Film cannot be capped, once capped, if limiting temperature function without PTC, capped Electric radiant Heating Film is possible to temperature and constantly rises
It is high and generate security risk；Self limiting temperature PTC Electric radiant Heating Film, its working principle is that, Electric radiant Heating Film reaches under set temperature state, if warm
Degree increases, and resistance just will increase, so that electric current reduces, temperature undying would not be increased, so that temperature is controlled in safety
In reasonable range.The formation of PTC function is mainly since the conductive carbon film of PTC Electric radiant Heating Film is by conductive nano ion and high score
Sub- material is made through special formulation and precision process；In the state of being not powered on, conductive nano ion is equal with smaller spacing
Even is distributed in high molecular material body, and after energization, as electric energy is efficiently converted into thermal energy, high score handset material is gradually swollen
The swollen spacing for having pulled open conductive nano ion, so that bulk resistance is gradually increased, heating function is gradually reduced, to realize from limit
The function of mild energy-saving and frequency-variable, sufficiently meets human body to the comfort requirement of soft heating；But at present if high in conductive carbon film
Molecular material dosage is excessive, causes conductive nano ion concentration lower, can reduce the electric conductivity of conductive carbon film in this way, influences to lead
The fever of electrical carbon film；If high molecular material dosage is moderate or less, the expansion of high score handset material and the degree reduced are inadequate, shadow
Self limiting temperature regulating effect is rung, current PTC self limiting temperature Electric radiant Heating Film there is this problem；For this purpose, Chinese Patent Application No.:
201720989979.9, a kind of self limiting temperature PTC Electric radiant Heating Film is disclosed, is successively lower-layer insulating film, expansion glue, fever from bottom to up
Layer and upper insulating film, the heating layer include positive and negative anodes metal current-carrying item, are communicated between the positive and negative anodes metal current-carrying item
Conductive carbon film, the conductive carbon film are tightly attached to the expansion glue surface and form integral structure, and the conductive carbon film is macromolecule
Material fills conductive nano ion；After the utility model Electric radiant Heating Film is powered, the expansion amplitude of expansion glue expanded by heating is much larger than institute
The expansion amplitude of high molecular material is stated, therefore expansion glue can be further driven to high molecular material expansion, make in high molecular material
The spacing of conductive nano ion is further opened, and conductive carbon film resistance increases, and fever reduces, and electrical carbon film temperature will not continue to
It rises, compared to existing self limiting temperature Electric radiant Heating Film, the self limiting temperature regulatory function of the utility model Electric radiant Heating Film is more preferable；But on front side of Electric radiant Heating Film
If there is covering, it is easy to cause Electric radiant Heating Film hot-spot, above-mentioned PTC electric heating film reaction is slow, is easy electric heating membrane damage.
Summary of the invention

Heat, each area realize independent temperature, and being capable of the other zone currents of joint debugging.
The self limiting temperature PTC Electric radiant Heating Film of the utility model, pet waterproof insulation bottom, and it is set to pet waterproof insulation bottom top
The electromagnetic shielding protective layer in face can guarantee that electric heating layer work is more stable；And it is set to electromagnetic shielding protective layer top surface
Expansion glue-line, expansion glue-line uses subregion domain structure, and heat only quickly transmitting from region, and heat can not divide it
Its region is enable to respond quickly the expansion glue-line of high hot-zone；Make the conductive nano ion in the high molecular material in the region
Spacing is further opened, and conductive carbon film resistance increases, and is set to the electric heating layer of expansion glue-line top surface；And it is set to electric heating
The pet waterproof insulation top layer of layer top surface；Expanded glue-line top surface offers interlaced slot electrode；The electric heating layer includes
