Vacuum closed pathogen nucleic acid detection cup

The utility model belongs to the technical field of pathogen inspection, and particularly relates to a vacuum closed pathogen nucleic acid detection cup, which comprises a detection device and a detection cup, when the vacuum closed pathogen nucleic acid detection cup is used, a reaction liquid tank is filled in a sampling cabin, the reaction cabin is in a vacuum environment, and the sampling cabin and the reaction cabin are in an isolated state; the reaction cabin is pushed to the direction of the sampling cabin, a channel is established between the sampling cabin and the reaction cabin through the through pipe, a sample is sucked into the reaction cabin through the negative pressure effect of the reaction cabin, the reaction cabin is reset after the sample flows into the reaction cabin, the reaction cabin is isolated from the sampling cabin again, and finally the infection condition is judged according to the reaction result. The detection sample is completely prevented from volatilizing into air, absolute
