Description

Technical Field

[0001] The present invention relates to the technical field of biochemical culture, in particular to a biochemical culture box with multiple compartments and a method thereof. Background Art

[0002] As core equipment in modern bioengineering, pharmaceutical R&D, and microbial culture, biochemical incubators' functional stability and ease of operation directly impact the reliability of experimental results. Traditional biochemical incubators, often using a single-chamber structure, suffer from low space utilization and a high risk of environmental cross-contamination when accommodating the needs of culturing multiple batches of differentiated samples. While the multi-chamber biochemical incubators that have emerged in recent years enable parallel experiments through a partitioned design, they still suffer from significant technical deficiencies in the material placement process.

[0003] Existing discharge components generally use manually opened chamber doors or simple slide-type feeding mechanisms. The chamber doors need to be opened frequently during operation, causing drastic fluctuations in the temperature, humidity, and gas environment inside the culture chamber, seriously affecting the stability of the microbial growth environment. Especially in sterile culture scenarios, external contaminants can easily invade through the gaps between chamber openings, causing sample contamination. In addition, each chamber of a multi-chamber incubator lacks an independent sealed discharge system. When material is being discharged into a chamber, the sealing of adjacent chambers is difficult to ensure, posing a risk of cross-contamination. Summary of the Invention

[0004] The object of the present invention is to provide a biochemical incubator with multiple chambers and a method thereof to solve the problems raised in the above background technology.

[0006] Preferably, the isolation plates are provided in groups of no less than four, and the movable bottom plate is slidably mounted on the isolation plates; The sealing cover is rotatably mounted on both sides of the storage platform through a rotating shaft. A spur gear is fixedly sleeved on the outside of the rotating shaft, and the spur gear is connected to the flip assembly.

[0007] Preferably, the flip assembly includes a tooth plate, a movable frame and a driven push bar, and the movable frame is limitedly slidably mounted on the movable bottom plate; One end of the tooth plate is fixedly connected to the movable frame, and the other end of the tooth plate is meshed and connected to the spur gear; The movable frame is provided with no less than three groups of oblique grooves, in which the toggling columns are inserted, and the toggling columns are fixedly connected to the driven push strips.

[0008] Preferably, the flip assembly further comprises a contact rod and a spring, and one end of the driven push bar away from the toggle column is fixedly connected to the contact rod; The contact rod is a T-shaped rod, and one end of the contact rod close to the driven push bar is fixedly connected to the spring.

[0009] Preferably, the rear side walls of the processing chamber and the culture chamber are both provided with mounting grooves for accommodating active components, and the active components include a connecting bar, an active screw and a first handle; The first handle is provided on the outer wall of the rear side of the protective shell and the chassis to facilitate manual adjustment; The connecting bar is limitedly slidably installed in the installation groove and is fixedly connected with an active pushing bar.

[0010] Preferably, the active push bar extends out of the mounting slot and is connected to the contact rod in abutment; The active screw is limitedly rotated and installed in the installation groove and fixedly connected to the first handle. An inner screw hole for accommodating the active screw is opened through the middle of the connecting bar.

[0011] Preferably, each set of protective shells is provided with a set of pushing components, the pushing components including a driving screw and a second handle, the driving screw is limitedly rotatably mounted on the protective shell and fixedly connected to the second handle; The driving screw is coaxially fixedly connected by two short screws with opposite thread directions. A nut seat is sleeved on each short screw, and the two sets of nut seats move horizontally towards each other.

[0012] Preferably, the pushing assembly further comprises a contact plate, a slide rod and a scissor-type hinged rod, one end of the scissor-type hinged rod is rotatably connected to the nut seat, and the other end of the scissor-type hinged rod is rotatably connected to the sliding sleeve; The sliding sleeve is movably sleeved on the sliding rod. Both ends of the sliding rod are fixedly connected with fixed blocks. The fixed blocks are fixedly arranged on the resistance plate.

