[0038] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] The present invention provides a microorganism detection device and a microorganism detection method. Figure 1-17 As shown, the microorganism detection device includes: an annular cylinder 1, the top and bottom of which are respectively fixedly mounted with an upper cover 2 and a lower cover 3, so that they form a closed box body for culturing microorganisms; a storage turntable 4, which is rotatably mounted in the annular cylinder 1, and the outer ring of the storage turntable 4 is tightly fitted with the inner wall of the annular cylinder 1; a driving motor 5, which is fixedly mounted on the top of the lower cover 3, and the output shaft of the driving motor 5 is fixedly connected to the bottom center of the storage turntable 4, and is used to drive the storage turntable 4 to rotate in the annular cylinder 1; a plurality of isolation storage covers 6 are fixedly mounted on the top of the storage turntable 4 for placing culture dishes 8, and the isolation storage covers 6 rotate with the storage turntable 4, and the openings of the plurality of isolation storage covers 6 are all facing the inner wall direction of the annular cylinder 1. The ring tube 1 is provided with a plurality of isolation storage covers 6, and the tops of the isolation storage covers 6 are fixedly mounted with closed top covers 7, so that the isolation storage covers 6, the closed top covers 7 and the inner wall of the ring tube 1 constitute an independent storage cavity for storing the culture dish 8, and the plurality of storage cavities are not connected to each other. A take-in and put-out port 9 is provided on one side of the ring tube 1, and the take-in and put-out port 9 is arranged corresponding to the opening of the isolation storage cover 6, and is used for taking and putting the culture dish 8. An openable door panel 10 is provided on the outside of the ring tube 1 for controlling the opening and closing of the take-in and put-out port 9. A receiving plate 11 is fixedly mounted on the outside of the ring tube 1 on one side of the take-in and put-out port 9 for temporarily placing the culture dish 8; a hot air supply mechanism is arranged on the storage turntable 4, and is used for providing heat required for microbial culture to the plurality of storage cavities.

[0040] In this embodiment, when in use, first open the door panel 10 outside the ring tube 1 to expose the access port 9. Then, the user can put the culture dish 8 into the corresponding isolation storage cover 6 through the access port 9. Each isolation storage cover 6 constitutes an independent storage chamber, and the top is closed by the closed top cover 7, which ensures the stability and independence of the culture dish 8 during the rotation process. Then, close the door panel 10, start the drive motor 5, and the output shaft of the drive motor 5 drives the storage turntable 4 to rotate in the ring tube 1, so that multiple isolation storage covers 6 and the culture dishes 8 therein rotate accordingly, so as to achieve uniform heating and the need to adjust the position when taking and placing the culture dishes 8. The hot air supply mechanism provides the heat required for microbial culture to multiple storage chambers to ensure that the microorganisms grow in a suitable temperature environment. When the culture dish 8 needs to be taken out for testing, open the door panel 10 again, and temporarily place the culture dish 8 on the receiving plate 11 through the access port 9 to complete the access operation.

[0041] This solution not only improves the space utilization rate of microbial culture by designing a storage turntable 4 with multiple isolation storage covers 6 and realizing rotation in the ring tube 1, but also enables each culture dish 8 to be cultured in an independent storage chamber, avoiding mutual interference. At the same time, the opening of the isolation storage cover 6 extends toward the inner wall of the ring tube 1 and fits tightly with the inner wall, effectively preventing heat loss and interference from the external environment, and also avoiding mutual influence between the storage chambers when taking and placing, ensuring the stability and accuracy of the microbial culture environment.

[0042] In addition, the heat required for microbial cultivation is provided to the multiple storage chambers through the hot air supply mechanism, thereby realizing accurate control of the microbial cultivation temperature. In conjunction with the rotation function of the drive motor 5, the heating of the culture dish 8 can be controlled. At the same time, the design of the access plate 11 also facilitates the operation of the user when taking and placing the culture dish 8, thereby improving the convenience and safety of use.

[0043] In summary, the microbial detection device described in this scheme can solve the problem of heat loss during taking and affecting the cultivation of other culture dishes in the prior art, and has the advantages of compact structure, convenient use, stable culture environment, high culture efficiency and high accuracy.

