[0043] The technical scheme of the utility model is further illustrated in the following Figures 1 to 7 The technical scheme of the utility model is further illustrated in the following

[0044] A head-shaking fan comprises a base assembly 1, a support pipe 2, a fan head assembly 3 and a horizontal head-shaking driving assembly 4.

[0045] The horizontal head-shaking driving assembly 4 is arranged on the base assembly 1, and comprises a first motor 41, an outer-tooth driving wheel 42 and an inner-tooth driven wheel 43. The first motor 41 drives the outer-tooth driving wheel 42 to rotate, thereby driving the inner-tooth driven wheel 43 to rotate in the base assembly 1.

[0046] The lower end of the support pipe 2 is connected to the inner-tooth driven wheel 43, and the upper end of the support pipe 2 is provided with the fan head assembly 3.

[0047] The horizontal head-shaking driving assembly 4 is arranged on the base assembly 1, and the fan head assembly 3 is connected to the support pipe 2, thereby forming a stable support structure.

[0048] Further, the outer-tooth driving wheel 42 is arranged inside the inner-tooth driven wheel 43, the outer-tooth gear of the outer-tooth driving wheel 42 is engaged with the inner-tooth gear of the inner-tooth driven wheel 43, and the first motor 41 drives the outer-tooth driving wheel 42 to rotate, thereby driving the inner-tooth driven wheel 43 to rotate.

[0049] In the specific embodiment, the rotation axis is perpendicular to the horizontal plane.

[0050] In other embodiments, the rotation axis can also be non-perpendicular to the horizontal plane, and the rotation of the inner tooth driven wheel 43 drives the rotation of the support tube 2 and the fan head assembly 3 around the rotation axis by 360°.

[0051] Further, the lower end of the support tube 2 is provided with a connecting sleeve 21, and the connecting sleeve 21 is provided with a positioning block 211 near one end of the inner tooth driven wheel 43.

[0052] The top surface of the inner tooth driven wheel 43 is provided with a positioning groove 431, and the positioning block 211 is connected with the positioning groove 431.

[0053] The connection between the support tube 2 and the inner tooth driven wheel 43 is more stable and accurate through the cooperation of the connecting sleeve 21 and the positioning block 211 at the bottom of the connecting sleeve 21 with the positioning groove 431 on the top surface of the inner tooth driven wheel 43. This design effectively prevents problems such as unstable fan head shaking or abnormal noise caused by loose or misaligned connection, and improves the overall performance and user experience of the fan. Preferably, the positioning block 211 is located at the bottom of the connecting sleeve 21.

[0054] The connection between the support tube 2 and the inner tooth driven wheel 43 is more modular due to the design of the connecting sleeve 21 and the positioning block 211, and no additional connecting parts are needed, so that the disassembly and replacement work can be more convenient when maintenance or replacement of related parts is needed, effectively improving the maintainability and expandability of the fan.

[0055] Further, the base assembly 1 includes a lower support 11, an upper support 12, and a housing 13, the lower support 11 and the upper support 12 are arranged inside the housing 13, and the upper support 12 is mounted on the top of the lower support 11.

[0056] The upper support 12 is provided with a vertical channel 121 for plug-in cooperation with the connecting sleeve 21, and the connecting sleeve 21 is horizontally rotatably arranged in the vertical channel 121.

[0057] The horizontal head driving assembly 4 is located between the upper support 12 and the lower support 11.

[0058] By arranging the lower support 11 and the upper support 12 inside the housing 13 and arranging the horizontal head driving assembly 4 between them, a more stable and reliable base structure is formed. This design not only enhances the stability of the fan as a whole, but also provides better support and protection for the horizontal head driving assembly 4, prolonging its service life. The design of the housing 13 not only protects the base assembly 1, but also enhances the overall aesthetics of the fan. At the same time, the housing 13 can effectively prevent users or pets from contacting the internal components such as the horizontal head driving assembly 4, improving the safety of the fan.

[0059] The vertical channel 121 of the upper support 12 is designed to be inserted into the connecting sleeve 21, so that the support pipe 2 and the fan head assembly 3 thereon can rotate smoothly in the horizontal direction. At the same time, since the connecting sleeve 21 is horizontally rotatable in the vertical channel 121, this design reduces friction and resistance during the process of shaking the head, improves the performance and efficiency of the shaking drive.

