In one embodiment, the substrate 21 has a first surface 213, a second surface 214, and a side surface 215, the second surface 214 being disposed opposite the first surface 213, the side surface 215 connecting the first surface 213 and the second surface 214. Generally, the first surface 213 is adapted to contact an aerosol-generating substrate in communication with the reservoir 12, and the second surface 214 is adapted to contact a gas, such as the second surface 214 being in contact with the outside air, with the air in the nebulizing chamber 201, or with the air in the suction channel 30.

In the present embodiment, the aerosol-generating substrate on the side of the second surface 214 of the base 21 permeates to the side of the first surface 213 of the base 21 via the plurality of pore structures inside the base 21, which are communicated with each other and with the material surface, and the heat-generating body 22 is disposed on the first surface 213 to atomize the aerosol-generating substrate permeated to the first surface 213.

As shown in fig. 3 and 4, in the first embodiment, the base body 21 has a first surface 213 and a second surface 214 which are oppositely arranged, and the first surface 213 is the atomization surface 211. The via 212 extends from the first surface 213 to the second surface 214. The substrate 21 can absorb liquid from the side surface 215 to atomize the aerosol, and can absorb liquid from the second surface 214 to atomize the aerosol.

In the first embodiment, the through hole 212 is a through hole perpendicular to the first surface 213, which may facilitate the preparation of the through hole. When the through holes 212 are straight through holes perpendicular to the first surface 213, it is convenient to perforate the raw material once and then cut the raw material into a plurality of substrates 21, and it is also convenient to prepare the mold, which is efficient.

In the fourth embodiment, as shown in fig. 9, the through hole 212 may also be a through hole/non-through hole having an oblique angle with the first surface 213 or the side surface 215. When the through holes 212 are straight holes/non-straight holes with a certain oblique angle, the mold is not easy to be demoulded, and multi-hole punching cannot be simultaneously carried out, so that the punching efficiency is low. However, liquid can be sucked from the second surface 214, and the liquid suction device is suitable for a downward atomizing atomizer and can be specifically arranged according to requirements. It is understood that the through holes 212 may be one or more, and the extending directions may be parallel or non-parallel, as long as the number of the conductor leads 23 is matched, which is not limited in the present application.

Specifically, the inside of the conductor lead 23 may be a dense structure, as shown in fig. 12. The conductor lead 23 may also have a void 235 inside, and the void 235 is a bubble naturally formed during the process of filling the through hole 212 with a paste-like metal screen printing of a metal or alloy material to form the conductor lead 23. The conductor lead 23 and the substrate 21 of the porous ceramic structure are matched and co-fired to form an integral structure, the formed conductor lead 23 and the through hole 212 of the substrate 21 are in a co-fired embedded form, and can not be detached or fall off after co-firing and shaping, so that the reliability of the conductor lead 23 is greatly improved. Different from the prior art that the lead is arranged outside the matrix 21, or partially arranged inside the matrix 21 and partially arranged outside the matrix 21, the problem that the conductor lead 23 is easy to break or tear and damage in the production and assembly processes is solved.

The aperture 235 may be a through hole or a blind hole, as shown in fig. 13, and the aperture 235 may be an irregular aperture shape present in the conductor lead 23. As shown in fig. 14, the void 235 may be present on the surface of the conductor lead 23, or may be present inside the conductor lead 23, and the shape and size of the naturally formed bubble may be any shape and size by filling the slurry of the metal or alloy material into the through hole 212 through the screen printing process.

As shown in fig. 15, since the base body 21 has a porous structure, the side walls of the through holes 212 formed therein are uneven. In one embodiment, the sidewall of the conductor lead 23 has the protrusion 236, the sidewall of the through hole 212 has the recess 2121, and the protrusion 236 is embedded in the recess 2121, so that the edge where the conductor lead 23 is combined with the substrate 21 is rough, the combination is firmer, the conductor lead 23 is prevented from falling off from the substrate 21, and the stability is high. It is understood that since the protrusions 236 are embedded in the pores of the base 21, the height of the protrusions 236 is substantially identical to the pore diameter of the pores of the base 21, and the height of the protrusions 236 is 10-200 um. In other embodiments, the sidewall of the conductor lead 23 and the sidewall of the through hole 212 may also be smooth, which is not limited in the present application.

In the present embodiment, as shown in fig. 2, 3 and 11, the bottom of the pad 25 is provided with an ejector pin 26 that is in direct contact with the pad 25 for conducting the heating element 22 and the power module 2. When the thimble 26 is in operation, the force is applied in a longitudinal direction, i.e. from the first surface 213 to the second surface 214. When the thimble 26 exerts the effort, the mutual embedded structure of base member 21 and conductor lead 23 can play spacing effect, strengthens both conductive contact's stability, and mechanical properties is excellent simultaneously, prevents that conductor lead 23 from following base member 21 and coming off, and electrically conductive is also more stable.

The atomizing core comprises a base body, a heating body and a conductor lead, wherein the base body is provided with an atomizing surface and a through hole extending to the atomizing surface; the substrate is used for guiding the aerosol generating substrate to the atomizing surface; the heating body is arranged on the atomization surface and used for heating and atomizing the aerosol generating substrate to generate aerosol; the conductor lead is arranged in the through hole and is fixed with the base body to form an integral structure; the first end of the conductor lead is electrically connected with the heating element, and the second end of the conductor lead is used for connecting a power supply assembly. This application has changed the direction that heat-generating body and power are connected through setting up conductor lead wire in the base member with base member formation body structure, avoids the lead wire to shelter from the atomizing face, and the conductor lead wire and the base member contact stability of having solved ceramic atomizing core are relatively poor, the problem of easy damage, have promoted atomizing conversion efficiency to the utmost.
