ELECTRONIC CIGARETTE ATOMIZATION CORE
An atomization core provides a core body having a central channel, a generally cylindrical, ceramic first layer having an outer diameter and an inner diameter, and a generally cylindrical, ceramic second layer having an outer diameter and an inner diameter. The central channel extends through the first and second layers. The first layer, the second layer, and the central channel are aligned about a central axis, and the inner diameter of the second layer is about equal to the outer diameter of the first layer.
