Abstract:
An air purifier, comprising a housing (100). A purification assembly for purifying air and a fan (200) for driving a gas to flow are provided in an inner cavity of the housing (100); the housing (100) is provided with an air inlet (121) and an air outlet (111), and the purification assembly and the fan (200) are located between the air inlet (121) and the air outlet (111); a driving motor (300) is further provided in the inner cavity of the housing (100), and the driving motor (300) is provided on a side portion of the fan (200), and drives the fan (200) by a belt to drive the fan (200) to rotate. The fan (200) is driven by a belt pulley instead of being directly driven by the motor, so that the inner cavity of the housing (100) is fully utilized, the air exchange amount is increased as much as possible while reducing the occupied space, and the air purification efficiency is improved. The fan (200) is arranged in an air duct, the size of the fan is increased as much as possible by means of the size of the air duct, thereby improving the air exchange efficiency.
