The heat insulating layer 101 can be made of a heat insulating material. The heating layer 102 is provided with a heating circuit, which can generate heat when energized, and performs heating work. The hollow cavity formed by the protective layer 103 is used for inserting a flue-cured tobacco, and the hollow cavity is generally cylindrically shaped to fit the rod-shaped flue-cured tobacco.

It can be understood that the heating unit assembly 100 is used in a flue-cured tobacco device, and the flue-cured tobacco device is provided with a battery assembly and a control circuit. The positive and negative electrodes of the battery assembly can be electrically connected to the positive electrode and the negative electrode of the heating layer 102 through the positive electrode lead and the negative electrode lead, respectively.
