[0022] The following further describes the present utility model in detail with reference to the embodiments:

[0023] Embodiment 1

[0024] As Figures 1-4 shown, the utility model provides a foldable floor fan, including a lifting mechanism 1. One end of the lifting mechanism 1 is fixedly connected with a connecting mechanism 2, and one side of the connecting mechanism 2 is fixedly connected with a dust-proof mechanism 3. The lifting mechanism 1 includes a storage base 11. A vertical rod 12 is arranged on the storage base 11. One end of the vertical rod 12 is provided with a threaded hole 13. A positioning bolt 14 is threadedly connected inside the threaded hole 13. One end of the positioning bolt 14 is fixedly connected with a rubber pad 15. A screw rod 16 is threadedly connected inside the vertical rod 12. One end of the screw rod 16 is fixedly connected with a fan head 17. A positioning hole is opened on the back of the fan head 17;

[0025] Specifically, after unfolding the floor fan, rotate the fan head 17. By means of the connecting block 21 and the connecting rod 23, the screw rod 16 is driven to rotate synchronously, so that the height of the fan head 17 can be adjusted. Since the thread inside the vertical rod 12 engages with the thread on the surface of the screw rod 16, after stopping the rotation, the height of the fan head 17 can be fixed. Subsequently, rotate the positioning bolt 14 so that the positioning bolt 14 moves into the threaded hole 13, and at the same time drives the rubber pad 15 to fit with the screw rod 16, improving the fixing strength of the screw rod 16, thereby improving the stability of the floor fan during use, and further improving the practicality of the floor fan.

[0026] Embodiment 2

[0027] As Figures 1-4 shown, on the basis of Embodiment 1, the present utility model provides a technical solution: Preferably, the connecting mechanism 2 includes a connecting block 21, the connecting block 21 is fixedly connected to the fan head 17, arc-shaped positioning grooves 22 are formed inside the connecting block 21 and the storage base 11, a connecting rod 23 is rotatably connected inside the connecting block 21 and the storage base 11, both the storage base 11 and the screw rod 16 are fixedly connected to the connecting rod 23, a return spring 24 is fixedly connected to the surface of the connecting rod 23, one end of the return spring 24 is fixedly connected to a hollow rubber clamping block 25, the bottom of the hollow rubber clamping block 25 is fixedly connected to the surface of the connecting rod 23, and the hollow rubber clamping block 25 is sleeved inside the arc-shaped positioning groove 22;

[0028] Specifically, rotate the vertical rod 12 and the fan head 17 around the connecting rod 23 so that the vertical rod 12 and the fan head 17 are on the same straight line, drive the connecting rod 23 to rotate inside the storage base 11 and the connecting block 21, and at the same time drive the hollow rubber clamping block 25 to enter the arc-shaped positioning groove 22. After the pressure on the return spring 24 disappears, the hollow rubber clamping block 25 is pushed upward to improve the fitting degree between the hollow rubber clamping block 25 and the arc-shaped positioning groove 22, thereby fixing the position of the connecting rod 23, and further improving the stability of the folding floor fan. When the fan needs to be folded, rotate the fan head 17 so that the screw rod 16 completely enters the vertical rod 12, and then fold the fan head 17 backward, thereby driving the connecting block 21 to rotate on the connecting rod 23. Since the external force applied to the fan head 17 is greater than the elastic force of the return spring 24, the hollow rubber clamping block 25 can be driven to move out of the arc-shaped positioning groove 22, and the fan head 17 can be folded with the vertical rod 12. Subsequently, push the vertical rod 12 forward so that its bottom end rotates around the connecting rod 23, so that the vertical rod 12 enters the storage base 11, and further drives the fan head 17 to enter the storage base 11, and the folding of the floor fan can be completed.

The positioning rod 32 and the anti-slip pad 33 are sleeved in the positioning holes inside the fan head 17. The inner wall of the connecting frame 31 is fixedly connected with a dust-proof net 34. A first connecting plate 35 is fixedly connected to the connecting frame 31. A connecting bolt 36 is threadedly connected inside the first connecting plate 35. One end of the connecting bolt 36 is threadedly connected with a second connecting plate 37. The second connecting plate 37 is fixedly connected to the fan head 17;

[0031] Specifically, unscrew the connecting bolt 36 from the second connecting plate 37, and then pull the connecting frame 31 outwards, driving the positioning rod 32 and the anti-slip pad 33 to move out of the positioning holes at the rear of the fan head 17, so that the dust-proof net 34 can be removed for cleaning, thus avoiding excessive dust from affecting the use of the fan. At the same time, only the dust-proof net 34 needs to be disassembled, and then the overall disassembly of the fan head 17 is avoided, making the cleaning more convenient.

[0032] Next, the working principle of this foldable floor fan will be specifically described.

[0033] As Figures 1-4 shown, rotate the vertical rod 12 and the fan head 17 around the connecting rod 23 as an axis, so that the vertical rod 12 and the fan head 17 are in the same straight line, driving the connecting rod 23 to rotate inside the storage base 11 and the connecting block 21, and at the same time driving the hollow rubber block 25 into the arc-shaped positioning groove 22. After the pressure on the return spring 24 disappears, push the hollow rubber block 25 upwards to improve the fit between the hollow rubber block 25 and the arc-shaped positioning groove 22, thereby fixing the position of the connecting rod 23 and making the floor fan in an upright state. Rotate the fan head 17, and drive the screw rod 16 to rotate synchronously through the connecting block 21 and the connecting rod 23, so that the height of the fan head 17 can be adjusted. Rotate the positioning bolt 14, so that the positioning bolt 14 moves into the threaded hole 13, and at the same time drive the rubber pad 15 to fit with the screw rod 16 to improve the stability of the floor fan during use. Unscrew the connecting bolt 36 from the second connecting plate 37, and then pull the connecting frame 31 outwards, driving the positioning rod 32 and the anti-slip pad 33 to move out of the positioning holes at the rear of the fan head 17, so that the dust-proof net 34 can be removed for cleaning, thus avoiding excessive dust from affecting the use of the fan.
