Abstract
Official abstract text for this publication.
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 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A capillary element for an electronic smoking device comprising: outer metal meshes having capillarity; and inner metal meshes having a higher capillarity than the outer metal meshes, wherein the inner metal meshes are enclosed by the outer metal meshes, wherein the inner and outer metal meshes are configured and arranged to draw liquid towards a heating coil by capillary action, and wherein different capillary actions result in an overall capillary action which is directed from the outer metal meshes towards the inner metal meshes. 2. The capillary element of claim 1 , further comprising: a center metal mesh having a higher capillarity than the inner metal meshes and located between the inner metal meshes. 3. The capillary element of claim 1 , wherein the outer metal meshes abut or extend into a liquid reservoir. 4. The capillary element of claim 1 , wherein the inner and outer metal meshes differ in mesh size and/or filament thickness. 5. The capillary element of claim 1 , wherein the inner and outer metal meshes are staked.
