[0055] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model.

[0056] In the description of the embodiments of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, wherein the fixed connection can include an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0057] In the embodiments of the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

The first feature being "below", "below" and "below" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model embodiment. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0059] According to the nozzle assembly of the present invention, please refer to Figures 1 to 5 , including a mounting base 100 and a rotating air nozzle 200, the rotating air nozzle 200 is rotatably connected to the mounting base 100, the air outlet 201 of the rotating air nozzle 200 is provided with a grille component 230, the grille component 230 includes a first grille portion 231, and the first grille portion 231 is suitable for driving the rotating air nozzle 200 to rotate relative to the mounting base 100 under the push of airflow.

[0060] According to the nozzle assembly of the embodiment of the utility model, the rotating nozzle 200 can rotate relative to the mounting base 100 during use, which effectively expands the blowing area of ​​the hair dryer and can cover a wider area. Due to the increase in the blowing area, the user can dry the hair faster during use, saving time and improving hair drying efficiency.

[0061] It is understandable that the mounting base 100 is used to mount and support the rotating air nozzle 200 , and the rotating air nozzle 200 can be mounted in the mounting base 100 via a bearing 500 or other rotating connection methods, so that the rotating air nozzle 200 can rotate relative to the mounting base 100 .

[0062] It should be noted that the present invention does not impose any specific restrictions on the structure of the mounting base 100, and the rotating nozzle 200 can be arranged above the mounting base 100 or inside the mounting base 100. The rotating connection between the rotating nozzle 200 and the mounting base 100 realizes multi-angle adjustment of the nozzle assembly, so that the blowing direction of the hair dryer can be flexibly adjusted according to user needs, which increases the convenience of use.

[0063] It is understandable that the grille component 230 can guide and disperse the airflow blown out from the air outlet 201, and use the dynamic characteristics of the airflow to realize the automatic rotation of the rotating nozzle 200. When the airflow passes through the first grille part 231, the first grille part 231 can generate sufficient rotation torque to drive the rotating nozzle 200 to rotate.

[0064] It is understandable that the grille plates of the first grille portion 231 are specially designed to generate sufficient torque when air flows through, so as to drive the rotating air nozzle 200 to rotate. In this embodiment, the grille plates of the first grille portion 231 are all arranged clockwise and tilted at the air outlet 201 of the rotating air nozzle 200. Of course, the grille plates of the first grille portion 231 can also be arranged counterclockwise and tilted at the air outlet 201 of the rotating air nozzle 200. The grille plates of the first grille portion 231 are all arranged tilted in the same direction to help form a rotation torque in the same direction, thereby generating a rotation driving force.

[0065] The utility model does not limit the number of grid plates of the first grid portion 231 , and the number of the first grid plates 231 may be one or more.

[0066] It is understandable that the grille component 230 may be provided with only the first grille portion 231, and the overall structure of the grille component 230 is simpler, which reduces the manufacturing difficulty and also makes the assembly and maintenance process simpler. Of course, the grille component 230 may also be provided with a grille area with other functions, such as the second grille portion 232 mentioned later. When the grille component 230 may be provided with only the first grille portion 231, the first grille portion 231 may be spread over the air outlet 201 of the rotating air nozzle 200. When the grille component 230 is provided with a grille area with other functions, the number of the first grille portions 231 may be one or more. When the number of the first grille portions 231 is more than one, the first grille portions 231 and the first grille portions 231 may be adjacently arranged at the air outlet 201, or the first grille portions 231 and the first grille portions 231 may be arranged relative to the air outlet 201.

[0067] According to an embodiment of the present invention, please refer to Figures 5 to 7, when there are multiple first grille parts 231: multiple first grille parts 231 are symmetrically distributed along the center of the rotation axis of the rotating air nozzle 200. It can be understood that the first grille parts 231 symmetrically distributed along the center of the rotation axis of the rotating air nozzle 200 can ensure that the airflow is balanced when passing through the grille part 230. This balanced airflow distribution helps to reduce the turbulence of the airflow, making the rotating air nozzle 200 more stable when rotating. Due to the balanced airflow, the wind force of the hair dryer can be more evenly distributed in all directions, which helps to improve the blowing effect. In addition, the first grille parts 231 distributed symmetrically can more effectively utilize the power of the airflow and generate a larger rotational torque, thereby driving the rotating air nozzle 200 to rotate with higher efficiency. In addition, the central symmetrical design is more visually beautiful and coordinated, making the air nozzle assembly more attractive in appearance.

[0068] In this embodiment, the number of the first grille portions 231 is two, and the corresponding two first grille portions 231 are symmetrically disposed at two ends of the grille component 230 .

