Abstract

A consumable component for an aerosol provision system includes an outer housing including an outer wall extending between first and second end walls to define an interior chamber; a plurality of elements of solid aerosol forming material for generating an aerosol for user inhalation, wherein the plurality of elements of solid aerosol forming material are retained within the interior chamber by the housing and wherein the first and second end walls comprise openings to allow air to flow into the interior chamber through the first end wall and out of the interior chamber through the second end wall during use, and a heater located within the interior chamber and configured to heat the elements of solid aerosol forming material during use to generate a vapor for user inhalation.

First claim

1 . A consumable component for an aerosol provision system comprising:
an outer housing comprising an outer wall extending between a first end wall and a second end wall to define an interior chamber; a plurality of elements of solid aerosol forming material for generating an aerosol for user inhalation, wherein the plurality of elements of solid aerosol forming material are retained within the interior chamber by the housing and wherein the first end wall and the second end wall comprise openings to allow air to flow into the interior chamber through the first end wall and out of the interior chamber through the second end wall during use; and a heater located within the interior chamber and configured to heat the plurality of elements of solid aerosol forming material during use to generate a vapor for user inhalation.

2 . The consumable component of claim 1 , wherein the plurality of elements of solid aerosol forming material comprise elements of a solid substrate material holding a liquid aerosol precursor material.

3 . The consumable component of claim 1 , wherein the plurality of elements of solid aerosol forming material comprise tobacco.

4 . The consumable component of claim 1 , wherein the plurality of elements of solid aerosol forming material comprise calcium carbonate.

5 . The consumable component of claim 1 , wherein an average characteristic dimension for the plurality of elements of solid aerosol forming material is more than 1 mm.

6 . The consumable component of any claim 1 , wherein an average characteristic dimension for the plurality of elements of solid aerosol forming material is less than 5 mm.

7 . The consumable component of claim 1 , wherein the heater comprises an inductive susceptor configured to be inductively heated.

8 . The consumable component of claim 1 , wherein the heater comprises a resistance heater, and wherein the consumable component further comprises electrical contacts on the outer housing electrically connected to the resistance heater.

9 . The consumable component of claim 1 , wherein at least a part of the heater has at least one of:
a planar form, a tubular form, a rod-shaped form, or comprises a plurality of electrically conductive elements distributed through the plurality of elements of solid aerosol forming material.

10 . The consumable component of claim 1 , wherein the heater is mounted to at least one of the first end wall or the second end wall.

11 . The consumable component of claim 1 , wherein at least one of the first end wall or the second end wall comprises a cap fitted over an end of the outer wall or a plug fitted into an end of the outer wall.

12 . The consumable component of claim 1 , wherein at least a portion of the outer housing comprises at least one of: a paper material, a card material, a tobacco material, a ceramic material, a metallic material, a carbon material, or a plastics material.

13 . The consumable component of claim 1 , wherein the plurality of elements of solid aerosol forming material are arranged into different zones within the consumable component and wherein the heater is configured to selectively independently heat elements of the plurality of elements of solid aerosol forming material in the different zones.

14 . An aerosol provision system for generating a vapor, the aerosol provision system comprising:
the consumable component of claim 1 ; a consumable component receiving section for removably receiving the consumable component for use; and a power source for selectively supplying power to the heater in the consumable component to generate vapor from the solid aerosol forming material for user inhalation.

15 . The aerosol provision system of claim 14 , wherein the aerosol provision system further comprises electrical contacts for supplying power to the heater in the consumable component via corresponding electrical contacts on the housing of the consumable component.

16 . The aerosol provision system of claim 14 , wherein the aerosol provision system further comprises an induction heating coil for inductively supplying power to the heater.

17 . The aerosol provision system of claim 14 , wherein the aerosol provision system further comprises a sensor for measuring a temperature associated with the consumable component during use.

18 . The aerosol provision system of claim 14 , wherein the consumable component comprises a sole source of vapor precursor material for the aerosol provision system.

19 . Consumable component means for an aerosol provision system comprising:
outer housing means comprising outer wall means extending between first end wall means and second end wall means to define an interior chamber; a plurality of elements of solid aerosol forming means for generating an aerosol for user inhalation, wherein the plurality of elements of solid aerosol forming means are retained within the interior chamber by the housing means and wherein the first end wall means and the second end wall means comprise opening means to allow air to flow into the interior chamber through the first end wall means and out of the interior chamber through the second end wall means during use, and heater means located within the interior chamber and configured to heat the plurality of elements of solid aerosol forming means during use to generate a vapor for user inhalation.
