Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, 2, from heating transfusion packaging, comprise insulation packing container 1, insulation container wall is followed successively by heat-conducting layer 2, chip layer 3, sealing coat 4, packed layer 5 and heat insulation layer 6 from inside to outside.Fill in packed layer 5 and meet the mixture that exothermic reaction can occur air, mixture can be made up of iron powder, water, wood powder, active carbon, Sal and Vermiculitum.Sealing coat 4 is for isolating chemical substance and chip layer 2, and prevent chemical reaction defective chip layer 2, heat-conducting layer 2 has good heat conductivility, and the heat effectively discharged by chemical reaction conducts to the soft bag of internal layer (as transfusion flexible bag 13 or soft transfusion bottle) efficiently.
At least one chip line unit 7 is set in chip layer 3, the structure of chip line unit as shown in Figure 3,4, chip line unit 7 comprises battery 8(battery 8 and adopts button cell), PTC9 and electromagnetic induction coil 10, one pole of battery 8 is connected with one end of PTC9, the other end of PTC9 is connected with one end of electromagnetic induction coil 10, another pole of battery 8 is connected with the other end of electromagnetic induction coil 10, and electromagnetic induction coil 10 is vertical with sealing coat 4 to be arranged.
Heat insulation layer 6 arranges at least one air-vent 11, the external port wall of air-vent 11 is arranged the magnetic sheet 12 of this air-vent 11 salable, and a side of magnetic sheet 12 is connected on the external port wall of air-vent 11; Magnetic sheet 12 is corresponding with electromagnetic induction coil 10, and the magnetic sheet 12 that electromagnetic induction coil 10 is energized on the magnetic pole and heat insulation layer 6 that produce forms peer and repels each other.Except air-vent 11, other positions of heat insulation layer 6 all can prevent heat to external diffusion as much as possible.
When the quantity of the electromagnetic induction coil 10 in chip line unit 7 is multiple, multiple electromagnetic induction coil 10 can be connected successively, the other end of PTC9 connect with multiple electromagnetic induction coil 10 after one end be connected, another pole of battery 8 connect with multiple electromagnetic induction coil 10 after the other end be connected.Multiple electromagnetic induction coil 10 also can be in parallel, and the other end of PTC9 is connected with one end of multiple electromagnetic induction coil 10 respectively, and another pole of battery 8 is connected with the other end of multiple electromagnetic induction coil 10 respectively.
Chip line unit 7 is by button cell energy supply, the size of current of control circuit is carried out by PTC9, namely, temperature raises, resistance increases, and electric current reduces, the field weakening of electromagnetic induction coil 10 (magnetic sheet 12 that the magnetic pole of electromagnetic induction coil 10 and heat insulation layer 6 are arranged forms peer and repels each other), when the field weakening of electromagnetic induction coil 10 time, magnetic sheet 12 closes to air-vent 11; Otherwise when the temperature decreases, magnetic sheet 12 opens to the opposite direction of air-vent 11, open air-vent 11.Thus the control of temperature to air-vent 11 folding can be realized.
Chip line unit 7 is arranged between the soft bag of internal layer (as transfusion flexible bag 13 or soft transfusion bottle) and chemical substance, its PTC9 can be subject to the combined influence of chemical exothermal and the soft bag actual temperature of internal layer simultaneously, if the soft bag temperature of internal layer reduces on the one hand, the resistance value of PTC9 also can reduce, and starts air-vent 11; If chemical exothermal is too fast on the other hand, heat sharply raises, and the resistance value of PTC9 increases, and closes air-vent 11, slows down the speed of reaction, thus plays the control of differential conciliation to temperature control, avoids the delayed of temperature control effect.
What finally illustrate is, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although with reference to preferred embodiment to invention has been detailed description, those of ordinary skill in the art is to be understood that, can modify to technical scheme of the present invention or equivalent replacement, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of right of the present invention.
