 forms the air outlet 201 of the hair dryer, and the airflow generated by the nozzle dries hair or other objects. The rotating nozzle 200 can be mounted on the base, forming an integral part with the base and simultaneously forming an air outlet duct. The shape and size of the rotating nozzle 200 affect the direction and distribution of the airflow. The hair care component 900 is specifically designed to store hair care products. Users can place frequently used hair care products, such as essential oils, in the storage component and access them at any time during the hair drying process for hair care.

[0059] The rotating nozzle 200 is rotatably connected to the mounting base 110. During use, the rotating nozzle 200 can rotate relative to the mounting base 110, effectively expanding the blowing area of ​​the hair dryer and covering a wider area. Due to the increased blowing area, the hair dryer can expand the treatment area during use, improve treatment efficiency, and dry hair faster, saving time and improving drying efficiency.

[0060] It is understood that the mounting base 110 is used to install and support the rotary nozzle 200. The rotary nozzle 200 can be installed into the mounting base 110 by means of bearing 500 or other rotatable connection, so that the rotary nozzle 200 can rotate relative to the mounting base 110.

[0061] It should be noted that the present invention does not impose specific limitations on the structure of the mounting base 110. The rotating nozzle 200 can be disposed above the mounting base 110 or inside the mounting base 110. By rotating the nozzle 200 and connecting it to the mounting base 110, multi-angle adjustment of the nozzle assembly is achieved, allowing the airflow direction of the hair dryer to be flexibly adjusted according to user needs, thus increasing ease of use.

[0062] It should be noted that the rotating nozzle 200 can rotate due to its own asymmetrical structure under the impetus of airflow, or it can rotate under the impetus of airflow through the grille component 230 in the following embodiment.

[0063] Understandably, in this embodiment, the hair dryer nozzle assembly includes a mounting base 110 and a rotating nozzle 200. The rotating nozzle 200 is rotatably connected to the mounting base 110 and is adapted to rotate relative to the mounting base 110 under the propulsion of airflow. A hair care component 900 is disposed on the rotating nozzle 200 and is used to store hair care products. In this embodiment, by providing a rotatable rotating nozzle 200 and installing the hair care component 900 on it, the rotating nozzle 200 can rotate relative to the mounting base 110 under the propulsion of airflow, thereby causing the hair care component 900 to rotate relative to the mounting base 110. The hair care product can then be evenly distributed on the hair as the nozzle rotates, achieving the effect of expanding the care area and providing even care. This design not only improves hair care efficiency but also makes the hair care process more even and meticulous.

[0064] According to one embodiment of the present invention, the hair care component 900 includes at least one of an essential oil module, an ionic hair care module, a moisturizing module, and a phototherapy module.

[0065] Understandably, essential oils are concentrated essences extracted from plants, rich in vitamins and nutrients, and have multiple benefits such as nourishing, moisturizing, repairing, and balancing scalp oil. When the essential oil hair care module is used in conjunction with a hair dryer, it can evenly release the essential oil essence onto the hair by rotating the nozzle 200 degrees.

[0066] During the blow-drying process, the essential oil hair care module automatically releases an appropriate amount of essential oil ingredients. These ingredients can deeply nourish the hair follicles, replenish the nutrients needed by the hair, activate hair follicle cells, and promote hair growth and repair.

[0067] The ionic hair care module utilizes the properties of ionic technology to provide deep care and nourishment to the hair. The types of ions include, but are not limited to, negative ions, water ions, and electro-ions. Negative ions help close the hair cuticles, effectively locking in moisture and preventing water loss, making hair smoother and shinier. Negative ions also neutralize static electricity in the hair, reducing frizz and tangles caused by static, making hair easier to comb and manage.

[0068] The hydration module moisturizes the hair, helping to keep it hydrated and moisturized, reducing dryness and static electricity, and making it softer and smoother. The light therapy module uses LED light therapy technology to emit specific wavelengths of light onto the hair, promoting scalp and hair health, and also helping to reduce dandruff, hair loss, and enhance hair shine.

[0069] According to an embodiment of the present invention, reference Figure 2 As shown, there are multiple hair care components 900, and the multiple hair care components 900 are arranged at radial intervals along the rotating nozzle 200.

[0070] It is understood that in this embodiment, by arranging multiple hair care components 900 at radial intervals along the rotating nozzle 200, it can be ensured that the hair care product can be more comprehensively covered on the hair during the rotation of the nozzle. The arrangement of multiple hair care components 900 allows the hair care product to be more evenly distributed on the hair, avoiding situations where there is too much or too little hair care product in certain areas.

[0071] Different people have different hair types and hairstyles, and therefore different needs for hair care products. The multiple hair care parts 900 can be adjusted according to individual needs. For example, users with thick or curly hair can use more hair care parts 900 to achieve better care results.

[0072] The hair care components 900 in different locations can be equipped with the same hair care products or different hair care products, providing users with a more personalized and diversified hair care experience and achieving precise and efficient hair care results.

[0073] According to one embodiment of the present invention, referring to Figures 1-3 As shown, a receiving cavity 102 is formed in the middle of the rotating nozzle 200, and the hair care component 900 is installed in the receiving cavity 102; and / or, the rotating nozzle 200 is provided with a grille component 230, and the hair care component 900 is provided on the grille component 230.

[0074] In an alternative embodiment, by forming a receiving cavity 102 in the middle of the rotating nozzle 200, the hair care component 900 can be more securely installed on the hair dryer. This design not only ensures the stability of the hair care component 900 during the blow-drying process, but also makes it more convenient to replace or clean the hair care component 900. Users can easily disassemble and install the hair care component 900 as needed, improving the ease of use.

[0075] In another alternative embodiment, the hair care component 900 is disposed on the grille component 230, which can evenly disperse the airflow to ensure balanced airflow during blow-drying. By disposing the hair care component 900 on the grille, the hair care product can be effectively sprayed onto the hair with a uniform airflow, achieving a more even and comprehensive care effect.

[0076] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, the grille component 230 includes multiple grille plates 2301 arranged side by side, and at least one grille plate 2301 is provided with a mounting groove 2302 for installing the hair care component 900.

