[0032] Please refer to Figures 1 to 3, the aerosol generating device 1 provided by the first embodiment of the present utility model includes a detachable atomizer module 10 and a battery module 11. The atomizer module 10 includes a housing 100, a mouthpiece 101 extending from one side of the housing 100, an atomization assembly 103 disposed in the housing 100, and an air intake bracket 104. The air intake bracket 104 is disposed on the side of the atomization assembly 103 away from the mouthpiece 101. The air intake bracket 104 includes a main body portion 1040 and an air intake passage 1047. The main body portion 1040 includes a bottom plate 1041 and a surrounding plate 1042 disposed on the bottom plate 1041. An air intake space 1043 is defined within the surrounding plate 1042. The air intake passage 1047 communicates with the air intake space 1043 and extends in a direction away from the atomization assembly 103. Air holes 1045 are formed in the side wall of the surrounding plate 1042. The air holes 1045 are spaced apart from the bottom plate 1041. A microphone 1007 is provided on the side of the air holes 1045 away from the air intake space 1043. There is a gap between the air holes 1045 and the bottom plate 1041, such that a height difference is formed between the air holes 1045 and the bottom plate 1041. The condensate entering through the air intake passage 1047 will preferentially fall on the bottom plate 1041 and be blocked by the surrounding plate 1042, effectively preventing the condensate from entering the electronic control part, protecting the electronic control part, and increasing the service life of the electronic atomizer.
[0033] Further, please refer to Figure 3 , a liquid absorption cotton 1046 is disposed in the air intake space 1043. The liquid absorption cotton 1046 abuts against the inner wall of the surrounding plate 1042. The condensate generated during inhalation can be directly absorbed by the liquid absorption cotton 1046.

The air adjustment plate 1001 is provided with a through hole 1002 corresponding to the air inlet 1048. The air adjustment plate 1001 is further fixed with a sliding key 107. The sliding key 107 can drive the air adjustment plate 1001 to slide in the chute 105; the sliding key 107 is exposed through the air adjustment hole 1000; by adjusting the position of the air adjustment plate 1001 through the sliding key 107, the relative position of the through hole 1002 and the air inlet 1048 is changed, and thus the size of the connection between the air inlet 1048 and the outside is adjusted to adjust the air intake, improving the user experience.
[0039] Further, the size of the through hole 1002 is not less than the size of the air inlet 1048; this setting is to ensure that the rated maximum air intake does not decrease.
[0040] Specifically, in the aerosol generating device 1 provided by the first embodiment of the present utility model, the through hole 1002 and the air inlet 1048 have the same size.
[0041] Further, please refer to Figures 2 to 4 , an oil bottle 1003 is further provided in the housing 100. The oil bottle 1003 is arranged on the side of the main body part 1040 away from the atomization component 103; a mounting plate 1005 is fixed to the side of the bottom plate 1041. The mounting plate 1005 and the intake passage 1047 are arranged on opposite sides of the oil bottle 1003; it can limit the oil bottle 1003 to prevent it from shaking in the housing 100, reducing the risk of oil leakage and improving the structural stability.

The oil storage cotton 1030 wraps the atomization core 1031 and supplies oil to the atomization core 1031; an oil injection nozzle 1004 is provided on the oil bottle 1003 for supplying oil to the oil storage cotton 1030.
[0043] Further, a first circuit board 106 is provided on the side of the mounting plate 1005 away from the oil bottle 1003. The first circuit board 106 is electrically connected to a microphone 1007 at the position corresponding to the air hole 1045.
