Abstract

A shisha device ( 100 ) includes a device air inlet ( 16 ); a device outlet ( 18 ); an aerosol chamber ( 130 ) and a vessel ( 17 ). The aerosol chamber has a chamber inlet ( 131 ) and a chamber outlet ( 18 ) and is configured to house a consumable comprising an aerosol-generating substrate ( 20 ). The vessel has a vessel inlet ( 16 ) and a vessel outlet ( 15 ) and defines an interior configured to contain liquid ( 19 ) when the device is in use. The device is configured such that, in use, airflow through the aerosol chamber that exits the chamber outlet exits the device outlet without flowing through the liquid stored in the vessel. Thus, water soluble constituents in the aerosol may be delivered to a user of the shisha device rather than being dissolved and trapped in the liquid in the vessel.

First claim

The invention claimed is:

1. A shisha device comprising:
a first device inlet;
a device outlet;
an aerosol chamber configured to house a consumable comprising an aerosol-generating substrate, wherein the aerosol chamber comprises a chamber inlet and a chamber outlet; and
a vessel comprising an interior configured to contain liquid when the device is in use, wherein the vessel comprises a vessel inlet and a vessel outlet,
wherein the device is configured such that, in use, airflow through the aerosol chamber that exits the chamber outlet exits the device outlet bypassing the liquid stored in the vessel,
wherein the device comprises an airflow path from the first device inlet to the vessel inlet to the vessel outlet to the chamber inlet to the chamber outlet and then to the device outlet.

2. The shisha device according to claim 1 , wherein the vessel inlet is the first device inlet.

3. The shisha device according to claim 1 , wherein airflow through the vessel from the vessel inlet to the vessel outlet is configured to flow through liquid housed in the vessel when a user puffs on the device.

4. The shisha device according to claim 3 , further comprising a one-way valve between the vessel inlet and the vessel outlet, wherein the one-way valve allows airflow from the vessel inlet to the vessel outlet and prevents airflow from the vessel outlet to the vessel inlet.

5. The shisha device according to claim 3 , further comprising a conduit having a first end operably coupled to the vessel inlet and a second end extending into the interior of the vessel below a liquid fill level.

6. The shisha device according to claim 1 , wherein the device is configured such that air that flows through the aerosol chamber from the chamber inlet to the chamber outlet flows through the aerosol-generating substrate, when positioned in the aerosol chamber.

7. The shisha device according to claim 1 , wherein the shisha device further comprises a heating element disposed in the aerosol chamber, wherein the heating element is configured to heat the aerosol-generating substrate to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate.

8. The shisha device according to claim 7 , wherein the heating element is operably coupled to control electronics configured to control the temperature of the heating element to cause the heating element to heat the aerosol-generating substrate to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate.

9. The shisha device according to claim 8 , wherein the shisha device comprises a receptacle configured to receive a consumable comprising the aerosol-generating substrate, wherein the heating element is positioned relative to the receptacle such that when the consumable is received in the receptacle the heating element may sufficiently heat the aerosol-generating substrate to an extent to generate an aerosol without combusting the aerosol-generating substrate.

10. The shisha device according to claim 1 , further comprising an air flow valve in communication with the aerosol chamber to control the resistance to draw of the shisha device.

11. The shisha device according to claim 1 , wherein the shisha device outlet is the chamber outlet.

12. A shisha device comprising:
a first device inlet;
a device outlet;
an aerosol chamber configured to house a consumable comprising an aerosol-generating substrate, wherein the aerosol chamber comprises a chamber inlet and a chamber outlet; and
a vessel comprising an interior configured to contain liquid when the device is in use, wherein the vessel comprises a vessel inlet and a vessel outlet,
wherein the device is configured such that, in use, airflow through the aerosol chamber that exits the chamber outlet exits the device outlet bypassing the liquid stored in the vessel,
wherein the device comprises a first airflow path through the aerosol chamber that bypasses liquid stored in the vessel, and
wherein the device comprises a second airflow path through liquid stored in the vessel that bypasses the aerosol chamber.

13. The shisha device according to claim 12 , further comprising a second device inlet,
wherein the first airflow path extends from the first device inlet to the chamber inlet to the chamber outlet and then to the device outlet, and
wherein the second airflow path extends from the second device inlet to the vessel inlet to the vessel outlet and then to the device outlet.

14. The shisha device according to claim 13 , wherein the vessel inlet is the second device inlet.

15. The shisha device according to claim 12 , wherein airflow through the vessel from the vessel inlet to the vessel outlet is configured to flow through liquid housed in the vessel when a user puffs on the device.

16. The shisha device according to claim 15 , further comprising a one-way valve between the vessel inlet and the vessel outlet, wherein the one-way valve allows airflow from the vessel inlet to the vessel outlet and prevents airflow from the vessel outlet to the vessel inlet.

17. The shisha device according to claim 12 , wherein the device is configured such that air that flows through the aerosol chamber from the chamber inlet to the chamber outlet flows through the aerosol-generating substrate, when positioned in the aerosol chamber.

18. The shisha device according to claim 12 , wherein the shisha device further comprises a heating element disposed in the aerosol chamber, wherein the heating element is configured to heat the aerosol-generating substrate to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate.

19. The shisha device according to claim 12 , further comprising an air flow valve in communication with the aerosol chamber to control the resistance to draw of the shisha device.

20. The shisha device according to claim 12 , wherein the shisha device outlet is the chamber outlet.
