Abstract: A cartridge includes a cartridge casing with a liquid storage chamber therein, a sealing member for sealing the liquid storage chamber, a shielding member provided on the cartridge casing, an atomizing chamber, a smoke outlet channel and an air inlet passage. The sealing member is located between the shielding member and the cartridge casing. The shielding member forms part of the outer contour of the cartridge and the sealing member is shielded by the shielding member. A communication opening is defined through the shielding member. The sealing member is an elastically deformable member. When filling liquid, a liquid injection needle passes through the communication opening and pierces the sealing member, and then extends into the liquid storage chamber to inject e-liquid. When the liquid injection needle is pulled out after liquid injection, the sealing member automatically restores to seal the liquid storage chamber again.

Abstract: An electronic cigarette control method, an electronic cigarette control device and an electronic cigarette using the control method and the control device are provided. The control method includes: determining the suction force indication information according to the information detected by a detecting assembly, wherein the detecting assembly includes a first air pressure detecting member arranged in an air passage in communication with a mouthpiece; determining the target value of a working parameter of an atomizer according to the suction force indication information, wherein the working parameter includes at least one of the output power, the temperature in an atomizing chamber, the working voltage of the atomizer, and the temperature of a heating member; and controlling the atomizer to work according to the target value of the working parameter. The control method can adjust the output power, so that the user can obtain different smoking tastes.
