Description

CROSS-REFERENCE TO RELATED APPLICATIONS The present disclosure claims priority to Chinese Patent Application No. 202321846211.8, filed with the China Patent Office on July 12, 2023 and entitled "ELECTRONIC ATOMIZATION DEVICE", which is incorporated herein by reference in its entirety. TECHNICAL FIELD Embodiments of the present disclosure relate to the technical field of electronic atomization, and in particular, to an electronic atomization device. BACKGROUND During use of tobacco products (such as cigarettes and cigars), tobacco is burnt to generate tobacco smoke. People try to replace these tobacco-burning products by manufacturing products that release compounds without burning. An example of such products is a heating device that releases compounds by heating rather than burning a material. For example, the material can be tobacco or other non-tobacco products, and these non-tobacco products can contain nicotine or not. Aerosol providing products such as so-called electronic atomization devices are available as another example. These devices typically include liquid. After heated, the liquid is vaporized to generate inhalable aerosols. The liquid can include nicotine and/or a fragrance and/or an aerosol generating material (for example, glycerol). In a known electronic atomization device, a movable shield component is arranged on an air inlet to be operated by a user, so as to selectively open or close the air inlet, thereby preventing or allowing vaping.
