The heating bodies of common low-temperature smoking sets with internal heating mainly include ceramic needles with sintered heating lines, ceramic sheet heating bodies, and heating bodies with metal shells wrapping heating coils (hereinafter referred to as "coil heating bodies"). Among them, the ceramic needle heating body has a slow heating speed due to its large mass and high self-heat absorption; the ceramic needle and ceramic sheet heating bodies are prone to brittle fracture due to the inherent brittleness of ceramic; the ceramic sheet heating body is also prone to bending and breaking due to its thinness; and the coil heating body has poor product consistency due to the deformation of the heating coil.
