Abstract

An aerosol-generating system is provided, including an aerosol-generating device having a heating chamber configured to heat an aerosol-forming substrate, the heating chamber including a first end having an opening, a second end having a base, and a side wall extending between the opening and the base; and a residue collector removably insertable into the heating chamber and positionable at or near the second end, the heating chamber further including a first side opening in the side wall and a second side opening in the side wall, opposite the first side opening, and the residue collector being insertable into the heating chamber and removable from the heating chamber through the first and the second side openings.

First claim

The invention claimed is:

1. An aerosol-generating system, comprising:
an aerosol-generating device having a heating chamber configured to heat an aerosol-forming substrate, the heating chamber comprising a first end having an opening, a second end having a base, and at least one side wall extending around the heating chamber between the opening and the base and around a circumference of the base; and
a residue collector removably insertable into the heating chamber and positionable at closer proximity to the second end than the first end,
wherein the heating chamber further comprises a first side opening in the at least one side wall and a second side opening in the at least one side wall, opposite the first side opening, and
wherein the residue collector is insertable into the heating chamber and removable from the heating chamber through the first and the second side openings.

2. The aerosol-generating system according to claim 1 ,
wherein the residue collector is positionable between the base of the heating chamber and the aerosol-forming substrate when the aerosol-forming substrate is received in the heating chamber.

3. The aerosol-generating system according to claim 1 ,
wherein the residue collector comprises a body having a first face, a second face, and a side wall extending between the first face and the second face, and
wherein, when the residue collector is positioned within the heating chamber, the second face is positioned adjacent the base of the heating chamber.

4. The aerosol-generating system according to claim 3 ,
wherein a lip projects from the first face of the residue collector around a periphery of the first face such that an open cavity is defined by the first face and the lip.

5. The aerosol-generating system according to claim 4 ,
wherein a plurality of projections project from the first face of the residue collector into the cavity defined by the first face and the lip.

6. The aerosol-generating system according to claim 3 ,
wherein the residue collector further comprises one or more slits extending between the first face and the second face.

7. The aerosol-generating system according to claim 3 ,
wherein the residue collector is provided as part of an array of residue collectors, and
wherein adjacent residue collectors in the array are releasably secured together at the side walls of the adjacent residue collectors.

8. The aerosol-generating system according to claim 1 , further comprising a heating assembly and a power supply configured to supply power to the heating assembly.

9. The aerosol-generating system according to claim 8 ,
wherein the heating assembly comprises a heater that projects into the heating chamber through the base.

10. The aerosol-generating system according to claim 9 ,
wherein the residue collector comprises a slot extending between the first face and the second face, and
wherein the slot is configured to receive the heater when the residue collector is positioned in the heating chamber.

11. The aerosol-generating system according to claim 10 ,
wherein the slot extends to a side wall of the residue collector such that the heater is configured to be received in the slot through the side wall.

12. The aerosol-generating system according to claim 11 ,
wherein the residue collector further comprises a plurality of cut-outs on opposite sides of the slot.
