Thus, the microporous structure of the porous substrate 1 is able to form capillary action, while the aerosol-forming substrate outside the porous substrate 1 is adsorbed into the microporous structure of the porous substrate 1, and the microporous structure of the porous substrate 1 penetrates the adsorbed aerosol-forming substrate to the surface of the porous substrate 1. As can be understood, referring to fig. 1 and 4, the heat conducting membrane 2 is disposed on at least one side surface of the porous substrate 1, one side of the heat conducting membrane 2 facing the porous substrate 1 has a bonding surface (not shown), the heat conducting membrane 2 is bonded to the surface of the porous substrate 1 through the bonding surface, one side of the heat conducting membrane 2 facing away from the bonding surface has an atomizing surface 4 for heating and atomizing the aerosol-forming substrate, and the heat conducting membrane 2 is a porous medium layer capable of adsorbing the aerosol-forming substrate on the surface of the porous substrate 1 and penetrating into the atomizing surface 4, so that after the heat conducting membrane 2 is tightly attached to the surface of the porous substrate 1, the heat conducting membrane 2 can form a transition heat conducting layer on the surface of the porous substrate 1. The heating element 3 is formed on the atomizing surface 4 in a thick film mode, and the heat conductivity of the heat-conducting membrane 2 is larger than that of the porous matrix 1. When the heating element 3 is in heating operation, the heat conductivity of the transition heat conduction layer (the heat conduction membrane 2) can reach 0.0628-0.0963J/cm DEG C.s because the transition heat conduction layer (the heat conduction membrane 2) is made of silicon carbide or silicon nitride or a mixed material of the silicon carbide and the silicon nitride, the thermal conductivity of the transitional heat-conducting layer (heat-conducting membrane 2) is much greater than that of the porous matrix 1, the heat generated by the heat generating member 3 can be rapidly and uniformly transferred to the respective areas of the atomizing surface 4 through the transitional heat-conducting layer (heat-conducting membrane 2), so that the heat is uniformly distributed on the whole atomization surface 4, the heating area of the aerosol-forming substrate is increased, make aerosol form substrate be heated evenly, avoid atomizing face 4 to produce because of local high temperature and generate heat inhomogeneous even the phenomenon that dry combustion method appears, and then make the atomizing core have good atomization effect, promote user's taste.

In addition, the thickness of the heat-conducting membrane 2 is 0.08-0.1 mm, the thickness of the heat-conducting membrane is small, the heat transfer distance of the heat transfer of the transition heat-conducting layer (the heat-conducting membrane 2) to the surface of the porous substrate 1 is reduced, the aerosol-forming substrate is preheated before penetrating into the atomization surface 4, the heat capacity of the transition heat-conducting layer (the heat-conducting membrane 2) is reduced, the heating efficiency of the heating element 3 to the aerosol-forming substrate is effectively improved, the aerosol-forming substrate is uniformly heated, and the phenomenon that the aerosol-forming substrate is directly heated to high temperature (about 1300 ℃) instantly from normal temperature (room temperature) to cause oil explosion is prevented. Moreover, under the condition that the permeability of the transition heat conduction layer (the heat conduction membrane 2) is smaller than that of the porous matrix 1, for aerosol formation matrix with higher viscosity at room temperature, the thickness of the heat conduction membrane 2 is 0.08-0.1 mm, the thickness of the heat conduction membrane is thinner, the penetration distance from the surface of the porous matrix 1 to the atomization surface 4 is reduced, so that the aerosol formation matrix after rapid preheating can pass through the transition heat conduction layer (the heat conduction membrane 2) at a relatively higher speed in a short time, and the phenomenon that the aerosol formation matrix cannot reach the atomization surface 4 in time and atomization cores are dried and burnt due to insufficient liquid penetration speed of the transition heat conduction layer (the heat conduction membrane 2) caused by poor flowability of the aerosol formation matrix is effectively avoided.
Compared with the prior art, the atomization core provided by the embodiment of the utility model has the advantages that the heat-conducting membrane 2 is covered on the surface of the porous matrix 1 which adsorbs and permeates the aerosol to form the matrix, so that the heat-conducting membrane 2 forms a transition heat-conducting layer with higher heat conductivity on the surface of the porous matrix 1. Then generate heat 3 during operation that generates heat, the heat accessible transition heat-conducting layer that generates heat 3 and produce transmits atomizing face 4 fast evenly for heat evenly distributed is on whole atomizing face 4, and then makes aerosol formation matrix be heated evenly, effectively avoids atomizing face 4 of atomizing core to appear the phenomenon of dry combustion method because of local high temperature, and then makes atomizing core have good atomization effect, promotes user's taste. And the low-permeability transition heat conduction layer formed by the heat conduction membrane 2 has a strong liquid locking function, and can effectively prevent the aerosol forming substrate from seeping out of the transition heat conduction layer to generate liquid leakage. In addition, the thickness of the transition heat conduction layer formed by the heat conduction membrane 2 is thinner, the phenomenon that the atomizing core is dried and burnt due to the fact that the aerosol forming substrate with high viscosity and poor flowability cannot permeate the atomizing surface 4 in time is effectively avoided, the aerosol forming substrate can be preheated before the aerosol forming substrate permeates the atomizing surface 4, the phenomenon that oil frying occurs due to the fact that the aerosol forming substrate is directly heated to high temperature instantly at normal temperature is prevented, the heat capacity of the transition heat conduction layer (the heat conduction membrane 2) can be reduced, and the heating efficiency of the heating element 3 to the aerosol forming substrate is effectively improved.

Of course, it is understood that in other embodiments, the outline of the porous substrate 1 may be other polyhedral shapes such as a cylinder, an ellipse, etc., and the shape and size of the heat-conducting membrane 2 are adapted to at least one side surface of the porous substrate 1.
In some embodiments, the porous substrate 1 is a porous ceramic member, which has excellent characteristics of chemical stability, high temperature resistance, good insulating property, and the like, and does not chemically react with the aerosol-forming substrate, and thus the porous substrate 1 is made of porous ceramic. Wherein, in some embodiments, the porous ceramic member includes, but is not limited to, alumina, zirconia, silicon carbide, silicon nitride, and the porosity of the porous ceramic member is 45% to 55%. It will be appreciated that the above-mentioned physical parameters of the porous ceramic element may be suitably adjusted according to the composition of the aerosol-forming substrate or the specific requirements of use. So, only need to cover at the atomizing face 4 of porous ceramic spare and establish film formula transition heat-conducting layer, just can transmit the atomizing face 4 to the heat that the piece 3 produced that will generate heat through transition heat-conducting layer fast evenly for heat evenly distributed is on whole atomizing face 4, and then makes aerosol formation substrate be heated evenly, effectively avoids atomizing core's atomizing face 4 to appear the phenomenon of dry combustion method because of local temperature is too high. In this process, because the heated area increase of aerosol formation matrix, and aerosol formation matrix can be at the even heating of whole atomising face 4, both can make the atomizing core have good atomization effect, promote user's taste, can avoid again that the particulate matter in the aerosol formation matrix blocks up the hole of porous base member 1, reduces the carbon deposit volume of atomizing core in the atomization process. It is understood that in other embodiments, the porous matrix 1 may be made of porous glass material with a microporous structure.
In some embodiments, the heating element 3 may be, but is not limited to, an electric heating wire made of silver, palladium alloy, or iron, nickel, chromium alloy, etc., and formed on the atomizing surface 4 in a thick film manner.
