Abstract:
1. A system for emanating fragrance vapor into a region exhibiting given atmospheric pressure, comprising: a receptacle having an internal cross-section defining liquid-vapor interface area, and extending to an access opening; a fragrance liquid phase within said receptacle having a liquid surface corresponding with said interface area and defining a vapor volume thereabove in gas flow communication with said access opening; a sub-pressure generator connectable in gas flow communication with said vapor volume through said access opening, and energizable to derive a lowered pressure below said given atmospheric pressure at said liquid surface effective to enhance the evaporative generation of a vapor phase above said liquid surface and at least the partial disbursement thereof through said access opening and into said region said sub-pressure generator further comprising: an evacuation chamber in vapor flow communication with said vapor volume from said receptacle access opening and having a chamber outlet to said region; and a fan located adjacent said chamber outlet actuable to lower pressure with said chamber to an extent deriving said lowered pressure; and further comprising: a bubbler passageway extending from an inlet in airflow communication with said region and a bubbler outlet located within said liquid phase and effective to create bubbles expanding the effective area of said liquid surface.
