Abstract
An electronic scent-delivery system (10) is provided having one or more cartridges (100)
filled with scented oil and maintained within pockets (53) of a tray (50) slidable within a tray
support member (40) of a housing (20,30,60). Heating elements (76) are provided for
indirectly heating the scented oil to an evaporative state, and acutating apparatus (92) are
provided for engaging the cartridges to enable the scented evaporate to escape the
cartridges. A blowing apparatus (86) provides an airflow over the tops of the cartridges,
thereby directing the scented evaporate out of the housing through vents (65) in the
housing faceplate (60) and into the surrounding environment.