[0044] In a further preferred embodiment of the present invention, the hot air supply mechanism includes two air isolation rings 12 arranged at the bottom of the storage turntable 4, the air isolation ring 12 located on the outside is fixedly connected to the inner wall of the ring tube 1, the tops of the two air isolation rings 12 are in close contact with the bottom of the storage turntable 4, the bottoms of the two air isolation rings 12 are fixedly installed with the same closed ring 13, the two air isolation rings 12 and the closed ring 13 constitute a hot air guide channel, and the top of the lower cover 3 is fixedly installed with a hot air supply fan 14. The air inlet pipe 15 of the hot air supply fan 14 extends to the outside of the ring tube 1 and is installed with a filter head 16. The air outlet pipe 17 of the hot air supply fan 14 is fixedly connected to the bottom of the closed ring 13. An air inlet hole 18 is provided at the connection between the closed ring 13 and the air outlet pipe 17, which is used to introduce hot air into the hot air guide channel. A plurality of conducting holes 19 are provided on the storage turntable 4. The plurality of conducting holes 19 are respectively arranged corresponding to a plurality of isolation storage covers 6, which are used to introduce the hot air in the hot air guide channel into the storage cavity to provide the heat required for microbial culture.

[0045] In this embodiment, the hot air supply mechanism mainly includes two air isolation rings 12, which are arranged at the bottom of the storage turntable 4 and are tightly fitted with the inner wall of the ring tube 1 and the bottom of the storage turntable 4. The two air isolation rings 12 and the closed ring 13 at the bottom together constitute a hot air guide channel. The hot air supply fan 14 is installed on the top of the lower cover 3, and its air inlet pipe 15 extends to the outside of the ring tube 1, and is equipped with a filter head 16 to filter external impurities. The air outlet pipe 17 of the hot air supply fan 14 is fixedly connected to the bottom of the closed ring 13, and the hot air is introduced into the hot air guide channel through the air inlet hole 18. A plurality of conduction holes 19 are provided on the storage turntable 4, and these conduction holes 19 correspond one by one to the isolation storage cover 6, so that the hot air can be introduced into the storage cavity from the hot air guide channel to provide the required heat for microbial culture.

[0046] The hot air supply mechanism design in this embodiment realizes the directional flow and uniform distribution of hot air through the hot air guide channel composed of two air isolation rings 12 and a closed ring 13. The hot air supply fan 14 inhales and heats the outside air through the filter head 16, and then introduces the hot air guide channel through the air outlet pipe 17 and the air inlet 18. This design not only improves the utilization efficiency of hot air, but also ensures that the hot air can be evenly distributed in each storage cavity, providing a stable and suitable growth environment for microorganisms. At the same time, the use of the filter head 16 also effectively prevents the interference of external impurities on the cultivation of microorganisms.

[0047] In a further preferred embodiment of the present invention, a sealing plate 20 is fixedly installed between the two air isolation rings 12, and the setting position of the sealing plate 20 corresponds to the access port 9. The top of the sealing plate 20 is in sliding contact with the bottom of the storage turntable 4, and is used to close the conductive hole 19 rotated to the position of the access port 9. The width of the sealing plate 20 is larger than the aperture of the conductive hole 19 by 0.5 to 1 cm.

[0048] In this embodiment, a sealing plate 20 is fixedly installed between the two air isolation rings 12. The sealing plate 20 is set at a position corresponding to the access opening 9. When the object placing turntable 4 rotates to the access opening 9, the sealing plate 20 can seal the conduction hole 19 at the corresponding position, thereby preventing hot air from leaking out of the conduction hole 19 when the culture dish 8 is taken in and placed. The width of the sealing plate 20 is designed to be 0.5 to 1 cm larger than the aperture of the conduction hole 19, so as to ensure that the conduction hole 19 can be completely sealed and maintain good sliding contact.

[0049] The introduction of the sealing plate 20 significantly improves the sealing and stability of the hot air supply mechanism. When taking or placing the culture dish 8, since the sealing plate 20 can seal the conduction hole 19 rotated to the position of the take-in and place-out port 9, it can effectively prevent hot air from leaking out of the conduction hole 19, thereby avoiding heat loss and interference from the external environment.

