A control method for an aerosol-generating device, including: detecting whether an aerosol-generating device is in a suction state (S 110 ); detecting a child-lock state of the aerosol generating device (S 120 ); determining whether the number of suctions of the aerosol generating device within a first preset time period is greater than a first threshold (S 130 ); enabling the aerosol generating device to be in a child-lock closed state (S 140 ); determining whether the single atomization time of the aerosol generating device is greater than a second time threshold (S 150 ); and the aerosol generating device stopping atomization (S 160 ). By integrating a child-lock on an airflow sensor of the aerosol generating device, the aerosol generating device can prevent children from accidental suction; moreover, without increasing costs or adding complex structural members, the original technical design is maintained, and a child-lock function is added, thereby preventing children from accidental use, and greatly reducing the manufacturing cost.

A cartridge includes a cartridge housing having a liquid storage cavity, and a sealing member for sealing the liquid storage cavity, and a first electrode and a second electrode mounted on the sealing member. A first blind hole and a second blind hole are respectively disposed on the end face of the sealing member away from the liquid storage cavity. The liquid injection needle pierces the sealing member through the wall of at least one of the first blind hole and the second blind hole and communicates with the liquid storage cavity to inject liquid into the liquid storage cavity. After the liquid injection is completed, the liquid injection needle is pulled out, and the sealing member is self-sealed at the pierced position. The first blind hole is blocked by the first electrode while the second blind hole is blocked by the second electrode.

Disclosed are a cartridge and an electronic cigarette having the cartridge. The cartridge includes a liquid storage cavity, an atomizing cavity, a liquid suction member, a liquid outlet, a smoke outlet, and an air inlet opening. Before the cartridge is used, the liquid outlet is in a closed state, such that e-liquid in the liquid storage cavity is isolated from the liquid suction member. When the cartridge is used, the liquid outlet is in an open state, such that the e-liquid in the liquid storage cavity flows out through the liquid outlet. The atomizing cavity is provided with an opening, and the size of the heating member matches the size of the opening; and when the cartridge is used, the heating member extends into the atomizing cavity through the opening and comes into contact with the liquid suction member or stays a preset distance away from the liquid suction member.
