  • Publication number: 20180343924
    Abstract: An electronic cigarette includes a casing, a mouthpiece, a sensing unit, an atomizing member, a liquid storage member, a fluid transportation device and a power supply device. When the sensing unit senses an airflow, the sensing unit transmits an enabling signal to the power supply device and the power supply device accordingly controls the fluid transportation device to operate. The fluid transportation device guides the cigarette liquid out from the liquid storage member through an intake passage and transfers the cigarette liquid to a liquid conduit of the atomizing member through an outtake passage. The cigarette liquid transferred to the liquid conduit infiltrates out the through holes so as to be transferred to the electric heater of the atomizing member at a fixed amount. Consequently, an atomized vapor is generated and the user can inhale the atomized vapor through the opening of the mouthpiece.
