Description

Technical Field

[0001] This invention belongs to the field of microbial culture technology, and in particular relates to a medical testing microbial culture device. Background Technology

[0002] Microbial culture is a technique that involves inoculating samples into culture flasks or petri dishes to discover and identify bacteria and other culturable microorganisms. Detecting microorganisms in a patient's blood is of great clinical significance for the diagnosis, treatment, and prognosis of infectious diseases. Medical laboratories often need to carry out related work such as immunotherapy and medical care by culturing and observing microorganisms and corresponding bacteria. Therefore, the effective culture of various bacteria and microorganisms is crucial for the laboratory department.

[0003] Currently, in the process of culturing microorganisms in medical testing, it is usually necessary to place the culture flasks or petri dishes containing the microorganisms into a culture device and culture them under specific temperature and humidity conditions. Although existing microbial culture equipment can maintain the specific temperature and humidity environment required for culture, after the culture is completed, the equipment door must be opened to take out the cultured microorganisms and put in the next batch of samples to be cultured. This operation causes the internal temperature and humidity of the equipment to mix with the external temperature and humidity, resulting in significant fluctuations in the internal temperature and humidity environment. Consequently, the equipment needs to spend a long time to readjust the internal temperature and humidity to the specified state during subsequent cultures, thus affecting the culture efficiency of microorganisms. Summary of the Invention

The device comprises: a push rod with a piston fixedly mounted at its bottom end, the piston contacting the inner wall of the cylinder; a second spring slidably sleeved on the push rod; a pressure plate fixedly mounted at the top of the push rod, with multiple limiting rods slidably mounted on the pressure plate, the bottom ends of the multiple limiting rods being fixedly connected to the top of the cylinder; a support block fixedly mounted on the outer wall of the cylinder, with an electromagnet fixedly mounted at its top; an iron sheet fixedly mounted at the bottom of the pressure plate, the iron sheet being positioned above the electromagnet; and a rotating shaft fixedly mounted on one of the screws, with a cam fixedly sleeved on the rotating shaft, the cam being positioned above the pressure plate.

[0015] Compared with related technologies, the medical testing microbial culture equipment provided by this invention has the following beneficial effects: Compared to existing technologies, the medical testing microbial culture equipment provided in this solution, after completing the culture of microorganisms inside the petri dish, uses a moving mechanism to slide the placement plate on the sealing layer until the petri dish in the placement tank is exposed to the outside. During the removal process, the sealing layer on the inner wall of the orifice plate blocks the placement tank and perforations, preventing the external temperature and humidity environment from mixing with the internal temperature and humidity environment of the incubator through the placement tank and perforations. In this way, the temperature and humidity environment inside the incubator will not be significantly affected when the petri dish is removed from the incubator. After the operator removes the petri dish from the placement tank, the next batch of microorganisms to be cultured can be placed into the placement tank. These microorganisms are also loaded onto the petri dish. The culture dish is placed in the placement slot, and then the moving mechanism is activated in reverse to move the placement plate into the incubator from the side until the culture dish in the placement slot is completely inside the incubator. Since the incubator is sealed during the process of placing and removing the culture dish, the internal temperature and humidity environment of the incubator will not be significantly affected. The internal temperature and humidity environment can still be used to cultivate microorganisms, allowing the culture dish to quickly cultivate the microorganisms inside the incubator under the corresponding temperature and humidity environment. This effectively solves the problem that existing microbial culture equipment requires opening and closing the door when taking samples, which causes significant fluctuations in internal temperature and humidity and affects the efficiency of subsequent microbial culture.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] This invention provides a medical testing microbial culture device, such as... Figure 1-12As shown, the medical testing microbial culture equipment includes: a water tank 1, a support base 2 fixedly installed on the top of the water tank 1, an incubator 3 fixedly installed on the top of the support base 2, multiple orifice plates 4 fixedly installed on the incubator 3, a sealing layer fixedly installed on the inner wall of each orifice plate 4, and a placement plate 5 slidably installed on each sealing layer; multiple placement slots 6, each of which is opened on the placement plate 5, and a perforation 47 is opened on the bottom inner wall of each placement slot 6, and a petri dish 7 is placed in each placement slot 6, and the petri dish 7 is used to culture microorganisms for medical testing; multiple heating plates 8, each of which is fixedly installed on one inner wall of the incubator 3, and the heating plates 8 are used to regulate the internal temperature of the incubator 3; and a moving mechanism, which is installed on the incubator 3 and is used to remove the petri dish 7 from the incubator 3.