[0069] When there are multiple first grille parts 231, the distribution of the first grille parts 231 can be diversified, for example, quadrilateral distribution, arrangement on two opposite sides, or arrangement on two adjacent sides. Of course, when there are multiple first grille parts 231, the multiple first grille parts 231 can also be arranged at the air outlet 201 in other distribution modes, as long as the rotating air nozzle 200 can rotate autonomously when the airflow passes through.

[0070] According to an embodiment of the present invention, please refer to Figures 5 to 7 The grille component 230 further includes a second grille portion 232 , the first grille portion 231 is disposed on the outer side of the second grille portion 232 , and the grille plates in the first grille portion 231 and the second grille portion 232 extend in an angled direction.

[0071] It is understandable that by providing the first grille portion 231 and the second grille portion 232, and by setting the grille plate extension direction at an angle, multi-level airflow control can be achieved. The first grille portion 231 is mainly responsible for driving the rotating air nozzle 200 to rotate under the impetus of the airflow, while the second grille portion 232 can be used to further optimize the airflow distribution, reduce noise or provide a specific blowing effect (for example, the second grille portion 232 mentioned later stores hair care products). This multi-level design makes the airflow control more flexible, thereby meeting the use needs of different users.

[0072] It can be understood that since the first grille portion 231 is disposed on the outer side of the second grille portion 232, it helps to better utilize the dynamic characteristics of the airflow, so that the rotating air nozzle 200 can obtain a larger rotational torque and thus rotate more smoothly.

[0073] In one embodiment, please refer to Figure 5 The extension directions of the grid plates of the first grid portion 231 and the grid plates of the second grid portion 232 are perpendicular to each other.

[0074] Of course, the angle between the extension directions of the grid plates of the first grid portion 231 and the second grid portion 232 may also be other values, such as 30°, 60°, and 90°.

[0075] According to an embodiment of the present invention, please refer to Figure 5 , when the number of the first grille parts 231 is two: the second grille part 232 is disposed between the two first grille parts 231 .

[0076] It can be understood that the first grille portion 231 serving as a driver is arranged on both sides of the second grille portion 232, which can better enable the rotating air nozzle 200 to obtain a larger rotational torque, and can effectively balance and optimize the airflow distribution blown out from the hair dryer outlet 201. The second grille portion 232 can further disperse and guide the airflow to avoid the situation where the airflow is too concentrated or sparse in certain areas.

[0077] Since the second grille portion 232 is located between the two first grille portions 231, it can act as a bridge to connect the two first grille portions 231, which helps to reduce the shaking and instability of the rotating air nozzle 200 during the rotation process and improve the smoothness and stability of the rotation.

[0078] According to an embodiment of the utility model, the inclination angle of the grille plate of the first grille portion 231 is adjustable. It is understandable that by adjusting the inclination angle of the grille plate of the first grille portion 231, the user can adjust the rotation speed of the rotating air nozzle 200. For example, when the inclination angle of the grille plate of the first grille portion 231 is small (excluding the case where the inclination angle is 0), the driving force received by the rotating air nozzle 200 is large, and the rotation speed of the rotating air nozzle 200 is fast. When the inclination angle of the grille plate is large, the driving force received by the rotating air nozzle 200 is small, and the rotation speed of the rotating air nozzle 200 is slow.

[0079] It should be noted that the inclination angle here can be understood as the angle between the grille plate and the plane where the air outlet 201 is located. In one embodiment, the grille plate of the first grille portion 231 is tangent to the air guide channel, in other words, the inclination angle of the grille plate of the first grille portion 231 is 0, and the rotating air nozzle 200 does not rotate.

[0080] In one embodiment, the angle between the grille plate of the first grille portion 231 and the air outlet 201 is 90°, and the rotating air nozzle 200 can discharge air smoothly without causing the rotating air nozzle 200 to rotate.

[0081] It should be noted that the grille plate of the first grille portion 231 not only has the function of driving the rotating air nozzle 200 to rotate, but also has the function of discharging air. The adjustability of the grille plate's inclination angle enables the user to easily adjust the wind speed and rotation effect during the blowing process. There is no need to replace the air nozzle or adjust other complex settings. The user only needs to simply adjust the inclination angle of the grille plate to achieve the desired effect. This convenience not only improves the user experience, but also reduces the complexity of operation.

