Propellant-based aerosol generation devices and method

摘要

Disclosed is an aerosol generating device comprising a cartridge containing a propellant. When ignited, propellant gases expand through a diffuser, then through and into a clearing pad and then through and into a filler area, thereby de-agglomerating and fluidizing the filler and increasing pressure until a frangible end seal on the retainer end of the cartridge ruptures and releases the filler as an aerosol cloud. Methods for disseminating an aerosol and for using the device are also disclosed.