[0060] Further, the inner tooth driven wheel 43 is located at the bottom of the upper support 12, and the inner tooth driven wheel 43 is a circular ring structure, and the inner ring wall of the circular ring structure is provided with a full circumferential inner tooth, and the rotation axis of the inner tooth driven wheel 43 is coaxially arranged with the central axis of the vertical channel 121.

[0061] The bottom of the upper support 12 is provided with a mounting arm 122, which is arranged to extend downward in the vertical direction, and the first motor 41 is mounted on the bottom of the upper support 12 through the mounting arm 122.

[0062] The top of the lower support 11 is provided with a avoiding area 111 for accommodating the first motor 41.

[0063] The inner tooth driven wheel 43 is located at the bottom of the upper support 12, and the rotation axis of the inner tooth driven wheel 43 is coaxially arranged with the central axis of the vertical channel 121, which ensures the stability and accuracy of the support pipe 2 and the fan head assembly 3 during the process of shaking the head.

[0064] In a specific embodiment, the bottom of the upper support 12 is provided with two mounting arms 122 extending downward in the vertical direction, and the first motor 41 is fixed on the bottom of the upper support 12 through these mounting arms 122. This design not only makes the installation of the first motor 41 more stable, but also facilitates the maintenance and replacement of the motor. At the same time, the design of the mounting arm 122 also takes into account the heat dissipation problem of the first motor 41, ensuring the normal operation of the first motor 41 during the working process.

[0065] The top of the lower support 11 is provided with a avoiding area 111 for accommodating the first motor 41. This design not only makes the structure of the entire base assembly 1 more compact, but also reduces the overall height of the fan and improves its space utilization. At the same time, the design of the avoiding area 111 also ensures that the first motor 41 will not interfere with the lower support 11 during the working process, improving the stability and safety of the fan.

[0066] Further, the fan head assembly 3 includes a fan head 31, a motor head 32 and a mounting portion 33.

[0067] The mounting portion 33 is mounted and connected with the upper end of the support pipe 2, and the mounting portion 33 is also mounted and connected with the motor head 32, and the motor head 32 is mounted at the rear of the fan head 31.

[0068] By integrating the fan head 31, motor head 32 and mounting part 33 together to form a fan head assembly 3, the structural integration of the entire fan is improved. This design not only makes the assembly process of the fan more concise and clear, but also helps to reduce the number and complexity of parts, thereby reducing production costs and maintenance difficulty.

[0069] The motor head 32 is installed at the rear of the fan head 31, which helps to optimize the distribution of air flow. When the motor head 32 drives the fan blades of the fan head 31 to rotate, it can produce air flow more uniformly, improving the air supply efficiency and comfort of the fan. At the same time, this design also helps to reduce the resistance of air flow inside the fan, reducing noise and energy consumption.

[0070] The mounting part 33 serves as a connecting component between the fan head assembly 3 and the support pipe 2, and its design not only ensures the stability of the connection, but also makes the movement of the fan head assembly 3 during the head-shaking process more stable. This design helps to reduce shaking and vibration during the head-shaking process, improving the stability and service life of the fan.

[0071] Further, the motor head 32 includes a motor bracket 321, a fan motor 322 and a vertical head-shaking drive assembly 323, the fan motor 322 and the vertical head-shaking drive assembly 323 are installed on the motor bracket 321, and the driving end of the fan motor 322 is connected with the fan blades of the fan head 31;

[0072] The vertical head-shaking drive assembly 323 includes a second motor 3231, a driving gear 3232 and a transmission gear 3233, the driving gear 3232 is arranged at the driving end of the second motor 3231, and the driving gear 3232 is engaged with the transmission gear 3233;

[0073] The motor bracket 321 is installed on the top of the mounting part 33 through a horizontal shaft 34, the transmission gear 3233 is installed on the horizontal shaft 34, and the second motor 3231 is used to drive the motor bracket 321 to rotate around the horizontal shaft 34.

[0074] By integrating the vertical head-shaking drive assembly 323 in the motor head 32, the fan not only has a horizontal head-shaking function, but also adds a vertical head-shaking function. This design greatly increases the air supply range and flexibility of the fan, and can better meet the user's needs in different scenarios.

[0075] The vertical head-shaking drive assembly 323 adopts the meshing transmission mode of the second motor 3231, the driving gear 3232 and the transmission gear 3233, which not only has a compact structure and high transmission efficiency, but also runs stably and has low noise. At the same time, by installing the motor bracket 321 on the top of the mounting part 33 through the horizontal shaft 34, the rotation of the motor bracket 321 around the horizontal shaft 34 can be realized, thereby realizing the vertical head-shaking function of the fan head.