[0020] In this embodiment, when using this device to culture microorganisms in the petri dish 7, the heating plate 8 and humidification mechanism need to be activated to adjust the temperature and humidity environment inside the incubator 3. Once the temperature and humidity reach the appropriate values, the heating plate 8 and humidification mechanism will stop working, allowing the microorganisms in the petri dish 7 to be cultured under specific temperature and humidity conditions. After the microorganisms have been cultured, the moving mechanism is activated. The moving mechanism will cause the placement plate 5 to slide on the sealing layer of the inner wall of the orifice plate 4, allowing the placement slot 6 on the placement plate 5 to be moved out from the side of the incubator 3 until the petri dish 7 in the placement slot 6 is completely exposed to the outside. During the removal process, the sealing layer of the inner wall of the orifice plate 4 will block the placement slot 6 and the perforation 47 to prevent the external temperature and humidity environment from mixing with the internal temperature and humidity environment of the incubator 3 through the placement slot 6 and the perforation 47. Thus, when the petri dish 7 is removed from the incubator 3, the temperature and humidity environment inside the incubator 3 will not be significantly affected. When the operator places the petri dish 7 outside the incubator 3... After the culture dish 7 is removed from the placement tank 6, the next batch of microorganisms to be cultured can be placed into the placement tank 6. These microorganisms are also loaded into culture dishes 7. Then, the culture dishes 7 are placed into the placement tank 6, and then the moving mechanism is activated in reverse, causing the moving mechanism to drive the placement plate 5 to slide in the reverse direction on the sealing layer. This allows the placement tank 6 on the placement plate 5 to enter the incubator 3 from the side until the culture dishes 7 in the placement tank 6 are completely inside the incubator 3. Since the incubator 3 is in a sealed state during the process of picking up and putting down the culture dishes 7, the internal temperature and humidity environment of the incubator 3 will not be significantly affected. This allows the culture dishes 7 inside the incubator 3 to quickly culture the microorganisms inside under the corresponding temperature and humidity environment. Even if the temperature and humidity environment is slightly off, the heating plate 8 and the humidification mechanism can quickly adjust the internal temperature and humidity environment of the incubator 3 to a specific state, which can reduce the waste of time, improve the culture efficiency of microorganisms, and has a good effect.

[0021] In a further preferred embodiment of the present invention, the moving mechanism includes: a slide rod 9 fixedly installed on the inner wall of the incubator 3, two support plates 10 slidably installed on the slide rod 9, each of the two support plates 10 having threaded holes, and the two support plates 10 being fixedly connected to a plurality of placement plates 5 respectively; two screws 12 rotatably installed on the incubator 3, each of the two screws 12 being adapted to the two threaded holes respectively, and a common smooth rod 11 being fixedly installed at one end of the two screws 12 that is close to each other, the smooth rod 11 being located inside the two threaded holes; a mounting plate 13 fixedly sleeved on the smooth rod 11, with first springs 14 fixedly installed on both sides of the mounting plate 13, the two first springs 14 being located outside the smooth rod 11, and the two sides of the two first springs 14 that are far apart from each other contacting the two support plates 10 respectively; and a servo motor 15 fixedly installed on one side of the incubator 3, the output shaft of the servo motor 15 being fixedly connected to one end of one of the screws 12.

