One end of the spring rod 212 is movably connected to the surface of the second limiting plate 210, and the end of the spring rod 212 is connected to the control The surface of the rod 115 is movable and snap-fitted.

In this embodiment, the turbid air in the workshop is discharged through the rotating motor 13 and the blade 14. During the discharge process, it is filtered by the filter 22 to avoid that the quality of the discharged air does not meet the standard and the workshop enterprise is punished. After the wind blows, the surface of the filter screen 22 will also be blocked by dust and other debris, affecting the exhaust efficiency. You only need to pull the spring rods 212 on both sides to allow the cleaning rod 27 to move, and then the surface of the filter screen 22 can be cleaned. To clean, pull the spring rods 212 on both sides to allow the cleaning rod 27 to start moving. At the same time, pull the handle on the second limit plate 210 to pull the second limit plate 210 out of the accommodating groove 29, and release the spring rod 212. The end of the spring rod 212 is pressed against the surface of the second limiting plate 210, so that it will not affect the cleaning of the cleaning rod 27. After that, the staff only need to move the cleaning rod 27 up and down repeatedly, and the cleaning brush head 28 will move the filter screen 22 up and down. The debris is swept off and falls into the dust box 24 for collection. It is only necessary to pull out the dust box 24 and dump it after each cleaning. After the cleaning is completed, the limit plate 210 is reset, and the spring rod 212 will move again. Fixing the cleaning rod 27 can achieve the effect of cleaning the filter 22, which can effectively prevent dust and other debris from clogging the mesh of the filter 22, affecting the exhaust effect, and the cleaned dust and debris will not Stay in the box 21.

Let’s talk about the working principle of the exhaust device used for workshop purification in detail.

As shown in Figure 1-6, by starting the rotating motor 13 to drive the blades 14 on the rotating head 12 to rotate, the turbid air in the workshop is discharged, thereby purifying the air in the workshop. During the discharge process, The filter 22 performs filtration to prevent the discharged air quality from not reaching the standard, which will cause the workshop company to be punished. After a long period of exhaust, the surface of the filter 22 will also be blocked by dust and other debris, affecting the exhaust efficiency. Pull the spring rods 212 on both sides to allow the cleaning rod 27 to move, and then the surface of the filter 22 can be cleaned. By pulling the spring rods 212 on both sides, the cleaning rod 27 can start to move, and at the same time, pull the limit plate 2 The handle on the second limit plate 210 pulls out the second limit plate 210 from the accommodation groove 29 and releases the spring rod 212. The end of the spring rod 212 presses against the surface of the second limit plate 210, thus not affecting the cleaning of the cleaning rod 27. After that, the staff only need to move the cleaning rod 27 up and down repeatedly. The cleaning brush head 28 will sweep off the debris on the filter screen 22 and fall into the dust box 24 for collection. It only needs to remove the dust after each cleaning. The dust box 24 can be pulled out and dumped. After cleaning, the second limit plate 210 is reset, and the spring rod 212 will fix the cleaning rod 27 again, so as to achieve the effect of cleaning the filter screen 22 and effectively avoid dust, etc. Debris blocks the mesh of the filter 22, affecting the exhaust effect, and the cleaned dust and debris will not stay in the box 21. After exhausting for a long time, the surface of the blade 14 will be eroded by dust, and Gradually adhere to its surface, which will easily cause pressure on the output of the rotating motor 13. At the same time, dust will spread everywhere when the blade 14 rotates. At this time, pulling the control rod 115 will make the blade 14 no longer fixed, and the blade 14 can be removed. Cleaning, at this time, by pulling the control rod 115, the extrusion plate 114 moves outward on the surface of the guide rail 110, and the spring 112 is extruded on the limiting plate 111. The movement of the extrusion plate 114 makes the fixed tooth block 113 The blade 14 is no longer engaged with the teeth 17 on one side of the fixed block 15, so that the blade 14 begins to loosen. At this time, the blade 14 is touched to the outside, so that the teeth 17 on the other side and the fixed teeth 18 fall off, thereby removing the blade 14. down to clean the floating dust on the surface of the blades 14 to ensure the exhaust efficiency of the blades 14.

The above generally describes the present utility model in detail, but on the basis of the present utility model, some modifications or improvements can be made, which is obvious to those of ordinary skill in the technical field. Therefore, any modification or improvement that does not deviate from the spirit of the present utility model is within the protection scope of the present utility model.
