[0027] The heating wire can be made of copper or other metal or alloy material with good electric heating characteristics. It can be understood that the cross-sectional diameter of the conventional heating wire is about 0.3 mm, and the heating wire is prone to be broken during transportation or heating operation. Therefore, the cross-sectional diameter of the heating wire is expanded to 0.4-0.6 mm in the design, the heating wire is thickened, the strength is improved, the heating wire is not prone to be broken, and the heating wire has good stability during high-temperature operation. However, the resistance of the heating wire is reduced, and according to the heating principle, the heating power P=U 2 / R.
