Description

Technical Field

[0001] The utility model relates to the technical field of microbial culture equipment, in particular to an intelligent shaking table. Background Art

[0002] Currently, most shakers on the market have relatively simple functions. Due to the limitations of structural settings and control methods, although most shakers can set different parameter conditions for different culture environments before starting culture, they cannot adjust parameters during the entire culture process. For example, some shakers can adjust temperature parameters before use. After the temperature is set, the shaker is turned on, and the entire culture process thereafter operates at this temperature parameter. Such shakers are difficult to use for microorganisms that require different culture environments at different growth stages.

[0003] Furthermore, the temperature control of shakers currently on the market typically uses air or water bath heating, which results in poor heat transfer, low efficiency, and slow temperature control response. For example, Chinese utility model patent publication number CN205196914U discloses a microbial additive fermentation device with a heating device installed on the side wall of the main tank. This device heats the aqueous medium, transferring heat to the fermentation tank contents to maintain a specific temperature range during the fermentation process.

DETAILED DESCRIPTION

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] like Figure 1 and Figure 2 As shown, the intelligent shaker of the present invention may include an incubator 1, which has a built-in shaking plate 2 and a plurality of independent temperature control modules 3 arranged on the shaking plate 2. Each independent temperature control module 3 is detachably mounted with a heat preservation container 4, which is used to place the culture;

[0029] The independent temperature control module 3 is constructed to act on the bottom of the thermal insulation container 4 by electrically controlling heating or cooling, thereby controlling the ambient temperature inside the thermal insulation container 4 in the form of heat transfer.

[0030] Specifically, the incubator 1 is the main part of the intelligent shaker and can be made of a sealed material with good heat preservation performance to ensure the stability and controllability of the internal environment. The oscillation disk 2 is located inside the incubator 1 and can be driven by a motor to generate horizontal and / or vertical oscillations to promote the growth and mixing of cells or microorganisms in the culture. A plurality of independent temperature control modules 3 are evenly distributed on the oscillation disk 2. Each independent temperature control module 3 heats or cools the heat preservation container 4 by electric control to achieve precise control of its ambient temperature, and can monitor the temperature at the bottom of the heat preservation container 4 in real time through a temperature sensor, and adjust the heating or cooling power according to the deviation between the set value and the actual value. A corresponding heat preservation container 4 is provided on each independent temperature control module 3, and the two are connected by a quick disassembly and assembly structure. The heat preservation container 4 has a certain heat preservation performance, which can reduce the temperature transfer between the inside and outside of the heat preservation container 4 to improve the effect of independent temperature control in the heat preservation container 4.

[0031] Overall, the intelligent shaker of the present invention uses an independent temperature control module 3 to electrically control the temperature of the insulated container 4 by heating or cooling it, thereby controlling the ambient temperature of the culture. This intelligent shaker can replace air or water bath heating methods, improving heat transfer efficiency, accelerating temperature control response, and providing a more suitable microbial culture environment. Furthermore, different independent temperature control modules 3 can be used to achieve different ambient temperature differences for multiple insulated containers 4, allowing for cultivation under different temperature conditions.

[0032] Furthermore, multiple shaking plates 2 can be provided in the incubator 1, and the multiple shaking plates 2 can be detachably mounted at different heights on the support rods to form a multi-layer structure. In this way, more heat preservation containers 4 can be installed in one incubator 1 to cultivate more cultures.

[0033] In one example, Figure 3 As shown, the independent temperature control module 3 includes a mounting block 5 and a semiconductor heating and cooling plate 6. The mounting block 5 is provided with a groove 7 for matching and mounting the thermal insulation container 4, and the semiconductor heating and cooling plate 6 is laid at the bottom of the groove 7.

[0034] Specifically, the mounting block 5 is used to support and mount the thermal insulation container 4. A groove 7 is formed on the mounting block 5. The shape, size, and depth of the groove 7 can be designed to match the shape of the thermal insulation container 4 to ensure that the thermal insulation container 4 can be securely and tightly mounted in the groove 7. The semiconductor heating and cooling plate 6 can be precisely laid at the bottom of the groove 7. The semiconductor heating and cooling plate 6 is an element that works based on the thermoelectric effect and can achieve heating or cooling functions by switching between positive and negative poles as needed, so as to accurately control the ambient temperature in the thermal insulation container 4 according to the set temperature value.

