Patent attributes
An air purifier includes a main housing, an air filter, a driving motor, a centrifugal fan, and an air outlet guider. The air outlet guider includes a central hub connected to the driving motor, a plurality of outlet guiding blades outwardly extended from the central hub, and a peripheral rim connected to the central hub at a distance from the central hub to form an air guiding cavity between the central hub and the peripheral rim. The outlet guiding blades extend in the air guiding cavity. When the driving motor is activated to draw air from the air inlet, the air is forced to sequentially pass through the filter assembly and the guiding cavity. The air in the air guiding cavity is diverted and guided by the outlet guiding blades to form a more streamlined flow which is to be discharged through the air outlet.
