[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] Please see Figure 1-4 This utility model provides a technical solution:

[0023] A pH-adjustable special culture medium includes: a culture medium body 1; a placement plate 2 installed inside the culture medium body 1; a culture box 3 disposed on top of the placement plate 2; and a snap-fit ​​mechanism 4 for quickly installing the culture box 3 onto the placement plate 2, wherein the snap-fit ​​mechanism 4 is disposed on top of the placement plate 2.

[0024] By setting up the culture medium body 1, the placement plate 2, the culture box 3 and the snap-fit ​​mechanism 4, the culture box 3 can be quickly installed and removed from the placement plate 2, which solves the problem of inconvenience in removing bacteria after culture in traditional culture media, improves the convenience of experimental operation, and at the same time, the snap-fit ​​mechanism 4 also ensures structural stability during the culture process.

[0025] Specifically, the snap-fit ​​mechanism 4 includes two sets of limiting plates 41, multiple sets of limiting blocks 42, and multiple sets of limiting grooves 43; the two sets of limiting plates 41 are symmetrically fixedly installed on the top of the placement plate 2, and the multiple sets of limiting blocks 42 are respectively fixedly installed on both sides of the culture box 3, and the two sets of limiting plates 41 are respectively provided with two sets of limiting grooves 43 for the limiting blocks 42 to snap-fit ​​on the opposite side.

[0026] With the setting of two sets of limiting plates 41, multiple sets of limiting blocks 42, and multiple sets of limiting grooves 43, the two sets of limiting plates 41 are symmetrically arranged, and the multiple sets of limiting blocks 42 form a bidirectional limiting structure, so that the culture box 3 remains stable after installation and avoids displacement. Moreover, the disassembly operation is convenient. Simply pull the culture box 3 upward, and the limiting block 42 will disengage from the limiting groove 43, so the culture box 3 can be quickly removed without complicated tools.

[0027] The snap-fit ​​mechanism 4 also includes a groove 44, which has a top opening for the placement plate 2, and the inner wall of the groove 44 is adapted to the outer wall of the culture box 3.

[0028] By setting the groove 44, the culture box 3 can be effectively prevented from shifting during the culture process after it is placed in the groove 44, which further enhances the installation stability of the culture box 3.

[0029] Specifically, it also includes a pH adjustment mechanism 5, which is located on top of the culture medium body 1.

[0030] The pH adjustment mechanism 5 allows for easy adjustment of the pH value within the culture box 3, ensuring the stability of the bacterial culture environment.

[0031] The pH adjustment mechanism 5 includes two sets of storage tanks 51, two sets of micro pumps 52, two sets of extraction pipes 53, and two sets of delivery pipes 54. The two sets of storage tanks 51 are fixedly installed on the top of the culture medium body 1. The water inlet of the two sets of micro pumps 52 is connected to the inside of the two sets of storage tanks 51 through the two sets of extraction pipes 53, and the water inlet of the two sets of micro pumps 52 is connected to the delivery pipes 54. The end of the two sets of delivery pipes 54 away from the micro pumps 52 extends into the inside of the culture medium body 1.

[0032] With the configuration of two sets of storage tanks 51, two sets of micro pumps 52, two sets of extraction pipes 53, and two sets of delivery pipes 54, the two sets of storage tanks 51 are used to store acidic and alkaline conditioning solutions respectively. The two sets of micro pumps 52 can be corrosion-resistant diaphragm pumps. When the micro pumps 52 are started, the solution is drawn from the storage tanks 51 through the extraction pipes 53, and then the acidic or alkaline conditioning solution is injected into the culture box 3 through the delivery pipes 54, thereby achieving pH adjustment.

[0033] Specifically, it also includes a socket 6 and a pH test probe 7. The top of the culture medium body 1 has a socket 6 for the pH test probe 7 to be inserted.

[0034] With the design of the socket 6 and pH test probe 7, the socket 6 facilitates the insertion of the pH test probe 7, allowing for convenient insertion into the culture box 3 for pH value detection. When the detected pH value deviates from the preset range, the controller automatically starts the micro pump 52 to draw adjustment solution from the corresponding storage tank 51 and inject it into the culture space through the delivery tube 54 until the pH value returns to the set value, thus achieving pH adjustment and providing a stable and suitable acid-base environment for bacterial culture. When detection is not required, the pH test probe 7 can be pulled out of the socket 6, and the socket 6 can be sealed with a sealing plug to ensure the airtightness of the culture medium body 1. The controller is electrically connected to both the pH test probe 7 and the micro pump 52, and the connection and control principles are existing technologies, which will not be elaborated here.

[0035] In a further preferred embodiment, an adjustment component 8 is also included to adjust the position of the culture box 3, and the adjustment component 8 is disposed inside the culture medium body 1.

[0036] By adjusting the settings of component 8, the horizontal position of the placement plate 2 inside the culture medium body 1 can be adjusted, so that the culture box 3 installed above the placement plate 2 can be accurately moved to the lower part of the corresponding delivery tube 54, making it convenient to add acidic or alkaline conditioning solution into the culture box 3.

[0037] Specifically, the adjustment assembly 8 includes a threaded rod 81, an adjustment handwheel 82, and two sets of guide rods 83. The threaded rod 81 is rotatably installed inside the culture medium body 1, and one end of the threaded rod 81 passes through the culture medium body 1 and is fixedly installed with the adjustment handwheel 82. Both sets of guide rods 83 are fixedly installed inside the culture medium body 1. The placement plate 2 is threadedly installed on the outside of the threaded rod 81, and the placement plate 2 is slidably disposed on the outside of the two sets of guide rods 83.

[0038] With the screw rod 81, adjusting handwheel 82, and two sets of guide rods 83, rotating the handwheel drives the screw rod 81 to rotate. The symmetrically arranged guide rods 83 serve as limiting guides, allowing the placement plate 2 to slide smoothly under the guidance of the two sets of guide rods 83. This enables easy adjustment of the position of the culture box 3, facilitating the precise addition of acidic or alkaline conditioning solutions into the culture box 3, avoiding deviation in the addition of conditioning solutions, and improving the accuracy and convenience of adding conditioning solutions. At the same time, the position of the culture box 3 can be flexibly adjusted according to the culture requirements, enhancing the flexibility and adaptability of the culture medium body 1.

[0039] Working principle: When using this utility model, first open the sealed door on the culture medium body 1, insert the limiting blocks 42 on both sides of the culture box 3 into the limiting grooves 43 of the limiting plate 41 on the top of the placement plate 2 and press them down. After the limiting blocks 42 are fully inserted into the limiting grooves 43, the bottom plate of the culture box 3 is also embedded in the groove 44, thereby completing the quick installation of the culture box 3 and ensuring the stability of the bacteria in the culture box 3 during the culture process.

[0040] After the culture is completed, simply pull the culture box 3 upwards, and the limiting block 42 will disengage from the limiting groove 43, allowing the culture box 3 to be quickly removed, thus completing the collection of bacterial samples. The entire process is convenient and effectively improves the convenience and efficiency of experimental operations.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
