This application relates to the technical field of atomization devices, and particularly discloses a liquid reservoir and an electronic atomization device. The liquid reservoir includes a housing assembly, and a cover assembly is at least partially disposed in the housing assembly. The cover assembly can move between a first position and a second position relative to the housing assembly. At least a portion of the cover assembly and the housing assembly jointly define an accommodating space, and the accommodating space is used for accommodating a liquid substrate. A liquid outlet hole is configured to provide a liquid outlet through which the liquid substrate overflows from the liquid reservoir. When the cover assembly moves to the first position, the cover assembly blocks the liquid outlet hole. When the cover assembly moves to the second position, the cover assembly compresses a volume of the accommodating space to drive the liquid substrate to enter the liquid outlet hole and then be discharged. In the foregoing manner, in an embodiment of this application, when the liquid reservoir is assembled to an atomizer, the cover assembly compresses the volume of the accommodating space to squeeze part of the liquid substrate into the atomizer, so that the atomizer can be used immediately for inhalation upon completion of assembly without waiting.

This application relates to an aerosol-generating device, including: a suction nozzle module, including a first connection component; an atomization module, including a plurality of atomization cores and a plurality of storage cavities for storing an aerosol-generating substrate, where each of the storage cavities is correspondingly in communication with at least one of the atomization cores, to provide the aerosol-generating substrate for the atomization core for atomization to generate an aerosol; and a power supply module, configured to be capable of rotating relative to the atomization module, where a second connection component is connected to the first connection component, where an interference structure is disposed on the first connection component and/or the second connection component, a connection between the first connection component and the second connection component has an unlocked state and a locked state, and the first connection component and the second connection component keep connected in both the unlocked state and the locked state; and the first connection component and the second connection component are capable of keeping relative rotation in the unlocked state, and rotation between the first connection component and the second connection component is restricted in the locked state by the interference structure.

A liquid storage component, an atomization assembly, and an electronic atomization apparatus are provided. The atomization assembly includes: a first housing forming a first liquid storage cavity; and a second housing, independent of but connectable to the first housing, with a second liquid storage cavity configured to store a liquid substrate. A connection channel is provided between the first and second liquid storage cavities to link the cavities. An atomization core on the second housing is in fluid communication with the second liquid storage cavity. A movable member connected to the first housing is movable relative to the first housing from a first position to a second position. As the movable member moves, volume of the first liquid storage cavity can be compressed, pushing the liquid substrate stored in the first liquid storage cavity to flow into the second liquid storage cavity via the connection channel.

A device body and an electronic atomization device are provided, including a first housing with a first liquid storage cavity; an atomization core disposed in the first housing; and a second housing, independent of the first housing and with a second liquid storage cavity for storing a liquid substrate. The second housing is connectable to the first housing, establishing a connection channel between the two cavities for flow of liquid substrate and/or air. The connection channel includes a first section adjacent to and in communication with the second cavity and at least one second section in communication with the first section. The second section is adjacent to and in communication with the first cavity. The cross-sectional area of the first section is greater than that of the second section. This design allows air bubbles in the connection channel to be easily removed, preventing from blockage and ensuring timely liquid supply.
