Abstract
A cigarette device includes a housing, and a loading cavity, an airflow sensor, a circuit control unit, and a power supply are disposed in the housing. A fluid channel is located between the loading cavity and the housing, and the fluid channel is in communication with the outside of the housing and the inside of the loading cavity. An electromagnetic induction heating element surrounds the outside of the loading cavity; and the electromagnetic induction heating element is electrically connected to the power supply, and the circuit control unit is electrically connected to the airflow sensor and the electromagnetic induction heating element. When the cigarette device is used in combination with a cigarette added with a magnetic material, the cigarette can be heated uniformly and generate vapor quickly, to ensure a consistent vaping taste and improve utilization of tobacco while achieving immediate vaping and immediate stopping, which helps improve user experience.
