DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0021] like Figures 1 to 7 As shown, the present invention includes the following embodiments: Embodiment 1:

[0022] A microorganism cultivation device, comprising an incubator 1 and an environment adjustment component 2 in the incubator 1; the environment adjustment component 2 comprises a heating unit, a temperature sensor, a temperature regulator, an image collector and a light source emitter; a groove 11 is arranged on the upper surface of the incubator 1; the groove 11 is slidably sealed and connected to an active plate 3 up and down; the upper end surface of the active plate 3 is fixedly connected to a top plate 4 through a vertical bar 31; the top plate 4 is slidably sealed and connected to the groove 11; the environment adjustment component 2 is connected to the inner side of the vertical bar 31; an electromagnetic valve 32 is arranged through the upper and lower parts of the active plate 3; a slide groove 12 is vertically arranged on the groove wall of the groove 11; a slider 13 is slidably sealed and connected to the slide groove 12; the slider 13 is fixedly connected to the edge of the active plate 3; the slider 13 passes through the screw 14 up and down and is threadedly driven and sealed; the screw 14 is fixedly connected to a motor 15 at the lower end; during the downward movement of the active plate 3, the gas temporarily stored in the groove 11 can push away the gas between the active plate 3 and the top plate 4; the cultivation device is controlled and operated by a controller; During operation, when using the constant temperature incubator 1 to cultivate microorganisms, it is necessary to regularly take out the culture dish in the constant temperature incubator 1 and check the growth status of the microorganisms so as to make targeted adjustments. After completing the status check of the microorganisms, the culture dish will be put back into the constant temperature incubator 1. Each time the culture dish is taken out and placed in the constant temperature incubator 1, the door of the constant temperature incubator 1 will be opened, which will cause the gas inside and outside the constant temperature incubator 1 to mix, so that the culture environment in the constant temperature incubator 1 is destroyed, affecting the subsequent culture effect of the microorganisms; Therefore, after the staff of the present invention puts the microorganisms into the culture dish filled with culture solution, they close the lid of the culture dish and then start the button to control the motor 15 to work. During the rotation of the motor 15, the screw 14 will be driven to rotate. The contact part of the screw 14 and the incubator 1 is a rotating sealed connection, and the part connected with the screw 14 and the slider 13 is connected with the threaded transmission sealing connection of the slider 13. Therefore, the rotation of the screw 14 can drive the slider 13 to move up in the slide groove 12. During the upward movement of the slider 13, the connected active plate 3 can be driven to move up. During the upward movement of the active plate 3, the vertical bar 31 and the top plate 4 will be driven to move up until the active plate 3 moves up and is flush with the upper surface of the incubator 1. Then the staff places the culture dish on the upper surface of the active plate 3 and then controls another button to drive the motor 15 to rotate in the opposite direction. The principle of the button driving the motor 15 is the prior art and will not be repeated here. During the reverse rotation of the motor 15, the screw 14 will be driven to rotate in the opposite direction, so that the slider 13 14 is driven to move down along the slide groove 12, and the slider 13 will drive the active plate 3 to move down. During the downward movement of the active plate 3, the vertical bar 31 and the top plate 4 will be driven to move down until the active plate 3 moves down to the lower limit position. The top plate 4 and the active plate 3 are sealed with the groove wall of the groove 11, so the first chamber 34 is in a sealed state. In this way, the environmental adjustment component 2 will adjust the living environment of the microorganisms in the first chamber 34 so that the microorganisms can be cultured. After the microorganisms are cultured for a period of time, the staff needs to check the microorganisms, specifically, pressing one of the buttons to drive the motor 15 to rotate forward. During the forward rotation of the motor 15, the screw 14 will be driven to rotate. During the rotation of the screw 14, the slider 13 will be driven to move up along the slide groove 12. During the upward movement of the slider 13, the active plate 3 will be driven to move up in the groove 11, so that the space in the second chamber 33 becomes larger to form a negative pressure. For the convenience of description, the gas in the first chamber 34 adjusted by the environmental adjustment component 2 is called culture gas;In the process of the space in the second chamber 33 becoming larger and forming a negative pressure, the culture gas in the first chamber 34 will enter the second chamber 33 along the opened electromagnetic valve 32. In the process of the electromagnetic valve 32 generating a negative pressure, the top plate 4 will also be exposed from the upper end of the groove 11, so that the external gas will enter the first chamber 34 along the upper end of the groove 11, and the original culture gas in the first chamber 34 will be sucked into the second chamber 33 by the electromagnetic valve 32 for temporary storage. After the upper surface of the active plate 3 moves to be flush with the upper surface of the incubator 1, the electromagnetic valve 32 is temporarily closed. After that, after the staff completes the inspection of the microorganisms in the culture dish, they put the multiple culture dishes back to their original positions and press the second button, so that the motor 15 rotates in the opposite direction to drive the screw 14 to rotate in the opposite direction. The rod 14 is reversed, and the slider 13 and the active plate 3 are driven to move downward during the reverse rotation of the screw rod 14. During the downward movement of the active plate 3, the space in the second chamber 33 becomes smaller, so that the culture gas temporarily stored in the second chamber 33 is pressurized to enter the first chamber 34 along the opened electromagnetic valve 32, thereby squeezing the external gas in the first chamber 34 along the upper end of the groove 11 until the top plate 4 moves down to the inner side of the groove 11, so that the culture gas in the first chamber 34 is not changed too much by the inspection of the microorganisms as much as possible. After the inspection of the microorganisms is completed, the culture gas returned to the first chamber 34 continues to provide a good living environment for the microorganisms in the culture dish, thereby improving the culture efficiency and effect of the microorganisms; The present invention absorbs the culture gas in the first cavity 34 for temporary storage through the second cavity 33 during the upward movement of the active plate 3, and replaces the external gas in the first cavity 34 during the return process after the microbial inspection, thereby reducing the impact of the external gas on the culture environment after the microbial inspection and improving the culture efficiency and effect of the microorganisms.

