▎ 摘　　要

NOVELTY - The induction device comprises a first conductive structure (1211) and a second conductive structure (1212), which are arranged on a side wall (12a). The first conductive structure and the second conductive structure allow the side wall to flow along an axial flow of the side wall. A jacking piece (123) is located at an inner side of the side wall. A first end of the jacking piece is convex and points to the second conductive structure. A first end of the jacking piece is connected with the second conductive structure to contact with the first conductive structure. The material of the first conductive structure has metal or graphene. An isolation material (122) is located between the first conductive structure and the second conductive structure. USE - Induction device for use in an electronic cigarette (claimed). ADVANTAGE - The induction device determines whether the user is sucking by judging whether the first conductive structure and the second conductive structure of the induction device are connected. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an electronic cigarette comprising a first airway and the induction device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural diagram of an induction device.
