[0047] A first driving assembly 3, connected to the fan assembly 1 and used to drive the fan assembly 1 to tilt relative to the mounting housing 2;

[0048] A second driving assembly 4 is connected to the first driving assembly 3 and the fan assembly 1 respectively and is used to drive the fan assembly 1 to rotate and shake relative to the mounting housing 2 at a predetermined tilt angle;

[0049] In this embodiment, the fan assembly begins to tilt through the first drive motor. When the fan assembly tilts to a preset tilt angle, the second drive assembly maintains the current tilt angle and begins to shake its head. The tilt angle can be determined according to the customer's air supply range requirements. After the tilt angle is determined, the fan assembly can shake its head 360 degrees, making the fan more intelligent and convenient, improving the user experience, and having more practical value.

[0050] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first drive component 3 includes a first drive motor 31, a first gear 32 connected to the output end of the first drive motor 31, and a second tooth member 33 arranged in an arc shape and connected to the fan component 1, the second tooth member 33 is provided with a gear rail 331 arranged along an arc shape and meshing with the first gear 32, and the second tooth member 33 is slidably connected to the second drive component 4 along an arc shape.

[0051] In this embodiment, the first drive motor drives the first gear to rotate, driving the second gear to tilt along an arc, so that the fan assembly begins to tilt.

The tilt angle can be determined according to the customer's air supply range requirements, and the tilt angle can be determined before shaking the head 360 degrees. This improves the user experience and has more practical value.

[0052] Further, as a preferred implementation mode of the present invention but not a limitation, when the fan is started, the first drive motor 31 rotates forward to drive the first gear 32 to rotate forward until it abuts against the end of the rack 331, so that the second gear 33 tilts forward to a maximum angle relative to the second drive assembly 4, thereby tilting the fan assembly 1 forward to a maximum angle relative to the mounting shell 2, the first drive motor 31 keeps rotating forward, and the first gear 32 pushes the second gear 33 to rotate forward synchronously, so that the second drive assembly 4 rotates forward, thereby driving the fan assembly 1 to rotate and shake its head at a maximum angle relative to the mounting shell 2;

[0053] When the fan is turned off, the first drive motor 31 reverses to drive the first gear 32 to reverse to the initial position corresponding to the rack 331, so that the second gear 33 remains parallel to the second drive assembly 4, and further the fan assembly 1 remains parallel to the mounting housing 2.

[0054] In this embodiment, when started, the first drive motor rotates forward to push the second gear to tilt the fan assembly to the maximum angle relative to the mounting housing, thereby achieving a 360° head shake. When turned off, the first drive motor rotates in the reverse direction to adjust the second gear in parallel, thereby keeping the fan assembly parallel to the mounting housing. This design enables the fan to achieve an intelligent 360° head shake effect during use, while maintaining overall parallelism when turned off, thereby improving the product's appearance and user experience, and enhancing the functionality of the fan.

[0055] Furthermore, as a preferred embodiment of the present invention but not a limitation, the second drive assembly 4 includes a second drive motor 41, a pinion 42 connected to the output end of the second drive motor 41, and a large gear 43 meshing with the pinion 42, and the second gear 33 is slidingly connected to the bottom of the large gear 43 and rotates synchronously with the large gear 43.

[0056] In this embodiment, the fan assembly realizes the shaking function through the engagement of the small gear and the large gear driven by the second drive motor. This structural design enables the second drive assembly to reliably transmit power to the fan assembly, realizing the shaking function while maintaining stability. Overall, this design improves the reliability and stability of the fan.

[0057] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the reduction ratio between the small gear 42 and the large gear 43 is M, the reduction ratio between the first gear 32 and the second gear 33 is N, and when the fan is turned on, the rotation directions of the first drive motor 31 and the second drive motor 41 are opposite, the rotation speed of the first drive motor 31 is X, and the rotation speed of the second drive motor 41 is NX / M.

[0058] In this embodiment, through this reduction ratio, when the second drive motor rotates, the first gear and the rack rail remain relatively stationary, thereby causing the fan assembly to shake its head 360° at the current predetermined tilt angle.

[0059] Furthermore, as a preferred implementation mode of the present invention but not a limitation, when the fan is started, the first drive motor 31 rotates forward at a speed of X, driving the first gear 32 to rotate forward, so that the second tooth 33 tilts forward to a predetermined angle relative to the second drive component 4, and then the second drive motor 41 reverses at a speed of NX / M, driving the small gear 42 to reverse, so that the large gear 43 drives the second tooth 33 to rotate and remain stationary relative to the first gear 32, thereby causing the fan component 1 to rotate and shake its head at a predetermined angle relative to the mounting shell 2.

