An aerosol generating device including a housing of which is provided therein with a cavity for receiving a smokable material; a holding mechanism for holding the smokable material in the cavity along the radial direction and an infrared emitter located outside the cavity along the radial direction to radiate infrared rays to heat the smokable material. A distance between an inner surface of the infrared emitter and the central axis of the cavity is larger than the shortest distance between the holding mechanism and the central axis of the cavity, so that a certain space is maintained between the smokable material and the inner surface of the infrared emitter when the smokable material is received in the cavity, thereby preventing the infrared emitter from heating the smokable material by contact conduction.

An aerosol-generating system includes an electric heater, a battery and control circuitry. The electric heater is configured to vaporize an aerosol-forming substance. The battery is configured to power the electric heater. The control circuitry is configured to: prevent charging of the battery in response to detecting that the electric heater is in an operation state; or prevent operation of the electric heater in response to detecting that the battery is in a charging state.
