By means of the atomization apparatus, aerosol particles flowing through an aerosol output channel move irregularly, thereby increasing the probability of mutual collision of the aerosol particles; and aerosol particles having relatively small particle sizes are combined to form aerosol particles having relatively large particle sizes, thereby effectively reducing the proportion of aerosol particles having particle sizes of about 0.62 μm and 0.78 μm, and increasing the proportion of aerosol particles having particle sizes of about 1.32 μm. Therefore, most of the particle sizes of aerosol particles output by the atomization apparatus of the present application are 1 to 5 μm, thereby achieving a relatively high lung deposition rate, and effectively improving the effective utilization of effective components in an aerosol.

Abstract

A heater (11). The heater (11) is provided with an accommodating cavity (110) for accommodating an atomization medium carrier (20), and comprises: a magnetic field generation unit (200), which is arranged in the heater (11) and is used for generating an alternating magnetic field; a first sensing unit (300), which is at least partially accommodated in the accommodating cavity (110), wherein the first sensing unit (300) can be arranged in the atomization medium carrier (20) in a penetrating manner and generates heat by means of the alternating magnetic field; and a second sensing unit (400), which is located in the accommodating cavity (110) and is arranged surrounding the first sensing unit (300), wherein the second sensing unit (400) can surround the atomization medium carrier (20) and generates heat by means of the alternating magnetic field.
