An atomizer is provided. The atomizer includes a liquid storage cup, a vibration device, and a lid body. The liquid storage cup is used to storage liquid. The vibration device is disposed through the liquid storage cup. The vibration device can vibrate in high frequency. The distance between a top of the vibration device and a bottom of the liquid storage cup is less than 3 mm. When the liquid level is below the top of the vibration device, the liquid in the liquid storage cup can be transported through the side wall to the top of the vibration device by liquid adhesion force. The lid body includes a mesh. When the lid body combines with the liquid storage cup, the mesh touches the top of the vibration device.一種霧化機,其包括一儲液槽、一震動裝置與一蓋體。儲液槽可用以儲存液體。震動裝置穿設於儲液槽,用以產生高頻震動。震動裝置的頂部距離儲液槽的底部小於3mm。當該儲液槽的液面低於該震動裝置頂部時,該儲液槽內的液體沿著該震動裝置的側壁,藉由附著力被輸送至該震動裝置的頂部。蓋體包括一噴孔片。蓋體與儲液槽相結合,噴孔片會與震動裝置的頂部相抵。10‧‧‧霧化器20‧‧‧儲液槽30‧‧‧震動裝置40‧‧‧蓋體50‧‧‧噴孔片X2‧‧‧距離
