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, a proximal end of each receiving chamber of the at least two receiving chambers exposed to an exterior of the device housing such that each receiving chamber of the at least two receiving chambers is configured to receive and accommodate the separate consumable through the proximal end,
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 in the at least one receiving chamber, the induction coil arranged in sidewalls of the at least one receiving chamber and surrounding the at least one receiving chamber.

2. The aerosol-generating system according to claim 1 , wherein at least one other 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 other 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 other receiving chamber.

4. The aerosol-generating system according to claim 1 , wherein at least one other 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 other receiving chamber, the electrical contacts configured to heat the separate consumable accommodated in the at least one other receiving chamber.

5. The aerosol-generating system according to claim 1 , 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.

6. The aerosol-generating system according to claim 1 , 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.

7. The aerosol-generating system according to claim 6 , 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 direction 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.