[0077] Understandably, in this embodiment, the multiple side-by-side grille plates 2301 effectively expand the airflow outlet area of ​​the hair dryer, resulting in a more uniform airflow distribution and improved drying effect. An mounting groove 2302 is provided on at least one grille plate 2301, facilitating the installation of the hair care component 900. This design allows the hair care component 900 to be securely fixed to the grille plate 2301, ensuring the stability and safety of the hair care component 900 during drying. Users can choose the position of the grille plate 2301 where the hair care component 900 is installed to achieve personalized hair care effects.

[0078] The edges of the mounting slot 2302 can be designed with an anti-slip structure, such as raised edges or textures, to increase friction with the hair care component 900 and prevent the hair care component 900 from sliding or shifting during use. When installing the hair care component 900, the user simply aligns it with the mounting slot 2302 and then gently pushes or snaps it in. This installation method is simple and quick, requiring no additional tools or accessories, thus reducing the difficulty of use for the user.

[0079] It is understandable that the mounting slot 2302 can be set on the side of the grille plate 2301 facing the user or on the side of the grille plate 2301. When the mounting slot 2302 is set on the side of the grille plate 2301 facing the user, the user can see the installation position of the hair care component 900 intuitively, which is convenient for installation and disassembly operations. It is also conducive to the even distribution of the hair care component 900, so that the hair care product can cover the hair more comprehensively.

[0080] On the other hand, placing the mounting slot 2302 on the side of the grille 2301 reduces the space occupied on the front of the grille 2301, making the hair dryer's appearance more concise and aesthetically pleasing. Simultaneously, the side mounting slot 2302 also prevents users from accidentally touching the hair care component 900 during use, improving safety. Furthermore, this design allows the grille 2301 to maintain a smooth surface on the front, reducing the risk of hair getting stuck.

[0081] By designing mounting slots 2302 and hair care components 900 with different shapes, sizes, and functions, users can easily replace the hair care components 900 mounted on the grille plate 2301 to suit different hair types, hairstyles, and hair care needs. This flexibility allows the hair dryer to meet the needs of more users, and the hair care components 900 can be easily disassembled and installed, enabling users to easily perform cleaning and maintenance, and extending the life of the hair dryer.

[0082] According to one embodiment of the present invention, referring to Figure 2 and Figure 8 As shown, at least one grille plate 2301 is rotatably disposed on the rotating nozzle 200, and the hair care component 900 is mounted on the rotatable grille plate 2301.

[0083] In this embodiment, the rotatable grid plate 2301 allows the hair care component 900 to adjust its position as the grid plate 2301 rotates, thereby achieving all-round hair care. The hair care product can be sprayed more evenly on the hair, avoiding the situation of too much or too little hair care product in some areas, thus improving the hair care effect.

[0084] Furthermore, mounting the hair care component 900 onto the rotatable grille 2301 facilitates user replacement and cleaning. Because the grille 2301 can rotate, users can more easily install and remove the hair care component 900 for cleaning or replacement. When the grille 2301 rotates, it also creates more airflow gaps at different angles and positions, effectively expanding the airflow area of ​​the hair dryer.

[0085] According to an embodiment of the present invention, reference Figure 5 and Figure 6 As shown, the centerline of the air outlet of the rotating nozzle 200 is aligned with the centerline of the mounting base 110. This alignment ensures that wind or airflow can be blown directly and unobstructed from the nozzle, reducing energy loss and waste and improving energy efficiency. Secondly, this design also enhances the safety and stability of the system. Because the wind or airflow can be blown directly in a straight line, energy dispersion or instability caused by deviation from the centerline during transmission is avoided, thus reducing potential safety hazards.

[0086] In another alternative implementation, refer to Figures 1-3 As shown, the air outlet 201 of the rotary nozzle 200 is eccentrically positioned relative to the mounting base 110. When the rotary nozzle 200 rotates, the air outlet 201 of the rotary nozzle 200 is adapted to rotate around the central axis of the mounting base 110.

[0087] It is understood that in this embodiment, the eccentric setting of the air outlet 201 of the rotating nozzle 200 relative to the mounting base 110 can be understood as the center point of the air outlet 201 not coinciding with the central axis of the mounting base 110, having a certain offset, so that when the rotating nozzle 200 rotates, the air outlet 201 can rotate around the central axis of the mounting base 110, thereby realizing flexible adjustment of the blowing area.

[0088] When the nozzle rotates, the hair care component 900 moves to different positions. Due to the off-center setting of the air outlet 201, the hair care component 900 can accurately spray the hair care product onto the hair in that area when it moves to each position, thereby achieving a more comprehensive and even hair care effect.

[0089] It should be noted that the air outlet 201 of the rotary nozzle 200 can be a regular shape. For example, when the air outlet 201 of the rotary nozzle 200 is circular, the center point of the air outlet 201 is the center of the circle; when the air outlet 201 of the rotary nozzle 200 is elliptical, the center point of the air outlet 201 is the center point of the ellipse. Of course, the air outlet 201 of the rotary nozzle 200 can also be other irregular shapes. This invention does not impose specific limitations on the shape of the air outlet 201 of the rotary nozzle 200. Irregular shapes also have a geometric center point, which will not be elaborated here.

[0090] It should be noted that the straight line passing through the center point of the air outlet 201 and perpendicular to the air outlet 201 is the central axis of the air outlet 201. The central axis of the rotating nozzle 200 and the central axis of the mounting base 110 can be parallel, intersecting, or not intersecting. The relationship between the central axis of the air outlet 201 and the central axis of the mounting base 110 is a geometric relationship in a mathematical sense, which will not be elaborated here.

[0091] For example, when the central axis of the air outlet 201 and the central axis of the mounting base 110 are parallel to each other, the rotating nozzle 200 can maintain a stable blowing effect during rotation. The overall direction of the airflow blown from the air outlet 201 is parallel to the axial direction of the central axis of the mounting base 110, thereby maintaining the continuity and stability of the blowing. Furthermore, when the central axis of the air outlet 201 is parallel to the central axis of the mounting base 110, the stability of the entire nozzle assembly can be improved, reducing the swaying and shaking of the rotating nozzle 200 during rotation and ensuring a smoother blowing process.

