Description

Technical Field

[0001] This invention relates to the field of microbial culture technology, specifically a culture device for regulating the distribution of beneficial microorganisms. Background Technology

[0002] In the field of microbial culture, culture devices typically consist of a sealed chamber and a carrier plate for placing culture dishes. During the culture process, temperature is a key parameter affecting the activity of beneficial bacteria and their metabolites. To ensure a constant temperature, existing devices often equip the sealed chamber with heating elements and fans to achieve heat exchange through forced convection. However, in actual use, due to the fixed positions of the carrier plate and culture dishes, dead air zones can easily form inside the chamber, leading to temperature differences in different areas and making it difficult to meet the requirement of uniform heating of the culture dishes. During or after the culture process, researchers need to open the door or top cover of the sealed chamber to remove the samples. When the temperature inside the chamber differs significantly from the room temperature, opening the top cover will cause a drastic change in the temperature inside the chamber, which will not only affect the activity of the beneficial bacteria being cultured but may also introduce other bacteria, increasing the risk of contamination.

[0003] To address the aforementioned problems, this invention provides a culture device for regulating the distribution of beneficial microorganisms. By circulating the carrier plate within a sealed chamber, airflow is disturbed to improve temperature uniformity, and an independent material handling mechanism is provided at the bottom to ensure stable removal of the culture dish. Summary of the Invention

[0004] The purpose of this invention is to provide a culture device for regulating the distribution of beneficial microorganisms, in order to solve the technical problem in the prior art where temperature changes inside the chamber during sampling by laboratory personnel affect the activity of the beneficial bacteria being cultured, and also introduce contaminants, increasing the risk of contamination.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cultivation device for regulating the distribution of beneficial microorganisms, comprising a machine base and a sealed box. The machine base is equipped with a temperature control system. The sealed box is mounted on the machine base. A pair of mounting bodies are symmetrically arranged on both sides of the sealed box. A movable loading unit is arranged between the pair of mounting bodies. The movable loading unit is located inside the sealed box. An opening is provided at the top of the sealed box, and a main cover is rotatably installed at the opening. The experimenter opens the main cover, places the culture dish containing the beneficial bacteria to be cultured on the carrier plate, and fixes the culture dish using elastic clips. Then, the main cover is closed, isolating the inside of the sealed box from the outside. The experimenter controls the temperature inside the sealed box through the control circuit of the machine base's activation device, and the temperature control system controls the temperature inside the sealed box to make the temperature inside the sealed box suitable for the growth of beneficial bacteria.

[0006] The mobile loading unit includes a pair of pulley mechanisms and several carrier plates. Each pulley mechanism includes an upper guide wheel, a lower guide wheel, and a transmission belt. The transmission belt is installed between the upper guide wheel and the lower guide wheel. Several locking slots are provided on the outer ring of the transmission belt. The number of locking slots is the same as that of the carrier plates. The locking slots are evenly arranged along the transmission belt. A bearing is provided at each locking slot. Pins are provided at both ends of each carrier plate. The pins are connected to the inner ring of the bearing.

[0007] Furthermore, the mounting body comprises an inner liner, a connecting body, and a cover. The cover is installed outside the sealing box. A closed-loop gap of equal width exists between the inner liner and the sealing box, and this closed-loop gap coincides with the contour of the transmission belt. The connecting body connects the cover and the inner liner. The upper and lower guide wheels are rotatably mounted between the cover and the inner liner, with the upper guide wheel positioned above the lower guide wheel. The lower guide wheel is the drive wheel, powered by a servo motor, while the upper guide wheel is the driven wheel. The transmission belt moves between the upper and lower guide wheels. Several locking tabs cycle with the transmission belt, and the carrier plate moves under the drive of the bearings. The movement of the carrier plate disturbs the interior of the sealing box, resulting in a more uniform temperature distribution inside the sealing box.

[0008] Furthermore, each of the carrier plates is U-shaped, with the pin shaft higher than the carrier plate platform. The pin shaft passes through a closed-loop gap and connects to the bearing. The carrier plate is provided with several pairs of elastic retaining strips, each pair of elastic retaining strips fixing the culture dish. The center of gravity of the carrier plate is located below the pin shaft, and the carrier plate and bearing are in a rotatable connection state. The carrier plate relies on its own weight to maintain a horizontal state, preventing it from tipping over and causing the culture dish to fall.