[0050] In a further preferred embodiment of the present invention, a sub-controller 21, a temperature sensor 22 and a high-definition camera 23 are fixedly installed on the plurality of closed top covers 7. The sub-controller 21 is connected to the temperature sensor 22 and the high-definition camera 23. The temperature sensor 22 is used to detect the culture temperature in the storage chamber, and the high-definition camera 23 is used to monitor the cultivation status of microorganisms in the transparent material culture dish 8.

[0051] In this embodiment, a sub-controller 21, a temperature sensor 22 and a high-definition camera 23 are fixedly installed on the multiple closed top covers 7. The sub-controller 21 is connected to the temperature sensor 22 and the high-definition camera 23, and the real-time monitoring of the culture temperature in the storage chamber and the monitoring of the microorganism cultivation status in the transparent material culture dish 8 are realized, and an external display can be used. Through this design, the user can understand the cultivation status of the microorganisms anytime and anywhere, and adjust the cultivation conditions as needed.

[0052] The introduction of the temperature sensor 22 enables us to monitor the culture temperature in the storage chamber in real time, thereby ensuring that the microorganisms grow in a suitable temperature environment. This design not only improves the efficiency and accuracy of microbial culture, but also enables users to accurately control the culture conditions according to the temperature data to meet the culture requirements of different microorganisms. At the same time, the real-time recording and storage of temperature data also provides strong support for subsequent data analysis and research.

[0053] The addition of the high-definition camera 23 enables remote monitoring of the cultivation status of microorganisms in the transparent material culture dish 8. Through the high-definition camera 23, the user can clearly observe key information such as the growth of the microorganisms, morphological changes, and whether they are contaminated. This design not only improves the efficiency and accuracy of microbial detection, but also enables users to promptly discover and deal with problems that may arise during the cultivation process, thereby avoiding unnecessary losses and risks. In addition, the remote monitoring function of the high-definition camera 23 also enables users to understand the cultivation status of microorganisms anytime and anywhere, greatly improving work efficiency and convenience.

[0054] In a further preferred embodiment of the present invention, a plurality of the closed top covers 7 are movably embedded with a cover ball 24 on their inner sides, and the cover ball 24 is in contact with the lid of the culture dish 8 .

[0055] In this embodiment, a capping ball 24 is movably embedded on the inner side of each of the plurality of closed top covers 7. The capping ball 24 contacts the lid of the culture dish 8 and can provide uniform pressure when the closed top cover 7 is closed, ensuring that the lid of the culture dish 8 is tightly closed. This design not only improves the sealing performance of the closed top cover 7, but also enables the user to operate more easily and smoothly when closing the closed top cover 7.

[0056] In a further preferred embodiment of the present invention, a master controller 25 is provided on the outer side of the ring tube 1 , and the master controller 25 is connected to the drive motor 5 , the hot air supply blower 14 and a plurality of sub-controllers 21 .

[0057] In this embodiment, a master controller 25 is provided outside the ring tube 1, and the master controller 25 is connected to the drive motor 5, the hot air supply fan 14 and the plurality of sub-controllers 21. Through the master controller 25, the user can realize the centralized control and remote monitoring of the entire microorganism detection device. This design not only improves the automation level of the device, but also enables the user to manage and operate the entire system more conveniently.

[0058] In a further preferred embodiment of the present invention, the upper surface of the receiving plate 11 is located in the same plane as the lower wall of the access port 9 and the upper surface of the storage turntable 4, and the upper surface of the receiving plate 11 is in contact with or separated from the bottom surface of the door panel 10.

[0059] In this embodiment, the receiving plate 11 is positioned so that its upper surface is in the same plane as the lower wall of the access opening 9 and the upper surface of the storage turntable 4. This design enables the receiving plate 11 to smoothly fit or separate from the bottom surface of the door panel 10 when the door panel 10 is opened or closed, thereby ensuring the sealing of the access opening 9 and the convenience of operation.

[0060] In a further preferred embodiment of the present invention, an anti-slip enclosure 26 is fixedly installed on the upper surface of the receiving plate 11 for placing and protecting the culture dish 8 , and a buffer pad 27 is fixedly installed on the inner side of the anti-slip enclosure 26 .

