[0036] The aerosol production device generally utilizes an atomizer 100 to atomize an aerosol substrate to form an aerosol. The atomizer 100 is generally provided with an oil storage cavity 101 for storing the aerosol substrate. The atomizer 100 generally adds the aerosol substrate to the oil storage cavity 101 through an oil injection hole 201, so that the aerosol substrate is stored in the oil storage cavity 101 of the atomizer 100.

[0037] However, during the process of adding the aerosol substrate to the oil storage cavity 101, the aerosol substrate gradually occupies the space of the oil storage cavity 101, so that the air pressure in the oil storage cavity 101 becomes larger, which hinders the addition of the aerosol substrate to the oil storage cavity 101, causing the atomizer 100 to be inconvenient to use.

[0038] Please refer to Figure 1 and Figure 2 To solve the above technical problems, the present application provides an aerosol generating device, which comprises an atomizer 100 for atomizing an aerosol substrate to form an aerosol.

[0045] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 The first seal 40 can move between a first position and a second position. When the first seal 40 is in the first position, the first seal 40 blocks the first hole section 2011 and the second hole section 2012. When the first seal 40 is in the second position, the first seal 40 blocks the second hole section 2012, and the first hole section 2011 communicates the oil storage cavity 101 and the oil guide channel 204.

The second seal 50 can move between a third position and a fourth position. When the second seal 50 is in the third position, the second seal 50 blocks the third hole section 2021 and the fourth hole section 2022. When the second seal 50 is in the fourth position, the second seal 50 blocks the fourth hole section 2022, and the third hole section 2021 communicates the oil storage cavity 101 and the oil guide channel 204.
