Optionally, the fixed structure further includes a stopper 16, where the moving handle 3223 abuts against the stopper 16 to limit the second limit position of the moving member 32. The stopper 16 is located the up end of bulge, and is located the one side that first draw-in groove 13 is close to the inner wall of box 1, and stopper 16 is connected with the up end of the inner wall of box 1 and bulge. When the bottom of the moving handle 3223 of the moving member 32 is in contact with the upper surface of the stopper 16 and the connection between the upper and lower parts of the moving member 32 is in contact with the hook 3123 of the mounting member 31 during the installation of the dust bag 2, it is indicated that the moving member 32 is moved in place, and the through hole 321 completely connects the mounting hole 3111 and the dust hole 11.

In the dust box provided in this embodiment, when the dust bag 2 is mounted, the limiting plate 3122 is set towards the protruding portion, the elastic buckles 3121 on two sides of the upper end of the mounting member 31 are guided to compress from the guiding surface 151, slide into the second clamping groove 152 to be clamped with the second clamping groove 152, and simultaneously two sides of the lower end of the mounting member 31 are respectively inserted into the two guiding grooves 14, so as to realize the fixation of the mounting member 31. Then install moving member 32 again, moving member 32's first side sets up towards the bulge, and insert in the clearance between mounting member 31 and the bulge, moving member 32 runs through the second spout on the mounting member 31 earlier and reenters first spout 12, moving member 32's lower part gets into in the first spout 12, the junction of moving member 32 upper portion and lower part cooperates the joint with trip 3123 on the mounting member 31, and when moving handle 3223 and stopper 16 butt, moving member 32 moves to the second extreme position, trip 3123 on the mounting member 31 and stopper 16 on the bulge realize the lower spacing of moving member 32 jointly, in order to guarantee moving member 32 position's accuracy, thereby make the via hole 321 on the moving member 32 communicate mounting hole 3111 and dust hole 11 totally, guarantee the smoothness when rubbish such as dust gets into dust bag 2. The first buckle 3221 on the upper portion of the moving member 32 is engaged with the first clamping groove 13 on the upper end face of the protruding portion, and the second buckle 3231 is engaged with the top end of the mounting member 31, at this time, when the cleaning robot works normally, dust and other garbage outside the box 1 can enter the inner space of the dust bag 2 through the dust guide hole 11, the through hole 321 and the mounting hole 3111.

When the dust bag 2 is replaced, the moving member 32 is lifted up by the moving handle 3223, the moving member 32 moves up, the first limiting protrusion 3232 of the second side 323 of the moving member 32 is clamped with the first limiting groove 3112 at the bottom end of the mounting plate 311, meanwhile, the second limiting protrusion 3222 of the first side 322 of the moving member 32 is abutted with the bottom of the limiting plate 3122 located at the lowest position of the connecting plate 312, at this time, the first limiting groove 3112 at the bottom end of the mounting plate 311 and the bottom of the limiting plate 3122 located at the lowest position of the connecting plate 312 jointly provide the upper limit of the moving member 32 moving in the mounting plate 31, so that the clamping and fixing of the moving member 32 and the mounting plate 31 are realized, the moving member 32 moves to the first limiting position, at this time, the through hole 321 on the moving member 32 completely seals the mounting hole 3111 and the dust guiding hole 11, and dust in the dust bag 2 cannot fly out through the mounting hole 3111 in the process of moving out the dust bag 2. Then, the moving handle 3223 continues to drive the moving member 32 to move upwards, at this time, the mounting member 31 moves upwards along with the moving member 32, the elastic buckles 3121 on two sides of the upper portion of the mounting member 31 are separated from the second clamping groove 152 under the action of upward tension and gradually move upwards under the compression of the guide surface 151, and when the elastic buckles 3121 are separated from the guide surface 151 and are abutted, the mounting member 31 and the dust bag 2 are removed from the box 1 together through the moving member 32, so that the dust bag 2 is replaced.

The embodiment also provides a cleaning robot, which comprises a cleaning main body and the dust box arranged on the cleaning main body. The cleaning robot that this embodiment provided, use foretell dust box, remove piece 32 and mounting 31 and fixed knot construct be connected, under the circumstances that guarantee to remove piece 32 can normally remove, reduce the deformation space of removing piece 32 between mounting 31 and fixed knot construct as far as possible for remove piece 32 difficult emergence deformation under the negative pressure environment, dust can not fly out from dust bag 2 when having guaranteed to change dust bag 2, and dust bag 2 is more easy to change, has improved user's use experience.

The foregoing is merely exemplary of the present invention, and those skilled in the art should not be considered as limiting the invention, since modifications may be made in the specific embodiments and application scope of the invention in light of the teachings of the present invention.
