Abstract
The present disclosure discloses a mouthpiece of a nebulizer, comprising an aerosol inflow port, and an aerosol outflow port; wherein an aerosol passage is formed between the aerosol inflow port and the aerosol outflow port, such that in a normal spraying state, the aerosol enters the aerosol passage from the aerosol inflow port and is discharged from the aerosol outflow port; and at least one temporary liquid reservoir is provided inside the mouthpiece, such that when condensation of the aerosol reversely flows back towards the aerosol inflow port, at least part of the condensation of the aerosol flows back into the temporary liquid reservoir. Besides, the present disclosure further discloses a portable nebulizer adopting the mouthpiece. The present disclosure provides an advantage of causing the nebulizer to produce a better anti-backflow effect.
