The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural view of an embodiment of an atomizing cartridge provided herein. The atomization core 10 comprises a heating layer 11, a liquid guide layer 12 and a porous base body 13, wherein the liquid guide layer 12 and the heating layer 11 are arranged in a stacked mode; the porous matrix 13 is arranged on one side of the liquid guide layer 12, which is far away from the heating layer 11; here, the liquid drainage uniformity of the porous substrate 13 is higher than the liquid drainage uniformity of the liquid drainage layer 12. Specifically, the drainage consistency is a determination factor of stability of the drainage capacity of the object for the liquid in unit time and/or unit volume, and the drainage consistency can be obtained through experimental tests, for example, the drainage quantity of the object X in unit time is a, the drainage quantity of the object X in another unit time is B, if the difference between a and B is within a preset range, the drainage consistency of the object X is high, and if the difference between a and B is within a non-preset range, the drainage consistency of the object X is poor. That is, since the smaller the difference in the liquid guiding amount of the object X in the same liquid guiding time indicates the higher the liquid guiding consistency thereof, it can be understood that the liquid guiding consistency of the porous substrate 13 is higher than the liquid guiding consistency of the liquid guiding layer 12, and the difference in the liquid guiding amount per two unit times of the porous substrate 13 is smaller than the difference in the liquid guiding amount per two unit times of the liquid guiding layer 12, thereby achieving uniform liquid guiding.

Specifically, the liquid locking capacity indicates the ability of the object to retain the liquid therein, and the liquid locking capacity can be obtained through experimental tests, for example, in a non-atomized state, the amount of liquid oozing out of the object X is a, the amount of liquid oozing out of the object Y is B, and if a is less than B, the ability of the object X to retain the liquid therein is strong, and the ability of the object Y to retain the liquid therein is poor, that is, the liquid locking capacity of the object X is greater than the liquid locking capacity of the object Y. Therefore, it can be understood that the liquid-locking ability of the porous substrate 13 is stronger than that of the liquid-conductive layer 12, meaning that the liquid-retaining ability of the porous substrate 13 is greater than that of the liquid-conductive layer 12, thereby achieving the purpose of preventing the liquid in the atomizing core 10 from leaking.

When the liquid guiding layer 12 is a ceramic layer, a dense ceramic layer, or a dense glass layer, the porous substrate 13 may be made of the same material as or different from the liquid guiding layer 12, but may not be inferior to the liquid guiding consistency of the liquid guiding layer 12, because of its high liquid guiding consistency and liquid locking capability, so as to avoid affecting the liquid supply to the liquid guiding layer 12.
