Optionally, the porosity of the porous material is greater than 50%, and the proportion of open pores in the pores of the porous material is greater than 50%. If the porosity is too low, sufficient liquid smoking material cannot be adsorbed, and the closed pores cannot release aerosol from the outside to the filler in the porous material. Only enough open air holes exist, enough liquid smoking substances can be adsorbed in the air holes, and aerosol generated by heating the liquid smoking substances can be released smoothly.
Alternatively, referring to fig. 2, the heating element 12 is disposed on the inner surface of the body 11.
For example, the porous material comprises a porous ceramic and the heating element 12 comprises a heating wire or a patterned metal paste. For example, a heating wire is fixed to the inner surface of the porous material formed from the main body 11, or a patterned metal paste is fixed to the inner surface of the main body 11.
In one particular example, the porous ceramic comprises a porous alumina ceramic and the metal slurry comprises a tungsten slurry.

For example, the porous alloy includes a porous iron-aluminum alloy.
In this embodiment, the heating wire is combined with the porous alloy through high temperature, thereby realizing the fixed connection of the two.
It should be noted that the embodiment of the present application may be applied as long as the porous material is resistant to high temperature and can achieve good fixed connection with the heating element 12. For example, the heating element 12 may also be an infrared coating around the body 11, the infrared coating being provided on the inner surface of the carrier around the body 11. In this way, infrared radiation from the infrared coating may heat both the liquid smoking substance within the porous material and the solid substance surrounded by the body 11. If the infrared attenuation is too high, a needle-shaped or column-shaped heating element 12 may be further disposed in the space enclosed by the body 11. I.e., the heating element 12, may be a multi-component or multi-component, as long as good heating of the liquid smoking material and the solid material is achieved.

Also for example, the smoking material is a non-combustible heat tobacco rod, which typically has a smoking section, a cooling section and a filter section arranged in series. The outer wall of the main body 11 can be wrapped by the air outlet pipeline, the air outlet pipeline is sealed above the smoking section of the cigarette which is not burnt by heating, and the aerosol volatilized in the porous material can only be discharged from the smoking section of the cigarette which is not burnt by heating to heat the non-combustible device, so that the fusion of the two aerosols is realized.
Of course, the manner in which the fusion of the two aerosols is achieved is not limited thereto.

Namely, an oil storage pump is arranged in the heating non-combustion device, and liquid smokeable materials such as tobacco tar or liquid essence are stored in the oil storage pump. For example, the outer wall of the porous material is perforated (not through holes) and the outlet of the oil reservoir pump is inserted into the holes. When the tobacco tar needs to be added, the tobacco tar is injected into the porous material through the oil storage pump, so that the filler can be realized.
Of course, the manner of realizing the filler in the porous material is not limited thereto, and for example, the outer wall of the porous material may be partially or entirely soaked in the tobacco tar.
