Abstract

An elongate aerosol generation device having a housing includes: a top end at which an aerosol is provided; a bottom end which is opposed to the top end; and four sides between the bottom end and the top end in a substantially quadrilateral arrangement of two larger opposing sides and two smaller opposing sides. The bottom end is adapted such that the device can stand on the bottom end, and the four sides are smoothly curved in a direction from the bottom end to the top end.

First claim

The invention claimed is:

1 . An elongate aerosol generation device for vaporising tobacco products, the device having a housing comprising:
a top end at which an aerosol is configured to be provided; a bottom end which is opposed to the top end; and four sides between the bottom end and the top end in a substantially quadrilateral arrangement of two larger opposing sides and two smaller opposing sides, an access subassembly comprising the top end; and a housing subassembly comprising the bottom end, wherein the bottom end comprises a surface configured for supporting the device in a standing position such that the device can stand on the bottom end, and the four sides are smoothly curved in a direction from the bottom end to the top end, wherein the aerosol generating device further comprises: a heater subassembly including a heater and a heating chamber, the heater disposed within the heater subassembly to provide heat to or within the heating chamber, the heater subassembly suspended within the housing, the heater subassembly and an inner surface of the housing defining a space between the heater subassembly and the inner surface; a power-and-control sub-assembly comprising a power source and control circuitry, the control circuitry configured to control the supply of power from the power source to the heater, the power-and-control sub-assembly and the inner surface of the housing defining a space between the power-and-control sub-assembly and the housing; and a mounting cap attached to the access subassembly, wherein the heater subassembly and the power-and-control sub-assembly are held by the mounting cap and suspended within the housing.

2 . The aerosol generation device according to claim 1 , wherein the surface comprises a flat surface.

3 . The aerosol generation device according to claim 1 , wherein the bottom end is smoothly connected to each of the four sides by a respective curved connection portion.

4 . The aerosol generation device according to claim 1 , wherein the top end is smoothly connected to each of the four sides by a respective curved connection portion, and the top end is smoothly curved in a direction from one to another of each pair of opposing sides.

5 . The aerosol generation device according to claim 4 , wherein the top end comprises a sliding lid for opening and closing access to the aerosol generation device, the sliding lid being arranged to slide along a part of a smooth curve of the top end between the two smaller opposing sides.

6 . The aerosol generation device according to claim 5 , further comprising:
wherein the sliding lid is for opening and closing access to the heating chamber.

7 . The aerosol generation device according to claim 4 , wherein a curvature of each of the four sides and the top end is lower than a curvature of the connection portions.

8 . The aerosol generation device according to claim 1 , wherein each of the connection portions is curved along a length of the connection portion according to a parallel curvature of an adjacent side.
