Heating assembly and aerosol-generating device

Abstract

The application provides a heating assembly and an aerosol generating device. The heating assembly comprises a cup body and a heating body. The cup body is internally provided with a center portion and an outer portion arranged outside the center portion. The center portion has a receiving cavity and a heating cavity. One end of the receiving cavity has an opening. The heating body is arranged in the heating cavity. The heating body is used for heating airflow flowing into the heating cavity into hot airflow. The hot airflow is used for flowing into the receiving cavity to heat an aerosol product. The outer portion is provided with a first air inlet channel. The first air inlet channel has an air inlet end and an air outlet end. The air inlet end is arranged on a side close to the opening. The air outlet end is arranged on a side away from the opening. One end of the heating cavity is communicated with the air outlet end. The other end of the heating cavity is communicated with the receiving cavity. The heating assembly can integrate the first air inlet channel, the heating cavity for heating the hot airflow and the receiving cavity for accommodating the aerosol product in the cup body. The structure design in the device is simplified. The overall sealing performance of the cup body is good. The smoking experience of the user is improved.
