  • the embodiment of the invention provides a e-liquid supply method, using the relation of temperature and e-liquid amount to supply specific amount of e-liquid. It should be understood that the e-liquid of the embodiment of the present invention is an aerosol forming matrix; the e-liquid is not a certain tobacco product or tobacco product.
  • the e-liquid supply method includes the following steps: Step S110: obtaining the real-time temperature of the heating member of the aerosol generating device every first preset period after lighting a cigarette.
  • the first preset period should not be too long, otherwise the real-time temperature of the heating member cannot be more accurately reflected.
  • the first preset period is 10ms, the real-time temperature of the heating member is obtained every 10ms, which can not only reflect the real-time temperature but also improve the efficiency.

  • the real-time temperature of the heating member obtained for the first time is the initial temperature. That is, the real-time temperature corresponding to the first preset period after lighting the cigarette is the initial temperature. Therefore, the real-time temperature change value is the difference between each real-time temperature and the initial temperature. It should also be understood that since the real-time temperature is acquired every first preset period, the real-time temperature change value is also acquired every first preset period. The time length of the second preset period is greater than the time length of the first preset period.
