The vacuum cleaner further comprises a third restoring member 233, the third restoring member 233 is preferably a spring, and the third restoring member 233 is connected to the limiting member 23. Referring specifically to fig. 11-14, when the user does not install the dust bag 14, the blocking plate 232 continuously presses the movable member 21 to make the movable member 21 have a tendency to move into the accommodating portion 165, and the first elastic member 24 is in a compressed state. Referring to fig. 15-18, when the dust bag plate 15 moves to the installation position by the operation of the user, the dust bag plate 15 pushes the limiting member 23 to move along the installation direction of the dust bag plate 15, at this time, the third restoring member 233 is compressed, the blocking plate 232 is separated from the movable member 21, the first elastic member 24 pushes the movable member 21 to move out of the accommodating portion 165, so that the connecting portion 211 is connected to the opening 151 of the dust bag plate 15, and the knocking portion 212 knocks the blocking member 22 to generate a knocking sound, so that the user can know that the dust bag 14 is installed correctly. Referring to fig. 19 to 20, the bracket 16 is rotated from the second position to the first position by a user operation, at this time, the connecting part 114 pushes the connecting part 211 to be separated from the opening 151 of the dust bag plate 15, the connecting part 114 is connected to the opening 151 of the dust bag plate 15, and meanwhile, the first hook 161 is connected to the second hook 131 by a snap, so that the operating part 13 is in the first state, and the dust bag 14 is stably mounted on the vacuum cleaner. Referring to fig. 11 to 14 again, when a user applies an external force to the operating element 13 to rotate the operating element 13 from the first state to the second state, at this time, the first hook 161 is disengaged from the second hook 131, the bracket 16 moves from the first position to the second position, and the connecting member 114 is separated from the opening 151 of the dust bag plate 15, so that the dust bag plate 15 is separated from the bracket 16 due to gravity, the third restoring member 233 restores the original position, and pushes the limiting member 23 to move in the direction opposite to the installation direction of the dust bag plate 15, so that the blocking plate 232 cooperates with the movable member 21 again to keep the movable member 21 in the accommodating portion 165.

In the second embodiment of the present invention, the user locks the bracket 16 to the housing 11 and then mounts the dust bag panel 15 to the bracket 16, whereby the dust bag panel 15 can be stably mounted to the cleaner. In this embodiment, the locking mechanism is disposed on the housing 11, and the locking mechanism includes a connecting member 114, different from the first embodiment, the connecting member 114 of this embodiment is movably disposed on the housing, and when the dust bag panel 15 is located at the installation position, the connecting member 114 is connected to the dust bag panel 15. Specifically, the connecting member 114 is configured to move between an extended position and a retracted position, and in this embodiment, an elastic unit (not shown) is further disposed between the connecting member 114 and the housing 11, and when the connecting member 114 is located at the retracted position, the elastic unit is compressed, so that the connecting member 114 has a movement tendency to return to the extended position. When a user needs to mount the dust bag 14, the user needs to rotate the bracket 16 to the first position along the first direction m, and then mount the dust bag plate 15 to the bracket 16 from the lower side of the bracket 16. Specifically, when the dust bag panel 15 is separated from the bracket 16, the connecting member 14 is in the extended position, and during the movement of the dust bag panel 15 to the installation position by the user operation, the dust bag panel 15 pushes the connecting member 14 to move to the retracted position, and the elastic unit is compressed; when the dust bag panel 15 moves to the installation position, the connection member 14 returns to the extended position and is connected to the opening portion 151 of the dust bag panel 15, whereby the dust bag panel 15 is stably installed to the cleaner.