[0023] Embodiment 2: The depth of the groove 11 is twice the distance between the mutually distant surfaces of the top plate 4 and the active plate 3; the active plate 3 is located at the lower position of the groove 11 in the state of culturing microorganisms; a first cavity 34 is formed between the active plate 3 and the top plate 4; a second cavity 33 is formed between the active plate 3 and the bottom of the groove 11; the lower surface of the top plate 4 is fixedly connected to the upper capsule 41; the upper capsule 41 is made of elastic material; the top of the top plate 4 is connected to an air pump 42 connected to the inside of the upper capsule 41; the air pump 42 and the motor 15 are controlled by a controller.

[0024] In this embodiment, the bottom of the groove 11 is fixedly connected to the elastic lower bag 5; the inner wall of the incubator 1 is provided with an L-shaped groove 16; the upper end of the L-shaped groove 16 is connected to the upper end surface of the incubator 1, and the lower end is connected to the inside of the lower bag 5.

[0025] In this embodiment, the vertical bar 31 is arranged in contact with the inner wall of the groove 11; the lateral groove wall of the groove 11 is provided with a movable groove 17; the movable groove 17 is horizontally slidably connected to the movable block 6; one end of the movable block 6 is connected to the bottom of the movable groove 17 by a first spring 61; the other end of the movable block 6 is inclined downward and provided with an inclined surface 62; the movable groove 17 is arranged close to the groove opening of the groove 11; the movable groove 17 penetrates and cuts off the L-shaped groove 16; the movable block 6 is penetrated by a connecting groove 63 from top to bottom; the connecting groove 63 opens the L-shaped groove 16 after the other end of the movable block 6 is pressed; During operation, in the microbial culture state, the active plate 3 is located at the lower limit position, that is, close to the bottom of the groove 11, and the top plate 4 is also out of contact with the movable block 6, so that the movable block 6 extends from the notch of the movable groove 17 under the action of the first spring 61, and the movable block 6 intercepts and blocks the L-shaped groove 16, so that the L-shaped groove 16 is closed, so that the lower capsule 5 is in a closed state. When the staff needs to conduct a microbial inspection, the active plate 3 moves up to enlarge the space of the second cavity 33 to form a negative pressure. Since the L-shaped groove 16 is closed, the outside gas cannot enter the lower capsule along the L-shaped groove 16 5, and makes the lower bag 5 bulge, so the upward movement of the active plate 3 will only make the culture gas in the first chamber 34 be pressurized and enter the second chamber 33 along the opened first electromagnetic valve. Since the depth of the groove 11 is twice the distance between the active plate 3 and the top plate 4, during the upward movement of the active plate 3 and the top plate 4, the culture gas in the first chamber 34 is drawn into the second chamber 33 without contacting the outside gas in the first chamber 34. Compared with the original transfer of the culture gas in the first chamber 34 after leakage, the purity of the culture gas transferred in the first chamber 34 is improved, and the influence of the subsequent outside gas on the culture environment is further reduced; During the process of the culture gas in the first chamber 34 entering the second chamber 33 along the opened electromagnetic valve 32, the controller controls the air pump 42 to work, and the air pump 42 fills the external gas into the upper bag 41, so that the upper bag 41 swells. During the swelling process, the upper bag 41 fills the position where the culture gas in the first chamber 34 is drawn away, and pushes the culture gas in the first chamber 34, so that the culture gas in the first chamber 34 can be quickly transferred to the second chamber 33 under the push of the upper bag 41 and the negative pressure of the electromagnetic valve 32, thereby indirectly improving the inspection efficiency of microorganisms; because the upper bag 41 can fill the first chamber 34 after expansion, the gas in the first chamber 34 is completely drawn into the second chamber 33, completing the complete transfer process of the culture gas in the first chamber 34, and the controller controls the electromagnetic valve 32 to open. 32 is closed, and when the top plate 4 moves up to a position close to the notch of the groove 11, the top plate 4 pushes the inclined surface 62 at the other end of the movable block 6, so that the movable block 6 is under pressure to overcome the first spring 61 and retract into the movable groove 17. In the process of retracting the movable block 6 into the movable groove 17, the connecting hole on the movable block 6 is connected with the L-shaped groove 16, so that the L-shaped groove 16 is in an open state. In this way, when the top plate 4 continues to move up and exposes the notch of the groove 11, the space in the second chamber 33 continues to expand to form a negative pressure, so that the external gas enters the lower bag 5 along the L-shaped groove 16, so that the