A control body is coupled or coupleable with a cartridge that is equipped with a heating element and contains an aerosol precursor composition, the control body and cartridge forming an aerosol delivery device. The control body includes a control component to control the heating element to activate and vaporize components of the aerosol precursor composition. The control body also includes a gas sensor configured to detect a presence of gas in an environment of the control body, and the gas sensor or control component are further configured to control operation of at least one functional element of the aerosol delivery device in response to the presence of gas so detected.

Various embodiments provide a pack for holding and re-charging an e-cigarette. The pack includes a pack battery; a body portion including a tube for receiving an e-cigarette; a re-charging mechanism for re-charging the e-cigarette received into the tube using the pack battery, wherein the e-cigarette can be re-charged in the tube without disassembly of the e-cigarette; and a dual activation mechanism comprising two separate triggers for causing the re-charging mechanism to begin re-charging the e-cigarette received into the tube using the pack battery. The re-charging begins only in response to the direct activation by a user of both of the separate triggers.

A control unit for an electronic vapor provision system includes a battery for providing electrical power to a heater which is used to produce vapor. The battery is a lithium iron phosphate battery. The battery provides an output voltage which remains at an approximately constant voltage level as the battery is discharged.

The present disclosure provides an aerosol precursor consumable, and an aerosol delivery device that comprises a control unit that defines a receiving chamber, and a removable and replaceable aerosol precursor consumable, at least a portion of the consumable configured to be received into the receiving chamber. The aerosol precursor consumable comprises a housing defining an outer wall, an aerosol precursor composition reservoir located in the housing and configured to contain an aerosol precursor composition, an atomizer located in the housing, and at least one aroma diffuser. The atomizer is configured to vaporize the aerosol precursor composition to generate an aerosol for oral delivery to a user, and the at least one aroma diffuser is configured to diffuse an aroma composition for olfactory delivery to the user.

A smoking article may include a cigarette incorporated within an electrically powered aerosol generating device that acts as a holder for that cigarette. The smoking article possesses at least one form of tobacco. The smoking article also possesses a mouth-end piece that is used by the smoker to inhale components of tobacco that are generated by the action of heat upon components of the cigarette. A representative smoking article possesses an outer housing incorporating a source of electrical power (e.g., a battery), a sensing mechanism for powering the device at least during periods of draw, and a heating device (e.g., at least one electrical resistance heating element) for forming a thermally generated aerosol that incorporates components of tobacco. During use, the cigarette is positioned within the device, and after use, the used cigarette is removed from the device and replaced with another cigarette.

An electronic inhalation device comprising a mouthpiece and a control unit, the control unit comprising a power cell and a computer, where the computer comprises a computer processor, a memory and an input-output means; wherein the device further comprises a transmitter connected to the computer and the computer is configured in use to collect and store use data relating to a user's use of the device in the computer memory and transmit the use data.

An electronic smoking device (10) is provided including a power supply portion (12) comprising a power supply (18), an atomizer/liquid reservoir portion (14) comprising a liquid reservoir (34) storing a liquid, and an atomizer (26) adapted to atomize the liquid stored in the liquid reservoir (34) when operated by the power supply (18). The atomizer (26) extends away from the liquid reservoir (34) in a first direction (L). The atomizer (26) comprises first atomizer sections (28a, 28b, 28c, 28d), wherein each of the first atomizer sections defines an opening (50a, 50b, 50c, 50d) that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.

An aerosol-generating system may include a liquid storage portion configured to hold aerosol-forming substrate, a vaporizer, and a pump. The liquid storage portion includes a movable wall and an outlet. The vaporizer includes a heating element having a structure that at least partially defines an internal passage. The pump may deliver liquid aerosol-forming substrate from the outlet of the liquid storage portion to the internal passage of the heating element. The pump may include a micro stepper motor with a drive shaft that is configured to rotate a particular amount based on performing an individual step, a piston connected to the movable wall, and a lead screw connecting the drive shaft to the piston and configured to translate rotation of the drive shaft into axial movement of the piston and the movable wall. The vaporizer may at least partially vaporize the delivered liquid aerosol-forming substrate.

A control circuit for a vapor provision system includes comprises a first controller with capability to control a first set of components in the vapor provision system; a second controller with capability to control a second set of components in the vapor provision system, at least one component in the second set being also in the first set; and a communication link between the first controller and the second controller by which at least one controller can monitor operation of the other controller; wherein one or both controllers is operable to, via the communication link, detect a fault with the capability of the other controller to control the at least one component and, in response, assume control of the at least one component.
