Abstract:
An air purification device (10) comprises a housing (100), a fan (300), and filters (200). The housing (100) is provided with an air inlet (110), a front air outlet (120), and a side air outlet (130). The fan (300) comprises a fan air outlet (310), and the fan air outlet (310) directly faces to the front air outlet (120). There are multiple filters (200). A filter (200) is disposed at each of a second position between the fan (300) and the front air outlet (120) and a third position between the fan (300) and the side air outlet (130). When an airflow extracted from the air inlet (110) is directly blown from the fan air outlet (310) to the front air outlet (120) and passes through the filter (200) placed at the second position, the flowing direction of the airflow does not need to be changed, and the airflow is discharged from the front air outlet (120). When the airflow is conveyed from the fan air outlet (310) to the side air outlet (130) and passes through the filter (200) placed at the third position, the airflow direction is changed and the airflow is discharged from the side air outlet (130).
