The vortex air guide channel 1020 is in a vortex shape. When the air flow in the air intake channel 101 and the heating channel 100 enters the vortex air guide channel 1020, the air flow flows along the vortex air guide channel 1020 to form a vortex air flow, and A suction force is generated on the air intake channel 101 and the heating channel 100 , thereby enhancing the suction force of the airflow in the air intake channel 101 and the airflow in the heating channel 100 , and realizing the suction of the aerosol in the heating channel 100 .
