Description

Technical Field

[0001] This utility model relates to the field of microbial culture technology, and more specifically, to a microbial culture shaker. Background Technology

[0002] In the fields of microbial research and related production, strain cultivation is a crucial step. Strain cultivation requires the use of a culture shaker, which is a device that provides mechanical oscillation. It typically consists of a drive system, an oscillation platform, and a control system. It can perform regular oscillation motion according to set parameters such as frequency and amplitude, providing a uniform mixing, stirring, and aeration environment for experimental samples placed on the oscillation platform.

[0003] A search revealed that Chinese Patent CN211665094U discloses a separate shaker for bacterial culture. Addressing the issue that when there are many culture flasks, those in the middle cannot fully contact the constant-temperature medium, and to ensure a consistent culture environment, culture flasks are typically placed only at the edge of the movable plate, resulting in wasted space. Furthermore, the slots on the movable plate are mostly fixed, making maintenance inconvenient and only applicable to one type of culture flask. The proposed solution is as follows: During bacterial culture, the slots are secured to the shaker frame, and the culture flasks are placed within them. A temperature controller maintains a constant temperature within the shaker, and the motor rotates the turntable, causing continuous vibration of the bacterial solution in the culture flasks, promoting bacterial growth.

[0004] While the above-mentioned technical solutions can solve the problem of wasted space and enable continuous vibration of the bacterial solution in the culture bottle, the shaker only has a simple unidirectional oscillation function, which makes it difficult to fully mix the various nutrients in the culture medium. This leads to differences in the nutrients obtained by the bacteria in different areas during the growth process, affecting the consistency of bacterial growth and overall quality. At the same time, the bacteria may settle at the bottom of the container due to gravity, resulting in uneven distribution of the bacteria and affecting growth. The weak oscillation effect is not enough to keep the bacteria in a suspended state, and the bacteria are prone to settling at the bottom of the container, causing uneven distribution of the bacteria, with some areas growing too densely or too sparsely, which seriously affects the growth and metabolism of the bacteria. Utility Model Content

[0005] In order to overcome the problems and defects in the prior art, this utility model provides a microbial culture shaker to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a microbial culture shaker, comprising a shaker base plate, a movable stage slidably connected to the top of the shaker base plate, an oscillation mechanism provided on the top of the movable stage, and a horizontal shaking mechanism provided between the shaker base plate and the movable stage;

[0007] The oscillation mechanism includes a lifting plate, which is set on the top of the moving platform. A sliding hole is opened on the lifting plate, and a fixed rod is slidably connected inside the sliding hole. The bottom of the fixed rod is fixedly connected to the moving platform, and a connecting spring is sleeved on the outside of the fixed rod.

[0008] A motor is installed at the bottom of the lifting plate. A rotating shaft is fixedly connected to the output end of the motor. A rotating disk is fixedly connected to the top of the rotating shaft. A support rod is fixed to the top of the rotating disk. A fixing plate is fixedly connected to the top of the support rod. A fixing hole is opened on the fixing plate. A fixing groove is opened on the rotating disk. A first vibration motor is fixedly installed at the bottom of the lifting plate.

[0009] Preferably, the horizontal swaying mechanism includes a connecting plate, which is fixed to one side of the moving platform, and two second vibration motors are fixedly installed on one side of the connecting plate.

[0010] Preferably, a groove is provided on the top surface of the shaker base plate, and a slider is slidably connected inside the groove.

[0011] Preferably, the top of the slider is fixedly connected to the moving platform, and a fixing spring is fixedly connected to one side of the slider, with the fixing spring fixed to one side of the inner wall of the slide groove.

[0012] Preferably, the top of the connecting spring is fixedly connected to the bottom of the lifting plate, and the bottom of the connecting spring is fixedly connected to the top of the moving platform.

[0013] Preferably, the rotating shaft is rotatably connected to the lifting plate, and the rotating disk is slidably connected to the top surface of the lifting plate.

[0014] Preferably, the number of support rods, fixing holes, and fixing slots are all set to multiple.

[0015] The technical effects and advantages of this utility model are as follows:

[0016] 1. By setting up a horizontal shaking mechanism, the second vibration motor drives the moving stage to reciprocate horizontally in the chute, causing the bacterial culture tubes placed on the moving stage to shake accordingly. This allows the nutrients in the culture medium to be fully mixed and evenly distributed, ensuring that the bacteria can obtain sufficient nutrients throughout the growth process and providing a good nutritional environment for the bacteria. The sliding connection between the slider and the chute, as well as the setting of the fixing spring, play a role in buffering and assisting in resetting during the shaking of the moving stage, making the entire horizontal shaking process more stable and preventing the culture container from tipping over or the equipment from being damaged due to excessive shaking, thus ensuring the safety and stability of the experiment.

[0017] 2. The rotating disc is driven by a motor, which in turn causes the lifting plate to vibrate up and down via support rods and a fixed plate. Simultaneously, the first vibration motor further enhances the vibration effect. This vibration method ensures that the culture medium in the bacterial culture tubes comes into full contact with air, increasing the dissolved oxygen content and meeting the aerobic respiration requirements of the bacteria. It also ensures thorough mixing of the culture medium and bacteria, improving the bacteria's efficiency in utilizing oxygen and nutrients. The strong vibration keeps the bacteria in suspension, preventing sedimentation at the bottom of the container and ensuring uniform growth due to uneven distribution. This guarantees uniform growth of the bacteria throughout the entire culture system, improving the quality and consistency of the culture and providing better bacterial samples for subsequent research and applications.

