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.