[0092] For example, when the central axis of the air outlet 201 intersects with the central axis of the mounting base 110, a wider range of rotation can be achieved. This design allows the air outlet 201 to rotate within a larger angle range, meeting the user's needs for various blowing angles. The intersecting arrangement enables the air outlet 201 to blow air at multiple angles in both vertical and horizontal directions. Users can adjust the blowing direction by rotating the nozzle 200, achieving a more precise and personalized blowing effect. The intersecting arrangement of the central axis of the air outlet 201 and the central axis of the mounting base 110 increases the flexibility of the air outlet 201's rotation, allowing users to freely adjust the angle of the air outlet 201 as needed to meet different blowing requirements and improve ease of use. The intersecting arrangement also makes better use of space, resulting in a more compact design for the entire nozzle assembly, saving space and making it suitable for various sizes of blower devices.

[0093] For example, a wider range of rotation can be achieved when the central axis of the air outlet 201 and the central axis of the mounting base 110 do not intersect, which will not be elaborated here.

[0094] In one embodiment, the eccentricity angle of the rotating nozzle 200 is adjustable, allowing the central axis of the air outlet 201 and the central axis of the mounting base 110 to switch from parallel to intersecting or non-intersecting, or vice versa. This allows the user to adjust the air outlet area of ​​the rotating nozzle 200 according to their needs.

[0095] In one embodiment, the eccentricity of the rotating nozzle 200 is adjustable, making the distance between the central axis of the air outlet 201 and the central axis of the mounting base 110 adjustable. Users can adjust the air outlet area according to their own needs, thereby improving the convenience of use.

[0096] According to one embodiment of the present invention, referring to Figure 2 and Figure 3 As shown, the mounting base 110 and the rotary nozzle 200 are connected by a bearing 500. One of the mounting base 110 and the rotary nozzle 200 is provided with a mounting hole 160. The outer ring of the bearing 500 is mounted in the mounting hole 160, and the inner ring of the bearing 500 is connected to the other of the mounting base 110 and the rotary nozzle 200.

[0097] Understandably, the rotatable connection between the base and the rotating nozzle 200 via the bearing 500 effectively reduces friction between them, lowers energy loss, and helps ensure smooth rotation of the nozzle 200 relative to the base. As the core component connecting the base and the nozzle 200, the bearing 500 provides smooth rotational movement, allowing the nozzle 200 to rotate easily on the base without jamming or poor friction. It also provides stable support, ensuring the nozzle 200 remains stable during rotation, preventing wobbling or instability and guaranteeing safe use of the hair dryer.

[0098] In one embodiment, a capping screw 600 is also included for securing the bearing 500 to the base.

[0099] According to one embodiment of the present invention, referring to Figures 1-3 As shown, it also includes a housing 120, a mounting base 110 connected to the housing 120, a mounting cavity 101 formed between the mounting base 110 and the housing 120, and a rotating nozzle 200 is at least partially disposed in the mounting cavity 101.

[0100] In some implementations, reference Figure 3 and Figure 4 As shown, a housing 120 is also provided, which can be placed on the base and the rotating nozzle 200 is placed inside the housing 120 to effectively protect the rotating nozzle 200 from the influence of the external environment, such as dust and moisture, thereby extending the service life of the rotating nozzle 200, reducing the risk of users accidentally coming into contact with the rotating nozzle 200, and enhancing the aesthetic effect, making the hair dryer look cleaner and more beautiful.

[0101] In an optional embodiment, the rotary nozzle 200 is partially disposed within the mounting cavity 101, with its outlet 201 extending out of the mounting cavity 101. Because the outlet 201 extends out of the mounting cavity 101, its size and shape are not limited by the mounting cavity 101, allowing for a larger airflow area. This design helps to increase airflow and improve blowing efficiency.

[0102] Of course, the rotating nozzle 200 can also be entirely located within the mounting cavity 101. The mounting cavity 101 can provide protection for the rotating nozzle 200 and prevent users from accidentally touching the rotating nozzle 200.

[0103] It should be noted that the rotating nozzle 200 can be either an eccentric design as described in the above embodiments or a non-eccentric design as described in the following embodiments.

[0104] According to one embodiment of the present invention, please refer to Figures 4 to 8It includes a mounting base 100 and a rotating nozzle 200. The rotating nozzle 200 is rotatably connected to the mounting base 100. The air outlet 201 of the rotating nozzle 200 is provided with a grille component 230. The grille component 230 includes a first grille portion 231. The first grille portion 231 is adapted to drive the rotating nozzle 200 to rotate relative to the mounting base 100 under the push of airflow.

[0105] According to an embodiment of the present invention, the nozzle assembly of the hair dryer allows the rotating nozzle 200 to rotate relative to the mounting base 100 during use, effectively expanding the blowing area of ​​the hair dryer and covering a wider area. Due to the increased blowing area, users can dry their hair faster, saving time and improving drying efficiency.

[0106] It should be noted that the present invention does not impose specific limitations on the structure of the mounting base 100. The rotating nozzle 200 can be disposed above the mounting base 100 or inside the mounting base 100. By rotating the nozzle 200 and connecting it to the mounting base 100, multi-angle adjustment of the nozzle assembly is achieved, allowing the airflow direction of the hair dryer to be flexibly adjusted according to user needs, thus increasing ease of use.

[0107] Understandably, the grille component 230 can guide and disperse the airflow blown from the air outlet 201, while utilizing the dynamic characteristics of the airflow to achieve automatic rotation of the rotary nozzle 200. When the airflow passes through the first grille section 231, the first grille section 231 can generate sufficient rotational torque to drive the rotary nozzle 200 to rotate.

[0108] Understandably, the grille plates of the first grille section 231 are specially designed to generate sufficient torque when airflow passes through, driving the rotary nozzle 200 to rotate. In this embodiment, the grille plates of the first grille section 231 are all inclined clockwise at the air outlet 201 of the rotary nozzle 200. Of course, the grille plates of the first grille section 231 can also be inclined counterclockwise at the air outlet 201 of the rotary nozzle 200. The fact that the grille plates of the first grille section 231 are all inclined in the same direction helps to form a rotational torque in the same direction, thereby generating a rotational driving force.

[0109] The present invention does not limit the number of grid plates in the first grid section 231. The number of first grid plates 231 can be one or more.