[0009] Furthermore, each pin is fitted with a copper ring near the carrier plate, and several magnets are evenly distributed along the edge of the inner liner plate, with each pair of adjacent magnets having opposite polarities. As the copper ring moves with the carrier plate, the magnets with their alternating opposite poles generate changing magnetic field lines. The copper ring cuts these magnetic field lines during its movement, subsequently inducing a current within the copper ring, which in turn generates an induced magnetic field. This induced magnetic field interacts with the magnetic field of the magnets, damping the rotation of the pin and effectively reducing the swaying of the carrier plate when changing direction, thus stabilizing the culture dish.

[0010] Furthermore, the mobile loading unit includes a servo motor and a linkage shaft. The servo motor is mounted on the outside of a mounting body and is covered with a dust cover. The motor shaft of the servo motor is connected to the shaft of a lower guide wheel, and the linkage shaft connects the two lower guide wheels. When the servo motor drives the lower guide wheel to rotate, it drives the other lower guide wheel to rotate synchronously through the linkage shaft. The pulley mechanisms on both sides of the carrier plate remain synchronized, providing stable support for the carrier plate. After the beneficial bacteria culture is completed, the experimenter opens the main cover and removes the culture dish.

[0011] Furthermore, a material-retrieving unit is installed on the machine platform. This unit is located at the bottom of the sealed chamber, which has a material-retrieving port at the bottom. A material-retrieving cover is installed at the port and is sealed to the sealed chamber. When the temperature difference between the inside of the sealed chamber and room temperature is significant, opening the main cover will cause a drastic temperature change inside the chamber, affecting the cultured beneficial bacteria. The experimenter uses an electric actuator to push a pusher plate to eject the culture dish that has rotated to the bottom carrier plate. The culture dish slides onto a sliding plate, and the experimenter removes the culture dish by opening the material-retrieving cover at the bottom of the sealed chamber.

[0012] Furthermore, the material handling unit includes a pair of electric actuators mounted on the machine base. A positioning frame is connected to the pair of actuators, and a driven head is mounted on the positioning frame. Several push plates are mounted on the driven head, the number of push plates being the same as the number of culture dishes on a carrier plate. When the experimenter needs to remove a culture dish from a carrier plate, the control circuit moves the carrier plate to the bottom, and then the electric actuators drive the positioning frame to move. The positioning frame, through the driven head, drives all the push plates to move. Before the push plates contact the culture dishes, the positioning groove first moves the sliding plate.

[0013] Furthermore, the material handling unit also includes a sliding plate, guide rails are provided on both sides of the sealed box, and sliders are installed at both ends of the sliding plate, with the sliding plate connected to the guide rails through the sliders; A flexible pad is positioned above the sliding plate, and a guide block is positioned above the sliding plate. A cylindrical block is integrally mounted on the guide block. The positioning frame is door-frame shaped, with positioning grooves on both inner sides. The cylindrical block is slidably installed in the positioning grooves. The positioning grooves move the guide block via the cylindrical block. Since the sliding plate is constrained to slide on the guide rail by the slider, the positioning grooves drive the sliding plate to lift upwards, connecting it to the carrier plate. The flexible pad contacts the bottom of the carrier plate, stabilizing and damping the carrier plate. Then, a pusher plate pushes the culture dish from the carrier plate onto the sliding plate. The culture dish slides along the slope of the sliding plate towards the dispensing cover. The experimenter opens the dispensing cover to remove the culture dish. By using a small dispensing cover, the influence of the indoor environment on the internal environment of the sealed chamber is reduced, while also reducing the contact between the experimenter and the carrier plate, providing good isolation and preventing contamination of the sealed chamber by miscellaneous bacteria.

[0014] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting up a mobile loading unit, uses a pulley mechanism to drive the carrier plate to circulate within the sealed chamber, breaking the dead zone of air convection caused by the stationary carrier plate in traditional culture devices. The movement of the carrier plate continuously disturbs the air inside the sealed chamber, promoting the flow of hot air between different areas, effectively eliminating temperature gradients, making the temperature distribution inside the chamber more uniform, providing a stable and consistent temperature environment for the growth of beneficial bacteria, and improving the culture effect.

