[0023] Specifically, the height of the fan can be adjusted by moving the cylinder 4 toward the top, and the adjusted height can be fixed by moving the fixing column 10 toward the rear side to engage with the hole groove 11 above the cylinder 4. The angle in the vertical direction can be adjusted by rotating the cylinder 6, and the angle in the horizontal direction can be adjusted by rotating the hollow column 3, so that the fan can be adjusted at multiple angles and heights.

[0024] Reference Figure 3 The moving mechanism 2 includes a plurality of fixed plates 201, which are fixedly connected to the four ends of the bottom of the base 1, the bottom of the fixed plates 201 is rotatably connected to a rotating column 202, the bottom of the rotating column 202 is fixedly connected to a concave plate 203, the inner wall of the concave plate 203 is rotatably connected to a roller 204, the left side of the inner wall of the concave plate 203 is rotatably connected to an L-shaped plate 205, and the top of the L-shaped plate 205 is fixedly connected to a pedal 206;

[0025] Specifically, the rotation of the rotating column 202 can facilitate the turning of the rotating roller 204, and the movement of the fan can be achieved by the rolling of the roller 204 on the concave plate 203. The pedal 206 can make the L-shaped plate 205 rotate, and the plate at the bottom will contact the roller 204, causing the roller 204 to stop rotating, thereby preventing it from continuing to move.

[0026] Reference Figure 1 and Figure 2 A controller 16 is fixedly connected to the right side of the top of the base 1, and the controller 16 is electrically connected to the servo motor 8; a housing 17 is fixedly connected to the outside of the controller 16, and a dust cover 18 is rotatably connected to the top of the housing 17;

[0027] Specifically, the controller 16 can control the start-up and operating power of the servo motor 8, the housing 17 can prevent the controller 16 from being damaged by collisions, and the dust cover 18 can prevent dust from entering the controller 16 and damaging its internal electronic components.

[0028] Reference Figure 1 and Figure 2A ring 13 is fixedly connected to the rear side of the outer wall of the hollow column 3, and a buckle 14 is slidably connected to the inner wall of the ring 13. A plurality of clamping holes 15 are provided on the top of the base 1, and the buckles 14 are engaged with the clamping holes 15; a hanging column 21 is fixedly connected to the front side of the U-shaped plate 5, and a thermometer 20 is arranged on the outer side of the hanging column 21; a filter screen 22 is fixedly connected to the front and rear sides of the inner wall of the cylinder 6; an air monitor 19 is fixedly connected to the left side of the top of the base 1;

[0029] Specifically, by the mutual engagement between the card hole 15 and the buckle 14, the horizontal rotation angle can be fixed to prevent accidental rotation. The surrounding temperature can be known through the thermometer 20, the air blown out by the fan can be filtered through the filter net 22, and the surrounding air quality can be understood through the air monitor 19.

[0030] Working principle: Before using the device, first of all, the movement of the cylinder 4 is the key component of the height adjustment of the fan. By moving the cylinder 4 up or down, the height of the fan can be easily adjusted to adapt to different usage scenarios. Then, in order to fix the adjusted height, a fixing column 10 is needed. The fixing column 10 can be engaged with the hole groove 11 above the cylinder 4. By moving the fixing column 10 to the rear side, the fan can be fixed at the required height to ensure that the fan will not shake or shift during use. In addition to height adjustment, the fan can also be adjusted in angle. In the vertical direction, we can adjust the angle of the fan by rotating the cylinder 6. This cylinder 6 is connected to the main shaft of the fan. By rotating it, we can change the inclination angle of the fan. In the horizontal direction, the angle adjustment of the fan depends on The rotation of the hollow column 3 can change the horizontal angle of the fan so that it can blow air in different directions. The fan can be easily adjusted in multiple angles and heights by adjusting the height, horizontal and vertical directions. The roller 204 can be easily driven to turn by rotating the column 202. The roller 204 realizes the movement function of the fan by rolling on the concave plate 203. When the fan needs to be stopped, the pedal 206 is stepped on because the pedal 206 is connected to the L-shaped plate 205. When the pedal 206 is stepped on, the L-shaped plate 205 rotates and the plate at the bottom thereof contacts the roller 204. The principle of mechanics is utilized to increase the friction between the roller 204 and the L-shaped plate 205 to stop the roller 204 from rotating, thereby effectively preventing the fan from continuing to move.
