[0002] Microbial culture is a basic technology in biological and medical research, and is widely used in scientific research, medical treatment, industry, and environmental monitoring. Microbial incubators are the core equipment for microbial culture, which are used to provide constant temperature, humidity, gas environment and other conditions to ensure efficient growth of microorganisms. Since there are various microorganisms in the ocean, including aerobic bacteria, facultative anaerobes and strict anaerobes, for aerobic bacteria, ordinary constant temperature incubators can be used to complete the culture, while for anaerobic bacteria, anaerobic incubators are required.

[0003] When culturing microorganisms, anaerobic incubators need to provide an oxygen-free environment and continuously introduce inert gas into the box to meet the needs of microbial cultivation. However, traditional anaerobic incubators are not very convenient to operate during the process of taking and placing culture solutions. The simple operation is to directly open the door to take and place. Although this operation is fast, the outside air can easily enter, and the inert gas in the box will also be discharged in large quantities. The complicated operation is to add an air lock chamber, transfer the culture solution to the chamber first, and then adjust the opening and closing of the internal and external doors to achieve the taking and placing of the culture solution.

[0025] In one aspect of the present embodiment, the placement rack includes a first vertical plate 23 and a second vertical plate 27 that are integrally connected. The first vertical plate 23 and the second vertical plate 27 are arranged at a right angle and are both attached to the top of the turntable 4, and the same placement plate 28 is fixedly connected between the inner sides. A placement groove 281 for placing a culture dish is provided on the top of the placement plate 28.

[0026] The microorganism culture box also includes a driving mechanism arranged on the outer wall of the bottom of the box body 1, which is used to drive the turntable 4 to rotate and adjust the position of the placement rack. The driving mechanism includes a mounting frame 10 fixedly connected to the outer wall of the bottom of the box body 1, and a driving motor 16 is fixedly connected to the top of the mounting frame 10. The output shaft of the driving motor 16 rotates through the bottom of the box body 1 and extends to the inside of the exhaust chamber 8. A pinion 17 is fixedly sleeved on the output shaft of the driving motor 16. A rotating sleeve 14 is fixedly connected to the bottom of the turntable 4. The bottom end of the rotating sleeve 14 rotates through the bottom wall of the box body 1 and extends downward. A large gear 19 meshing with the small gear 17 is fixedly sleeved on the outer wall of one side of the rotating sleeve 14 located inside the exhaust chamber 8. When the driving motor 16 is started, the rotating sleeve 14 can be driven to rotate through the meshing movement of the small gear 17 and the large gear 19, and then the turntable 4 can be driven to rotate, thereby realizing the rotation adjustment of the placement rack position.

[0027] The present invention can be used in the field of microbial culture for marine microbial detection, and can also be applied to other fields of the present invention. Example

