Description

Heat generation assembly and aerosol forming device The present invention relates to the field of technology for heated non-combustion smoking devices, and in particular to a heating assembly and an aerosol forming device. Electronic cigarettes are a substitute for tobacco and are gaining increasing interest and popularity due to their benefits, such as safety, convenience, health, and environmental protection; for example, there are heated non-combustion electronic cigarettes, also known as heated non-combustion aerosol forming devices. Conventional heating non-combustion aerosol forming devices generally utilize tubular peripheral heating or center insertion heating; tubular peripheral heating involves a heating tube surrounding the outer surface of an aerosol forming substrate (e.g., tobacco) to heat the substrate, while center insertion heating involves inserting a heating assembly into the substrate to heat it. Here, heating assemblies are widely applied due to features such as simple manufacturing and ease of use. Current heating assemblies are primarily formed by using a ceramic or insulated metal base, printing or coating a resistance heating circuit onto the base, and then fixing the resistance heating circuit to the base through high-temperature treatment. However, since the resistance heating circuit on the conventional heating assembly is a single thin film that is later printed or coated on a ceramic base, when the heating assembly is inserted into an aerosol-forming substrate multiple times, the resistance heating circuit is prone to detaching from the base and lacks stability when subjected to high-temperature heating due to the curved shape of the base. Furthermore, during the heating process, the resistance heating circuit only contacts the aerosol-forming substrate on one side of the base where the resistance heating circuit is installed and does not contact the aerosol-forming substrate on the rear side of the base, resulting in poor heating uniformity for the aerosol-forming substrate.