[0110] Understandably, the grille component 230 can consist only of the first grille section 231, resulting in a simpler overall structure, reduced manufacturing difficulty, and easier assembly and maintenance. Of course, the grille component 230 can also include grille areas with other functions, such as the second grille section 232 mentioned later. When the grille component 230 consists only of the first grille section 231, the first grille section 231 can cover the air outlet 201 of the rotating air nozzle 200. When the grille component 230 includes grille areas with other functions, the number of first grille sections 231 can be one or more. When there are multiple first grille sections 231, they can be arranged adjacent to each other at the air outlet 201, or opposite each other at the air outlet 201.

[0111] According to one embodiment of the present invention, please refer to Figures 8 to 10 When there are multiple first grille sections 231: the multiple first grille sections 231 are symmetrically distributed along the rotation axis of the rotating nozzle 200. It is understood that the symmetrical distribution of the first grille sections 231 along the rotation axis of the rotating nozzle 200 ensures that the airflow is balanced as it passes through the grille component 230. This balanced airflow distribution helps reduce airflow turbulence, making the rotating nozzle 200 more stable during rotation. Due to the balanced airflow, the airflow of the hair dryer can be more evenly distributed in all directions, helping to improve the blowing effect. Furthermore, the centrally symmetrical distribution of the first grille sections 231 can more effectively utilize the power of the airflow to generate a larger rotational torque, thereby driving the rotating nozzle 200 to rotate with higher efficiency. In addition, the centrally symmetrical design is more visually appealing and harmonious, making the hair dryer nozzle assembly more attractive in appearance.

[0112] In this embodiment, there are two first grille sections 231, and the two corresponding first grille sections 231 are symmetrically arranged at both ends of the grille component 230.

[0113] When there are multiple first grille sections 231, their distribution can be varied, such as quadrilateral distribution, opposite sides arrangement, or adjacent sides arrangement. Of course, when there are multiple first grille sections 231, they can also be arranged in other ways at the air outlet 201, as long as the rotating nozzle 200 can rotate autonomously when the airflow passes through.

[0114] According to one embodiment of the present invention, please refer to Figures 8 to 10The grille component 230 also includes a second grille portion 232, and a first grille portion 231 is disposed on the outside of the second grille portion 232. The first grille portion 231 and the grille plate in the second grille portion 232 are set at an angle to each other in their extending directions.

[0115] Understandably, by setting up a first grille section 231 and a second grille section 232, and angled their extension directions, multi-layered airflow control can be achieved. The first grille section 231 is primarily responsible for driving the rotating nozzle 200 to rotate under the influence of airflow, while the second grille section 232 can be used to further optimize airflow distribution, reduce noise, or provide specific blowing effects (for example, as mentioned later, the second grille section 232 may contain hair care products). This multi-layered design makes airflow control more flexible, thus meeting the needs of different users.

[0116] Understandably, since the first grille portion 231 is located outside the second grille portion 232, it helps to better utilize the dynamic characteristics of the airflow, enabling the rotating nozzle 200 to obtain a greater rotational torque and thus rotate more smoothly.

[0117] In one embodiment, please refer to Figure 8 The extension directions of the grating plates of the first grating section 231 and the grating plates of the second grating section 232 are perpendicular to each other.

[0118] Of course, the angle between the extending directions of the grid plate of the first grid section 231 and the grid plate of the second grid section 232 can be other values, such as 30°, 60° and 90°.

[0119] According to one embodiment of the present invention, please refer to Figure 8 When there are two first grille sections 231: a second grille section 232 is disposed between the two first grille sections 231.

[0120] Understandably, the first grille section 231, which serves as the drive, is located on both sides of the second grille section 232, which allows the rotating nozzle 200 to obtain a greater rotational torque. This effectively balances and optimizes the airflow distribution from the blower outlet 201. The second grille section 232 can further disperse and guide the airflow, preventing the airflow from becoming too concentrated or sparse in certain areas.

[0121] Since the second grille section 232 is located between the two first grille sections 231, it can act as a bridge to connect the two first grille sections 231, which helps to reduce the shaking and instability of the rotating nozzle 200 during rotation and improve the smoothness and stability of rotation.

[0122] According to one embodiment of the present invention, the tilt angle of the grille plate of the first grille section 231 is adjustable. It is understood that by adjusting the tilt angle of the grille plate of the first grille section 231, the user can adjust the rotational speed of the rotating nozzle 200. For example, when the tilt angle of the grille plate of the first grille section 231 is small (excluding the case where the tilt angle is 0), the rotating nozzle 200 receives a larger driving force and rotates at a faster speed; when the tilt angle of the grille plate is large, the rotating nozzle 200 receives a smaller driving force and rotates at a slower speed.

[0123] It should be noted that the tilt angle here can be understood as the angle between the grille and the plane where the air outlet 201 is located. In one embodiment, the grille of the first grille section 231 is tangent to the air guide channel; in other words, the tilt angle of the grille of the first grille section 231 is 0, and the rotating nozzle 200 will not rotate at this time.

[0124] In one embodiment, the angle between the grille plate of the first grille section 231 and the air outlet 201 is 90°. At this time, the air outlet 200 can be vented smoothly without causing the air outlet 200 to rotate.

[0125] It should be noted that the grille plate of the first grille section 231 not only drives the rotating nozzle 200 to rotate, but also functions as an air outlet. The adjustable tilt angle of the grille plate allows users to easily adjust the wind speed and rotation effect during airflow. Without replacing the nozzle or adjusting other complex settings, users can achieve the desired effect simply by adjusting the tilt angle of the grille plate. This convenience not only enhances the user experience but also reduces operational complexity.

[0126] According to one embodiment of the present invention, the tilt angle of the grille plate of the second grille section 232 is adjustable. It is understood that the user can adjust the angle of the grille plate according to actual needs, thereby changing the direction and distribution of airflow. Whether concentrated airflow is needed for localized styling or even airflow is desired for quick hair drying, this can be achieved by adjusting the angle of the grille plate. This design makes the hair dryer more flexible and practical, adaptable to the drying needs of different users. For example, when the tilt angle of the grille plate of the second grille section 232 is smaller, the airflow is more concentrated, suitable for localized styling or strong airflow drying; while when the angle of the grille plate is larger, the airflow is more dispersed, suitable for even airflow or gentle conditioning. This adjustability allows users to select the optimal drying effect according to their hair type, hairstyle, and drying purpose.

