Abstract:
Provided is an air purifier. The air purifier comprises a housing, an air inlet, a first air outlet, and a second air outlet. Air ducts are arranged in the housing, and the air inlet, the first air outlet, and the second air outlet are arranged on the housing. A first air duct is arranged between the air inlet and the first air outlet, and a second air duct is arranged between the air inlet and the second air outlet. The first and second air ducts are separately arranged in the housing. The first air duct may be used for arranging a first fan, and the second air duct may be used for arranging a second fan. In the dual air duct arrangement in the housing, the first fan arranged in the first air duct and the second fan arranged in the second air duct deliver different air outputs. The fan with higher air output is applied to hand drying functionality, and the fan with lower air output is applied to air purifying functionality. The high-speed fan and the low-speed first fan are independent of each other, eliminating the need for frequently switching the operation mode of the fans, avoiding excessive wear and tear, and prolonging the service life of the fans.
