摘要： The present application is applicable to the field of household appliances, and discloses a fan head assembly and a fan. The fan head assembly includes an air outlet base; an air inlet base provided at one side of the air outlet base; and a rotation-swing mechanism, configured to drive the air outlet base to rotation-swing relative to the air inlet base. The rotation-swing mechanism includes a rotation-swing drive motor, mounted on the air inlet base; and a rotation-swing transmission pair, transmissively connecting the rotation-swing drive motor and the air outlet base. In the present application, the air outlet base is able to rotationally swing relative to the air inlet base, which breaks the conventional design idea that the air outlet base and the air inlet base in the existing fan are relatively fixed. Since the air outlet base is three-dimensionally swinging relative to the air inlet base, the product may works in a cool way, which solves the problem of serious homogeneity and no different selling points of existing fan products. At the same time, it effectively expands the air supply area and enabless the rotational output of the wind direction, so that the output wind feeling is softer and more natural.

The elevation mechanism is connected to the wet pad and is configured to drive the wet pad to move, so that the humidification module can be switched between a humidifying state and a non-humidifying state. In the humidifying state, part of the wet pad is immersed into the water in the wet pad water tank, and in the non-humidifying state, the wet pad is lifted above the water level of the wet pad water tank. The purification and humidification module further includes a purification module with an annular shape and at least partially sleeved outside a part of the wet pad extending out of the wet pad water tank. The humidification and purification apparatus improves the efficiency of purification and humidification, reduces operation noise, avoids the wet pad from being immersed in water for a long time, and improves service performance of the humidification and purification apparatus.
