Petri dishes are generally divided into two main types: plastic and glass. Glass dishes can be used for plant material, microbial culture, and adherent culture of animal cells. Plastic dishes may be made of polyethylene and are available in both disposable and reusable formats. They are suitable for laboratory inoculation, streaking, and bacterial isolation, and can be used for culturing plant material.

[0003] However, the above technology often has the following defects: in the process of biomedical experiments, culture dishes are often needed. Culture dishes are easily contaminated items. Therefore, when not in use, the culture dishes need to be stored in a fixed device. However, the existing culture dish storage device has a simple structure, and the process of taking or storing is relatively troublesome, which can easily cause damage to the culture dishes, which is not conducive to the storage and use of the culture dishes. In addition, the existing storage device is inconvenient to distinguish and place culture dishes of different models, which is not conducive to the maintenance of the culture dishes.

[0007] In the process of biomedical experiments, culture dishes are often needed. Culture dishes are easily contaminated items. Therefore, culture dishes need to be fixed in a storage device when not in use. However, the existing culture dish storage device has a simple structure, and the process of taking out or storing is relatively troublesome, which can easily cause damage to the culture dishes, which is not conducive to the storage and use of the culture dishes. In addition, the existing storage device is inconvenient to distinguish and place culture dishes of different models, which is not conducive to the maintenance of the culture dishes. When the culture dishes need to be used, the motor is started, and the motor drives the threaded rod to rotate. When the threaded rod rotates, it drives each placement rack to move upward. When the placement rack is extended from the storage rack, the culture dish can be taken out from the placement rack. The provision of the notch portion can more conveniently take out the required culture dish from the side, and different placement racks can be used to store culture dishes of different models, which is convenient for classifying the culture dishes. When the culture dish is finished using, the culture dish is placed in the placement rack, and the motor is started again.

When the culture dish is used up, the culture dish is placed in the placement rack 3, and the motor 2 is started again. At this time, the motor 2 drives the threaded rod 4 to rotate in the opposite direction, and the reversely rotating threaded rod 4 drives the placement rack 3 to move downward until it is put into the storage rack 1, completing the automatic storage of the culture dish, with a high degree of automation, saving time and effort.

The motor rotates and drives the roller 1 8 to move into the placement rack 3. During the movement of the culture dish, it contacts the roller 2 13, and the roller 2 13 rotates immediately, guiding the movement of the culture dish, and the elastic force of the spring piece 1 9 and the spring piece 2 14 causes the movable block 1 7 and the movable block 2 12 to move in the direction of the culture dish, so that the roller 1 8 and the roller 2 13 fix the culture dish in the placement rack 3, so that the culture dish is in a stable state in the storage rack 1, avoiding damage to the culture dish caused by external impact force.

[0034] Among them, a sealing plate 17 is slidably installed on the inner wall of the wiping rack 15, and an elastic rope 18 is fixedly installed on the surface of the sealing plate 17, and the other end of the elastic rope 18 is fixedly connected to the surface of the storage rack 1; when the culture dish needs to be stored, the sealing plate 17 is pulled in the direction away from the storage rack 1, and the elastic rope 18 is stretched when the sealing plate 17 moves. When the sealing plate 17 is away from the storage rack 1, the seal on the placement cavity 5 is unsealed, and the placement rack 3 can be lifted out of the placement cavity 5. When the placement rack 3 is reset after placing the culture dish, the sealing plate 17 is loosened, and the elastic rope 18 drives the sealing plate 17 to reset. After the sealing plate 17 is reset, the placement cavity 5 is sealed to prevent bacteria in the air from entering from the opening of the storage rack 1 and causing bacterial contamination.

[0035] Among them, a limit plate 19 is rotatably installed on the surface of the storage rack 1, and a limit groove 20 is provided on the lower surface of the sealing plate 17.

[0036] Among them, a pair of reagent cartridges 22 are provided on the surface of the wiping rack 15, and disinfectant is provided inside the reagent cartridge 22. An elastic block 23 is provided on the inner wall of the sponge block 16, and a hollow structure is provided inside the elastic block 23. An air pipe 24 is fixedly installed on the surface of the elastic block 23, and the other end of the air pipe 24 is located inside the reagent cartridge 22. A sealing gasket 25 is fixedly installed on the inner wall of the reagent cartridge 22, and a shrinkage hole is provided on the surface of the sealing gasket 25. When the culture dish enters the wiping rack 15 and squeezes the sponge block 16, the deformed sponge block 16 squeezes the elastic block 23. After the elastic block 23 is squeezed, the air inside enters the reagent cartridge 22 along the air pipe 24, and the reagent cartridge The pressure increase in 22 causes the shrinkage hole to open and spray out a little disinfectant. Then the pressure in the reagent cartridge 22 disappears, the shrinkage hole closes immediately, and the internal disinfectant flows into the sponge block 16, so that the sponge block 16 can have a better cleaning effect when wiping. After the sponge block 16 is reset, the elastic block 23 will also recover. When the elastic block 23 recovers, the air in the reagent cartridge 22 is sucked in through the air pipe 24, and negative compression is generated in the reagent cartridge 22. The hole opens again, allowing air to enter the reagent cartridge 22. When the pressure in the reagent cartridge 22 returns to normal, the shrinkage hole closes again, so that whenever the sponge block 16 is squeezed, disinfectant will be sprayed out of the reagent cartridge 22, thereby enhancing the disinfection effect of the sponge block 16.