[0028] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 9As shown, the microbial incubator also includes an exhaust mechanism arranged on the top of the turntable 4, and is connected to multiple groups of placement racks at the same time. The turntable 4 is driven to rotate by the driving mechanism, and the placement racks can be driven to rotate and move by the exhaust mechanism; the exhaust mechanism includes a piston cylinder 7 fixedly connected to the center position of the top of the turntable 4, and the top of the side wall of the piston cylinder 7 is annular and equidistantly fixedly connected with multiple multi-section telescopic tubes 13, and the telescopic ends of the multiple multi-section telescopic tubes 13 are respectively penetrated and fixedly connected with one side of the corresponding first vertical plate 23, and the multiple multi-section telescopic tubes 13 are all installed with a one-way air inlet valve, the top of the piston cylinder 7 is fixedly connected with an air guide pipe 9, and the other end of the air guide pipe 9 is fixedly penetrated through one side of the top of the turntable 4 and is connected with the exhaust chamber 8, and a one-way air outlet valve is installed on the air guide pipe 9, a piston assembly for extracting gas is provided in the piston cylinder 7, and an exhaust pipe 11 connected with the exhaust chamber 8 is fixedly connected to one side of the box body 1. When the placement rack composed of the first vertical plate 23 and the second vertical plate 27 is brought into the material taking box 5 by the material taking mechanism, it will contact and cooperate with the material taking mechanism and the top wall and side wall of the material taking box 5 to form a sealed space. At this time, the culture dish is placed in the placement groove 281 on the placement plate 28, so that the culture dish is located in the sealed space; because the multi-section telescopic tube 13 is provided, the multi-section telescopic tube 13 will automatically stretch and lengthen during the entire process of the placement rack entering the interior of the material taking box 5; when the placement rack moves to correspond to the access port 51, the culture dish can be taken out through the access port 51, and if a new culture dish needs to be put in to continue the culture, it can be put in again through the access port 51. Regardless of whether a new culture dish is put in to continue the culture or to continue the work of taking out, the placement rack needs to be pushed back to the turntable 4 through the material taking mechanism, and the multi-section telescopic tube 13 automatically shrinks and shortens; when the placement rack no longer corresponds to the access port 51, the blocking mechanism automatically closes the access port 51 to prevent a large amount of gas in the box 1 from leaking out. During the process of taking and placing materials, the outside air will enter the placement rack through the placement port 51 and exchange with the gas inside it. In order to avoid bringing the outside air into the box body 1, during the process of the placement rack moving back, it will contact and cooperate with the inner wall of the material taking box 5 to form a sealed space, and then the gas in the sealed space will be sucked into the piston cylinder 7 through the multi-section telescopic tube 13 through the piston assembly, and then transported from the air guide pipe 9 to the exhaust chamber 8, and finally discharged from the exhaust pipe 11 to the outside, and collected and processed in a centralized manner, so as to effectively avoid bringing the outside air into the culture chamber 6 and affecting the culture of other culture solutions.

[0029] In one aspect of the present embodiment, the piston assembly includes a piston block 15 sealingly and slidably connected in the piston cylinder 7, the bottom of the piston block 15 is fixedly connected to a piston rod 18, and the bottom end of the piston rod 18 passes through the top of the turntable 4 and slides through the interior of the rotating sleeve 14, the bottom end of the piston rod 18 extends to the bottom of the rotating sleeve 14 and is rotatably connected to a nut plate 20, the top of the mounting frame 10 is rotatably connected to a reciprocating screw 22, the nut plate 20 is threadedly sleeved on the reciprocating screw 22, the bottom outer wall of the box body 1 is fixedly connected to a first screw motor 21, and the output end of the first screw motor 21 is fixedly connected to the top of the reciprocating screw 22. When the placement rack is pushed back to the culture chamber 6 by the material taking mechanism, the first screw motor 21 is started and drives the reciprocating screw 22 to rotate, and at the same time drives the nut plate 20 to move up and down. At this time, the piston block 15 can be driven by the piston rod 18 to move back and forth up and down in the piston cylinder 7. When the piston block 15 moves downward, the air in the sealed space can be sucked into the piston cylinder 7 through the multi-section telescopic tube 13. Conversely, when the piston block 15 moves upward, the air sucked into the piston cylinder 7 can be transported to the exhaust chamber 8 through the exhaust pipe 11, and finally discharged from the exhaust pipe 11 to the outside, thereby achieving the effect of clearing the outside air. In addition, when starting the driving motor 16 to drive the turntable 4 to rotate, the turntable 4 will also drive the piston cylinder 7 to rotate, and then drive the corresponding placement rack to rotate and move through multiple multi-section telescopic tubes 13 to achieve the effect of position adjustment; at the same time, the rotation of the piston cylinder 7 also drives the piston block 15 to rotate, and makes the piston rod 18 rotate together with the rotating sleeve 14, and the piston rod 18 is rotatably connected on the nut plate 20, so there will be no influence between the adjustment of the placement rack position and the vacuum function. Example

