Description

Atomizer and electronic atomization device Technical Field The embodiment of the application relates to the technical field of electronic atomization devices, in particular to an atomizer and an electronic atomization device. Background Smoking articles (e.g., cigarettes, cigars, etc.) burn tobacco during use to produce tobacco smoke. Attempts have been made to replace these tobacco-burning products by making products that release the compounds without burning. An example of such a product is a heating device that releases a compound by heating rather than burning a material. For example, the material may be tobacco or other non-tobacco products that may or may not contain nicotine. As another example, there are aerosol provision articles, for example, so-called e-cigarette devices. These devices typically contain a liquid that is heated to vaporize it, producing an inhalable vapor or aerosol. The liquid may comprise nicotine and/or a fragrance and/or an aerosol generating substance (e.g. glycerol). In the known device, such as a nebulizer, condensate is formed on the inner wall of the output channel during the output of the aerosol generated by the heating to the suction, and the output airflow is sucked.
