Technical Field

The utility model relates to an electron cigarette technical field to specifically relate to an electron smog spinning disk atomiser and electron cigarette including this electron smog spinning disk atomiser.

Background

The electronic cigarette is a novel article different from a traditional cigarette, and can generate smoke by atomizing tobacco tar through an atomizer. As one of the core components of the electronic cigarette, the most common atomizer in the prior art utilizes oil-guiding materials such as tobacco cotton, non-woven fabric, and fiber rope, and then heats the materials by resistance wires. For example, the utility model with the publication number of CN205040656U discloses a non-contact electric heating wire electronic cigarette atomizing core, which comprises an atomizing core shell, a wiring electrode, an electric heating wire and a liquid guiding cotton, wherein the electric heating wire is spirally wound, the electric heating wire is spirally arranged in the atomizing core shell, and the liquid guiding cotton is arranged in or outside the electric heating wire spiral; wherein an isolation tube is arranged between the electric heating wire and the liquid guide cotton, and the wall of the isolation tube is provided with a vent hole; the liquid guide cotton can be arranged on the inner side of the spiral electric heating wire, the spiral electric heating wire is transversely arranged in the atomizing core shell, the isolation pipe is arranged between the inner side of the electric heating wire and the liquid guide cotton, the electric heating wire is in close contact with the outer wall of the isolation pipe, and the liquid guide cotton is in close contact with the inner wall of the isolation pipe.
