Description

Technical Field

[0001] This utility model relates to the technical field of microbial culture storage equipment, specifically to a constant-temperature biological culture preservation structure. Background Technology

[0002] Microbial resources used as biocatalysts mainly include four categories of microorganisms: bacteria, actinomycetes, yeasts, and molds. Through metabolism, they can effectively promote the extraction and transformation of plant-derived active ingredients. In industrial applications, it is necessary to selectively isolate target strains from the abundant microbial resources in nature. After obtaining highly efficient strains through multi-level screening, their production performance is improved through genetic modification, and standardized strain banks are established for long-term preservation. Although existing strain preservation technologies vary in specific operations, they all follow the core principle of reducing the metabolic activity of strains. By inhibiting cellular physiological activities, the genetic characteristics of strains are stably maintained, thereby extending the survival period and controlling the gene mutation rate, thus ensuring the supply of strains for industrial production.

[0003] In microbiology experiments, aseptic technique is the primary measure to prevent contamination. When performing operations such as inoculation and culture medium preparation, laboratory personnel must strictly follow aseptic procedures, such as wearing sterile gloves and using an alcohol lamp to flame the inoculation loop, to prevent microorganisms in the air or bacteria on their hands from contaminating the culture medium and inoculum.

[0004] Traditional microbial culture preservation devices have several problems. The internal space of the incubator is limited, and the microorganisms are usually stored in test tubes or slant agar. These containers are not easy to remove individually inside the incubator, requiring frequent opening of the incubator door. This not only affects the constant temperature environment inside the incubator but also increases the risk of microbial contamination. They cannot meet the different preservation requirements of different microbial cultures. Alternatively, storing the entire culture in the same storage device increases the risk of cross-contamination, and when retrieving samples, time is spent checking labels and selecting the required samples. Utility Model Content

[0005] To address the aforementioned issues, this invention provides a constant-temperature biological strain preservation structure. The sample cabinet serves as the main body of the entire preservation structure, and its interior is divided into several chambers. These chambers provide independent spaces for the preservation of different biological strains, thus avoiding cross-contamination between strains.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A constant temperature biological strain preservation structure includes a sample cabinet, the inner wall of which is provided with several chambers, and each chamber is provided with several incubators for placing samples.

[0007] The bottom wall of the incubator is fixedly connected with an insulation layer, and the insulation layer is provided with several slots. The bottom wall of each slot is provided with an ejection component for ejecting the sample, and the outside of each slot is provided with a cooling plate.

[0008] The incubator includes a top cover, which has several top holes corresponding to slots, and each top hole is hinged with a corresponding hole cover.

[0009] The technical principle of the above solution is as follows: Through the design of the sample cabinet and chambers, the classification, storage, and protection of biological bacterial samples are achieved. The sample cabinet, as the main structure, is scientifically divided into multiple chambers, each capable of independently storing different types of biological bacterial strains, effectively avoiding cross-contamination between strains.

[0010] By setting up a fixed insulation layer inside the incubator, the impact of external temperature fluctuations on the culture preservation environment is reduced, ensuring that the culture is preserved under constant temperature conditions.

[0011] By combining slots and pop-out components, convenient storage and retrieval of bacterial samples are achieved. The slot design allows the samples to be placed securely in the incubator, while the addition of pop-out components makes it easy to pop out the samples when they need to be removed, thus improving work efficiency.

[0012] The use of cooling elements enables precise temperature control within the incubator. These elements allow for temperature adjustment as needed, ensuring the microorganisms are stored at their optimal preservation temperature, thus extending their survival time and activity.

[0013] The design of the top cover and the perforated cover facilitates sample storage and retrieval while also preventing external contamination from entering the incubator to a certain extent.

