[0010] In an embodiment, the stop assembly includes a first elastic member, a damping ejector rod and a second elastic member. The first elastic member elastically abuts between the damping ejector rod and the base assembly. One end of the damping ejector rod away from the base assembly is used to abut against the limiting groove. The second elastic member is connected between the fan main body and the base assembly. When the fan main body rotates downward relative to the base assembly, the second elastic member can be deformed to provide an upward elastic supporting force for the fan main body, so that the fan main body can be rotatably arranged up and down on the base assembly.

[0011] In one embodiment, the base assembly includes a base and a bracket. The bracket is disposed on the base, and the chuck is disposed on the bracket. The second elastic member includes a torsion spring body, a first elastic leg, and a second elastic leg connected to the torsion spring body.

[0013] In one embodiment, the hair dryer further includes a connecting member. The fan body is provided with a first shaft hole, the bracket is provided with a second shaft hole, and the chuck is provided with a third shaft hole. The connecting member is rotatably inserted through the first shaft hole, the second shaft hole, and the third shaft hole. The fan body, the bracket, and the chuck are all rotatably sleeved on the connecting member.

[0014] In one embodiment, a plurality of buckles are provided circumferentially on one side of the chuck close to the bracket. A barb protrudes from one end of the buckle away from the second shaft hole. The barb cooperates with the second shaft hole to clamp the chuck to the bracket.

[0015] In one embodiment, the inner ring portion is arranged circumferentially along the second shaft hole. The chuck is provided with a second mounting member. The second mounting member is arranged circumferentially along the third shaft hole. The inner wall of the second mounting member is attached to the outer wall of the inner ring portion to mount the chuck on the bracket.

[0016] In one embodiment, a first limiting member and a second limiting member are oppositely arranged in the up-down direction on an inner side wall of the fan body close to the chuck.

[0018] In the technical solution of the present utility model, by providing a plurality of limiting grooves on the fan assembly and combining with the elastic telescopic design of the stopping component, when the user adjusts the blowing angle, a clear gear feeling can be felt, and the hair dryer can be quickly and accurately fixed at the required blowing angle, without worrying about the random change of the blowing angle, improving the convenience and accuracy of use. The elastic design of the stopping component, while ensuring the flexibility of adjustment, also ensures the stable locking of the fan assembly at the selected angle. Even under high-power operation, vibration can be reduced, avoiding potential safety hazards caused by the shaking of the fan, and enhancing the safety and stability during use. Compared with the traditional direct friction locking method, the elastic stopping design reduces the hard contact and friction between parts, thus effectively reducing the noise during operation and creating a quieter use environment for the user. At the same time, the application of elastic materials also reduces wear and extends the service life of the hair dryer. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The present utility model provides a hair dryer.

[0036] Please refer to Figures 1 to 9 , in an embodiment of the present utility model, a hair dryer includes:

[0037] A base assembly 10;

[0038] A fan assembly 20 rotatably disposed on the base assembly 10, and a plurality of limiting grooves 21 are provided along the rotation direction of the fan assembly 20;

[0039] A stopping assembly 30 elastically telescopically disposed between the base assembly 10 and the fan assembly 20;

[0040] When the fan assembly 20 rotates, the stopping assembly 30 can be elastically deformed to sequentially abut against the plurality of limiting grooves 21 to limit the rotation angle of the fan assembly 20.

