The invention discloses an air supplementing device and an
aerosol generating device. The invention relates to the field of
aerosol generating devices. The invention particularly discloses the air supplementing device. A communicating port and a communicating pipeline are arranged; the communicating port is adjacent to a
smoke outlet; when the air supplementing device is used , a cigarette can bedirectly smoked after being in direct contact with the
smoke outlet; at the moment, the communicating pipeline generates air
pressure difference at a
microphone under the suction action of a user, themicrophone drives a host to supply power to a
smoke cartridge so as to start the smoke
cartridge, the user can directly drive the smoke
cartridge to work through simple smoking steps, the smoke cartridge is driven to work only when the user smokes, and the starting operation of the user is simplified. Meanwhile, a covering plate is arranged to abut against the end, close to the communicating port, of a boss; when a user smokes
aerosol, aerosol or
mixed gas remaining at the suction
nozzle can be prevented from entering the
microphone through the communication pipeline at the moment of stoppingsmoking, tobacco
tar stain residues, caused by long-term use of the user, of the communication pipeline can be effectively avoided, and gas can also be prevented from flowing back into a smoke cartridge or a main
machine.