[0061] In this embodiment, an anti-slip enclosure 26 is fixedly installed on the upper surface of the access plate 11, and the anti-slip enclosure 26 is used to provide additional protection when the culture dish 8 is placed to prevent the culture dish 8 from slipping or being damaged during the process of taking or transporting. At the same time, a buffer pad 27 is fixedly installed on the inner side of the anti-slip enclosure 26 to increase the protection of the culture dish 8 and reduce the damage caused by collision or friction.

[0062] In a further preferred embodiment of the present invention, a plurality of assembly grooves 28 are provided on the inner wall of the ring tube 1 , and a germicidal lamp 29 is fixedly installed in each of the plurality of assembly grooves 28 , and the germicidal lamp 29 is arranged away from the access opening 9 .

[0063] In this embodiment, a plurality of assembly grooves 28 are provided on the inner wall of the ring tube 1, and sterilizing lamps 29 are fixedly installed in these assembly grooves 28. The arrangement positions of these sterilizing lamps 29 avoid the access opening 9 to ensure that no harm is caused to the operator during the sterilization process, while effectively sterilizing the microorganism culture environment in the storage chamber.

[0064] The introduction of the germicidal lamp 29 significantly improves the sterilization effect inside the ring tube 1. Since the germicidal lamp 29 can emit strong ultraviolet rays or ozone and other sterilizing substances, it can quickly kill bacteria, viruses and other microorganisms in the storage chamber, thereby ensuring the cleanliness and sterility of the microbial culture environment. This design not only improves the accuracy and reliability of microbial culture experiments, but also reduces the risk of experimental failure caused by microbial contamination.

[0065] In order to further improve the use effect of the device, in addition to the above scheme, this scheme also has the following embodiments:

[0066] In another embodiment of the present invention, a plurality of the isolation storage covers 6 are provided with a dish body fixing and unlocking pop-up mechanism for fixing the culture dish 8 placed therein and automatically popping out when the culture dish 8 is taken out, and the dish body fixing and unlocking pop-up mechanism comprises: a rectangular sliding opening 30 opened on both sides of the same isolation storage cover 6, and locking blocks 31 are slidably installed in the two rectangular sliding openings 30 for fixing the placed culture dish 8, and rectangular openings 32 are opened on the two locking blocks 31, and U-shaped guide frames 33 are slidably installed in the two rectangular openings 32, and the two U-shaped guide frames 33 are respectively fixedly connected to the two sides of the isolation storage cover 6, and stable guide rods 34 that slide through the corresponding U-shaped guide frames 33 are fixedly installed in the two rectangular openings 32, and reset springs are slidably sleeved on the two stable guide rods 34 35, the two ends of the reset spring 35 respectively conflict with the inner wall of the rectangular opening 32 and the U-shaped guide frame 33, and are used to reset the locking block 31 after sliding. A connecting strip 36 is fixedly installed on one of the two locking blocks 31, and a guide frame 37 is fixedly installed on the outside of the isolation storage cover 6.

A stabilizing block 41 is fixedly installed at the position of the storage turntable 4 corresponding to the notch 39, and a pop-up spring 42 is fixedly installed between the stabilizing block 41 and the dish body ejection block 40, which is used to lock the block 31 to unlock the opening and eject the culture dish 8.

[0067] In this embodiment, a dish body fixing and unlocking pop-up mechanism is added to multiple isolation storage covers 6, which is intended to achieve a stable fixation of the culture dish 8 placed therein, and automatically pop it out when it needs to be taken out, which is convenient for the user's operation. Specifically, the dish body fixing and unlocking pop-up mechanism includes a rectangular sliding opening 30 opened on both sides of the isolation storage cover 6, a locking block 31 slidably installed in the rectangular sliding opening 30, and a series of auxiliary reset and pop-up components. The locking block 31 realizes the sliding and reset functions through a rectangular through opening 32, a U-shaped guide frame 33, a stable guide rod 34 and a reset spring 35. At the same time, components such as a connecting strip 36, a guide frame 37, and a synchronous belt 38 are used to realize the synchronous movement of two locking blocks 31. When it is necessary to take out the culture dish 8, the locking block 31 will slide and release the culture dish 8 through the unlocking mechanism, and at this time the pop-up spring 42 will push the dish body pop-up block 40 to pop the culture dish 8 out of the notch 39.

