A connecting seat 9 is fixedly installed at one end of the plurality of connecting sliding rods 8. A cleaning brush 10 that fits the filter screen 3 is detachably installed on the side of the connecting seat 9 through a convenient disassembly assembly component. An elastic extrusion element for applying a thrust to the connecting seat 9 is connected to the connecting plate 7. The elastic extrusion element includes an extrusion spring 11 which is sleeved on the connecting sliding rod 8, and both ends of the extrusion spring 11 are respectively fixedly installed on the sides of the connecting plate 7 and the connecting seat 9 that are close to each other.

[0025] By means of the above structure, when exhaust gas enters the air intake pipe, the pneumatic fan blades 6 will be blown to rotate, and the rotation of the pneumatic fan blades 6 will drive the driving shaft 5 to rotate. The driving shaft 5 will drive the cleaning brush 10 to rotate through the connecting plate 7, the connecting slide rod 8 and the connecting seat 9, so as to automatically clean the filter 3. Under the elastic force of the extrusion spring 11, the cleaning brush 10 will be squeezed and pushed to keep close to the filter 3 for cleaning. The cleaning effect is better, and the situation that the filter 3 is always blocked by dust and waste particles can be effectively reduced. Frequent manual cleaning is no longer required, which greatly reduces the workload of the staff. The structure is simple, the use is convenient, and the practicality is good.

[0026] In this embodiment, the other ends of the plurality of connecting slide bars 8 are fixedly mounted with anti-disengagement blocks 12. The advantage of such a setting is that, through the setting of the anti-disengagement blocks 12, the connecting slide bars 8 can be limited and blocked to prevent the connecting slide bars 8 from being separated from the connecting plate 7.

[0028] refer to Figure 2 and Figure 3 As shown, the convenient disassembly and assembly component includes two mounting plates 13 fixedly mounted on the side of the cleaning brush 10, a linkage cavity is provided in the connecting seat 9, and the top and bottom of the connecting seat 9 are provided with rod sliding holes connected to the linkage cavity, and rectangular rods 16 are slidably installed in the two rod sliding holes, and two fixing plates 14 are fixedly mounted on the side inner wall of the linkage cavity, and the tops of the two fixing plates 14 are provided with screw rotating holes, and two-way screws 15 are installed in the two screw rotating holes for common rotation, and the two rectangular rods 16 are respectively threadedly sleeved on the two ends of the two-way screw rod 15, and the tops of the two mounting plates 13 are provided with rectangular plug holes, and the ends of the two rectangular plug rods 16 away from each other respectively pass through the two rectangular plug holes, and a control rotating hole is provided on the side inner wall of the linkage cavity, and a control rotating rod 17 is rotatably installed in the control rotating hole, one end of the control rotating rod 17 is connected to a synchronous transmission unit for making the two-way screw rod 15 rotate synchronously, and the other end of the control rotating rod 17 is fixedly installed with a control knob 18. The advantage of such a configuration is that when the control knob 18 is turned, the control rotating rod 17 will be driven to rotate, and the rotation of the control rotating rod 17 will drive the two-way screw rod 15 to rotate synchronously through the synchronous transmission unit, and the rotation of the two-way screw rod 15 will drive the two rectangular plug rods 16 to move toward or away from each other. When the two rectangular plug rods 16 are moved toward each other and moved out of the two rectangular plug holes at the same time, the mounting plate 13 and the cleaning brush 10 can be loosened. When the two rectangular plug rods 16 are moved away from each other and inserted into the two rectangular plug holes at the same time, the mounting plate 13 and the cleaning brush 10 can be fixed, thereby achieving the purpose of facilitating the disassembly, assembly and replacement of the cleaning brush 10, and having better practicality.

[0029] In this embodiment, the synchronous transmission unit includes a first bevel gear 19 fixedly mounted on the end of the control rotating rod 17, and a second bevel gear 20 meshing with the first bevel gear 19 is fixedly sleeved on the bidirectional screw rod 15. The advantage of this arrangement is that when the control rotating rod 17 rotates, the first bevel gear 19 is driven to rotate, and the rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate together, thereby driving the bidirectional screw rod 15 to rotate synchronously, thereby achieving the effect of synchronous transmission.
