[0036] 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.

[0037] According to the nozzle assembly of the hair dryer of the present utility model, please refer to Figures 1 to 4The air nozzle assembly includes a mounting base 110 and a rotating air nozzle 200. The rotating air nozzle 200 is rotatably connected to the mounting base 110. The air outlet 201 of the rotating air nozzle 200 is eccentrically arranged relative to the mounting base 110. When the rotating air nozzle 200 rotates, the air outlet 201 of the rotating air nozzle 200 is suitable for rotating around the central axis 101 of the mounting base.

[0038] According to the nozzle assembly of the embodiment of the utility model, the air outlet 201 of the rotating nozzle 200 can rotate around the central axis 101 of the mounting base relative to the mounting base 110 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.

[0039] It is understandable that the mounting seat 110 is used to mount and support the rotating air nozzle 200, and the rotating air nozzle 200 can be mounted in the mounting seat 110 through a bearing 500 or other rotating connection methods. It should be noted that the present invention does not impose specific restrictions on the structure of the mounting seat 110, and the rotating air nozzle 200 can be arranged outside the mounting seat 110 or inside the mounting seat 110.

[0040] The eccentric setting of the air outlet 201 of the rotating air nozzle 200 relative to the mounting base 110 can be understood as the center point 104 of the air outlet and the center axis of the mounting base 110 do not coincide with each other, and have a certain offset, so that when the rotating air nozzle 200 rotates, the air outlet 201 can rotate around the center axis of the mounting base 110, thereby realizing flexible adjustment of the blowing area.

[0041] It should be noted that the air outlet 201 of the rotating air nozzle 200 can be a regular shape. For example, when the air outlet 201 of the rotating air nozzle 200 is circular, the center point 104 of the air outlet is the position of the center of the circle. When the air outlet 201 of the rotating air nozzle 200 is elliptical, the center point 104 of the air outlet is the center point of the ellipse. Of course, the air outlet 201 of the rotating air nozzle 200 can also be other irregular shapes. The utility model does not impose specific restrictions on the shape of the air outlet 201 of the rotating air nozzle 200. Irregular shapes also have geometric center points, which will not be repeated here.

[0042] It should be noted that the straight line passing through the center point 104 of the air outlet and perpendicular to the air outlet 201 is the central axis of the air outlet 201, and the central axis of the rotating air nozzle 200 and the central axis of the mounting base 110 may be parallel to each other, may intersect, or may not intersect. 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 described in detail here.

[0043] 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 air nozzle 200 can maintain a stable blowing effect during the rotation process. The overall direction of the airflow blown out 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. In addition, 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 air nozzle assembly can be improved, and the swing and shaking of the rotating air nozzle 200 during the rotation process can be reduced, ensuring a smoother blowing process.

[0044] For another example, when the central axis of the air outlet 201 intersects the central axis of the mounting base 110, a wider range of rotation can be achieved. Such a design allows the air outlet 201 to rotate within a larger angle range to meet the user's needs for various blowing angles. The intersection setting can achieve multi-angle blowing of the air outlet 201 in the vertical and horizontal directions. The user can adjust the blowing direction by rotating the air nozzle 200 to achieve a more precise and personalized blowing effect. The intersection setting of the central axis of the air outlet 201 and the central axis of the mounting base 110 increases the flexibility of the rotation of the air outlet 201, and the user can freely adjust the angle of the air outlet 201 as needed to meet different blowing needs and improve the convenience of use. The intersection setting can make better use of space, making the entire air nozzle assembly more compact in design, saving space, and suitable for blowing equipment of various sizes.

[0045] For another example, when the central axis of the air outlet 201 and the central axis of the mounting base 110 do not intersect, a wider rotation range can also be achieved, which will not be described in detail here.

[0046] In one embodiment, the eccentric angle of the rotating air nozzle 200 is adjustable, so that the central axis of the air outlet 201 and the central axis of the mounting base 110 are switched from parallel to intersecting or non-intersecting, or the central axis of the air outlet 201 and the central axis of the mounting base 110 are switched from intersecting or non-intersecting to parallel. Thus, the user can adjust the air outlet area of ​​the rotating air nozzle 200 according to their own needs.