[0068] The introduction of the dish body fixing and unlocking ejection mechanism significantly improves the stability and safety of the culture dish 8 in the isolation storage cover 6. The locking block 31 can effectively fix the culture dish 8 to prevent it from slipping or being damaged during rotation or transportation. At the same time, the design of components such as the reset spring 35 and the synchronous belt 38 makes the sliding and reset process of the locking block 31 smoother and more reliable, thereby ensuring the stability and durability of the mechanism.

[0069] In addition, the dish body fixing and unlocking ejection mechanism also greatly improves the user's convenience. When the culture dish 8 needs to be taken out, the user only needs to unlock the mechanism, and the culture dish 8 will automatically pop out from the notch 39, without the user having to take it out manually, thereby saving time and energy. This design not only improves work efficiency, but also reduces the difficulty of operation, allowing users to more easily manage and operate the entire microbial detection device.

[0070] In summary, the introduction and design of the dish body fixing and unlocking pop-up mechanism in this embodiment not only improves the stability and safety of the culture dish 8 in the isolation storage cover 6, but also greatly improves the user's convenience. This design is of great significance to improving the overall performance and user experience of the microbial detection device, and also provides users with a more efficient and convenient way of use.

[0071] In another embodiment of the present invention, the dish body fixing and unlocking pop-up mechanism also includes a pop-up trigger rod 43, which is fixedly mounted on a locking block 31 equipped with a connecting strip 36, and the pop-up trigger rod 43 is located at the top of the locking block 31 and outside the isolation storage cover 6. The top of the pop-up trigger rod 43 extends to a height higher than the closed top cover 7, and a pop-up trigger elastic sheet 44 is slidably mounted on the upper cover 2. The pop-up trigger elastic sheet 44 overlaps with the track of the pop-up trigger rod 43 when unlocked, and a connecting end sheet 45 is fixedly mounted on the top of the pop-up trigger elastic sheet 44. An adjusting screw 46 is rotatably mounted on the upper cover 2, and the adjusting screw 46 threadably penetrates the connecting end sheet 45, and is used to adjust whether the pop-up trigger elastic sheet 44 overlaps with the track of the pop-up trigger rod 43.

[0072] In this embodiment, the fixing and unlocking pop-up mechanism of the dish body is further improved, and components such as a pop-up trigger rod 43 and a pop-up trigger elastic sheet 44 are added. Specifically, the pop-up trigger rod 43 is fixedly mounted on the locking block 31 equipped with the connecting strip 36, and extends to the outside of the isolation storage cover 6, and its top end is higher than the closed top cover 7. At the same time, a pop-up trigger elastic sheet 44 is slidably mounted on the upper cover 2, and the elastic sheet has an overlapping portion with the unlocking track of the pop-up trigger rod 43. In addition, the position of the pop-up trigger elastic sheet 44 is adjusted by adjusting the screw 46 and the connecting end sheet 45 to ensure that it is accurately matched with the pop-up trigger rod 43.

[0073] The introduction of the pop-up trigger rod 43 and the pop-up trigger elastic sheet 44 makes the unlocking process of the dish body fixing and unlocking pop-up mechanism more flexible and reliable. When the user needs to take out the culture dish 8, he only needs to adjust the position of the pop-up trigger elastic sheet 44 by adjusting the screw 46 so that it coincides with the unlocking track of the pop-up trigger rod 43. When rotating, the pop-up trigger elastic sheet 44 will be triggered and push the pop-up trigger rod 43, thereby driving the locking block 31 to slide and release the culture dish 8. This design not only improves the automation of the mechanism, but also makes the unlocking process simpler and more intuitive.

[0074] In addition, the design of the adjustment screw 46 and the connecting end piece 45 provides the user with more operational flexibility. The user can adjust the position of the pop-up trigger elastic piece 44 according to actual needs to ensure that it accurately matches or does not match the pop-up trigger rod 43. This design not only improves the applicability and versatility of the mechanism, but also provides the user with a more personalized use experience.

