Abstract

An aerosol generating device for heating an aerosol generating article to generate an aerosol for inhalation by a user includes an induction coil and a heating compartment arranged to receive an aerosol generating article. The device further includes a projecting element which projects into the heating compartment so that at least part of the projecting element is positioned inside an aerosol generating article received in the heating compartment, and at least part of the projecting element is inductively heatable in the presence of a time varying electromagnetic field.

Claims (29)

1. An aerosol generating device for heating an aerosol generating article to generate an aerosol for inhalation by a user, the aerosol generating device comprising:

an induction coil;

a heating compartment arranged to receive the aerosol generating article; and

a projecting element which projects into the heating compartment so that at least part of the projecting element is positioned inside an aerosol generating article received, in use, in the heating compartment;

wherein the projecting element comprises a plurality of projecting elements which project into the heating compartment from opposite ends of the heating compartment,

wherein at least part of the projecting element is inductively heatable, by the induction coil, in the presence of a time varying electromagnetic field, and

wherein the projecting element is removably mounted on the aerosol generating device.

2. The aerosol generating device according to claim 1 , wherein at least one of the plurality of projecting elements includes an air passage in communication with one or both of an air inlet and an air outlet of the aerosol generating device.

3. The aerosol generating device according to claim 1 , wherein at least one of said plurality of projecting elements is arranged at a first end of the heating compartment on the mouthpiece and at least one of said plurality of projecting elements is arranged at a second end of the heating compartment on the device body.

4. The aerosol generating device according to claim 1 , further comprising a device body including a controller.

5. The aerosol generating device according to claim 4 , further comprising a mouthpiece removably mounted on the device body, wherein the mouthpiece includes at least one of the plurality of projecting elements.

6. The aerosol generating device according to claim 4 , wherein at least one of the plurality of projecting elements is part of the device body.

7. The aerosol generating device according to claim 4 , wherein at least one of the plurality of projecting elements is removably mounted on the device body.

8. The aerosol generating device according to claim 7 , wherein the controller is configured to detect the mounting of at least one of the plurality of projecting elements on the device body.

9. The aerosol generating device according to claim 7 , wherein the controller is configured to detect the placement of an aerosol generating article in the heating compartment.

10. An aerosol generating system for generating an aerosol for inhalation by a user, the aerosol generating system comprising:

the aerosol generating device comprising:

an induction coil;

a heating compartment arranged to receive an aerosol generating article; and

a projecting element which projects into the heating compartment so that at least part of the projecting element is positioned inside an aerosol generating article received, in use, in the heating compartment;

wherein at least part of the projecting element is inductively heatable, by the induction coil, in the presence of a time varying electromagnetic field; and

an aerosol generating article comprising a sealing member which is arranged to be broken by the projecting element during positioning of the aerosol generating article in the heating compartment.

11. The aerosol generating system according to claim 10 , wherein the aerosol generating article comprises aerosol forming material defining a cavity in which the projecting element is positioned.

12. The aerosol generating system according to claim 11 , wherein the projecting element is spaced from the aerosol forming material.

13. A kit of parts comprising:

a plurality of aerosol generating articles each comprising aerosol forming material; and

an element at least part of which is inductively heatable in the presence of a time varying electromagnetic field and adapted for use individually with the plurality of aerosol generating articles by being positioned next to the aerosol forming material to heat the aerosol forming material to thereby generate an aerosol for inhalation by a user,

wherein the element is adapted for removable mounting in an aerosol generating device, and

wherein the element comprises an elongate element extending from a metallic mesh and an air-permeable glug positioned adjacent to the metallic mesh.
