Abstract

Provided in the embodiments of the present application are an aerosol-generating product and an aerosol-generating system. The aerosol-generating product comprises a substrate segment, a filter segment, a support segment, a cooling segment and a stopper; the substrate segment is an integrated structure and has a first end and a second end which are opposite to each other in the length direction; the filter segment is arranged close to the second end of the substrate segment; the support segment and the cooling segment are arranged between the filter segment and the substrate segment; the stopper is arranged close to the first end of the substrate segment and is in stop fit with the substrate segment. The aerosol-generating product provided in the embodiments of the present application limits the substrate segment to a space between the support segment and the stopper or a space between the cooling segment and the stopper, such that the position of the substrate segment falling off is relatively stable, thereby reducing the probability of the substrate segment falling off under the action of gravity due to heating, shrinkage, deformation, etc., and the probability of the substrate segment coming out due to the vibration of the aerosol-generating product during transport and use processes, and improving the structural stability of the aerosol-generating product.