[0082] According to one embodiment of the utility model, the inclination angle of the grille plate of the second grille portion 232 is adjustable. It is understandable that the user can adjust the angle of the grille plate according to actual needs, thereby changing the direction and distribution of the airflow. Whether it is necessary to concentrate the wind force for local styling, or to blow air evenly to dry the hair quickly, it can be achieved by adjusting the angle of the grille plate. This design makes the hair dryer more flexible and practical, and can adapt to the blowing needs of different users. For example, when the inclination angle of the grille plate of the second grille portion 232 is small, the airflow is more concentrated, which is suitable for local styling or strong wind drying; and when the angle of the grille plate is large, the airflow is more dispersed, which is suitable for uniform blowing or gentle care. This adjustability allows users to choose the best blowing effect according to their hair quality, hairstyle and blowing purpose.

[0083] According to an embodiment of the present invention, please refer to Figures 8 to 10 The first grille portion 231 includes a plurality of grille plates, any of which includes a first arc structure 233 and a second arc structure 234. The first arc structure 233 and the second arc structure 234 are respectively arranged on both sides of the rotating shaft of the rotating air nozzle 200, and the first arc structure 233 and the second arc structure face opposite directions, and the first arc structure 233 and the second arc structure 234 are smoothly transitioned and connected. When the airflow acts on the first arc structure 233 and the second arc structure 234, since the chord tangent angles of the first arc structure 233 and the second arc structure 234 of the plurality of grille plates are different, the airflow and the grille can form a driving force in the counterclockwise direction or the clockwise direction, thereby driving the grille to rotate.

[0084] It should be noted that the first arc structure 233 and the second arc structure 234 are respectively disposed on both sides of the rotating shaft of the rotating air nozzle 200. Figure 8 The rotating shaft is at a cross-shaped position in the figure, and the first arc structure 233 and the second arc structure 234 are respectively arranged on opposite sides of the rotating shaft.

[0085] It should be noted that the first arc structure 233 and the second arc structure 234 are oriented in opposite directions, that is, the opening of the first arc structure 233 and the opening of the second arc structure 234 are oriented oppositely. For example, when the first arc structure 233 opens downward, the second arc structure 234 opens upward; when the first arc structure 233 opens to the left, the second arc structure 234 opens to the right, and so on.

[0086] In one embodiment, the first arc structure 233 and the second arc structure 234 have the same curvature. It is understood that the same curvature makes the air flow characteristics generated by the grille plate in the first arc structure 233 and the second arc structure 234 during rotation consistent, ensuring stable rotation.

[0087] Of course, the curvature of the first arc structure 233 and the second arc structure 234 may also be different. Different air flow effects can be produced through differentiated designs, thereby controlling the air outlet effect of the rotating air nozzle 200. The specific curvature can be designed according to actual conditions to meet the ventilation needs of a specific area.

[0088] In one embodiment, the first arc structure 233 and the second arc structure 234 are symmetrical with respect to the center of the rotating shaft of the rotating air nozzle 200. It can be understood that since the first arc structure 233 and the second arc structure 234 are symmetrical with respect to the center of the rotating shaft of the rotating air nozzle 200, the air flow will be more evenly distributed on both sides, reducing the asymmetric pressure generated during the air flow.

[0089] Of course, the first arc structure 233 and the second arc structure 234 can also be asymmetrically arranged on both sides of the rotating shaft of the rotating nozzle 200. The asymmetrical arrangement can generate airflows of different directions and speeds. Similarly, through differentiated designs, different air flow effects can be generated, thereby controlling the air outlet effect of the rotating nozzle 200.

[0090] In one embodiment, the curvature of the first curved structures 233 or the second curved structures 234 of any two adjacent grille plates may be the same. The first curved structures 233 or the second curved structures 234 with the same curvature produce similar air outlet effects, making the air flow more consistent.

[0091] Of course, the curvatures of the first arc structures 233 or the second arc structures 234 of any two adjacent grid plates may also be different, and no specific limitation is made here.

[0092] In one embodiment, the included angles of the arc chord section of the first arc structure 233 or the second arc structure 234 of any two adjacent grille plates are the same as the cross section of the air outlet 201. It can be understood that it can ensure that the air flows at a similar angle when passing through two adjacent grille plates, so that the wind direction is unified and the user experience is improved.

[0093] Of course, the angles between the curved chord sections of the first curved structure 233 or the second curved structure 234 of any two adjacent grille plates and the cross section of the air outlet 201 may also be different. By flexibly setting the angles, the influence of the ventilation system on the air quality can be more effectively controlled. For example, the angle between the curved chord section of the grille plate close to the rotation center and the cross section of the air outlet 201 is larger, so that the wind close to the rotation center can flow outward at a larger angle, and the angle between the curved chord section of the grille plate far from the rotation center and the cross section of the air outlet 201 is smaller, so that the wind far from the rotation center can cover other corners.

