To facilitate the user pulling the air treatment module 120, optionally, the opening 115 of the mounting location 113a is disposed toward the front side of the air treatment device 100. In order to facilitate the drawing of the air treatment module 120, a sliding groove structure may be disposed on one of the air treatment module 120 and the inner wall surface of the housing 110, and a sliding rail structure may be disposed on the other, so that the air treatment module 120 and the housing 110 are connected in a sliding groove sliding rail manner. When the air treatment module 120 is inserted into the mounting location 113a from the opening 115 such that the rear wall surface of the air treatment module 120 abuts the wall surface of the mounting location 113a opposite the opening 115, the mounting of the air treatment module 120 in place is indicated. The first conductive member 114 is disposed on the wall surface of the mounting position 113a opposite to the opening 115, so that the second conductive member 121 of the air treatment module 120 is electrically conducted with the first conductive member 114 of the housing 110 only when the air treatment module 120 is mounted in place, thereby avoiding the risk of electric leakage caused by electric conduction when the air treatment module 120 is not mounted in place.

Specifically, the second elastic member 40 may be fixed to an inner wall surface of the air duct 113, or may be fixed to an outer wall surface of the air duct 113. The nib 50 may be in particular spherical or roller-shaped.
