Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0025] Specific implementation time: as Figures 1-4 The utility model discloses a pollution -preventing culture medium split device, which comprises a chassis 1 and a test tube 4 arranged above the chassis 1, one side of the chassis 1 is provided with a drive part 5;

[0026] Sterilization subassembly 6, sterilization subassembly 6 is arranged at the drive end of drive part 5;

[0027] Culture medium is an important basis for microbial culture and experiment, and its quality directly affects the accuracy and effectiveness of experimental results. In the laboratory, the preparation of culture medium usually needs to use a dispensing device, because of the accuracy, sterility and experimental repeatability requirements of the culture medium formula. If the culture medium is manually dispensed, it is not only easy to be disturbed by human factors, such as inaccurate dispensing amount or contamination during operation, but also introduces foreign microorganisms because the complete sterile state cannot be ensured during dispensing, thereby affecting the experimental results. In order to solve these problems, the dispensing device emerges as the times require.

[0028] As shown in Figure 1 , Figure 3 and Figure 4 , the sterilization assembly 6 includes a connecting plate 601 arranged at the driving end of the driving member 5 and an air pipe 608 above the connecting plate 601. The surface of the connecting plate 601 is designed as an opening, and the through hole of the connecting plate 601 is provided with an air pipe 602 and can blow hot air to the outer surface of the test tube 4. The air pipe 608 is at the same level as the air pipe 602, and the diameter of the air pipe 608 is consistent with the inner wall diameter of the test tube 4. A connecting shell 609 is arranged below the fixed shell 605, and the side opposite to the fixed shell 605 is designed as a plane. The air pipe 608 is located in the connecting shell 609, and the air outlet end of the air pipe 608 extends to the outside of the connecting shell 609. A first air pump 606 is fixedly connected to the inner upper side of the fixed shell 605. The air outlet end of the first air pump 606 is communicated with a double-tube pipe. The two ends of the double-tube pipe of the first air pump 606 are respectively communicated with an air bag 607 and the air pipe 608. The air bag 607 is located at the plane part between the fixed shell 605 and the connecting shell 609.

[0029] When the test tube 4 filled with culture medium rotates, the driving member 5 drives the connecting plate 601 to move downward. At this time, the air pipe 602 in the connecting plate 601 will be sleeved on the outer surface of the test tube 4, and the fixed shell 605 and the connecting shell 609 will enter the test tube 4. Then the driving member 5 drives the sterilization assembly 6 to move downward, and at this time the hot air device 8 is opened. The second air pump sends the hot flow in the hot air device 8 to the air pipe 602 and the air pipe 608 respectively. At this time, the air pipe 602 and the air pipe 608 can blow sterilization hot flow to the inner and outer surfaces of the test tube 4 at the same time, which can achieve the effect of sterilizing the test tube 4 in all directions.

[0030] When the drive member 5 is lowered to a certain position and returns, the pipeline valve in communication with the air bag 607 is opened, and the first air pump 606 will inject air into the air bag 607, so that the air bag 607 expands between the two flat parts of the fixed shell 605 and the outer shell 609 and extends outward, until the surface of the air bag 607 is in contact with the inner wall of the test tube 4. At this time, the air bag 607 rising with the drive member 5 can wipe the inner wall of the test tube 4, which can effectively reduce the microbial contamination on the hands or tools of the operator, thereby reducing the risk of cross contamination and ensuring that the test tube 4 remains sterile;

[0031] As shown in Figure 4 The sterilization assembly 6 further comprises a telescopic rod 610 arranged above the connecting plate 601 through a connecting frame, the telescopic end of the telescopic rod 610 is fixedly connected with an outer shell 603, the outer shell 603 is fixedly connected with a first motor 604, and the output end of the first motor 604 is fixedly connected with a fixed shell 605;

[0032] When encountering test tubes 4 of different depths, the worker can measure the depth of the air pipe 602 and the air pipe 608 in advance, and then adjust the height of the air pipe 608 through the telescopic rod 610, which can effectively prevent the problem of affecting the culture medium when the air pipe 608 is lowered due to mismatching of the position;

[0033] One side of the drive member 5 is provided with a hot air device 8, the air outlet end of the hot air device 8 is in communication with a second air pump through a pipeline, the air outlet end of the second air pump is in communication with a double-tube pipe, and the two ends of the double-tube pipe of the second air pump are respectively in communication with the air pipe 602 and the air pump;

[0034] The hot air device 8 is a hot air sterilizer, and the specific name and model can be different according to different manufacturers. Some common brands and models include Thermo Scientific Steri-Dry or Labotec Hot Air Sterilizer. Its working principle is to generate a high-temperature airflow through an electric heating element, and this high-temperature airflow can achieve the effect of killing bacteria, viruses and other microorganisms. The temperature of the hot air sterilizer can be adjusted between 160°C and 180°C, which is suitable for waterless sterilization. When the hot air passes through the surface of the test tube 4, the water on the surface evaporates rapidly and the temperature rises, so that the bacteria, fungi and other microorganisms are killed in the high-temperature environment. The device is controlled by setting the temperature and time to ensure the reliability of the sterilization process;

[0035] It should be noted that before the high-temperature airflow of the hot air device 8 is used to sterilize the test tube 4, the culture medium needs to be cooled, which can effectively avoid the influence of the high-temperature airflow on the culture medium;

[0036] The middle part of the chassis 1 is hollow, the second motor 7 is arranged in the hollow part of the chassis 1, the output end of the second motor 7 penetrates to the outside of the chassis 1 and is fixedly connected with the rotating disc 2, the surface of the rotating disc 2 is hingedly connected with the placing shell 3, and the test tube 4 is located in the placing shell 3; a chute is formed in one side of the chassis 1, and a ball is arranged below the placing shell 3 and in contact with the chassis 1;

[0037] Working principle: in specific use, first, the staff places the test tube 4 in the placing shell 3, and then the second motor 7 is turned on to rotate the test tube 4 through the rotating disc 2, when the test tube 4 is transferred to the position of the chute by the placing shell 3, the staff can tilt the test tube 4 and fill the culture medium in the test tube 4, when the test tube 4 filled with the culture medium rotates, the lower part of the sterilization assembly 6 is driven by the driving part 5, at this time, the air pipe 602 in the connecting plate 601 is sleeved on the outer surface of the test tube 4, the fixed shell 605 and the external shell 609 enter the test tube 4, then the driving part 5 is turned on to drive the sterilization assembly 6 to move downward, at this time, the hot air device 8 is turned on, the second air pump sends the hot flow in the hot air device 8 to the air pipe 602 and the air pipe 608 respectively, at this time, the air pipe 602 and the air pipe 608 can blow the sterilization hot flow to the inner and outer surfaces of the test tube 4 at the same time, which can achieve the effect of omnidirectional sterilization of the test tube 4, when the driving part 5 moves downward to a certain position and returns, the pipeline valve connected with the air bag 607 is opened, at this time, the first air pump 606 injects air into the air bag 607, so that the air bag 607 expands between the two plane parts of the fixed shell 605 and the external shell 609 and extends outward, until the surface of the air bag 607 is attached to the inner wall of the test tube 4, at this time, the air bag 607 rises with the driving part 5 and can wipe the inner wall of the test tube 4, which can effectively reduce the microbial pollution on the hands or tools of the operator, thereby reducing the risk of cross contamination and ensuring that the test tube 4 remains sterile;
