More specifically, as shown in fig. 1, the garbage storage box 1 has an upper, middle and lower tee opening structure, and the middle opening is tightly combined with the cyclone blades 7; the lower end opening (namely a garbage inlet) is tightly combined with a garbage feeding hole arranged on the chassis 2, and a flow blocking brush can be arranged at the lower end opening of the garbage storage box 8 in order to prevent the cleaned and collected garbage from spilling out of the garbage storage box 8.

Further, as shown in fig. 8, the flow blocking brush 13 includes a flow blocking bristle bundle 131, a flow blocking bristle bundle cylinder 132, and a flow blocking bristle bundle cylinder driving gear 133. Wherein, the flow blocking bristle bundle roller 132 can be arranged on the chassis 2 in a rolling way; the flow blocking bristle bundle roller driving gear 134 is coaxially and fixedly connected with the flow blocking bristle bundle roller 132; the flow blocking bristle bundle 131 is arranged on the outer peripheral wall of the flow blocking bristle bundle roller 132 along the direction of the spiral line; the flow blocking bristle bundle roller driving gear 134 is in transmission connection with the bristle bundle roller driving gear 94 of the cleaning brush; the flow blocking bristle bundles 131 are in intersecting engagement with the cleaning brush bristle bundles 91.

Furthermore, the beneficial effects of the embodiment are as follows: as shown in fig. 1 and fig. 9, when the manual garbage sweeper travels along the sweeping direction (i.e. when the traveling wheel 10 rotates clockwise), the sweeping brush 9 rotates clockwise to sweep the garbage such as paper scraps, ash, etc. on the ground toward the lower opening (i.e. garbage inlet) of the garbage storage box 8, at this time, the flow blocking brush 13 rotates counterclockwise, and under the intersecting and meshing action of the flow blocking brush bristle bundles 131 and the sweeping brush bristle bundles 91, the garbage such as paper scraps, ash, etc. on the ground can be further swept toward the lower opening (i.e. garbage inlet) of the garbage storage box 8, thereby increasing the sweeping efficiency.

More specifically, as shown in fig. 10 and 11, the sealing cap 12 is composed of a cap cover 121 and a cap sealing ring 122, and the cap sealing ring 122 is disposed on the lower surface of the cap cover 121 to further seal the bin 8. In order to facilitate the cleaning of garbage, the garbage storage box 8 is preferably a split structure that can be separated from the sealed housing 1 and the chassis 2.
