Summary of the invention

[0004] The utility model aims to provide a quick-freezing container based on the pressure difference principle, which can make the generated cold air actively flow quickly inside the food, thereby accelerating the speed of cooling the food, improving the pre-cooling effect, and facilitating the cold chain transportation of the food.