[0127] According to one embodiment of the present invention, please refer to Figures 11 to 13The first grille section 231 includes several grille plates, each of which includes a first arc-shaped structure 233 and a second arc-shaped structure 234. The first arc-shaped structure 233 and the second arc-shaped structure 234 are respectively disposed on both sides of the rotating shaft of the rotating nozzle 200, and the first arc-shaped structure 233 and the second arc-shaped structure 234 face opposite directions, with a smooth transition connection between them. When airflow acts on the first arc-shaped structure 233 and the second arc-shaped structure 234, due to the different tangential angles of the first arc-shaped structure 233 and the second arc-shaped structure 234 of the several grille plates, the airflow interacts with the grille to generate a driving force in a counterclockwise or clockwise direction, thereby driving the grille to rotate.

[0128] It should be noted that the first arc-shaped structure 233 and the second arc-shaped structure 234 are respectively located on both sides of the rotating shaft of the rotary nozzle 200. Please refer to... Figure 11 The pivot is located at the cross intersection position shown in the figure, and the first arc structure 233 and the second arc structure 234 are respectively set on opposite sides of the pivot.

[0129] It should be noted that the first arc-shaped structure 233 and the second arc-shaped structure 234 face opposite directions, that is, the opening of the first arc-shaped structure 233 faces opposite directions to the opening of the second arc-shaped structure 234. For example, when the opening of the first arc-shaped structure 233 faces downward, the opening of the second arc-shaped structure 234 faces upward; when the opening of the first arc-shaped structure 233 faces left, the opening of the second arc-shaped structure 234 faces right, and so on.

[0130] In one embodiment, the first arc-shaped structure 233 and the second arc-shaped structure 234 have the same curvature. It is understood that the same curvature ensures that the airflow characteristics generated by the grille plate during rotation are consistent between the first arc-shaped structure 233 and the second arc-shaped structure 234, guaranteeing rotational stability.

[0131] Of course, the curvature of the first arc structure 233 and the second arc structure 234 can also be different. Through differentiated design, different airflow effects can be generated, thereby controlling the air outlet effect of the rotating nozzle 200. The specific curvature can be designed according to the actual situation to meet the ventilation needs of a specific area.

[0132] In one embodiment, the first arc-shaped structure 233 and the second arc-shaped structure 234 are symmetrical about the rotation axis of the rotating nozzle 200. It is understood that because the first arc-shaped structure 233 and the second arc-shaped structure 234 are symmetrical about the rotation axis of the rotating nozzle 200, the airflow will be more evenly distributed on both sides, reducing the asymmetrical pressure generated during airflow.

[0133] Of course, the first arc-shaped structure 233 and the second arc-shaped structure 234 can also be asymmetrically arranged on both sides of the rotating shaft of the rotary nozzle 200. Asymmetrical arrangement can generate airflow in different directions and speeds. Similarly, through differentiated design, different airflow effects can be generated, thereby controlling the air outlet effect of the rotary nozzle 200.

[0134] In one embodiment, the curvature of the first arc structure 233 or the second arc structure 234 of any two adjacent grille plates can be the same. The air outlet effect produced by the first arc structure 233 or the second arc structure 234 with the same curvature is relatively similar, making the airflow more consistent.

[0135] Of course, the curvature of the first arc structure 233 or the second arc structure 234 of any two adjacent grid plates may also be different, and no specific restrictions are imposed here.

[0136] In one embodiment, the chordal tangent of the arc surface of the first arc structure 233 or the second arc structure 234 of any two adjacent grilles forms the same angle with the cross-section of the air outlet 201. This ensures that airflow through two adjacent grilles occurs at similar angles, resulting in a unified airflow direction and improved user experience.

[0137] Of course, the angle between the chordal surface of the first arc structure 233 or the second arc structure 234 of any two adjacent grilles and the cross-section of the air outlet 201 can also be different. By flexibly setting the angle, the impact of the ventilation system on air quality can be controlled more effectively. For example, the angle between the chordal surface of the grille near the center of rotation and the cross-section of the air outlet 201 is larger, allowing the air near the center of rotation to flow outward at a larger angle, while the angle between the chordal surface of the grille away from the center of rotation and the cross-section of the air outlet 201 is smaller, allowing the air away from the center of rotation to cover other corners.

[0138] In one embodiment, please refer to Figures 11 to 13 The included angle between any two adjacent grille plates closer to the center of the air outlet 201 is greater than the included angle between the grille plates farther from the center of the air outlet 201. The included angle is the angle between the chordal surface of the arcuate structure 233 or the second arcuate structure 234 and the cross-section of the air outlet 201. That is, the angle between the chordal surface of the arcuate structure 233 or the second arcuate structure 234 of any two adjacent grille plates and the cross-section of the air outlet 201 decreases from the center of the air outlet 201 towards both ends.

[0139] It should be noted that, please refer to Figure 12The angle between the second arc-shaped structure 234 (the DD cross-sectional view in the figure is the cross-sectional view of the second arc-shaped structure 234) closer to the center of the air outlet 201 and the cross-section of the air outlet 201 is the largest, and the angle between the second arc-shaped structure 234 further away from the center of the air outlet 201 and the cross-section of the air outlet 201 gradually decreases. Similarly, the angle between the first arc-shaped structure 233, corresponding to the second arc-shaped structure 234, and the cross-section of the air outlet 201 also decreases from the center of the air outlet 201 towards both ends.

[0140] According to one embodiment of the present invention, a magnetic suction component 300 is further included, which is disposed on the side of the mounting base 100 facing away from the air outlet 201. It is understood that the magnetic suction component 300 makes the connection between the mounting base 100 and other related components or surfaces more convenient. Utilizing the principle of magnetic adsorption, the mounting base 100 can be easily fixed without the need for traditional fixing methods such as screws or clips. Similarly, disassembly becomes simple and quick; separation can be achieved simply by overcoming magnetic force, greatly improving the convenience of operation.

[0141] The nozzle assembly of the hair dryer according to an embodiment of the present invention is described in reference to... Figure 5 , Figures 14 to 15 The nozzle assembly includes a housing 120, a mounting base 110, a rotating nozzle 200, a first damping component 710, and a first adjusting component 720. The housing 120 has an internal mounting cavity 101; the mounting base 110 is at least partially located within the mounting cavity 101; the rotating nozzle 200 is located within the mounting cavity 101 and rotatably connected to the mounting base 110; the first damping component 710 is located between the housing 120 and the rotating nozzle 200; and the first adjusting component 720 is connected to the first damping component 710 and is used to adjust the rotational resistance of the first damping component 710.

