The present disclosure relates to an aerosol delivery component comprising a tank defining a storage chamber for storing a first liquid aerosol precursor and an air bleed channel extending from an outside channel opening outside of the tank to an inside channel opening within the tank. The air bleed channel comprises an s-bend channel for retaining the first liquid aerosol precursor in an inverted orientation of the component. In this way, the air bleed channel may have a volume greater than 1% e.g. greater than 10% of the volume of the storage chamber.

Aerosol delivery component having an air bleed channel

An aerosol delivery device comprises: a storage for storing aerosol precursor liquid, the storage comprising an air bleed channel for permitting air to enter the storage as the storage empties of aerosol precursor in use; and a liquid transfer element for transferring aerosol precursor liquid from the storage to an aerosol generator, wherein the air bleed channel and the liquid transfer element are configured such that aerosol precursor liquid from the liquid transfer element forms an obstruction in the air bleed channel in use to reduce flow through the air bleed channel, the aerosol delivery device further configured such that the obstruction is removed to open the air bleed channel in response to a user drawing on the aerosol delivery device.

Aerosol delivery device

An aerosol delivery device comprises: a storage for storing an aerosol precursor; an aerosol generator comprising an aerosol generator portion configured to receive the aerosol precursor from the storage; an air flow passage configured to direct air past the aerosol generator portion to pick up the aerosol precursor from the aerosol generator portion to form an aerosol; and a barrier arrangement for inhibiting evaporation of aerosol precursor when the barrier arrangement is closed, the barrier arrangement being openable to permit generation of aerosol.

An aerosol delivery device comprises: an aerosol generator portion configured to receive a first aerosol precursor; an air flow passage configured to direct air past the aerosol generator portion to pick up the first aerosol precursor from the aerosol generator portion to form a first aerosol; and a support for maintaining the aerosol generator portion in a substantially central position in the air flow passage.

Aerosol delivery device with support for maintaining position of aerosol generator portion

The present disclosure describes an aerosol delivery component comprising a tank defining a storage chamber for storing a first liquid aerosol precursor and an air bleed channel extending from an outside channel opening outside of the tank to an inside channel opening within the tank. The air bleed channel has a volume between 1% and 20%, e.g. greater than 10% of the volume of the storage chamber. The air bleed channel may comprise an s-bend channel for retaining the first liquid aerosol precursor in an inverted orientation of the component.

Aerosol delivery component

There is disclosed an aerosol delivery device. The aerosol delivery device includes a first aerosol first aerosol sized for pulmonary penetration; and a second aerosol sized to inhibit pulmonary penetration. The second aerosol is transmissible within at least one of: a mammalian oral cavity and a mammalian nasal cavity, and the second aerosol comprising an active component for activating at least one of: one or more taste receptors in said oral cavity and one or more olfactory receptors in said nasal cavity. The second aerosol generator includes a Venturi aperture to generate the second aerosol. There is disclosed a consumable for a substitute smoking device and a substitute smoking system. The consumable includes an airflow passage between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member for passive aerosol generation. The airflow passage is constricted by the porous member to form a narrowed portion of the airflow passage. In another embodiment, the consumable also includes an inner porous member () for passive aerosol generation. The airflow passage has an annular portion surrounding at least a portion of the porous member. In another embodiment, a portion of the airflow passage is located between a porous surface of the porous member and an opposing airflow passage wall. A minimum distance between the porous surface of the porous member and the opposing airflow passage wall is less than 1000 microns. In another embodiment, the consumable also includes a porous member () for passive aerosol generation located within the airflow passage. The porous member is tapered along a longitudinal axis of the consumable. In another embodiment, the consumable has a longitudinal axis and includes an airflow passage () between an upstream inlet of the consumable and a downstream outlet of the consumable. The consumable also includes a porous member () for passive aerosol generation. A longitudinal cross section of the airflow passage includes an inclined portion forming a passage angle with the longitudinal axis of the consumable. The passage angle is greater than zero degrees and less than 90 degrees and a wall of the inclined portion is formed from a porous surface () of the porous member. In another embodiment, the consumable includes an active aerosol generator () for generating a first aerosol from a first aerosol precursor (), and a passive aerosol generator () for generating a second aerosol from a second aerosol precursor (). In another embodiment, the consumable also includes an aerosol generator for generating an aerosol. An external portion of the aerosol generator is located at the outlet of the consumable. In another embodiment, the consumable also includes an aerosol generator for generating an aerosol at an aerosol generation location. The aerosol generation location is substantially at the outlet located at a mouthpiece of the consumable. In another embodiment, the outlet is located at a mouthpiece portion of the consumable; and the mouthpiece portion includes a nozzle for control of an aerosol from the aerosol generator.
