Electronic smoking device and atomizer

A cartomizer for an electronic smoking device the cartomizer comprising:

• a liquid reservoir;
• a wick configured to draw liquid from the liquid reservoir;
• and
• an atomizer including a heating wire that is at least section-wise formed as a heating coil comprising a plurality of windings wrapped around the wick, the heating wire comprising a first section and a second section, the heating coil has a first winding, a last winding and at least one inner winding between the first winding and the last winding, wherein the at least one inner winding comprises the first section, the first winding comprises the second section, and the last winding comprises a third section, wherein the electrical resistance per length unit of the third section corresponds to the electrical resistance per length unit of the second section, wherein the electrical resistance per length unit of the first section differs from the electrical resistance per length unit of the second section to increase the electrical resistance per unit length of the first section to generate heat for vaporizing liquid.

An electronic smoking device including an atomizer comprising:

• a battery portion, including a battery;
• an atomizer/liquid reservoir portion configured for attaching to the battery portion, the atomizer/liquid reservoir portion including a liquid reservoir;
• a wick configured to draw liquid from the liquid reservoir;
• and
• the atomizer including a heating wire that is at least section-wise formed as a heating coil comprising a plurality of windings wrapped around the wick, the heating wire comprising a first section and a second section, the heating coil has a first winding, a last winding and at least one inner winding between the first winding and the last winding, wherein the at least one inner winding comprises the first section, the first winding comprises the second section, and the last winding comprises a third section, wherein the electrical resistance per length unit of the third section corresponds to the electrical resistance per length unit of the second section, wherein the electrical resistance per length unit of the first section differs from the electrical resistance per length unit of the second section to increase the electrical resistance per unit length of the first section to generate heat for vaporizing liquid.