[0041] The scheme of the present application discloses a hair dryer, including a base assembly 10, a fan assembly 20 and a stop assembly 30, wherein the elastic and retractable characteristics of the stop assembly 30 and the plurality of limit grooves 21 on the fan assembly 20 are sequentially abutted to adjust the rotation angle of the fan assembly 20. It can be understood that the base assembly 10 is the supporting structure of the hair dryer, which is usually fixed on a wall or other vertical plane to provide a stable foundation for the entire hair dryer. The base assembly 10 not only needs to bear the weight of the fan assembly 20, but also needs to ensure the stability of the fan assembly 20 during operation. The fan assembly 20 includes core components such as fan blades and a motor that drives it to rotate. It is installed on the base assembly 10 and can rotate around a center point so that the user can adjust the direction of air supply as needed. In particular, the fan assembly 20 is provided with a plurality of limit grooves 21 along its rotation direction, and these limit grooves 21 play the role of preset position marks, which are used to limit the rotation range of the fan and maintain it at a specific angle. The stop assembly 30 is an elastic and retractable device, which is arranged between the base assembly 10 and the fan assembly 20. When the fan assembly 20 rotates, the stop assembly 30 can be elastically deformed as needed, contact and engage with the limit slots 21 one by one, and each limit slot 21 corresponds to a preset angle position. Through the close combination of the stop assembly 30 and the limit slot 21, the fan rotation angle is effectively limited, and the fan angle is accurately positioned. Therefore, when adjusting the fan angle, the user does not need to fix it with force or worry about the fan head changing position due to external force shaking. Compared with the traditional mechanical locking mechanism, the elastically retractable stop assembly 30 reduces wear and extends the service life of the product. At the same time, the design simplifies the structure, may reduce the failure rate, and is easier to maintain. In addition, through precise limit control, the risk of falling off caused by excessive rotation of the fan can be effectively prevented, especially in families with children or pets, which is particularly important and increases the safety of use. And because the limit slots 21 can be set in number and position as needed, this design provides a high degree of customization for electric fans of different sizes and different usage scenarios, meeting a wider range of market needs. It can be seen that the hair dryer provides a stable installation platform through the base assembly 10, the fan assembly 20 realizes the air supply function and angle adjustment, and the stop assembly 30 ensures the accuracy and stability of the fan positioning at different angles with an innovative elastic limiting mechanism, thereby improving the user experience.

[0042] Please refer to Figures 1 to 9 In one embodiment of the utility model, the fan assembly 20 includes a fan body 22 and a chuck 23. The fan body 22 can be rotatably arranged on the base assembly 10. The chuck 23 is transmission-connected to the fan body 22 and can rotate with the fan body 22. The chuck 23 is provided with a plurality of limit grooves 21 along its rotation direction. The stop assembly 30 can be elastically and telescopically arranged between the base assembly 10 and the chuck 23.

[0043] By arranging the limiting groove 21 on the chuck 23 instead of directly on the fan main body 22, the design of the fan main body 22 can focus more on wind output and aesthetics, while the chuck 23 is specifically responsible for the transmission and limiting functions. This not only makes the division of labor among the components clear, but also helps to improve the strength and stability of the overall structure. Among them, as an intermediate part connecting the fan main body 22 and the base assembly 10, the chuck 23 makes the installation and disassembly of the fan main body 22 more convenient, which is beneficial to daily cleaning and maintenance or replacement of damaged parts, reducing the maintenance cost of users. It can be understood that the chuck 23 is in transmission connection with the fan main body 22, which can be in the form of gear, belt or other transmission methods. Such a design can more precisely control the rotation speed and stability of the fan, while ensuring that the cooperation between the limiting groove 21 and the stop assembly 30 is more accurate, improving the transmission efficiency and positioning accuracy of the entire system. Moreover, since the stop assembly 30 acts directly on the chuck 23 rather than the fan main body 22 itself, this not only reduces the interference with the structure of the fan main body 22, but also may make the operation of the limiting system more reliable, reducing the influence of the vibration generated when the fan main body 22 rotates on the limiting effect, and ensuring the smoothness and durability of the limiting action.

[0044] Please refer to Figures 1 to 9 In an embodiment of the present invention, the stop assembly 30 includes a first elastic member 31, a damping ejector rod 32 and a second elastic member 33. The first elastic member 31 is elastically abutted between the damping ejector rod 32 and the base assembly 10. One end of the damping ejector rod 32 away from the base assembly 10 is used to abut against the limiting groove 21. The second elastic member 33 is connected between the fan main body 22 and the base assembly 10. When the fan main body 22 rotates downward relative to the base assembly 10, the second elastic member 33 can be deformed to provide an upward elastic supporting force for the fan main body 22, so that the fan main body 22 can be rotatably arranged up and down on the base assembly 10.

