US Patent 10201189 Atomization core device and electronic cigarette

An atomization core device has an electrode column, a liquid guiding element and a heating wire. The electrode column has a hollow liquid storage chamber. A peripheral wall of the electrode column is provided with a through-hole in communication with the liquid storage chamber. The liquid guiding element and the heating wire wrap around the outer periphery of the electrode column, and the liquid guiding element covers the through-hole. The atomization core can reduce the carbon deposition, increase the life of the heating wire, keep the original taste of the tobacco liquid, and reduce the occurrence of dry heating and leakage.
