An aerosol generator device has an elongate body with an interior passageway extending longitudinally to its mouth end. The device receives an interchangeable, pressurized canister charged with a nicotine containing liquid that is discharged in a metered dose on manual actuation of a button member that causes a valve in the canister to open and discharge through a discharge tube. A sleeve releasably couples the canister to the body. The button member is slidably mounted on the body for reciprocal movement along a trigger axis Y-Y′ extending transversely of the longitudinal axis X-X′ of the device, and has a manually depressible surface portion and a camming surface portion that drives a slidable nozzle member to press the discharge tube inwardly of the canister to open its valve and release liquid into the nozzle member. Nozzle forms an aerosol from the liquid, which is delivered to the consumer through outlets in the mouth end of the device.

Disclosed are a heating core assembly and an air heating atomization device. The heating core assembly includes a preheating passage, a tobacco pot, a heating element and a filter assembly. The tobacco pot is divided into a first pot body and a second pot body. The second pot body is communicated with the preheating passage. The heating element is arranged in the preheating passage. The filter assembly is removably installed in the second pot body and can be pushed into the second pot body again through the first pot body after being removed. During smoking, external air flow enters the preheating passage, and then the preheating passage discharges hot air to the second pot body, such that heat is uniformly sent into the first pot body to evaporate substance to be evaporated after passing through the filter assembly. Such design can improve air preheating efficiency while ensuring convenient cleaning.

A smoking article is disclosed herein. The smoking article includes a shell defining an interior space, a consumable substance within the interior space, a heat source effective to increase the temperature of at least a portion of the shell, and a label attached to at least a portion of the shell. The label includes a base film, a cover film, and a temperature dependent material disposed between the base film and the cover film. The temperature dependent material is configured to transition between a first appearance and a second appearance responsive to the increase of the temperature of at least a portion of the shell.

A method of assembling a tubular simulated cigarette, the method comprising providing an elongate hollow housing having an inhaling end and a refill end; inserting an outlet valve tube, a dip tube and a support from the refill end so that the support supports the proximal end of the dip tube in the housing; inserting a refill valve into the refill end and fixing it in place to form a composition reservoir with the dip tube placing the reservoir in fluid communication with an outlet orifice when the outlet valve tube is open; inserting a valve element into a recess in the side of the housing so that the valve element is positioned to selectively close the outlet valve tube; inserting a breath operated valve actuation mechanism laterally into the recess; and applying a cover to the recess.

A smoking article having a proximal end and a distal end is provided, including a combustible heat source disposed at the distal end; an aerosol-forming substrate downstream of the combustible heat source; a mouthpiece downstream of the aerosol-forming substrate and disposed at the proximal end; and a tubular element slideable from a first position towards the distal end to a second position. In the second position, the slideable element at least partially extends over the combustible heat source and is configured to reduce the air supply to the combustible heat source. The tubular element is configured to modify a heat output of the combustible heat source, and to control a resistance-to-draw of the smoking article by selectively covering air inlets.

A method and device are provided for volatilizing active and/or aroma materials for releasing an inhalable aerosol, wherein a fluid flows through a flow channel in a preferably cylindrical hollow body, wherein the fluid in the flow channel entirely or in part flows through at least one vaporizer membrane in a fluid stream, wherein the at least one vaporizer membrane has been and/or is wetted with a substance containing an active and/or aroma material to be vaporized, and wherein the fluid additionally contains thermal energy and vaporizes the substance on flowing through the vaporizer membrane and supplies the vaporized substance to the fluid stream.

A cartridge for use in an aerosol delivery device, the cartridge including: an outer housing configured to contain at least an aerosolizable composition, the outer housing including an exit portal at a proximal end thereof for passage of an aerosol; and a bottom cap positioned at a distal end of the outer housing that is configured for insertion into a receiving chamber of a control device of the aerosol delivery device. The outer housing defines a front face portion and a rear face portion interconnected with sidewalls, wherein the front face portion has an asymmetrical configuration relative to the rear face portion, such asymmetrical configuration being effective such that the cartridge engages the control device of the aerosol delivery device in only a single orientation. A control device is also provided herein.
