Heating assembly and atomizing core

The utility model discloses a heating assembly and an atomizing core, the heating assembly comprises at least three heating pins and at least two heating bodies, the at least three heating pins are arranged in parallel and at intervals, and the at least two heating bodies are respectively arranged between two adjacent heating pins. The heating assembly is high in heating efficiency, so that the evaporation speed of the aerosol matrix is higher, the reduction degree of the aerosol formed by evaporation is higher, the resistance values of the at least two heating bodies are different, the heating efficiency of the at least two heating bodies is different, different heating requirements of users can be met, and the heating efficiency of the aerosol matrix is improved. In addition, the layering sense of aerosol can be stronger, the smoking experience of a user is better, meanwhile, circulation of the internal temperature of the atomization core provided with the heating assembly can be accelerated, heat conductio
