Thus, when the porous medium 6 is mounted on the atomizing core 2, the porous medium 6 can cover the liquid inlet 24 of the atomizing core 2, so that the liquid storage cavity 13 cannot be directly in communication with the liquid inlet 24, to prevent the aerosol-forming substrate in the liquid storage cavity 13 from entering the atomizing cavity 25 directly through the liquid inlet 24. It can be understood that the outer contour of the porous medium 6 can be in the shape of a cylinder, an elliptical cylinder or a prism, etc. Moreover, the shape and size of the porous medium 6 is adapted to the shape and size of the liquid storage cavity 13.
