US Patent 9687029 Electronic cigarette with multiple atomizer assemblies

An electronic cigarette with multiple atomizing assemblies is provided. The atomizing assembly includes a first atomizing device and a second atomizing device. When the cigarette liquid is atomized by the first atomizing device, the smoke generated by the first atomizing device generally contains large particles of the cigarette liquid that have been not sufficiently. The large particles of the cigarette liquid that have been not sufficiently atomized are delivered by the smoke towards the second atomizing device. When passing through the second atomizing device, the cigarette liquid that have been not sufficiently atomized is atomized again by the second atomizing device, thereby enabling the smoke to be more soft and smooth, subtly increasing the amount of the smoke, and preventing the user from sucking in large particles of the cigarette liquid that have been not sufficiently atomized.
