[0019] The movable plate pushes the sealing plate, so that the sealing plate drives the storage box to move outward in the containing cavity. At this time, the sealing plate of the culture dish storage box needs to be taken out and protrudes from other sealing plates, so as to facilitate taking out the culture dish and quickly observing the microbial culture of the food sample in the culture dish. After observing the microorganism of the food sample in the culture dish, the sealing plate can be quickly pushed to make the storage box drive the culture dish into the containing cavity for re-sealing culture.

[0039] As Figures 1 to 10 shown, a culture device for food detection comprises a culture box body 1 and a controller 2, the controller 2 is fixedly connected to the top of the outer surface of the culture box body 1, and the inside of the culture box body 1 is provided with a culture assembly for partitioned storage of culture;

[0040] It should be noted that the culture box body 1 is composed of a main box body in the middle and two control box bodies distributed at the upper and lower ends of the main box body, the inside of the main box body of the culture box body 1 contains a plurality of heaters, a plurality of refrigerators, a plurality of constant humidity devices and a ventilation system, the above devices are all used for adjusting the environment in the main box body of the culture box body 1, the controller 2 is composed of a main switch, a button, a display screen and a control panel, the switch is used for controlling the on-off of the culture box body 1, the button is used for adjusting the heaters, the refrigerators, the constant humidity devices and the ventilation system in the culture box body 1, and the display screen is used for displaying the temperature and humidity of the culture box body 1.

[0041] The culture assembly comprises a plurality of groups of partition grooves 31 arranged in a linear array and opened in the inner wall of the main box body of the culture box body 1, two partition grooves 31 at the same horizontal height form a group, and a partition plate 32 is fixedly inserted between the two partition grooves 31 of each group, the inside of the main box body of the culture box body 1 is provided with a plurality of groups of frame plates 33 arranged in a linear array, a plurality of frame plates 33 at the same horizontal height form a group, the gap between every two groups of frame plates 33 is the same as the thickness of the partition plate 32, the main box body of the culture box body 1 and the partition plate 32 and the frame plate 33 are combined into a plurality of accommodation cavities arranged in a rectangular array, a plurality of first through holes 34 arranged in a linear array are opened in each frame plate 33, a sealing strip 35 is fixedly connected to the position corresponding to the partition plate 32 and the frame plate 33 on the outer surface of the main box body of the culture box body 1, a plurality of sealing strips 35 are combined into a rectangle in the shape of the accommodation cavity, each frame plate 33 is slidably connected with a movable plate 36 on both sides, a second through hole 37 is opened in each movable plate 36, two first springs 38 are fixedly connected to one end of each movable plate 36 located in the inside of the culture box body 1, one storage box 39 is inserted into each accommodation cavity, a third through hole 310 is opened in each storage box 39 on both sides, a sealing plate 311 is fixedly connected to one end of each storage box 39 located on the outside of the accommodation cavity, and an observation window 312 is fixedly connected to the middle of each sealing plate 311.

[0042] It should be noted that the first through hole 34, the second through hole 37 and the third through hole 310 are in corresponding positions, the bottom of each storage box 39 is hollow, the top of each storage box 39 is open, the outer surface of each sealing plate 311 is provided with a layer of rubber skin, the sealing plates 311 between every two adjacent storage boxes 39 are tightly fitted, the sealing plate 311 is in contact with the sealing strip 35 and the movable plate 36, which will make the first spring 38 in the compressed state of the movable plate 36, the observation window 312 is made of tempered glass, and in addition, the same row of containing cavities share a heater, a refrigerator, a constant humidity device and a ventilation system.

