Propeller air freshener

Abstract

An air freshener employs a rotor made of a scent-bearing material to disperse a fragrance in the air flowing from a vent, for example, in a vehicle. The rotor can be molded from scented plastic (e.g., low-density polyethylene impregnated with a fragrance). The rotor is rotatably mounted to a base having a clip or fastener that can be attached to the louvers covering the vent. The air flow through the vent causes the rotor to rotate and thereby disperses the scent. The base can also be made of a scent-bearing material. For example, the rotor can be shaped like an aircraft propeller, pinwheel, or ventilation fan. If an aircraft propeller is used, the base can take the appearance of an aircraft engine cowling. The rotor can also be generally disk-shaped bearing an arbitrary design (e.g., a flower, character, or company logo). A series of openings direct air flow through the rotor disk and over corresponding airfoil surfaces to cause the rotor to spin.