[0014] A culturing method for a biochemical incubator with multiple compartments comprises the following steps: S1. Open the protective shell of the processing chamber and place the culture on the storage table in the processing chamber; S2. Rotate the first handle on the processing chamber side to drive the active screw, causing the connecting bar to push the active push bar against the contact rod. The flip assembly controls the two sets of sealing covers to flip downward to form an airtight closure. S3. Rotate the second handle of the push assembly to drive the scissor-type hinged rod to extend, pushing the movable bottom plate to move the enclosed storage table horizontally to the culture chamber; S4. Rotate the first handle on the culture chamber side to reverse the active screw, releasing the pressure of the active push bar on the contact rod, causing the sealing cover to flip upward 90° under the action of the spring to expose the storage platform; S5. The culture environment is maintained through the air vents on the side of the culture chamber. When the culture needs to be replaced, the second handle is rotated in the opposite direction to withdraw the current storage table into the processing chamber. Simultaneously, a new storage table pre-installed in the adjacent processing chamber is pushed into the culture chamber. S6. Repeat steps S2-S5 to achieve alternating culture of multiple batches of samples, forming a seamless culture process with a storage platform in a single culture chamber.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This device utilizes evenly spaced isolation panels to create multiple independent culture chambers. This dual-space partitioning of the storage chamber formed by longitudinal partitions creates a multi-level physical isolation system. The dynamic push mechanism of the movable bottom plate and the synchronized opening and closing of the sealing cover work together to form a continuous airtight barrier during material transfer, completely blocking the air flow path between different culture samples. This addresses the industry pain point of seal failure when adjacent chambers of traditional multi-chamber equipment are opened. Particularly in sterile culture scenarios, it effectively prevents the spread of microbial aerosols and the intrusion of external contaminants, significantly improving the culture success rate of highly sensitive biological samples.

[0016] 2. This invention utilizes a mechanically linked design of a flipping and pushing assembly, enabling the sealing cover to achieve a precise 90° flip when the platform enters and exits the chamber, creating a fully enclosed material channel. This dynamic sealing mechanism effectively avoids the sudden temperature and humidity fluctuations associated with manual chamber opening in traditional equipment, maintaining constant environmental parameters within the chamber through physical isolation. The coordinated operation of active components within the processing chamber and the chamber's environmental control system ensures that fluctuations in key parameters such as gas composition and temperature gradients within the chamber during material transfer remain within the tolerance thresholds of bioactive substances, providing an ideal, stable environment for long-term experiments such as cell culture and bacterial propagation.

[0017] 3. The processing chamber and incubation chamber in this invention utilize a split-body design, creating independent operating spaces within a horizontally reversible protective shell. Furthermore, the dual-stage alternating push mechanism, combined with a pre-set sample buffer, supports seamless switching between "incubation" and "preparation" modes, breaking through the limitations of traditional single-station operation.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figures 1 to 11 The present invention provides a technical solution: a biochemical incubator with multiple chambers, comprising a chassis 1, a cavity is provided in the middle of the chassis 1, a plurality of isolation plates 102 are equidistantly provided in the cavity, and the isolation plates 102 are provided in no less than four groups, and a movable bottom plate 3 is slidably mounted on the isolation plates 102, and the plurality of isolation plates 102 divide the cavity into a plurality of culture chambers 101, and the front side walls of the culture chambers 101 are provided with air outlets; processing chambers 103 are provided on both sides of the cavity, and the outer side of the processing chamber 103 is connected to a protective shell 2 through a rotating component, and the protective shell 2 can be horizontally flipped open; a group of storage components is provided in each culture chamber 101, and the storage components include The movable bottom plate 3 and three groups of longitudinal partitions 5 are separated by the three groups of longitudinal partitions 5 into two storage chambers, each of which is provided with a storage table 4 for placing the cultured objects; the movable bottom plate 3 is driven by a pushing component to move left and right, and is used to alternately send the two groups of storage tables 4 into the culture chamber 101; two groups of sealing covers 6 are provided on the outside of the storage tables 4, and the two groups of sealing covers 6 are driven to open or close by a flipping component, so that the storage tables 4 can enter and exit the culture chamber 101 in a sealed manner; the rear side wall of each processing chamber 103 and the rear side wall of each culture chamber 101 are provided with an active component, and the flipping component is powered by the active component.

