During operation, when stay cord 6 rebound, be located stay cord 6 and go up fixture block 61 and begin rebound in step, fixture block 61 contacts refrigerant bag 42 and reactant bag 41 respectively at rebound's in-process, and then lead to the fracture of refrigerator bag and reactant bag 41, make refrigerant and reactant mix in refrigerating chamber 4 and take place the reaction, further refrigerant bag 42 and reactant bag 41 that has avoided in certain refrigerating chamber 4 do not break and react, thereby lead to the appearance of refrigeration effect reduction and the inhomogeneous phenomenon of refrigeration.
The specific working process is as follows:
when the portable refrigeration food packaging bag works, because the space between the inner layer bag 1 and the outer layer bag 2 is uniformly divided into a plurality of refrigeration chambers 4 during the manufacturing process, a plurality of refrigerant bags 42 and reactant bags 41 are respectively placed in the corresponding refrigeration chambers 4 during the manufacturing process, and the refrigeration food packaging bag is sealed, only the bag opening is used for placing food materials, for example, when the high-value food materials needing to be refrigerated and stored, such as fresh seafood, are transported for a short distance of dozens of minutes to several hours at high temperature after the seafood is purchased in a supermarket or when the high-value food materials are taken home or given as gifts to other persons, the high-value food materials are placed into the disposable portable refrigeration food packaging bag, the bag opening is sealed, the high-value food materials in the bag are ensured to be in a low-temperature refrigeration state, so that the freshness of the food materials is ensured, and simultaneously, before the high-value food materials are placed into the packaging bag, the portable refrigeration food packaging bag is extruded, at the moment, the reactant bag 41 and the refrigerant bag 42 in the refrigeration chamber 4 are simultaneously extruded by external pressure, the reactant bag 41 and the refrigerant bag 42 are broken, water in the reactant bag 41 and refrigerant in the refrigerant bag 42 simultaneously flow into the refrigeration chamber 4 and react in the refrigeration chamber 4, meanwhile, as the reactant is water and the refrigerant comprises the components of sodium bicarbonate, biuret and dimethyldiurea, the refrigerant is dissolved in the water in the refrigeration chamber 4 to perform endothermic reaction, further absorbs the surrounding heat and generates refrigeration effect, the outer layer bag 2 is made of metal film material, the air cavity 21 is formed in the outer layer bag 2, the existence of the air cavity 21 enables the outer surface of the outer layer bag 2 to generate micro-stripe bulges, and the air cavity 21 is filled with foamed polyurethane material, the foamed polyurethane material is filled in the air cavity 21, then micro stripe bulges are formed on the outer surface of the outer layer bag 2, the plastic heat pipes 5 are installed in the cavity 3, the refrigerating chamber 4 is formed by separating the plastic heat pipes 5, the plastic heat pipes 5 are annularly wrapped on the outer wall of the inner layer bag 1, the plastic heat pipes 5 are uniformly distributed along the vertical direction, cross grids are oppositely formed between the plastic heat pipes 5 and the air cavity 21, the pull rope 6 is pulled upwards, as the pull rope 6 passes through the pull rope hole and penetrates through the refrigerant bag 42 and the reactant bag 41, when the pull rope 6 moves upwards, the refrigerant bag 42 and the reactant bag 41 penetrated by the pull rope 6 move upwards along with the pull rope 6, and then contact the upper surface of the refrigerating chamber 4 to cause the refrigerant bag 42 and the reactant bag 41 to be crushed by the upper surface of the refrigerating chamber 4, so that the refrigerant bag 42 and the reactant bag 41 which are not crushed after the packaging bags are partially crushed are crushed, make refrigerant and reactant take place the reaction in refrigeration chamber 4, stay cord hole is passed to stay cord 6, when stay cord 6 upwards draws, because the effect of rubber block 51 self elasticity, stay cord hole inner wall hugs closely on stay cord 6 all the time, thereby guarantee to be in encapsulated situation in refrigeration chamber 4 all the time, when stay cord 6 rebound, be located stay cord 6 and go up fixture block 61 and begin rebound in step, fixture block 61 contacts refrigerant bag 42 and reactant bag 41 respectively at rebound in-process, and then lead to the fracture of refrigerator bag and reactant bag 41, make refrigerant and reactant mix in refrigeration chamber 4 and take place the reaction.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