[0045] The stop component 30 of this solution is designed by combining a double elastic member (the first elastic member 31 and the second elastic member 33) with a damping ejector rod 32, achieving precise multi-dimensional control and stable support for the fan assembly 20. It can be understood that in addition to the original left and right rotation limiting function, the newly added second elastic member 33 enables the fan body 22 to have the ability to adjust up and down, realizing the tilting adjustment of the fan in the vertical direction, expanding the air supply range and applicable scenarios, and improving the user experience. The use of the first elastic member 31 and the second elastic member 33 provides double elastic support and buffering, not only providing elastic support for the fan assembly 20 in the up and down directions, but also providing a buffering effect when the fan rotates and stops, reducing impact and noise, and extending the service life of the product. Coupled with the introduction of the damping ejector rod 32, it can provide an additional positioning blocking effect when the fan rotates to the position of the limit slot 21, slowing down the impact at the moment of contact, and at the same time helping to improve the accuracy of the limit, ensuring that the fan can stop stably at the preset angle and will not be easily displaced due to a small external force. Therefore, through the double elastic member and the damping mechanism, users will feel a smoother and more feedback operation feel when adjusting the fan angle, increasing the comfort and satisfaction of use.

[0046] Please refer to Figures 1 to 9 , in an embodiment of the present invention, the base assembly 10 includes a base 11 and a bracket 12, the bracket 11 is provided on the base 12, the chuck 23 is provided on the bracket 11, the second elastic member 33 includes a torsion spring body 331 and a first elastic leg 332 and a second elastic leg 333 connected to the torsion spring body, the torsion spring body 331 is installed between the bracket 11 and the chuck 23, the first elastic leg 332 extends to the fan body 20, the second elastic leg 333 is clamped with the base 11, the fan body 22 is rotatably provided on the bracket 12, and when the fan body 22 rotates, it can drive the chuck 23 to rotate.

[0047] By dividing the base assembly 10 into two parts, namely the base 11 and the bracket 12, with the bracket 11 installed on top of the base 12, this hierarchical design not only optimizes space utilization but also enhances the stability of the entire electric fan and its load-bearing capacity for the fan body 22, enabling the fan to work stably at various angles. The second elastic member 33 adopts a design that combines a torsion spring body 331 with elastic feet (the first elastic foot 332 and the second elastic foot 333). The torsion spring body 331 is installed between the bracket 11 and the chuck 23, providing not only elastic support in the up and down directions but also effectively absorbing vibrations during rotation and reducing noise. This design is more complex and efficient than traditional single springs or elastic elements, ensuring the smoothness and restoring force of the fan body 22 during up and down rotation, thus enhancing the user experience. The fan body 22 realizes a more flexible rotation function through the transmission connection with the chuck 23. When the fan body 22 rotates, the chuck 23 rotates accordingly, and the first elastic foot 332 in the second elastic member 33 extends to the fan body 20. This linkage design not only ensures the smoothness of rotation but also increases the stability of the entire system in the vertical direction through the clamping connection of the second elastic foot 333 with the base 11, preventing excessive swinging. Through the above design, when the user adjusts the vertical angle of the fan, the fan can be fixed at the desired position without much effort, and the position remains stable without easily shifting.

[0048] Please refer to Figures 1 to 9 , in an embodiment of the present utility model, the bracket 12 includes a first limiting portion 121, a mounting plate 122 and an inner ring portion 123 disposed opposite to the chuck 23. The first limiting portion 121 extends circumferentially along the periphery of the mounting plate 13. The inner ring portion 123 is spaced apart from the first limiting portion 121 on the mounting plate 13. The first limiting portion 121 and the mounting plate 122 enclose a rotary clamping groove 124 for accommodating the chuck 23, and the torsion spring body 331 is accommodated within the inner ring portion 123.

