Fresh food heat preservation box

Abstract

The invention provides a fresh food heat preservation box. The fresh food heat preservation box comprises a shell, a heat preservation box body and a storage drawer. A sealing cover is arranged on thefront side of the shell, and rollers are arranged at the bottom of the shell. The heat preservation box body is composed of extrusion type polystyrene and a vacuum insulation plate, wherein the vacuum insulation plate is arranged on the inner side of the extrusion type polystyrene. A refrigerant filling opening which is detachable is formed in the bottom end of the heat preservation box body. Thestorage drawer is made of plastic, and the inside of the storage drawer is coated with an activated carbon adsorption layer. The fresh food heat preservation box has the beneficial effects that the box body is thin in the thickness, light in the weight, good in the heat preservation effect, good in the shock resistance and buffering performances, antibacterial and bacteriostatic and convenient tomove, disassemble and wash.

Description

technical field [0001] The invention relates to an incubator, in particular to a fresh incubator. Background technique [0002] When biological vaccines, blood products, diagnostic reagents, vegetables and fruits, or other low-temperature preservation items are used, they need to be transported from the cold storage where they are stored to the desired destination. Changes in properties will cause these substances to become invalid. Therefore, in order to maintain their freshness, a device that maintains low temperature is required to store these substances during transportation. At present, cold chain incubators are generally used to store the above items. [0003] The cold chain incubator in the prior art is usually a simple combination of an incubator and an ice box, and its heat preservation effect is not ideal. In the actual use process, the heat preservation box is also affected by the ambient temperature. The cold air in the box leaks out continuously, the temperatu...

AI Technical Summary

Problems solved by technology

Vacuum insulation board and foam board are used to form the box body, which has light weight, low thermal bridge effect, good heat preservation effect, and good shock resistance and cushioning performance. However, its structure is simple, and the convenience of moving the box body is not considered, and there is no refrigerant filling cavity. It is inconvenient to store the refrigerant. In addition, the antibacterial performance of the box is not considered, and the hygienic effect of the storage space is poor.

Chinese patent CN201720927891.4 provides a vehicle-mounted mobile cold chain insulation box, which is composed of a box door and a box body. The box door is sealed and matched with the groove on the box body through a rubber strip. The inside of the box body and the box door is hollow by rotational molding. The cavity is filled with an insulating layer made of polyester foaming technology. The inner surface of the cavity is provided with a number of convex ribs to form a rib structure. The vehicle-mounted mobile cold chain incubator provided has a scientific and simple design, compact structure, more convenient maintenance, and high practicability, but its box body is made of foam material, and its insulation effect is poor compared with the vacuum insulation board under the same thickness. The box is designed without wheels, which is inconvenient to move. The antibacterial property is not considered in the box, and it is easy to breed microorganisms during the storage of items

[0006] To sum up, there is no cold chain incubator that meets the requirements of light weight, low thermal bridge effect, good shock resistance and cushioning performance, convenient movement, easy cleaning, antibacterial and antibacterial properties, and good heat preservation effect.
