Description

Technical Field

[0001] The invention relates to the technical field of microorganism cultivation, and in particular to an airflow circulation type microorganism cultivation device. Background Art

[0002] Microorganisms are a large group of organisms including bacteria, viruses, fungi, some small protozoa, microscopic algae, etc. They are small in size, but have a great impact on the evolution of the earth's environment, the formation of mineral resources, changes in the ecological environment, industrial and agricultural production, and human health. Research related to microorganisms now involves many fields such as petroleum, mining, chemical industry, biology, medicine, food, industry and agriculture, and environmental protection. The cultivation of microorganisms in a specific environment is also considered an important technical means of current scientific research.

[0003] For example, Chinese patent CN202411549787.7 discloses an air circulation type microorganism culture device and method. The device cooperates with the overlapping plate, the first hole plate, the clamping assembly and the closed door, so that when the closed door is closed, the culture vessel placed on the overlapping plate can push the clamping assembly to automatically clamp and fix the culture vessel. In this way, the closing of the closed door can be used to automatically clamp and release, and the clamping assembly also clamps and fixes the culture vessel.

[0004] However, the above patent still has the following deficiencies in actual use:

[0005] For example, when the door is opened, since all the culture tubes are unlocked, when the culture personnel takes the target culture tube, their hands may touch the unlocked instruments around it, causing other culture tubes to shift, tilt or even fall over (for example, glass culture tubes are prone to overturning when their center of gravity is high). Secondly, there is a lack of visual or mechanical auxiliary markings when placing the culture tubes, which makes it impossible for the culture personnel to accurately place the culture tubes in the center area of ​​the two opposing clamping parts. In particular, when multiple tubes are densely arranged, the two opposing clamping parts are prone to exerting unilateral impact force on the culture tubes that are not fully aligned when clamping, causing the tube body to fall over. Since microbial culture needs to maintain a sterile environment for a long time, this technical solution has a high degree of instability when the culture personnel open the door to take and place the culture tubes, which affects the experimental efficiency. Summary of the invention

[0006] The purpose of the present invention is to solve the problem of high instability in the process of opening the box door for taking and placing by the culture personnel in the prior art, and to propose an air circulation type microorganism culture device.

[0015] Furthermore, a groove is provided on one side wall where the two sliding rods are close to each other, and a spring is fixedly connected to the inner wall of the groove, and a pushing block is fixedly connected to the other end of the spring. The outer wall of the pushing block slides in contact with the inner wall of the groove, and triangular oblique grooves are equidistantly provided on one side wall where the two pushing blocks are close to each other, and the pushing block forms a telescopic structure through the spring and the groove.

[0019] Compared with the prior art, the above solution has the following beneficial effects:

[0020] 1. When preparing to take the target culture tube, all the culture tubes can be lifted up and unlocked by moving the support base upward. At the same time, through the coordinated use of the stepped positioning support plate, all the culture tubes arranged in front and behind can be arranged in a stepped manner, so that the distance between adjacent culture tubes is increased, which is convenient for the culture personnel to take the target culture tube, reduces the possibility of touching other culture tubes, and reduces the risk of displacement.

[0021] 2. When preparing to place the target culture tube, the positioning hole can be set to facilitate the rapid placement of the target culture tube in the required clamping position. At the same time, during the downward movement, the outer wall of the target culture tube passing through the outside world can be disinfected by setting the disinfection cotton to avoid the outer wall of the culture tube carrying pollutants after being touched by the culture personnel, reduce human wiping errors, and reduce human intervention links. At the same time, during the disinfection process, the disinfection cotton can be continuously squeezed to maintain the fullness of the contact position between the disinfection cotton and the target culture tube, thereby ensuring the disinfection effect and helping to improve the experimental accuracy of the device.

