Aerosol provision article

An aerosol provision article for use with an aerosol provision device for generating an inhalable medium comprising an aerosol, the aerosol provision article comprising:

• a first chamber for containing a first substance that is heatable to generate an aerosol, wherein the first substance is a liquid;
• a conduit that extends through the first chamber, the conduit having an inlet through which aerosol generated from the first substance can enter the conduit and an outlet through which the aerosol can exit the conduit, wherein the conduit comprises a first section that tapers from the outlet towards the inlet;
• and
• a second chamber for receiving a second substance, wherein the second chamber is downstream of the outlet of the conduit, the aerosol provision article being arranged such that in use aerosol exiting the outlet of the conduit passes through the second substance received in the second chamber, and wherein a cross-sectional area of the conduit increases at or towards the outlet,
• wherein:
• the first section tapers from the outlet to a first point along the conduit at a first rate and the conduit comprises a second section that tapers from the first point towards the inlet at a second rate that is lower than the first rate, or
• the first section tapers from the outlet towards a first point along the conduit at a first rate and the conduit comprises a second section that extends from the first point towards the inlet and has a substantially constant width.

A system comprising:

• an aerosol provision device for generating an inhalable medium comprising an aerosol, the aerosol provision device having a battery section;
• and
• an aerosol provision article for use with the aerosol provision device, the aerosol provision article comprising:
• a first chamber for containing a first substance that is heatable to generate an aerosol, wherein the first substance is a liquid;
• a conduit that extends through the first chamber, the conduit having an inlet through which aerosol generated from the first substance can enter the conduit and an outlet through which the aerosol can exit the conduit, wherein the conduit comprises a first section that tapers from the outlet towards the inlet;
• and
• a second chamber for receiving a second substance, wherein the second chamber is downstream of the outlet of the conduit, the aerosol provision article being arranged such that in use aerosol exiting the outlet of the conduit passes through the second substance received in the second chamber, and wherein a cross-sectional area of the conduit increases at or towards the outlet,
• wherein the aerosol provision article is connectable to the aerosol provision device.