[0043] Specifically, the staff needs to press the switch on the controller 2 first, adjust the temperature and humidity in the same row of containing cavities through the controller 2 button, then configure the culture medium, use the culture dish to store the food sample and the culture medium, and after the food sample to be detected is configured, the staff takes out a row of multiple storage boxes 39 at the same horizontal height from the containing cavity, that is, the staff holds the sealing plate 311 and pulls the sealing plate 311 to pull out the storage box 39 from the containing cavity. In this process, the sealing plate 311 is no longer in contact with the sealing strip 35 and the movable plate 36, and under the elastic reset action of the first spring 38, the movable plate 36 will slide towards the outside of the incubator body 1, and with the sliding of the movable plate 36, the second through hole 37 provided on the movable plate 36 will also move together, at this time the second through hole 37 and the first through hole 34 are misaligned with each other, and the containing cavity of the storage box 39 is in an isolated state. Then the culture dish is placed in the storage box 39, and finally the storage box 39 is pushed back into the containing cavity, at this time the sealing plate 311 will be in contact with the movable plate 36 again during the process of putting the storage box 39 back into the containing cavity, and the movable plate 36 will move on the partition plate 32 towards the side close to the first spring 38, and the movement of the movable plate 36 will compress the first spring 38, at this time the second through hole 37 on the movable plate 36 and the first through hole 34 on the frame plate 33 correspond to each other. In addition, when the sealing plate 311 reaches the innermost side of the containing cavity, the third through hole 310 on the storage box 39 will correspond to the second through hole 37 of the movable plate 36 at this time, and the side of the sealing plate 311 close to the storage box 39 will be in contact with the sealing strip 35. When all the storage boxes 39 at the same horizontal height are put into the containing cavity, the partition plate 32 can make the containing cavities at the same horizontal height in the same space, and the partition plate 32 can layer the storage boxes 39 at different heights, so that the culture dishes of different food samples can be stored in the storage boxes 39 at different horizontal heights, thereby realizing different microbial culture detection of different food samples, meeting the differentiated culture needs of various microorganisms or food samples, without batch operation or the need to equip multiple devices, a single device can realize multiple environment parallel culture, save laboratory space, and reduce equipment procurement and energy consumption cost.

[0044] During the testing of food samples, if it is necessary to observe the culture of microorganisms in the food sample, it can be observed directly through the observation window 312. If it is necessary to remove the petri dish from the storage box 39 for observation, one of the sealing plates 311 can be held and pulled to move the storage box 39 from the inside of the cavity to the outside. At this time, the movable plate 36 loses the pushing force of the sealing plate 311, and then under the elastic reset action of the first spring 38, the movable plate 36 moves away from the first spring 38. At this time, the second through hole 37 on the movable plate 36 will be misaligned with the first through hole 34 on the frame plate 33, so that the first through hole 34 on the frame plate 33 on the side closest to it can be observed. The sealing design ensures that the cavity of the removed container 39 is not interconnected with other cavities. Compared to traditional incubators where samples are removed by opening the door, this design allows only the cavity containing the culture dish to be accessed, while the other cavities remain sealed throughout the process. This prevents the internal environmental parameters from being affected, which is crucial for the microbial culture of food samples. It avoids culture failures or data deviations caused by environmental fluctuations. If a food sample needs to be removed for testing urgently, only the culture dish in the container 39 of one of the cavities needs to be removed, without affecting the continued culture of other food samples. This avoids environmental imbalance caused by opening the door in traditional incubators, thereby reducing the energy consumption generated by readjusting the heater, cooler, humidifier, and ventilation system.

[0045] like Figures 1 to 3 , Figure 6 , Figures 9 to 13 As shown, each sealing plate 311 is provided with a locking assembly for locking the storage box 39 in the receiving cavity. The locking assembly includes two movable grooves 41 opened on both sides of the sealing plate 311. A lifting groove 42 is symmetrically opened on the side of the sealing plate 311 away from the storage box 39. The two lifting grooves 42 are respectively connected to the interior of the two movable grooves 41. A second spring 43 is fixedly connected to the bottom of the two movable grooves 41. A movable block 44 is fixedly connected to the top of the two second springs 43. A locking rod 45 is fixedly connected to the outer surface of the two movable blocks 44. Multiple locking slots 46 arranged in a linear array are fixedly connected to the outer surface of the main box body 1 and the frame plate 33.

