Abstract

An electronic aerosol provision system, comprising an air pathway between an air inlet and an air outlet; and a vaporiser for generating vapour into the air pathway; where the air pathway between the air inlet and the vaporiser is configured to support laminar airflow. The air pathway between the air inlet and the vaporiser includes one or more curved portions, where each of the one or more curved portions has a radius of curvature greater than 5 mm. The laminar flow helps to prevent the aerosol from mixing prematurely with the incoming air, which can lead to improved vaporization efficiency and a more consistent aerosol output.

Claims

1. An electronic aerosol provision system, comprising: an air pathway between an air inlet and an air outlet; and 5 a vaporiser for generating vapour into the air pathway, wherein the air pathway between the air inlet and the vaporiser is configured to support laminar airflow, wherein the air pathway between the air inlet and the vaporiser includes one or more curved portions, wherein each of the one or more curved portions has a radius of curvature 10 greater than 5 mm.

2. The electronic aerosol provision system of claim 1, wherein the air pathway comprises a linear channel between the air inlet and the vaporiser. 15

3. The electronic aerosol provision system of claim 1, wherein each of the one or more curved portions has a radius of curvature greater than 15mm.

4. The electronic aerosol provision system of any of claims 1 to 3, wherein the air pathway between the air inlet and the vaporiser is substantially free of obstructions that 20 would introduce turbulence into airflow along the air pathway.

5. The electronic aerosol provision system of any of claims 1 to 4, wherein the air pathway between the air inlet and the vaporiser is defined by one or more walls that are substantially free of topology that would introduce turbulence into airflow along the air 25 pathway.

6. The electronic aerosol provision system of any of claims 1 to 5, further comprising a facility to control turbulence within the air pathway. 30

7. The electrical aerosol provision system of claim 6, wherein said facility has at least first and second settings, the first setting providing a higher proportion of laminar flow relative to turbulence than the second setting.

8. The electrical aerosol provision system of claim 7, wherein the first setting produces 35 an aerosol having a smaller particle size than the second setting.

9. The electrical aerosol provision system of claim 8, wherein the first setting produces an aerosol having a median particle size that is at least 10%, preferably at least 20%, smaller than the median particle size of an aerosol produced by the second setting. 5

10. The electrical aerosol provision system of claim 8 or 9, wherein the first setting produces an aerosol having a median particle size less than 1 micron and the second setting produces an aerosol having a median particle size greater than 1 micron.

11. The aerosol provision system of any of claims 7 to 10, wherein the first setting 10 reduces particle coagulation compared to the second setting.

12. The aerosol provision system of any of claims 7 to 11, wherein the first setting reduces vapour deposition onto particles compared to the second setting. 15

13. The electronic aerosol provision system of any of claims 6 to 12, wherein the facility supports movement of the airflow pathway.

14. The electronic aerosol provision system of claim 13, wherein the movement of the airflow pathway is configured to introduce or remove a linear channel between the air inlet 20 and the vaporiser.

15. The electronic aerosol provision system of any of claims 6 to 12, wherein the facility comprises an airflow divider for dividing a portion of the air pathway into two or more channels.

16. The electronic aerosol provision system of any of claims 6 to 12, wherein the facility comprises an aperture having multiple shapes.

17. The electronic aerosol provision system of any of claims 6 to 12, wherein the facility 30 comprises one or more structures that are introduced into or altered within the air pathway.

18. The electronic aerosol provision system of any of claims 6 to 17, wherein the electronic aerosol provision system is configured to maintain a substantially constant airflow through the air pathway as the facility provides different levels of turbulence.

19. The electronic aerosol provision system of any of claims 6 to 18, wherein the facility can be set by a user to control turbulence.
