Detection chip assembly tool, liquid injection apparatus and method, electronic device, and medium

A liquid injection apparatus for a detection chip, wherein, the liquid injection apparatus comprises a liquid injection assembly, a vacuumizing assembly, a control module, and the detection chip assembly tool;

• the detection chip assembly tool comprises:
• a base mounted on a detection chip, the base is provided with a reaction cavity covering the detection chip and a fluid channel communicated with the reaction cavity, and is further provided with a inlet groove structure communicated with the fluid channel and having a buffer solution injected;
• wherein, when the detection chip is filled with the buffer solution, the vacuumizing assembly is started to discharge air in the detection chip assembly tool, in response to the vacuumizing assembly vacuumizing, pressure relief is performed, and the buffer solution in the inlet groove structure flows into the reaction cavity along the fluid channel under the action of negative pressure so as to fill the detection chip;
• the detection chip assembly tool is mounted on the vacuumizing assembly, and the liquid injection assembly is used to inject buffer solution into the inlet groove structure;
• the control module is configured to start the vacuumizing assembly to discharge air in the detection chip assembly tool when filling the detection chip with buffer solution;
• the control module is also configured to respond to detect out a preset vacuum condition being established in the detection chip assembly tool, then start the liquid injection assembly to inject the buffer solution into the inlet groove structure and control the vacuumizing assembly to release pressure, and the buffer solution in the inlet groove structure flows into the reaction cavity along the fluid channel under the action of negative pressure so as to fill the detection chip.