[0022] In this embodiment, the moving mechanism is used to remove the petri dish 7 from the incubator 3. After the microbial culture in the petri dish 7 is completed, the servo motor 15 is activated. The servo motor 15 drives two screws 12 and one guide rod 11 to rotate. At this time, under the push of the two first springs 14, the threaded holes on the two support plates 10 can be quickly threadedly connected to the two screws 12. With the continuous rotation of the two screws 12, the two support plates 10 will slide on the slide rod 9 and move away from each other, causing the two support plates 10 to move multiple placement plates 5 to both sides. The placement plates 5 will slide on the sealing layer, causing the placement grooves 6 on the placement plates 5 to slide. The culture dish 7 can be removed from the side of the incubator 3 until it is completely exposed in the placement tank 6. During the removal process, the sealing layer on the inner wall of the orifice plate 4 will block the placement tank 6 and the perforation 47 to prevent the external temperature and humidity environment from mixing with the internal temperature and humidity environment of the incubator 3 through the placement tank 6 and the perforation 47. In this way, the temperature and humidity environment inside the incubator 3 will not be significantly affected when the culture dish 7 is removed from the incubator 3. Then the operator can take the culture dish 7 out of the placement tank 6, and then place the next batch of microorganisms to be cultured into the placement tank 6. These microorganisms are also loaded in the culture dish 7. Then, the petri dish 7 is placed in the placement slot 6. The servo motor 15 is then started in reverse. The servo motor 15 drives two screws 12 and one guide rod 11 to rotate in the opposite direction. This reverse rotation of the two screws 12 causes two support plates 10 to slide on the slide rod 9 and move closer together. This causes the two support plates 10 to move multiple placement plates 5 into the incubator 3 until the petri dish 7 in the placement slot 6 is completely inside the incubator 3. Since the incubator 3 remains sealed during the placement and removal of the petri dish 7, the internal temperature and humidity environment of the incubator 3 is not significantly affected, ensuring that the petri dish 7 enters the incubator 3 safely. The culture dish 7 inside can quickly cultivate the microorganisms inside under the corresponding temperature and humidity environment. Even if the temperature and humidity environment is slightly off, the heating plate 8 and the humidification mechanism can quickly adjust the internal temperature and humidity environment of the incubator 3 to a specific state, which can reduce the waste of time and improve the cultivation efficiency of microorganisms. When the two support plates 10 approach each other to the corresponding degree, the threaded holes on the two support plates 10 will disengage from the two screws 12 and squeeze the first springs 14 on both sides of the mounting plate 13. In this way, even if the two screws 12 continue to rotate, the two support plates 10 will not continue to move.

[0023] In a further preferred embodiment of the present invention, the medical testing microbial culture equipment further includes a humidification mechanism installed on the water tank 1 and the incubator 3, the humidification mechanism being used to adjust the internal humidity of the incubator 3.

[0024] In this embodiment, the humidity environment inside the incubator 3 can be adjusted by using a humidification mechanism so that humidification can be carried out when the humidity is insufficient.

[0025] In a further preferred embodiment of the present invention, the humidification mechanism includes: a hollow plate 16 fixedly installed on the inner wall of one side of the incubator 3, with a plurality of diversion pipes 17 fixedly installed on the hollow plate 16, and two atomizing nozzles 18 fixedly installed on each of the plurality of diversion pipes 17; a cylinder 19 fixedly installed on one side of the water tank 1, with a plurality of through holes at the top of the cylinder 19 and a water suction pipe 21 fixedly installed at the bottom of the cylinder 19, one end of the water suction pipe 21 extending into the interior of the water tank 1, and a first one-way valve 22 provided on the water suction pipe 21; a drain pipe 23 fixedly installed on the cylinder 19, one end of the drain pipe 23 extending into the interior of the hollow plate 16, and a second one-way valve 24 provided on the drain pipe 23; and a push rod 2 slidably installed on the cylinder 19. 5. A piston 26 is fixedly installed at the bottom end of the push rod 25, and the piston 26 is in contact with the inner wall of the cylinder 19; a second spring 27 is slidably sleeved on the push rod 25; a pressure plate 28 is fixedly installed at the top end of the push rod 25, and a plurality of limiting rods 29 are slidably installed on the pressure plate 28, the bottom ends of the plurality of limiting rods 29 are fixedly connected to the top of the cylinder 19; a support block 30 is fixedly installed on the outer wall of the cylinder 19, and an electromagnet 31 is fixedly installed at the top of the support block 30; an iron sheet 32 ​​is fixedly installed at the bottom of the pressure plate 28, and the iron sheet 32 ​​is located above the electromagnet 31; a rotating shaft 33 is fixedly installed on one of the screws 12, and a cam 34 is fixedly sleeved on the rotating shaft 33, and the cam 34 is located above the pressure plate 28.