[0094] In one embodiment, please refer to Figures 8 to 10 , the grille angle of any two adjacent grille plates close to the center of the air outlet 201 is greater than the grille angle of any two adjacent grille plates far from the center of the air outlet 201. The grille angle is the angle between the arc chord section of the first arc structure 233 or the second arc structure 234 and the cross section of the air outlet 201. That is, the angle between the arc chord section of the first arc structure 233 or the second arc 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 to both ends.

[0095] Please note that, please refer to Fig. 9 , the angle between the second arc structure 234 (DD section view in the figure is the section view of the second arc structure 234) near 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 structure 234 away from the center of the air outlet 201 and the cross section of the air outlet 201 gradually decreases. Of course, the angle between the arc chord section of the first arc structure 233 corresponding to the second arc structure 234 and the cross section of the air outlet 201 also decreases from the center of the air outlet 201 to both ends.

[0096] According to one embodiment of the utility model, the mounting seat 100 and the rotating air nozzle 200 are connected via a bearing 500, one of the mounting seat 100 and the rotating air nozzle 200 is provided with a mounting hole, the outer ring of the bearing 500 is installed in the mounting hole, and the inner ring of the bearing 500 is connected to the other of the mounting seat 100 and the rotating air nozzle 200.

[0097] It is understandable that the connection between the mounting base 100 and the rotating air nozzle 200 via the bearing 500 helps to ensure that the rotating air nozzle 200 can smoothly rotate relative to the mounting base 100 .

[0098] According to one embodiment of the utility model, a magnetic component 300 is also included, and the magnetic component 300 is arranged on the side of the mounting base 100 facing away from the air outlet 201. It can be understood that the magnetic component 300 makes the connection between the mounting base 100 and other related components or surfaces more convenient. By utilizing the principle of magnetic adsorption, the mounting base 100 can be easily fixed without using traditional fixing methods such as screws and buckles. Similarly, disassembly becomes simple and fast, and separation can be achieved by simply overcoming the magnetic force, which greatly improves the convenience of operation.

[0099] According to an embodiment of the utility model, a storage component is further included, and the storage component is arranged corresponding to the grille component 230, and the storage component is used to store hair care products. It is understandable that when using a hair dryer for hair styling, users often need to use hair care products, such as styling spray, hair care essential oil, etc. By arranging the storage component on the grille component 230, users can conveniently use these hair care products during the hair drying process, thereby greatly improving the convenience of use.

[0100] According to an embodiment of the present invention, the mounting base 100 includes a base 110 and a housing 120, the base 110 is connected to the housing 120, a mounting cavity 101 is formed between the base 110 and the housing 120, and the rotating air nozzle 200 is at least partially disposed in the mounting cavity 101. It can be understood that the mounting base 100 composed of the base 110 and the housing 120 provides a stable installation environment for the rotating air nozzle 200, and at the same time, the mounting cavity 101 also provides a certain degree of protection for the rotating air nozzle 200, preventing external factors (such as dust, moisture, etc.) from directly contacting the rotating air nozzle 200, thereby extending its service life.

[0101] In one embodiment, the rotating nozzle 200 is partially located in the installation cavity 101, and the air outlet 201 of the rotating nozzle 200 extends out of the installation cavity 101. Since the air outlet 201 extends out of the installation cavity 101, the air outlet 201 is not restricted by the installation cavity 101, so that the blowing area of ​​the air outlet 201 can be larger.

[0102] Of course, the rotating air nozzle 200 may also be completely located in the installation cavity 101. The installation cavity 101 can provide protection for the rotating air nozzle 200 and prevent the user from accidentally touching the rotating air nozzle.

[0103] In one embodiment, a cap screw 600 is further included, and the cap screw 600 is used to fix the bearing 500 to the mounting seat 100 .

[0104] According to the nozzle assembly of the present invention, please refer to Figure 2 , Figure 11 to Figure 12The air nozzle assembly includes a housing 120, a mounting seat 100, a rotating air nozzle 200, a first damping component 710 and a first adjusting component 720. The housing 120 is provided with a mounting cavity 101; the mounting seat 100 is at least partially disposed in the mounting cavity 101; the rotating air nozzle 200 is disposed in the mounting cavity 101 and is rotatably connected to the mounting seat 100; the first damping component 710 is disposed between the housing 120 and the rotating air nozzle 200; and the first adjusting component 720 is connected to the first damping component 710 and is used to adjust the rotation resistance of the first damping component 710.

[0105] According to the nozzle assembly of the embodiment of the utility model, the rotating nozzle 200 can 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, the user can dry the hair faster during use, saving time and improving the hair drying efficiency. The first damping component 710 provides rotational resistance between the rotating nozzle 200 and the housing 120. Through the adjustment of the first adjustment component 720, the rotational resistance of the first damping component 710 can be adjusted, thereby controlling the rotation speed of the rotating nozzle 200. On the basis of being able to obtain a larger blowing area, the rotation speed requirements of different users can also be met.

