Abstract

An aerosol-generating system includes an aerosol-generating device and at least two consumables. Each consumable includes an aerosol-forming substrate. The aerosol-generating device further includes a device housing comprising at least two receiving chambers, wherein each consumable is accommodated in a separate receiving chamber of the at least two receiving chambers. The aerosol-generating device further includes at least two mouthpieces, wherein each mouthpiece of the at least two mouthpieces is aligned with a separate consumable of the at least two consumables and wherein the aerosol-generating device is configured to isolate airflows through separate, respective mouthpieces of the at least two mouthpieces.

First claim

The invention claimed is:

1. An aerosol-generating system comprising:
an aerosol-generating device, the aerosol-generating device including a device housing, the device housing including at least two receiving chambers;
at least two consumables including an aerosol-forming substrate, each consumable of the at least two consumables accommodated in a separate receiving chamber of the at least two receiving chambers; and
at least two mouthpieces, each mouthpiece of the at least two mouthpieces aligned with a separate consumable of the at least two consumables,
wherein the aerosol-generating device is configured to isolate airflows through separate, respective mouthpieces of the at least two mouthpieces.

2. The aerosol-generating system according to claim 1 , wherein at least one mouthpiece of the at least two mouthpieces is included in the aerosol-generating device.

3. The aerosol-generating system according to claim 1 , further comprising:
a mouthpiece assembly, the mouthpiece assembly including the at least two mouthpieces.

4. The aerosol-generating system according to claim 1 , wherein at least one consumable of the at least two consumables includes one mouthpiece of the at least two mouthpieces.

5. The aerosol-generating system according to claim 1 , wherein one consumable of the at least two consumables includes an aerosol-forming liquid and a heating element, the heating element configured to heat the aerosol-forming liquid.

6. The aerosol-generating system according to claim 1 , wherein one consumable of the at least two consumables includes a solid tobacco material.

7. The aerosol-generating system according to claim 1 , wherein the aerosol-generating device is a handheld device.

8. An aerosol-generating device, comprising:
a device housing including at least two receiving chambers, each receiving chamber of the at least two receiving chambers configured to receive and accommodate a separate consumable, each receiving chamber of the at least two receiving chambers including one of
a heating element configured to heat the separate consumable accommodated in the receiving chamber,
electrical contacts connectable to an external heating element of the separate consumable accommodated in the receiving chamber, the electrical contacts configured to heat the separate consumable accommodated in the receiving chamber, or
an induction coil configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the receiving chamber.

9. The aerosol-generating device according to claim 8 , further comprising:
at least two mouthpieces, wherein each mouthpiece of the at least two mouthpieces covers a receiving opening of a receiving chamber of the at least two receiving chambers based on the mouthpiece being mounted to the device housing.

10. The aerosol-generating device according to claim 9 , wherein each mouthpiece is connected to the device housing via a hinge.

11. The aerosol-generating device according to claim 9 , wherein
each mouthpiece of the at least two mouthpieces includes an inlet opening and an outlet opening, and the inlet opening is aligned with a receiving opening of a separate receiving chamber of the at least two receiving chambers.

12. The aerosol-generating device according to claim 9 , wherein the aerosol-generating device is configured to isolate airflows through separate, respective mouthpieces of the at least two mouthpieces.

13. The aerosol-generating device according to claim 9 , further comprising:
a mouthpiece assembly, the mouthpiece assembly including the at least two mouthpieces.

14. The aerosol-generating device according to claim 8 , wherein
at least one receiving chamber of the at least two receiving chambers includes a heating element, and
the heating element is in a receiving chamber wall or extends into the at least one receiving chamber.

15. The aerosol-generating device according to claim 8 , wherein
each receiving chamber of the at least two receiving chambers is elongate and has a longitudinal axis, and
the at least two receiving chambers extend in parallel in the device housing such that the longitudinal axes of the at least two receiving chambers extend in parallel.

16. The aerosol-generating device according to claim 8 , wherein
each receiving chamber of the at least two receiving chambers is elongate and has a longitudinal axis, and
the longitudinal axes of the at least two receiving chambers extend in different directions within the device housing.

17. The aerosol-generating device according to claim 8 , wherein the device housing includes three or more receiving chambers configured to receive and accommodate three or more consumables, the three or more receiving chambers including the at least two receiving chambers.

18. The aerosol-generating device according to claim 17 , wherein
each receiving chamber of the three or more receiving chambers is elongate and has a longitudinal axis, and
the longitudinal axes of the three or more receiving chambers extend in different directions and the longitudinal axes of adjacent receiving chambers intersect at an alignment angle, the alignment angles between the longitudinal axes of all of the adjacent receiving chambers being substantially equal.

19. The aerosol-generating device according to claim 8 , wherein the aerosol-generating device is a handheld device.
