Abstract

The inductive heating device ( 1 ) for aerosol-generation comprises a device housing ( 10 ) comprising a cavity ( 13 ) having an internal surface for receiving at least a portion of an aerosol-forming insert ( 2 ) comprising an aerosol-forming substrate and a susceptor. The device housing ( 10 ) further comprises a pin ( 14 ) extending into the cavity ( 13 ). The device ( 1 ) further comprises an induction coil ( 15 ) arranged along the pin ( 14 ) and a power source ( 11 ) connected to the induction coil ( 15 ) and configured to provide a high frequency current to the induction coil ( 15 ).

First claim

1 . Inductive heating device for aerosol-generation, the device comprising:
a device housing comprising a cavity having an internal surface for receiving at least a portion of an aerosol-forming insert comprising an aerosol-forming substrate and a susceptor, the device housing further comprising a pin extending into the cavity; an induction coil arranged along the pin; and a power source connected to the induction coil and configured to provide a high frequency current to the induction coil.

2 . Device according to claim 1 , wherein the induction coil is arranged within the pin and is not in contact with the cavity.

3 . Device according to claim 2 , wherein the induction coil is moulded into the pin.

4 . Device according to claim 1 , wherein the induction coil is wound around the pin.

5 . Device according to claim 1 , wherein the pin and the induction coil are arranged along a central longitudinal axis of the cavity.

6 . Device according to claim 1 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.

7 . Device according to claim 1 , wherein two of more induction coils are arranged along the pin and next to each other.

8 . Device according to claim 1 , wherein the pin is integrally formed with the device housing.

9 . Device according to claim 1 , wherein the device housing comprises retaining members for holding the aerosol-forming insert in the cavity when the aerosol-forming insert is accommodated in the cavity.

10 . Inductive heating and aerosol-generating system comprising a device according to claim 1 and an aerosol-forming insert comprising an aerosol-forming substrate and a susceptor, wherein the aerosol-forming substrate is accommodated in the cavity of the device and arranged therein such that the susceptor of the aerosol-forming insert is inductively heatable by electromagnetic fields generated by the induction coil.

11 . System according to claim 10 , wherein the aerosol-forming insert is one of a cartridge comprising a susceptor and containing a liquid, preferably comprising nicotine and a tobacco material containing unit comprising a susceptor.

12 . Device according to claim 2 , wherein the pin and the induction coil are arranged along a central longitudinal axis of the cavity.

13 . Device according to claim 3 , wherein the pin and the induction coil are arranged along a central longitudinal axis of the cavity.

14 . Device according to claim 4 , wherein the pin and the induction coil are arranged along a central longitudinal axis of the cavity.

15 . Device according to claim 2 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.

16 . Device according to claim 3 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.

17 . Device according to claim 4 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.

18 . Device according to claim 5 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.

19 . Device according to claim 13 , wherein a circumferential portion of the inner surface of the cavity and the pin are of cylindrical shape.
