In addition, by disposing the battery assembly 200 in the first dust collection chamber 121, the control board can be spaced apart from the battery assembly 200 by a large distance, thereby reducing electromagnetic interference.
As shown in fig. 1 and 4, in one embodiment, the cleaning apparatus further includes a hood 310, the hood 310 is connected to the separating mechanism 300, the suction member 400 is disposed in the hood 310, and the hood 310 is configured to separate the suction member 400 from the first dust collecting chamber 121, so as to prevent dirt in the first dust collecting chamber 121 from being sucked into the suction fan 400.
Specifically, the hood 310 is formed with a receiving chamber for receiving the air draft member 400, the separation mechanism 300 includes a plurality of cyclone cones, the cyclone cones enclose an annular structure, and dust outlet ends 301 of the cyclone cones extend into the first dust collecting chamber 121, the hood 310 is disposed in the annular structure and connected with at least one cyclone cone, the air draft member 400 is disposed in the hood 310 and coaxially disposed with the battery assembly 200, and the hood 310 separates the first dust collecting chamber 121 from the receiving chamber.

When the outside air enters the second dust collecting chamber 111 through the air inlet 112, the outside air passes through the filter member 700, the filter member 700 filters out large-particle dirt substances in the air, and the air is discharged into the second dust collecting chamber 111, and the air with the remaining small-particle dirt substances enters the separating mechanism 300 through the air inlet end 302 of the separating mechanism 300 and is separated again, so that the cleaning effect of the whole cleaning device is improved.
Further, the filter member 700 is a filter screen, the filter screen is sleeved outside the first dust collecting member 120, and a first ventilation channel 701 is formed between the filter screen and the first dust collecting member 120, and the first ventilation channel 701 is communicated with the air inlet end 302 of the separating mechanism 300. The filter screen and the inner wall of the second dust collecting member 110 define a cyclone separator, and when air enters the second dust collecting chamber 111 through the air inlet 112, part of the air rotates along the inner wall of the second dust collecting member 110 to be primarily separated, and then enters the first ventilation channel 701 through the filter screen to be filtered by the filter screen. Since the first ventilation passage 701 is formed between the filter mesh and the first dust collection member 120, the air flowing in the first ventilation passage 701 can also radiate heat from the battery assembly 200 disposed in the first dust collection chamber 121, thereby cooling the battery assembly 200.
Still further, the cleaning apparatus 10 further includes a first sealing member 800, one end of the first sealing member 800 is connected to the filter member 700, the other end is connected to the inner wall of the second dust collecting member 110, a second ventilation passage 801 communicating with the first ventilation passage 701 is formed between the first sealing member 800 and the first dust collecting member, and the second ventilation passage 801 communicates with the air inlet end of the separation mechanism 300. In this way, the air flowing through the first ventilation channel 701 enters the second ventilation channel 801, and then enters the separating mechanism 300 through the air inlet end of the separating mechanism 300 to perform air-dust separation, so that the air coming out of the first ventilation channel 701 can be prevented from penetrating into the second dust collecting cavity 111 again.
Optionally, the first sealing member 800 is a sealing ring, the first sealing member 800 is sleeved outside the first dust collecting member 120, one end of the first sealing member 800 is connected with the filtering member 700, and the other end is connected with the inner wall of the second dust collecting member 110.

In addition, since the post-filter 600, the air suction member 400, and the battery assembly 200 are coaxially disposed, the space occupied by the cleaning device in the direction perpendicular to the axial direction of the air suction member 400 can be reduced, so that the cleaning device is more miniaturized.
An embodiment also relates to a vacuum cleaner comprising a cleaning apparatus 10 as described above.
The cleaner includes the cleaning device 10, and in the cleaning device 10, the battery assembly 200 is disposed in the first dust collection chamber 121 by using the space of the first dust collection chamber 121 of the first dust collection member 120, so that the space utilization rate of the first dust collection chamber 121 is improved. And by disposing the battery assembly 200 in the first dust collection chamber 121, the occupation space of the cleaning apparatus 10 can be reduced as a whole, as compared with disposing a member for mounting the battery assembly 200 on the cleaning apparatus 10.
