Among them, the semiconductor module 3 is a Peltier thermoelectric semiconductor refrigeration device in the prior art, which can efficiently refrigerate and maintain a low-temperature environment in the inner liner 1b, and the energy consumption is reduced by more than 85% compared with the compressor refrigeration.

[0031] In this embodiment, three shelves 4 are movably arranged along the direction from the box body 1 to the door 2. The length direction of the shelf 4 is the same as the direction from the box body 1 to the door 2, and the width direction of the shelf 4 is perpendicular to its length direction. Three plate grooves 5 are also provided on the door 2, and the three plate grooves 5 correspond to the three shelves 4 one by one and their extension direction is the same as the width direction of the shelf 4. Each shelf 4 is movably arranged in the corresponding plate groove 5 along its own length direction.

[0032] In this way, combined Figure 2 As shown, when it is necessary to take or place the culture or observe the cultivation status of the culture, the operator only needs to pull out the corresponding shelf 4 from the corresponding plate slot 5. After pulling it out, the culture on the shelf 4 can be taken or placed or observed, and there is no need to frequently open and close the box door 2, which effectively ensures the ambient temperature in the box body 1 and improves the cultivation quality of the culture; when it is necessary to continue the cultivation process, it is only necessary to reset the three shelves 4; and when it is necessary to open and close the box door 2, it is only necessary to continue to push the three shelves 4 from the reset position toward the box body 1, so that the shelves 4 are completely separated from the box door 2 and are located in the box body 1. At this time, the shelf 4 will not interfere with the box door 2, and the box door 2 can be opened and closed conveniently.

[0033] In this embodiment, combined with Figure 1-2 As shown, the shelf 4 includes a plate body 4a for placing cultures, and a sealing portion 4b arranged at one end of the plate body 4a close to the box door 2, the sealing portion 4b matches the internal contour of the plate slot 5, and the shelf 4 has a first position, a second position and a third position during its movement. When the shelf 4 is in the first position, the sealing portion 4b is engaged with the plate slot 5, and the plate body 4a is accommodated in the box body 1; when the shelf 4 is in the second position, the sealing portion 4b is separated from the plate slot 5 and relatively away from the box body 1, at this time, the plate body 4a is partially located in the box body 1 and partially located outside the box body 1; when the shelf 4 is in the third position, the sealing portion 4b is separated from the plate slot 5 and accommodated in the box body 1.

Locking grooves 7a are respectively arranged on the conical surfaces on both sides of the clamping portion 7b. The two locking blocks 8 can be inserted into the locking grooves 7a or separated from the locking grooves 7a during their movement. When the clamping portion 7b is accommodated in the clamping groove 4b1, the locking blocks 8 are inserted into the locking grooves 7a and realize relative locking between the clamping portion 7b and the clamping groove 4b1, which can prevent the sealing portion 4b from moving by mistake and affecting the sealing effect of the box body 1.