[0015] By setting up an independent material handling unit at the bottom of the sealed chamber, the culture dishes are pushed to the sliding plate using an electric pusher and a displacement rack, and then removed by a smaller material handling cover, avoiding the need to directly open the main cover. This structure reduces the heat exchange area between the inside of the sealed chamber and the external environment, preventing drastic temperature fluctuations inside the chamber due to excessive temperature differences. At the same time, it effectively blocks the entry of external bacteria, ensuring the stability of the culture process and the purity of the samples. Attached Figure Description

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1-8As shown, Embodiment 1 of the present invention: a culture device for regulating the distribution of beneficial microorganisms includes a machine base 1 and a sealed box 2. The machine base 1 is equipped with a temperature control system. The sealed box 2 is mounted on the machine base 1. A pair of mounting bodies 3 are symmetrically arranged on both sides of the sealed box 2, and a movable loading unit is located between the pair of mounting bodies 3. The movable loading unit is located inside the sealed box 2. An opening is provided at the top of the sealed box 2, and a main cover 4 is rotatably mounted at the opening. The experimenter opens the main cover 4, places a culture dish 15 containing beneficial bacteria to be cultured on a carrier plate 13, and secures the culture dish 15 using elastic clips 14. Then, the main cover 4 is closed, isolating the interior of the sealed box 2 from the outside. The experimenter activates the control circuit of the device through the machine base 1, and the temperature control system controls the temperature inside the sealed box 2 to ensure a suitable temperature for the growth of beneficial bacteria.

[0020] The mobile loading unit includes a pair of pulley mechanisms and several carrier plates 13. Each pulley mechanism includes an upper guide wheel 8, a lower guide wheel 9, and a transmission belt 10. The transmission belt 10 is installed between the upper guide wheel 8 and the lower guide wheel 9. The outer ring of the transmission belt 10 has several locking slots, the same number as the carrier plates 13, and the slots are evenly distributed along the transmission belt 10. Each locking slot is equipped with a bearing 11. Each carrier plate 13 has a pin 16 at both ends, and the pin 16 is connected to the inner ring of the bearing 11. The mobile loading unit includes a servo motor 6 and a linkage shaft 7. The servo motor 6 is mounted on the outside of a mounting body 3, and a dust cover is provided on the outside of the servo motor 6. The motor shaft of the servo motor 6 is connected to the rotating shaft of one lower guide wheel 9, and the linkage shaft 7 is connected between two lower guide wheels 9. The mounting body 3 consists of an inner liner, a connecting body, and a cover. The cover is installed outside the sealing box 2. There is a closed loop gap of equal width between the inner liner and the sealing box 2. The closed loop gap coincides with the outline of the transmission belt 10. The connecting body is connected between the cover and the inner liner. The upper guide wheel 8 and the lower guide wheel 9 are rotatably installed between the cover and the inner liner. The upper guide wheel 8 is located above the lower guide wheel 9.

[0021] The lower guide wheel 9 is the drive wheel, powered by the servo motor 6. The upper guide wheel 8 is the driven wheel. The transmission belt 10 moves between the upper guide wheel 8 and the lower guide wheel 9. Several bayonets cycle with the transmission belt 10. The carrier plate 13 moves under the drive of the bearing 11. The movement of the carrier plate 13 has a disturbing effect on the interior of the sealing box 2, making the temperature distribution inside the sealing box 2 more uniform.