[0049] By adding a first limiting portion 121, a mounting plate 122, and an inner ring portion 123 to the bracket 12, a more robust frame structure is formed. Such a design not only enhances the load-bearing capacity of the bracket but also ensures the stability and safety during the rotation of the fan body 22, especially effectively preventing shaking or accidental slipping when the fan is at different tilting angles. The rotary clamping groove 124 is formed by the enclosure of the first limiting portion 121 and the mounting plate 122. This design ingeniously provides a track for positioning and rotation of the chuck 23, ensuring the smoothness of the rotation process of the fan assembly 20 and the accuracy of positioning. Such a design reduces unnecessary friction, improves the smoothness of rotation, and also simplifies the installation process between the chuck 23 and the bracket 12. The setting of the inner ring portion 123 provides an internal installation space for the torsion spring body 331. Such an integrated design not only makes the overall structure more compact but also facilitates the installation and maintenance of the torsion spring body 331, reduces external interference, protects the torsion spring from the external environment, and extends its service life. This design rationally utilizes space and may also make the appearance of the electric fan more concise and smooth, without redundant exposed components, enhancing the overall aesthetics and user acceptance of the product.

[0050] Please refer to Figures 1 to 9 , in an embodiment of the present utility model, the hair dryer further includes a connecting member 40. The fan body 22 is provided with a first shaft hole 221, the bracket 12 is provided with a second shaft hole 125, the chuck 23 is provided with a third shaft hole 231, and the connecting member 40 is rotatably disposed in the first shaft hole 221, the second shaft hole 125, and the third shaft hole 231. The fan body 22, the bracket 12, and the chuck 23 are all rotatably sleeved on the connecting member 40.

[0051] The connecting member 40 passes through the first shaft hole 221 of the fan body 22, the second shaft hole 125 of the bracket 12, and the third shaft hole 231 of the chuck 23 at the same time. Such a design tightly and stably connects the three main components together, making the rotation of each component more synchronous and stable, reducing shaking or abnormal noise caused by the gaps between components, enhancing the quietness and reliability during use, and because all rotating components rotate around the same axis, ensuring the consistency and precise control of the rotation angles of each component. Therefore, using a single connecting member 40 as the rotation center, compared with the traditional multiple independent connection methods, greatly simplifies the assembly process, reduces the assembly difficulty, is also convenient for later maintenance and replacement of parts, improves production efficiency and the convenience of user self-maintenance. And, by centralizing the design of the connection structure, it may reduce the use of redundant components, optimize the internal space layout, help reduce the overall weight of the product, make the hair dryer lighter, and easier to carry and use.

[0052] Please refer toFigures 1 to 9 , in an embodiment of the present utility model, a plurality of buckles 24 are circumferentially arranged on one side of the chuck 23 close to the bracket 12. One end of the buckle 24 away from the second shaft hole 125 is convexly provided with a barb, and the barb cooperates with the second shaft hole 125 to snap the chuck 23 onto the bracket 12.

[0053] By arranging a plurality of buckles 24 on one side of the chuck 23 and designing barbs at the distal ends of the buckles 24, this structural design can, after the chuck 23 is inserted into the corresponding position of the bracket 12, utilize the barbs to form a physical engagement with the edge of the second shaft hole 125, greatly enhancing the connection firmness between the chuck 23 and the bracket 12 and preventing loosening or detachment caused by vibration or external force during use. The design of the buckles 24 and barbs allows the chuck 23 to be quickly and directly fixed to the bracket 12. Compared with the fixing method that requires screws or other fasteners, this design simplifies the assembly steps, reduces the assembly difficulty and time cost, and improves the production efficiency. Although the connection firmness is enhanced, this buckle 24 design also maintains a certain degree of detachability. When maintenance or adjustment is required, users or maintenance personnel can release the fixation of the buckle through simple operations and complete disassembly and assembly without special tools, improving the convenience of maintenance. Moreover, the barb structure ensures that even when the fan is running at high speed or is accidentally impacted, the chuck can remain stable, preventing component separation from causing safety hazards and increasing the use safety of the product.

