AEROSOL GENERATING DEVICE

An aerosol generating device (10), comprising a heating base (17) and a heating member (19), wherein the heating base (17) is provided with a heating cavity (173); the heating member (19) is used for accommodating and heating an aerosol generating matrix (11); the heating member (19) is arranged in the heating cavity (173); the heating member (19) comprises a first side wall (191); a first airflow channel (21) is formed between the first side wall (191) and an inner surface of the heating cavity (173); an inner surface of the first side wall (191) is provided with protrusions (193); a second airflow channel (20) is formed between the first side wall (191) and the aerosol generating matrix (11) by the protrusions (193); and the first airflow channel (21) and the second airflow channel (20) both lead to the bottom of the heating cavity (173) from the outside of the aerosol generating device (10). The aerosol generating device (10) can solve the problem of the temperature of the inner periphery and of the outer periphery not being uniform when an aerosol generating matrix is heated.
