Abstract: An electronic cigarette and an atomizer are disclosed, the atomizer includes a reservoir, the reservoir being configured for storing tobacco liquid; an atomizing assembly, the atomizing assembly being disposed inside the reservoir, at a lower end of the reservoir, and configured to absorb tobacco liquid for atomization; and a blocking component, the blocking component being disposed in the reservoir, and configured for blocking tobacco liquid in the reservoir when tobacco liquid flows from the lower end of the reservoir toward an upper end thereof, such that tobacco liquid is kept around the atomizing assembly, and hence avoiding few tobacco liquid existing in the atomizing assembly because of rapid flowing of the tobacco liquid such that the electronic cigarette may generate burnt flavor when smoked.

Abstract: A cartridge comprises an outer sleeve tube, an air passage tube located in the outer sleeve tube, and an atomization device. An annular space between the outer sleeve tube and the air passage tube forms a liquid storage chamber configured for storing tobacco liquid. The liquid storage chamber has an annular opening, which is blocked with a porous liquid conducting body. The porous liquid conducting body has a first surface and an opposite second surface, and is configured for conveying the tobacco liquid from the first surface to the second surface and supplying the tobacco liquid to the atomization device, the first surface being in contact with the tobacco liquid in the liquid storage chamber and the second surface being in contact with the atomization device. The atomization device is configured for aerosolizing the tobacco liquid to generate an aerosol to be expelled into the air passage tube.

Abstract: An exemplary mouthpiece assembly includes a mouthpiece. The mouthpiece includes a sucking end, a connecting end, and an air passage. The sucking end defines an air outlet, and the connecting end defines an air inlet. The mouthpiece assembly further includes a partition element dividing the air passage into an air intake chamber and an air outlet chamber. The mouthpiece further includes a sidewall defining at least one first through hole and at least one second through hole, the first through hole is in communication with the air intake chamber, and the second through hole is in communication with the air outlet chamber. The mouthpiece assembly further includes an air adjusting ring defining at least one gap. The air adjusting ring is rotatable relative to mouthpiece, so that an overlapped area among the first through hole, the at least one gap, and the second through hole can be changed.

Abstract: An electronic cigarette includes an atomizing device and a power pole, the atomizing device includes a first connecting assembly, and the power pole includes a second connecting assembly. The first connecting assembly includes a pair of first electrodes and at least one lapping portion. The second connecting assembly includes a pair of second electrodes and a cavity with at least one adapting portion formed therein and a guiding surface formed adjacent to the at least one adapting portion. The at least one lapping portion is capable of inserting into the cavity from the guiding surface and rotatable in the cavity until abuts the at least one adapting portion, whereby the first electrodes are in contact with and thus electrically connected to the respective second electrodes. An atomizing device, a power pole and a charger connector are also provided.

Abstract: In alternative embodiments, the invention provides products of manufacture, such as arrays or microarrays, comprising cells and compounds such as small molecules or drugs for e.g., drug screening or toxicity testing.
