<p>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 vaporisation cavity, wherein the vaporiser further comprises an airflow channeler 18 configured in use to channel airflow over the heating element 16. The airflow channeler 18 may be provided within the heating element 16 (e.g. fig 4) or outside of the heating element 16 (e.g. fig 9). The airflow channeler 18 may be a heating element support. Various different examples of the airflow channeler 18 are disclosed. It may be cylindrical, conical, polygonal or with a bulge in the middle. In an alternative embodiment, the airflow channeler may be provided at the end of an external heating element support (20, fig 10) having a channel in which the heating element 16 is supported, the airflow channeler comprising an end-cap (24, fig 10) with an annular aperture. The airflow channeler 18 serves to focus airflow over a specific part or parts of the heating element 16 during use of the device, to control the amount of active substance vaporised and inhaled by the user.</p> |
