When the cleaning member 11 rotates around the second transmission member 32, the first transmission member 31 is driven to rotate around the second transmission member 32 as a rotation axis, and meanwhile, when the first transmission member 31 rotates around the second transmission member 32, the second transmission member 32 can act on the first transmission member 31, so that the first transmission member 31 rotates around the target rotation axis, and when the first transmission member 31 is in a cylindrical arrangement, the target rotation axis is the central axis of the first transmission member 31.
Further, in combination with fig. 9 and fig. 10, various specific embodiments of the abutting portions of the first transmission member 31 and the second transmission member 32 are provided, in an embodiment, the first transmission member 31 includes a mating portion 3111, the second transmission member 32 includes a guiding portion 3211, the guiding portion 3211 and the mating portion 3111 interact together to form the abutting portion, where the mating portion 3111 includes a plurality of guiding protrusions disposed along a circumferential direction of the first transmission member 31, the guiding portion 3211 includes a spiral segment 3211a disposed along an axial direction of the second transmission member 32, the spiral segment 3211a extends along the axial direction of the first transmission member 31, and when the cleaning member 11 rotates, the first transmission member 31 is driven to rotate around the second transmission member 32, so that at least one guiding protrusion may be clamped in a groove of the spiral segment 3211a, and when the guiding protrusion moves along the spiral groove, the spiral groove may apply a force on the guiding protrusion along the axial direction of the second transmission member 32 due to the first transmission member 31 being in a static state, so that the second transmission member 32 rotates around its central axis.
