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, each receiving chamber of the at least two receiving chambers configured to receive and accommodate a separate consumable,
wherein each receiving chamber of the at least two receiving chambers is elongate and has a longitudinal axis, and
wherein the longitudinal axes of the at least two receiving chambers extend in different directions within the device housing.

2. The aerosol-generating system according to claim 1 , wherein at least one receiving chamber of the at least two receiving chambers includes a heating element configured to heat the separate consumable accommodated in the at least one receiving chamber.

3. The aerosol-generating system according to claim 2 , wherein the heating element is in a receiving chamber wall or extends into the at least one receiving chamber.

4. The aerosol-generating system according to claim 1 , wherein at least one receiving chamber of the at least two receiving chambers includes electrical contacts connectable to an external heating element of the separate consumable accommodated in the at least one receiving chamber, the electrical contacts configured to heat the separate consumable accommodated in the at least one receiving chamber.

5. The aerosol-generating system according to claim 1 , wherein at least one receiving chamber of the at least two receiving chambers includes an induction coil configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the at least one receiving chamber.

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

7. 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, each receiving chamber of the at least two receiving chambers configured to receive and accommodate a separate consumable,
wherein each receiving chamber of the at least two receiving chambers has receiving chamber walls that include two opposite and longitudinally arranged slits configured to enable a consumable to be removed from the receiving chamber via gripping the consumable via the two opposite and longitudinally arranged slits of the receiving chamber.

8. The aerosol-generating system according to claim 7 , wherein at least one receiving chamber of the at least two receiving chambers includes a heating element configured to heat the separate consumable accommodated in the at least one receiving chamber.

9. The aerosol-generating system according to claim 7 , wherein at least one receiving chamber of the at least two receiving chambers includes electrical contacts connectable to an external heating element of the separate consumable accommodated in the at least one receiving chamber, the electrical contacts configured to heat the separate consumable accommodated in the at least one receiving chamber.

10. The aerosol-generating system according to claim 7 , wherein at least one receiving chamber of the at least two receiving chambers includes an induction coil configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the at least one receiving chamber.

11. 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, each receiving chamber of the at least two receiving chambers configured to receive and accommodate a separate consumable; and
at least two mouthpieces, wherein each mouthpiece of the at least two mouthpieces covers a separate receiving opening of a separate receiving chamber of the at least two receiving chambers based on the mouthpiece being mounted to the device housing.

12. The aerosol-generating system according to claim 11 , wherein each mouthpiece is connected to the device housing via a hinge.

13. The aerosol-generating system according to claim 11 , further comprising:
a mouthpiece assembly, the mouthpiece assembly including the at least two mouthpieces.

14. The aerosol-generating system according to claim 11 , wherein at least one receiving chamber of the at least two receiving chambers includes a heating element configured to heat the separate consumable accommodated in the at least one receiving chamber.

15. The aerosol-generating system according to claim 11 , wherein at least one receiving chamber of the at least two receiving chambers includes electrical contacts connectable to an external heating element of the separate consumable accommodated in the at least one receiving chamber, the electrical contacts configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the at least one receiving chamber.

16. The aerosol-generating system according to claim 11 , wherein at least one receiving chamber of the at least two receiving chambers includes an induction coil configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the at least one receiving chamber.

17. 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, each receiving chamber of the at least two receiving chambers configured to receive and accommodate a separate consumable; and
at least two mouthpieces, 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 separate receiving opening of a separate receiving chamber of the at least two receiving chambers based on the mouthpiece being mounted to the device housing.

18. The aerosol-generating system according to claim 17 , wherein at least one receiving chamber of the at least two receiving chambers includes a heating element configured to heat the separate consumable accommodated in the at least one receiving chamber.

19. The aerosol-generating system according to claim 17 , wherein at least one receiving chamber of the at least two receiving chambers includes electrical contacts connectable to an external heating element of the separate consumable accommodated in the at least one receiving chamber, the electrical contacts configured to heat the separate consumable accommodated in the at least one receiving chamber.

20. The aerosol-generating system according to claim 17 , wherein at least one receiving chamber of the at least two receiving chambers includes an induction coil configured to heat a susceptor material provided in the aerosol-generating device or in the separate consumable accommodated in the at least one receiving chamber.
