Low-temperature storage box
By designing a sealing cover and a motor-controlled opening and closing mechanism on the detection port of the cryogenic storage box, the problem of difficulty in opening the door caused by the large pressure difference between the inside and outside is solved, achieving low-energy pressure balance and reducing cold leakage, thus improving the efficiency of use.

AI Technical Summary
Technical Problem
Existing cryogenic storage boxes are difficult to open due to the large pressure difference between the inside and outside at low temperatures. Existing electric heating balancing devices consume a lot of energy and reduce the insulation layer, increasing cold leakage.
Method used
The sealing device is designed using a detection hole, and the opening and closing of the sealing cover is controlled by a motor to balance the pressure inside and outside the box, reducing reliance on electric heating devices.
Benefits of technology
It reduces energy consumption, minimizes cold leakage, improves pressure balance efficiency, has a simple structure, and is easy to operate.

Abstract
This utility model discloses a cryogenic storage box, including a detection hole on the box body, a sealing device for controlling the opening and closing of the detection hole, a sealing cover covering the detection hole, and an opening and closing mechanism for controlling the movement of the sealing cover. This utility model utilizes the existing detection hole structure of the cryogenic storage box, replacing the original rubber plug of the detection hole with a sealing cover that has a certain heat insulation effect. The detection hole balances the pressure inside and outside the storage box, eliminating the need for a separate electric heating balancing device, thus reducing energy consumption and cold leakage. The opening action is detected and judged, and the activation of the transmission sealing device is controlled by a set control method, improving the pressure balancing efficiency and reducing cold leakage. The structure is simple, requiring only the addition of a sealing device next to the detection hole on the back.