[0075] In another embodiment of the present invention, the side of the upper cover 2 is fixedly mounted with an assembly shaft plate 47 located above the door panel 10, and a lifting screw 48 is rotatably mounted on the assembly shaft plate 47. The lifting screw 48 is threadedly connected to the door panel 10, and a threaded hole engaged with the lifting screw 48 is provided on the door panel 10. The driving of the lifting screw 48 is opposite to that of the adjusting screw 46, that is, the adjusting screw 46 drives the pop-up trigger elastic sheet 44 to descend, and then the lifting screw 48 drives the door panel 10 to move up. The pitch of the lifting screw 48 is different from that of the adjusting screw 46, that is, the adjusting screw 46 drives the pop-up trigger elastic sheet 44 to descend, and the lifting screw 48 drives the door panel 10 to move up. The screw 46 drives the pop-up trigger elastic sheet 44 to descend and coincide with the trajectory of the pop-up trigger rod 43, and the lifting screw 48 drives the door panel 10 to move up to fully open the access port 9. A driving motor 49 is fixedly installed on the top of the upper cover 2, and a synchronous wheel 50 is fixedly installed on the output shaft of the driving motor 49, the adjusting screw 46 and the lifting screw 48. The three synchronous wheels 50 are sleeved with the same driving belt 51, and two sliding rails 52 are fixedly installed on the outer side of the ring tube 1, and the two sliding rails 52 are respectively buckled on both sides of the door panel 10.

[0076] In this embodiment, the upper cover 2 and its periphery introduce components such as a lifting screw 48, an assembly shaft plate 47, a driving motor 49, a synchronous wheel 50 and a driving belt 51. Specifically, the assembly shaft plate 47 is fixedly mounted on the side of the upper cover 2, and the lifting screw 48 is rotatably mounted thereon. The lifting screw 48 is threadedly connected to the threaded hole on the door panel 10, and the door panel 10 can be driven to move up and down by rotating the lifting screw 48. At the same time, the driving direction of the lifting screw 48 and the adjusting screw 46 are opposite, and the pitch is different, so as to ensure that the opening degree of the door panel 10 can be accurately controlled while adjusting the position of the pop-up trigger elastic sheet 44. In addition, components such as a driving motor 49, a synchronous wheel 50 and a driving belt 51 are also introduced to realize the synchronous drive of the lifting screw 48 and the adjusting screw 46. At the same time, two sliding rails 52 are fixedly mounted on the outer side of the ring tube 1, which are used to buckle on both sides of the door panel 10 to improve the stability of the door panel 10.

[0077] The introduction of the lifting screw 48, the assembly shaft plate 47 and other components makes the opening and closing process of the door panel 10 more automated and accurate. Driven by the drive motor 49, the lifting screw 48 and the adjusting screw 46 can rotate synchronously, thereby realizing the opening of the door panel 10 and the adjustment of the position of the pop-up trigger elastic sheet 44. This design not only improves the degree of automation of the mechanism, but also makes the opening and closing process of the door panel 10 more stable and reliable. At the same time, the design of the sliding track 52 also improves the stability of the door panel 10, preventing it from shaking or deflecting during the opening and closing process.

[0078] In addition, the design that the lifting screw 48 and the adjusting screw 46 are driven in opposite directions and have different pitches also provides users with more operational flexibility. Users can adjust the opening degree of the door panel 10 and the position of the pop-up trigger elastic sheet 44 according to actual needs.

[0079] In another embodiment of the present invention, one side of the locking block 31 corresponding to the loading and unloading port 9 is an arc-shaped feeding guide surface 53, which is used to push the locking block 31 when the culture dish 8 is placed in, and the other side is an arc-shaped buckling surface 54, which is used to buckle on the outer edge of the culture dish 8 after the culture dish 8 is placed in.

[0080] In this embodiment, the locking block 31 has an arc-shaped introduction guide surface 53 on one side corresponding to the access opening 9, and an arc-shaped buckle surface 54 on the other side. The introduction guide surface 53 is designed to easily push the locking block 31 when the culture dish 8 is placed, so that the culture dish 8 can smoothly enter the isolation storage cover 6. The buckle surface 54 is used to buckle on the outer edge of the culture dish 8 after the culture dish 8 is placed, ensuring that it is firmly fixed in the isolation storage cover 6.

[0081] The design of the introduction guide surface 53 significantly improves the convenience of placing the culture dish 8. When the user places the culture dish 8 into the isolation storage cover 6, the introduction guide surface 53 only needs to gently push it, and the culture dish 8 will be guided to push the locking block 31 and enter the predetermined position. This design not only simplifies the operation steps, but also reduces the difficulty of operation, so that the user can complete the process of placing the culture dish 8 more easily.

