[0026] The heat dissipation component 11 includes two second gears 1101. The two second gears 1101 are symmetrically arranged on the left side of the chassis 4. The first gear 10 is meshed with the two second gears 1101. A rotating rod 1102 is provided on one side of the second gear 1101. One end of the rotating rod 1102 penetrates through the chassis 4 and is provided with a second fan blade 1103. By driving the rotating rod 8 to rotate by the driving motor 7, the first gear 10 can be synchronously driven to rotate. Cooperating with the two meshed second gears 1101, the rotating rod 1102 and the second fan blade 1103 can be driven to blow air into the interior of the chassis 4, accelerating the air flow around the driving motor 7 and improving the heat dissipation effect of the driving motor 7 itself;

[0027] A number of evenly spaced through holes are provided on the surface of the heat dissipation fins 12, and the material of the heat dissipation fins 12 is aluminum alloy. The surface of the heat dissipation fins 12 adopts a porous structure design, increasing the heat dissipation area and improving the heat dissipation efficiency.

By driving the worm 1505 to rotate through the knob 1506 and cooperating with the worm gear 1504, the rotating column 1501 can be driven to rotate. By rotating the rotating column 1501, the first gear 1502 can be synchronously driven to rotate, and cooperating with the tooth grooves 1503, the support column 3 can move inside the sleeve 2, so as to facilitate adjusting the height of the floor fan itself to meet the needs of users. At the same time, the worm 1505 and the worm gear 1504 have a self-locking effect to prevent the support column 3 from displacing inside the sleeve 2 and ensure the use of users.

[0034] Immediately control the driving motor 7 to work. The output shaft of the driving motor 7 drives the rotating rod 8 to rotate, that is, drives the first fan blade 9 to rotate, meeting the user's blowing demand. At the same time, the rotation of the rotating rod 8 can synchronously drive the first gear 10 to rotate. Since the first gear 10 is meshed with two second gears 1101, it drives the rotating rod 1102 and the second fan blade 1103 to rotate simultaneously, capable of blowing air at the chassis 4, and then accelerating the air flow around the driving motor 7 and improving the heat dissipation effect of the driving motor 7. At the same time, heat dissipation fins 12 are provided on the surface of the driving motor 7, and the surface of the heat dissipation fins 12 is designed with a porous structure, increasing the heat dissipation area and improving the heat dissipation efficiency.