[0035] In this way, the independent temperature control module 3 is designed through the semiconductor heating and cooling plate 6 to achieve precise control of the ambient temperature in the insulation container 4. At the same time, through the reasonable groove 7 design and the installation method of the insulation container 4, the heat transfer efficiency and stability are ensured.

[0036] In one example, Figure 2 and Figure 3 As shown, the heat-insulating container 4 is embedded in the groove 7, and the center of the groove 7 and the bottom center of the heat-insulating container 4 are provided with magnetic parts 8 that are magnetically attracted to each other.

[0037] Specifically, a magnetic member 8 is mounted at the center of groove 7, and a corresponding magnetic member 8 is also positioned at the center of the bottom of thermally insulated container 4 to mate with the magnetic member 8 within groove 7. The polarity or magnetic attraction of the two magnetic members 8 should be precisely designed and adjusted to ensure that thermally insulated container 4 is securely attached to groove 7, preventing it from falling or shaking even during vibration or movement, while also not being so tight as to be difficult to remove. Magnetic member 8 can be a magnet or a ferromagnetic material that is attracted to a magnet.

[0038] In this way, the embedded installation structure between the thermal insulation container 4 and the independent temperature control module 3 achieves a fast, stable and safe connection by using the magnetic member 8. This installation method not only facilitates the user to install and remove the thermal insulation container 4, but also improves the heat transfer efficiency.

[0039] In one example, the heat-insulating container 4 is a cylindrical structure, the groove 7 is a circular groove, and the radial dimension of the groove 7 matches the radial dimension of the heat-insulating container 4 .

[0040] Specifically, the thermal insulation container 4 is designed as a cylindrical structure, and the groove 7 is designed as a circular groove. Its shape and size match the cylindrical structure of the thermal insulation container 4. That is, the diameter of the groove 7 can be slightly larger than the outer diameter of the thermal insulation container 4 to ensure that the thermal insulation container 4 can be easily inserted into the groove 7, facilitating installation and removal operations while maintaining stability. The bottom of the groove 7 has a flat area for mounting the semiconductor heating and cooling plate 6. The bottom of the thermal insulation container 4 is flat to facilitate close contact and fit with the semiconductor heating and cooling plate 6 on the bottom of the groove 7, thereby improving heat transfer efficiency.

[0041] In one example, Figure 3 and Figure 4 As shown, the thermal insulation container 4 has a top opening, a thermal insulation layer 17 is sandwiched between its side walls, and its bottom is made of heat-conducting material.

[0042] Specifically, the thermal insulation container 4 has an open top structure, which makes it easy for users to put in or take out the culture, and also makes it easy for the stirring module 9 to extend into the thermal insulation container 4 for stirring. The thermal insulation container 4 is provided with an insulation layer 17 between the inner lining and the outer wall of its side wall to improve its thermal insulation performance. The insulation layer 17 can be made of thermal insulation materials such as foam plastics, glass fiber, aerogel, etc., which have good thermal insulation performance and can effectively reduce heat transfer. It should be noted that Figure 3 and Figure 4 This is a dissected sidewall illustration to highlight the insulation layer 17. The bottom of the insulation container 4 is made of a thermally conductive material to facilitate heat transfer with the semiconductor heating and cooling fins 6 in the independent temperature control module 3. The thermally conductive material can be a metal (such as stainless steel, aluminum, etc.) or a composite material with high thermal conductivity.

[0043] This design allows the independent temperature control module 3 to conduct heat upward to the insulation container 4 to ensure the temperature environment inside the insulation container 4, while not hindering the stirring operation of the stirring module 9 and the connection with the incubator 1 to share the oxygen concentration environment.

[0044] In one example, Figure 4 As shown, the intelligent shaker also includes a plurality of stirring modules 9 corresponding one to one with the plurality of insulation containers 4. Each stirring module 9 is installed on one side of the insulation container 4, and the stirring module 9 is constructed to extend into the insulation container 4 and be used to stir the culture.

[0045] Specifically, each thermal insulation container 4 is equipped with a corresponding stirring module 9. Each stirring module 9 is installed on one side of the corresponding thermal insulation container 4 so that it can be smoothly inserted into the thermal insulation container 4 to stir the culture. This design of the stirring module 9 can further improve the mixing uniformity of the culture, thereby improving the efficiency and accuracy of the experiment.

