11 Claims

1. A three-dimensional atomization device for heating a porous liquid guiding material, comprising a porous liquid guiding material member for adsorbing liquid and a heating member for heating and atomizing the liquid adsorbed in the porous liquid guiding material member, wherein,

the porous liquid guiding material member has a plurality of outer surfaces, and the heating member is provided on at least two adjacent outer surfaces of the plurality of outer surfaces to form at least two heating surfaces; the porous liquid guiding material member has at least one outer surface that is not provided with the heating member; the heating member forms one or more metal heating trajectories on the heating surfaces, and the metal heating trajectory is rectangular wave-shaped;

the porous liquid guiding material member is capable of realizing a liquid transmission along a lengthwise direction which is defined as a first direction, and an airflow transmission along a second direction which is perpendicular to the second direction; each of the heating surfaces directly faces the direction in which the airflow flows to the porous liquid guiding material member; a central axis passing through the porous liquid guiding material member is provided along the second direction, and each of the heating surfaces is axisymmetric along the central axis.
