Richard L. Doty - Philadelphia PA, US
Aaron Scott - Columbia MO, US
Ling Zhou - Bronx NY, US

International Classification:

A62C 31/00

Abstract:

A digital odor generator includes a housing and a cylindrically shaped odor chamber carried by the housing and including a plurality of separate odor compartments isolated from each other. A porous hollow cylinder, made of plastic or some other porous material, with an odorant therein is located in each of the odor compartments. A nozzle in the form of a truncated cone is operatively connected to the odor chamber. The nozzle includes an outer face having an enlarged central opening and a plurality of smaller openings surrounding the central opening; the number of smaller openings being equal to the number of odor compartments. The outer face of the nozzle is arranged so that a person can position his or her nose near the openings. Each of the smaller openings is associated with a different one of the odor compartments and is isolated from the others and from the central opening so that the odor from only one odor compartment can be emitted through only one of the smaller openings. A fan within the housing is adapted to pass fresh air through the central opening.
