Herein, the air intake structure may be used in a side air intake position of an air processing device such as an air conditioner, a humidifier, an air purifier, and a dehumidifier, and is not limited herein. This disclosed embodiment uses air condensing units as an example, also can be used for other air treatment equipment that have the side air inlet position with the air inlet structure in other embodiments of this application to avoid the dust in the environment of air treatment equipment place to get into in the air treatment equipment along with the air inlet.

In general, the side air intake position of the air treatment device may refer to a portion of the housing of the air treatment device, which is disposed in a vertical direction. The air inlet structure is arranged at the side air inlet position, and the arrangement direction of the panel 110 is the vertical direction.

Optionally, the hollow portion may include an opening disposed on the surface of the panel 110 in the vertical direction, the opening may be in the shape of a strip, and the width of the strip-shaped opening may be greater than the height of the strip-shaped opening. Wherein, the width can be the inner diameter of the opening along the horizontal direction; the height may be an inner diameter of the opening extending in a vertical direction.