[0046] It should be noted that the stirring amplitude of the stirring module 9 is set according to specific needs, but it is necessary to ensure that the culture does not spill out of the insulation container 4 during the stirring process, and the insulation container 4 should also be set at an appropriate height to prevent the culture from spilling out. It should also be noted that Figure 1 Only the stirring module 9 corresponding to one of the heat-insulating containers 4 is shown, and the other stirring modules 9 are not shown.

[0047] In one example, Figure 4 As shown, the stirring module 9 includes a bracket 10, a driving member 11 and a stirring rod 12. The bracket 10 is installed on the oscillation plate 2 and is located on one side of the thermal insulation container 4. The driving member 11 is installed on the bracket 10. The stirring rod 12 is connected to the output end of the driving member 11 and can be extended into the thermal insulation container 4.

[0048] Specifically, the bracket 10 is the supporting structure of the stirring module 9, which can fix the driving member 11 and the stirring rod 12 in appropriate positions. The bracket 10 is installed on the oscillation plate 2 of the intelligent shaker and is located on one side of the thermal insulation container 4 to ensure that the stirring rod 12 can accurately extend into the interior of the thermal insulation container 4. The driving member 11 is the power source of the stirring module 9 and can drive the stirring rod 12 to rotate. The driving member 11 is installed on the bracket 10, and the stirring rod 12 is connected to the output end of the driving member 11 and is connected to the driving member 11 through a transmission mechanism. When the driving member 11 is started, the stirring rod 12 will start to rotate and generate shear force and turbulence effects, thereby achieving uniform stirring of the culture.

[0049] Furthermore, the mounting method of the bracket 10 is detachable, so that the user can replace or adjust it according to the experimental requirements. At the same time, the bracket 10 can also be equipped with an adjustment mechanism for adjusting the depth of the stirring rod 12 inserted into the heat-insulating container 4 to adapt to cultures of different volumes and shapes. The driving member 11 can be a motor, an air motor or other types of power devices. One end of the stirring rod 12 extending into the heat-insulating container 4 is provided with a plurality of stirring blades 18 perpendicular to the stirring rod 12, and the plurality of stirring blades 18 are evenly distributed on the circumference of the stirring rod 12 to improve the stirring effect.

[0050] In one example, Figure 1 As shown, the intelligent shaker further includes an oxygen control module 13 connected to the incubator 1 . The oxygen control module 13 is configured to control the oxygen concentration in the incubator 1 according to the required oxygen concentration of the culture environment.

[0051] Specifically, the oxygen control module 13 is used to monitor and adjust the oxygen concentration in the incubator 1 to ensure that the culture environment meets the experimental requirements. The oxygen control module 13 may include an oxygen sensor, an oxygen controller, and an oxygen supply device (not shown in the accompanying drawings), wherein the oxygen sensor can be installed in the incubator 1 to monitor the oxygen concentration in the culture environment in real time, and can feed back the real-time monitored oxygen concentration data to the oxygen controller; the oxygen controller receives data from the oxygen sensor and can adjust the oxygen concentration in the incubator 1 according to a preset oxygen concentration range (i.e., the required oxygen concentration of the culture environment); the choice of the oxygen supply device depends on the experimental requirements and the overall design of the intelligent shaker. Common oxygen supply devices include oxygen cylinders, oxygen generators, etc.

[0052] In this way, the oxygen control module 13 in the intelligent shaker can accurately control the oxygen concentration in the incubator 1 according to the required oxygen concentration of the culture environment, providing a stable and reliable oxygen environment for the culture experiment, thereby improving the accuracy and reliability of the experiment.

[0053] In one example, Figure 1As shown, the incubator 1 includes a cover 14 and a body 15 that are hinged to each other, and the cover 14 and the body 15 are configured to be interlocked to form a closed culture space.

[0054] Specifically, the incubator 1 includes a box body 15 and a box cover 14. The box body 15 is the main part of the incubator 1, and is used to accommodate and install the oscillation plate 2, the heat preservation container 4, etc.; the box cover 14 is used to close the box body 15, and is engaged with the box body 15 to form a closed culture space to prevent external air, microorganisms and other contaminants from entering the incubator 1. The box body 15 and the box cover 14 are connected together by a hinge, so that the box cover 14 can be rotated to open or close relative to the box body 15. The hinge method can be a traditional hinge hinge, or it can be other forms of hinge devices, such as a gas spring hinge, a damping hinge, etc.

