A heater assembly for an aerosol-generating system includes a perforated glass substrate and a heater element. The heater element is provided in the glass substrate, on the glass substrate, or both in and on the glass substrate. The heater element includes a plurality of parallel strips between alternating rows of the perforations.

Apparatus and methods are described for use with a portion of plant material that includes at least one active ingredient. A vaporizing unit includes a heating element configured to heat the plant material, and a sensor configured to detect an indication of airflow rate through the vaporizing unit. Control circuitry is configured to receive an indication of the airflow rate through the vaporizing unit, and, in response thereto, to determine a smoking profile that is desired by the user. The control circuitry drives the heating element to vaporize the active ingredient of the plant material by heating the plant material according to the determined smoking profile. The control circuitry dynamically updates the smoking profile in response to changes in airflow rate over the course of a smoking session. Other applications are also described.

The control board is mounted on the main body. The first silicon sleeve is sleeved on the power button, and the second silicon sleeve is sleeved on the regulation button.

A battery device includes a main body and a rear cover removably connected to the main body. The main body has a first battery receiving compartment. The rear cover has a second battery receiving compartment. The first battery receiving compartment is configured to receive at least two batteries while the second battery receiving compartment is configured to receive at least one battery.

For the battery device, since the back cover is provided with the second battery receiving compartment cooperating with the first battery receiving compartment in the body, the apparatus applying the battery device has at least two supportable power levels. In this way, the battery device can be switched between a low power and a high power, eliminating the need of another battery device.

The aerosol-generating article is capable of being used with an electrically-operated aerosol-generating device. The aerosol-generating article is a consumable article having an outlet end, a distal end upstream from the outlet end, and a mid-point located an equal distance between the outlet end and the distal end. The article includes a first volatile liquid substrate contained within a first frangible capsule, the frangible capsule being located between the distal end and the mid-point, and a second volatile liquid substrate contained within a second frangible capsule, the second frangible capsule being located between the distal end and the mid-point. The article also includes a liquid retention medium, at least a portion the liquid retention medium being located between the distal end and the mid-point, wherein the article is configured to allow air to be drawn through the article from the distal end to the outlet end.

An e-vaping device may include a pre-vapor formulation tank configured to hold a pre-vapor formulation, an adaptor that includes a vaporizer assembly configured to vaporize the pre-vapor formulation, and a flavor insert positioned to receive vapors formed by the vaporizer assembly. The flavor insert may hold at least one flavorant. The tank, adaptor, and flavor insert may be a non-combustible vaping element that includes a channel into which the flavor insert may be inserted to be positioned to receive the vapors. The flavor insert and the vaporizer assembly may be at opposing ends of the channel. The flavor insert may be a detachable insert configured to be inserted into the tank element. The flavor element may be a tobacco element. The tobacco element may be at least a portion of a cigarette.

A method of manufacturing a flavored piece includes providing a matrix material providing at least one of a flavorant and an aroma, mixing the matrix material with the at least one of the flavorant and the aroma to form a mixture, and performing a fabricating process of the flavored piece. A flavored mouth-end piece for an e-vaping device includes a matrix material and at least one of a flavorant and an aroma, wherein the at least one of the flavorant and the aroma are distributed within the matrix material.

A flavor assembly for an e-vaping device cartridge is configured to provide mechanically-adjustable flavorant elution to form a flavored vapor. The flavor assembly may include at least one flavor material holding a flavorant and a exposure control mechanism configured to adjustably expose the at least one flavor material to the vaporizer assembly to adjustably control flavorant elution from the at least one flavor reservoir into the generated vapor. The flavor assembly may be included in a flavor assembly module. The flavor assembly module may include an interface configured to couple with a vaporizer assembly and direct generated vapors formed by the vaporizer assembly to the flavor assembly. The flavor assembly may include multiple flavor materials holding different flavorants. The exposure control mechanism may adjustably expose a selected flavor material. The flavor assembly may be included in an e-vaping device that includes control circuitry configured to control the exposure control mechanism.