[0032] Furthermore, the present invention utilizes multiple culture chambers 101 formed by evenly spaced isolation panels 102, combined with the compartmentalization of the movable base 3 and longitudinal partitions 5, to independently culture multiple batches of samples, preventing cross-contamination. The dynamic closure design of the sealing cover 6 and the flip assembly creates an airtight barrier when the storage platform 4 enters and exits the culture chamber 101, ensuring a stable culture environment.

[0033] like Figures 9-11 As shown, the sealing cover 6 is rotatably mounted on both sides of the storage platform 4 via a rotating shaft 7. A spur gear 8 is fixedly sleeved on the outside of the rotating shaft 7, and the spur gear 8 is connected to the flip assembly. The flip assembly includes a toothed plate 9, a movable frame 10, a contact rod 14, a spring 15, and a driven push bar 13. The movable frame 10 is slidingly mounted on the movable bottom plate 3. One end of the toothed plate 9 is fixedly connected to the movable frame 10, and the other end of the toothed plate 9 is meshedly connected to the spur gear 8. The movable frame 10 is provided with no less than three groups of inclined grooves 11, and a toggle column 12 is inserted into the inclined groove 11, and the toggle column 12 is fixedly connected to the driven push bar 13. The end of the driven push bar 13 away from the toggle column 12 is fixedly connected to the contact rod 14; the contact rod 14 is a T-shaped rod, and the end of the contact rod 14 close to the driven push bar 13 is fixedly connected to the spring 15.

[0034] Furthermore, through the design of the tooth plate 9, movable frame 10, inclined groove 11, driven push bar 13, spring 15 and toggle column 12, the linear motion of the linear driving force received by the contact rod 14 can be converted into the synchronous flipping motion of the two groups of sealing covers 6, thereby realizing the mechanical coordination of the opening and closing of the sealing cover 6 and the pushing of the storage table 4, effectively improving the operation accuracy.

[0035] Specifically, when the contact rod 14 squeezes the spring 15 and pushes the driven push bar 13, the toggle column 12 on the driven push bar 13 acts on the inclined slot 11, so that the movable frame 10 is forced to move in the direction away from the spur gear 8, and the toothed plate 9 moving with the movable frame 10 acts on the spur gear 8, so that the rotating shaft 7 coaxially connected to the spur gear 8 drives the sealing cover 6 to flip upward 90°, thereby exposing the storage platform 4; when the external force removes the squeezing force on the contact rod 14, the contact rod 14 drives the driven push bar 13 to pop out quickly under the elastic action of the spring 15, and the toggle column 12 on the driven push bar 13 acts on the inclined slot 11 again, so that the movable frame 10 is forced to move in the direction of the spur gear 8, and the toothed plate 9 moving with the movable frame 10 acts on the spur gear 8 again, so that the rotating shaft 7 coaxially connected to the spur gear 8 drives the sealing cover 6 to flip downward 90°, thereby blocking and sealing the storage platform 4.

[0036] like Figure 7 、 Figure 8 as well as Figure 10-11As shown, the rear side walls of the processing chamber 103 and the culture chamber 101 are each provided with a mounting slot for accommodating an active component. The active component includes a coupling bar 17, an active screw 18, and a first handle 19. The first handle 19 is provided on the rear outer wall of the protective shell 2 and the chassis 1 to facilitate manual adjustment. The coupling bar 17 is slidingly mounted within the mounting slot and is fixedly connected to the active push bar 16. The active push bar 16 extends out of the mounting slot and abuts against the contact rod 14. The active screw 18 is rotationally mounted within the mounting slot and is fixedly connected to the first handle 19. An internal screw hole for accommodating the active screw 18 is provided through the middle of the coupling bar 17.

