Abstract
An electronic smoking device is provided including a power supply portion comprising a power supply, an atomizer/liquid reservoir portion comprising a liquid reservoir storing a liquid, and an atomizer adapted to atomize the liquid stored in the liquid reservoir when operated by the power supply. The atomizer extends away from the liquid reservoir in a first direction (L). The atomizer comprises first atomizer sections, wherein each of the first atomizer sections defines an opening that is at least partly encircled by the first atomizer section. The sizes of the openings defined by the first atomizer sections decrease with increasing distance of the first atomizer sections from the liquid reservoir in the first direction.
