Description

Technical Field

[0001] The present invention relates to the technical field of microbial agent cultivation, and in particular to a microbial agent cultivation instrument. Background Art

[0002] Before culturing microbial inoculants, the microorganisms need to be extracted and inoculated into the culture medium. During this process, a limit meter is required. After use, the user transfers the filter membrane into the culture medium.

[0003] During the operation of inoculating microorganisms, when using tools to transfer the filter membrane, microorganisms in the surrounding air may settle on the filter membrane or culture medium, causing contamination. Even in a relatively clean environment, such as the air conditioning wind in an ordinary laboratory, the airflow caused by the movement of people, etc., may carry tiny particles and microorganisms, increasing the risk of contamination, resulting in the failure of the final cultivation of microbial agents, or unsatisfactory cultivation effects. After the inoculation is completed, nutrient solution needs to be regularly added to the culture medium with microbial agents to meet the growth needs of the microbial agents. However, it is difficult to ensure that the nutrient solution is evenly covered in the culture medium when it is added to the culture medium. Therefore, an oscillating instrument is required to mix the microbial agents and the nutrient solution. In the process of taking the culture medium out of the culture instrument and oscillating it, the air flow is driven when the culture instrument is opened, which increases the risk of impurities in the air entering the culture medium and causing contamination. In addition, some microorganisms may die due to long-term temperature changes, which has an adverse effect on the cultivation effect of the microbial agents.

[0018] As described above, the characteristics and advantages of the culture instrument for microbial inoculants in the present invention are:

[0019] By setting the quantitative rotating component and the culture medium lifting component, the culture medium can be driven to rise until the culture medium contacts the push ring and is fixed at the bottom of the push ring. When the culture medium is at the bottom of the push ring, the height difference when the filter membrane falls from the fixed tube is small, and the filter membrane will not be impacted when it contacts the culture medium due to the excessive height difference, thereby preventing the microorganisms on the filter membrane from splashing during the impact, and preventing the filter membrane from wrinkling during the impact. At the same time, the filter membrane with bacteria is directly transferred to the culture medium under the action of gravity, and the operator does not need to use tools to manually transfer the filter membrane to the culture medium, thereby simplifying the microbial filtration process while ensuring the standardization of the operation of placing the filter membrane into the culture medium. At the same time, when nutrient solution needs to be added, the specified culture medium can be raised to the bottom of the fixed tube. At this time, the baffle is opened under the action of the push plate, and the operator can extend the syringe into the fixed tube and squeeze the nutrient solution into the culture medium, so that nutrient solution can be added to the culture medium without opening the incubator, avoiding the risk of contamination caused by air flow when the incubator is opened.

[0020] By setting the quantitative rotating assembly, two dislocated paddles successively push the fixed teeth through the inclined plane, so that the fixed teeth drive the rotating circle to rotate under the cooperation of the inclined plane, thereby driving the turntable to rotate intermittently and at a small distance during the continuous rotation of the disc, so that the culture medium and the liquid collection bottle can be accurately rotated to the bottom of the fixed tube, so as to accurately control the container at the bottom of the fixed tube, and then achieve the effect of automatic switching during the use of the device, which is convenient for use and ensures the accuracy of the operation of inserting the strain, and also avoids the problem of confusion when injecting the solution due to multiple culture media and liquid collection bottles during manual operation, thereby effectively classifying different strains;

[0021] Through the setting of the microbial filtration component, when the push ring rotates accurately and quickly to the bottom of the fixed tube, the two baffles are fully opened, and the filter membrane that loses its limit falls into the culture medium, thereby automatically completing the operation of placing the filter membrane into the culture medium. There is no need to manually transfer the filter membrane. A flamethrower is used to sterilize the inside of the fixed tube in the interval between different culture media, so as to achieve the effect of guiding users to perform bacterial filtration operations in accordance with specifications, improve the convenience of use, and avoid the occurrence of irregular operations, which is beneficial to the effect of microbial inoculant cultivation, and automatically falls into the filter membrane, avoiding the problem of cross-infection of other contaminated bacteria when picking up manually;

[0022] Through the setting of the wave plate, when the roller rolls upward on the wave plate, the two rollers prop up the turntable upward, so that the turntable pulls spring 2 through the hexagonal rod, so that spring 2 stretches, and when the roller rolls downward on the wave plate, the turntable moves downward under the action of its own gravity and the tightening of spring 2, so that the turntable continuously moves up and down during the rotation process, thereby achieving an oscillation effect, and then after the nutrient solution is added to the culture medium, the nutrient solution and the microorganisms are evenly mixed, thereby preventing the growth of microorganisms from being affected by uneven flow of the nutrient solution.