[0014] The above approach has the following beneficial effects:

[0015] 1. This solution, through the design of sample cabinets and chambers, enables the scientific classification and independent storage of biological strains. Each chamber can independently store different types of biological strains, effectively avoiding cross-contamination between strains. At the same time, the fixed insulation layer inside the incubator provides a stable and suitable storage environment for the strains, ensuring that the strains are stored under constant temperature conditions, thereby improving the survival rate and activity of the strains.

[0016] 2. The combination of slot and pop-out component in this solution allows the bacterial samples to be securely placed in the incubator while being easily popped out for easy access by operators. This design not only improves work efficiency but also significantly reduces the risk of sample damage during access, ensuring the integrity and usability of the bacterial samples.

[0017] 3. This solution achieves precise temperature control within the incubator through the use of cooling plates, ensuring that the bacterial strains are stored at the optimal preservation temperature. At the same time, the design of the top cover and perforated cover further protects the cleanliness and safety of the incubator's interior, preventing external contamination from entering and providing strong protection for the long-term preservation of the bacterial strains. These designs together ensure that the bacterial strains are preserved in a constant temperature, stable, and safe environment, providing reliable support for biological experiments and research.

[0018] Furthermore, the pop-out component includes an electromagnet, with several springs fixedly connected to the top of each electromagnet, and the other end of each spring fixedly connected to a support block. A first buffer pad is fixedly connected to the top of each support block.

[0019] Beneficial effects: The combination of electromagnet and spring design enables rapid and stable ejection of bacterial samples, greatly improving storage and retrieval efficiency. The first buffer pad and the spring's cushioning effect reduce the risk of sample damage during ejection, ensuring the integrity and usability of the bacterial samples. The support block design allows the samples to be placed stably in the incubator, preventing shaking and displacement during storage and enhancing the stability of the storage structure.

[0020] Furthermore, the input terminals of the electromagnets are all connected to the output terminals of the controller, and the input terminals of the cooling chips are all connected to the output terminals of the controller.

[0021] Beneficial effects: The precise control of the electromagnet by the controller makes the sample storage and retrieval process faster and smoother, improves storage and retrieval efficiency, reduces the workload of operators, and achieves precise control of the temperature inside the incubator by controlling the cooling plate, ensuring that the bacteria are stored at the optimal storage temperature.

[0022] Furthermore, each of the top of the insulation layer is equipped with several indicator lights, and each indicator light corresponds to an adjacent slot. The input terminals of the indicator lights are all connected to the output terminals of the controller.

[0023] Beneficial effects: Indicator lights allow operators to visually monitor the preservation status of bacterial samples in each slot, such as whether the temperature is within the appropriate range and whether the sample has been removed. This visibility helps reduce operational errors and improves work efficiency. Since each indicator light corresponds to a slot, operators can quickly locate the slot requiring operation without having to search through multiple slots. This greatly simplifies the operation process and improves ease of use.

[0024] Furthermore, each chamber within the sample cabinet is equipped with a heat insulation layer.

[0025] Beneficial effects: The insulation layer effectively blocks heat transfer between chambers, allowing each chamber to maintain a relatively independent temperature environment. This helps reduce the impact of external temperature fluctuations on the preservation status of bacterial samples within the chambers and improves temperature stability. By setting up the insulation layer, the energy consumption of the refrigeration or heating system can be reduced.

[0026] Furthermore, the inner walls of the sample cabinets are all equipped with insulation layers.

[0027] Beneficial effects: The insulation layer effectively blocks the transfer of heat between the inside and outside of the sample cabinet, making the temperature inside the sample cabinet more stable and reducing the impact of external temperature fluctuations on the internal temperature environment. By setting up the insulation layer, the cooling or heating system of the sample cabinet does not need to work frequently to maintain the internal temperature, thereby reducing energy consumption.

[0028] Furthermore, each sample cabinet has several openings on one side corresponding to the chamber, and each opening has a cabinet door, which is fixedly connected to one end of the incubator.

