The utility model discloses an embodiment relates to a kind of atomization devices, in particular to a kind of sealing element, upper cover subassembly and fragrance
machine, sealing element is set to the upper cover of fragrance
machine, for when the upper cover cover is set on the main body of fragrance
machine, with the elastic sealing contact of the inner wall of the gas outlet of the gas outlet end of atomization subassembly;Wherein, sealing element is also provided with exhaust passage along the preset axis direction, and exhaust passage is respectively communicated with the gas outlet end of atomization subassembly and each gas passage of upper cover.The sealing element compared with prior art not only can realize the elastic sealing of the inner wall of the gas outlet of the gas outlet end of atomization subassembly, guarantee the sealing performance of the gas outlet end of atomization subassembly, but also through the exhaust passage set on sealing element, the blowing strength after
airflow passes through atomization subassembly can also be guaranteed, so that atomization medium can be smoothly carried out from each gas passage by
airflow, to reach good mist effect.
