Specifically, with the dust box in the present disclosure, only after the user puts the filter screen assembly into the accommodation structure in the dust box body, the dust box cover can be sealed on the top of the accommodation space and snapped into place. On the dust box body. When the user misses the filter screen assembly, the dust box cover cannot be fastened on the dust box body, thereby reminding the user to avoid missing the filter screen assembly.

Optional embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings.

FIG. 1 is a schematic structural diagram of a dust box provided by some embodiments of the present disclosure, FIG. 2 is a schematic structural diagram of a dust box cover of the dust box in FIG. 1 , and FIG. 3 is a structural schematic diagram of a dust box body of the dust box in FIG. 1 . As shown in FIGS. 1-3 , the dust box 100 includes a dust box body 10 and a dust box cover 20 . The dust box body 10 includes a bottom wall 15 and at least one side wall arranged around the edge of the bottom wall 10, and the side wall extends away from the bottom wall 15 away from the bottom wall 15, and the bottom wall 15 and the side wall form a circle. The accommodating space 30 is configured to accommodate garbage and a filter assembly.

The dust box cover 20 is pivotally connected to the first side wall 11 of the dust box body 10, and is configured to cover the top of the accommodating space 30. The orthographic projection in the plane of the dust box body 10 is roughly rectangular. The first side wall 11 of the dust box body 10 is, for example, a short side wall of the dust box body 10. The short side wall herein represents the corresponding part of the cuboid. The side walls of the short sides of the rectangular projection, correspondingly, the long side walls herein refer to the side walls of the cuboid corresponding to the long sides of the rectangular projection. The dust box cover 20 can rotate around a pivot axis relative to the first side wall 11 of the dust box body 10 , so that the dust box 100 can be switched between an open state and a closed state.

When the dust box cover 20 completely covers the top of the accommodating space and engages with the dust box body 10 through a buckle structure, the dust box 100 is in a closed state. When the dust box cover 20 is rotated so that at least a part of the accommodating space 30 is exposed, the dust box 100 is in an open state. The dust box 100 can be switched between the closed state and the open state, so as to facilitate the user to clean up the garbage in the dust box 100, clean or replace the filter screen structure and other operations.

The second side wall 12 of the dust box 10 has an elastic member 40 elastically pivotally connected to the second side wall 12 , wherein the elastic member 40 surrounds the second side wall 12 along the first direction. The first axis A1 along which X extends is rotatable, the first direction X is parallel to the bottom wall 15 , and the first direction X is also parallel to the extension direction of the second side wall 12 .

The dust box cover 20 has a protrusion 21 configured to cooperate with the elastic sheet assembly 40 when the dust box cover 20 is covering the top of the accommodating space 30 .