[0060] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a guide rail cover 5, the guide rail cover 5 is provided with an arc-shaped portion 51, the second tooth member 33 is provided with an arc-shaped slider 332, the second drive assembly 4 is provided with a fan-shaped groove 44 for sliding connection of the arc-shaped slider 332, and the arc-shaped portion 51 is connected to the fan-shaped groove 44 to form a guide rail for sliding of the arc-shaped slider 332.

[0061] In this embodiment, the stability and accuracy of the second drive assembly are improved. Through the connection between the guide rail cover and the second drive assembly, a guide rail is formed for the arc-shaped slider to slide, which effectively guides and limits the motion range of the second gear. At the same time, the combination of the arc-shaped slider and the fan-shaped groove enhances the stability of the sliding connection, and also enhances its durability and stability, so that the user can adjust the wind direction more safely and conveniently when using the fan, thereby improving the overall quality of the product.

[0062] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a mounting box 6, and the fan assembly 1 includes a universal frame 11 rotatably connected to the mounting box 6, a main motor mounting frame 12 rotatably connected to the inner wall of the universal frame 11, a main motor 13 arranged in the main motor mounting frame 12, an impeller 14 connected to the output end of the main motor 13, and a front air outlet mesh 15 detachably connected to the main motor mounting frame 12.

[0063] In this embodiment, the stability and maintainability of the fan assembly are improved. The universal adjustment of the fan assembly is achieved through the rotational connection between the mounting box and the universal bracket, so that the fan can more flexibly adjust the blowing direction to meet the diverse usage needs of users. The detachable connection design of the main motor mounting bracket facilitates the maintenance and replacement of the main motor and impeller, improves the maintainability of the entire fan assembly, and enhances the practicality and user experience of the product.

[0064] Further, as a preferred implementation manner of the present solution but not limiting, the mounting housing 2 is provided with mounting grooves 21 for mounting the first drive motor 31 and the second drive motor 41 .

[0065] In this embodiment, through the reasonable design of the mounting groove, the first drive motor and the second drive motor can be effectively fixed and stabilized to prevent them from shaking or loosening during operation, thereby ensuring the normal operation of the fan. In addition, the presence of the mounting groove also makes assembly and maintenance more convenient, making it easier for users to replace and repair the motor components. Therefore, this design not only improves the mechanical structural strength of the entire fan, but also enhances the durability and maintainability of the product, thereby improving the user experience.

[0066] Furthermore, as a preferred implementation manner of the present solution but not a limitation, it also includes an adjustment module electrically connected to the first drive motor 31 and the second drive motor 41 and used to adjust the starting time difference between the first drive motor 31 and the second drive motor 41 .

[0067] In this embodiment, the inclination angle of the fan assembly is adjusted by changing the starting time difference of the first drive motor and the second drive motor so that it can shake its head 360° according to the angle required by the customer. After the first drive motor starts to rotate, the fan assembly starts to tilt from 0° to the maximum inclination angle. After the adjustment module recognizes that the preset angle is reached, the second drive motor starts to rotate, so that the first gear and the second gear remain relatively still, thereby causing the fan assembly to start shaking its head 360° at the current preset inclination angle.

[0068] Furthermore, as a preferred embodiment of the present invention but not a limitation, it also includes a connecting mechanism 7 for connecting the main motor mounting frame 12 and the front air outlet net 15, the connecting mechanism 7 includes a snap-in component 71 and a snap-in groove 72 for the snap-in component 71 to be snapped into, the snap-in groove 72 is L-shaped, the snap-in component 71 is arranged on the main motor mounting frame 12, and the snap-in groove 72 is arranged on the front air outlet net 15; or the snap-in component 71 is arranged on the front air outlet net 15, and the snap-in groove 72 is arranged on the main motor mounting frame 12.

[0069] In this embodiment, the stability and assembly convenience of the fan assembly are enhanced. Through the L-shaped card slot design, a reliable connection can be achieved between the main motor mounting frame and the front air outlet net, ensuring a tight fit between them. The flexibility of the setting position of the card connector can be selected to be set on the main motor mounting frame or the front air outlet net according to actual needs. Such a connection mechanism not only makes the fan more stable during operation, but also makes assembly and disassembly more convenient, improves the maintainability and user-friendliness of the product, and enhances the reliability of the overall structure.

[0070] The working principle of this embodiment is as follows:

[0071] The fan of the present application is an automatic angle adjustment fan, which drives the first gear to rotate through the first drive motor, drives the second gear to start tilting along the arc, so that the fan assembly starts to tilt, and when the fan assembly tilts to a preset tilt angle, the fan assembly is kept at the current tilt angle through the second drive assembly to start shaking the head, and the tilt angle can be determined according to the customer's air supply range requirements, and the fan shakes 360 degrees after the tilt angle is determined, which improves the user experience and has more practical value.
