[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides an embodiment: Please refer to Figures 1-6 A multifunctional microbial culture device includes a device body 1 and a sealing cover 5. The inner cavity of the device body 1 is provided with a culture dish placement plate 2. The culture dish placement plate 2 is evenly provided with positioning grooves adapted to microbial culture dishes. A support base plate 3 is movably provided at the bottom of the culture dish placement plate 2. In use, the support base plate 3 can support the culture dishes, so that the microbial culture dishes can be stably placed on the support structure formed by the culture dish placement plate 2 and the support base plate 3.

[0023] The support base plate 3 is provided with a groove 19 adapted to the positioning groove. The inner cavity of the groove 19 is provided with a culture dish pushing structure. The culture dish pushing structure includes a pushing plate 17 movably connected to the inner cavity of the groove 19. The pushing plate 17 is connected to the support base plate 3 through an electric telescopic rod 8. When the support base plate 3 rotates, the groove 19 can be aligned with the positioning groove at different positions, so that the pushing plate 17 can contact the bottom of the culture dish at different positions. Under the action of the electric telescopic rod 8, the operation of the electric telescopic rod 8 can change the position of the pushing plate 17. When the pushing plate 17 moves upward, it can drive the culture dish in contact with it to move upward.

[0024] The push plate 17 is detachably connected to the bottom of the microbial culture dish, which improves the reliability of the microbial culture dish during movement. In Example 1, the push plate 17 and the microbial culture dish are detachably connected using a negative pressure connection. Specifically, a vacuum suction cup is integrated on the top of the push plate 17, and a vacuum pump is installed inside the device body 1 to construct an efficient negative pressure connection system. The air inlet of the vacuum pump is connected to the vacuum suction cup through a retractable corrugated vacuum tube, and a sealing gasket is fitted on the top of the vacuum suction cup to enhance airtightness. When the vacuum suction cup is tightly attached to the bottom of the microbial culture dish, the vacuum pump is activated to create a negative pressure environment inside the suction cup, using the pressure difference to achieve a firm adsorption connection between the push plate 17 and the culture dish. This design ensures the stability of the culture dish during the pushing process and also enables convenient disassembly of the culture dish through a non-contact connection method controlled by negative pressure.

[0025] A sealing cover 5 is detachably connected to the top of the device body 1. A turntable 6 is movably connected to the middle of the sealing cover 5. The turntable 6 is connected to the support base plate 3 via a rotating rod 14. The rotating rod 14 is fixedly connected to the turntable 6. The bottom end of the rotating rod 14 is detachably connected to the support base plate 3, and the rotating rod 14 is movably connected to the petri dish placement plate 2. In embodiment 2, a locking block 4 is provided in the middle of the top of the support base plate 3, and a slot adapted to the locking block 4 is provided at the bottom end of the rotating rod 14. Through the setting of the locking block 4 and the slot, the rotating rod 14 and the support base plate 3 can be detachably connected. When the rotating rod 14 is connected to the support base plate 3, when the user drives the rotating rod 14 to rotate, the rotating rod 14 can simultaneously drive the turntable 6 and the support base plate 3 to rotate.

[0026] The turntable 6 is provided with a through hole 13, which is aligned with the groove 19. The inner diameters of the positioning groove, the groove 19 and the through hole 13 are the same. When the through hole 13, the groove 19 and the positioning groove are aligned, the culture dish placed in a positioning groove can be pushed into the through hole 13 under the action of the culture dish pushing structure.

[0027] A rotating ring is movably connected to the top of the turntable 6. The rotating ring has a fixing hole 11. When the fixing hole 11 is misaligned with the through hole 13, the rotating ring can seal the through hole 13, thus sealing the inner cavity of the device and creating a stable microenvironment conducive to the cultivation of microorganisms within the device. A handle 12 is located on one side of the top of the rotating ring. The user can rotate the rotating ring using the handle 12. During rotation, the fixing hole 11 can be aligned with or misaligned with the through hole 13.

[0028] A vent 16 is provided on one side of the bottom of the fixing hole 11. An extension tube 9 adapted to a microbial culture dish is snapped into the fixing hole 11. A piston 15 is movably connected to the inner cavity of the extension tube 9, and a push rod 10 is connected to the top of the piston 15. With the vent 16, when the bottom of the extension tube 9 is at the same height as the bottom of the piston 15, any residual air in the fixing hole 11 can be expelled through the vent 16 during the insertion of the extension tube 9 into the fixing hole 11. As the extension tube 9 continues to move downwards until its bottom is tightly fitted against the top of the turntable 6, the user can adjust the position of the extension tube 9 by rotating the rotating ring to precisely align it with the through hole 13. At this time, the inner cavity of the device remains completely sealed, effectively preventing the entry of outside air and ensuring a stable internal environment. When the culture dish is driven upwards using the culture dish pushing structure, the culture dish will push the piston 15 upwards synchronously until the bottom of the culture dish is at the same height as the top of the turntable 6. Subsequently, the connection between the push plate 17 and the culture dish is released. The user rotates the rotating ring, which, through the extension tube 9, rotates the culture dish until it is misaligned with the push plate 17. At this point, the through hole 13 is completely sealed by the rotating ring. After completing the above operations, the user can remove the extension tube 9. The culture dish is now securely placed in the fixing hole 11, and can then be safely and conveniently removed. The entire process ensures the sealing of the equipment's internal cavity, achieves precise positioning and contamination-free removal of the culture dish, and maintains a stable internal environment.

