As shown in fig. 3, since the aerosol generating device is small in size, when a user uses the aerosol generating device, the external air entering the atomizer 100 through the air inlet 123 can be quickly sucked into the air inlet, and the air guide pillar 122 is arranged so that the external air enters the air inlet channel 126 through the air inlet 123, then directly flows through the smoke gathering area 34 under the guiding action of the air guide pillar 122, and carries the smoke at 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 matching effect of the air inlet channel 126 and the smoke gathering area 34 prevent outside air entering the atomizer 100 through the air inlet hole 123 from directly flowing to a non-smoke gathering area in the atomizer 100, and then the outside air is not mixed with smoke in the smoke gathering area 34 under the sucking effect of a user, namely the outside air is sucked into a suction port of the user, so that the smoke in the suction port is not uniformly mixed, the taste is too light, and the experience is not good.
The utility model provides an atomizer 100, relative fixed cover 121 towards the slip notes liquid pipe 21 of direction near liquid storage chamber 111, liquid feeding hole 215 communicates with liquid storage chamber 111, can inject liquid into liquid storage chamber 111 through liquid feeding hole 215, and exhaust hole 127 sets up along the axial of fixed cover 121, sealing member 24 can seal exhaust hole 127 directly or relieve the seal to exhaust hole 127, simple structure, simple to operate; meanwhile, the fixing sleeve 121 is formed by partially sinking the end cover 12, so that the situation that the fixing sleeve 121 is separately arranged in the liquid injection structure 20 and the installation structure between the fixing sleeve 121 and the liquid storage component 10 is not firm, so that the liquid injection structure 20 is easy to loosen and is not tight in sealing is avoided; meanwhile, one part is omitted in the liquid injection structure 20, so that the installation is simple and the cost is saved.
The utility model provides an aerosol generating device, because it has the whole technical characteristics of above-mentioned atomizer 100, the event has the same technological effect with above-mentioned atomizer 100.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
