An aerosol generating device includes a cartridge configured to store an aerosol generating material, a main body to which the cartridge is detachably coupled, a first heater configured to heat a cigarette inserted into the aerosol generating device, a second heater configured to heat an aerosol generating material, and a processor configured to individually control the first heater and the second heater so that the aerosol generating device operates in one of a smokeless mode in which visible smoke is not generated and a smoke mode in which visible smoke is generated.

Aerosol generating device having a smoke mode and a smokeless mode

An aerosol generating article includes: a first segment impregnated with a first liquid composition; a second segment impregnated with a second liquid composition that is different from the first liquid composition; a cooling portion configured to allow an aerosol generated in the first segment or the second segment, to pass therethrough and cool the aerosol; and a filter portion having a hollow through which the aerosol that passed through the cooling portion flows.

An aerosol generating article includes: a first segment impregnated with a first liquid composition; a second segment impregnated with a second liquid composition that is different from the first liquid composition; a cooler configured to cool aerosol by allowing the aerosol, generated from the first segment or the second segment, to pass through the cooler; and a filter configured to filter the aerosol by allowing the aerosol having passed through the cooler to pass through the filter, wherein at least a portion of the filter is recessed to thereby form a cavity in the filter.

Aerosol generating article and aerosol generating system including the same

An aerosol generating article includes a first portion including an organic acid, a second portion including a nicotine freebase, a third portion including a cooling material, and a fourth portion including a filter material, wherein a nicotine salt is generated through an acid-base reaction of the organic acid and nicotine freebase that are vaporized by heating.

Aerosol generating articles comprising organic acids

An aerosol-generating system includes a cigarette and an aerosol-generating apparatus. The cigarette includes a medium part including a tobacco material, a flavor unit including a flavoring material and a moisturizer, and a wrapper configured to wrap the medium part and the flavor unit. The aerosol-generating apparatus includes a first heater arranged on a portion corresponding to the medium part and configured to directly heat the medium part and indirectly heat the flavor unit by using heat transmitted through the wrapper, and a processor configured to control the first heater to make the aerosol-generating apparatus operate in a smoke-free mode in which no visible smoke is generated.