[0106] It should be noted that the rotation resistance may be friction, electromagnetic resistance, etc.

[0107] It is understandable that the mounting base 100 is used to mount and support the rotating nozzle 200, and the rotating nozzle 200 can be mounted in the mounting base 100 by means of a bearing 500 or other rotating connection, so that the rotating nozzle 200 can rotate relative to the mounting base 100. Through the rotating connection between the rotating nozzle 200 and the mounting base 100, the multi-angle adjustment of the nozzle assembly is realized, so that the blowing direction of the hair dryer can be flexibly adjusted according to user needs, which increases the convenience of use.

[0108] It is understandable that the first damping component 710 mainly serves to provide 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 adjusting the friction between the first damping component 710 and the housing 120, so that the user can adjust the blowing effect according to their needs.

[0109] It should be noted that the first damping component 710 can be a common shock absorber, spring damper, friction plate, etc. on the market, as long as it can provide sufficient friction, and the present invention does not impose specific restrictions on this. The first adjusting component 720 can be a common lifting screw rod, telescopic rod, elastic member, etc. on the market, as long as it can change the length direction, and the present invention does not impose specific restrictions on this. Any combination of the first damping component 710 and the first adjusting component 720 is within the protection scope of the present invention.

[0110] Of course, the first damping component 710 can also be an electromagnet commonly available on the market that can change the magnetic resistance. This is a prior art and will not be described in detail in this application.

[0111] It should be noted that the rotational power of the rotating air nozzle 200 can be generated when the airflow passes through (an embodiment of generating power is introduced later), or it can be generated by a motor drive. The present utility model does not impose specific restrictions on the rotational power of the rotating air nozzle 200.

[0112] In one embodiment, the first end of the first damping component 710 is connected to one of the housing 120 and the rotating air nozzle 200, the second end of the first damping component 710 abuts against the other, and the extrusion force of the second end of the first damping component 710 is adjustable. When the extrusion force at the second end of the first damping component 710 increases, the friction force provided by the first damping component 710 increases, and when the extrusion force at the second end of the first damping component 710 decreases, the friction force provided by the first damping component 710 decreases.

[0113] According to an embodiment of the present invention, there are multiple first damping components 710 , which are arranged at intervals on the outer circumference of the rotating air nozzle 200 .

[0114] It is understandable that by arranging the plurality of first damping components 710 at intervals, a plurality of friction points can be formed on the periphery of the rotating air nozzle 200, thereby increasing the damping effect. The damping components arranged at intervals can be flexibly adjusted according to the use 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 intervals can be adjusted.

[0115] According to an embodiment of the present invention, there is one first damping component 710 , which is disposed around the outer circumference of the rotating air nozzle 200 .

[0116] It is understandable that a single damping component is arranged around the outer periphery of the rotating air nozzle 200, making the structure of the entire air nozzle assembly more concise, reducing the number of parts and assembly steps, reducing production costs, and also helping to improve product reliability and stability. The damping component arranged around the outer periphery of the rotating air nozzle 200 can form a continuous friction surface, provide uniform damping force, and make the rotating air nozzle 200 more evenly stressed when rotating.

[0117] According to an embodiment of the present invention, please refer to Fig.11 and Fig.12 The first adjustment component 720 is provided with an adjustment rail 721. When the first adjustment component 720 is installed to one of the housing 120 and the rotating air nozzle 200, the extension direction of the adjustment rail 721 is toward the other of the housing 120 and the rotating air nozzle 200, and the first end of the first damping component 710 is connected to the adjustment rail 721.

[0118] It is understandable that the damping effect can be adjusted by adjusting the position of the damping component on the adjustment track 721 to adjust the distance between the first matching portion 210 and the second matching portion 130 .

[0119] It should be noted that the extension direction of the adjustment track 721 is toward the housing 120 or the rotating air nozzle 200 , and the direction here can be vertical or at an angle. For example, the adjustment track 721 can form an angle of 45° with the tangent of the rotating air nozzle 200 .

[0120] According to an embodiment of the present invention, please refer to Figures 1 to 5 The rotating air nozzle 200 is provided with a first matching portion 210, and the mounting seat 100 includes a seat body 140 and a second matching portion 130, the seat body 140 is connected to the second matching portion 130, the second matching portion 130 is arranged at the center of the seat body 140, and the first matching portion 210 is passed through the assembly hole 131 of the second matching portion 130.

