Further, the hot water can effectively clean the smoke filter 17 inside the cleaning shell 2.

[0035] It is worth noting that see Figures 1 to 4 A first spring 44 is provided on the side where the first wedge block 43 is connected to the slide rod 41, and a second spring 46 is provided on the side where the second wedge block 45 is connected to the second drive rod 31. The first spring 44 and the second spring 46 are respectively sleeved on the outside of the slide rod 41 and the second drive rod 31.

[0036] When the servo motor 25 drives the smoke filter 17 on one side of the fixed frame 16 to move out of the cleaning shell 2, the elastic force of the first spring 44 on one side of the first wedge block 43 can push the first wedge block 43 to move in the opposite direction and reset in the adjustment groove 42, and the elastic force of the second spring 46 on the bottom side of the second wedge block 45 can push the second wedge block 45 to move upward, thereby pushing the brush 3 at the bottom end of the second driving rod 31 to move upward, avoiding the brush 3 from interfering with the movement of the smoke filter 17. At the same time, the second driving rod 31 can drive the second driving bevel gear 32 to separate from the second connecting bevel gear 35, and automatically control the brush 3 to stop rotating.
