Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and more particularly to an atomizer and electronic atomization device. Background Technology

[0002] Tobacco products (such as cigarettes, cigars, etc.) produce tobacco smoke by burning tobacco during use. Efforts are being made to replace these tobacco-burning products by creating products that release compounds without combustion.

[0003] Examples of such products are heating devices that release compounds by heating rather than burning materials. For example, the material may be tobacco or other non-tobacco products, which may or may not contain nicotine. As another example, there are aerosol-providing articles, such as so-called electronic atomizing devices. These devices typically contain a liquid that is heated to vaporize, thereby producing an inhalable aerosol. The liquid may contain nicotine and / or flavorings and / or aerosol-generating substances (e.g., glycerin). In known electronic atomizing devices, in the fabrication of the mesh heating element, the mesh heating section and conductive leads can be integrally formed from sheets of resistive alloy material by stamping or die-cutting, which is advantageous for the disordered separate welding of conductive leads onto the heating element; in the electronic atomizing device, conductivity is further achieved by riveting the conductive leads to electrical contacts for powering the heating element.

[0083] In the embodiment, the first electrode portion 44 and the first electrode portion 45, the second electrode portion 46 and the second electrode portion 47 have no mesh, and thus the first electrode portion 44 and the first electrode portion 45, the second electrode portion 46 and the second electrode portion 47 are dense.

[0084] In some embodiments, the first heating element 41 and the second heating element 42 have the same structural features.