[0022] 3. When preparing to take the target culture tube, since the microorganisms cultured in an aerobic environment need to continuously supply air into the culture tube, the cup cover is a breathable cup cover. Therefore, when all the culture tubes are unlocked, the two closing plates can be simultaneously driven to move and flip to fit and seal the top of the culture tube that has been moved up, avoiding that all the culture tubes are exposed to the external environment, resulting in the culture tubes that have not been taken out being directly invaded by the outside air due to the exposure, which is beneficial to improving the experimental accuracy of the device.

[0034] Example 1, reference Figure 1-Figure 8 , an air circulation type microorganism culture device, comprising an incubator 1 and a culture tube 2, an air circulator 3 is fixedly installed on the top of the incubator 1, and positioning support plates 4 are fixedly connected to the inner wall of the incubator 1 at equal distances, and the horizontal heights of the four positioning support plates 4 increase in steps from the front side to the rear side of the incubator 1, a mounting plate 5 is fitted on the inner wall of the incubator 1, and an electric push rod 6 is fixedly installed on the bottom inner wall of the incubator 1, and an output rod at one end of the electric push rod 6 is fixedly connected to the bottom of the mounting plate 5.

[0035] Furthermore, a lifting clamping component 7 is equidistantly arranged at the bottom of the four positioning support plates 4, and the lifting clamping component 7 includes a support base 701, and the bottom of the support base 701 is fixedly connected to the top of the mounting plate 5, and positioning holes 702 are equidistantly penetrated at the top of the four positioning support plates 4 corresponding to the culture tubes 2, and a connecting rod 703 is hinged on the outer walls on both sides of the support base 701, and a slider 704 is hinged on the other end of the connecting rod 703, and a sliding groove 705 is penetrated at the bottom of the positioning support plate 4 corresponding to the slider 704, and the outer walls on both sides of the slider 704 slide in contact with the inner wall of the sliding groove 705, and a clamping block 706 is fixedly connected to the top of the slider 704.

[0036] In the embodiment, when the device is in use, an air circulator 3 is fixedly installed on the top of the incubator 1, so that the temperature, humidity and gas composition can be accurately controlled by the air circulator 3 to provide an ideal growth environment for microorganisms. Furthermore, the air circulator 3 is a prior art product, and its specific working principle will not be further described here.

[0037] Then, when it is necessary to take out the target culture tube 2 in the device, first open the door of the incubator 1, then start the electric push rod 6, and the output rod at one end of the electric push rod 6 is fixedly connected to the bottom of the mounting plate 5, and the bottom of the support base 701 is fixedly connected to the top of the mounting plate 5, so that the electric push rod 6 and the mounting plate 5 can synchronously drive multiple support bases 701 to move upward, and then four positioning support plates 4 are equidistantly penetrated through the top of the corresponding culture tubes 2 to provide positioning holes 702, and the outer walls on both sides of the support base 701 are hinged with connecting rods 703, and the other end of the connecting rods 703 is connected to the bottom of the mounting plate 5. A slider 704 is hinged, and a slide groove 705 is provided at the bottom of the positioning support plate 4 corresponding to the slider 704, and the outer walls on both sides of the slider 704 slide in contact with the inner walls of the slide groove 705, and a clamping block 706 is fixedly connected to the top of the slider 704. At the same time, a clamping hole 707 is provided on the side wall where the two clamping blocks 706 are close to each other, corresponding to the culture tube 2, so that when the support base 701 moves upward, the culture tube 2 located in the positioning hole 702 can be lifted up synchronously, and at the same time, the two clamping blocks 706 can be synchronously driven away from each other to release the clamping state through the cooperation of the connecting rod 703 and the slider 704.

