Specifically, in the present embodiment, there are four limit plates 41, four rotating screws 44 and four driving motors 42, and each limit plate 41 corresponds to one rotating screw 44 and one driving motor 42.

[0025] The cleaning assembly 30 includes a cleaning plate 31 disposed on the limiting plate 41, a plurality of dust collecting plates 32 disposed on the frame 10, and a fan 33 disposed on the dust collecting plates 32. The cleaning plate 31 is provided with cleaning bristles 311 facing the frame 10, and the cleaning bristles 311 are in contact with the top surface of the frame 10.

[0026] A plurality of ash collecting plates 32 are all disposed toward the limiting plate 41, and a plurality of ash collecting plates 32 are all provided with ash collecting grooves 321. Specifically, the ash collecting grooves 321 are disposed on one side of the ash collecting plate 32 close to the vibration-damping pad 50. In this embodiment, four ash collecting plates 32 are provided, and the four ash collecting plates 32 are disposed in pairs with respect to the vibration-damping pad 50, and adjacent ash collecting plates 32 are in contact with each other, so that the waste residue on the frame 10 is collected on the ash collecting plates 32.
