Electronic smoking device and atomizer

An atomizer (26) for an e-cigarette comprising a heating coil 28 made of a heating wire 40 with a first section 44 and a second section 46, wherein the first section comprises an electrical resistance per length unit (ER/LU) that differs from an ER/LU of the second section. Preferably the heating coil has a first winding 48, a last winding 50 and a plurality of inner windings 52 between the first and last windings, wherein the inner windings comprise the first section and the first winding comprises the second section, and the last winding comprises a third section 54 with the same ER/LU as the second section. Preferably the ER/LU of the first section is at least 10 times higher than the ER/LU of the second section. The heating wire of the first section can have a smaller diameter than the second section, or be made of a first material with a different ER/LU to a second material for the second section. The first and second sections can be formed continuously or be interconnected by a material ...