[0037] Furthermore, an active component formed by a connecting bar 17, an active screw 18 and a first handle 19 is provided on the protective shell 2 and the culture chamber 101, which is used to push the contact rod 14 to perform telescopic movement, and by arranging the first handle 19 on the outside of the processing chamber 103, it is suitable for low-contact operations in a sterile environment.

[0038] like Figure 3-Figure 6 As shown, each set of protective shells 2 is equipped with a push assembly, which includes a drive screw 26, a contact plate 20, a slide bar 22, a scissor-type hinged rod 24, and a second handle 27. The drive screw 26 is mounted on the protective shell 2 for limited rotation and fixedly connected to the second handle 27. The drive screw 26 is coaxially fixedly connected by two short screws with opposite thread directions. Each short screw is sleeved with a nut seat 25, and the two sets of nut seats 25 move horizontally toward each other. One end of the scissor-type hinged rod 24 is rotatably connected to the nut seat 25, and the other end of the scissor-type hinged rod 24 is rotatably connected to the slide bar 22. The slide bar 22 is fixedly connected to a fixed block 21 at both ends. The fixed block 21 is fixedly mounted on the contact plate 20, and the contact plate 20 is contact-connected to the movable base plate 3.

[0039] Furthermore, through the scissor-type hinged rod 24 and the sliding sleeve 23 structure, bidirectional synchronous movement is achieved in the pushing component, ensuring the smooth movement of the storage platform 4.

[0040] Furthermore, by rotating the second handle 27, the driving screw 26 is driven to rotate clockwise. Since the driving screw 26 is coaxially welded by two short screws with opposite thread directions, the two sets of nut seats 25 move toward each other under the rotational action of the internal and external threads. The two sets of nut seats 25 act on the scissor-type hinged rod 24, causing the scissor-type hinged rod 24 to deform and be in an extended state. The other end of the scissor-type hinged rod 24 acts on the sliding sleeve 23, and the sliding sleeve 23 acts on the contact plate 20, causing the contact plate 20 to push the movable base plate 3 to move horizontally.

[0041] like Figure 1-Figure 3As shown, one side of the protective shell 2 is connected to the chassis 1 via a rotating component, and a door-shaped handle is fixedly provided on the other side of the protective shell 2; the rotating component is a hinge. The end of the protective shell 2 near the door-shaped handle is detachably fixed to the chassis 1 via a snap-fit structure.

[0042] Furthermore, through the hinge connection between the protective shell 2 and the chassis 1, the protective shell 2 can be opened 180 degrees according to needs, so that the processing chamber 103 is in an open state, which is convenient for taking and placing materials.