[0037] Among them, the surface of the wiping frame 15 is provided with a group of positioning rods 26, the surface of the positioning rods 26 is slidably installed with positioning blocks 27, the surface of the positioning blocks 27 is fixedly installed with a group of springs 28, the other end of the springs 28 is fixedly connected to the surface of the wiping frame 15, the surface of the positioning blocks 27 is rotatably installed with a pair of rotating plates 29, the inner wall of the rotating plate 29 is rotatably installed with a cleaning roller 30, the cleaning roller 30 is sticky, and an elastic plate 31 is provided between the rotating plates 29; after wiping the culture dish carefully for many times , press the positioning block 27 downward, the positioning block 27 moves on the surface of the positioning rod 26 and squeezes the spring 28. When the positioning block 27 moves, it drives the cleaning roller 30 on the surface of the rotating plate 29 to pass over the surface of the sponge block 16, adheres the impurities on the surface of the sponge block 16, and cleans the sponge block 16. The elastic plate 31 can make the pair of cleaning rollers 30 always tightly against the surface of the sponge block 16. Then the positioning block 27 is released, and the spring 28 drives the positioning block 27 to reset. When the positioning block 27 is reset, the sponge block 16 is cleaned again.

[0038] Among them, a recovery chamber 33 is opened inside the sealing plate 17, and a recovery groove 32 is opened on the surface of the sealing plate 17. The recovery groove 32 is connected to the recovery chamber 33, and the recovery groove 32 is located directly below the sponge block 16; when the sponge block 16 is squeezed during use, part of the disinfectant water inside will be squeezed out, and the squeezed disinfectant water will fall into the recovery groove 32 and be collected by the recovery chamber 33 to prevent the disinfectant water from spilling on the ground and causing pollution.

[0039] Among them, a magnetic piston plate 34 is slidably installed in the recovery chamber 33, and the magnetic piston plate 34 and the wiping rack 15 attract each other. A group of recovery tubes 35 are provided on the surface of the sealing plate 17, and the other end of the recovery tube 35 is fixedly connected to the surface of the reagent cylinder 22; when the elastic rope 18 drives the sealing plate 17 to reset, the magnetic piston plate 34 and the wiping rack 15 attract each other and remain in the same position. As the sealing plate 17 continues to move, the magnetic piston plate 34 squeezes the recovery chamber 33, so that the disinfectant water in the recovery chamber 33 enters the reagent cylinder 22 along the recovery tube 35, thereby achieving the effect of reuse (the role of the disinfectant water is to enhance the wiping ability of the sponge block 16. The sponge block 16 is used to wipe the disinfectant water on the surface of the culture dish for disinfection. When the sponge block 16 is squeezed, the squeezed disinfectant water is the disinfectant water that does not contact the culture dish, so it can be recycled).

[0040] Example 2: Comparative Example 1, another embodiment of the present invention is that the sponge blocks 16 are arranged in a wavy shape on one side close to each other; the wavy wiping block increases the friction when in contact with the culture dish, thereby improving the effect of wiping and cleaning the culture dish.

[0041] Working principle: When the culture dish needs to be used, start the motor 2, the motor 2 drives the threaded rod 4 to rotate, and the threaded rod 4 drives each placement rack 3 to do an upward movement when rotating. When the placement rack 3 is extended from the storage rack 1, the culture dish can be taken out from the placement rack 3, and the setting of the notch portion can make it more convenient to take out the required culture dish from the side, and different placement racks 3 can be used to store culture dishes of different types, which is convenient for classifying the culture dishes. When the culture dish is finished, the culture dish is placed in the placement rack 3, and the motor 2 is started again. At this time, the motor 2 drives the threaded rod 4 to rotate in the opposite direction. , the reverse-rotating threaded rod 4 drives the placement rack 3 to move downward and until it is stored in the storage rack 1, completing the automatic storage of the culture dish, with a high degree of automation, saving time and labor; when storing the culture dish, first move the corresponding placement rack 3 to a position horizontal to the wiping rack 15, and then insert the culture dish to be stored into the wiping rack 15. After the culture dish enters the wiping rack 15, it contacts the sponge block 16 and moves. During the process, the sponge block 16 wraps around the surface of the culture dish and wipes the culture dish, so that the culture dish is kept clean and pollution-free when stored, avoiding the phenomenon of contamination;