[0047] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows:

[0048] The initial state is:

[0049] A clean culture medium is installed in the culture medium seat 3, a liquid collection bottle 5 is installed in the bottle seat 4, and the spring 1 605 is extended, so that the slider 604 is located on the side of the fixed frame 603 close to the fixed tube 601, and the two baffles 606 are in contact, so that the bottom of the fixed tube 601 is closed, the push ring 610 is not in contact with the push block 608, the motor 705 is not started, and the lifting seat 804 is not raised, so that the lever 805 is located below the turntable 2, the roller 904 is located in the depression of the wave plate 902, and the spring 2 905 is not unfolded.

[0050] The working status is:

[0051] Turntable 2 quantitatively rotates to switch between culture medium and collection bottle 5:

[0052] When switching the container aligned with the bottom of 601, the motor 705 is started to make its output shaft rotate counterclockwise, so that the motor 705 drives the disk 706 on the output shaft to rotate under the action of the ratchet pawl mechanism 1, thereby making the disk 706 drive the rotating rod 707 to make eccentric movement. At this time, the reciprocating block 709 at the other end of the rotating rod 707 is pulled and slid, so the rotation of the disk 706 drives the reciprocating block 709 to slide back and forth in the fixed frame 708 through the rotating rod 707. When the reciprocating block 709 moves back and forth, the two misaligned paddles 710 successively push the fixed teeth 704 through the inclined surface, so that the fixed teeth 704 drive the rotating circle 703 to rotate under the cooperation of the inclined surface, thereby driving the turntable 2 to rotate intermittently and at a small distance during the continuous rotation of the disk 706, thereby achieving the effect of accurately aligning different containers with the bottom of the fixed tube 601, and then achieving the effect of automatic switching during the use of the device, which is convenient for use while ensuring the accuracy of the operation of inserting the strain.

[0053] To raise the medium to the bottom of the stationary tube:

[0054] When the filter membrane needs to be placed in the culture medium, the motor 705 is started to rotate its output shaft clockwise, thereby driving the pulley 1 801 to rotate under the action of the ratchet pawl mechanism 2, thereby driving the pulley 2 802 to rotate under the action of the belt, so that the pulley 2 802 drives the reciprocating screw 803 to rotate, thereby driving the lifting seat 804 to rise upward, and the lever 805 passes through the toggle groove 806 provided on the turntable 2 when rising upward, and then lifts the culture medium from the bottom of the culture medium in cooperation with the toggle groove 806, and drives the culture medium to rise upward under the drive of the reciprocating screw 803 until the culture medium contacts the push ring 610, at which time the motor 705 stops. The pulley 802 stops rotating, so that the lever 805 presses against the culture medium and fixes it at the bottom of the push ring 610. When the culture medium is at the bottom of the push ring 610, the height difference when the filter membrane falls from the fixed tube 601 is small, and the filter membrane will not be impacted when in contact with the culture medium due to the excessive height difference, thereby preventing the microorganisms on the filter membrane from splashing during the impact, and also preventing the filter membrane from wrinkling during the impact. Compared with the existing process for making bacterial culture medium that requires the use of more instruments, there is no need to use multiple sets of instruments, and the operation of manually transferring the filter membrane using tools is optimized, which simplifies the microbial filtration process while ensuring the standardization of the operation of placing the filter membrane into the culture medium.

