Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is further described:
As shown in Figure 1, PTC constant temperature electric heating mat applying comprises heating desk mat main body 1, power switch line 2.Heating desk mat main body is by heat-insulation and heat-preservation heelpiece 1-1, and PTC constant temp. warming film 1-2, is incubated insulation epidermis 1-3 and is composited, and above insulation insulation epidermis, is fixed with power line Connection Block 1-4; Described heat-insulation and heat-preservation heelpiece, PTC constant temp. warming film, insulation insulation epidermis is made by flexible material, can bend with curling; Bonding with powerful heat conduction glue between described heat-insulation and heat-preservation heelpiece and PTC constant temp. warming film; Bonding with powerful heat conduction glue between described PTC constant temp. warming film and insulation insulation epidermis; Described heating desk mat body surfaces is fixed with power line Connection Block; Between described power line Connection Block and described intermediate layer PTC constant temp. warming film, by wire, connect, centre has waterproof insulation glue to fill; Between power line Connection Block and heating desk mat main body, pass through screw fastening.Described PTC constant temp. warming film is directly used civil power 220v or civil power 110v power supply; Described heating desk mat main body can be by the specification of change PTC constant temp. warming film, coupling civil power 220v or civil power 110v power supply; Power switch line comprises power supply lead wire, heating driving switch, overcurrent protection insurance, power supply indicator and attaching plug.Attaching plug can insert civil power 220v or civil power 110v power supply.
