Electronic cigarette

Abstract

An electronic cigarette with an atomizing core having multiple atomizing assemblies arranged in parallel is provided. An atomizing seat of the atomizing core is provided with multiple accommodating grooves for accommodating the electric heating wires, and the electric heating wires are spaced from each other with a space interval, which solves a problem that the smoke generated by the electric heating wire cannot be delivered by the airflow in time when the liquid guiding rope is positioned between the electric heating wires and the amount of the smoke is reduced. Each of the electric heating assemblies may be mounted directly from the open end of the respective accommodating grooves, which simplifies the installation and the production process.