[0043] When the biochemical incubator is in use: first, open the protective shell 2 on the left side to expose the processing chamber 103 on the left side, and place the objects to be cultured one by one on the storage table 4. After placement, immediately rotate the first handle 19 on the rear wall of the processing chamber 103 clockwise three times. The first handle 19 acts on the active screw 18. Under the rotational action of the internal and external threads, the connecting bar 17 is forced to drive the active push bar 16 to extend into the movable bottom plate 3 and push the contact rod 14, so that the contact rod 14 squeezes the spring 15 and pushes the driven push bar 13. The toggle column 12 on the driven push bar 13 acts on the inclined slot 11, so that the movable frame 10 is forced to move toward the direction of the spur gear 8. The toothed plate 9 that moves with the movable frame 10 acts on the spur gear 8, so that the rotating shaft 7 coaxially connected to the spur gear 8 drives the sealing cover 6 to flip downward 90°, thereby blocking and sealing the storage table 4; Then close the left protective shell 2, and turn the second handle 27 on the left protective shell 2 to drive the driving screw 26 to rotate clockwise. Since the driving screw 26 is coaxially welded by two short screws with opposite thread directions, the two sets of nut seats 25 move towards each other under the rotational action of the internal and external threads. The two sets of nut seats 25 act on the scissor-type hinged rod 24, causing the scissor-type hinged rod 24 to be deformed and in an extended state. The other end of the scissor-type hinged rod 24 acts on the sliding sleeve 23, and the sliding sleeve 23 acts on the contact plate 20, causing the contact plate 20 to push the movable bottom plate 3 to move to the right. At this time, the storage platform 4 for the objects to be cultured enters the culture chamber 101, and the storage platform 4 without the objects to be cultured enters the processing chamber 103 on the right and waits for use. At the same time, the culture The first handle 19 on the rear side wall of the culture bin 101 is rotated counterclockwise three times, and the first handle 19 acts on the active screw 18. Under the rotational action of the internal and external threads, the connecting bar 17 is forced to drive the active push bar 16 to extend out of the movable bottom plate 3 and release the squeezing force on the contact rod 14, so that the contact rod 14 pulls the driven push bar 13 outward under the elastic force of the spring 15, and the toggle column 12 on the driven push bar 13 acts on the inclined slot 11 again, so that the movable frame 10 is forced to move in the direction away from the spur gear 8, and the toothed plate 9 that moves with the movable frame 10 acts on the spur gear 8 again, so that the rotating shaft 7 coaxially connected to the spur gear 8 drives the sealing cover 6 to flip upward 90°, thereby exposing the storage table 4 in the culture bin 101, so that the blowing hole can normally act on the cultured objects on the storage table 4.

[0044] During the cultivation process, the cultivation status of each independent cultivation chamber 101 is observed at all times. Once it is found that one group of cultures has undergone qualitative changes or the cultivation is completed, the new cultures are immediately taken out and quickly placed on another group of storage tables 4, and then sent back to the cultivation chamber 101 for cultivation. This arrangement can achieve seamless batch flow. When one group of storage tables 4 needs to be taken out urgently due to sample abnormality, the other group can immediately enter the cultivation process to avoid interruption of the experimental process.

[0045] A culturing method for a biochemical incubator with multiple compartments comprises the following steps: S1. Open the protective shell 2 of the processing chamber 103 and place the culture on the storage table 4 within the processing chamber 103; S2. The first handle 19 on the side of the rotating processing chamber 103 drives the active screw 18, so that the coupling bar 17 pushes the active push bar 16 against the contact rod 14, and the two sets of sealing covers 6 are controlled to flip downward to form an airtight closure through the flip assembly linkage; S3. Rotate the second handle 27 of the push assembly to drive the scissor-type hinged rod 24 to extend, pushing the movable bottom plate 3 to move the enclosed storage platform 4 laterally to the culture chamber 101; S4. The first handle 19 on the side of the rotating culture chamber 101 reversely drives the active screw 18, releasing the active push bar 16 from the extrusion force on the contact rod 14, so that the sealing cover 6 is flipped upward by the spring 15 by 90° to expose the storage station 4; S5. The culture environment is maintained through the vents on the side wall of the culture chamber 101. When the culture needs to be replaced, the second handle 27 is rotated in the opposite direction to withdraw the current placement table 4 into the processing chamber 103. At the same time, the new placement table 4 pre-installed in the adjacent processing chamber 103 is simultaneously pushed into the culture chamber 101. S6. Repeat steps S2-S5 to realize alternating culture of multiple batches of samples, forming a seamless culture process of the storage platform 4 in the single culture chamber 101.

[0046] Furthermore, this culture method ensures that different batches of samples are cultured in independent environments through a multi-chamber isolation design and independent storage chamber division, avoiding cross-contamination between microbial or cell samples.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