[0038] When the support base 701 moves up to the top, most of the outer wall of the culture tube 2 is located at the upper part of the positioning hole 702, and the horizontal height of the four positioning support plates 4 rises in a step-like manner from the front to the back of the incubator 1, so that all the culture tubes 2 arranged in the front and back can form a stepped arrangement, so that the distance between adjacent culture tubes 2 is increased, which is convenient for the culture personnel to take the target culture tube 2, reduces the possibility of touching other culture tubes 2, and reduces the risk of displacement. At the same time, the stepped arrangement can facilitate the culture personnel to better see the label attached to the outer wall of the culture tube 2 and quickly select the required target culture tube 2, which is beneficial to improving the experimental efficiency of the device.

[0039] Furthermore, a filling and disinfection component 8 is equidistantly arranged at the bottom of the four positioning support plates 4, and the filling and disinfection component 8 includes a liquid storage tray 801, and one end face of the liquid storage tray 801 facing the positioning support plate 4 is fixedly connected to the bottom of the positioning support plate 4, a through hole 802 is penetrated through the center of one end face of the liquid storage tray 801 facing the positioning support plate 4 corresponding to the positioning hole 702, and a liquid storage cavity 803 is provided inside the liquid storage tray 801, and a disinfection cotton 804 is fitted on the inner wall of the liquid storage cavity 803, and a circulation ring groove 805 is penetrated through the inner wall of the liquid storage tray 801 corresponding to the culture tube 2, the outer walls of both sides of the two sliders 704 are fixedly connected with a connecting rod 806, and the other end of the connecting rod 806 is fixedly connected with a sliding rod 807, and the sliding rod 807 slides toward the outer wall of one side of the positioning support plate 4 in fit with the bottom of the positioning support plate 4.

[0040] In the embodiment, when the target culture tube 2 that has passed through the outside is put back to its original position, the positioning hole 702 is arranged to facilitate the rapid placement of the target culture tube 2 in the required clamping position, and then the multiple support bases 701 are driven downward by the electric push rod 6. At this time, the culture tube 2 will move downward with the action of gravity, and simultaneously drive the two clamping blocks 706 to approach each other to gradually fit and clamp the top outer wall of the culture tube 2.

[0041] During the downward movement of the culture tube 2, the end surface of the liquid storage tray 801 facing the positioning support plate 4 is first fixedly connected to the bottom of the positioning support plate 4, and a through hole 802 is penetrated through the center of the end surface of the liquid storage tray 801 facing the positioning support plate 4 corresponding to the placement positioning hole 702, and a liquid storage cavity 803 is formed inside the liquid storage tray 801, and a disinfection cotton 804 is fitted on the inner wall of the liquid storage cavity 803, and a circulation annular groove 805 is penetrated through the inner wall of the liquid storage tray 801 corresponding to the culture tube 2, so that when the culture tube 2 is placed in the placement positioning hole 702, the culture tube 2 can be placed in the culture tube 2. The bottom outer wall of the tube 2 will fit with the inner wall of the through hole 802. At this time, through the setting of the circulation groove 805, the part of the surface of the disinfection cotton 804 facing the culture tube 2 will be able to fit and contact with the bottom outer wall of the culture tube 2 through the circulation groove 805, so that in the process of the culture tube 2 moving downward, the outer wall of the target culture tube 2 passing through the outside world can be disinfected by the disinfection cotton 804, avoiding the outer wall of the culture tube 2 that may carry contaminants after being touched by the culture personnel, reducing human wiping errors, reducing human intervention links, and at the same time, other culture tubes 2 can be disinfected simultaneously to take preventive measures.

[0042] Then, a connecting rod 806 is fixedly connected to the outer walls on both sides of the two sliders 704, and a sliding rod 807 is fixedly connected to the other end of the connecting rod 806, and the sliding rod 807 slides toward the outer wall of one side of the positioning support plate 4 and fits with the bottom of the positioning support plate 4, so that the sliding position of the slider 704 can be supported and restricted by the clamping block 706 located on the upper surface of the positioning support plate 4 and the sliding rod 807 located on the lower surface of the positioning support plate 4, thereby ensuring sliding stability.

