Abstract

An aerosol-generating device is provided, including: a housing having a chamber, an induction coil around at least part of the chamber; a heating compartment to receive an aerosol-generating article, being detachably insertable into the chamber, and including a cavity to receive the article; and a heating element arrangeable within and extending into the cavity in a longitudinal direction, configured to penetrate an aerosol-forming substrate included in the article and received in the cavity, the compartment further including a first open end to receive the article, and a second, base end opposite the first open end, the first open end and the base end connected by side surfaces including openings and locking elements, and the chamber including recesses corresponding to the locking elements to facilitate a snap-fit when the compartment is inserted into the chamber, the compartment further including a press button to allow release of the snap-fit connection.

First claim

The invention claimed is:

1. An aerosol-generating device, comprising:
a housing having a chamber,
an induction coil disposed around at least a portion of the chamber;
a heating compartment configured to receive an aerosol-generating article, the heating compartment being detachably insertable into the chamber of the housing, the heating compartment comprising a cavity configured to receive at least a portion of the aerosol-generating article; and
a heating element arrangeable within the cavity of the heating compartment, wherein the heating element extends into the cavity in a longitudinal direction of the cavity, and wherein the heating element is configured to penetrate an aerosol-forming substrate comprised in the aerosol-generating article and received in the cavity,
wherein the heating compartment further comprises a first open end configured to receive at least the portion of the aerosol-generating article, and a second, base end disposed opposite the first open end,
wherein the first open end and the base end of the heating compartment are connected by side surfaces, the side surfaces comprising openings,
wherein the side surfaces of the heating compartment comprise locking elements and the chamber of the housing comprises recesses corresponding to the locking elements of the heating compartment to facilitate a snap-fit when the heating compartment is inserted into the chamber of the housing, and
wherein the heating compartment further comprises a press button configured to allow release of the snap-fit connection.

2. The aerosol-generating device according to claim 1 , wherein the press button compresses the side surfaces of the heating compartment such that the locking elements in the side surfaces of the heating compartment disengage from the corresponding locking elements in the chamber of the housing.

3. The aerosol-generating device according to claim 1 , wherein the heating element is not integrally connected with the heating compartment.

4. The aerosol-generating device according to claim 1 , wherein the base end of the heating compartment comprises an aperture configured to receive the heating element.

5. The aerosol-generating device according to claim 4 , wherein the aperture is a slit configured to enable an insertion of a heating element with a blade shape.

6. The aerosol-generating device according to claim 4 , wherein the aperture is one or more holes configured for insertion of one or more pin-shaped heating elements.

7. The aerosol-generating device according to claim 1 ,
wherein the side surfaces are compressed during insertion of the heating compartment into the chamber of the aerosol-generating device, and
wherein compressing of the side surfaces facilitates a firm fit of the heating compartment within the chamber of the aerosol-generating device.

8. The aerosol-generating device according to claim 1 , wherein the first open end of the heating compartment comprises a protruding rim with a width larger than an internal width of the chamber.

9. The aerosol-generating device according to claim 7 , wherein the protruding rim has a same outer diameter as the housing of the aerosol-generating device and is configured to facilitate a smooth outer surface when the heating compartment is inserted into the chamber.

10. The aerosol-generating device according to claim 1 , wherein the heating compartment is movably coupled to the chamber between a first position and a second position, the first position being an operating position defined by the heating element being in contact with the aerosol-forming substrate, and the second position being an extraction position defined by the aerosol-forming substrate being partly separated from the heating element.

11. The aerosol-generating device according to claim 10 , wherein, in the second position, the heating compartment is partly removed from the chamber.

12. The aerosol-generating device according to claim 9 , wherein the heating compartment is movably coupled to the chamber between a first position and a second position, the first position being an operating position defined by the heating element being in contact with the aerosol-forming substrate, and the second position being an extraction position defined by the aerosol-forming substrate being separated from the heating element.

13. The aerosol-generating device according to claim 12 , wherein, in the second position, the heating compartment is fully removed from the chamber.

14. The aerosol-generating device according to claim 1 , wherein the heating compartment forms part of an external housing of the aerosol generating device, when coupled to the aerosol generating device.

15. The aerosol-generating device according to claim 10 , further comprising a guide pin configured to guide the heating compartment as the heating compartment is moved between the first and the second positions.
