Negative pressure dry ice food storage box

Abstract

The invention discloses a negative pressure dry ice food storage box which comprises a box body, a box cover, a piston exhaust pump and a dry ice storage chamber, wherein an upper end opening of the box body is provided with sealing sockets; a lower end opening of the box cover is provided with corresponding sealing insertion edges; the box body is internally provided with a food storage chamber; the food storage chamber is internally provided with the dry ice storage chamber, and is divide into a plurality of food storage cells; and the piston exhaust pump is mounted in the box body through an air pump mounting port formed in the side surface of the box body. The negative pressure dry ice food storage box has the function of pumping air, and the interior of the sealed food storage chamber is forced to be in a negative pressure state through pumping a part of air in the box body; in addition, the dry ice storage chamber has the functions of storing dry ices and releasing carbon dioxide gas; the food storage chamber is filled with the released carbon dioxide gas, bacteria are difficult to survive and reproduce due to the fact that bacteria are kept in a negative pressure environment and in the carbon dioxide gas for a long time, so that the function of inhibiting bacteria is exerted; bacteria breeding in the food storage chamber is avoided or reduced; spoilage of food is retarded; negative pressure dry ice food storage box is high in efficiency and low in cost; and the purpose of storing the food well is achieved.

Description

technical field [0001] The invention belongs to the field of food storage devices, in particular to a negative pressure dry ice food storage box. Background technique [0002] Currently, food is usually stored in food storage boxes, food storage cabinets, and food storage bins. However, when food is stored in an environment of normal temperature and pressure, bacteria will continue to grow and deteriorate, which will pollute the indoor environment for a long time and affect human health. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a negative pressure dry ice food storage box with simple structure, easy manufacture and easy operation, so as to avoid or reduce the breeding of bacteria in food storage and delay deterioration. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: negative pressure dry ice food storage box, including box body, box...
