[0026] See also Figure 1-5 The utility model provides a technical solution: a cell freezing storage device. It includes a storage box 110, in which a storage component for freezing and storing cell test tubes is installed, and a refrigeration component for cooling the storage component is installed in the storage box 110;

[0027] The storage assembly includes a cooling box 210, which is installed in the storage box 110. The cooling box 210 is provided with a cavity. A plurality of partitions 240 are installed inside the cooling box 210. The plurality of partitions 240 are arranged at equal distances. The plurality of partitions 240 divide the inner cavity of the cooling box 210 into a plurality of cooling chambers 250. The plurality of cooling chambers 250 have a plurality of limiting grooves 251 on the bottom inner wall. The plurality of limiting grooves 251 are in an arc-shaped structure. The plurality of cooling chambers 250 have a plurality of first through holes 211 on the top. The plurality of first through holes 211 and the limiting grooves 251 are arranged at equal distances. A temperature sensor 260 is installed on one inner wall of the plurality of cooling chambers 250. The temperature in the cooling chamber 250 is monitored in real time by the temperature sensor 260, so that different cells can be stored at a suitable temperature. The partition 240 is made of heat-insulating material to reduce the impact of temperature differences between different cooling chambers 250 .

[0028] When storing different cells, different cells are isolated by placing different cell test tubes in different cooling chambers 250 respectively, and the test tubes are limited by the first through hole 211, the second through hole 231 and the limiting groove 251, and then the sealing cover 220 is clamped in the clamping groove 212, and then the cooling chamber 250 is refrigerated by the cooling mechanism 310 through the connecting pipe 320, the connecting pipe 330 and the transmission pipe 340, and different cells are frozen and stored. At the same time, the temperature sensor 260 in the cooling chamber 250 detects the temperature in the cooling chamber 250 in real time. When the temperature of the cooling chamber 250 reaches the set value, the transmission pipe 340 corresponding to the cooling chamber 250 is closed under the action of the solenoid valve 350, thereby achieving the storage effect of different cells, so that the storage box 110 can store different cells at the same time, thereby improving the flexibility of the storage box 110.

[0029] Limiting plates 230 are installed in the plurality of cooling chambers 250, and a plurality of second through holes 231 are provided on the plurality of limiting plates 230. The plurality of second through holes 231 are arranged at equal intervals, and the first through holes 211, the second through holes 231 and the limiting grooves 251 are located on the same vertical line. The limiting plates 230 are used to limit the cell test tubes so that the cell test tubes can remain stable during storage.

The cooling chamber 250 is sealed by the sealing cover 220, so that after the cells are taken out, the temperature in the cooling chamber 250 is not easy to change, and the leakage of cold air in the cooling chamber 250 is reduced.

[0031] A box cover 120 is installed on the top of the storage box 110, first lock buckles 111 are installed on both sides of the outer wall of the storage box 110, and second lock buckles 121 used in conjunction with the first lock buckle 111 are installed on both sides of the outer wall of the box cover 120. A mounting groove 130 for storing the cooling box 210 is provided on the top of the storage box 110, and a refrigeration cavity 140 for storing the refrigeration assembly is provided at the bottom of the storage box 110. The box cover 120 is installed on the storage box 110 by the first lock buckle 111 and the second lock buckle 121, and a sealing gasket is provided between the storage box 110 and the box cover 120, thereby reducing the leakage of cold air in the storage box 110.

[0032] The refrigeration assembly includes a cooling mechanism 310, which is mounted on the bottom inner wall of the refrigeration chamber 140. A connecting pipe 320 is mounted on the output end of the cooling mechanism 310. A connecting pipe 330 is mounted on the end of the connecting pipe 320 away from the cooling mechanism 310. The connecting pipe 330 is mounted on the bottom inner wall of the refrigeration chamber 140. Multiple groups of transmission pipes 340 are mounted on the side of the connecting pipe 330 away from the connecting pipe 320. The ends of the multiple groups of transmission pipes 340 away from the connecting pipe 330 respectively penetrate into the multiple groups of cooling chambers 250, and the multiple groups of transmission pipes 340 are all mounted with solenoid valves 350. The cooling chamber 250 is cooled by the cooling mechanism 310. The solenoid valve 350 is used to control the opening and closing of the transmission tube 340. When the temperature in the cooling chamber 250 reaches the set value, the solenoid valve 350 will be closed to keep the cooling chamber 250 at the set temperature. When the temperature of the cooling chamber 250 exceeds the set value, the solenoid valve 350 will be opened to cool the cooling chamber 250. By setting up multiple groups of transmission tubes 340 and solenoid valves 350, multiple groups of cooling chambers 250 can be maintained at different temperatures, so that the storage box 110 can store different cells.
