An electronic smoking device, preferably an electronic cigarette, comprises a power cell (8, figs 2 & 3) and a vaporiser (10, figs 2 & 3), where the vaporiser comprises a heating element 16 and a heating element support 18, wherein the heating element 16 is on the inside of the heating element support 18. The heating element 16 is preferably located within an internal channel 22 of the heating element support 18. The internal channel 22 may have a variety of cross-sections, including polygonal (e.g. square, as shown) or circular (fig 9). When the internal cross-section is polygonal, this provides a gap between the heating element and the heating element support, to enable better vapourisation by the heating element. The heating element support may be made in two parts (figs 12-16) to enable easy access for inserting the heating element. The heating element support 18 may be porous, e.g. a porous ceramic, and may act as a liquid store for the product to be vapourised. |