[0029] A sealing ring 18 is movably fitted on the outer ring of the support base plate 3. The sealing ring 18 is fixedly connected to the equipment body 1. The sealing performance between the support base plate 3 and the equipment body 1 is improved by setting the sealing ring 18. The material of the sealing ring 18 can be selected according to the requirements and is not limited here.

[0030] The outer ring of the top of the sealing cover 5 is provided with a positioning mark, and a fixed pointer 23 is provided on one side of the turntable 6. When the fixed pointer 23 is aligned with the positioning mark, the through hole 13 and the positioning groove are aligned. The user can directly determine whether the through hole 13 and the positioning groove are aligned by using the positioning mark and the fixed pointer 23.

[0031] In Example 3, the positioning grooves on the petri dish placement plate 2 are arranged in concentric circles, forming two circumferential structures, inner and outer. The positioning grooves on both the inner and outer circumferences are evenly distributed in a ring array, achieving the orderly placement of petri dishes of various sizes through the double-circumferential positioning structure. The supporting base plate 3 has two corresponding grooves 19, which are adapted to the positioning grooves on the two circumferential structures. The turntable 6 has two through holes 13 at corresponding positions. The top of the turntable 6 is movably connected to two rotating rings, namely an inner rotating ring 22 and an outer rotating ring 22. All three rotating rings, including the inner and outer rings 7, are provided with fixing holes 11. When there are two types of positioning marks, namely the first mark 20 and the second mark 21, when the fixed pointer 23 is aligned with the first mark 20, a positioning groove on the outer circumference structure is aligned with the groove 19 on the outer ring of the support base plate 3 and the through hole 13 on the outer ring of the turntable 6. When the fixed pointer 23 is aligned with the second mark 21, a positioning groove on the inner circumference is aligned with the groove 19 on the inner ring of the support base plate 3 and the through hole 13 on the inner ring of the turntable 6.

[0032] The sealing cap 5, turntable 6, and rotating ring are all made of transparent material, ensuring visual monitoring of the internal state during operation. The materials used can be customized as needed and are not limited here. Furthermore, in use, the device body 1 integrates essential functional modules for microbial culture, including but not limited to high-precision temperature sensors, intelligent temperature control components, and other basic devices. This provides reliable parameter control and data monitoring for the microbial culture process, meeting the stringent requirements for stability and process controllability in scientific research and industrial applications. The essential functional modules for microbial culture are implemented using conventional technologies in the field, and their specific structure and parameter configuration can be flexibly adjusted according to actual application needs; this application does not limit their specific configuration.

[0033] All electrical components involved in this application are existing technologies. Those skilled in the art can select appropriate models of electrical components according to their needs. No restrictions or elaborations are made here. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies are connected by wires. According to the actual situation, appropriate controllers are selected to meet control requirements. For specific connections and control sequences, please refer to the description below. The electrical connections between each electrical component are completed in the order of their operation. The detailed connection methods are well-known technologies in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0034] In summary: When using this multifunctional microbial culture equipment, the microbial culture dish is placed in the positioning groove, the supporting base plate 3 supports the culture dish, and the sealing cover 5 is used to seal the equipment body 1. Microorganisms are cultured inside the equipment. During the culture process, the user can directly observe the growth of microorganisms in the internal culture dish through the sealing cover 5, the turntable 6 and the rotating ring.

[0035] When the petri dish needs to be removed, the user rotates the turntable 6 by rotating the lever 14 until the fixed pointer 23 is aligned with the positioning mark at the corresponding position. At this time, the groove 19, the through hole 13 and the petri dish to be removed are aligned. The user uses the push rod 10 to move the piston 15 until the bottom of the piston 15 is at the same height as the bottom of the extension tube 9. The user then engages the extension tube 9 with the fixing hole 11. During the engagement process, the gas remaining in the fixing hole 11 is discharged through the vent hole 16 until the bottom of the extension tube 9 contacts the top of the turntable 6. The user then rotates the rotating ring, which moves the extension tube 9 until it is aligned with the through hole 13. At this time, the groove 19, the through hole 13, the petri dish to be removed and the extension tube 9 are aligned.

[0036] The controller of this device controls the operation of the petri dish pushing structure. After the pushing plate 17 is connected to the petri dish, the electric telescopic rod 8 drives the pushing plate 17 to move upward. The pushing plate 17 then moves the petri dish to be removed upward. After the top of the petri dish contacts the bottom of the piston 15, the continued upward movement of the petri dish pushes the piston 15 upward until the bottom of the petri dish is at the same height as the top of the turntable 6. After disconnecting the pushing plate 17 from the petri dish, the user drives the rotating ring to rotate. The rotating ring, through the extension tube 9, drives the petri dish to rotate until the petri dish and the pushing plate 17 are misaligned. At this point, the through hole 13 is completely sealed by the rotating ring. After completing the above operations, the user can remove the extension tube 9. At this point, the petri dish is securely placed in the fixing hole 11, and finally, the petri dish can be safely and conveniently removed. The entire process ensures the sealing of the internal cavity of the device, achieves precise positioning and contamination-free removal of the petri dish, and ensures the stability of the internal environment of the device.
