Abstract

The present invention relates to an aerosol generating device and belongs to the field of aerosol generation technology. The aerosol generating device comprises a housing assembly, a support assembly, a deformation member, an airflow sensing sensor, and a control circuit board. The support assembly is positioned inside the housing assembly, and a receiving chamber is formed inside the support assembly. The deformation member is positioned within the receiving chamber and partitions the receiving chamber to form a heating chamber and a sensing chamber. The heating chamber and the sensing chamber are positioned separately from each other. The sensing chamber has a sealed structure, and the airflow sensing sensor is installed inside the sensing chamber to detect pressure change information. The control circuit board is electrically connected to the airflow sensing sensor and is configured to output information on the number of inhalations by the user based on the detected pressure change information. When the user performs an inhalation action, the deformation member deforms, causing a change in air pressure within the sensing chamber, and the airflow sensing sensor and the control circuit board cooperate to calculate the number of inhalations by the user, thereby enhancing the user experience.
