Rotate the reciprocating lead screw 10 of the replaced T-shaped frame 3. The moving plate 12 makes a reciprocating motion in the vertical direction by using the reciprocating lead screw 10 in cooperation with the sliding rod 9. The moving plate 12 drives the cleaning brush 11 to move, so as to clean one side of the filter screen 4. The device quickly solves the problem that soot accumulates on the filter screen 4, thereby affecting the filtering effect, and at the same time saves production costs, is beneficial to cleaning the filter screen 4, and is beneficial to actual application and operation.

[0028] Specifically, the fixing components include a pull rod 8, a return spring 13, a limit block 15, a through groove 14, and a clamping groove 16. The through grooves 14 are all opened at the four corners inside the smoke exhaust pipe 1. The limit blocks 15 are all slidably connected to the inner walls of the through grooves 14. The pull rods 8 are all fixedly connected to the interiors of the limit blocks 15. The clamping grooves 16 are opened at the four corners outside the T-shaped groove 2. One end of the pull rod 8 extends into the smoke exhaust pipe 1 and is used in cooperation with the corresponding clamping groove 16.

[0037] Through the above technical solution, using stainless steel plates as materials is beneficial to extending the service life of the smoke exhaust pipe 1 and increasing the corrosion resistance of the device. The fact that the length and width of the T-shaped groove 2 are both greater than the length and width of the inner wall of the smoke exhaust pipe 1 is beneficial to placing the T-shaped frame 3 and thus facilitating smoke exhaust.

[0038] In use, the device is installed at a specified position. The T-shaped frame 3 is placed in the T-shaped groove 2 and pressed. When the T-shaped frame 3 moves downward, the slope on one side of the pull rod 8 cooperates with its bottom to make it move outward. When the T-shaped frame 3 moves to a suitable position, the return spring 13 cooperates with the limit block 15 to reset the pull rod 8. The pull rod 8 cooperates with the card slot 16 to fix the T-shaped frame 3 of the device inside the T-shaped groove 2, and the sealing gasket 5 is used for sealing. Thus, the soot is filtered at the filter screen 4. When there is more dust on the filter screen 4, the pull rod 8 is pulled to separate one end thereof from the card slot 16, and the filter screen 4 is taken out for replacement. The rotary handle 7 is used to drive the reciprocating lead screw 10 to rotate. The reciprocating lead screw 10 cooperates with the slide rod 9 to make the moving plate 12 perform reciprocating motion in the vertical direction. The moving plate 12 drives the cleaning brush 11 to move, so as to clean one side of the filter screen 4. The device can quickly solve the problem that the soot accumulates on the filter screen 4, thus affecting the filtering effect. At the same time, it saves the production cost, is beneficial to cleaning the filter screen 4, and is beneficial to practical application and operation.
