[0002] Cell culture refers to a method of simulating the in vivo environment in vitro to enable cells to survive, grow, reproduce and maintain their main structures and functions. Cell culture is also called cell cloning technology, and the formal term in biology is cell culture technology. Cells can be transformed from a single cell into a simple single cell or a multi-cell with minimal differentiation through mass culture, which is an indispensable part of cloning technology. The cell culture incubator is a common cell culture device. Researchers place the sampled cell into the cell culture incubator and adjust the environmental parameters in the cell culture incubator to culture the cells.

[0027] like Figure 2 As shown, the base 1 is a hollow shell, and a circulation mechanism for circulating hot air in the incubator 3 is arranged in the base 1, and a temperature sensor 28 is installed on the inner wall of the incubator 3. The temperature sensor 28 and the circulation mechanism are connected to the controller through wires respectively. The temperature sensor 28 monitors the temperature inside the incubator 3 and timely feeds back the temperature situation in the incubator 3 to the controller so that the controller can control the circulation mechanism;
[0028] Among them, Figure 2 As shown, the circulation mechanism includes a circulation fan 23 arranged in the base 1, and the circulation fan 23 is connected to the controller through a wire. An air outlet duct 24 and an air suction duct 27 are installed on the circulation fan 23, and the other end of the air suction duct 27 is arranged on the bottom of the incubator 3. The air outlet duct 24 passes through the base 1 and is arranged in the inner wall of the incubator 3, and the end of the air outlet duct 24 away from the circulation fan 23 is connected to an air outlet hood 26, and the air outlet hood 26 is arranged on the top of the incubator 3, and a heating wire 25 is installed in the air outlet hood 26, and the heating wire 25 is connected to the controller through a wire. The air in the incubator 3 will flow from top to bottom under the action of the circulation fan 23, and then the circulation fan 23 will send the air extracted from the incubator 3 to the air outlet hood 26 and heat it by the heating wire 25, and then enter the incubator 3, so as to realize the hot air circulation operation.
[0029] like Figure 1 As shown, a plurality of shelves 5 arranged at intervals are provided in the incubator 3, both sides of the shelves 5 are mounted on drawer rails 6, and the drawer rails 6 are fixed to the inner wall of the incubator 3, so that the shelves 5 can be moved to the outside of the incubator 3 by pulling, and a plurality of vents 7 are provided on the shelves 5, so that the hot air in the incubator 3 can freely pass through the shelves 5 and flow to the suction duct 27;

The sliding setting of the slider 16 in the slide groove 15 will limit the rotation of the screw rod 12, so that when the hand-tightening nut 14 is rotated, it can drive the screw rod 12 to move linearly in the support tube 11, so as to push the stopper 13 out of the through hole 10;
[0031] The utility model also includes a culture dish 21 for placing culture medium and cell tissues. The culture dish 21 corresponds to the placement groove 8, so that after the culture dish 21 is placed in the placement groove 8, a gap can be formed between the placement groove 8. A top cover is provided on the top of the culture dish 21, and an annular arc groove 22 is opened along the bottom edge of the culture dish 21, and the arc groove 22 corresponds to the stop block 13.

At this time, the screw 12 will push the first stop block 13 to approach the culture dish 21 and stop on the arc groove 22 of the culture dish 21. Among them, the stop block 13 is a non-slip elastic rubber block, which increases the stress strength of the stop block 13 on the culture dish 21. At this time, the culture dish 21 will be fastened in the placement groove 8 without shaking or sliding. Then, the shelf 5 is pushed back into the incubator 3, and the sealing door 4 is closed to start cell culture.
[0033] Furthermore, in order to prevent the screw rod 12 from slipping off the hand nut 14 when the hand nut 14 is tightened, a limit plate 17 is installed on the end of the screw rod 12 away from the stop block 13 to limit the movement of the screw rod 12 in the support tube 11.