[0029] Beneficial effects: The cabinet door design allows operators to easily access and manage the bacterial samples in each chamber. This design reduces operation time and improves work efficiency. When the cabinet door is closed, it effectively prevents the entry of outside air and microorganisms. This helps maintain a sterile environment within the chambers and reduces the risk of bacterial sample contamination.

[0030] Furthermore, the controller input is fixedly connected to the outer wall of the sample cabinet.

[0031] Beneficial effects: The controller allows for quick selection of the sample to be retrieved without having to search through multiple slots, greatly simplifying the operation process and improving ease of use. In addition, the controller can control the electromagnet to push out and retrieve the sample, and can also control the working state of the cooling chip to keep the sample at the same temperature for preservation.

[0032] Furthermore, several handles are fixedly connected to the side of the cabinet door away from the incubator, and each handle has an anti-slip layer.

[0033] Beneficial effects: The handle design allows operators to easily grip and open or close the cabinet door without pulling or pushing the edge of the door, which greatly improves the convenience and efficiency of operation and reduces the risk of damage to the cabinet door or sample cabinet due to improper operation. The handle and anti-slip layer design not only improve the convenience and safety of operation.

[0034] Furthermore, a second buffer pad is fixedly connected to the side of the incubator away from the cabinet door.

[0035] Beneficial effects: The design of the second buffer pad can effectively absorb and disperse the impact force from the outside, preventing the incubator from affecting the accuracy of the samples due to accidental collisions or vibrations. The material of the second buffer pad usually has a certain degree of elasticity and wear resistance, which can effectively prevent the surface of the incubator from being damaged by scratches or impacts.

[0036] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] The following detailed description illustrates the specific implementation method:

[0046] Example 1:

[0047] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown: A constant temperature biological strain preservation structure includes a sample cabinet 1, the inner wall of the sample cabinet 1 is provided with several chambers, and several incubators 2 for placing and storing samples are slidably fitted on the inner wall of each chamber; the bottom wall of each incubator 2 is fixedly connected with a heat insulation layer 8, and several slots 9 are opened on each heat insulation layer 8. The slots 9 are used to guide the samples to be placed in the correct position. The bottom wall of each slot 9 is provided with a pop-out component for ejecting the samples. The pop-out component makes it easier and faster to take out the samples. Cooling plates 10 are welded to the outside of each slot 9, which helps to extend the storage period of the samples and ensure the stability of the ambient temperature.

[0048] The incubator 2 includes a top cover 6, and each top cover 6 is provided with several top holes 7 corresponding to the slots 9. The top holes 7 guide the handling and storage of samples, increasing work efficiency. Each top hole 7 is hinged with a corresponding hole cover 5. The hole cover 5 can effectively prevent cross-contamination caused by accident when handling and storing samples.

[0049] Each chamber in the sample cabinet 1 is equipped with a heat insulation layer 4, which effectively blocks heat transfer between the chambers, allowing each chamber to maintain a relatively independent temperature environment. This helps to reduce the impact of external temperature fluctuations on the preservation status of bacterial samples in the chamber.

[0050] The inner walls of the sample cabinet 1 are all equipped with a heat insulation layer 8. By setting the heat insulation layer 8, the temperature inside the sample cabinet 1 is more stable, reducing the impact of external temperature fluctuations on the internal temperature environment. Each side of the sample cabinet 1 is equipped with several openings corresponding to the chambers, and each opening is equipped with a cabinet door 3. The design of the cabinet door 3 allows operators to easily access and manage the bacterial samples in each chamber. This design reduces operation time and improves work efficiency.

[0051] The specific implementation process is as follows: When the staff prepares to store the samples, they first open the cabinet door 3 smoothly and pull the incubator 2. Then, they check whether the corresponding hole cover 5 of each top hole 7 on the top cover 6 is open, check whether the pop-up component is in the released state, observe the data through the operation of the cooling plate 10, and confirm whether the chamber temperature is a suitable temperature for storing the samples. After confirmation, the staff guides the sample through the top hole 7, places the sample stably into the slot 9, and closes the cabinet door 3 smoothly.