[0047] In one embodiment, the eccentric distance of the rotating air nozzle 200 is adjustable, so that the distance between the central axis of the air outlet 201 and the central axis of the mounting base 110 is adjustable, and the user can adjust the air outlet area according to their own needs, thereby improving the convenience of use.

[0048] 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.

[0049] According to an embodiment of the present invention, please refer to Figures 3 to 6 The rotating air nozzle 200 includes a first matching portion 210, an air guide component 220 and a plurality of grille plates 230. The first matching portion 210 and the grille plates 230 are arranged at the air outlet 201 of the air guide component 220. The first matching portion 210 is rotatably connected to the mounting seat 110, and the air guide component 220 and the first matching portion 210 are connected through the grille plates 230.

[0050] It is understandable that the coaxial arrangement of the central axis of the first matching portion 210 and the mounting seat 110 can increase the stability of the air outlet, reduce shaking during the rotation process, and ensure a smoother blowing process. In other words, the first matching portion 210 and the mounting seat 110 are rotatably connected, and the first matching portion 210 and the center point 104 of the air outlet are eccentrically arranged.

[0051] It can be understood that an air guide channel 202 is formed inside the air guide component 220, and the air flow can pass through the air guide channel 202 and leave from the air outlet 201 of the air guide channel 202. The grille plate 230 can help guide the wind flow to flow smoothly out of the air outlet 201 of the air guide component 220, ensuring the concentration and uniformity of wind force and improving the blowing effect.

[0052] According to the embodiment of the present application, the grille plate 230 includes at least two different lengths, and the grille plates of different lengths can affect the speed and wind force distribution of the wind flow, thereby adjusting the blowing effect. The rotating air nozzle 200 can also be made to rotate autonomously by setting grille plates of different lengths.

[0053] It is understandable that when the gas passes through the grid plate 230, the driving force received by the longer grid plate 230 is greater than the driving force received by the shorter grid plate 230, forming a rotation torque, thereby causing the rotating nozzle 200 to rotate autonomously.

[0054] The different distribution densities of the grid plates 230 can also make the rotating air nozzle 200 rotate autonomously. It is understandable that the difference in grid density will affect the driving force of the gas on the grid plates 230. The grid plates 230 with higher density will receive greater gas driving force, thereby enhancing the generation of rotational torque and prompting the rotating air nozzle 200 to rotate autonomously more effectively.

[0055] According to an embodiment of the present invention, please refer to Figures 1 to 6 The air guiding component 220 includes an air inlet 203 , an air guiding channel 202 and an air outlet 201 , and the air guiding channel 202 connects the air inlet 203 and the air outlet 201 , wherein the air outlet 201 is eccentrically arranged relative to the air inlet 203 .

[0056] It is understandable that by eccentrically arranging the air outlet 201 relative to the air inlet 203, the speed and pressure of the airflow can be increased, the direction and velocity of the airflow can be changed, which helps to improve the transmission efficiency of the wind force and ensure that the airflow can effectively reach the target area. A rotational torque can also be generated to cause the air guide component 220 to rotate autonomously, thereby achieving more effective wind direction adjustment and control.

[0057] According to an embodiment of the present invention, the air guiding channel 202 is in a closed shape along the direction from the air inlet 203 of the air guiding component 220 to the air outlet 201 of the air guiding component 220 .

[0058] It is understandable that the closed-end design of the air guide channel 202 can gradually reduce the cross-sectional area of ​​the air guide channel 202 when the air flows through the channel, thereby increasing the air flow speed. This can increase the speed and pressure of the air flow and enhance the blowing effect. The closed-end design can more effectively guide the air flow, reduce energy loss, and improve the ventilation effect.

[0059] It is understandable that the closing shape may be a trumpet-shaped structure that gradually reduces the cross-sectional area of ​​the air guiding channel 202, or a stepped structure that reduces the cross-sectional area of ​​the air guiding channel 202 in a step-by-step manner, and no specific limitation is made here.

