Abstract

Claims (25)

1 . An aerosol-generating system comprising:

a pierceable capsule comprising an aerosol-forming substrate, and

a shisha device comprising:

a cavity configured for receiving the pierceable capsule, the aerosol-forming substrate comprising a liquid; and

a trough in fluid communication with the cavity, and

at least one opening element being formed as a piercing element, the at least one opening element being located upstream of the trough,

wherein the trough comprises an absorption element, the absorption element being configured for absorbing liquid originating from the pierceable capsule when the capsule is pierced by the piercing element of the at least one opening element.

2 . The aerosol-generating system according to claim 1 , wherein the trough is arranged downstream of the cavity.

3 . The aerosol-generating system according to claim 1 , wherein the trough comprises an annular shape.

4 . The aerosol-generating system according to claim 1 , wherein the trough is centred about a longitudinal central axis of the cavity.

5 . The aerosol-generating system according to claim 1 , further comprising a first airflow channel in fluid communication with the cavity, wherein the first airflow channel is configured as a central tubular first airflow channel.

6 . The aerosol-generating system according to claim 5 , wherein the trough is arranged around the first airflow channel.

7 . The aerosol-generating according to claim 6 , wherein the shisha device further comprises a second airflow channel of a stem pipe in fluid communication with the first airflow channel.

8 . The aerosol-generating system according to claim 5 , further comprising a connection element, wherein the connection element comprises or at least partially defines the first airflow channel.

9 . The aerosol-generating system according to claim 8 , wherein the trough comprises an inner wall, and a bottom wall, wherein the connection element further comprises one or both of said inner wall and bottom wall of the trough.

10 . The aerosol-generating system according to claim 9 , wherein the inner wall of the trough forms a portion of the first airflow channel.

11 . The aerosol-generating system according to claim 8 , wherein the connection element is configured removably attached to the shisha device.

12 . The aerosol-generating system according to claim 5 , wherein the first airflow channel is arranged along a longitudinal central axis of the cavity.

13 . The aerosol-generating system according to claim 1 , wherein the trough has a conically shaped outer wall.

14 . The aerosol-generating system according to claim 1 , wherein the trough comprises an inner wall, an outer wall, and a bottom wall, wherein said inner wall, outer wall, and bottom wall are integrally formed.

15 . The aerosol-generating system according to claim 1 , wherein the absorption element comprises a retention material or a high liquid retention material.

16 . The aerosol-generating system according to claim 15 , wherein the retention material or high liquid retention material is a fibrous retention material.

17 . The aerosol-generating system according to claim 1 , wherein the opening element and the trough are integrally formed.

18 . The aerosol-generating system according to claim 1 , wherein the absorption element is at or proximal to a bottom wall of the trough.

19 . Aerosol-generating system according to claim 1 , wherein the liquid comprises a liquid aerosol-former.