lower bag 5 bulges. In the process of the lower bag 5 bulging, the gas pressure in the second chamber 33 can be balanced, thereby reducing the running resistance caused by the upward movement of the active plate 3 and improving the upward movement efficiency of the active plate 3. After the top plate 4 moves up and is exposed from the notch of the groove 11, the controller controls the air pump 42 to extract the gas in the upper bag 41, so that the upper bag 41 changes from a bulging state to a deflated state, and the outside air will also enter the first cavity 34. When the upper surface of the active plate 3 moves up and is flush with the upper surface of the incubator 1, the motor 15 stops running, the staff inspects the microorganisms in the culture dish, and puts it back on the upper surface of the active plate 3 after the inspection, and then the controller controls the active plate 3 to move down. The downward movement of the active plate 3 will increase the air pressure in the second cavity 33, so that the internal gas of the lower bag 5 is discharged along the L-shaped groove 16, and the lower bag 5 also changes from a bulging state to a deflated state. When the top plate 4 moves down with the active plate 3 to close the notch of the groove 11, the air pump 42 is turned on to fill the outside air into the upper bag 41, so that the upper bag 41 will let the outside air in the first cavity 34 flow away along the gap between the top plate 4 and the notch of the groove 11 during the bulging process, and the active plate 3 will continue to move down and drive the top plate 4 is retracted to the inner side of the notch of the groove 11, so that the first chamber 34 is closed. As the active plate 3 and the top plate 4 continue to move downward, the top plate 4 will separate from the movable block 6, and the first spring 61 will push the movable block 6 to move toward the outside, so that the connecting groove 63 on the movable block 6 is staggered with the L-shaped groove 16, so that the L-shaped groove 16 is closed, and the lower capsule 5 is also in a closed state. When the top plate 4 moves to the inner side of the notch of the groove 11, the electromagnetic valve 32 is opened, and the active plate 3 and the top plate 4 continue to move downward, so that the culture gas in the second chamber 33 enters the first chamber 34 along the opened electromagnetic valve 32. At the same time, the air pump 42 extracts the gas in the upper capsule 41. The shrinking process of the upper capsule 41 will also form a negative pressure in the first chamber 34, so that the culture gas in the second chamber 33 is transferred under the dual effects of the negative pressure generated by the upper capsule 41 and the squeezing of the active plate 3 moving downward, until the active plate 3 moves downward to contact with the lower capsule 5, so that the first chamber 34 returns to the microorganism culture state; The present invention moves the active plate 3 upward when the top plate 4 is located in the groove 11, and cooperates with the air pump 42 to inflate the upper bag 41, so that the culture gas in the first cavity 34 is transferred to the second cavity 33 before contacting with the external gas, and returns to the first cavity 34 after the inspection of the microorganisms is completed. Compared with the original transfer of the culture gas in the first cavity 34 during the leakage process, the contamination of the culture gas in the first cavity 34 by the external gas is avoided, the cleanliness of the culture environment of the microorganisms after the inspection is improved, and the subsequent culture efficiency and effect of the microorganisms after the inspection are also improved.

[0026] In this embodiment, the active plate 3 and the top plate 4 move downward, and the top plate 4, the vertical bars 31 and the active plate 3 can squeeze the movable block 6. During the downward movement of the active plate 3 and the top plate 4, the movable block 6 will be squeezed by the active plate 3, the vertical bars 31 and the top plate 4 in turn.

[0027] Embodiment 3: The surfaces of the two vertical bars 31 that are away from each other are in contact with the corresponding groove walls of the groove 11; the position where the vertical bars 31 contact the groove walls of the groove 11 corresponds to the position where the slide groove 12 is set; the outer side of the vertical bar 31 is a side that contacts the groove wall of the slide groove 12; the width of the vertical bar 31 is greater than the width of the slide groove 12; the outer side of the vertical bar 31 can block and seal the position of the slide groove 12 between the top plate 4 and the active plate 3; when working, the active plate 3 is controlled to move up or down by the slider 13 in the slide groove 12, and the top plate 4 will move with the movement of the active plate 3. When the top plate 4 and the active plate 3 move up or down in the groove 11 at the same time, the vertical bar 31 can block the position of the slide groove 12 between the active plate 3 and the top plate 4, thereby ensuring the sealing state of the first cavity 34 when the top plate 4 is located in the groove 11, and ensuring a good sealing effect of the first cavity 34.

