Abstract

A cartridge for an aerosol-generating system may include a first chamber housing defining a first chamber and a second chamber housing defining a second chamber that is separate from the first chamber. The first chamber may contain an aerosol-forming substrate in the form of a gel, and the second chamber may contain a source of a desired compound. The first and second chamber housings may be separate or separable structures.

Claims (52)

1. A cartridge for an aerosol-generating device, the cartridge comprising:

a first chamber housing defining a first blind chamber, the first chamber housing including,

a first thermally-conductive material;

a first gel in the first blind chamber, the first gel including,

a first gelling agent, and

a first aerosol-forming agent;

a second chamber housing defining a second blind chamber, the second chamber housing configured to be coupled to the first chamber housing in a first configuration, the second chamber housing configured to be separated from the first chamber housing in a second configuration, the second chamber housing including,

a second thermally-conductive material; and

a second gel in the second blind chamber, the second gel including,

a second gelling agent, and

a second aerosol-forming agent.

2. The cartridge of claim 1 , further comprising:

a retaining ring configured to at least partially surround the first chamber housing and the second chamber housing to fix the first chamber housing and the second chamber housing to one another.

3. The cartridge of claim 1 , wherein the first chamber housing and the second chamber housing are fixed to one another by a snap fitting, a screw fitting, a clip, a bracket, or any combination thereof.

4. The cartridge of claim 1 , wherein the first chamber housing and the second chamber housing cooperate to at least partially define a slot between the first chamber housing and the second chamber housing.

5. The cartridge of claim 4 , wherein

the slot is a blind slot configured to at least partially receive a heater,

the cartridge extends between a first end and a second end opposite the first end,

the first chamber housing and the second chamber housing are open at the first end, and

the blind slot is open at the second end.

6. The cartridge of claim 4 , wherein

the cartridge extends between a first end and a second end opposite the first end,

the slot extends continuously between the first end and the second end, and

the slot is configured to permit airflow between the first end and the second end.

7. The cartridge of claim 1 , wherein

the first thermally-conductive material includes aluminum, chromium, copper, gold, iron, nickel, silver, brass, steel, a ceramic, or any combination thereof, and

the second thermally-conductive material includes aluminum, chromium, copper, gold, iron, nickel, silver, brass, steel, a ceramic, or any combination thereof.

8. The cartridge of claim 1 , wherein

the first chamber housing defines a first airflow channel and a first inlet in fluid communication with the first airflow channel, and

the second chamber housing defines a second airflow channel and a second inlet in fluid communication with the second airflow channel.

9. The cartridge of claim 1 , wherein one of the first chamber housing and the second chamber housing defines a channel, the channel configured to receive a portion of the aerosol-generating device to facilitate alignment of the cartridge within the aerosol-generating device.

10. The cartridge of claim 1 , wherein the cartridge is free of a liquid transport element.

11. The cartridge of claim 1 , further comprising:

a mouthpiece.

12. The cartridge of claim 11 , wherein the mouthpiece defines an air inlet hole.

13. The cartridge of claim 11 , wherein the mouthpiece includes,

a filter.

14. The cartridge of claim 1 , further comprising:

one or more frangible barriers sealing the first blind chamber and the second blind chamber.

15. The cartridge of claim 1 , further comprising:

an electrical heater configured to heat the first gel and the second gel.

16. The cartridge of claim 1 , wherein

the cartridge defines a length ranging from 5 mm to 30 mm, and

the cartridge defines a diameter ranging from 4 mm to 10 mm.

17. The cartridge of claim 1 , wherein

the first gel is in a form of a first continuous gel mass, and

the second gel is in a form of a second continuous gel mass.

18. The cartridge of claim 1 , wherein

the first gel is in a form of a first plurality of gel elements, and

the second gel is in a form of a second plurality of gel elements.