[0022] Each carrier plate 13 is U-shaped, with a pin 16 higher than the platform of the carrier plate 13. The pin 16 passes through a closed-loop gap and connects to the bearing 11. Several pairs of elastic clips 14 are provided on the carrier plate 13, and each pair of elastic clips 14 fixes the culture dish 15. A copper ring 12 is provided near the carrier plate 13 on each pin 16. Several magnets (not shown in the figure) are evenly distributed along the edge of the inner liner plate, with each pair of adjacent magnets having opposite polarities. The center of gravity of the carrier plate 13 is located below the pin 16. The carrier plate 13 and the bearing 11 are in a rotatable connection state. The carrier plate 13 maintains a horizontal state by its own weight to prevent tipping and causing the culture dish 15 to fall. As the copper ring 12 moves with the carrier plate 13, the magnets with their alternating magnetic poles generate changing magnetic field lines. The copper ring 12 cuts these magnetic field lines during its movement, inducing a current within it, which further generates an induced magnetic field. This induced magnetic field interacts with the magnetic field of the magnets, damping the rotation of the pin 16 and effectively reducing the swaying of the carrier plate 13 when changing direction, thus stabilizing the culture dish 15. When the servo motor 6 drives the lower guide wheel 9 to rotate, it drives the other lower guide wheel 9 to rotate synchronously via the linkage shaft 7. The pulley mechanisms on both sides of the carrier plate 13 remain synchronized, providing stable support for the carrier plate 13. After the beneficial bacteria culture is complete, the experimenter opens the main cover 4 and removes the culture dish 15.

[0023] Embodiment 2 of the present invention provides a material handling mechanism that is different from that of Embodiment 1. The difference is that this embodiment is improved on the basis of Embodiment 1 by taking out the culture dish 15 from the smaller material handling cover 5, which reduces the influence of the indoor environment on the internal environment of the sealed box 2, while reducing the contact between the experimental personnel and the carrier plate 13, playing a good isolation role, and also preventing the influence of miscellaneous bacteria on the sealed box 2.

[0024] The specific details are as follows: A material handling unit is installed on the machine base 1, located at the bottom of the sealed box 2. A material handling port is provided at the bottom of the sealed box 2, and a material handling cover 5 is installed at the material handling port, which is sealed to the sealed box 2. The material handling unit includes a pair of electric actuators 17, which are mounted on the machine base 1. A displacement frame 18 is connected to the pair of electric actuators 17, and a driven head 21 is provided on the displacement frame 18. Several push plates 22 are installed on the driven head 21, the number of which is the same as the number of culture dishes 15 on a carrier plate 13. When the internal temperature of the sealed box 2 differs significantly from the room temperature, opening the main cover 4 will cause a drastic change in the internal temperature of the sealed box 2, affecting the cultured beneficial bacteria. The experimenter uses the electric actuators 17 to drive the push plates 22 to push the culture dishes 15 that have rotated to the bottom carrier plate 13. The culture dishes 15 slide onto the sliding plate 19, and the experimenter removes the culture dishes 15 by opening the material handling cover 5 at the bottom of the sealed box 2. When the experimenter needs to remove the culture dish 15 from a certain carrier plate 13, the carrier plate 13 is moved to the bottom through the control circuit, and then the electric push rod 17 drives the positioner 18 to move. The positioner 18 drives all the push plates 22 to move through the driven head 21. Before the push plate 22 touches the culture dish 15, the positioner groove first drives the sliding plate 19 to move.

[0025] The material handling unit also includes a sliding plate 19. Guide rails are provided on both sides of the sealed box 2. Slider blocks are installed at both ends of the sliding plate 19. The sliding plate 19 is connected to the guide rails through the sliders. A flexible pad 20 is provided above the sliding plate 19. A guide block 23 is provided above the sliding plate 19. A cylindrical block is integrally provided on the guide block 23. The displacement frame 18 is in the shape of a door frame. Displacement grooves are opened on both sides of the displacement frame 18. The cylindrical block is slidably installed in the displacement groove. The displacement groove moves the guide block 23 via the cylindrical block. Since the sliding plate 19 is constrained to slide on the guide rail by the slider, the displacement groove drives the sliding plate 19 to lift upwards. The sliding plate 19 connects with the carrier plate 13, and the flexible pad 20 contacts the bottom of the carrier plate 13 to stabilize and dampen the carrier plate 13. Then, the push plate 22 pushes the culture dish 15 from the carrier plate 13 onto the sliding plate 19. The culture dish 15 slides along the slope of the sliding plate 19 towards the material removal cover 5. The experimenter opens the material removal cover 5 to remove the culture dish 15. By opening the small material removal cover 5, the influence of the indoor environment on the internal environment of the sealed box 2 is reduced, the heat exchange area between the inside of the sealed box 2 and the external environment is reduced, and the temperature fluctuation inside the box is prevented from being too large due to excessive temperature difference. At the same time, the contact between the experimenter and the carrier plate 13 is reduced, which plays a good role in isolation and prevents the influence of miscellaneous bacteria on the sealed box 2, thus ensuring the stability of the culture process and the purity of the sample.

