Thin film heating sheet

The utility model relates to a novel thin-film heating sheet, which relates to a heating sheet using the series combination of ceramic heating bodies, which is used to solve the problems of easy overheating and burning, high failure rate, potential safety hazards and the like in the prior art; The upper and lower films are clamped with a metal heating sheet. The upper and lower films are made of materials with high temperature resistance and insulation characteristics, and the metal heating sheet is formed by winding, especially at the position of the two pole sheet of the metal potential sheet or at any selected position of the winding section of the metal heating sheet, a ceramic magnetic heating body (PTC) is combined in series to make use of the thermal resistance characteristics of the ceramic magnetic heating body, When the film heating element reaches the set high temperature, the ceramic magnetic heat generator presents a state of high resistance and low current conduction, so the effect of constant heat temperature can be obtained; The utility model is mainly used in the field of electric heating.
