The first chain 457 is ring-shaped and is wound around the first sprocket 453 and the third sprocket 455, whereby when the first sprocket 453 rotates, the first chain 457 is driven to rotate, thereby driving the third sprocket 455 to rotate, so that the first chain 457 reciprocally rotates in a cyclic manner. The second chain 458 is also annular and is wound around the second sprocket 454 and the fourth sprocket 456, so that when the second sprocket 454 rotates, the second chain 458 is driven to rotate, and the fourth sprocket 456 is driven to rotate, so that the second chain 458 reciprocally and circularly rotates.
Each first mesh 411 has opposite first and second ends, the first end of which is detachably connected to the first chain 457 and the second end of which is a free end, extending in the direction of the second end of each drive shaft. Thus, as first chain 457 rotates, first filter mechanism 41 may also rotate reciprocally and cyclically with first chain 457. Each second mesh 421 has opposite first and second ends, the second ends being detachably connected to the second chain 458, the first ends being free ends extending in the direction of the first ends of the respective drive shafts. Thus, as the second chain 458 rotates, the second filter mechanism 42 may also reciprocally rotate with the second chain 458.

The first mesh 411 and the second mesh 421 are adapted in shape and size, preferably have V-shaped cross sections, and are recessed toward the area surrounded by the second filter mechanism 42, so that the oil smoke can be better guided. Two sides (in the width direction) of each second mesh sheet 421 extend outwards for a certain distance and then bend towards the opposite sides to form two opposite guide rails 4211, and two sides of the first mesh sheet 411 are respectively placed in the guide rails 4211 so as to define the position of the first mesh sheet 411, so that the first mesh sheet 411 is guided to slide in the guide rails 4211; and the first mesh 411 and the second mesh 422 are mutually restricted, so that the first mesh 411 and the second mesh 421 are prevented from being tilted or tilted at the free ends, and the rotation of the first filter mechanism 41 and the second filter mechanism 42 is prevented from being influenced.
The push plate 459 includes two push plates, which are disposed on both sides of the first chain 457, respectively, and the two push plates 459 clamp the first chain 457 therebetween. Both ends of each push plate 459 are connected to the first and second transmission shafts 451 and 452, respectively, and each push plate 459 is movable with respect to the first and second transmission shafts 451 and 452 in a direction parallel to the axial directions of the two transmission shafts. After passing through one of the push plates 459, the output end of the first driving mechanism 44 passes through a blank in the middle of the first chain 457 and then extends to the other push plate 459, and the output end of the first driving mechanism 44 is respectively connected with the two push plates 459, so that the first driving mechanism 44 can drive the push plate 459 to move, and the push plate 459 drives the first chain 457, the first sprocket 453 and the third sprocket 455 to move. When first chain 457 moves, first filter mechanism 41 may move with it because first filter mechanism 41 is coupled to first chain 457.
The opening of the cleaning box 46 is inclined upward, and the inclination angle thereof may coincide with the panel 15. The cleaning box 46 also extends in the left-right direction, and the second transmission shaft 452 passes through the cleaning box 46, whereby the third sprocket 455 and the fourth sprocket 456 are located in the cleaning box 46. Brushes 48 are also respectively disposed in the cleaning box 46 at two sides of the second transmission shaft 452, and both brushes 48 are disposed on the rotation path of the first chain 457 (or the second chain 458). Thus, when the first filter mechanism 41 and the second filter mechanism 42 are partially rotated into the cleaning cartridge 46 during the reciprocating rotation, the brush 48 brushes the portion.
