[0084] Specifically, an installation cavity 410 is provided in the device body 100, and the airflow driving device 130 is provided in the installation cavity 410; the installation cavity 410 has an air intake end and an air outlet end, and the air intake end is connected to the first air inlet 101; the air outlet end is connected to one end of the active channel 110, and the other end of the active channel 110 is connected to the first exhaust port 103. When the airflow driving device 130 is working, external gas can enter from the first air inlet 101 to form an airflow. After the airflow enters the installation cavity 410 through the air intake end, it flows to the air outlet end, and then enters the active channel 110 from the air outlet end. When the first atomization device 230 is working, the aerosol generated in the active channel 110 can be actively discharged from the first exhaust port 103 along with the airflow to form an aerosol. The aerosol enters the external environment, and the user can actively inhale the aerosol.
