[0031] Embodiment 1

[0032] As Figures 1-8 shown, the present application provides an aerosol generating device, which comprises a nozzle assembly 1 and a liquid storage assembly 2 that are rotationally screwed to each other. The nozzle assembly 1 is provided with a switching channel 11. The nozzle assembly 1 has an air outlet inner hole 12. The first end of the switching channel 11 is in communication with the air outlet inner hole 12. The second end of the switching channel 11 extends to the end of the nozzle assembly 1 facing the liquid storage assembly 2. The end of the liquid storage assembly 2 facing the nozzle assembly 1 is provided with a liquid injection hole 221. When the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to a first position, the liquid injection state is achieved, in which the switching channel 11 is in communication with the liquid injection hole 221. When the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to a second position, the liquid injection plugging state is achieved, in which the switching channel 11 is disconnected from the liquid injection hole 221.

[0033] In the embodiment, the aerosol generating device comprises a nozzle assembly 1 and a liquid storage assembly 2 that are rotationally engaged with each other. The nozzle assembly 1 is provided with a conversion channel 11. The nozzle assembly 1 has an air outlet inner hole 12. The first end of the conversion channel 11 is in communication with the air outlet inner hole 12. The second end of the conversion channel 11 extends to the end of the nozzle assembly 1 that faces the liquid storage assembly 2. The end of the liquid storage assembly 2 that faces the nozzle assembly 1 is provided with a liquid injection hole 221. The liquid injection hole 221 is used to add atomized liquid to the atomized liquid storage cavity in the liquid storage assembly 2. When the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to a first position, the liquid injection state is achieved, in which the conversion channel 11 is in communication with the liquid injection hole 221. When the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to a second position, the liquid injection plugging state is achieved, in which the conversion channel 11 is disconnected from the liquid injection hole 221. Specifically, when the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to the first position, the conversion channel 11 is rotated to a position in communication with the liquid injection hole 221. At this time, the liquid injection pipe of the liquid injection pot can be inserted into the conversion channel 11 through the air outlet inner hole 12 of the nozzle assembly 1 to add atomized liquid to the liquid storage assembly 2. Compared with the current liquid injection method of the liquid storage assembly 2, in which the liquid injection hole 221 is opened on the outside and atomized liquid is added to the liquid storage assembly 2 through the liquid injection hole 221, and the liquid injection hole 221 is covered with a rubber plug or a cover after the addition, the external liquid injection hole 221 is hidden, and there is a clear blocking feature, good concealment, and improved product appearance. When the nozzle assembly 1 and the liquid storage assembly 2 are relatively rotated to the second position, which can be any position other than the first position, the conversion channel 11 is disconnected from the liquid injection hole 221 because the conversion channel 11 is rotated to a position offset from the liquid injection hole 221, thereby preventing liquid leakage. Therefore, the aerosol generating device of the present application realizes hidden liquid injection, does not need to remove the nozzle assembly 1 from the top of the liquid storage assembly 2, does not leak liquid, and can improve user experience.

The first end of the gas guide pipe 3 is in communication with the air outlet inner hole 12. The second end of the gas guide pipe 3 is in communication with the atomizing core 4.