[0046] It should be noted that the movable block 44 is composed of a square block and a long plate. The square block of the movable block 44 slides inside the movable groove 41, and the long plate of the movable block 44 slides inside the lifting groove 42. The long plate of the movable block 44 extends out of the lifting groove 42 to the outside of the sealing plate 311, which makes it convenient for the staff to hold the movable block 44 and push it upward. The two locking rods 45 extend out of the movable groove 41 to both sides. The locking buckle 46 is set as a horizontally placed L-shape. The top of the end of the locking buckle 46 away from the incubator body 1 and the frame plate 33 is set as a slope.

[0047] Specifically, when the storage box 39 is placed in the accommodation cavity and moves horizontally, that is, when the sealing plate 311 is in contact with the movable plate 36, the sealing plate 311 will drive the movable block 44 in the movable groove 41 to move synchronously. At this time, the movable block 44 will drive the clamping rod 45 to be in contact with the inclined surface of the clamping groove buckle 46. The clamping rod 45 will move upward under the guidance of the inclined surface of the clamping groove buckle 46. The clamping rod 45 will drive the movable block 44 to move upward in the interior of the movable groove 41. The movable block 44 will stretch the second spring 43. When the clamping rod 45 passes through the inclined surface of the clamping groove buckle 46, the movable block 44 will move downward in the interior of the movable groove 41 under the elastic reset action of the second spring 43. At this time, the movable block 44 will drive the clamping rod 45 to move downward synchronously. Then, the clamping rod 45 will enter the interior of the clamping groove buckle 46. The clamping rod 45 and the clamping groove buckle 46 form a clamping connection. Through the clamping connection between the clamping rod 45 and the clamping groove buckle 46, the sealing plate 311 is locked. The sealing plate 311 always pushes the movable plate 36 and makes the first spring 38 always keep a compressed state. The second through hole 37 on the movable plate 36 always keeps a coinciding relationship with the first through hole 34 on the frame plate 33. At the same time, the sealing plate 311 tightly abuts against the sealing strip 35. Thus, the sealing plate 311, the incubator body 1, the partition plate 32 and the frame plate 33 form a sealed relationship. The culture dishes in the storage box 39 keep a sealed state in the accommodation cavity. That is, the culture dishes are separated from the outside in the accommodation cavity of the incubator body 1. The food samples in the culture dishes can be stably cultured and detected in the accommodation cavity of the incubator body 1.

[0048] In addition, when the culture dishes in the storage box 39 need to be taken out for observation, the clamping connection between the clamping rod 45 and the clamping groove buckle 46 needs to be contacted. The staff can hold the long plate of the movable block 44 and push the long plate of the movable block 44 to move upward in the interior of the lifting groove 42. At the same time, the block of the movable block 44 will move upward in the interior of the movable groove 41. The movable block 44 will drive the clamping rod 45 to move upward in the interior of the clamping groove buckle 46. When the clamping rod 45 is separated from the clamping connection with the clamping groove buckle 46, the movable plate 36 will move outward on the partition plate 32 under the elastic reset action of the first spring 38. At this time, the movable plate 36 will push the sealing plate 311, so that the sealing plate 311 drives the storage box 39 to move outward in the accommodation cavity. The sealing plate 311 of the culture dish storage box 39 needs to be taken out and protrudes from other sealing plates 311. Thus, the culture dishes are convenient to take and the microbial culture of the food samples in the culture dishes is convenient to observe quickly. After observing the microorganisms of the food samples in the culture dishes, the sealing plate 311 can be pushed quickly to make the culture dishes drive the culture dishes to enter the accommodation cavity again for sealed culture. Through the quick operation, the influence of the environment in the accommodation cavity on the culture of the food samples can be reduced.

[0049] The above merely describes preferred embodiments of the present application, and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