[0026] In this embodiment, during the microbial cultivation process, if the humidity inside the incubator 3 is low, the servo motor 15 in the moving mechanism will drive the two screws 12 and one guide rod 11 to rotate in opposite directions. Since the threaded holes on the support plate 10 will not change position due to the rotation of the screws 12 when they are disengaged, the humidification mechanism can be driven by the reverse rotation of the screws 12. During operation, the reverse-rotating screws 12 will drive the rotating shaft 33 to rotate, and the rotating shaft 33 will drive the cam 34 to continuously press the pressure plate 28. The pressure plate 28 is affected by the elastic force of the second spring 27, which enables the pressure plate 28 to continuously move up and down. The pressure plate 28 drives the push rod 25 to slide back and forth on the cylinder 19. The push rod 25 drives the piston 26 to move back and forth on the inner wall of the cylinder 19. Since the top of the cylinder 19 has multiple through holes, the piston 26 can move up and down smoothly on the inner wall of the cylinder 19. When the piston 26 rises, it draws water from the water tank 1 into the cylinder 19 through the water pipe 21. When the piston 26 descends, it expels the water that has entered the cylinder 19. The water source is pumped into the drain pipe 23, and then transported to the hollow plate 16. The water entering the hollow plate 16 flows into multiple branch pipes 17, and finally sprays out from multiple atomizing nozzles 18, thereby humidifying the inside of the incubator 3. Since the water pumping pipe 21 and the drain pipe 23 are respectively equipped with a first one-way valve 22 and a second one-way valve 24, backflow of water in the water pumping pipe 21 and the drain pipe 23 can be prevented, ensuring the stability of the water flow. When the internal humidity of the incubator 3 is adjusted to a suitable range, the electromagnet 31 will be activated. When the pressure plate 28 descends to the corresponding height, the iron plate 32 fixed to the pressure plate 28 will be tightly attracted by the electromagnet 31, causing the pressure plate 28 to stop moving. In this way, even if the cam 34 continues to rotate, the pressure plate 28, push rod 25 and piston 26 will not continue to perform reciprocating lifting and lowering work, which can effectively stop the humidification work. Subsequently, the servo motor 15 stops working. When the internal humidity drops to the corresponding range, the electromagnet 31 will automatically turn off, and the servo motor 15 will drive the two screws 12 and one light rod 11 to rotate in the opposite direction again, thereby resuming the humidification work. Humidification is relatively simple.

[0027] In a further preferred embodiment of the present invention, a support frame 35 is fixedly installed on one side of the support block 30. The support frame 35 is used to support the rotating shaft 33, and the circular hole on the support frame 35 is rotatably connected to the rotating shaft 33.

[0028] In this embodiment, the use of the support frame 35 can provide better support for the rotating shaft 33, making the rotating shaft 33 more stable during rotation and reducing the supporting force of the screw 12 on the rotating shaft 33.

[0029] In a further preferred embodiment of the present invention, a telescopic sleeve 36 is fixedly installed between the cylinder 19 and the pressure plate 28. The telescopic sleeve 36 is located outside the second spring 27 and is used to cover the second spring 27.

[0030] In this embodiment, the use of the telescopic sleeve 36 can reduce the impact of the external environment on the second spring 27, so that the second spring 27 will not be corroded or damaged by the external environment during long-term use.

[0031] In a further preferred embodiment of the present invention, a water filling hopper 56 is fixedly installed on the top of the water tank 1. The water filling hopper 56 is used to add water to the interior of the water tank 1. A cover for covering the water filling hopper 56 is threaded onto the water filling hopper 56.

[0032] In this embodiment, the use of the water filling hopper 56 allows personnel to easily add the required water to the water tank 1. After the water is added, the cover can be screwed onto the water filling hopper 56 by rotation, thereby preventing external impurities from entering the water tank 1 from the water filling hopper 56.

[0033] In a further preferred embodiment of the present invention, the incubator 3 has an opening, a sealing door 57 is provided on the opening, and an observation window 48 is provided on the sealing door 57 for observing microorganisms in the culture dish 7.

[0034] In this embodiment, by using the sealing door 57, when maintenance work needs to be carried out on the inside of the incubator 3, the sealing door 57 can be opened from the opening, and then the maintenance work on the inside of the incubator 3 can be carried out using the appropriate tools. By using the observation window 48, the microorganisms in the culture dish 7 can be observed without opening the sealing door 57, so as to observe the cultivation status of the microorganisms.

[0035] In a further preferred embodiment of the present invention, a temperature and humidity sensor 49 is fixedly installed on the incubator 3, the temperature and humidity sensor 49 is used to detect the temperature and humidity environment inside the incubator 3, and a PLC controller is fixedly installed on one side of the water tank 1.

