Abstract

An electrically operated aerosol-generating system is provided, including a device and a removable cartridge including an aerosol-forming substrate, an electrically operated vaporizer, and first electrical contacts connected to the vaporizer, the device including a main body defining a cavity configured to receive the cartridge, an electrical power source, second electrical contacts connected to the electrical power source and a mouthpiece portion, which, in a closed position, retains the first electrical contacts on the cartridge in contact with the second electrical contacts on the device. By providing a device and cartridge based system in which the device includes a main body and a mouthpiece portion, the components for the cartridge can be simplified as compared to known cartomizer type cartridges.

First claim

The invention claimed is:

1. An electrically operated aerosol-generating system, comprising:
a device and a removable cartridge,
the cartridge comprising an aerosol-forming substrate, an electrically operated vapouriser, and first electrical contacts connected to the vapouriser, and
the device comprising a main body defining a cavity and including an electrical power source, second electrical contacts connected to the electrical power source, and a mouthpiece portion, the cavity being configured to receive the cartridge,
wherein the mouthpiece portion, in a closed position, retains the first electrical contacts on the cartridge in contact with the second electrical contacts on the device.

2. The electrically operated aerosol-generating system according to claim 1 , wherein the mouthpiece portion is connected to the main body of the device by a hinged connection.

3. The electrically operated aerosol-generating system according to claim 1 , wherein the mouthpiece portion includes an air inlet and an air outlet, and is configured to allow a user to suck on the air outlet to draw air through the mouthpiece portion from the air inlet to the air outlet.

4. The electrically operated aerosol-generating system according to claim 3 , wherein the mouthpiece portion includes a baffle configured to direct air drawn through the mouthpiece portion from the air inlet to the air outlet past the vapouriser in the cartridge.

5. The electrically operated aerosol-generating system according to claim 1 , wherein the system is an electrically operated smoking system.

6. The electrically operated aerosol-generating system according claim 1 ,
wherein the vapouriser is a heater, and
wherein the cartridge further comprises
a liquid storage portion comprising a housing holding a liquid aerosol-forming substrate, the housing having an opening; and
a fluid permeable heater comprising a plurality of electrically conductive filaments, wherein the fluid permeable heater extends across the opening of the housing of the liquid storage portion.

7. The electrically operated aerosol-generating system according to claim 6 , wherein the heater is substantially flat.

8. The electrically operated aerosol-generating system according to claim 6 , wherein the housing of the liquid storage portion contains a capillary material.

9. The electrically operated aerosol-generating system according to claim 8 , wherein the capillary material is oriented in the housing to convey liquid to the heater.

10. The electrically operated aerosol-generating system according to claim 6 , wherein the first electrical contacts are in contact with the filaments of the plurality of electrically conductive filaments.

11. The electrically operated aerosol-generating system according to claim 10 , wherein the heater extends in a lateral plane and wherein the first electrical contacts extend laterally beyond the housing of the liquid storage portion.

12. The electrically operated aerosol-generating system according to claim 6 , wherein the housing of the liquid storage portion is substantially cylindrical, wherein the opening is at one end of the housing, and wherein the cavity is configured to receive the liquid storage portion.

13. The electrically operated aerosol-generating system according to claim 12 , wherein the opening is positioned at the one end of the housing closest to the mouthpiece portion, in use.

14. The electrically operated aerosol-generating system according to claim 6 , wherein the heater comprises an electrically insulating substrate on which the plurality of electrically conductive filaments and first contacts are supported, the filaments extending across an aperture formed in the electrically insulating substrate.

15. The electrically operated aerosol-generating system according to claim 1 , wherein the device further comprises one or more resilient elements configured to be deformed when the mouthpiece portion is in the closed position to urge the first electrical contacts into engagement with the second electrical contacts.
