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： An atomizer (100) comprises a liquid storage member (10) and an atomization assembly (20). A liquid storage cavity (101) used to store an aerosol formation matrix is provided on the liquid storage member (10). The atomization assembly (20) is slidably connected to the liquid storage member (10), and comprises a heat generation structure (21) used to heat the aerosol formation matrix. The atomization assembly (20) is provided with a liquid inlet (202). A sealing member (30) is installed on the liquid inlet (202). An upper rod (40) is fixedly provided within and opposing the liquid storage member (10), and is connected to the sealing member (30). Sliding the atomization assembly (20) relative to the liquid storage member (10) enables the atomization assembly (20) to move between a first position and a second position. When the atomization assembly (20) is in the first position, the sealing member (30) closes the liquid inlet (202), and when the atomization assembly (20) is in the second position, the sealing member (30) is separated from the liquid inlet (202). The aerosol formation matrix passes through the liquid inlet (202) and comes into contact with the heat generation structure (21). In the atomizer (100), the aerosol formation matrix is separable from the heat generation structure (21), thereby preventing leakage and deterioration. Further disclosed is an aerosol generation device having the atomizer (100).
