ABSTRACT:
The air freshener device is adapted to be mounted on a ventilation duct in a vehicle or other closed space. The housing has a front side and a back side and respective input and output air ports defined thereon. Forced air, expelled from the ventilation ducts, enters the input air ports of the housing, causes a rotatable fan to rotate and generate arcuate and, preferably rotating, air currents in the generally hollow interior space defined by the housing. An air freshener pellet is disposed within the housing and the arcuate air flow, and preferably rotatable air flow, passes over the pellet, mixes with the expelled ventilation air and is ejected from the housing via the output air port.
