Refrigerating device capable of being used outdoors for long time

Abstract

The invention relates to refrigerating device capable of being used outdoors for a long time. The refrigerating device capable of being used outdoors for a long time comprises a refrigerating barrel for holding food materials, wherein an upper cover and a lower cover are arranged at the upper end and the lower end of the refrigerating barrel in a covering way; buckles are fixedly arranged on the outer side wall of the refrigerating barrel; and the lower cover and the upper cover are fixedly connected with the refrigerating barrel through the buckles. The refrigerating barrel with the two communicating upper end and lower end is arranged, a half-opened cover plate is arranged on the upper cover, and a suddenly opened gap is smaller relatively, so that the refrigerating barrel cannot carry out heat exchange with the outside easily; meanwhile, a heat-insulation shielding membrane is arranged in the refrigerating barrel, a first membrane body and a second membrane body bend downwards underpressure when the food materials are placed in the refrigerating barrel, the food materials are leaked on the lower cover, and the heat-insulation shielding membrane is rebounded and goes back to theinitial state so as to seal a lower space, so that the occurrence of the phenomenon that a cold source in the lower space is diffused outwards can be reduced, the heat loss is reduced, a refrigerating effect is kept, and the dosage of liquid nitrogen is reduced.

Description

technical field [0001] The invention relates to the technical field of food refrigeration, in particular to a refrigeration device that can be used in the field for a long time. Background technique [0002] At present, most of them use ice cubes or refrigerators for refrigeration. Ice cubes are not only heavy as a cooling source, but also cannot be kept refrigerated, while refrigerators need electricity. Although there is a portable power supply for battery life, it still cannot be used in the wild for a long time. use. Contents of the invention [0003] In order to overcome the problems raised by the technical background, the present invention provides a refrigeration device that can be used in the field for a long time. [0004] The technical solution of the present invention is specifically as follows: a refrigeration device that can be used in the field for a long time, including a refrigerator bucket for containing food materials, the upper and lower ends of the ref...
