The specific embodiment

Understand and enforcement the utility model for the ease of those of ordinary skills, the utility model is described in further detail below in conjunction with the drawings and the specific embodiments.

Embodiment 1, see Fig. 1, make a portable freezing device with the technical solution of the utility model, comprise a casing 1, insulation cover 2, heat-insulation layer 3 and frozen coating 4, wherein, the internal diameter of casing 1 is 7 centimetres, and height is 18 centimetres; The thickness of heat-insulation layer 3 is 7 millimeters, frozen coating 4 is nested in the inside of heat-insulation layer 3, and it is high together with heat-insulation layer 3, the thickness of frozen coating is 1.3 centimetres, be filled with cold-producing medium in the frozen coating 4, described cold-producing medium is mixed by ice and salt, and frozen coating 4 inside are refrigerating chambers 5, is provided with movable demarcation strip 6 in the described frozen coating, described demarcation strip 6 is easy slashings of annular independently, be nested in the inside of frozen coating 4, frozen coating 4 is separated up and down, the internal diameter size of demarcation strip 6 is slightly larger than the external diameter size of refrigerating chamber 5, the external diameter size of demarcation strip 6 is slightly less than the internal diameter size of frozen coating 4, the number of demarcation strip 6 is 2, is spaced from each other the ice sheet and the salt deposit of cold-producing medium, is ice sheet from the bottom up, salt deposit, ice sheet, salt deposit, described ice sheet and salt deposit thickness proportion are 2.5:1, wherein, salt is 50 grams, and ice is 125 grams, ice is graininess with salt, the thickness of demarcation strip 6 is 0.8 millimeter, makes demarcation strip 6 fragmentations by the vibrations household freezer during use, ice is contacted with salt and begin and mix; In this example, the temperature of refrigerating plant can reach-10 ℃, and remains in-10 ℃ ~ 0 ℃ temperature range and reach 7 hours.

The thickness difference of demarcation strip, shock strength are also different, shake household freezer under certain dynamics, make that demarcation strip can be not broken simultaneously, the dynamics of vibrations is strong more, and broken is many more, refrigerating speed is fast more, therefore can be according to the speed of actual conditions control refrigeration and the time of consecutive low temperature.

Embodiment 2, see Fig. 2, the internal diameter of casing 1 is 7 centimetres, and height is 18 centimetres; The thickness of heat-insulation layer 3 is 7 millimeters; The thickness of frozen coating is 1.3 centimetres, the thickness proportion of described ice and salt deposit is 2.53 ︰ 1, ice sheet and salt deposit respectively are 3 layers, alternately deposit, it promptly successively is ice sheet, salt deposit, ice sheet, salt deposit, ice sheet, salt deposit, demarcation strip thickness difference between every layer, be respectively 1 millimeter from the bottom up, 0.8 millimeter, 0.6 millimeter, 0.8 millimeter, 1 millimeter, other same embodiment 1, present embodiment adopts the different demarcation strip of shock strength, can apply certain dynamics according to actual needs and shake the portable freezing device, make and the time fragmentation that does not coexist different of the shock strength that demarcation strip bears according to self mix the control refrigeration thereby reach cryosel.

This example is used when shaking the portable freezing device when being equivalent to 2.5 kilograms impulsive force, and 0.6 millimeter demarcation strip breaks fast, and the ice sheet and the salt deposit that are separated begin hybrid refrigeration, and minimum temperature can reach-5 ℃, and maintains below 0 ℃ 3 hours; Continue vibrations portable freezing device, this moment, 0.8 millimeter demarcation strip broke, and other ice sheet and salt deposit begin hybrid refrigeration, and minimum temperature can reach than before and descend 2 ℃, and the time that maintains below 0 ℃ increases by 3 hours; Continue vibrations portable freezing device, this moment, 1 millimeter demarcation strip broke, and last ice sheet and salt deposit begin hybrid refrigeration, only need 3 minutes can reach-7 ℃ before and after this example, and remained in-7 ℃ ~ 0 ℃ temperature range and reach 8 hours, good constant-temperature effect.

In order further to improve this product refrigeration, described demarcation strip 6 can also adopt different thickness, according to actual needs, select different dynamics vibrations household freezers, thereby cause the quantity of demarcation strip different time fragmentation different with broken area, refrigeration is also different, and the time of consecutive low temperature is also different.

This refrigeration case has refrigeration and heat insulation effect preferably, when ice with after salt joins frozen coating 4, temperature reduces rapidly in the refrigerating chamber 5, the minimum temperature that can reach is relevant with the mixed proportion of ice and salt, ice is graininess with salt, the branch multilayer is spaced from each other and places in the frozen coating, between whenever two-layer demarcation strip 6 is arranged, the thickness difference of demarcation strip 6, the shock strength difference makes demarcation strip 6 fragmentations by the vibrations household freezer during use, makes the contact of cryosel layer begin to mix, general a few minutes just can reach minimum temperature, and refrigerating speed is all fast more a lot of than common refrigerator.After refrigerating chamber 5 temperature reduced, the duration of low temperature was also relevant with the heat insulation effect of heat-insulation layer 3, and this layer can adopt vacuum layer, and then the retention time of the cryogenic effect of lengthening.

In process of refrigerastion, ice and salt melt gradually, form salting liquid at last, and temperature also can slowly raise, once arrive temperature after, pourable original salting liquid adds new ice sheet and salt deposit and can continue to freeze.Salting liquid originally can recycling, and such as drying the back water evaporates, salt wherein can crystallize out, and can utilize again again, thereby environment is not produced any pollution.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.
