[0002] A biological experiment refers to a process of studying and exploring organisms including cells, tissues, organs, individuals, etc. under a laboratory environment using various experimental techniques and methods. Among them, in order to culture cell and microorganism samples, a culture device for biological experiments is needed for use.

[0003] After retrieval, the Chinese utility model patent discloses a biological culture device for biological experiments with the publication number of CN220685081U. A top box is fixedly connected to the top of the culture chamber. A pressing mechanism is arranged inside the top box. A moving-out mechanism is arranged inside the culture chamber. A culture dish is arranged inside the moving-out mechanism. A sealing cover is inserted into the top of the culture dish. The pressing mechanism includes a downward pressing component. The downward pressing component is arranged inside the culture chamber. A pulling component is arranged on one side of the downward pressing component. In this biological culture device for biological experiments, through the arranged pressing mechanism, the spring in a compressed state will push the round plate downward, and then the round plate will push the pressing plate in the direction close to the top of the sealing cover through the round rod, so that the bottom of the pressing plate contacts the top of the sealing cover. Under the elastic action of the spring, the sealing stability of the sealing cover is further improved, so that the sealing cover will not easily fall off, achieving a good culture sealing environment, and being convenient for staff to operate and use, improving the operation efficiency of the device.

[0004] However, when the above device is in use, it lacks a stirring function. When in use, it is not easy to fully mix the cells and microorganisms inside the incubator with the culture solution and not easy to scrape off the cells and microorganisms attached to the inner wall of the incubator.
