Connect；First generating component from the beginning of in the middle part of the insulation film detours according to arc-shaped profile and lines up ground floor, then
Outwards detour according to arc-shaped profile and line up the second layer, the second layer is located at the outside of ground floor, then per layer it is outside successively
Detour arrangement；The structure that detours of second generating component is identical with the first generating component, first generating component and second
The symmetrical separation of generating component is in the both sides of the insulation film.Using this technical scheme, first generating component and second
Generating component is symmetrical, and according to arc-shaped profile per layer arrange successively, the efficiency of heating surface is high, heats more uniform.
Used as further improvement of the utility model, the arc-shaped profile is semi-circular profile.
As further improvement of the utility model, it is described per layer between spacing be not less than 5mm.
Used as further improvement of the utility model, one end of the temperature protection switch is electrically connected with generating component, institute
State the other end of temperature protection switch to be connected with the negative or positive electrode of power supply.It is using this technical scheme, easy to connect, easily make
Make.
Compared with prior art, the beneficial effects of the utility model are：
First, using the technical solution of the utility model, the profile of heater arrangement is circle, with heated disc
Overall dimensions are consistent, and both are completely covered overlap, and the material of heating plate is not wasted, and has saved cost.