[0121] It is understandable that by arranging the second matching portion 130 at the center of the seat body 140, the structure of the entire mounting seat 100 is made more compact. The first matching portion 210 is inserted into the assembly hole 131 of the second matching portion 130. This insertion design not only simplifies the assembly process, but also enhances the connection stability between the rotating air nozzle 200 and the mounting seat 100.

[0122] According to an embodiment of the present invention, please refer to Figures 1 to 5 , and also includes a cap screw. The first matching portion 210 is provided with a threaded hole, the threaded hole opening is facing away from the air outlet 201 of the rotating air nozzle 200, and the cap screw is arranged in the threaded hole so that the end face of the threaded hole opening is flush with the end face of the second matching portion 130.

[0123] It is understandable that the cap screw is tightly matched with the threaded hole of the first matching portion 210 through the thread, forming a strong connection mode. This connection mode not only enhances the connection strength between the rotating air nozzle 200 and the mounting seat 100, but also improves the structural stability of the entire air nozzle assembly.

[0124] According to an embodiment of the present invention, please refer to Figures 1 to 5 The outer periphery of the seat body 140 is provided with a buckle interface 141, and the shell 120 is provided with a buckle portion 121, and the buckle portion 121 is buckled with the buckle interface 141. It can be understood that through the buckle design of the buckle interface 141 and the shell 120, the assembly between the mounting seat 100 and the shell 120 becomes very simple and quick. The user only needs to align the buckle portion 121 of the shell 120 with the buckle interface 141 and gently buckle it to complete the assembly process. This design not only reduces the difficulty of assembly, but also improves the efficiency of assembly.

[0125] According to an embodiment of the present invention, please refer to Figures 1 to 5 , and further includes a bottom cover 400, which is detachably mounted on the mounting base 100. The detachable design of the bottom cover 400 also makes it easier to replace or upgrade the components inside the mounting base 100. For example, the magnetic component 300 mentioned later, the user can easily replace the magnetic component 300 by removing the bottom cover 400 without disassembling the entire nozzle assembly.

[0126] According to an embodiment of the present invention, please refer to Figure 2 and Fig.13 , also includes a second damping component 810 and a second adjusting component 820, the second damping component 810 is arranged between the mounting seat 100 and the rotating air nozzle 200, the second adjusting component 820 is connected to the second damping component 810, and the second adjusting component 820 is used to adjust the rotational resistance of the second damping component 810.

[0127] It is understandable that the second damping component 810 mainly serves to provide rotational resistance between the rotating nozzle 200 and the mounting base 100. The second adjusting component 820 changes the distance between the mounting base 100 and the rotating nozzle 200, thereby changing the rotational resistance of the second damping component 810 and controlling the rotation speed of the rotating nozzle 200. Users can adjust the blowing effect according to their needs.

[0128] It should be noted that the second damping component 810 can be a common shock absorber, spring damper, friction plate, etc. on the market, as long as it can provide sufficient friction, and the present invention does not impose specific restrictions on this. The second adjusting component 820 can be a common lifting screw rod, telescopic rod, elastic member, etc. on the market, as long as it can change the length direction, and the present invention does not impose specific restrictions on this. Any combination of the second damping component 810 and the second adjusting component 820 is within the protection scope of the present invention.

[0129] Of course, the second damping component 810 can also be an electromagnet commonly available on the market that can change the magnetic resistance. This is a prior art and will not be described in detail in this application.

[0130] It should be noted that the rotational power of the rotating air nozzle 200 can be generated when the airflow passes through (an embodiment of generating power is introduced later), or it can be generated by a motor drive. The present utility model does not impose specific restrictions on the rotational power of the rotating air nozzle 200.

[0131] It can be understood that as the rotational resistance provided by the second damping component 810 increases, the rotational speed of the rotating air nozzle 200 decreases; as the rotational resistance provided by the second damping component 810 decreases, the rotational speed of the rotating air nozzle 200 increases; when the rotational resistance provided by the second damping component 810 is large enough, the rotating air nozzle 200 no longer rotates, and the rotating air nozzle 200 can be regarded as being fixed to the mounting seat 100. The air nozzle assembly of the utility model is described below in conjunction with an embodiment:

[0132] When the user uses a hair dryer with the nozzle assembly, the rotating nozzle 200 can rotate relative to the mounting base 100 to increase the blowing area. When the user thinks that the blowing area of ​​the rotating nozzle 200 is too large, the second adjusting 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 rotation resistance of the second damping component 810 can be adjusted to the maximum, and the rotating nozzle 200 will no longer rotate.

