Abstract: This disclosure provides an atomizer and an aerosol generating device. The atomizer includes a liquid storage cavity, an atomizing cavity, a pressure relief channel, and a heating element. The liquid storage cavity includes at least two liquid storage sub-cavities that are sequentially spaced. The bottoms of two adjacent liquid storage sub-cavities are in communication with each other through a connection groove. An inlet of the pressure relief channel is in communication with one of the liquid storage sub-cavities. An outlet of the pressure relief channel is in communication with the atomizing cavity. A liquid inlet surface of the heating element is in communication with each of the liquid storage sub-cavities. An atomizing surface of the heating element is in communication with the atomizing cavity.

Abstract: An atomization assembly and an electronic atomization device are provided. The atomization assembly includes a liquid storage cavity is configured to store an atomizing medium. A liquid opening is communicated with a bottom portion of the liquid storage cavity. At least one vent channel includes a first port and a second port. The first port is in communication with the liquid storage cavity, and the second port is in communication with an outside atmosphere. A blocking member is arranged in the liquid storage cavity and located on a side of the second port facing the liquid feeding opening. The blocking member minimizing air bubbles flowing from the second port to the liquid opening.

Abstract: An atomizer includes: a liquid storage body having a liquid storage cavity and an air outlet channel formed therein; a base at least partially embedded in the liquid storage body; a heating component arranged in the base; a first electrode connector arranged in the liquid storage body and being in contact with and in communication with the heating component; and a second electrode connector insulatedly arranged to extend through the base and being in contact with and in communication with the heating component. A liquid flowing channel for bringing the heating component into communication with the liquid storage cavity and an air outlet hole for bringing the heating component into communication with the air outlet channel are formed on the first electrode connector.

Abstract: A vaporizer includes: a vaporization cartridge having: a cartridge tube provided with a liquid storage cavity; and a vaporization assembly inserted in the cartridge tube, a part of the vaporization assembly being located in the liquid storage cavity, a first end of the vaporization assembly being in communication with an outside, a second end of the vaporization assembly being provided with a connection portion, a mouthpiece component, the vaporization cartridge being mounted in the mouthpiece component so as to enable aerosols generated by the vaporization cartridge to flow out through the mouthpiece component; and a connector separately fitted to the connection portion and the mouthpiece component so as to enable the vaporization cartridge to be mounted in the mouthpiece component.