[0026] The working principle of this invention is as follows: The experimenter opens the main cover 4, places the culture dish 15 containing beneficial bacteria on the carrier plate 13, and fixes the culture dish 15 using the elastic clips 14. Then, the main cover 4 is closed, isolating the inside of the sealed box 2 from the outside. The experimenter activates the control circuit of the device through the machine 1, and the temperature control system controls the temperature inside the sealed box 2 to make the temperature suitable for the growth of beneficial bacteria. The lower guide wheel 9 is the drive wheel, powered by the servo motor 6, and the upper guide wheel 8 is the driven wheel. The transmission belt 10 moves between the upper guide wheel 8 and the lower guide wheel 9. Several clips cycle with the transmission belt 10. The carrier plate 13 moves under the drive of the bearing 11. The movement of the carrier plate 13 has a disturbing effect on the inside of the sealed box 2, making the temperature distribution inside the sealed box 2 more uniform.

[0027] The center of gravity of the carrier plate 13 is located below the pin 16. The carrier plate 13 is rotatably connected to the bearing 11. The carrier plate 13 maintains a horizontal state by its own weight, preventing it from tipping over and causing the culture dish 15 to fall. As the copper ring 12 moves with the carrier plate 13, the magnets with their oppositely arranged magnetic poles generate changing magnetic field lines. The copper ring 12 cuts the magnetic field lines during its movement, subsequently generating an induced current in the copper ring 12, which further generates an induced magnetic field. The induced magnetic field and the magnetic field of the magnets interact, causing the rotation of the pin 16 to be damped, effectively reducing the swaying of the carrier plate 13 when changing direction, thus stabilizing the culture dish 15. When the servo motor 6 drives the lower guide wheel 9 to rotate, it drives the other lower guide wheel 9 to rotate synchronously through the linkage shaft 7. The pulley mechanisms on both sides of the carrier plate 13 remain synchronized, providing stable support for the carrier plate 13. After the beneficial bacteria culture is completed, the experimenter opens the main cover 4 and removes the culture dish 15.

[0028] When the temperature difference between the inside of the sealed chamber 2 and the room temperature is large, opening the main cover 4 will cause a drastic change in the internal temperature of the sealed chamber 2, which will affect the cultured beneficial bacteria. The experimenter uses the electric push rod 17 to drive the push plate 22 to push the culture dish 15 that has rotated to the bottom carrier plate 13. The culture dish 15 slides onto the sliding plate 19, and the experimenter takes out the culture dish 15 by opening the material removal cover 5 at the bottom of the sealed chamber 2. When the experimenter needs to remove the culture dish 15 from a certain carrier plate 13, the control circuit moves the carrier plate 13 to the bottom, and then the electric push rod 17 drives the displacement frame 18 to move. The displacement frame 18 drives all the push plates 22 to move through the driven head 21. Before the push plate 22 contacts the culture dish 15, the displacement groove drives the sliding plate 19 to move first.

[0029] The displacement groove drives the guide block 23 to move via the cylindrical block. Since the sliding plate 19 is constrained to slide on the guide rail by the slider, the displacement groove drives the sliding plate 19 to lift upward. The sliding plate 19 connects with the carrier plate 13, and the flexible pad 20 contacts the bottom of the carrier plate 13 to stabilize and dampen the carrier plate 13. Then, the push plate 22 pushes the culture dish 15 from the carrier plate 13 onto the sliding plate 19. The culture dish 15 slides along the slope of the sliding plate 19 towards the material removal cover 5. The experimenter opens the material removal cover 5 to remove the culture dish 15. By opening the small material removal cover 5, the influence of the indoor environment on the internal environment of the sealed box 2 is reduced, and the contact between the experimenter and the carrier plate 13 is reduced, which plays a good role in isolation and prevents bacteria from affecting the sealed box 2.

[0030] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
