Heat-not-burn aerosol-generating device

The utility model provides a heat-not-burn aerosol generating device. The heat-not-burn aerosol generating device comprises a shell assembly, a heating assembly, an airflow generating device and a flow guide part. A mounting cavity is formed in the shell assembly, the heating assembly is used for heating the aerosol generating substrate to generate aerosol, at least part of the airflow generating device is arranged in the mounting cavity, the airflow generating device comprises a port communicated with the mounting cavity, and the position of the port can generate positive pressure or negative pressure; the flow guide part is connected and communicated with a port of the airflow generation device, and when negative pressure is generated at the position of the port, the flow guide part can guide gas at the position of the electronic element to the port; when positive pressure is generated at the position of the port, the flow guide part can guide gas at the port to the position of the electronic component.
