Abstract
An atomizer/liquid portion for an electronic smoking device (10) is described and electronic smoking devices.Of the atomizer/liquid reservoir portion (14) and the electronic smoking devices, each has a liquid reservoir (34) for storing a liquid, and an atomizer (26) comprising a capillary element (30) and a heating coil (28). The capillary element (30) is configured to capillary draw the liquid from the liquid reservoir (34) towards the heating coil (28). The capillary element (30) comprises different metal meshes (310, 320, 330, 340) differing in capillarity. The different capillary actions result in an overall capillary action which is directed from the ends of the capillary element (30) towards a central portion of the capillary element (30).
