For solving its technical problem, technical solution adopted in the utility model is:
The described electric food warmer cold and hot flexible deposited end, electric food warmer comprises the bottom of a pan, heating tube is provided with outside the bottom of a pan, the corresponding the bottom of a pan arranges the egative film that shape with it adapts, egative film adopts Heat Conduction Material, egative film is arranged cold and hot telescopic chute, the bottom of a pan, egative film and heating tube weld together in turn, the setting alternate with heating tube of cold and hot telescopic chute.
The utility model process is as follows:
The first step, the electric food warmer applying the end as required chooses the egative film of corresponding size shape;
Second step, the cold and hot telescopic chute of punch process on egative film;
3rd step, is undertaken adding thermal weld by the bottom of a pan, egative film and heating tube.
Above-mentioned processing step is simple to operate, and production efficiency is high, and wherein, second step and the 3rd step can be exchanged.
During use, heating tube heating power, egative film realizes the heat trnasfer between heating tube and the bottom of a pan, after the bottom of a pan and egative film expanded by heating, because coefficient of thermal expansion and contraction is different, egative film deformation quantity is different with pot bottom-shape variable, the power of expanding with heat and contract with cold is split by the cold and hot telescopic chute of egative film, deformation quantity is shared on multiple cold and hot telescopic chute, reduces the interaction force between egative film and the bottom of a pan, thus reaches the object not ftractureing and do not snap.
Wherein, preferred version is:
Described egative film adopts individual layer or double-deck aluminium flake, and aluminium flake heat conductivility is good, the preferred aluminium soldering of welding process.
Cold and hot telescopic chute on described egative film is set to groove; Cold and hot telescopic chute comprises straight shape groove and deep-slotted chip breaker, straight shape groove and deep-slotted chip breaker are symmetrical arranged about plate center, straight shape groove is extended to its edge by plate center, between adjacent two straight shape grooves, some deep-slotted chip breakers are set, tie point is remained with between each straight shape groove and deep-slotted chip breaker, keep the integrative-structure of egative film, heat-conducting effect is even.
Cold and hot telescopic chute on described egative film is set to groove; Described cold and hot telescopic chute comprises cannelure and straight shape groove, and straight shape groove and deep-slotted chip breaker are symmetrical arranged about plate center, and straight shape groove runs through cannelure, and cold and hot telescopic chute is set to not open type, even if arrange the problem that cannelure also need not worry egative film slitting.
Described heating tube cross section is trapezoidal, semicircle or circular.
Compared with prior art, the utility model has following beneficial effect:
The utility model can effectively prevent the deposited end from ftractureing, and simplifies production technology, reduces production cost, enhances productivity.Heating tube heating power, egative film realizes the heat trnasfer between heating tube and the bottom of a pan, after the bottom of a pan and egative film expanded by heating, because coefficient of thermal expansion and contraction is different, egative film deformation quantity is different with pot bottom-shape variable, and the power of expanding with heat and contract with cold is split by the cold and hot telescopic chute of egative film, and deformation quantity is shared on multiple cold and hot telescopic chute, reduce the interaction force between egative film and the bottom of a pan, thus reach the object not ftractureing and do not snap.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
Embodiment 1:
As Figure 1-3, the electric food warmer described in the utility model cold and hot flexible deposited end, electric food warmer comprises the bottom of a pan 1, heating tube 2 is provided with outside the bottom of a pan 1, the corresponding the bottom of a pan 1 arranges the egative film 3 that shape with it adapts, and egative film 3 adopts Heat Conduction Material, egative film 3 is arranged cold and hot telescopic chute 4, the bottom of a pan 1, egative film 3 and heating tube 2 weld together in turn, the setting alternate with heating tube 2 of cold and hot telescopic chute 4.
