The invention discloses a control method based on an adaptive temperature circuit in a heated unburnt cigarette. The method comprises the following steps: both a first electrically-controlled switch and a second electrically-controlled switch are set to alternately work by taking t as a cycle; a temperature value of heating wires of a current cycle is calculated through heating time of each cycle,and heating time of the heating wires of next cycle is adjusted by taking a set value as a standard; an MCU monitors the heating time of each cycle and the temperature value of the heating wires of the current cycle in real time and judges a number of times of smoking and whether smoking is performed or not; when the number of times of smoking is equal to a set number of times, the MCU controls and adjusts a set temperature to perform heating-up treatment in each cycle, where each subsequent smoking presents. According to the method, temperature control on heating wires is carried out througha temperature control method for time-sharing processing of the heating wires in the unburnt cigarette, and the number of times of smoking can be automatically monitored during smoking of a person, so that the problem that the smoke concentration of the heating wires in the unburnt cigarette is lowered along with the increase of number of times of smoking can be solved.
