[0022] It should be noted, however, that the design of traditional biochemical incubators mainly focuses on providing a constant temperature and humidity environment for biological samples, which is the basic condition necessary for the growth and reproduction of biological samples such as cells and microorganisms; but at the same time, these incubators often ignore a key issue, that is, microbial contamination; in the process of biological experiments, microbial contamination is an unavoidable and often occurring problem. Once the biological samples in the incubator are contaminated, these microorganisms may interfere with the normal progress of the experiment, resulting in inaccurate experimental results, or even complete failure. This not only wastes the experimenter's time and energy, but may also affect the progress of the entire scientific research project; therefore, in order to solve this problem, it is particularly important to develop a low-temperature biochemical incubator with sterilization function; this new type of biochemical incubator can not only provide a constant temperature and humidity environment, but also sterilize the inside of the incubator when necessary, effectively killing potential sources of microbial contamination, thereby ensuring the purity of biological samples during the culture process;

[0023] In this embodiment, the box body 1 is the main structure of the entire incubator, and the interior is divided into an installation room and a low-temperature room. The installation room is used to place auxiliary equipment such as a refrigerator 8 and an ozone generator 6, while the low-temperature room is used to place a rotating placement plate 3 and a culture dish 4 to provide a low-temperature culture environment for biological samples; the design of the box body 1 is reasonable, which not only ensures the stable operation of the internal equipment, but also provides a good low-temperature culture environment, which is conducive to the growth and reproduction of biological samples; driven by the driving mechanism, the rotating placement plate 3 can rotate in the low-temperature room, thereby driving the culture dish 4 to rotate; this design enables the biological samples in the culture dish 4 to be evenly exposed to the effects of cold liquid and ozone, thereby improving the culture effect and sterilization efficiency; the use of the rotating placement plate 3 not only facilitates the placement and removal of the culture dish 4, but also improves the utilization rate of the space in the incubator, and also helps to improve the culture effect of the biological samples; the setting of the opening and closing door 2 enables the experimenter to easily put in or take out the culture dish 4, and at the same time ensures the airtightness of the low-temperature room when closed.

[0025] In this embodiment, the driving mechanism is mainly composed of a rotating shaft 10, a motor 11 and a coupling 12. The rotating shaft 10 is rotatably mounted on the top of the low-temperature chamber and is fixedly connected to a plurality of placement trays 3 to ensure that the placement trays 3 can rotate with the rotating shaft 10. The motor 11 is fixed to the top of the box body 1 and is responsible for providing power; the coupling 12 connects the output shaft of the motor 11 and the top of the rotating shaft 10 to achieve power transmission; when the motor 11 is started, the power is transmitted to the rotating shaft 10 through the coupling 12, so that the rotating shaft 10 rotates in the low-temperature chamber. Since the rotating shaft 10 is fixedly connected to the placement tray 3, the placement tray 3 will also rotate with the rotating shaft 10. This design allows the culture dishes 4 on the placement tray 3 to rotate. The biological samples in the culture dish 4 can be evenly exposed to the effects of cold liquid and ozone, ensuring that the biological samples are fully cultured and sterilized; driven by the motor 11, the placement tray 3 can rotate automatically without manual operation, which greatly improves the automation level and work efficiency of the experiment; the rotation of the placement tray 3 enables the biological samples in the culture dish 4 to be evenly exposed to the effects of cold liquid and ozone, improves the culture effect and sterilization efficiency, and helps to obtain more accurate and reliable experimental results; the driving mechanism is compactly designed, occupies a small space, and can stably drive the placement tray 3 to rotate, ensuring the overall stability and reliability of the incubator.

The experimenter can open and close the box door 2 by operating the handle or related mechanism on the box door 2. The hinge 13 ensures that the opening and closing of the box door 2 is smooth and stable. Through the observation window 14, the experimenter can check the status of the culture dish 4 and the culture sample in the incubator at any time without opening the box door 2 frequently, thereby reducing the external microorganisms. In order to reduce the risk of intrusion, when it is necessary to ensure the sealing of the incubator, the experimenter can use the knob lock 15 to lock the door 2. When it is necessary to open the door 2, it is only necessary to rotate the knob lock 15 to unlock it. The design of the door 2 enables the experimenter to easily open and close the incubator and perform operations such as placing and removing the culture dishes 4; the setting of the observation window 14 enables the experimenter to observe the conditions in the incubator in real time, which helps to discover and solve problems in time; the use of the knob lock 15 ensures the sealing of the incubator during the culture or sterilization process, prevents the invasion of external microorganisms, and ensures the purity of the culture environment; by locking the door 2, unauthorized personnel can be prevented from opening the incubator at will, thereby improving the safety of the experiment.

At the same time, a number of heat dissipation ports are provided on the protective shell 16 to discharge the heat generated when the motor is running. When the motor 11 is running, a certain amount of heat will be generated inside. The existence of the protective shell 16 can effectively prevent external dust, debris or other adverse factors from directly contacting and damaging the motor, and protect its normal operation. At the same time, the design of the heat dissipation port enables the heat generated by the motor to be discharged in time, avoiding overheating of the motor and affecting its performance or life; the protective shell 16 can effectively prevent direct damage to the motor by external factors, and improve the service life and stability of the motor; the design of the heat dissipation port enables the heat generated by the motor to be discharged in time, ensuring the normal operating temperature of the motor and avoiding the occurrence of overheating problems; through the protective design of the motor, the risk of safety accidents caused by motor damage or overheating is reduced, and the safety of the entire incubator is improved.

[0030] In a further preferred embodiment of the utility model, a plurality of limiting seats 17 are fixedly mounted on the placing plate 3 , and grooves are formed on the limiting seats 17 , and the grooves are adapted to the culture dishes 4 .

[0031] In this embodiment, a plurality of limiting seats 17 are fixedly installed on the placing tray 3, and grooves are formed on the limiting seats 17, and the shapes and sizes of the grooves are adapted to the culture dishes 4; when placing the culture dishes 4, the experimenter only needs to place the culture dishes 4 in the grooves of the limiting seats 17.