[0036] In this embodiment, by using the temperature and humidity sensor 49 in conjunction with the PLC controller, the device can automatically turn on and off the heating plate 8 and the humidification mechanism according to the internal temperature and humidity of the incubator 3. When the temperature and humidity drop to the corresponding level, the heating plate 8 and the humidification mechanism will be automatically activated to adjust the temperature and humidity inside the incubator 3, and will be automatically turned off after the temperature and humidity reach the standard.

[0037] In a further preferred embodiment of the present invention, a fixing plate 60 is fixedly installed on each of the plurality of diversion tubes 17, and an illumination lamp 61 is fixedly installed on each of the plurality of fixing plates 60. The plurality of illumination lamps 61 are used to illuminate the culture dish 7.

[0038] In this embodiment, by using the lighting lamp 61, when observing the cultivation of microorganisms, the lighting lamp 61 can be turned on to illuminate the culture dish 7 so that personnel can clearly observe the microorganisms in the culture dish 7.

[0039] To further improve the performance of this device, in addition to the above-mentioned solutions, this solution also includes the following embodiments: In another embodiment of the present invention, the incubator 3 is equipped with a plurality of pushing mechanisms, each of which is used to push out the culture dish 7 in the placement slot 6. The pushing mechanism includes: a strip hole 37 formed on the incubator 3, a support rod 38 fixedly installed on the inner wall of the strip hole 37, and a third spring 39 slidably sleeved on the support rod 38; a slider 40 slidably installed on the support rod 38, the slider 40 being slidably connected to the inner wall of the strip hole 37, and the top of the slider 40 contacting the bottom of the third spring 39; a triangular block 41 fixedly installed on the slider 40; a first horizontal bar 42 fixedly installed on the slider 40, a plurality of second horizontal bars 44 fixedly installed on the first horizontal bar 42, a plurality of vertical bars 45 fixedly installed on the top of each of the plurality of second horizontal bars 44, and a circular plate 46 fixedly installed at the top of each of the plurality of vertical bars 45; and a pressing block 43 fixedly installed on the support plate 10, the pressing block 43 being located on one side of the triangular block 41.

[0040] In this embodiment, after the microbial culture in the petri dish 7 is completed, the servo motor 15 is activated. The servo motor 15 drives two screws 12 and one guide rod 11 to rotate. At this time, under the push of the two first springs 14, the threaded holes on the two support plates 10 can be quickly threadedly connected to the two screws 12. With the continuous rotation of the two screws 12, the two support plates 10 will slide on the slide rod 9 and move away from each other, causing the two support plates 10 to move multiple placement plates 5 to both sides, so that the placement slots 6 on the placement plates 5 can be moved out from the side of the incubator 3 until the petri dish 7 in the placement slots 6 is completely exposed to the outside. During the removal process, the support plates 10 will also drive the squeezing block 43 to approach the triangular block 41. When the squeezing block 43 contacts the triangular block 41, the squeezing block 43 will squeeze the triangular block 41 upward. The triangular block 41 will drive the slider 40 to slide on the support rod 38 and squeeze the third spring 39. The slider 40 will drive the first crossbar 42 to move upward. The first horizontal bar 42 will drive the second horizontal bar 44, the vertical bar 45, and the circular plate 46 to move upward, so that the circular plate 46 passes through the perforation 47 and pushes out the culture dish 7 inside the placement slot 6. This allows the culture dish 7 to be pushed out of the placement slot 6. In this way, after the microbial culture is completed, the staff can quickly take out the culture dish 7 from the placement slot 6. After taking it out, the next batch of microorganisms to be cultured can be loaded into the culture dish 7, and then the culture dish 7 is placed in the placement slot 6. Then, the servo motor 15 is started in reverse to make the circular plate 46 return to its original position, so that the placement slot 6 on the placement plate 5 can enter the incubator 3 from the side until the culture dish 7 in the placement slot 6 is completely entered into the incubator 3. Since the incubator 3 is in a sealed state during the process of taking out and putting in the culture dish 7, the internal temperature and humidity environment of the incubator 3 will not be significantly affected. This allows the culture dish 7 inside the incubator 3 to quickly culture the internal microorganisms in the corresponding temperature and humidity environment, which can effectively improve the culture efficiency.

[0041] In another embodiment of the present invention, a rubber layer 50 for blocking the strip hole 37 is fixedly sleeved on the first crossbar 42, and the edge of the rubber layer 50 is fixedly connected to the outer wall of the incubator 3.