[0142] According to an embodiment of the hair dryer nozzle assembly of the present invention, the rotating nozzle 200 can rotate relative to the mounting base 110 during use, effectively expanding the air-blowing area of ​​the hair dryer and covering a wider area. Due to the increased air-blowing area, users can dry their hair faster, saving time and improving drying efficiency. The first damping component 710 provides rotational resistance between the rotating nozzle 200 and the housing 120. Through the adjustment action of the first adjusting component 720, the magnitude of the rotational resistance of the first damping component 710 can be adjusted, thereby controlling the rotational speed of the rotating nozzle 200. This allows users to obtain a larger air-blowing area while also meeting the different speed requirements of various users.

[0143] It should be noted that rotational resistance can be friction, electromagnetic resistance, etc.

[0144] Understandably, the mounting base 110 is used to mount and support the rotary nozzle 200. The rotary nozzle 200 can be mounted to the mounting base 110 via the bearing 500 or other rotatable connection, allowing the rotary nozzle 200 to rotate relative to the mounting base 110. The rotatable connection between the rotary nozzle 200 and the mounting base 110 enables multi-angle adjustment of the nozzle assembly, allowing the blower's airflow direction to be flexibly adjusted according to user needs, increasing ease of use.

[0145] Understandably, the first damping component 710 primarily provides friction between the rotating nozzle 200 and the housing 120. The adjusting component can control the rotation speed of the rotating nozzle 200 by adjusting the friction between the first damping component 710 and the rotating nozzle 200, or by adjusting the friction between the first damping component 710 and the housing 120, allowing users to adjust the blowing effect according to their needs.

[0146] It should be noted that the first damping component 710 can be a commercially available shock absorber, spring damper, or friction plate, as long as it can provide sufficient friction. This invention does not impose specific limitations on this. The first adjusting component 720 can be a commercially available lifting screw, telescopic rod, or elastic element, as long as it can change the length direction. This invention does not impose specific limitations on this. Any combination of the first damping component 710 and the first adjusting component 720 is within the protection scope of this invention.

[0147] Of course, the first damping component 710 can also be a commercially available electromagnet capable of changing magnetic resistance. This is prior art and will not be described further in this application.

[0148] It should be noted that the rotational power of the rotary nozzle 200 can be generated when the airflow passes by (an embodiment of generating power is described later), or it can be generated by a motor drive. This invention does not impose specific limitations on the rotational power of the rotary nozzle 200.

[0149] In one embodiment, the first end of the first damping component 710 is connected to one of the housing 120 and the rotary nozzle 200, the second end of the first damping component 710 abuts against the other, and the pressure of the second end of the first damping component 710 is adjustable. When the pressure of the second end of the first damping component 710 increases, the frictional force provided by the first damping component 710 increases, and when the pressure of the second end of the first damping component 710 decreases, the frictional force provided by the first damping component 710 decreases.

[0150] According to one embodiment of the present invention, there are multiple first damping components 710, which are spaced apart on the outer periphery of the rotating nozzle 200.

[0151] It is understandable that by spaced-apart first damping components 710, multiple friction points can be formed on the outer periphery of the rotary nozzle 200, thereby increasing the damping effect. The spaced-apart damping components can be flexibly adjusted according to usage requirements. For example, when a larger damping force is required, the number of damping components can be increased or their distribution density can be adjusted; when a smaller damping force is required, the number of damping components can be reduced or their spacing can be adjusted.

[0152] According to one embodiment of the present invention, the number of first damping components 710 is one, which is arranged around the outer periphery of the rotating nozzle 200.

[0153] Understandably, the single damping component encircling the outer periphery of the rotary nozzle 200 simplifies the overall structure of the nozzle assembly, reduces the number of parts and assembly steps, lowers production costs, and also improves product reliability and stability. The encircling damping component forms a continuous friction surface around the outer periphery of the rotary nozzle 200, providing uniform damping force and ensuring more even force distribution during rotation.

[0154] According to one embodiment of the present invention, please refer to Figure 14 and Figure 15 The first adjusting component 720 is provided with an adjusting rail 721. When the first adjusting component 720 is installed to one of the housing 120 and the rotary nozzle 200, the extending direction of the adjusting rail 721 is toward the other of the housing 120 and the rotary nozzle 200. The first end of the first damping component 710 is connected to the adjusting rail 721.

[0155] It is understandable that the damping effect can be adjusted by adjusting the position of the damping component on the adjustment track 721, thereby adjusting the distance between the first mating part 210 and the second mating part 130.

[0156] It should be noted that the extension direction of the adjustment track 721 is towards the housing 120 or the rotating nozzle 200. This orientation can be vertical or at an angle. For example, the adjustment track 721 can be at a 45° angle to the tangent of the rotating nozzle 200.

[0157] According to one embodiment of the present invention, please refer to Figures 4 to 8 The rotary nozzle 200 is provided with a first mating part 210. The mounting base 110 includes a base body 140 and a second mating part 130. The base body 140 is connected to the second mating part 130. The second mating part 130 is located at the center of the base body 140. The first mating part 210 passes through the mounting hole 131 of the second mating part 130.

[0158] Understandably, the second mating part 130 can form a cavity for receiving the hair care component. By placing the second mating part 130 at the center of the base 140, the structure of the entire mounting base 110 becomes more compact. The first mating part 210 passes through the mounting hole 131 of the second mating part 130. This through-hole design not only simplifies the assembly process but also enhances the connection stability between the rotary nozzle 200 and the mounting base 110.

[0159] According to one embodiment of the present invention, please refer to Figures 4 to 8 It also includes a capped screw, the first mating part 210 is provided with a threaded hole, the opening of the threaded hole faces away from the air outlet 201 of the rotating nozzle 200, and the capped screw is provided in the threaded hole so that the end face of the threaded hole opening is flush with the end face of the second mating part 130.

[0160] Understandably, the capped screw, through its threaded connection with the threaded hole of the first mating part 210, forms a robust connection. This connection not only enhances the connection strength between the rotary nozzle 200 and the mounting base 110, but also improves the structural stability of the entire nozzle assembly.