[0076] It is worth mentioning that the motor support 321, as a supporting component of the fan motor 322 and the vertical head driving assembly 323, is designed not only to ensure the stable installation of these components, but also to make the movement of the entire fan head assembly 3 more stable during the head shaking process. This design helps to reduce shaking and vibration during the shaking process, improves the stability and service life of the fan.

[0077] Further, the motor head 32 further comprises a motor shell 324, which is detachably arranged at the rear of the fan head 31, and the motor support 321, the fan motor 322 and the vertical head driving assembly 323 are arranged inside the motor shell 324.

[0078] The motor shell 324 is annularly spaced with a plurality of first buckles 3241, and the rear of the fan head 31 is annularly spaced with a plurality of second buckles 311, and the first buckles 3241 and the second buckles 311 are connected by buckling.

[0079] The motor shell 324 is detachably arranged at the rear of the fan head 31, which makes it more convenient for users to maintain and replace the motor support 321, the fan motor 322 and the vertical head driving assembly 323 inside the motor head 32. When these components fail or need to be cleaned, users only need to simply disassemble the motor shell 324, without the need to disassemble the entire fan, greatly improving the convenience of maintenance. The design of the motor shell 324 not only considers the stability and maintainability of the structure, but also focuses on the optimization of air distribution. Through reasonable design of the motor shell 324, air flow can be guided more evenly through the fan head 31, improving air supply efficiency and comfort. At the same time, the motor shell 324 can also play a certain role in noise reduction, reducing the noise generated by the motor during operation.

[0080] Specifically, the motor shell 324 is connected to the second buckles 311 at the rear of the fan head 31 by the first buckles 3241, which not only makes the connection between the motor head 32 and the fan head 31 more stable, but also reduces noise and vibration caused by loose connection. At the same time, the buckle connection method also improves the impact resistance of the structure, making the fan more durable during long-term use.

[0081] Further, the housing 13 comprises a support bottom plate 131, a main shell 132 and a secondary shell 133, the main shell 132 is mounted on the top surface of the support bottom plate 131, and the secondary shell 133 is detachably mounted on one side of the main shell 132.

[0082] The top of the main shell 132 is provided with a first control module, and the top of the upper support 12 is provided with a first circuit board 51 corresponding to the first control module, and the first control module is used to trigger the first circuit board 51.

[0083] The auxiliary shell 133 is provided with a second control module, and the side of the upper support 12 is provided with a second circuit board 52 corresponding to the second control module, and the second control module is used to trigger the second circuit board 52.

[0084] The first circuit board 51 and the second circuit board 52 are respectively electrically connected with the first motor 41 and the second motor 3231.

[0085] By setting the main shell 132 and the auxiliary shell 133 on the shell 13, and respectively installing the first control module and the second control module on them, the user can control the fan from different positions. This design increases the flexibility of control, so that the user can choose a more convenient control method according to his own needs. The setting of the first control module (first circuit board 51) and the second control module (second circuit board 52) makes the control interface of the fan more intuitive and easy to operate. The user only needs to simply touch or press the buttons or touch areas on the control module to realize the operations such as turning on / off the fan, adjusting the wind speed, switching the head shaking mode, etc. This design greatly improves the user experience, making the use of the fan more convenient and efficient.

[0086] Specifically, the first circuit board 51 and the second circuit board 52 are respectively electrically connected with the first motor 41 and the second motor 3231. This design makes the maintenance of the circuit more convenient. When the circuit fails, the user only needs to simply disassemble the corresponding shell to quickly locate and replace or repair the circuit board without disassembling the entire fan.

[0087] Further, the detachable design of the main shell 132 and the auxiliary shell 133 not only facilitates the maintenance and replacement of the circuit, but also provides the possibility for the upgrade of the fan. When the fan needs to add new functions or improve existing functions, the user only needs to replace or upgrade the corresponding control module and circuit board.

[0088] Further, the inside of the lower support 11 is provided with a counterweight 14.

[0089] The counterweight 14 effectively reduces the vibration generated by the fan during operation by increasing the weight of the lower support 11 (base 1). Especially in the high wind mode or when the head is rotating, the fan can maintain a more stable state and is not easy to shake or fall over.
