The disclosures of the above-referenced applications are hereby incorporated by reference in their entireties. BACKGROUND The aerosol generating substrate may form an aerosol by ignition or form an aerosol by heating without combustion. Taking an aerosol generating substrate that is heated without combustion as an example, the aerosol generating substrate is heated by an external heat source, so that the aerosol generating substrate is heated just enough to generate an aerosol, the aerosol generating substrate will not burn, and the aerosol is released by heating the aerosol generating substrate in use. In the related art, the density of the substancial substrate of the aerosol generating substrate is high, which leads to the fact that the aerosol cannot be released in time, and the extraction efficiency of the aerosol is greatly reduced.

DETAILED DESCRIPTION It should be noted that embodiments and features in the embodiments of the present disclosure may be combined with each other without conflict, and the detailed description should be understood as an explanation of the present disclosure and should not be regarded as an undue limitation of the present disclosure. In the present disclosure, the plurality includes two or more. The unit “mm” is millimeters.
