Furthermore, the dust suction assembly 50 comprises a shell 51, and at least two connecting structures 53 formed on an outer surface of the shell 51. The shell 51 is optionally assembled with the supporting ring 30, when the shell 51 is connected with the supporting ring 30, the shell 51 is positioned above the dust collection barrel 10; when the shell 51 is separated from the supporting ring 30, the shell 51 is removed from the dust collection barrel 10. The at least two connecting structures 53 correspond to the at least two connectors 13, and the at least two connecting structures 53 are provided for assembling with the at least two connectors 13 to restrict the dust suction assembly 50 from separating from the dust collection barrel 10 when in use. Further, the shell 51 has at least one shell outer diameter 511, and the at least one shell outer diameter 511 is smaller than the opening diameter 121 but larger than the ring inner diameter 31. In one embodiment, when the shell outer diameter 511 is a constant, it means that the shell 51 has no change in outer diameter. In another embodiment, when a plurality of shell outer diameters 511 are provided, it means that the shell 51 has changes in outer diameter, and each of the plurality of shell outer diameters 511 is smaller than the opening diameter 121, but larger than the ring inner diameter 31.
