[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention;

[0030] See also Figure 1-3 In the utility model, a culture device for molecular biology research includes a culture dish 1, a top cover 2 is arranged inside the culture dish 1, a fixed cover 3 connected to the top cover 2 is installed on the top cover 2, a liquid injection hole 4 is opened on the top of the fixed cover 3, and a liquid guide component 5 is arranged inside the fixed cover 3.

[0031] In the utility model, the culture dish 1 and the top cover 2 form the main body of the culture device. The user can pre-introduce the nutrient solution into the fixed cover 3 along the injection hole 4. During use, the liquid guide component 5 in the fixed cover 3 can be used to quickly transport the nutrient solution into the culture dish 1, which is convenient to use.

[0032] See also Figure 1-3 , wherein: the liquid guide component 5 includes a fixed plate 51, two hinged plates 52, two metal sliders 53 and two pull ropes 54, the two hinged plates 52 are hinged to the inside of the fixed plate 51 and the opposite sides are in contact, the fixed plate 51 is installed to the inside of the fixed cover 3, the metal slider 53 is slidably connected to the bottom of the fixed plate 51, one end of the pull rope 54 is fixedly connected to the outside of the metal slider 53, and the other end of the pull rope 54 is fixedly connected to the bottom of the hinged plate 52, and the outside of the fixed cover 3 is provided with a magnetic ring 6 slidably connected to it.

[0033] In the utility model, when it is necessary to introduce nutrient solution, the user can push the magnetic ring 6 upward along the fixed cover 3, and use the magnetic force of the magnetic ring 6 to attract the metal slider 53 to make it slide along the bottom of the fixed plate 51. During the sliding process, the pull rope 54 will pull the hinged plate 52 to move, so that a guide port is formed on the fixed plate 51, which is convenient for the nutrient solution to be discharged downward.

[0034] See also Figure 1-3 , wherein: two elastic ropes 7 are fixedly connected to the top of the fixed plate 51 , and one end of the elastic rope 7 is fixedly connected to the top of the hinged plate 52 .

[0035] In the present invention, after each liquid guiding operation is completed, the user can move the magnetic ring 6 to its original position, at which time the magnetic ring 6 is no longer adsorbed to the metal slider 53, and then the elastic rope 7 pulls the hinge plate 52 to reset, so that the two hinge plates 52 are closed, and the guiding of the nutrient solution is ended.

[0036] See also Figure 1-3 , wherein: a partition plate 8 located above the fixed plate 51 is fixedly connected to the interior of the fixed cover 3 , and a group of through holes 9 are opened inside the partition plate 8 .

[0037] In the utility model, the partition 8 is used to support and store the nutrient solution introduced into the fixed cover 3. After the two hinged plates 52 are reset and closed each time, the nutrient solution on the partition 8 will slowly flow into the fixed plate 51 along the through hole 9 to accumulate the nutrient solution, which is convenient for the next introduction of the nutrient solution.

[0038] See also Figure 1-2 , wherein: a vertical pipe 10 connected to the top cover 2 is installed on the top, and a sealing plug is arranged on the outside of the vertical pipe 10.

[0039] In the present invention, the user can choose whether to use a sealing plug to block and seal the vertical tube 10 according to the type of cultured organisms, thereby adjusting the air tightness inside the culture dish 1 so that the internal culture environment is suitable for aerobic organisms and anaerobic organisms.

[0040] See also Figure 1-2 , wherein: a group of docking holes 11 are opened on the top of the culture dish 1, and a group of docking rods 12 are installed on the bottom of the culture dish 1.

[0041] In the present invention, the docking rod 12 and the docking hole 11 are arranged in combination, so that when a plurality of culture dishes 1 are used, they can be stably stacked and placed, thereby reducing the occupied area.

[0042] See also Figure 1-2 , wherein: a magnifying lens 13 is embedded inside the top cover 2, and two handles are installed on the top of the top cover 2.

[0043] In the utility model, a handle is used to facilitate taking and placing the top cover 2 , and the arrangement of the magnifying lens 13 facilitates the user to observe the culture conditions inside the culture dish 1 .

[0044] See also Figure 1-2 , wherein: a sealing ring 14 and a gasket ring 15 are sequentially installed inside the culture dish 1 from top to bottom, and the top cover 2 is located between the sealing ring 14 and the gasket ring 15 .

[0045] In the present invention, the gasket ring 15 is used to support the top cover 2, and the sealing ring 14 is arranged to ensure the air tightness inside the culture dish 1 on the one hand, and to resist the top cover 2 on the other hand to ensure its stability.

[0046] It should be noted that the various devices in this application are common devices in the market, and can be selected according to specific needs during specific use. The circuit connection relationship of each device belongs to a simple series and parallel connection circuit. There is no innovation in the circuit connection. Those skilled in the art can easily implement it. It belongs to the existing technology and will not be elaborated.

[0047] Working principle: The main body of the culture device is composed of a culture dish 1 and a top cover 2. The top cover 2 is supported by a gasket ring 15. The sealing ring 14 can ensure the airtightness of the inside of the culture dish 1 on the one hand, and resist the top cover 2 on the other hand to ensure its stability. The user can place the cultured organisms in the culture dish 1. The user can choose whether to use the sealing plug to block and seal the vertical pipe 10 according to the type of cultured organisms, so as to adjust the airtightness inside the culture dish 1 so that the internal culture environment is suitable for aerobic organisms and anaerobic organisms. The user can pre-introduce the nutrient solution into the fixed cover 3 along the injection hole 4. When the nutrient solution needs to be introduced, the user can push the magnetic ring 6 upward along the fixed cover 3, and use the magnetic force of the magnetic ring 6 to absorb the metal slider 53 to slide along the bottom of the fixed plate 51. During the sliding process, the pull rope 54 will pull the hinged plate 52 to move, so that a guide port is formed on the fixed plate 51 to facilitate the downward discharge of the nutrient solution. After each liquid guiding operation is completed, the user can move the magnetic ring 6 to its original position. At this time, the magnetic ring 6 is no longer adsorbed on the metal slider 53, and then the elastic rope 7 will pull the hinge plate 52 to reset, so that the two hinge plates 52 are closed, and the nutrient solution is guided out. The partition 8 is used to support and store the nutrient solution introduced into the fixed cover 3. After the two hinge plates 52 are reset and closed each time, the nutrient solution on the partition 8 will slowly flow into the fixed plate 51 along the through hole 9 to accumulate the nutrient solution for the next nutrient solution introduction. The docking rod 12 and the docking hole 11 are arranged in combination, so that when multiple culture dishes 1 are used, they can be stably stacked and placed to reduce the occupied area. The entire device can transport the culture solution to the inside of the culture dish 1 multiple times without opening the top cover 2, thereby reducing the user's labor and improving the convenience of operation. The air tightness of the culture dish 1 can be adjusted according to the type of organism to meet the culture environment, making it more practical.

[0048] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
