The housing 110 has a substantially cylindrical shape extending in the up-down direction, for example, the housing 110 may have a square shape, a circular shape, or the like. In addition, the housing 110 may have a structure with both ends sealed. In an embodiment, the casing air inlet 111 is disposed on the periphery of the casing 110, and the opening at the top end of the casing 110 is the casing air outlet 112, so as to realize air inlet at one end and air outlet at the other end. Of course, in other embodiments, the housing air outlet 112 may be disposed on the peripheral side of the housing 110. It should be noted that the directional indications (such as up, down, left, right, front, and back … …) involved in the embodiments of the present invention are only used to explain the relative positional relationship between the components, the movement situation, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

Referring to fig. 3 to 5, the rotating body 120 is rotatably disposed in the purifying air duct 113, so that when water is sprayed on the rotating body 120, the rotating body 120 rotates to throw out the water, that is, the rotating body 120 rotates to throw out the water when rotating around its rotation axis, and the thrown water contacts with the air in the purifying air duct 113 to adsorb particles in the air, thereby purifying the air.

Specifically, in the present embodiment, the air purification module 100 further includes a rotation limiting member, which is disposed in the housing 110 and includes a first rotation limiting member 151 and a second rotation limiting member 152, and the first rotation limiting member 151 and the second rotation limiting member 152 are respectively rotatably connected to two ends of the rotation body 120. The rotation limiting member is used for providing radial and circumferential limiting for the rotating body 120, so that the rotating body 120 only moves circumferentially when rotating.