[0161] According to one embodiment of the present invention, please refer to Figures 4 to 8 The base 140 has a snap-fit ​​interface 141 on its outer periphery, and the outer shell 120 has a snap-fit ​​part 121, which engages with the snap-fit ​​interface 141. Understandably, this snap-fit ​​design between the mounting base 110 and the outer shell 120 makes assembly between them very simple and quick. The user simply aligns the snap-fit ​​part 121 of the outer shell 120 with the snap-fit ​​interface 141 and gently snaps it in place to complete the assembly process. This design not only reduces the difficulty of assembly but also improves assembly efficiency.

[0162] According to one embodiment of the present invention, please refer to Figures 4 to 8 It also includes a bottom cover 400, which is detachably mounted on the mounting base 110. The detachable design of the bottom cover 400 makes it easier to replace or upgrade components inside the mounting base 110. For example, the magnetic component 300 mentioned later can be easily replaced by removing the bottom cover 400 without disassembling the entire nozzle assembly.

[0163] According to one embodiment of the present invention, please refer to Figure 5 and Figure 16 It also includes a second damping component 810 and a second adjusting component 820. The second damping component 810 is disposed between the mounting base 110 and the rotary nozzle 200. The second adjusting component 820 is connected to the second damping component 810 and is used to adjust the rotational resistance of the second damping component 810.

[0164] Understandably, the second damping component 810 primarily serves to provide rotational resistance between the rotary nozzle 200 and the mounting base 100. The second adjusting component 820 changes the distance between the mounting base 100 and the rotary nozzle 200, thereby altering the magnitude of the rotational resistance of the second damping component 810 and controlling the rotational speed of the rotary nozzle 200. Users can adjust the blowing effect according to their needs.

[0165] It should be noted that the second damping component 810 can be a commercially available shock absorber, spring damper, or friction plate, as long as it can provide sufficient friction. This invention does not impose specific limitations on this. The second adjusting component 820 can be a commercially available lifting screw, telescopic rod, or elastic element, as long as it can change the length direction. This invention does not impose specific limitations on this. Any combination of the second damping component 810 and the second adjusting component 820 is within the protection scope of this invention.

[0166] Of course, the second damping component 810 can also be a commercially available electromagnet capable of changing magnetic resistance. This is prior art and will not be described further in this application.

[0167] It should be noted that the rotational power of the rotary nozzle 200 can be generated when the airflow passes by (an embodiment of generating power is described later), or it can be generated by a motor drive. This invention does not impose specific limitations on the rotational power of the rotary nozzle 200.

[0168] It is understood that as the rotational resistance provided by the second damping component 810 increases, the rotational speed of the rotating nozzle 200 decreases; as the rotational resistance provided by the second damping component 810 decreases, the rotational speed of the rotating nozzle 200 increases; when the rotational resistance provided by the second damping component 810 is sufficiently large, the rotating nozzle 200 stops rotating, and can be considered as the rotating nozzle 200 being fixed to the mounting base 100. The nozzle assembly of the present invention is described below with reference to an embodiment:

[0169] When a user uses a hair dryer with this nozzle assembly, the rotating nozzle 200 can rotate relative to the mounting base 100, thereby increasing the airflow area. If the user feels that the airflow area of ​​the rotating nozzle 200 is too large, the second adjustment component 820 can be adjusted to slow down the rotation speed of the rotating nozzle 200. When the user does not need the rotating nozzle 200 to rotate, the rotational resistance of the second damping component 810 can be adjusted to the maximum, and the rotating nozzle 200 will stop rotating.

[0170] According to one embodiment of the present invention, the rotary nozzle 200 is provided with a first mating part 210, and the mounting base 100 includes a seat body 140 and a second mating part 130 connected to each other. The second mating part 130 is disposed at the center of the seat body 140, and the second damping member 810 is disposed between the first mating part 210 and the second mating part 130.

[0171] Understandably, by placing the second damping component 810 between the first mating part 210 and the second mating part 130, the contact area between the second damping component 810 and the rotary nozzle 200 and the mounting base 100 is increased, ensuring that the second damping component 810 exerts its maximum effect when the rotary nozzle 200 rotates. The second adjusting component 820 can effectively adjust the friction force of the second damping component 810 by changing the distance between the first mating part 210 and the second mating part 130.

[0172] According to one embodiment of the present invention, please refer to Figure 5 and Figure 16 The second adjusting component 820 includes a threaded knob, and the center of the second mating part 130 is provided with a threaded hole. The threaded knob passes through the first mating part 210 and is connected to the threaded hole, which is suitable for adjusting the distance between the first mating part 210 and the second mating part 130.

[0173] Understandably, by rotating the threaded knob, the distance between the first mating part 210 and the second mating part 130 can be precisely adjusted, thereby achieving fine adjustment of the friction force of the second damping component 810. The threaded connection makes the adjustment process stable and reliable, preventing slippage or loosening and ensuring the durability of the adjustment effect.

[0174] In this embodiment, the head of the threaded knob that the user can rotate is located on one side of the air outlet 201, and the threaded rod of the threaded knob is connected to the threaded hole of the second mating part 130. The user can adjust the first mating part 210 and the second mating part 130 by means of the knob. This operation method is intuitive and easy to understand, and the operation is simple.

[0175] Of course, the head of the threaded knob, which allows the user to rotate it, can also be located in other positions on the nozzle assembly.

[0176] According to one embodiment of the present invention, please refer to Figure 9 The second adjusting component 820 also includes an elastic element, one end of which is connected to the second damping component 810, and the other end of which is connected to the second mating part 130.

[0177] Understandably, the elastic element can provide pressure to the second damping component 810, thereby enabling the second damping component 810 to generate more effective resistance.

[0178] According to one embodiment of the present invention, please refer to Figure 7 The base is provided with a guide section 132 and an air inlet 142. The air inlet 142 is located on the outer periphery of the guide section 132. An air guide section 143 is formed between the outer contour of the guide section 132 and the rotating nozzle 200. The air guide section 143 connects the air outlet 201 and the air inlet 142.

[0179] It is understandable that the air inlet 142 is located on the outer periphery of the guide section 132. The guide section 132 can form a guide effect, guiding the air to flow along the path of the guide section 143, so that the air can flow out from the air outlet 201 in a specific flow direction and speed, which helps to improve the airflow to push the first grille section 231 and drive the rotating nozzle 200 to rotate relative to the base.

