That is, the air introduced into the air treatment assembly 100 separates the ash having a high specific gravity and the ash having a large size in the first dust collecting chamber 10 by using the gravity, and then the fine ash is secondarily cyclone-separated by the cyclone 2. It should be noted that the separation principle of separating dust by using the cyclone separation technique is the prior art, and will not be described in detail here.

It should be noted that, in order to ensure the dust suction requirement of the cleaning apparatus 1000, the dust inlet 202A of the cleaning apparatus 1000 is generally in a long strip shape. However, since the separation inlet 201B of the cyclone separator 2 is generally rectangular, if the separation inlet 201B of the cyclone separator 2 is directly connected to the clean ash inlet 202A, the clean ash inlet 202A connected thereto is very small, which cannot meet the ash suction requirement, and the dust-collecting performance of the cleaning apparatus 1000 is reduced.

While the dusting performance of the cleaning device 1000 can be ensured.

In some embodiments of the present invention, the separation inlet 201B is located at the top of the separation chamber 20 and the first dust outlet 202B is located at the bottom of the separation chamber 20. Thereby can carry out the eminence through separation import 201B and advance grey, then the air current spiral downstream under the action of gravity, throw away the dust at the first dust outlet 202B of cyclone 2 bottom, can guarantee that the interior heavy specific gravity ash deposition of first dust collecting cavity 10 is in first dust collecting cavity 10, and the heavy specific gravity ash is difficult to be inhaled in separating cavity 20, and stifled grey phenomenon can not appear in cyclone 2, can not appear dust blocking phenomenon on the bottom plate in separating cavity 20.

Specifically, the second dust collecting chamber 11 includes bottom walls having different heights, and adjacent two bottom walls define a corner 110. Thereby making the structure of the second dust collecting chamber 11 simple. In some specific examples of the present invention, as shown in fig. 5, the second dust collecting chamber 11 includes a first bottom wall 111, a second bottom wall 112, and a connecting wall 113, the second bottom wall 112 is located above the first bottom wall 111, upper and lower ends of the connecting wall 113 are connected to the first bottom wall 111 and the second bottom wall 112, respectively, and the first bottom wall 111, the second bottom wall 112, and the connecting wall 113 are formed in a stepped shape to define the turn portion 110.