[0082] In summary, compared with the related technology, the device can solve the problem of heat loss during taking and affecting the culture of other culture dishes in the prior art, and has the advantages of compact structure, convenient use, stable culture environment, high culture efficiency and high accuracy.

[0083] The present invention also includes a microbial detection method, which uses the above microbial detection device to perform culture detection, comprising the following steps:

[0084] Step 1: When cultivating the biological organisms, first open the door panel 10, and place the culture dishes 8 with microorganisms into the storage chambers corresponding to the multiple isolation storage covers 6 through the access opening 9 for cultivation. When placing the culture dishes 8, the culture dishes 8 slide in through the access plate 11. When the culture dishes 8 slide in, their outer edges contact the feeding guide surface 53, so that the locking block 31 is pushed open and the reset spring 35 is compressed. When the locking block 31 on one side slides, the sliding of the connecting strip 36 and the pulling of the synchronous belt 38 are used to synchronously open the other locking block 31, until the culture dishes 8 are placed in, and under the rebound of the reset spring 35, the outer edge of the culture dishes 8 contacts the buckling surface 54 for buckling and fixing. At this time, the culture dishes 8 compress the dish body ejection block 40 and the ejection spring 42. In use, the main controller 25 is used to control the rotation of the output shaft of the drive motor 5 to control the switching of the storage chamber. When the storage chamber with the culture dishes 8 rotates to one side, it passes through the sterilization lamp 29 for sterilization. After all the storage is completed, the door panel 10 is closed for sealing;

[0085] Step 2: During cultivation, if heating is required, the hot air supply fan 14 is started, so that the air is filtered by the filter head 16 and then sucked into the air inlet pipe 15, and then converted and heated by the hot air supply fan 14, and discharged into the air inlet hole 18 through the air outlet pipe 17, and finally enters the hot air guide channel formed by the two air isolation rings 12 and the closed ring 13, and then discharged into multiple storage cavities through the conducting holes 19, and the internal culture dishes 8 are heated to provide the heat required for cultivation. In use, the conducting holes 19 and the sealing plate 20 are controlled to allow air to enter the multiple storage cavities. When multiple storage cavities need hot air, the multiple conducting holes 19 are staggered with the sealing plate 20. During cultivation, the high-definition camera 23 monitors the situation inside the internal culture dish 8 at all times;

[0086] Step 3: If any culture dish 8 needs to be taken out for testing, the driving motor 49 is first started. Under the joint action of the synchronous wheel 50 and the driving belt 51, the adjusting screw 46 drives the pop-up trigger elastic sheet 44 to descend, and the lifting screw 48 drives the door panel 10 to rise and open, and the driving motor 5 is started to rotate the storage turntable 4 so that the opening of the isolation storage cover 6 corresponds to the access opening 9. At this time, the sealing plate 20 just covers the conductive hole 19 at the corresponding position, so that the corresponding storage cavity temporarily stops entering the air, so as to avoid a large amount of hot air leakage and avoid affecting the culture of other culture dishes 8. Then, the door panel 10 is opened to take out the culture dish 8 for testing. At this time, the driving motor 5 continues to drive the storage turntable 4 to rotate, so that the spring trigger elastic sheet 44 is pushed down and the lifting screw 48 drives the door panel 10 to rise and open. The pop-up trigger elastic sheet 44 contacts the pop-up trigger rod 43, so that the locking block 31 slides and unlocks, and the pop-up spring 42 rebounds, so that the dish body pop-up block 40 pops out of the culture dish 8. When taking out, the culture dish 8 is blocked by the anti-escape enclosure 26 and protected by the buffer pad 27. When continuing to rotate, the pop-up trigger elastic sheet 44 is slightly deformed and disengaged from the pop-up trigger rod 43, and the various parts of the locking block 31 are reset. When putting in, since the pop-up trigger elastic sheet 44 will be deformed, it will not affect the putting in. At the same time, the opening and closing height of the door panel 10 can also be opened and closed at a lower level, and the pop-up trigger elastic sheet 44 and the pop-up trigger rod 43 can be controlled not to overlap, thereby avoiding affecting the putting in of the culture dish 8 and avoiding rotation unlocking.