[0133] According to one embodiment of the utility model, the rotating air nozzle 200 is provided with a first matching portion 210, the mounting base 100 includes a base body 140 and a second matching portion 130 connected to each other, the second matching portion 130 is arranged at the center of the base body 140, and the second damping component 810 is arranged between the first matching portion 210 and the second matching portion 130.

[0134] It is understandable that by placing the second damping component 810 between the first matching portion 210 and the second matching portion 130, the contact area between the second damping component 810 and the rotating air nozzle 200 and the mounting base 100 is increased, which can ensure that the second damping component 810 plays the greatest role when the rotating air nozzle 200 rotates. The second adjustment component 820 can effectively adjust the friction of the second damping component 810 by changing the distance between the first matching portion 210 and the second matching portion 130.

[0135] According to an embodiment of the present invention, please refer to Figure 2 and Fig.13 The second adjusting component 820 includes a threaded knob, a threaded hole is provided at the center of the second matching portion 130, the threaded knob passes through the first matching portion 210 and is connected to the threaded hole, and is suitable for adjusting the distance between the first matching portion 210 and the second matching portion 130.

[0136] It is understandable that by rotating the threaded knob, the spacing between the first mating portion 210 and the second mating portion 130 can be precisely adjusted, thereby achieving fine adjustment of the friction force of the second damping component 810. The threaded connection method makes the adjustment process stable and reliable, and is not prone to slippage or loosening, thereby ensuring the durability of the adjustment effect.

[0137] In this embodiment, the head of the threaded knob that can be rotated by the user is set 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 matching part 130. The user can adjust the first matching part 210 and the second matching part 130 by means of parts. This operation method is intuitive, easy to understand and simple to operate.

[0138] Of course, the head of the threaded knob that can be rotated by the user can also be set at other positions of the nozzle assembly.

[0139] According to an embodiment of the present invention, please refer to Figure 6 The second adjusting component 820 also includes an elastic member, one end of which is connected to the second damping component 810 , and the other end of the elastic member is connected to the second matching portion 130 .

[0140] It can be understood that the elastic member can provide pressure to the second damping component 810, so that the second damping component 810 can form a more effective resistance.

[0141] According to an embodiment of the present invention, please refer to Figure 4The base is provided with a guide portion 132 and an air inlet 142, and the air inlet 142 is arranged on the outer periphery of the guide portion 132. An air guide flow section 143 is formed between the outer contour of the guide portion 132 and the rotating air nozzle 200, and the air guide flow section 143 connects the air outlet 201 and the air inlet 142.

[0142] It can be understood that the air inlet 142 is located at the periphery of the guide portion 132, and the guide portion 132 can form a guide effect, guiding the air to flow along the path of the guide flow section 143, so that the air can flow out from the air outlet 201 according to a specific flow direction and speed, which helps to increase the airflow to push the first grille portion 231 and drive the rotating air nozzle 200 to rotate relative to the base.

[0143] According to an embodiment of the present invention, please refer to Figure 4 , along the direction from the air inlet 142 to the air outlet 201 , the outer contour of the guide portion 132 gradually decreases.

[0144] It can be understood that the airflow flows along the outer contour of the guide portion 132 to the air outlet 201. As the outer contour of the guide portion 132 gradually decreases, the air guide channel becomes wider and the gas outlet area is larger, making the user feel more comfortable when using the hair dryer.

[0145] It should be noted that the cross section of the guide portion 132 may be circular or in other curved shapes, and no specific limitation is imposed herein.

[0146] According to an embodiment of the present invention, along the direction from the air inlet 142 to the air outlet 201 , the outer contour of the air guide portion 132 increases first and then decreases.

[0147] It is understandable that the airflow flows along the outer contour of the guide portion 132 to the air outlet 201. As the outer contour of the guide portion 132 increases, the air guide channel becomes narrower and the gas flow rate increases. As the outer contour of the guide portion 132 decreases, the air guide channel becomes wider, the gas outlet area becomes larger, and the gas undergoes a process of first compression and then release during the flow process, thereby generating a larger air volume and wind pressure at the air outlet 201. Such a setting can also reduce the turbulence and eddy currents generated during the air flow process to a certain extent, thereby reducing the generation of noise.

[0148] According to an embodiment of the present invention, please refer to Figure 2 or Fig.10 The base is provided with a plurality of air guide blades, which are spaced apart on the base body 140 and are used to separate the air flow passing through the guide portion 132 and guide the air flow to the rotating air nozzle 200 .

[0149] It can be understood that the air guide blades 170 on the mounting base 100 can effectively separate the air flow passing through the mounting base 100 and guide it to the rotating air nozzle 200. Through the guidance of the blades, the air flow can pass through the mounting base 100 more smoothly, reducing resistance loss, thereby enhancing the blowing effect.

