Definitions

• the flavor granules may be configured to provide flavoring for the aerosol proportionally to the strength of a user’s puff.
• the porous matrix material may be water-soluble. This may ensure that only the at least one flavoring agent included in the porous matrix material is volatilized upon a user’s puff. Water vapor included in a user’s puff may not be able to dissolve the porous matrix material.
• the distal end of the aerosol generating device or the mouthpiece may also be referred to as the upstream end.
• Components, or portions of components, of the mouthpiece or the aerosol generating device may be described as being upstream or downstream of one another based on their relative positions with respect to the airflow path through the mouthpiece or the aerosol generating device.
• the tubular section may enable contact to a cartridge, in particular to a central hollow portion of an annular-shaped cartridge.
• the mouthpiece may comprise an outer wall.
• the outer wall may comprise at least one mouthpiece air inlet configured for allowing ambient air to enter the mouthpiece.
• the inlet portion of the mouthpiece may comprise the at least one mouthpiece air inlet.
• the mouthpiece may further comprise an outlet sealing layer.
• the outlet sealing layer may seal the outlet portion of the mouthpiece.
• the mouthpiece may further comprise an inlet sealing layer.
• the inlet sealing layer may seal the inlet portion of the mouthpiece. The presence of one or both of the outlet sealing layer and the inlet sealing layer may prevent the evaporation of the at least one flavoring agent out of the mouthpiece.
• a user may remove the inlet sealing layer and the outlet sealing layer before using the mouthpiece. After removal of the outlet sealing layer and the inlet sealing layer a user may connect the mouthpiece with one or both of an aerosol-generating article or the cartridge.
• the tubular section of the inlet portion may be positioned adjacent to the vaporizer assembly of the cartridge.
• the upstream end of the tubular section may be positioned adjacent to the vaporizer assembly of the cartridge.
• the aerosol-generating device may comprise electric circuitry.
• the electric circuitry may comprise a microprocessor, which may be a programmable microprocessor.

• the electric circuitry may comprise further electronic components.
• the electric circuitry may be configured to regulate a supply of power to the heater element.
• the aerosol-generating device may comprise a heating element.
• the heating element may be configured to heat an aerosol-generating article received in the cavity.
• the heating element may be configured to heat the aerosol-generating article to a temperature ranging from 220 degrees Celsius to 400 degrees Celsius, preferably from 250 degrees Celsius to 290 degrees Celsius. At these temperatures an aerosol may be generated from the aerosolforming substrate included in the aerosol-generating article.
• the heating element may comprise one or both of an inductive heating element and a resistive heating element.
• the inductive heating element may comprise an inductor coil disposed around at least a portion of the cavity and connected to a power supply.
• the power supply may be configured to provide an alternating electric current to the inductor coil, such that in use, the inductor coil may generate an alternating magnetic field to heat a susceptor by creating eddy currents.
• the susceptor may be part of one or both of the aerosolgenerating device and the aerosol-generating article received in the cavity of the aerosolgenerating device. Preferably, the susceptor may be part of the aerosol-generating device or the aerosol-generating article.
