[0001] The utility model relates to the technical field of cell culture, in particular to a carbon dioxide incubator for cell culture. Background Art

[0002] CO2 incubators for cell culture are widely used in biomedical research, drug development, vaccine production, cell therapy, and other fields. By providing stable growth conditions, researchers can better study cell characteristics, drug responses, and their performance in different environments.

[0003] After searching, Chinese patent announcement number: CN220846071U discloses a carbon dioxide incubator for cell culture, which relates to the field of cell culture technology; the utility model includes an incubator body and a support frame, the inner wall of the incubator body is provided with an adjustment component, the adjustment component is connected to the support frame, the support frame and the inner surface of the incubator body are slidably fitted, and a storage plate is detachably provided inside the support frame, and a fixing component is provided inside the storage plate. When the internal space of the incubator body needs to be adjusted, the utility model can drive the connecting rod to rotate by turning the dial wheel, so that the screw can be rotated, so that the sleeve block mounted on its outer surface moves downward, and the sleeve block moves downward. The support frame can also move downward through the support groove and the support slider, thereby adjusting the space between the support frames and adapting to culture dishes of different sizes. The ratchet can be stuck by the first spring and the ratchet after the adjustment is completed to prevent the dial wheel from rotating due to accidental touch or vibration.

[0004] However, in actual use, when the user needs to take out or put in a certain layer of culture, the entire box must be opened. Every time the box is opened, the temperature, humidity and carbon dioxide concentration are greatly disturbed. Each door opening operation will cause instantaneous fluctuations in environmental conditions, affecting the stable growth of cultures in other layers, so that the internal temperature and humidity need to reach the set standards again. At this time, the incubator needs to consume more energy to restore to the optimal working state, which will affect the stable growth of cultures in other layers.

[0005] Therefore, the utility model provides a carbon dioxide incubator for cell culture. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a carbon dioxide incubator for cell culture, comprising a culture box body 1, a layered assembly 2 fixedly connected to the interior of the culture box body 1, and an air supply assembly 3 fixedly connected to the exterior of the culture box body 1;

[0031] The layered assembly 2 includes an air transfer plate 21, the outer side of which is fixedly connected to the incubation box 1. An air supply cavity 22 is provided inside the air transfer plate 21. Air supply fans 23 are fixedly connected to both sides of the top of the air transfer plate 21. A cultivation cabinet 24 is slidably connected to the interior of the incubation box 1. An air inlet 25 is provided at the bottom end of the incubation cabinet 24. The incubation box 1 serves as the overall external frame, and the layered assembly 2 fixedly connected inside can effectively separate different culture layers, ensuring that when a layer is opened, the culture environment of other layers is not affected. The air transfer plate 21 in the layered assembly 2 is fixed to the inner side of the incubation box 1. The air supply cavity 22 is provided inside the air transfer plate 21, which can achieve uniform distribution of carbon dioxide gas. Air supply fans 23 are fixedly connected to both sides of the top of the air transfer plate 21. When the incubator is working, the air supply fans 23 will start and evenly deliver carbon dioxide gas to each layer through the air supply cavity 22 to ensure that the gas concentration of each layer remains consistent. The interior of the incubation box 1 is slidably connected to the incubation cabinet 24. This design not only makes it convenient for users to take out or put in cultures from the box, but also ensures that each layer can be operated independently, reducing interference with other culture layers. Each incubation cabinet 24 is provided with an air inlet 25 at the bottom end. These air inlet holes 25 can effectively guide the gas into the interior of the incubation cabinet 24, ensuring that the gas environment in the incubation cabinet always remains stable and uniform, providing a constant and ideal growth environment for cell culture.

[0032] Furthermore, if Figure 1 - Figure 3As shown: the air supply assembly 3 includes an air intake block 32, the top of the air transfer plate 21 is inclined from the air intake block 32 to the air supply fan 23, one end of the air transfer plate 21 is fixedly connected to the air intake block 32, the outer side of the air intake block 32 is fixedly connected to the cultivation box 1, the outer side of the air intake block 32 is fixedly connected to the air supply pipe 31, the bottom end of the cultivation cabinet 24 is slidably connected to the air supply pipe 31, and the outer side of the cultivation box 1 is installed with an air outlet valve 33, the air outlet valve 33 is distributed in an array on the cultivation box 1 and is parallel to the cultivation cabinet 24. The air intake block 32 in the air supply assembly 3 is a key component of the gas entry system, responsible for guiding the gas to flow into the air transfer plate 2 1. The top of the air transfer plate 21 is inclined from the air inlet block 32 toward the air supply fan 23. This inclined design helps the gas flow smoothly to the air supply fan 23, reduces the resistance to gas flow, and improves the gas delivery efficiency. The air inlet block 32 is fixed to one end of the air transfer plate 21, and its outer side is also fixedly connected to the incubation box 1, ensuring the stability of the overall structure and forming a sealed air supply channel to prevent gas leakage. The air outlet valves 33 are distributed in an array on the outside of the box and are arranged parallel to the incubation cabinet 24. The function of the air outlet valves 33 is to discharge excess gas inside the box while maintaining the pressure and flow balance of the internal gas.

[0033] Working principle:

[0034] like Figure 1 - Figure 4 As shown:

[0035] During use: first, carbon dioxide gas enters the air intake block 32 in the air supply assembly 3 through the air supply pipe 31, and the air intake block 32 guides the gas to the air transfer plate 21, and then the internal air supply cavity 22 of the air transfer plate 21 evenly distributes the gas. At the same time, the inclined design of the top of the air transfer plate 21 allows the gas to flow smoothly to the air supply fan 23. After the air supply fan 23 is started, it will further push the carbon dioxide gas through the air supply cavity 22 and evenly enter each layer of the incubation cabinet 24. At the same time, the air inlet 25 at the bottom of the incubation cabinet 24 guides the gas into the interior of the incubation cabinet 24, ensuring that each incubation layer can maintain a stable and uniform gas environment. The incubation cabinet 24 is slidably connected to the air supply pipe 31 to ensure that the continuity of the gas is not affected during operation. Finally, the air outlet valve 33 array is responsible for discharging excess gas inside the box, maintaining the gas pressure and flow balance in the system, thereby ensuring that the gas concentration and environmental conditions in each layer of the incubation cabinet 24 are always stable, achieving the effect of providing an ideal growth environment for cells.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
