Abstract: A control method and device, and an electronic cigarette. The method includes: obtaining the maximum output power during the secure output of an atomizer connected to a body; detecting whether the currently-set target power of the atomizer is higher than the maximum output power; and if the target power is higher than the maximum output power, executing a preset operation, the preset operation including at least one of controlling, the atomizer to output at power lower than or equal to the maximum output power and displaying a first reminder message, according to a cigarette lighting signal. The method resolves the problem that dry burning would easily occur in an atomizer, and has the function of protecting the atomizer and preventing the shortening of the life of a heating component caused by the burning of the heating component due to high power output of the atomizer.

Abstract: An electronic cigarette control method applied to an electronic cigarette is provided. The method includes: when it is detected that an atomizer starts to work, detecting whether the working state of the atomizer meets a preset condition, wherein the atomizer is configured to atomize an aerosol-forming substrate in the electronic cigarette, and the preset condition includes: the working time of the atomizer reaches a first preset duration, or the number of times the atomizer works within a preset time period is greater than or equal to a preset number of working times; and if the working state of the atomizer meets the preset condition, controlling the atomizer to stop working.

Abstract: A method for obtaining the intake quantity of a target substance and an electronic device. The method includes: obtaining consumption information of a carrier within a statistical period, the consumption information including at least one of a first consumption quantity of the carrier within the statistical period, a second consumption quantity of the carrier within a valid time period during a single intake, and a third consumption quantity of the carrier within each unit time period in the valid time period; and obtaining the intake quantity of the target substance within the statistical period according to the consumption information and the content of the target substance in the carrier. The present invention has a reference effect during smoking quitting of a user by using an electronic cigarette, and can help the user actively stop smoking.
