[0029] It is understood that the folding fan provided in this embodiment of the present invention, by using shock-absorbing silicone to physically isolate the drive motor 130 from the fan rear shell 140, can significantly reduce the vibration propagation caused by the electromagnetic force of the drive motor 130, thereby effectively reducing the overall noise level of the fan during operation, especially electromagnetic noise, providing users with a quieter and more comfortable operating environment and improving the user experience. At the same time, the shock-absorbing silicone not only isolates noise but also absorbs some vibration, reducing the wear and tear on the drive motor 130's components caused by external impacts and internal vibrations, thus helping to extend the service life of the drive motor 130 and its connecting parts. On the other hand, this embodiment of the present invention allows the fan to be flexibly adjusted at different angles and heights through a telescopic mechanism, increasing the convenience and adaptability of the fan and meeting diverse user needs.

[0030] Furthermore, refer to Figure 2 According to some embodiments of this utility model, a mounting base 150 is provided on the inner side of the fan rear housing 140, and a mounting groove 151 is provided on the side of the mounting base 150 facing the fan front cover 110. The drive motor 130 is inserted into the mounting groove 151, and shock-absorbing silicone is provided between the drive motor 130 and the mounting base 150, thereby providing a stable mounting position for the drive motor 130, and further reducing vibration transmission through the shock-absorbing silicone, enhancing the noise reduction effect, helping to simplify the installation process and ensure the stable operation of the motor.

[0031] Furthermore, refer to Figure 2 According to some embodiments of this utility model, the shock-absorbing silicone is a silicone ring 160 disposed in the mounting groove 151. The inner wall of the silicone ring 160 is provided with a slot 161 in the circumferential direction. The outer peripheral wall of the end of the drive motor 130 near the rear shell 140 of the fan is provided with a corresponding protruding ring 131. The protruding ring 131 can be engaged with the slot 161, thereby improving the accuracy of installation and strengthening the fixing effect of the shock-absorbing silicone, ensuring that it is not easily displaced during long-term use, thereby maintaining good shock absorption performance.

[0032] Furthermore, according to some embodiments of the present invention, the silicone ring 160 and the mounting groove 151 are interference fit, and the convex ring 131 and the slot 161 are interference fit, thereby ensuring a tight connection between components, further reducing additional noise that may be caused by loosening, and improving the stability and reliability of the overall structure.

[0033] Furthermore, according to some embodiments of this utility model, the mounting base 150 is detachably and fixedly connected to the inner middle of the fan rear housing 140 by bolts, which facilitates maintenance and replacement of parts, while ensuring the firmness and stability of the drive motor 130 installation, and helps to extend the service life of the equipment.

[0034] Furthermore, refer to Figure 1and Figure 3 According to some embodiments of the present invention, the base 200 is provided with a slot 210, one end of the telescopic rod 300 is hinged to the rear end of the slot 210, and the telescopic rod 300 can be stored in the slot 210, thereby facilitating storage and saving space.

The sleeve 410 is fitted onto the telescopic rod 300 and can move up and down along the telescopic rod 300. A limiting block 220 is provided on the inner side wall of the groove 210. When the telescopic rod 300 is in a vertical state, the sleeve 410 can descend along the telescopic rod 300 so that the limiting plate 420 is located behind the limiting block 220. The limiting plate 420 can just abut against the limiting block 220, or there can be a certain gap between the limiting plate 420 and the limiting block 220 to prevent the telescopic rod 300 from rotating in the vertical plane, thereby ensuring the stability of the telescopic rod 300 in the vertical state, avoiding unnecessary rotation or sliding, and improving the safety of use. When unlocking is required, move the sleeve 410 upward along the telescopic rod 300 so that the limiting plate 420 moves away from the limiting block 220, thereby allowing the telescopic rod 300 to rotate around the hinge point.

[0036] Furthermore, refer to Figure 1 and Figure 3 According to some embodiments of the present invention, the base 200 has a built-in circuit board, and a control panel 230 is provided on one side of the slot 210 on the upper end surface of the base 200.
