摘要： Disclosed is an atomizer and an aerosol generation device with the atomizer. The atomizer includes a liquid storage member, an atomizing assembly and a mouthpiece. A liquid storage chamber is formed in the liquid storage member. The atomizing assembly is mounted on the liquid storage member. The atomizing assembly is provided with an atomizing chamber and a liquid inlet which is in communication with the atomizing chamber. The mouthpiece is slidably sleeved on the outside of the atomizing assembly. The mouthpiece can slide between a first locking position and a second locking position relative to the liquid storage member. When the mouthpiece slides to the first locking position, the mouthpiece closes the liquid inlet; and when the mouthpiece slides from the first locking position to the second locking position, the mouthpiece opens the liquid inlet, such that the liquid inlet is in communication with the liquid storage chamber.

摘要： The utility model provided an atomizer. The atomizer includes an atomizing head defining an atomizing chamber; and a base seat assembly positioned on an end of the atomizing head. The base seat includes a base seat defining a liquid storage groove in communication with the atomizing chamber. The liquid storage groove is provided with a convex body defining at least one ventilation hole, when the tobacco liquid explodes, the tobacco liquid splashes to the convex body and capable of flowing into the liquid storage groove along the convex body. In the atomizer of the utility model, the tobacco liquid is prevented from leaking through the ventilation hole. It has a simple structure and a notable effect, and lightens the clear-up workload of the user, thereby improving user's experience. The utility model further provides an electronic cigarette having aforementioned atomizer.

摘要： 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.