[0150] According to an embodiment of the present invention, please refer to Fig.10 The air guide blades 170 are disposed correspondingly to the grille plates of the first grille portion 231. By disposing the air guide blades 170 correspondingly to the grille plates of the first grille portion 231, the airflow can be effectively separated and guided to the rotating air nozzle 200.

[0151] It should be noted that the air guide blade 170 and the grille plate of the first grille portion 231 are arranged correspondingly, including position correspondence, and / or shape correspondence. Among them, the position correspondence can be understood as the position correspondence between the air guide blade 170 and the grille plate of the first grille portion 231. For example, the air guide blade 170 is arranged directly below the grille plate of the first grille portion 231. Of course, the air guide blade 170 is not limited to being arranged directly below the grille plate of the first grille portion 231, and can also be arranged at other positions, as long as the position relationship between the air guide blade 170 and the grille plate is arranged one-to-one. Among them, the shape correspondence can be understood as the inclination angle of the first grille plate air guide blade 170 is the same as the inclination angle of the first grille plate, and / or the curvature of the air guide blade 170 is the same as the curvature of the first grille plate, so that the air guide direction and air guide effect of the air guide blade 170 and the first grille plate correspond to each other, thereby reducing wind loss.

[0152] According to an embodiment of the present invention, please refer to Figure 2 The mounting seat 100 further includes a plurality of baffle blades 150 . The second matching portion 130 is provided with a guide portion 132 . The baffle blades 150 are arranged in the circumference of the guide portion 132 to connect the guide portion 132 and the seat body 140 .

[0153] It is understandable that the air guide 132 can effectively separate and guide the airflow passing through the mounting seat 100 to the rotating air nozzle 200. The partition blade 150 is used to connect the central air guide 132 and the circumferential seat body 141 for mechanical support and to improve the stability of the mounting seat. The connection between the partition blade 150 and the seat body 140 can strengthen the overall structure of the seat body 140, improve its deformation resistance and impact resistance, and help ensure that the mounting seat 100 can maintain stable performance during long-term use and extend its service life.

[0154] According to an embodiment of the present invention, please refer to Figure 2 and Figure 8One of the second matching part 130 and the rotating air nozzle 200 is provided with a mounting hole 160, and the mounting hole 160 is provided with a bearing 500. The outer ring of the bearing 500 is installed in the mounting hole 160, and the inner ring of the bearing 500 is connected to the other of the second matching part 130 and the rotating air nozzle 200.

[0155] It is understandable that the connection between the mounting base 100 and the rotating air nozzle 200 via the bearing 500 helps to ensure that the rotating air nozzle 200 can smoothly rotate relative to the mounting base 100 .

[0156] According to an embodiment of the present invention, the damping component 700 includes two annular friction plates, one of which is connected to the rotating air nozzle 200, and the other is connected to the mounting seat 100. It can be understood that the two annular friction plates are respectively connected to the rotating air nozzle 200 and the mounting seat 100, and when the rotating air nozzle 200 rotates relative to the mounting seat 100, friction will be generated between the two friction plates, thereby providing a stable damping effect.

[0157] When the two annular friction plates are at a critical distance, which is the distance between the two annular friction plates when the distance between them increases, the resistance to the rotation of the rotating air nozzle 200 is small. When the two annular friction plates gradually approach each other, the friction between the two friction plates increases as the pressure increases.

[0158] The hair dryer according to the second embodiment of the utility model comprises the above-mentioned nozzle assembly. It is understandable that the hair dryer has all the technical effects of the above-mentioned nozzle assembly because it comprises the above-mentioned nozzle assembly, which will not be described in detail here.

[0159] In one embodiment, the hair dryer includes a body, and the nozzle assembly is detachably mounted at the air outlet position of the body. Specifically, the nozzle assembly can be detachably connected to the body by magnetic attraction. Of course, the nozzle assembly can also be detachably connected to the body by other methods such as snap connection, screw connection, etc., and the utility model does not specifically limit this.

[0160] In one embodiment, at least one of the body and the mounting base 100 is provided with a magnetic component 300, and the other is provided with a metal part or another magnetic component 300. When the mounting base 100 is installed to the body, the magnetic force can firmly connect the magnetic component 300 and the metal part or another magnetic component 300 together.

[0161] In one embodiment, the nozzle assembly further includes a bottom cover 400 , and the bottom cover 400 is used to install the magnetic attraction component 300 of the nozzle assembly on the bottom of the mounting base 100 .

[0162] Finally, it should be noted that the above implementation modes are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, a person skilled in the art should understand that various combinations, modifications or equivalent replacements 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 included in the scope of the claims of the present invention.