[0042] In this embodiment, the use of the rubber layer 50 can prevent the external environment from mixing with the internal environment of the incubator 3 through the strip hole 37, effectively preventing the internal temperature and humidity environment of the incubator 3 from being affected by the external temperature and humidity environment, and the shielding effect is good.

[0043] In another embodiment of the present invention, a disinfection mechanism is installed on the water tank 1. The disinfection mechanism is used for water source disinfection. The disinfection mechanism includes: a first conduit 58 that is rotatably and sealed on the water tank 1, a plurality of second conduits 59 that are fixedly installed on the first conduit 58, and an ultraviolet germicidal lamp 20 that is fixedly installed on each of the plurality of second conduits 59; a rotating rod 62 that is rotatably installed on the water tank 1; a first bevel gear 51 that is fixedly sleeved on one of the screws 12; a second bevel gear 52 and a third bevel gear 53 that are fixedly sleeved on the rotating rod 62, the second bevel gear 52 meshing with the first bevel gear 51; and a fourth bevel gear 54 that is fixedly sleeved on the first conduit 58, the fourth bevel gear 54 meshing with the third bevel gear 53.

[0044] In this embodiment, the water source in the water tank 1 can be disinfected by the disinfection mechanism to prevent the water source from accumulating a large number of bacteria due to long-term storage. During use, multiple ultraviolet germicidal lamps 20 can be activated to disinfect the water source in the water tank 1. The wiring of the multiple ultraviolet germicidal lamps 20 can be connected by relevant technicians. The connected wiring can be connected to an external power supply through the second conduit 59 and the first conduit 58. When the servo motor 15 drives the screw 12 to rotate, the screw 12 will drive the first bevel gear. When 51 rotates, the first bevel gear 51 drives the rotating rod 62 to rotate on the water tank 1 via the second bevel gear 52. The rotating rod 62 drives the third bevel gear 53 to rotate, and the third bevel gear 53 drives the first conduit 58 to rotate via the fourth bevel gear 54. The first conduit 58 drives the multiple ultraviolet germicidal lamps 20 to rotate via multiple second conduits 59, thereby achieving periodic stirring of the water source and improving the disinfection and sterilization effect of the multiple ultraviolet germicidal lamps 20 on the water source, so that the water source used is kept in a sterile state.

[0045] In another embodiment of the present invention, a cover 55 is fixedly installed on the top inner wall of the water tank 1. The cover 55 is rotatably connected to the first conduit 58 in a sealed manner. The cover 55 is used to cover the third bevel gear 53 and the fourth bevel gear 54.

[0046] In this embodiment, the cover 55 can shield the third bevel gear 53 and the fourth bevel gear 54 to prevent them from being corroded by water.

[0047] In summary, compared with related technologies, after completing the cultivation of microorganisms inside the petri dish 7, this equipment can use a moving mechanism to slide the placement plate 5 on the sealing layer until the petri dish 7 in the placement tank 6 is exposed to the outside. During the removal process, the sealing layer on the inner wall of the orifice plate 4 will block the placement tank 6 and the perforation 47 to prevent the external temperature and humidity environment from mixing with the internal temperature and humidity environment of the incubator 3 through the placement tank 6 and the perforation 47. In this way, when the petri dish 7 is removed from the incubator 3, the temperature and humidity environment inside the incubator 3 will not be significantly affected. After the operator removes the petri dish 7 from the placement tank 6, the next batch of microorganisms to be cultured can be placed into the placement tank 6. These microorganisms are also loaded in petri dishes. In step 7, the culture dish 7 is placed in the placement slot 6, and then the moving mechanism is activated in reverse, causing the moving mechanism to drive the placement plate 5 into the incubator 3 from the side until the culture dish 7 in the placement slot 6 is completely inside the incubator 3. Since the incubator 3 is in a sealed state during the process of taking out and placing the culture dish 7, the internal temperature and humidity environment of the incubator 3 will not be significantly affected. The internal temperature and humidity environment can still be used to cultivate microorganisms, so that the culture dish 7 inside the incubator 3 can quickly cultivate the internal microorganisms in the corresponding temperature and humidity environment. This effectively solves the problem that existing microbial culture equipment requires opening and closing the door when taking out and placing samples, which causes significant fluctuations in internal temperature and humidity and affects the efficiency of subsequent microbial culture.
