Abstract

This invention relates to a heating element, which is a flat sheet structure formed by etching a metal sheet. It includes a heating section, conductive sections extending from both ends of the heating section, and extension sections extending from the conductive sections away from the heating section. The cross-sectional area of ​​the conductive sections gradually increases from the end closest to the heating section to the end closest to the extension section, and the minimum cross-sectional area of ​​the conductive sections is greater than the cross-sectional area of ​​the extension sections and the cross-sectional area of ​​the heating segment within the heating section. This invention facilitates mass production by connecting the extension sections at both ends of the heating element to the etched frame area of ​​the metal sheet. By defining a gradually changing cross-sectional area of ​​the conductive sections, sufficient support strength is ensured for the heating section while minimizing heat generation in the conductive sections when the heating element is energized. This also reduces heat conduction from the heating section to the conductive sections, concentrating the generated heat in the heating section area, resulting in better atomization and improved heat utilization efficiency.