[0054] Please refer to Figures 1 to 9 , in an embodiment of the present utility model, the inner ring portion 123 is arranged circumferentially along the second shaft hole 125. The chuck 23 is provided with a second mounting member 25, and the second mounting member 25 is arranged circumferentially along the third shaft hole 231. The inner wall of the second mounting member 25 is attached to the outer wall of the inner ring portion 123 to mount the chuck 23 on the bracket 12.

[0055] Through the circumferential fitting design of the second mounting member 25 and the inner ring portion 123, a more compact and precise docking between the chuck 23 and the bracket 12 is ensured. This fixing method with a larger direct contact surface can effectively reduce the deviation during installation, improve the stability of the overall structure, and maintain a good balance even when the fan is running at high speed. The fitting method of the second mounting member 25 and the inner ring portion 123 simplifies the assembly steps, eliminates the need for additional fasteners or complex assembly procedures, making the assembly process faster and easier to operate, and reducing the assembly cost and time. The direct circumferential fitting not only strengthens the connection stability but also makes the whole structure look more integrated, reduces gaps and unnecessary exposed components, improves the product's sealing performance, helps with dust and water protection, and enhances the product's appearance aesthetics. If adjustment or repair of the chuck 23 is required, this design makes disassembly and reinstallation relatively simple because there are not too many fasteners to deal with, and users or technicians can easily replace components or adjust their positions. This solution, through the circumferential fitting design of the second mounting member 25 and the inner ring portion 123, not only improves the installation accuracy and stability, simplifies the assembly process, but also enhances the product's sealing performance and appearance neatness, reflecting the optimization and innovation of the traditional installation method.

[0056] Please refer to Figures 1 to 9 In an embodiment of the present utility model, on an inner side wall of the fan body 22 close to the chuck 23, a first limiting member 222 and a second limiting member 223 are oppositely arranged in the up and down direction. A positioning member 232 is provided on an outer side wall of the chuck 23, and the positioning member 232 is located between the first limiting member 222 and the second limiting member 223. When the fan body 22 rotates, the first limiting member 223 and the second limiting member 223 cooperate to drive the chuck 23 to rotate.

[0057] Through the first limiting member 222 and the second limiting member 223 provided on the inner side wall of the fan body 22, and the positioning member 232 on the outer side wall of the chuck 23, an accurate interaction mechanism is formed. This design enables the fan body 22, when rotating, not only to control the rotation range through the limiting members but also to ensure that the chuck 23 accurately follows the rotation of the fan body 22, improving the overall regulation accuracy of the fan. The interaction between the first limiting member 222, the second limiting member 223, and the positioning member 232 not only limits the rotation angle of the fan body 22 but also increases the stability during rotation, avoiding structural damage or safety hazards caused by excessive rotation, and enhancing the product's use safety and reliability. Through this mechanical limiting and positioning design, the need for external complex control systems is reduced, and the accurate control of the rotation of the chuck 23 can be achieved using the structure of the fan body 22 itself, simplifying the overall design, reducing the manufacturing cost, and the maintenance difficulty.

[0058] Please refer to Figures 1 to 9 , in an embodiment of the present utility model, the outer periphery of the chuck 23 has a circumferentially arranged transmission area 233 and a non-transmission area 234, and a plurality of the limiting grooves 21 are arranged in the transmission area 33 in a circumferential arrangement.

[0059] By specifically arranging the limiting grooves 21 within the transmission area 233, it ensures that the force transmission during the transmission process is more concentrated and effective. Such a design can reduce the energy loss during the transmission process, making the rotation of the fan body 22 smoother and more precise. At the same time, it improves the sensitivity and accuracy of the interaction between the limiting component and the chuck. The existence of the non-transmission area 234 means that there is no direct mechanical transmission contact in these areas, reducing unnecessary friction, thereby reducing the wear and noise generated by friction, extending the service life of the fan assembly 20, and providing a quieter usage environment for users. This design provides more possibilities for the structural layout of the fan. The division of the transmission area and the non-transmission area can be optimized according to actual needs.

[0060] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present utility model.
