Description

TECHNICAL FIELD Embodiments of this application relate to the aerosol generation technologies, and in particular, to an aerosol generation apparatus. BACKGROUND An aerosol generation apparatus is an apparatus capable of atomizing a liquid preparation to form an aerosol. However, in some exemplary related arts, the aerosol generation apparatus usually has only one cartridge for storing the liquid preparation. A capacity and types of liquid substrates stored in the aerosol generation apparatus are limited due to limitation of a volume of a single cartridge, affecting user experience. US 2016/366940 A1 describes an electronic cigarette comprising a battery base and an atomization base rotationally connected to the battery base. At least two atomizers used for electrically connecting to the battery base are arranged in the atomization base.
