Abstract

The utility model provides an atomizer and an aerosol generating device. When a user sucks aerosol through the air outlet, under the action of negative pressure formed by suction, the air pressure difference is formed at two sides of the pneumatic trigger assembly, and the atomization core can be triggered to start atomization after the pneumatic trigger assembly senses the air pressure difference.

In addition, the pneumatic trigger assembly is arranged at a position close to the air outlet, so that the pneumatic trigger assembly is prevented from being corroded by atomized liquid or condensate leaked from the bottom of the atomizer, and is prevented from being failed or damaged, and the service life of the pneumatic trigger assembly is prolonged.

Because the porous structure of the porous flow-limiting piece 6 has a certain liquid locking capability, the atomized liquid can be bound and stored in the porous flow-limiting piece 6, and the capillary structure of the porous flow-limiting piece 6 can slowly and uniformly transfer the adsorbed and/or stored atomized liquid to the atomizing core in the atomizing cavity 14 through the liquid guide holes, so that the liquid supply rate of the liquid storage cavity 15 to the atomizing core in the atomizing cavity 14 is limited and slowed down, and the atomized liquid in the liquid storage cavity 15 is effectively prevented from directly flowing into the atomizing cavity 14 through the liquid guide holes, thereby effectively reducing the liquid leakage risk.

It will be appreciated that in some embodiments, the porous flow restrictor is at least one of porous cotton, porous sponge, porous fiberglass, porous ceramic, and porous graphite.
