Abstract

A shisha device ( 100 ) for use with a cartridge ( 20 ) containing an aerosol-generating substrate ( 302 ) includes a vessel, a receptacle, and an electrical heating element. The cartridge comprises a housing surrounding the aerosol-generating substrate. The vessel defines an interior configured to contain liquid ( 19 ) and defines an outlet in communication with the interior of the vessel. The receptacle is configured to receive the cartridge. The heating element is configured to heat the aerosol-generating substrate in the cartridge to generate an aerosol when the cartridge is received by the receptacle. The heating element is configured to heat the tobacco substrate to an extent sufficient to generate the aerosol without combusting the aerosol-generating substrate.

First claim

The invention claimed is:

1. A shisha device for use with a first cartridge containing an aerosol-generating substrate, wherein the first cartridge comprises a housing surrounding the aerosol-generating substrate, the shisha device comprising:
a vessel defining an interior configured to contain liquid and defining an outlet in communication with the interior of the vessel;
a first receptacle configured to receive the first cartridge; and
a first electrical heating element configured to heat the aerosol-generating substrate in the first cartridge to generate an aerosol when the first cartridge is received by the first receptacle, wherein the first heating element is configured to heat the aerosol-generating substrate to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate,
wherein the first heating element is actuatable from a first position in which the first heating element does not extend into the first receptacle to a second position in which the first heating element extends into the first receptacle, wherein actuation of the first heating element from the first position to the second position causes the first heating element to pierce the first cartridge when the first cartridge is received by the receptacle, wherein insertion of the first cartridge into the first receptacle causes the first heating element to move from the first position to the second position.

2. The shisha device according to claim 1 , wherein the first heating element comprises a plurality of separately activatable zones configured to heat a separate portion of the aerosol-generating substrate in the first cartridge.

3. The shisha device according to claim 2 , wherein the separately activatable zones are sequentially activatable.

4. The shisha device according to claim 1 , further comprising:
a second receptacle configured to receive a second cartridge comprising a housing surrounding an aerosol generating substrate; and
a second electrical heating element configured to heat the aerosol-generating substrate in the second cartridge to generate an aerosol when the second cartridge is received by the second receptacle, wherein the second heating element is configured to heat the aerosol-generating substrate to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate.

5. The shisha device according to claim 4 , wherein the first receptacle is configured to receive a first cartridge comprising paper wrapped around the aerosol-generating article and wherein the second receptacle is configured to receive a second cartridge comprising paper wrapped around the aerosol-generating article.

6. The shisha device according to claim 4 , wherein the first and second heating elements are separately activatable.

7. The shisha device according to claim 4 , wherein the shisha device further comprises an aerosol detection apparatus and a control unit,
wherein the aerosol detection apparatus is operably coupled to the control unit, and
wherein the aerosol detection apparatus and the control unit are configured to detect a decrease in production of aerosol,
wherein the aerosol detection apparatus comprises a photoelectric detector, and
wherein the shisha device is configured to activate the first heating element until a decrease in production of aerosol is detected.

8. The shisha device according to claim 7 , wherein the wherein the control unit is configured to activate the second heating element upon the detection of the decrease in the production of aerosol.

9. The shisha device according to claim 1 , further comprising:
two or more additional receptacles, each configured to receive an additional cartridge comprising a housing surrounding an aerosol generating substrate; and
two or more additional electrical heating elements, each configured to heat the aerosol-generating substrate in the additional cartridges to generate an aerosol when the additional cartridges are received by the additional receptacles, wherein the additional heating elements are configured to heat the aerosol-generating substrate in the additional cartridges to an extent sufficient to generate an aerosol without combusting the aerosol-generating substrate.

10. The shisha device according to claim 9 , wherein the shisha device further comprises an aerosol detection apparatus and a control unit,
wherein the aerosol detection apparatus is operably coupled to the control unit,
wherein the aerosol detection apparatus and the control unit are configured to detect a decrease in production of aerosol,
wherein the aerosol detection apparatus comprises a photoelectric detector,
wherein the shisha device is configured to activate the first heating element until a decrease in production of aerosol is detected, and
wherein the control unit is configured to activate each additional electrical heating element in a sequential fashion in response detection of a decrease in production of aerosol from the previously heated additional cartridge.

11. The shisha device according to claim 1 , further comprising a separate receptacle configured to receive a separate cartridge, wherein the device, in use, forms an airflow path through the separate receptacle and to the outlet without being drawn through the liquid disposed in the vessel.

12. The shisha device according to claim 1 , further comprising a mouthpiece operably coupled to the outlet, wherein the mouthpiece comprises an actuatable element operably coupled to the heating element, such that actuation of the element causes the heating element to be activated.

13. The shisha device according to claim 1 , further comprising alert apparatus, wherein the alert apparatus is configured to cause a cue to be provided to a consumer when the aerosol-generating substrate in the first cartridge is depleted or nearly depleted.
