  • Scent delivery system
    Patent number: 6619559
    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.