[0055] Filter liquid and automatically drop the filter into the culture medium:

[0056] When it is necessary to add the microorganisms to be cultured into the culture medium, the filter membrane is placed in the fixed tube 601, and the motor 705 is used to switch the liquid collecting bottle 5 to the position directly below the fixed tube 601. At this time, the filter membrane falls onto the two baffles 606 under the action of gravity, and then the funnel used to introduce the liquid is screwed onto the threaded tube 602, and then the liquid containing the microorganisms is poured in, so that the liquid rinses the filter membrane and falls into the liquid collecting bottle 5 through the liquid outlet 607 on the baffle 606, so as to achieve the effect of collecting waste liquid. After the liquid is poured in, the microorganisms in the liquid are retained on the filter membrane under the filtering effect, and all the waste liquid enters the liquid collecting bottle 5 for collection. At this time, the motor 705 is used to drive the turntable 2 to rotate counterclockwise, so that the push ring 610 on the top of the culture medium first contacts the push block 608, and then the outer arc surface of the push ring 610 cooperates with the inclined surfaces of the two push blocks 608, so that the push block 6 08 pushes the baffle 606, so that the baffle 606 drives the slider 604 to slide in the fixed frame 603 to the side away from the fixed tube 601 and squeezes the spring 1 605. When the push ring 610 rotates to the bottom of the fixed tube 601, the two baffles 606 are fully opened. At this time, the filter membrane that loses its limit falls into the culture medium, thereby completing the operation of placing the filter membrane into the culture medium. In the interval between placing different culture media, the operator uses a flamethrower to sterilize the inside of the fixed tube 601, which can achieve the effect of guiding the user to perform the bacterial filtration operation in accordance with the specifications, simplifies the operation of the operator using tools to place the filter membrane on the limit meter for filtration, and does not require the operator to use tools to transfer the filter membrane from the limit meter to the culture medium and place it flat, thereby improving convenience and avoiding the occurrence of irregular operations, which is beneficial to the effect of microbial inoculant cultivation.

[0057] Remove the collected waste liquid:

[0058] During the process of placing multiple sets of filter membranes, waste liquids of different microorganisms are filtered out from the liquid outlet 607 and flow down, into different liquid collecting bottles 5 and stored. After the filter membranes are placed, the device can be opened and all the liquid collecting bottles 5 containing waste liquid can be taken out at one time, and then processed uniformly, which helps to simplify the cultivation process of microbial inoculants. Compared with traditional limit meters that require multiple one-way valves to be set inside, there is no need to set a one-way valve, and there is no need for the operator to manually rotate the switch, so as to achieve the effect of avoiding the backflow of waste liquid. Compared with the use of multiple sets of instruments, the use and manufacturing costs of the instruments are reduced, and the situation that the one-way valve in the limit meter is difficult to clean can be avoided.

[0059] To provide mixing of the medium after adding the nutrient solution:

[0060] During the cultivation of microbial inoculants, nutrient solution needs to be added regularly. The motor 705 is started and rotated counterclockwise to transfer the culture medium to which the nutrient solution needs to be added to the bottom of the fixed tube 601. At this time, the push ring 610 above the culture medium pushes the two push blocks 608 to open the two baffles 606. The motor 705 is started and rotated clockwise, so that the lever 805 raises the culture medium to the bottom of the fixed tube 601. At this time, the syringe filled with nutrient solution is inserted into the fixed tube 601 to add nutrient solution to the culture medium. After the nutrient solution is added to the culture medium, the culture medium and the lever 805 are reset. Then the motor 705 is started and rotated counterclockwise to drive the turntable 2 to rotate. The roller 904 at the bottom of the turntable 2 rolls along the wave plate 902. When the roller 904 rolls upward on the wave plate 902, the two rollers 904 prop up the turntable 2, so that the turntable 2 pulls the spring 2 905 through the hexagonal rod 702, so that the spring 2 905 stretches. When the roller 904 rolls downward on the wave plate 902, the turntable 2 moves downward under the action of its own gravity and the tightening of the spring 2 905, so that the turntable 2 continuously moves up and down during the rotation process, thereby achieving an oscillation effect, and then after the nutrient solution is added to the culture medium, the nutrient solution and the microorganisms are evenly mixed, thereby preventing the growth of microorganisms from being affected by the uneven flow of the nutrient solution.
