[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a vertical flat ceramic atomization core. Background Art

[0002] As a core component, the atomizer core of an electronic atomizer device plays a crucial role in determining aerosol flavor, vapor volume, and other performance characteristics. Atomizer cores primarily come in two types: cotton cores and porous ceramic cores. Atomizer cores are assembled in two ways, depending on the metal heating wire: vertical-firing cores with the heating wire parallel to the airway, and horizontal-firing cores with the heating wire perpendicular to the airway. Compared to horizontal-firing ceramic cores, vertical-firing ceramic cores offer a smoother airway and better flavor reproduction.

[0003] Currently, vertical porous ceramic atomizer cores mainly include cylindrical mesh ceramic atomizer cores and spring wire ceramic atomizer cores. The spring wire ceramic atomizer core has weak explosive power and poor taste reproduction. Although the mesh ceramic atomizer core has a good taste, the metal heating wire is embedded in the inner surface of the cylindrical ceramic base, which has a complex manufacturing process, high cost, poor stability, high risk of wire embedment and warping, and is difficult to detect defects, which affects the stability of taste. Therefore, it is of great significance to provide a vertical ceramic atomizer core that can circumvent the pain points of cylindrical mesh ceramic atomizer cores and achieve the explosive power of cylindrical mesh ceramic atomizer cores and cotton cores, with good taste reproduction.
