The connection between the atomizing head 30 and the liquid storage assembly 10 is also realized.

As shown in FIG. 3 , due to the small size of the aerosol generating device, when the user uses the aerosol generating device, the outside air entering the atomizer 100 through the air inlet 123 will be quickly sucked by the user into the mouth, and the air guide column 122 will It is set so that the outside air enters the air intake channel 126 through the air intake hole 123 and flows directly through the smoke gathering area 34 under the guidance of the air guide column 122, and carries the smoke in the smoke gathering area 34 to be sucked by the user through the smoke outlet 112. ; The guiding effect of the air guide column 122 and the cooperation between the air inlet passage 126 and the smoke accumulation area 34 prevent the outside air entering the atomizer 100 through the air inlet hole 123 from directly passing to the non-smog accumulation area in the atomizer 100 , and then it is sucked into the user's mouth before being mixed with the smoke in the smoke gathering area 34 after the user's inhalation, resulting in uneven mixing of the smoke in the user's mouth, the taste is too light, and the experience is not good.

In the atomizer 100 provided by the present invention, the liquid injection pipe 21 is slid relative to the fixed sleeve 121 in the direction close to the liquid storage cavity 111 . liquid is injected inside, and the exhaust hole 127 is arranged along the axial direction of the fixed sleeve 121, the sealing member 24 can directly seal the exhaust hole 127 or release the sealing of the exhaust hole 127, the structure is simple, and the installation is convenient; The cover 12 is partially recessed to avoid a separate fixing sleeve 121 in the liquid injection structure 20, and the installation structure between the fixed sleeve 121 and the liquid storage assembly 10 is not firm, resulting in the liquid injection structure 20 being easily loosened and the sealing is not tight; at the same time, the liquid injection structure 20 One component is reduced, the installation is simple, and the cost is saved.

Since the aerosol generating device provided by the present invention has all the technical features of the above-mentioned atomizer 100 , it has the same technical effect as the above-mentioned atomizer 100 .

Taking the above ideal embodiments according to the present invention as inspiration, through the above description, the relevant staff can make various changes and modifications without departing from the scope of the present invention. The technical scope of the present utility model is not limited to the content in the description, and its technical scope must be determined according to the scope of the claims.
