Abstract

An atomizing assembly has an inhaler, an atomizing assembly and an atomizing core. The atomizing assembly has a shell. The atomizing core joins with the shell. The shell has a gas flow passage and a liquid storage cavity which encircles the gas flow passage and serves for liquid storage. The atomizing core has a core body, an exhaust tube and an atomizing element. The core body is provided with an atomizing cavity, and the exhaust tube is disposed at a gas outlet. The atomizing element is disposed within the atomizing cavity and is used for liquid atomization; at least a part of the exhaust tube extends into the gas flow passage, and a through hole or a gap communicates with the interior of the exhaust tube. The gas flow passage is disposed on the sidewall of the exhaust tube.

Claims