[0055] It should be noted that the lid 14 and the housing 15 are sealed by snapping together. The snapping method can be a snap-on, lock-on, or other type of sealing device. The snapping point between the lid 14 and the housing 15 can also be equipped with a silicone sealing ring or a magnetic sealing strip to provide a better sealing effect and reduce gas leakage and contamination in the culture space.

[0056] In one example, Figure 1 As shown, the intelligent shaker further includes a control display 16 provided in the incubator 1 , and the control display 16 is configured to control the independent temperature control module 3 , the oxygen control module 13 and the stirring module 9 to perform adaptive adjustments.

[0057] Specifically, the control display 16 is installed in a more conspicuous position on the intelligent shaker to facilitate user observation and operation, such as being set on the side or above the incubator 1, so that the user can directly observe the status inside the incubator 1 when adjusting the culture parameters. The control display 16 is electrically connected to the independent temperature control module 3, the stirring module 9 and the oxygen control module 13. The interface design of the control display 16 includes a real-time display area for key parameters such as temperature, oxygen concentration, stirring speed, and corresponding adjustment buttons or touch screen operation areas. Users can use these operation areas to precisely adjust the independent temperature control module 3, the oxygen control module 13 and the stirring module 9. It should be noted that the control display 16 also has a built-in automatic control program, which can pre-set key parameters corresponding to different culture stages of the culture, and can automatically adjust to a suitable culture environment during the culture process.

[0058] In order to better understand the above embodiment, the use process of the intelligent rocking bed of the present invention will be further described below with reference to the accompanying drawings.

[0059] Before use, install the required insulation container 4 in the groove 7 of the independent temperature control module 3, and ensure that the magnetic parts 8 between the insulation container 4 and the groove 7 attract each other so that the insulation container 4 is stably placed; place the culture in the insulation container 4, and adjust the position and stirring speed of the stirring module 9 as needed; connect the oxygen control module 13, and set the required oxygen concentration according to the experimental requirements. Then set the required temperature range, oxygen concentration, stirring speed and other parameters through the control display 16; start the smart shaker, the shaking plate 2 starts working, and the independent temperature control module 3, the oxygen control module 13 and the stirring module 9 are automatically adjusted according to the set values. During the experiment, the user can monitor the oxygen concentration in the incubator 1, the temperature in the insulation container 4 and other parameters in real time through the control display 16. If the parameters need to be adjusted, the user can quickly adjust them through the control display 16 to adapt to changes in experimental requirements.

[0060] In this way, the specific application of the smart shaker in the cultivation of bacterial liquid can change the fermentation quality of the bacterial liquid. On the one hand, the smart shaker can set the temperature of the entire shaking process in time periods through the independent temperature control module 3. For example, if the shaking process requires an appropriate 37°C at the beginning, the temperature is initially set to 37°C. According to time requirements, the temperature can be adjusted through the independent temperature control module 3 when different temperatures are required in different time periods. For example, if the bacterial liquid is not removed in time after fermentation is completed, the smart shaker can automatically lower the temperature to 4°C to avoid the problem of excessive bacterial growth time. On the other hand, the smart shaker can control the stirring frequency of the entire bacterial liquid cultivation process through the vibration plate 2 and the stirring module 9. For example, the stirring speed does not need to be very fast at the beginning, and the speed can be set to low according to actual needs. As the fermentation time continues to increase, the speed can be increased according to the set time. The specific increase is automatically adjusted according to the set parameters. On the other hand, fungi need oxygen supply for growth and reproduction. The dissolved oxygen content of the shaker determines the growth rate and quantity of fungi. The intelligent shaker changes the oxygen concentration in the incubator 1 through the oxygen control module 13 to determine the growth amount of fungi. For example, when the growth cycle of fungi exceeds the corresponding time, there will be a lot of fungi. At this time, the intelligent shaker can correspond to the corresponding oxygen usage and automatically adjust according to needs, thereby meeting the intelligent control requirements of the shaker, improving the environment for fungal growth and fermentation, and completing several times the fermentation work of an ordinary shaker within the corresponding time.