[0028] Embodiment 4: The thickness of the upper bag 41 is set to decrease as it moves away from the center of the top plate 4 ; under the action of the air pump 42 , the upper bag 41 first bulges from the part close to the center of the top plate 4 .

[0029] In this embodiment, protrusions 7 are evenly arranged on the upper surface of the active plate 3 ; the distance between adjacent protrusions 7 is smaller than the diameter of the culture dish; and the electromagnetic valve 32 is connected between adjacent protrusions 7 .

[0030] In this embodiment, the upper surface of the active plate 3 is provided with an avoidance groove 35; the protrusion 7 is slidably connected in the avoidance groove 35; the lower end of the protrusion 7 is connected to the bottom of the avoidance groove 35 through an avoidance spring 71; the number of the electromagnetic valves 32 is multiple; During operation, when it is necessary to inspect the microorganisms in the incubator 1, the staff will control the motor 15 to rotate and drive the active plate 3 to move upward. The electromagnetic valve 32 is in an open state under the control of the controller. During the upward movement of the active plate 3, the second chamber 33 will generate negative pressure, which will cause the electromagnetic valve 32 to generate negative pressure. During the upward movement of the active plate 3, the controller will also drive the air pump 42 to work. The air pump 42 will fill the upper capsule 41 with external gas, so that the upper capsule 41 will first swell from the center position close to the top plate 4 during the upward movement of the active plate 3. The upper capsule 41 will be against the protrusion 7 through the culture dish. The setting of the protrusion 7 enables the negative pressure generated by the electromagnetic valve 32 to draw away the culture gas in the gap between the upper capsule 41 and the upper surface of the active plate 3. As the upper capsule 41 continues to expand, the upper capsule 4 1 will cause the protrusion 7 at the center of the active plate 3 to overcome the corresponding avoidance spring 71 and squeeze it toward the avoidance groove 35, so that the surface of the upper capsule 41 directly squeezes the protrusion 7 into the corresponding avoidance groove 35 and blocks some of the surrounding electromagnetic valves 32, so that the electromagnetic valves 32 at other positions continue to form negative pressure, and the electromagnetic valve 32 near the center of the active plate 3 in the first chamber 34 is blocked first, so that the negative pressure of the electromagnetic valves 32 at other positions is more concentrated, and under the multiple effects of the upper capsule 41 expanding and pushing the remaining culture gas in the second chamber 33, the culture gas in the first chamber 34 can be quickly transferred to the second chamber 33, thereby indirectly improving the efficiency of microbial inspection; when the protrusion 7 is pressed into the avoidance groove 35 for avoidance, the culture gas in the first chamber 34 is also transferred more thoroughly; After the culture dish falls on the upper end of the plurality of protrusions 7, the friction between the protrusions 7 and the culture dish is increased, so that the culture dish is not easily displaced during the squeezing process by the upper capsule 41, thereby improving the stability of the culture dish placed on the active plate 3. After the upper capsule 41 expands, it can also cooperate with the protrusion 7 under the dual action of the avoidance spring 71 to complete the clamping of the culture dish, so that the culture dish is not easily shaken during the upward movement of the active plate 3, thereby further improving the stability of the microorganisms in the culture dish. After the upper surface of the active plate 3 moves up to be flush with the upper surface of the incubator 1, the air pump 42 controls the upper capsule 41 to deflate, and the protrusion 7 moves out of the corresponding avoidance groove 35 under the action of the avoidance spring 71. The protrusion 7 will lift the culture dish, so that a picking gap is formed between the bottom of the culture dish and the upper surface of the active plate 3, thereby improving the efficiency of the staff in picking up the culture dish and reducing the operation time of the staff in inspecting the microorganisms. After completing the inspection of the microorganisms, the top plate 4 will move down with the downward movement of the active plate 3. The upper capsule 41 can also begin to expand during the downward movement of the top plate 4, and when a small gap is formed between the top plate 4 and the notch of the groove 11, the upper capsule 41 completes the remaining expansion work, and the upper capsule 41 expands from the center of the top plate 4 toward the edge, so that the external gas in the first cavity 34 is discharged more thoroughly from the notch of the groove 11. After the top plate 4 is lower than the notch of the groove 11, the lower capsule 5 deflates under control; during the deflation process of the lower capsule 5, some culture dishes will also be clamped.
