摘要： An atomizer and an aerosol generating device. In the atomizer, an atomizing housing (1) is at least partially accommodated in a liquid storage cavity (53), a liquid storage space is formed in the atomizing housing (1), and a pressure relief hole (114) in communication with the liquid storage space and the liquid storage cavity (53) and an air guide port (117) for communicating the liquid storage space with the outside atmosphere are provided on the atomizing housing (1). In this way, when the air pressure in the liquid storage cavity (53) is greater than the external air pressure and a positive pressure difference is formed, the positive pressure difference presses an aerosol-forming substrate in the liquid storage cavity (53) into the liquid storage space by means of the pressure relief hole (114), so that the internal air pressure of the atomizer and the external air pressure reach a balanced state. However, when the air pressure in the liquid storage cavity (53) is greater than the external air pressure and a negative pressure difference is formed, the negative pressure difference presses an aerosol-forming substrate in the liquid storage space back into the liquid storage cavity (53) by means of the pressure relief hole (114), so that the internal air pressure of the atomizer and the external air pressure reach a balanced state. In this process, the aerosol-forming substrate is prevented from flowing into an atomizing cavity (112), thereby avoiding seepage of the aerosol-forming substrate, and effectively preventing liquid leakage of the atomizer.

摘要： This application discloses a vaporizer and an aerosol generation device. The vaporizer includes a housing provided with an open end, where a liquid storage cavity and a vaporization component for vaporizing a liquid substrate to form an aerosol are provided in the housing; a base, covering the open end of the housing, where at least a part of the base defines an air inlet for entry of external air, at least a part of the air inlet extends transversely in a short axis direction of the housing, and the base and the vaporization component jointly define a vaporization cavity; and at least one first airflow channel, connecting the air inlet to the vaporization cavity, where at least a part of the first airflow channel extends longitudinally along the housing. In the foregoing vaporizer, since at least a part of the air inlet extends transversely along the housing, then enters the longitudinally extending first airflow channel, and then enters the vaporization cavity, a liquid in the vaporization cavity cannot enter the air inlet and cannot leak to the outside of the vaporizer.

摘要： An atomizer and an aerosol generating device. An atomizing assembly (2) and a sealing base (3) are provided in an accommodating cavity of a liquid storage member (1), and the atomizing assembly (2) is supported on the sealing base (3), so that the portion of the interior of the liquid storage member (1) other than the atomizing assembly (2) and the sealing base (3) defines a liquid storage cavity (5), and an atomization cavity (6) is provided inside the atomization assembly (2). The liquid storage cavity (5) is communicated with the atomization cavity (6) by means of a liquid inlet hole (211). An air inlet hole (121) is formed on the liquid storage member (1), and an air inlet channel (31) that communicates the atomization cavity (6) with the air inlet hole (121) is formed on the sealing base (3). During transportation or before sale of the aerosol generating device, only by sealing the air inlet channel (31) by means of a plugging assembly (4) to block the communication between the atomizing cavity (6) and the air inlet hole (121), the aerosol-forming substrate stored in the liquid storage cavity (5) can be effectively prevented from leaking through the air inlet hole (121), thereby avoiding pollution and waste caused by liquid leakage and short-circuit damage to electronic components in a battery.
