  • Heat transfer efficiency of heat convection is lower than heat transfer efficiency of heat conduction, and therefore, a heat transfer rate of the heat from the heating member 19 to the outer periphery of the aerosol-generating substrate 11 is effectively slowed down. Therefore, the heat transfer rate of the heating member 19 to the outer periphery of the aerosol-generating substrate 11 is close to the heat transfer rate of the outer periphery of the aerosol-generating substrate 11 to the inside of the aerosol-generating substrate 11.
  • the temperature difference between the inner and outer periphery of the aerosol-generating substrate 11 is effectively reduced, thereby resolving the problem of uneven temperature between the inner and outer periphery of the aerosol-generating substrate 11 during heating.

  • the heat transfer rate of the heat to the outer periphery of the aerosol-generating substrate 11 is slower, the temperature difference between the outer periphery of the aerosol-generating substrate 11 and the inside of the aerosol-generating substrate 11 is smaller, and uniformity of temperature distribution between the inner periphery and the outer periphery of the aerosol-generating substrate 11 is better, thereby resolving the problem of uneven temperature between the inner and outer periphery of the aerosol-generating substrate during heating.
  • the housing 12 of the aerosol-generating device 10 is able to be insulated.
  • first airflow channel 21 and the second airflow channel 20 are disposed on two sides of the heating member 19, such that flow of the airflow in the heating cavity 173 is able to be increased, and the airflow may simultaneously flow from two sides of the first sidewall 191. Therefore, inhalation resistance inside the aerosol-generating device 10 is smaller, and the user inhales more easily when using the aerosol-generating device 10.
  • the protrusion 193 is able to further reduce a contact area between the heating member 19 and the aerosol-generating substrate 11, and an aerosol condensate is less likely to adhere to the first sidewall 191, thereby reducing adhesion of stains on the heating member 19.
  • the arrangement of the protrusion 193 is also able to reduce a contact area between the heating member 19 and the paper outer wall, so as to prevent the paper outer wall from being baked and pasted due to overheating, and prevent a pungent smell from forming, which improves user experience.

  • the heat transfer rate inside the aerosol-generating substrate 11 is greater than the heat transfer rate between the heating member 19 and the outer periphery of the aerosol-generating substrate 11, and the temperature difference between the inside and outside of the aerosol-generating substrate 11 tends to be 0 after heating for a period of time, and the inner and outer periphery temperature are more evenly distributed.
  • the area ratio of the contact surface to the inner surface of the first sidewall 191 may not be too high or too low, and when the area ratio is too high, the proportion of heat convection in the common heat transfer manner is reduced, and the heat transfer rate of the heat to the aerosol-generating substrate 11 is not able to be reduced. Too low an area ratio makes the proportion of heat conduction too low and the heating effect is not good.
  • the protrusion 193 may be a bump, and the bump is disposed on the inner surface of the first sidewall 191.

  • the bump may alternatively be made of a material different from the material of the first sidewall 191, and the bump may be made of a material with relatively poor heat conductivity. Therefore, when the heat is transferred from the protrusion 193 to the aerosol-generating substrate 11 in the heat conduction manner, As heat conductivity of the bump is relatively poor, the speed of heat conduction may be reduced, such that the heat transfer rate of the heating member 19 to the outer periphery of the aerosol-generating substrate 11 and the heat transfer rate of the outer periphery of the aerosol-generating substrate 11 to the inside of the aerosol-generating substrate 11 are closer to each other. Therefore, the temperature difference between the inner and outer periphery of the aerosol-generating substrate 11 is effectively reduced, and the temperature of the inner and outer periphery of the aerosol-generating substrate 11 is more uniform.
  • the maximum height of the protrusion 193 is 2 mm-5 mm.
  • the maximum height of the protrusion 193 refers to the maximum height at which the protrusion 193 protrudes relative to the inner surface of the first sidewall 191.
  • the maximum height of the protrusion 193 may be adjusted to adjust the width of the gap between the heating member 19 and the aerosol-generating substrate 11, so as to control the size of the airflow in the second airflow channel 20, thereby achieving the effect of adjusting the inhalation resistance.