[0043] Then, during the disinfection process, the movement of the slider 704 can synchronously drive the slide bar 807 to move, and at the same time, a groove 808 is opened on one side wall where the two slide bars 807 are close to each other, and the inner wall of the groove 808 is fixedly connected with a spring 809, and the other end of the spring 809 is fixedly connected with a push block 810, and at the same time, the ends of the four push rods 813 that are far away correspond to the triangular inclined groove 811 in an arc shape, and the ends of the four push rods 813 that are close to each other correspond to the disinfection cotton 804 and are fixedly connected with an extrusion arc block 810. 14, and the upper and lower side walls of the extrusion arc block 814 are fitted and slid with the inner wall of the liquid storage chamber 803, so that in the process of moving down and clamping, the pushing rod 813 can be squeezed by the pushing block 810, and under the elastic force of the spring 809, the extrusion arc block 814 can be driven by appropriate elastic force to squeeze the disinfection cotton 804, and the fullness of the contact position between the disinfection cotton 804 and the target culture tube 2 can be maintained by utilizing this squeezing force, thereby ensuring the disinfection effect, which is beneficial to improving the experimental accuracy of the device.

[0044] Furthermore, when unlocking, a disinfection step will be performed in the same manner. At the same time, triangular bevel grooves 811 are equidistantly opened on one side wall where the two pushing blocks 810 are close to each other, and the pushing block 810 forms a telescopic structure with the groove 808 through the spring 809. Therefore, during the entire downward movement, when the extrusion arc block 814 is squeezed by the tip position of the triangular bevel groove 811, the maximum squeezing force is achieved at this time. When the tip of the triangular bevel groove 811 slides over the pushing rod 813, the lower end position of the triangular bevel groove 811 will be used to contact the extrusion arc block 814, achieving an intermittent squeezing effect, so that the disinfection cotton 804 has a process of squeezing and discharging liquid and rebounding to re-absorb liquid, which is beneficial to improving the effect of squeezing and pushing the disinfectant.

[0045] Furthermore, auxiliary opening and closing components 9 are equidistantly arranged on the top of the four positioning support plates 4, and the auxiliary opening and closing components 9 include support blocks 901, the bottoms of the two support blocks 901 are fixedly connected to the inner walls of the auxiliary grooves 708, and the inner walls of the support blocks 901 are rotatably connected to a rotating rod 902, the outer walls of the rotating rod 902 are rotatably connected to a closing plate 903, and the outer walls of the rotating rod 902 are equidistantly overlapped with torsion springs 904, and the adjacent ends of the two torsion springs 904 are overlapped on the outer walls of the closing plate 903 on both sides.

[0046] In the embodiment, when preparing to take the target culture tube 2, since the microorganisms cultured in the aerobic environment need to continuously transport air into the culture tube 2, the cup cover is a breathable cup cover. Therefore, when all the culture tubes 2 are unlocked, in order to prevent the culture tubes 2 that have not been taken out from being directly invaded by the outside air due to the open mouth, a rotating rod 902 is rotatably connected to the inner wall of the support block 901, and the outer wall of the rotating rod 902 is rotatably connected to the closing plate 903, and the outer wall of the rotating rod 902 is equidistantly overlapped with torsion springs 904, and at the same time, the ends of the two torsion springs 904 that are close to each other are overlapped on the outer walls of the closing plate 903 on both sides, and the extended end of the rotating rod 902 is fixedly connected with a gear 905. , and the top of the positioning support plate 4 is fixedly connected to the corresponding gear 905 with a rack rack 906, and at the same time, one side of the gear 905 is meshed and matched with the top inner wall of the rack rack 906, so that in the process of unlocking, that is, the process of the culture tube 2 moving upward, the two clamping blocks 706 can be approached to each other and synchronously drive the two closing plates 903 to move closer to each other. At the same time, through the cooperation of the gear 905 and the rack rack 906, the rotating rod 902 can drive the two separated closing plates 903 to flip inward synchronously through the torsion spring 904, so that when the culture tube 2 is completely moved up, its top is fitted and closed to prevent all the culture tubes 2 from being exposed to the external environment.

