[0002] Microbial culture requires the consumption of oxygen, nitrogen, nitrogen dioxide, etc., so it is necessary to continuously supply gas to the microbial culture system. Currently, gas is supplied to the microbial culture system through a single pipe. When multiple gases are involved, multiple pipes are required, which are messy, bulky, and inconvenient to control the gas. Utility Model Content

[0003] The technical problem to be solved by this invention is to provide an air supply structure for a microbial culture system, addressing the shortcomings of existing technologies.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] A gas supply structure for a microbial culture system includes at least one gas supply module. The gas supply module includes an auxiliary manifold, a control board, proportional valves, and flow detectors. The number of control boards, proportional valves, and flow detectors is the same, and the number of control boards, proportional valves, and flow detectors can be one or more. The proportional valves and flow detectors are respectively connected to the control board. The auxiliary manifold has an auxiliary air intake channel, a guide channel, and a connecting channel. The number of auxiliary air intake channels and guide channels is equal to the number of proportional valves. One end of each proportional valve is connected to the auxiliary air intake channel, and the other end is connected to the guide channel. The other end of the guide channel is connected to the flow detector, and the other end of the flow detector is connected to the connecting channel.

[0006] In a preferred embodiment, the number of control panels, proportional valves, and flow detectors is 2 to 5, and the connection channels are sequentially connected to adjacent flow detectors.

[0007] In a preferred embodiment, the number of the control panel, proportional valve, and flow detector is three: one auxiliary air intake channel is connected to the oxygen supply structure, one auxiliary air intake channel is connected to the nitrogen supply structure, and one auxiliary air intake channel is connected to the carbon dioxide supply structure.

[0008] A preferred embodiment is that the air outlet of the connection channel is connected to a first quick connector.

[0009] A preferred embodiment is that the gas supply structure of the microbial culture system further includes a main manifold, and there are multiple gas supply modules. The main manifold is provided with several main air intake channels, the number of which is equal to the number of auxiliary air intake channels. The auxiliary air intake channel at the corresponding position in each gas supply module is connected to the main air intake channel.

[0010] A preferred embodiment is that each of the main air intake channels is connected to a second quick connector at its intake end.

[0011] The gas supply structure of the microbial culture system provided in this embodiment of the invention has at least the following beneficial effects: During the cultivation of microorganisms, various gases, such as oxygen, nitrogen, and carbon dioxide, need to be continuously added. When gas needs to be added to the microbial culture system, the gas enters through the auxiliary gas inlet channel, the proportional valve opens, and the gas passes through the proportional valve into the guide channel. The gas in the guide channel enters the flow detector, which can detect the gas flow rate. The gas in the flow detector then enters the microbial culture system. The flow detector can detect the gas flow rate. When the microbial culture system lacks gas, the control board controls the proportional valve to open, increasing the gas in the microbial culture system; when the gas in the microbial culture system is sufficient, the control board controls the proportional valve to close. This allows for convenient addition of various gases to the microbial culture system, is compact, and integrated; it can supply gas to multiple microbial systems.

[0020] like Figures 1 to 4 As shown in the illustration, this application provides an air supply structure for a microbial culture system, comprising at least one air supply module 10. The air supply module 10 includes an auxiliary manifold 11, a control board 12, proportional valves 13, and flow detectors 14. The number of control boards 12, proportional valves 13, and flow detectors 14 is the same, and the number of control boards 12, proportional valves 13, and flow detectors 14 can be one or more. The proportional valves 13 and flow detectors 14 are respectively connected to the control board 12. The auxiliary manifold 11 is provided with an auxiliary air intake channel 111, a guide channel 112, and a connecting channel 113. The number of auxiliary air intake channels 111 and guide channels 112 is equal to the number of proportional valves 13. One end of each proportional valve 13 is connected to the auxiliary air intake channel 111, and the other end is connected to the guide channel 112. The other end of the guide channel 112 is connected to the flow detector 14, and the other end of the flow detector 14 is connected to the connecting channel 113. This structure is small in size and integrated; it can supply air to multiple microbial systems.

[0021] like Figures 1 to 4As shown, during the cultivation of microorganisms, various gases, such as oxygen, nitrogen, and carbon dioxide, need to be continuously added. When gas needs to be added to the microbial cultivation system, the gas enters through the auxiliary gas inlet channel 111, the proportional valve 13 opens, and the gas passes through the proportional valve 13 into the guide channel 112. The gas in the guide channel 112 enters the flow detector 14, which detects the gas flow rate. The flow detector 14 can detect the gas flow rate. When the microbial cultivation system lacks gas, the control panel 12 controls the proportional valve 13 to open, increasing the gas in the microbial cultivation system; when the microbial cultivation system has sufficient gas, the control panel 12 controls the proportional valve 13 to close, allowing for convenient addition of various gases to the microbial cultivation system.

[0022] like Figures 1 to 4 As shown, adjacent auxiliary air intake passages 111 can be supplied with the same gas or different gases.

[0023] like Figures 1 to 4 As shown, the number of control panels 12, proportional valves 13 and flow detectors 14 is 2 to 5, and the connection channel 113 is connected to the adjacent flow detectors 14 in sequence.

[0024] like Figures 1 to 4 As shown, each control panel 12 controls a proportional valve 13, and each flow detector 14 detects the gas flowing through a proportional valve 13. The number of control panels 12, proportional valves 13, and flow detectors 14 can be set as needed. The gas flowing through each proportional valve 13 can be different, thus allowing different gases to be introduced into the microbial culture system simultaneously. This facilitates the addition of multiple gases.

[0025] like Figures 1 to 4 As shown, there are three control panels 12, proportional valves 13, and flow detectors 14. One auxiliary air intake channel 111 is connected to the oxygen supply structure, one auxiliary air intake channel 111 is connected to the nitrogen supply structure, and one auxiliary air intake channel 111 is connected to the carbon dioxide supply structure. Oxygen, nitrogen, and carbon dioxide are commonly used gases for microorganisms. These three gases can be supplied to the microbial culture system separately or selectively.

[0026] like Figures 1 to 4 As shown, the air outlet of the connection channel 113 is connected to a first quick connector 15. The first quick connector 15 facilitates connection to a microbial culture system.

[0027] like Figures 1 to 4As shown, the gas supply structure of the microbial culture system also includes a main manifold 20. There are multiple gas supply modules 10. The main manifold 20 is provided with several main air intake channels 21. The number of main air intake channels 21 is equal to the number of auxiliary air intake channels 111. The auxiliary air intake channel 111 at the corresponding position in each gas supply module 10 is connected to the main air intake channel 21.

[0028] like Figures 1 to 4 As shown, the number of main air intake channels 21 is equal to the number of auxiliary air intake channels 111 in one air supply module 10. It is small in size, integrated, and can supply air to multiple microbial systems.

[0029] like Figures 1 to 4 As shown, in this invention, there are three main air intake channels 21, multiple air supply modules 10, and three auxiliary air intake channels 111 within each air supply module 10.

[0030] like Figures 1 to 4 As shown, each of the main air intake channels 21 is connected to a second quick connector 22 at its air intake end. The second quick connector 22 facilitates connection to the air supply structure.

[0031] The above are specific embodiments of this utility model.