[0030] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 9As shown, the microbial culture box also includes a material taking mechanism arranged in the material taking box 5, and is used in conjunction with the placement rack to complete the taking out and placing of the culture dish, and in the process of taking out and placing, they can cooperate with each other to form a sealed state for the storage space of the culture dish, in which the air in the sealed space can be sucked into the exhaust chamber 8 by the exhaust mechanism, thereby effectively isolating the entry of oxygen; the material taking mechanism includes a docking plate 34 that fits and slides on the bottom wall, the top wall and the side wall near the taking and placing port 51 of the material taking box 5, and the interior of the material taking box 5 is provided with a driving member for driving the docking plate 34 to move back and forth, and the docking plate 34 is provided with an arc-shaped concave surface on one side close to the placement rack, and an arc-shaped positioning groove 341 is opened on the arc-shaped concave surface, and the second vertical plate 27 and one side of the placement plate 28 are both provided with an arc-shaped convex surface adapted to the arc-shaped concave surface, so that the entire placement rack can be docked and fitted with the docking plate 34 during the rotation of the turntable 4, and the arc-shaped convex surface on the placement plate 28 is provided with an arc-shaped positioning block 35 used in conjunction with the arc-shaped positioning groove 341. When the entire placement rack rotates and moves with the turntable 4, one side of it can directly fit with some of the docking plate 34, and at the same time, the arc-shaped positioning block 35 can also directly move into the arc-shaped positioning groove 341, so that the placement plate 28 and the docking plate 34 are positioned and connected; then the driving member drives the docking plate 34 to move back and forth, which can drive the entire placement rack to move back and forth, so that it moves from the culture chamber 6 to the material box 5; in order to facilitate movement, the bottom wall of the material box 5 is kept flush with the top of the turntable 4, so that the docking plate 34 can move the placement rack smoothly from the culture chamber 6 to the material box 5.

[0031] In one aspect of the present embodiment, the driving member includes a fixed block 24 fixedly connected to the inner wall of the material picking box 5 on the side away from the loading and unloading port 51, and the same one-way screw 32 is rotatably connected between the fixed block 24 and the inner wall of one side of the material picking box 5. The outer wall of the one-way screw 32 is threadedly sleeved with an L-shaped connecting plate 33 fixedly connected to one side of the docking plate 34, and the outer wall of the material picking box 5 on the side away from the box body 1 is fixedly connected to a second screw motor 26, and the output shaft of the second screw motor 26 rotates through one side of the material picking box 5 and is fixedly connected to one end of the one-way screw 32. Starting the second screw motor 26 to drive the one-way screw 32 to rotate can drive the L-shaped connecting plate 33 to move, thereby driving the docking plate 34 to move back and forth; when the docking plate 34 drives the entire placement rack to move into the culture chamber 6, if there is no need to take out other culture dishes, the placement rack can directly stay on the docking plate 34 to culture the culture solution, because when the placement rack is located in the culture chamber 6, its top and the side away from the second vertical plate 27 are both in an open state. At this time, inert gas is introduced into the culture chamber 6 to complete the cultivation work; when it is necessary to take out or put in other culture dishes, the drive motor 16 is started again to drive the turntable 4 to rotate, and the position of the placement rack can be adjusted. Example

[0032] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 7 As shown, the microbial incubator also includes a blocking mechanism disposed in the feed box 5, which cooperates with the feed mechanism to complete the automatic opening and closing of the feed port 51; the blocking mechanism includes a blocking plate 12 that is sealingly slidably connected to the inner wall of the feed box 5 on the side close to the feed port 51, and the blocking plate 12 is in active contact with the docking plate 34, one side of the blocking plate 12 is fixedly connected to a connecting plate 30, and a same sliding rod 29 is fixedly connected between the fixed block 24 and the inner wall of one side of the feed box 5, the connecting plate 30 is slidably sleeved on the sliding rod 29, and a tension spring 31 is sleeved on the sliding rod 29, and the two ends of the tension spring 31 are fixedly connected to one side of the fixed block 24 and one side of the connecting plate 30, respectively. Figure 6 and Figure 7 As shown, at this time, the docking plate 34 with the entire placement rack is located at the position of the access port 51, and the docking plate 34 is against the sealing plate 12, so that the access port 51 is in an open state, and the tension spring 31 is in a stretched state; when the docking plate 34 with the entire placement rack begins to move into the culture chamber 6, at this time, under the elastic force of the tension spring 31, the sealing plate 12 will be automatically reset through the connecting plate 30, so that the sealing plate 12 automatically closes the access port 51, preventing outside air from flowing into the box body 1, and at the same time preventing a large amount of inert gas in the box body 1 from flowing out of the outside of the box body 1. Example

