FIELD: smoking accessories.

SUBSTANCE: invention relates to aerosol delivery devices, such as smoking articles; and in particular to aerosol delivery devices, which use electrically generated heat to form an aerosol (for example, smoking articles, commonly referred to as electronic cigarettes). Aerosol delivery device comprises a reservoir at least partially filled with an aerosol precursor composition; bubble-jet head in fluid communication with the reservoir, said bubble-jet head being configured to dispense the aerosol precursor composition from the reservoir; and a spray device configured to heat the aerosol precursor composition dispensed by the bubble-jet head to form aerosol, bubble-jet head and the spray device are firmly connected to each other. Aerosol forming method in the aerosol delivery device includes the direction of an air flow from the control body containing a power source through a cartridge containing the reservoir, dispensing the aerosol precursor composition from the reservoir by means of a bubble-jet head and heating the aerosol precursor composition dispensed from the reservoir by means of a bubble-jet head, bubble-jet head and the spray device are firmly connected to each other.

EFFECT: technical result of the invention is creation of aerosol delivery devices with improved functionality.
