Aerosol generating device and indicating lamp assembly thereof

The utility model relates to the technical field of aerosol generating devices, in particular to an indicator light assembly of an aerosol generating device. A light guide piece in the indicator lamp assembly is provided with a light guide base body and a light guide protrusion, the light guide base body covers an indicator lamp hole, the light guide protrusion is located on the side, facing an indicator lamp, of the light guide base body, and a light receiving face is located on the light guide protrusion, so that light emitted by the indicator lamp can enter the light guide base body through the light guide protrusion and then penetrate through the light guide piece to enter the indicator lamp hole. And ejecting the shell. In the early design stage of the sol generation device, the brightness of the indicator lamp hole can be adjusted by changing the light receiving quantity of the light receiving surface on the light guide bulge, and the efficiency of the design link can be improved. 本实用新型涉及气溶胶生成装置技术领域，具体涉