[0033] This embodiment is a further improvement of the previous embodiment: Figure 1-Figure 9 As shown, a sealing block 36 is slidably connected to the inner side of the first vertical plate 23, and a vent hole 361 is provided on one side of the sealing block 36 for use with one end of the multi-section telescopic tube 13. Two guide rods 37 are symmetrically fixedly connected to one side of the sealing block 36, and one end of the two guide rods 37 slides through one side of the second vertical plate 27 and extends outward. The outer walls of the two guide rods 37 are sleeved with a return spring 38, and the two ends of the return spring 38 are respectively fixedly connected to the end of the guide rod 37 away from the sealing block 36 and the outer side of the second vertical plate 27. Figure 8 As shown in FIG. 1 , when the sealing block 36 is in the initial position, the return spring 38 is in the initial state, and the vent hole 361 and one end of the multi-section telescopic tube 13 are in a misaligned state, that is, at this time, the end of the multi-section telescopic tube 13 connected to the first vertical plate 23 is blocked by the sealing block 36; when the entire placement rack moves from the culture chamber 6 to the material box 5 along with the docking plate 34, as shown in FIG. Figure 6As shown, the sealing block 36 will be pushed and move closer to the position of the second vertical plate 27, and finally hit one side of the second vertical plate 27. At this time, the return spring 38 is in a stretched state as the guide rod 37 moves, and the vent 361 is connected to one end of the multi-section telescopic tube 13 corresponding to the movement of the sealing block 36. Therefore, when the piston cylinder 7 evacuates the sealed space, the multi-section telescopic tube 13 on the placement rack in the culture chamber 6 is blocked by the corresponding sealing block 36, and the multi-section telescopic tube 13 on the placement rack in the material box 5 is in a connected state with the vent 361. Therefore, during the evacuation process, the piston cylinder 7 can only extract the air in the sealed space, and will not extract the inert gas in the culture chamber 6, thereby ensuring that the air in the sealed space is completely extracted, thereby effectively improving the air discharge effect.

[0034] In one aspect of this embodiment, a side of the sealing block 36 away from the second vertical plate 27 is provided with an inclined surface 362, and a side of the material taking box 5 close to the taking and placing port 51 is provided with an extension portion 52 extending into the culture chamber 6, and the extension portion 52 is used in conjunction with the inclined surface 362. Figure 3 and Figure 6 As shown, the material taking box 5 is provided with an extension portion 52 extending into the culture chamber 6. When the docking plate 34 sends the entire placement rack back into the culture chamber 6, the docking plate 34 always maintains a close contact with the extension portion 52. On the one hand, it is convenient to pull the entire placement rack into the material taking box 5 smoothly. On the other hand, through cooperation with the inclined surface 362, when the placement rack is pulled into the material taking box 5, the inclined surface 362 will contact with the extension portion 52, and as the placement rack moves, the sealing block 36 will automatically be pushed in the direction of the second vertical plate 27, so that the sealing block 36 is in contact between the second vertical plate 27 and the inner wall of the material taking box 5, completing the conduction between the vent hole 361 and the multi-section telescopic tube 13. Conversely, when the placement rack is returned to the culture chamber 6, the sealing block 36 can be automatically reset under the elastic force of the reset spring 38, and at this time the sealing block 36 is out of contact with the extension portion 52.