[0042] After the culture dish passes through the wiping rack 15 and is wiped by the sponge block 16, it enters the placement rack 3 and contacts the roller 1 8. The motor is started, and the motor rotates to drive the roller 1 8 to move into the placement rack 3. During the movement of the culture dish, it contacts the roller 2 13, and the roller 2 13 rotates immediately, guiding the movement of the culture dish. The elastic force of the spring piece 1 9 and the spring piece 2 14 makes the movable block 1 7 and the movable block 2 12 move in the direction of the culture dish, so that the roller 1 8 and the roller 2 13 fix the culture dish in the placement rack 3, so that the culture dish is in a stable state in the storage rack 1, avoiding damage to the culture dish caused by external impact force; when the culture dish needs to be stored, the sealing plate 17 is pulled away from the storage rack 1, and the sealing plate 17 moves When the storage rack 1 is in the closed position, the elastic rope 18 is stretched. When the sealing plate 17 is away from the storage rack 1, the seal of the placement chamber 5 is released, and the placement rack 3 can be lifted out of the placement chamber 5. When the placement rack 3 is reset to store the culture dish, the sealing plate 17 is loosened, and the elastic rope 18 drives the sealing plate 17 to reset. After the sealing plate 17 is reset, the placement chamber 5 is sealed to prevent bacteria in the air from entering from the opening of the storage rack 1 and causing bacterial contamination. When the sealing plate 17 is pulled out, the spring plate 21 drives the limiting plate 19 to continuously abut against the lower surface of the sealing plate 17. When the limiting groove 20 on the surface of the sealing plate 17 moves to the upper part of the limiting groove 19, the limiting plate 19 will be inserted into the limiting groove 20 to fix the sealing plate 17, thereby reducing the burden on the staff.

[0043] When the culture dish enters the wiping rack 15 and squeezes the sponge block 16, the deformed sponge block 16 squeezes the elastic block 23. After the elastic block 23 is squeezed, the air inside enters the reagent cartridge 22 along the trachea 24. The pressure in the reagent cartridge 22 increases, causing the shrinkage hole to open and spray out a little disinfectant. Then, the pressure in the reagent cartridge 22 disappears, the shrinkage hole closes immediately, and the internal disinfectant flows into the sponge block 16, so that the sponge block 16 can have a better cleaning effect when wiping. After the sponge block 16 is reset, the elastic block 23 will also recover. When the elastic block 23 recovers, it sucks the air in the reagent cartridge 22 through the trachea 24, and the negative compression hole is opened again in the reagent cartridge 22, allowing air to enter the reagent cartridge 22. When the pressure in the reagent cartridge 22 disappears, the shrinkage hole closes immediately, and the internal disinfectant flows into the sponge block 16. After returning to normal, the shrinkage hole is closed again, so that whenever the sponge block 16 is squeezed, disinfectant water will be sprayed out of the reagent cylinder 22, thereby enhancing the disinfection effect of the sponge block 16; after wiping the culture dish carefully for many times, the positioning block 27 is pressed downward, and the positioning block 27 moves on the surface of the positioning rod 26 and squeezes the spring 28. When the positioning block 27 moves, it drives the cleaning roller 30 on the surface of the rotating plate 29 to pass over the surface of the sponge block 16, adhering impurities on the surface of the sponge block 16 and cleaning the sponge block 16. The elastic plate 31 can make the pair of cleaning rollers 30 always tightly against the surface of the sponge block 16, and then the positioning block 27 is released, and the spring 28 drives the positioning block 27 to reset. When the positioning block 27 is reset, the sponge block 16 is cleaned again;

[0044] When the sponge block 16 is squeezed during use, part of the disinfectant water inside will be squeezed out, and the squeezed disinfectant water will fall into the recovery groove 32 and be collected by the recovery chamber 33 to prevent the disinfectant water from spilling on the ground and causing pollution; when the elastic rope 18 drives the sealing plate 17 to reset, the magnetic piston plate 34 and the wiping frame 15 remain in the mutually attracted position, and as the sealing plate 17 continues to move, the magnetic piston plate 34 squeezes the recovery chamber 33, so that the disinfectant water in the recovery chamber 33 enters the reagent cylinder 22 along the recovery pipe 35, thereby achieving the effect of reuse (the role of the disinfectant water is to improve the wiping ability of the sponge block 16, and the sponge block 16 is used to wipe the disinfectant water on the surface of the culture dish for disinfection. When the sponge block 16 is squeezed, the squeezed disinfectant water is disinfectant water that does not contact the culture dish, so it can be recycled); the wavy wiping block increases the friction when in contact with the culture dish, thereby improving the effect of wiping and cleaning the culture dish.
