Abstract

A shisha device article includes a vessel and an aerosol-generating element. The vessel defines an interior configured to contain a volume of liquid. The vessel also includes a head space outlet. The aerosol-generating element is in fluid connection with the vessel. The aerosol-generating element includes (i) a cartridge receptacle for receiving a cartridge containing an aerosol-generating substrate; (ii) a heating element defining at least two surfaces of the cartridge receptacle; and (iii) an aerosol outlet in fluid connection with the cartridge receptacle and a fresh air inlet channel in fluid connection with the cartridge receptacle. The fresh air inlet channel is arranged to preheat air prior to the air entering the cartridge receptacle.

First claim

The invention claimed is:

1. A shisha device comprising:
a vessel defining an interior configured to contain a volume of liquid, the vessel comprising a head space outlet; and
an aerosol-generating element in fluid connection with the vessel, the aerosol-generating element comprising:
a cartridge receptacle for receiving a cartridge containing an aerosol-generating substrate;
a heating element defining at least two surfaces of the cartridge receptacle; and
an aerosol outlet in fluid connection with the cartridge receptacle; and
a fresh air inlet channel in fluid connection with the cartridge receptacle, wherein the fresh air inlet channel is arranged to preheat air prior to the air entering the cartridge receptacle.

2. The shisha device according to claim 1 , wherein the heating element defines a top wall portion and a cylindrical sidewall portion of the cartridge receptacle.

3. The shisha device according to claim 1 , wherein the cartridge receptacle defines a cylinder, the cylinder having a height value and a diameter value and the diameter value is 1.5 to 5 times the height value, or the height value is 1.5 to 5 times the diameter value.

4. The shisha device according to claim 1 , wherein the cartridge receptacle defines a frusto-conical shape, the frusto-conical shape having a height value and a base diameter value and the base diameter value is 1.5 to 5 times the height value, or the height value is 1.5 to 5 times the base diameter value.

5. The shisha device according to claim 1 , wherein the heating element defines at least one surface of the fresh air inlet channel.

6. The shisha device according to claim 1 , wherein the heating element defines a top wall and a cylindrical sidewall portion of the cartridge receptacle and the fresh air inlet channel is at least partially defined by the heating element forming the top wall and the heating element forming the cylindrical sidewall portion of the cartridge receptacle.

7. The shisha device according to claim 1 , wherein the fresh air inlet channel is at least partially defined by a receptacle surface of the heating element and a cartridge received within the cartridge receptacle.

8. The shisha device according to claim 1 , wherein the fresh air inlet channel is at least partially defined by an inner surface of the heating element and an inner surface of the aerosol-generating element containing the heating element.

9. The shisha device according to claim 1 , wherein one or more apertures through the heating element define a portion of the fresh air inlet channel.

10. The shisha device according to claim 2 , wherein two or more apertures through the heating element top wall define a portion of the fresh air inlet channel.

11. The shisha device according to claim 1 , wherein the heating element comprises a resistive heating element.

12. The shisha device according to claim 1 , wherein the heating element comprises an inductive heating element.

13. A shisha assembly comprising:
a shisha device according to claim 1 ; and
a cartridge containing an aerosol-generating substrate, the cartridge containing an aerosol-generating substrate received within the cartridge receptacle of the aerosol-generating element.

14. The shisha assembly according to claim 13 , wherein the heating element is configured to heat but not burn the aerosol-generating substrate contained within the cartridge during operation.

15. An aerosol-generating element for a shisha device, comprising:
a cartridge receptacle for receiving a cartridge containing an aerosol-generating substrate;
a heating element defining at least two surfaces of the cartridge receptacle; and
an aerosol outlet in fluid connection with the cartridge receptacle and a fresh air inlet channel in fluid connection with the cartridge receptacle, wherein the fresh air inlet channel is arranged to preheat air prior to the air entering the cartridge receptacle.

16. The shisha device according to claim 1 , wherein the cartridge receptacle defines a cylinder, the cylinder having a height value and a diameter value and the diameter value is 1.5 to 4 times the height value, or the height value 1.5 to 4 times the diameter value.

17. The shisha device according to claim 1 , wherein the cartridge receptacle defines a cylinder, the cylinder having a height value and a diameter value and the diameter value is 1.5 to 3 times the height value, or the height value is 1.5 to 3 times the diameter value.

18. The shisha device according to claim 1 , wherein the cartridge receptacle defines a frusto-conical shape, the frusto-conical shape having a height value and a base diameter value and the base diameter value is 1.5 to 4 times the height value, or the height value is 1.5 to 4 times the base diameter value.

19. The shisha device according to claim 1 , wherein the cartridge receptacle defines a frusto-conical shape, the frusto-conical shape having a height value and a base diameter value and the base diameter value is 1.5 to 3 times the height value, or the height value is 1.5 to 3 times the base diameter value.