[0025] As attached Figure 1-5 The microbial culture shaker shown includes a shaker base plate 1, a movable stage 2 slidably connected to the top of the shaker base plate 1, an oscillation mechanism provided on the top of the movable stage 2, and a horizontal swaying mechanism provided between the shaker base plate 1 and the movable stage 2.

[0026] The oscillation mechanism includes a lifting plate 3, which is set on the top of the moving platform 2. A sliding hole 4 is provided on the lifting plate 3, and a fixed rod 5 is slidably connected inside the sliding hole 4. The bottom of the fixed rod 5 is fixedly connected to the moving platform 2, and a connecting spring 6 is sleeved on the outside of the fixed rod 5.

[0027] A motor 7 is installed at the bottom of the lifting plate 3. A rotating shaft 8 is fixedly connected to the output end of the motor 7. A rotating disk 9 is fixedly connected to the top of the rotating shaft 8. A support rod 10 is fixedly connected to the top of the rotating disk 9. A fixing plate 11 is fixedly connected to the top of the support rod 10. A fixing hole 12 is opened on the fixing plate 11. A fixing groove 13 is opened on the rotating disk 9. A first vibration motor 14 is fixedly installed at the bottom of the lifting plate 3.

[0028] As attached Figure 1 , 2 As shown in Figures 3 and 5, the horizontal shaking mechanism includes a connecting plate 15, which is fixed to one side of the moving table 2. Two second vibration motors 16 are fixedly installed on one side of the connecting plate 15. A groove 17 is provided on the top surface of the shaker base plate 1. A slider 18 is slidably connected inside the groove 17. The top of the slider 18 is fixedly connected to the moving table 2. A fixing spring 19 is fixedly connected to one side of the slider 18. The fixing spring 19 is fixed to one side of the inner wall of the groove 17, so that the bacteria can vibrate back and forth in the horizontal direction, thereby improving the shaking effect.

[0029] As attached Figure 1-4 As shown, the top of the connecting spring 6 is fixedly connected to the bottom of the lifting plate 3, and the bottom of the connecting spring 6 is fixedly connected to the top of the moving platform 2 to improve the vibration effect. The rotating shaft 8 is rotatably connected to the lifting plate 3, and the rotating disk 9 is slidably connected to the top surface of the lifting plate 3, so that the rotating disk 9 can rotate to drive the bacteria to rotate.

[0030] As attached Figure 1-4 As shown, the number of support rods 10, fixing holes 12 and fixing grooves 13 are all set to be multiple, which can accommodate multiple bacterial containers at the same time and ensure the stability of the bacterial containers.

[0031] Working principle of this utility model: During use, the test tube containing the bacterial culture medium is inserted into the fixing hole 12 and the fixing groove 13. When the horizontal shaking mechanism is started, the two second vibration motors 16 installed on one side of the connecting plate 15 start to work. The vibration generated by the second vibration motors 16 is transmitted to the connecting plate 15, which in turn drives the moving stage 2. The bottom of the moving stage 2 is slidably connected to the sliding groove 17 opened on the top of the shaker base plate 1 through the slider 18, and a fixing spring 19 is connected to one side of the slider 18. Under the action of the second vibration motors 16, the moving stage 2 reciprocates horizontally along the sliding groove 17. The fixing spring 19 plays the role of buffering and assisting in reset, making the horizontal shaking more stable and allowing the nutrients in the culture medium to be fully mixed and evenly distributed.

[0032] When motor 7 starts, its output shaft 8 begins to rotate, driving the rotating disk 9, which is fixedly connected to it, to rotate synchronously. The support rod 10 fixed on the top of the rotating disk 9 rotates with the rotating disk 9. Due to the positional relationship between the fixing hole 12 on the fixing plate 11 fixed on the top of the support rod 10 and the fixing groove 13 on the rotating disk 9, when the rotating disk 9 rotates, the support rod 10 will drive the fixing plate 11 to rotate, thereby causing the test tubes in the fixing hole 12 and fixing groove 13 to rotate, thus achieving a shaking effect on the bacteria in the test tubes. At the same time, due to the operation of the first vibration motor 14, the first vibration motor... The machine 14 is installed at the bottom of the lifting plate 3, thereby driving the lifting plate 3 to slide up and down on the fixed rod 5. The bottom of the fixed rod 5 is fixed to the moving platform 2. The top of the connecting spring 6 sleeved on the outside is fixed to the bottom of the lifting plate 3, and the bottom is fixed to the top of the moving platform 2. The connecting spring 6 plays the role of buffering and assisting the lifting plate 3 to reset, realizing the up and down oscillation of the lifting plate 3. This allows the culture medium and bacteria in the test tube placed on the lifting plate 3 and located inside the fixed hole 12 and fixed groove 13 to be fully mixed and in contact with oxygen, while avoiding precipitation at the bottom of the container, which would lead to uneven distribution of bacteria and affect growth.

[0033] In conclusion, the above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
