For example, the aerosol-generating substrate 20 may refer to any tobacco-containing material. More specifically, the aerosol-generating substrate 20 may refer to one or more of tobacco, tobacco derivatives, expanded tobacco, reconstituted tobacco, or tobacco substitutes, and the like.

As shown in fig. 3 and 4, the atomizing assembly 200 is provided with an air inlet 211, an atomizing cavity 212 and an air outlet 213 which are sequentially communicated, the air inlet 211 is communicated with the atomizing channel 111, and the atomizing assembly 200 is configured to conduct an atomizing medium into the atomizing cavity 212 so that the atomizing medium generates a second type of aerosol under heating of the first type of aerosol, that is, the atomizing medium absorbs heat emitted by the first type of aerosol to generate the second type of aerosol. The nebulization chamber 212 communicates with the nebulization channel 111 via the gas inlet 211, and the first type of aerosol in the nebulization channel 111 can flow directly into the nebulization chamber 212. For example, when the first type of aerosol with a high temperature in the nebulizing channel 111 flows into the nebulizing chamber 212, the heat thereof can be absorbed by the nebulizing medium in the nebulizing chamber 212, so that the nebulizing medium volatilizes or nebulizes to generate the second type of aerosol. Such an arrangement includes at least the following advantages: firstly, the atomizing cavity 212 has a heat dissipation effect, namely, cooling treatment, on the first type of aerosol with higher temperature flowing through the atomizing cavity; secondly, the heat emitted by the first type of aerosol can be absorbed by the atomizing medium, so that the phenomenon that the surface temperature of the shell 100 is too high due to the fact that the heat is directly diffused to the outside of the shell 100, a user is scalded, and user experience is influenced is avoided; thirdly, the second type aerosol generated after the atomizing medium in the atomizing cavity 212 absorbs heat is directly mixed with the first type aerosol, the aerosol is prepared efficiently and uniformly mixed, the consistency of the overall concentration of the mixed aerosol is favorably improved, and the stability of the mouth feeling of a user is further ensured.

The storage bin 220 can timely supply the atomizing medium to the atomizing pipe 210. The atomizing tube 210 may be a porous structure, such as ceramic or glass, and has a substantially tubular shape. The porous structure can be considered to be made of a microporous material having a certain porosity. In various embodiments, the porous structure may also be referred to as a hollow porous body, and exhibits a "porous" form at a microscopic level, so as to transport the atomizing medium inside the atomizing tube 210, and due to the characteristics of the porous structure, the atomizing medium is transported to the inner wall of the atomizing cavity 212 by gravity, capillary action, and the like, so that the atomizing medium can generate the second type of aerosol under the heating of the first type of aerosol flowing therethrough.

More specifically, as shown in fig. 4, 5 and 6, in some of these embodiments, a partition structure 214 is provided in the atomizing tube 210, and the partition structure 214 divides at least a partial chamber section of the atomizing chamber 212 into a plurality of mutually independent atomizing sub-chambers 215. It can be understood that, under the condition that the cross-sectional area is not changed, the partition structure 214 partitions the atomizing cavity 212 into a plurality of independent atomizing sub-cavities 215, and the total inner wall area of the plurality of atomizing sub-cavities 215 is larger than that of one total atomizing cavity 212, that is, the contact area with the first type of aerosol flowing through the first type of atomizing sub-cavities is increased, which is beneficial for the atomizing medium to absorb heat more quickly to volatilize or atomize, and simultaneously, the cooling effect of the atomizing cavity 212 on the first type of aerosol flowing through is improved better. Where "a plurality" may be considered "at least two". In an embodiment, the cross-sectional areas of the plurality of individual atomizing subchambers 215 may be equal; in another embodiment, the cross-sectional areas of the plurality of individual atomizing subchambers 215 may also be unequal.

For example, when the first type of aerosol with a relatively high temperature in the atomizing passage 111 flows from the atomizing passage 111 into the plurality of atomizing sub-chambers 215 of the second chamber segment H2, the atomizing medium in each of the plurality of independent atomizing sub-chambers 215 is atomized to form the second type of aerosol and mixed with the first type of aerosol to form a plurality of mixed aerosols.

Further, in the embodiment shown in fig. 3 and 4, the cross-sectional area of the side of the atomizer subchamber 215 adjacent the inlet 211 is greater than the cross-sectional area of the side of the atomizer subchamber 215 adjacent the first chamber section H1. It can be understood that, the smaller the cross-sectional area of the inside of the atomizing sub-cavity 215, the higher the flow velocity of the gas flowing through the inside of the atomizing sub-cavity 215, the faster the evaporation velocity of the atomizing medium, that is, the efficiency of generating the aerosol is also improved correspondingly, and meanwhile, the aerosol in the plurality of atomizing sub-cavities 215 has the fastest velocity at the minimum cross-sectional area and all converges at the first cavity section H1, which is helpful to improve the mixing effect of the aerosol.

The specific structure of the separating structure 214 is not limited herein, and it is only necessary that the separating structure 214 can separate the atomizing cavity 212 into a plurality of mutually independent atomizing sub-cavities 215. In other embodiments, the separating structure 214 may also be a separate structural component, i.e., the separating structure 214 may be disposed in the atomizing chamber 212 of the atomizing tube 210 by ultrasonic welding, bonding, clamping, etc.

Such a configuration ensures that the supply of the atomizing medium from the storage bin 220 to the atomizing pipe 210 and the content of the atomizing medium in all parts of the atomizing pipe 210 are balanced, and it can be understood that even in an extreme case where one of the conveying channels 221 is partially blocked, the atomizing medium can still be conveyed from the rest of the conveying channels 221 into the atomizing chamber 212 of the atomizing pipe 210, thereby ensuring the normal generation of the second type of aerosol.