[0180] According to one embodiment of the present invention, please refer to Figure 7 Along the direction from the air inlet 142 toward the air outlet 201, the outer contour of the guide portion 132 gradually decreases.

[0181] Understandably, the airflow flows along the outer contour of the guide section 132 to the air outlet 201. As the outer contour of the guide section 132 gradually decreases, the airflow channel becomes wider and the air outlet area becomes larger, making the user feel more comfortable when using the hair dryer.

[0182] It should be noted that the cross-section of the guide section 132 can be circular or other curved shapes; no specific restrictions are imposed here.

[0183] According to one embodiment of the present invention, along the direction from the air inlet 142 toward the air outlet 201, the outer contour of the guide portion 132 first increases and then decreases.

[0184] Understandably, the airflow follows the outer contour of the guide section 132 towards the outlet 201. As the outer contour of the guide section 132 increases, the airflow channel narrows, and the gas velocity increases. Conversely, as the outer contour of the guide section 132 decreases, the airflow channel widens, resulting in a larger gas outlet area. The gas undergoes a compression followed by release process during its flow, thus generating greater airflow and pressure at the outlet 201. This design also reduces turbulence and eddies generated during airflow to some extent, thereby reducing noise generation.

[0185] According to one embodiment of the present invention, please refer to Figure 5 or Figure 13 The base is provided with several air guide blades, which are spaced apart on the base 140 to separate the airflow passing through the guide section 132 and guide it to the rotating nozzle 200.

[0186] Understandably, the airflow through the mounting base 110 can be effectively separated and guided to the rotating nozzle 200 by the air guide vanes 170 on the mounting base 110. With the guidance of the vanes, the airflow can pass through the mounting base 110 more smoothly, reducing resistance loss and thus enhancing the blowing effect.

[0187] According to one embodiment of the present invention, please refer to Figure 13 The guide vane 170 and the grille plate of the first grille section 231 are correspondingly arranged. By correspondingly arranging the guide vane 170 and the grille plate of the first grille section 231, the airflow can be effectively separated and guided to the rotary nozzle 200.

[0188] It should be noted that the guide vane 170 and the grille plate of the first grille section 231 are correspondingly arranged, including corresponding position and / or corresponding shape. Positional correspondence can be understood as the guide vane 170 and the grille plate of the first grille section 231 being positioned in correspondence. For example, the guide vane 170 is positioned directly below the grille plate of the first grille section 231. Of course, the guide vane 170 is not limited to being positioned directly below the grille plate of the first grille section 231; it can also be positioned in other locations, as long as the positional relationship between the guide vane 170 and the grille plate is one-to-one. Corresponding shape can be understood as the tilt angle of the guide vane 170 of the first grille plate being the same as the tilt angle of the first grille plate, and / or the curvature of the guide vane 170 being the same as the curvature of the first grille plate, so that the air guiding direction and air guiding effect of the guide vane 170 and the first grille plate correspond, thereby reducing wind loss.

[0189] According to one embodiment of the present invention, please refer to Figure 5 The mounting base 100 also includes several baffle blades 150. The second mating part 130 is provided with a flow guide part 132. The baffle blades 150 are disposed in the circumference of the flow guide part 132 and are used to connect the flow guide part 132 and the base body 140.

[0190] Understandably, the airflow guide 132 effectively separates and guides the airflow passing through the mounting base 100 to the rotary nozzle 200. The baffle blades 150 connect the central airflow guide 132 and the circumferential base 141, providing mechanical support and improving the stability of the mounting base. The connection between the baffle blades 150 and the base 140 strengthens the overall structure of the base 140, improving its resistance to deformation and impact, helping to ensure that the mounting base 100 maintains stable performance and extends its service life during long-term use.

[0191] According to one embodiment of the present invention, please refer to Figure 5 and Figure 11One of the second mating parts 130 and the rotary nozzle 200 is provided with a mounting hole 160. A bearing 500 is provided in the mounting hole 160. The outer ring of the bearing 500 is mounted in the mounting hole 160, and the inner ring of the bearing 500 is connected to the other of the second mating parts 130 and the rotary nozzle 200.

[0192] Understandably, the connection between the mounting base 100 and the rotary nozzle 200 via the bearing 500 helps ensure that the rotary nozzle 200 can rotate smoothly relative to the mounting base 100.

[0193] According to one embodiment of the present invention, the damping component 700 includes two annular friction plates, one of which is connected to the rotary nozzle 200 and the other is connected to the mounting base 100. It is understood that the two annular friction plates are respectively connected to the rotary nozzle 200 and the mounting base 100. When the rotary nozzle 200 rotates relative to the mounting base 100, friction is generated between the two friction plates, thereby providing a stable damping effect.

[0194] When the two annular friction plates are at the critical distance (the distance between the two annular friction plates that prevents them from contacting when the distance between them increases further), the resistance to the rotation of the rotary nozzle 200 is relatively small. As the two annular friction plates gradually approach each other, the frictional force between them also increases with the increase of pressure.

[0195] According to a second aspect of the present invention, a hair dryer is provided, including the rotating nozzle 200 assembly of the hair dryer of any of the above embodiments.

[0196] In one embodiment, the hair dryer includes a body, and a nozzle assembly is detachably mounted to the air outlet of the body. Specifically, the nozzle assembly can be detachably connected to the body via magnetic attraction. Of course, the nozzle assembly can also be detachably connected to the body via other methods such as snap-fit ​​connection or screw connection, and this invention does not specifically limit this method.

[0197] In one embodiment, at least one of the body and the base is provided with a magnetic attraction component 300, and the other is provided with a metal part or another magnetic attraction component 300. When the base is installed on the body, the magnetic attraction force can firmly connect the magnetic attraction component 300 and the metal part or another magnetic attraction component 300 together.

[0198] In one embodiment, the nozzle assembly further includes a bottom cover 400 for mounting the magnetic component 300 of the nozzle assembly to the bottom of the base.

[0199] It is understood that if the nozzle assembly of the hair dryer has the beneficial effects of the above embodiments, then the hair dryer will have the beneficial effects of the above embodiments accordingly. The specific implementation method can be referred to the above embodiments, and this application will not repeat it.

[0200] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the protection scope of the present invention.
