Embodiment example 1

[0025] Implementation Case 1: A shock-absorbing electric lifting fan, including a base 1 and a fan 7, the fan 7 is arranged on the base 1, a lifting assembly is arranged between the base 1 and the fan 7, and the lifting assembly Including servo motor 11, screw rod 2, lifting plate 5, lifting rod 8 and telescopic rod 4, the base 1 is provided with a mounting groove, the servo motor 11 is arranged in the mounting groove, and the upper end of the servo motor 11 is connected by transmission The screw rod 2, the upper end of the screw rod 2 is threadedly connected to the lifting plate 5, the lifting rod 8 is fixedly connected to the lifting plate 5, the upper end of the lifting rod 8 is fixedly connected to the fan 7, and the lifting plate 5 The telescopic rod 4 is arranged between the base 1, and the noise reduction assembly is arranged between the driving motor 11 and the mounting seat. The noise reduction assembly includes a damping plate 12, a shock absorbing spring 13 and a rub...

Embodiment example 2

[0027] Implementation Case 2: This implementation is further optimized on the basis of Embodiment 1. This embodiment focuses on the improvements compared with Embodiment 1, and the similarities will not be repeated. Further optimization of the present invention, the screw 2 The upper end of the screw rod 2 is provided with an upper limit block 9, and the lower end of the screw rod 2 is provided with a lower limit block 10. By being provided with an upper limit block 9 at the upper end of the screw rod 2, the upper limit block 9 prevents the lifting plate 5 from colliding with the described The installation plate collides and damages the access control components, reducing potential safety hazards and improving safety; the lower end of the screw rod 2 is provided with a lower limit block 10, and the lower limit block 10 prevents the lifting plate 5 from colliding with the servo motor 11 during the descent process. Servo motor 11 reduces potential safety hazards and improves prac...

Embodiment example 3

[0028] Implementation Case 3: This implementation is further optimized on the basis of Embodiment 1. This embodiment focuses on the improvements compared with Embodiment 1, and the similarities will not be repeated. The further optimization of the invention, the lift assembly The outer side is covered with a telescopic sleeve, the telescopic sleeve includes an upper sleeve 6 and a lower sleeve 3, the upper side of the upper sleeve 6 is fixedly connected to the fan 7, and the upper sleeve 6 is sleeved with the lower sleeve 3. The upper sleeve 6 is slidably connected to the lower sleeve 3, and the lower side of the lower sleeve 3 is fixedly connected to the base 1. A telescopic sleeve is provided on the outer side of the lifting assembly, and the upper and lower sleeves can slide up and down. The upper sleeve 6 and the lower sleeve 3 improve the stability between the fan 7 and the base 1, and can be protected by the servo components to improve the service life of the servo compon...

Description

technical field [0001] The invention belongs to the technical field of electric fans, and in particular relates to a shock-absorbing electric lifting fan. Background technique [0002] Existing lift fans often use the following structures to achieve manual lift adjustment. Commonly, the height of the fan is adjusted by fixing with a single screw, or the height of the fan is adjusted by a lever-type button set on the center column; these structures are easy for users to adjust. In the actual application process, due to the material and cost control, the shaking range is very large, giving people a feeling of instability, and the user needs to be close to the fan when adjusting, and hold it with one hand Hold the lift pipe and adjust and fix it with one hand, but the lift pipe installed with fan cover and fan blades is generally relatively heavy, and the user often takes more effort when adjusting. [0003] Moreover, the existing fan usually uses a motor to drive the automati...
