An electronic vapor provision system includes a control unit and a cartridge configured to engage with and disengage from one another substantially along a longitudinal axis. The cartridge includes a reservoir of liquid to be vaporized, and the control unit includes a battery and a tube portion disposed along said longitudinal axis. The system further includes an induction heating assembly comprising a drive coil and a heater element. The heater element is located in the cartridge for vaporizing the liquid. The cartridge is configured to feed liquid from the reservoir onto the heater element for vaporization. The drive coil is located in the tube portion of the control unit and disposed about the longitudinal axis. The cartridge is located at least partly within the tube portion when engaged with the control unit, such that the heater element is within the drive coil.

An inductive heating assembly for generating an aerosol from an aerosol precursor material in an aerosol provision system, the inductive heating assembly including: a susceptor; and a drive coil arranged to induce current flow in the susceptor to heat the susceptor and vaporize aerosol precursor material in proximity with a surface of the susceptor, and wherein the susceptor includes regions of different susceptibility to induced current flow from the drive coil, such that when in use the surface of the susceptor in the regions of different susceptibility are heated to different temperatures by the current flow induced by the drive coil.

Inductive heating assemblies for generating an aerosol

A storage case for an electronic vapor provision device component having a reservoir for source liquid, the case defining an interior storage volume and including a receiving volume configured to receive at least one such component within the case; and at least one sealing means configured to inhibit liquid held in such a component received in the receiving volume from flowing into the interior storage volume.

Storage case

A user monitoring system includes an e-cigarette including a power source, and an electronic breath alcohol testing device for detecting alcohol detachable from the e-cigarette, in which when attached, the electronic breath alcohol testing device is operable to share at least part of an airflow path of the e-cigarette, and when attached, the electronic breath alcohol testing device is operable to share the power source of the e-cigarette.

Vapor diagnostic system

Embodiments of an electronic vapor provision system having a longitudinal axis are disclosed. The electronic vapor provision system includes a control unit and at least one cartridge configured to engage with and disengage from the control unit substantially along the longitudinal axis. The at least one cartridge includes a reservoir of liquid to be vaporized. The electronic vapor provision system further includes an induction heating assembly including at least one drive coil and a plurality of heater elements. The heaters elements are located in the at least one cartridge for vaporizing the liquid. The at least one cartridge is configured to feed liquid from the reservoir onto the heater elements for vaporization. The at least one cartridge is located, when engaged with the control unit, such that the heater elements are within the at least one drive coil. The electronic vapor provision system is configured to support selective energization of different heater elements from the plurality of heater elements.

Electronic vapor provision system

An aerosol provision system for generating an aerosol from a source liquid, the aerosol provision system including: a reservoir of source liquid; a planar vaporizer comprising a planar heating element, wherein the vaporizer is configured to draw source liquid from the reservoir to the vicinity of a vaporizing surface of the vaporizer through capillary action; and an induction heater coil operable to induce current flow in the heating element to inductively heat the heating element and so vaporize a portion of the source liquid in the vicinity of the vaporizing surface of the vaporizer. In some example the vaporizer further comprises a porous wadding/wicking material, e.g. an electrically non-conducting fibrous material at least partially surrounding the planar heating element (susceptor) and in contact with source liquid from the reservoir to provide, or at least contribute to, the function of drawing source liquid from the reservoir to the vicinity of the vaporizing surface of the vaporizer. In some examples the planar heating element (susceptor) may itself include a porous material so as to provide, or at least contribute to, the function of drawing source liquid from the reservoir to the vicinity of the vaporizing surface of the vaporizer.

Electronic aerosol provision systems

An electronic vapor provision system includes a cartridge for storing material heatable to generate an aerosol and a control unit housing a battery to provide electrical power for heating, the cartridge and the control unit separably connectable together by at least one latching element, the latching element including a foot, and a leg joined at a first end to the foot by a flexible resilient joint and having a first latch member, the foot anchored within one of the cartridge and the control unit, and the other of the cartridge and the control unit having a second latch member on a surface, and positioned and configured to engage with the first latch member when the cartridge and the control unit are brought together with a substantially linear motion, and disengage with the first latch member when the cartridge and the control unit are pulled apart, the engagement and disengagement enabled by movement of the leg of the latching element about the flexible resilient joint.

Mechanical connector for electronic vapor provision system

An aerosol delivery device including a mouthpiece end; an aerosol generation chamber in fluid communication with the mouthpiece end via a primary air channel, wherein the aerosol generation chamber comprises an aerosol source for generating an aerosol from a source material for inhalation by a user through the mouthpiece end during use; and a sensor for detecting when a user inhales on the mouthpiece end, wherein the sensor is in fluid communication with the mouthpiece end via a secondary air channel, and wherein the sensor is located further from the mouthpiece end than the aerosol source, and the secondary air channel bypasses the aerosol generation chamber.

Aerosol delivery device

A device for controlling electrical power supply in response to air pressure measurement includes an airflow path, a chamber having an aperture, a liquid flow restrictor configured to inhibit ingress of liquid into the chamber via the aperture, a pressure sensor located in the chamber and operable to detect, in the presence of the liquid flow restrictor, air pressure changes caused by air flow in the airflow path, and a circuit for converting air pressure changes detected by the pressure sensor to control signals for controlling output of power from a battery.