[0052] Example 2:

[0053] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the difference from Example 1 is that the input terminals of the electromagnets 15 are all connected to the output terminals of the controller 11. The precise control of the electromagnets 15 by the controller 11 makes the sample storage and retrieval process faster and smoother, improves the storage and retrieval efficiency, and reduces the workload of the operators. The input terminals of the cooling plates 10 are all connected to the output terminals of the controller 11. The precise control of the temperature inside the incubator 2 by the controller 11 on the cooling plates 10 ensures that the bacteria are stored at the optimal storage temperature.

[0054] The top of the insulation layer 8 is equipped with several indicator lights 12, and each indicator light 12 corresponds to an adjacent slot 9. The input terminals of the indicator lights 12 are connected to the output terminals of the controller 11. Through the prompts of the indicator lights 12, the operator can intuitively see the preservation status of the bacterial samples in each slot 9, such as whether the temperature is within the appropriate range, whether the sample has been taken out, etc. This visibility helps to reduce operational errors and improve work efficiency.

[0055] The input terminal of the controller 11 is fixedly connected to the outer wall of the sample cabinet 1. By using the controller 11, the sample to be taken out can be selected quickly without having to search back and forth between multiple slots 9, which greatly simplifies the operation process and improves the convenience of operation. At the same time, the controller 11 can control the electromagnet 15 to push out and retrieve the sample, and can also control the working state of the cooling chip 10 to keep the sample at the same temperature for preservation.

[0056] The specific implementation process is as follows: After the staff has stored the sample, the controller 11 is activated, and the controller 11 controls the electromagnet 15 to work. The electromagnet 15 attracts the sample and puts it stably into the slot 9. The indicator light 12 corresponding to each slot 9 is observed to check whether the corresponding sample is stored properly. Then, the controller 11 controls the cooling chip 10 to adjust the ambient temperature to a threshold suitable for sample storage and preserve the sample.

[0057] Example 3:

[0058] As attached Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the difference from Embodiment 2 is that the ejection assembly includes an electromagnet 15, with several springs 16 fixedly connected to the top of each electromagnet 15. The other end of each spring 16 is fixedly connected to a support block 14. Through the combined design of the electromagnet 15 and the springs 16, the bacterial sample is ejected quickly and smoothly, greatly improving storage and retrieval efficiency. A first buffer pad 13 is fixedly connected to the top of each support block 14. The first buffer pad 13 and the buffering effect of the springs 16 together reduce the risk of sample damage during ejection, ensuring the integrity and usability of the bacterial sample. The cabinet door 3 is further away from the support block. Several handles are fixedly connected to one side of the incubator 2, and each handle has an anti-slip layer. The handle design allows the operator to easily grasp and open or close the cabinet door 3 without pulling or pushing the edge of the cabinet door 3. This greatly improves the convenience and efficiency of operation and reduces the risk of damage to the cabinet door 3 or sample cabinet 1 due to improper operation. A second buffer pad 17 is fixedly connected to the side of the incubator 2 away from the cabinet door 3. The design of the second buffer pad 17 can effectively absorb and disperse the impact force from the outside, preventing the accuracy of the samples from being affected by accidental collisions or vibrations.

[0059] The specific implementation process is as follows: When the staff needs to take out the sample, they can directly select the coordinates of the sample to be taken out through the control interface of the controller 11, and then smoothly open the cabinet door 3. At this time, the electromagnet 15 under the slot 9 corresponding to the selected sample will be de-energized, and the sample will be smoothly ejected by the action of the spring 16 in the slot 9. Then the sample is sent out after the hinged hole cover 5 on the top hole 7 is opened. After the staff successfully takes out the sample, the current cabinet door 3 should be closed to ensure that the temperature in the chamber remains stable.

[0060] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
