An electronic cigarette is disclosed and comprises a power device, a sensor, an atomizing portion, a liquid transmitting device, a liquid storage element, a shell and a nozzle. The liquid storage element is for accommodating a cigarette liquid the liquid transmitting device is for transmitting the cigarette liquid into the atomizing portion, so that the cigarette liquid could be controlled to be quantitatively transmitted to the atomizing portion to generate atomized smoke the sensor comprises an airflow sensor and an air pressure sensor, so as to change the speed of atomizing the cigarette liquid atomized by the atomizing portion and the fluid-supplying speed of the liquid transmitting device the shell comprises an air inlet on its outer surface, and the nozzle closes the end of the shell.一種電子香煙,包含:電源裝置;霧化部件;液體存儲部件,內部儲置香煙液體;流體輸送裝置,以控制輸送液體存儲部件之香煙液體滴落量至霧化部件上;傳感器,包含氣流傳感器及空氣壓力傳感器,以改變霧化部件煙油霧化的速度和流體輸送裝置之供液速度;殼體外表具有進氣口;吸嘴封閉殼體一端。1b‧‧‧第二殼體1e‧‧‧支撐座1f‧‧‧氣流通道4‧‧‧霧化部件41‧‧‧電加熱器42‧‧‧液體滲透部件5‧‧‧液體存儲部件51‧‧‧通道52‧‧‧儲液容器6‧‧‧流體輸送裝置6a‧‧‧輸入通道6b‧‧‧輸出通道7‧‧‧支架
