Abstract: An electronic cigarette control method and an electronic cigarette are provided. The method includes: acquiring the characteristic parameter of the atomizer of the electronic cigarette; determining the first output power corresponding to the characteristic parameter of the atomizer; and outputting electric energy to the atomizer with the first output power when a smoking signal is detected. The electronic cigarette can output electric energy of different powers to atomizers with different specifications, so that the battery device of the electronic cigarette can be adapted to atomizers with different specifications, thereby increasing the adaptation range of the electronic cigarette.

Abstract: A liquid supply device for supplying liquid to an atomizing device is provided. The liquid supply device includes a liquid supply member and a connecting member. An inner space of the liquid supply member is a liquid supply chamber containing cigarette liquid. The liquid supply member is provided with a connecting hole. Opposite ends of the connecting member are a liquid inlet end and a liquid outlet end. The liquid inlet end is connected to the connecting hole. An interior of the connecting member is a liquid outlet passage. A control valve is provided on the connecting member. When the atomizing device is installed to the liquid outlet end, by operating the control valve, the liquid outlet passage communicates the liquid supply chamber with the liquid storage chamber, or the liquid supply chamber and the liquid storage chamber are cut off by the control valve.

Abstract: An electronic cigarette control method and an electronic cigarette. The control method comprises: obtaining characteristic parameters of an atomizer of the electronic cigarette (110); determining a first output power corresponding to the characteristic parameters of the atomizer; and when a cigarette lighter signal is received, outputting electric energy to the atomizer according to the first output power. The electronic cigarette (110) can output electric energy of different powers to the atomizers with different specifications, so that the electronic cigarette (110) can be adapted to battery devices with different specifications, thereby increasing the adaptation range of the electronic cigarette (110).
