The cartridge is detachably arranged in the accommodation cavity, and the pushing component is configured to drive a first orifice plate to slide so that first square holes of the first orifice plate are in communication with second square holes of the second orifice plate, allowing atomized e-liquid in the cartridge to enter into the gas channel.