[0060] According to an embodiment of the present invention, the included angles between the cross sections of the grille plate 230 and the air outlet 201 are different, so that the airflow and the grille plate 230 act to form different forces to drive the rotating air nozzle 200 to rotate.

[0061] It is understandable that, since the cross-section of the grille plate 230 and the air outlet 201 has a certain angle, the airflow generates thrust after interacting with the grille plate, and then the air nozzle rotates and generates different speeds, thereby continuously changing the air outlet direction and expanding the air outlet area.

[0062] In one embodiment, the inclination angles between the grille plates of different lengths and the air outlet 201 are different. The grille plates of different lengths and different inclination angles can make the effect of the rotation torque more obvious when the airflow passes through, so that the rotating air nozzle 200 can rotate autonomously more easily.

[0063] According to an embodiment of the utility model, the grille plate 230 is movably mounted with the air guide component 220 and the first matching portion 210, so that the inclination angle between the grille plate and the air outlet 201 is adjustable. It is understandable that the air outlet effect of the rotating air nozzle 200 can be adjusted by adjusting the inclination angle between the grille plate and the air outlet 201, and the air outlet effect includes the air outlet angle, air flow speed and air outlet range, and the rotation speed of the rotating air nozzle 200 can also be adjusted.

[0064] It is understandable that the direction and speed of air flow can be better controlled by adjusting the inclination angle between the grille plate and the air outlet 201. Different inclination angles between different grille plates and the air outlet 201 can also make different grille plates receive different driving forces when air flows through, generating a rotation torque to make the rotating air nozzle 200 rotate autonomously.

[0065] According to an embodiment of the present invention, the air outlet 201 of the rotating air nozzle 200 is provided with a plurality of grille plates 230, at least part of the grille plates 230 forms a first grille area, and the first grille area is suitable for driving the rotating air nozzle 200 to rotate relative to the mounting base 110 under the impetus of airflow.

[0066] It can be understood that by setting a first grille area with a grille plate 230 at the air outlet 201, when the air flow passes through the grille plate 230, the longer grille plate is pushed by a greater force than the smaller grille plate, thereby forming a rotational torque, so that the rotating air nozzle 200 can rotate automatically under the push of the air flow.

[0067] Since the rotating nozzle 200 can rotate automatically under the impetus of airflow, no additional motor drive is required, which can save energy and reduce the use cost. The automatic rotation function can make the airflow more evenly distributed in the blowing range, improve the blowing effect, and ensure that the hair is dried more quickly and evenly.

[0068] The grille plates of the first grille area have the same inclination direction. In other words, the grille plates of the first grille area are all arranged at the air outlet 201 in a clockwise or counterclockwise manner.

[0069] According to one embodiment of the utility model, the mounting seat 110 and the rotating air nozzle 200 are connected via a bearing 500, one of the mounting seat 110 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 110 and the rotating air nozzle 200.

[0070] It is understandable that the connection between the mounting seat 110 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 seat 110 .

[0071] According to an embodiment of the utility model, a housing 120 is further included, a mounting base 110 is connected to the housing 120, a mounting cavity is formed between the mounting base 110 and the housing 120, and the rotating air nozzle 200 is at least partially disposed in the mounting cavity. It can be understood that the mounting base 110 composed of the mounting 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 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.

[0072] In one embodiment, the rotating nozzle 200 is partially located in the installation cavity, and the air outlet 201 of the rotating nozzle 200 extends out of the installation cavity. Since the air outlet 201 extends out of the installation cavity, the air outlet 201 is not restricted by the installation cavity, so that the blowing area of ​​the air outlet 201 can be larger.

[0073] Of course, the rotating air nozzle 200 can also be completely located in the installation cavity, and the installation cavity can provide protection for the rotating air nozzle 200 and prevent the user from accidentally touching the rotating air nozzle.

[0074] 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.

[0075] 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.

[0076] In one embodiment, at least one of the body and the mounting base 110 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 110 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.

[0077] 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 110 .

[0078] 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.
