Abstract

There is provided an elongate aerosol-generating device having a polygonal transverse cross-section. The polygon includes at least six sides. The elongate aerosol-generating device includes a substrate receiving cavity configured to receive an aerosol-forming substrate, a heating element configured to heat an aerosol-forming substrate to generate an aerosol, and a power supply configured to provide power to the heating element. In addition, there is provided an aerosol-generating system, including the elongate aerosol-generating device, and a charging device including a cavity having a polygonal transverse cross-section corresponding to the polygonal transverse cross-section of the aerosol-generating device, the cavity being configured to receive the elongate aerosol-generating device.

Claims

1. An aerosol-generating system, comprising:

an elongate aerosol-generating device having a polygonal transverse cross-section, wherein the polygon comprises at least six sides; and

a charging device comprising a cavity having a polygonal transverse cross-section corresponding to the polygonal transverse cross-section of the aerosol-generating device, the cavity being configured to receive the elongate aerosol-generating device and comprising means for keying the elongate aerosol-generating device to the charging device,

wherein the means for keying comprises at least one notch configured to receive at least one corresponding protrusion on the elongate aerosol-generating device, and

wherein the at least one protrusion is a button configured to activate the elongate aerosol-generating device.

2. The aerosol-generating system according to claim 1, wherein the polygon comprises between seven and twelve sides.

3. The aerosol-generating system according to claim 1, wherein the polygon is a regular polygon.

4. The aerosol-generating system according to claim 1, wherein at least one end of the elongate aerosol-generating device is tapered.

5. The aerosol-generating system according to claim 1, wherein both ends of the elongate aerosol-generating device are tapered.

6. The aerosol-generating system according to claim 4, wherein a radius of an end face of the elongate aerosol-generating device or said at least one end is at least 50% of a maximum radius of the elongate aerosol-generating device.

7. The aerosol-generating system according to claim 4, wherein said at least one end of the elongate aerosol-generating device is tapered along at least 5% of a length of the device.

8. The aerosol-generating system according to claim 4, wherein the taper is linear or curved.

9. The aerosol-generating system according to claim 1, the elongate aerosol-generating device further comprising:

a substrate receiving cavity configured to receive an aerosol-forming substrate;

a heating element configured to heat the aerosol-forming substrate to generate an aerosol; and

a power supply configured to provide power to the heating element.
