Further, referring to fig. 1 to 7, the first circulation cavity 114 and the second circulation cavity 115 are stacked. So that the first circulation chamber 114 and the second circulation chamber 115 are stacked, the first circulation chamber 114 and the second circulation chamber 115 may be stacked up and down, left and right, or front and back. In order to reduce the height of the air treatment device 100, the first circulation chamber 114 and the second circulation chamber 115 are optionally stacked in the horizontal direction. By stacking the first circulation chamber 114 and the second circulation chamber 115, the structure of the air treatment device 100 is more compact, and the volume of the air treatment device 100 is reduced.

In this embodiment, the first installation cavity 114b and the second installation cavity 115b may be isolated from each other by a partition plate, so that the first installation cavity 114b and the second installation cavity 115b are prevented from blowing wind. One end of the first channel 114a is communicated with the air inlet end of the first mounting cavity 114b, and the other end is communicated with the fresh air inlet 111, and the rest of the first channel 114a can be separated from the first mounting cavity 114b through the partition plate, so that the air volume is more concentrated, and the fresh air inlet volume and the fresh air inlet efficiency are improved. One end of the second channel 115a is communicated with the air inlet end of the second mounting cavity 115b, and the other end is communicated with the air return port 113, so that the rest parts of the air inlet ends of the second channel 115a and the second mounting cavity 115b can be separated by the partition plate, thereby enabling the air quantity to be more concentrated, and improving the air exhaust air quantity and the indoor air exhaust efficiency. Through making first passageway 114a, first installation cavity 114b, second installation cavity 115b, second passageway 115a range upon range of setting in proper order, when guaranteeing new trend air intake, new trend air inlet efficiency, the amount of wind of airing exhaust, the efficiency of airing exhaust for whole air treatment device 100's overall arrangement is more reasonable, the structure is compacter.
