[0002] An electronic cigarette (also known as an "e-cigarette") or a vaping device is an electronic delivery system for generating an aerosol from an atomization matrix for a user to inhale. The atomization matrix can be a liquid (e.g., e-liquid, etc.) or a solid or gel (e.g., e-paste).

[0003] Generally, a traditional electronic cigarette mainly includes a cartridge storing an atomization matrix and a power supply device. The cartridge has a heating or evaporation device, such as an atomizer including an atomization core. The power supply device powers the atomization core to convert the atomization matrix in the cartridge into an aerosol for the user to inhale. In many electronic cigarettes, the user's inhalation activates the atomization core, vaporizing the liquid-form atomization matrix in the cartridge, and then the user inhales the generated aerosol through the mouthpiece. The existing electronic cigarettes have a single flavor and cannot meet the needs of users. There is an urgent need for an electronic cigarette with multiple flavors. Summary of the Invention
