Abstract
A porous liquid conducting member with a smooth liquid conduction is provided, the liquid conducting member is of a porous material and provided with a hollow cavity therein, and includes an inner side and an outer side. The inner side or the outer side is configured to be in contact with a liquid, and is provided with an air exchange recess to form a thin-wall on the liquid conducting member. A wall thickness of the thin-wall is smaller than a wall thickness between the inner side and the outer side, enabling air to be conducted through the thin-wall. The air exchange recess is outside a heating area of the liquid conducting member, so that air can enter the liquid storage chamber through the air exchange recess during an atomizing process, to avoid porous channels in the heating area from being occupied by the air entering the liquid storage chamber.
