Heating assembly and heating blanket

The utility model provides a heating assembly and a heating blanket, the heating assembly is used for being installed on the heating blanket, the heating assembly comprises a fixing layer and a heating layer, the heating layer is arranged on the fixing layer, the heating layer comprises a plurality of heating areas and hollow areas, and the hollow areas are arranged on the fixing layer. And one hollow area is arranged between any two adjacent heating areas. The heating layer of the heating assembly is designed to be hollowed out, so that a hollowed-out area is formed between every two heating areas, heat generated by the heating areas can be diffused to the hollowed-out areas, heat conduction is more uniform, and the situation that the temperature is too high due to the fact that heat in the center of the heating layer is too concentrated is avoided; therefore, the user is prevented from being scalded in the using process. Under the condition that the effective heating area of the heating layer is not changed