[0047] Furthermore, during the entire upward movement of the culture tube 2, the gear 905 will rotate multiple circles, so that after the two closed plates 903 are merged at one end, the continued rotation of the gear 905 will use the elastic force of the torsion spring 904 to elastically squeeze and limit the two closed plates 903, so that the two closed plates 903 can use the elastic force of the torsion spring 904 and the placement positioning hole 702 to form a smaller clamping effect on the remaining culture tubes 2 again, thereby ensuring their placement stability.

[0048] Next, when taking the target culture tube 2, the index finger and thumb of one hand are respectively placed on the side walls close to the two closing plates 903, and then the two closing plates 903 are manually separated by pushing outward with the index finger and thumb. At this time, the target culture tube 2 can be taken with the other hand, and the same applies to placing it.

[0049] The working principle of the present invention is as follows: when it is necessary to take out the target culture tube 2 in the device, first open the door of the culture box 1, then start the electric push rod 6, and the electric push rod 6 and the mounting plate 5 are used to synchronously drive the multiple support bases 701 to move upwards, and when the support bases 701 move upwards, the culture tube 2 located in the placement positioning hole 702 can be lifted up synchronously, and at the same time, the two clamping blocks 706 can be synchronously driven to move away from each other to release the clamping state through the cooperation of the connecting rod 1 703 and the slider 704;

[0050] When the support base 701 moves up to the top, most of the outer wall of the culture tube 2 is located at the upper part of the positioning hole 702, and the horizontal height of the four positioning support plates 4 rises from the front side to the back side of the incubator 1 in a step-like manner, so that all the culture tubes 2 arranged in the front and back can form a stepped arrangement, so that the distance between adjacent culture tubes 2 is increased, which is convenient for the culture personnel to take the target culture tube 2, reduces the possibility of touching other culture tubes 2, and reduces the risk of displacement;

[0051] When the target culture tube 2 that has passed through the outside is put back to its original position, the positioning hole 702 is arranged to facilitate the rapid placement of the target culture tube 2 at the required clamping position, and then the electric push rod 6 drives the multiple support bases 701 to move downward, at which time the culture tube 2 will follow the downward movement under the action of gravity, and simultaneously drive the two clamping blocks 706 to approach each other and gradually clamp the top outer wall of the culture tube 2;

[0052] During the downward movement of the culture tube 2, the outer wall of the target culture tube 2 passing through the outside can be disinfected by the disinfection cotton 804, so as to avoid the outer wall of the culture tube 2 carrying pollutants after being touched by the culture personnel, reduce the human wiping error, reduce the human intervention link, and simultaneously perform the disinfection step on other culture tubes 2 to take preventive measures;

[0053] During the sterilization process, the push rod 813 can be squeezed by the push block 810. Under the elastic force of the spring 809, the squeezing arc block 814 can be driven by appropriate elastic force to squeeze the sterilization cotton 804. By using this squeezing force, the filling degree of the contact position between the sterilization cotton 804 and the target culture tube 2 can be maintained, thereby ensuring the sterilization effect and improving the experimental accuracy of the device.

[0054] When all the culture tubes 2 are unlocked, in order to prevent the culture tubes 2 that have not been taken out from being directly invaded by external air due to their open openings, during the unlocking process, that is, the process of the culture tubes 2 moving upward, the two clamping blocks 706 can be brought closer to each other and the two closing plates 903 can be moved closer to each other synchronously. At the same time, through the cooperation of the gear 905 and the rack rack 906, the rotating rod 902 can drive the two separated closing plates 903 to flip inward synchronously through the torsion spring 904, so that when the culture tubes 2 are completely moved up, their tops can be fitted and sealed to prevent all the culture tubes 2 from being exposed to the external environment.

[0055] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
