• the quantity of air holes 111a is less than 1, the flowing resistance inside the monomer 11 is high, leading to the high inhalation resistance, so that it is difficult to extract the aerosol in the monomer 11, and the aerosol utilization rate is reduced.
• the quantity of air holes 111a is greater than 730, the wall between two adjacent air holes 111a is too thin, so that the medium quality of the monomer 11 is low, and the aerosol release time is too short. Thus, the heat can be easily dispersed or diffused, and a burning phenomenon easily occurs.
• non-uniform release of the aerosol easily occurs in the heating process, such as a non-uniform release phenomenon: in the inhalation process, the release amount of the aerosol is large in the previous two instances of inhalation and the release amount of the aerosol is small in the later instances of inhalation.

In this design, the structural strength of the monomer 11 is good, which can stably maintain the overall shape. This can not only balance the flowing resistance of the aerosol and the overall quality and heating uniformity of the monomer 11, but also reduce the burning phenomenon and the non-uniform aerosol release phenomenon, thereby enhancing the inhalation experience of a user.
• 9 to 60 air holes 111a are formed in a single monomer 11. In this way, the wall between two adjacent air holes 111a has a moderate thickness; the manufacturing difficulty of the monomer 11 is moderate; the collapse of the air holes 111a during the manufacturing is avoided; and the product yield is improved.

• the quantity of monomers 11 is between 2 and 20. Since the size of the aerosol generating substrate 10 is limited, a larger quantity of monomers 11 indicates the smaller size of each monomer 11, a more complex process, higher manufacturing difficulty, and higher costs. When the quantity of monomers 11 is greater than 30, the size of each monomer 11 is excessively small, so that the production efficiency is excessively low, and costs are excessively high. If the quantity of monomers 11 is between 2 and 30, the difficulty of manufacturing the monomers 11 is low, and the product yield is high.
