Abstract: Disclosed are an atomizer and an aerosol generating device with the atomizer. The atomizer includes a liquid storage member, an air guiding member and a bottom seat arranged between the liquid storage member and the air guiding member, wherein an atomizing chamber is provided in the atomizer, an air guiding groove in communication with the atomizing chamber is provided on the liquid storage member, and an air inlet channel in communication with the air guiding groove is provided on the air guiding member.

Abstract: 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.
