Method for controlling the output power of a power supply of electronic cigarette and electronic cigarette

An electronic cigarette comprising a controller, wherein the controller comprises a processor and a memory communicatively connected to the processor;

• program instructions are stored in the memory;
• and the processor is capable of implementing, by executing the program instructions, a method for controlling output power of a power supply of an electronic cigarette comprising:
• S1:
• when inhalation airflow is first detected, controlling the power supply to output a first power P1 to a heating element in a first time period T1 in a first inhalation airflow flowing process, and to output a second power P2 to the heating element in a second time period T2 immediately following the first time period T1 in the first inhalation airflow flowing process, wherein P1>P2, and when flowing of the first inhalation airflow ends or when the power supply continuously outputs power for a time period greater than a first threshold TM, controlling the power supply to stop outputting power to the heating element;
• and
• S2:
• continuously detecting the inhalation airflow;
• and
• if a time interval between a time at which the inhalation airflow is detected and a time at which the power supply previously stops outputting power to the heating element is less than or equal to a second threshold TN, controlling the power supply to output a third power P3 to the heating element in the inhalation airflow flowing process, wherein P1>P3;
• or
• if a time interval between a time at which the inhalation airflow is detected and a time at which the power supply previously stops outputting power to the heating element is greater than the second threshold TN, controlling the power supply to output the first power P1 to the heating element in the first time period T1 in the inhalation airflow flowing process, and to output the second power P2 to the heating element in the second time period T2 immediately following the first time period T1 in the inhalation airflow flowing process, wherein P1>P2, and when flowing of the inhalation airflow ends or when the power supply continuously outputs power for a time period greater than the first threshold TM, controlling the power supply to stop outputting power to the heating element.
