Abstract

A non-combustible aerosol system includes a heater configured to supply heat to a heating chamber and a housing configured to be inserted into the heating chamber. The housing defines an internal volume for containing a solid substrate. The housing includes a plurality of internal structures extending from a first end of the housing to a second end of the housing, the plurality of internal structures extending through the internal volume, the plurality of internal structures being configured to heat the solid substrate to generate an aerosol by conducting the heat supplied by the heater to the internal volume.

First claim

We claim:

1 . A cartridge for a non-combustible aerosol system, comprising:
a cartridge housing defining an opening to a chamber in at least one side of the cartridge housing; a heater configured to supply heat to the chamber in the cartridge housing, the heater extending transversely across an inner passage of the cartridge housing; and a pre-aerosol formulation housing configured to be inserted into the chamber, the pre-aerosol formulation housing including,
a first plate,
a second plate opposite the first plate, and
an outer wall extending between the first plate and the second plate, the outer wall including a material that conducts heat such that the outer wall conducts the heat supplied by the heater to heat a pre-aerosol formation in the pre-aerosol formulation housing.

2 . The cartridge of claim 1 , further comprising a piercing structure configured to pierce the pre-aerosol formulation housing, wherein the piercing structure comprises:
a first piercing element configured to pierce the first plate of the pre-aerosol formulation housing; and a second piercing element opposite the first piercing element configured to pierce the second plate of the pre-aerosol formulation housing.

3 . The cartridge of claim 2 , wherein the first piercing element and the second piercing element are configured to generate an air flow path through the pre-aerosol formulation housing to an outlet in the cartridge housing.

4 . The cartridge of claim 2 , wherein a first end of the housing includes a button configured to move the first piercing element into the first plate of the pre-aerosol formulation housing and to move the pre-aerosol formulation housing toward the second piercing element in response to a force applied to the button.

5 . The cartridge of claim 4 , wherein the piercing structure further includes a first rod, a second rod, a third rod, a first link, and a second link, the first link configured to couple the first rod and the second rod and the second link configured to couple the second rod and the third rod.

6 . The cartridge of claim 5 , wherein the first rod extends in a longitudinal direction and between the button and the first piercing element.

7 . The cartridge of claim 5 , wherein the second piercing element is integral with the third rod.

8 . The cartridge of claim 4 , wherein the first plate of the pre-aerosol formulation housing is configured to define the first end of the cartridge housing; and
the second plate of the pre-aerosol formulation housing is configured to define a second end of the cartridge housing of, the first and second ends of the cartridge housing being opposite sides of the cartridge housing.

9 . The cartridge of claim 1 , wherein the outer wall is one of solid and a mesh.

10 . The cartridge of claim 9 , wherein the outer wall is a mesh and provides an outlet for the aerosol.

11 . The cartridge of claim 1 , wherein the pre-aerosol formulation housing is cylindrical.

12 . The cartridge of claim 1 , wherein the non-combustible aerosol system is not configured to supply an electrical current to the pre-aerosol formulation housing.

13 . The cartridge of claim 1 , further comprising:
a sensor configured to detect air flow in the chamber; and a controller configured to supply power to the heater based on the detected air flow.

14 . The cartridge of claim 1 , further comprising:
a first outlet on a first side of the cartridge housing; and a second outlet on a second side of the cartridge housing.

15 . The cartridge of claim 14 , wherein the second outlet is a one-way valve.

16 . The cartridge of claim 1 , wherein the pre-aerosol formulation housing includes a plurality of internal structures extending from the first plate of the pre-aerosol formulation housing to the second plate of the pre-aerosol formulation housing, the plurality of internal structures extending through an internal volume, the plurality of internal structures being configured to heat the pre-aerosol formulation to generate an aerosol by conducting the heat supplied by the heater to the internal volume.

17 . The cartridge of claim 16 , wherein the first plate and the second plate are a first material and the plurality of internal structures are a second material, the first material and the second material are different.

18 . The cartridge of claim 16 , wherein the first plate, the second plate and the plurality of internal structures are a same material.

19 . The cartridge of claim 16 , wherein the plurality of internal structures are different materials. 20 The cartridge of claim 16 , wherein the solid substrate includes at least one of tobacco leaf, reconstituted tobacco, compressed tobacco rod, powdered tobacco, a sub-combination thereof or a combination thereof.
