摘要： A sampling probe, an automatic sampling device, and a container detection system are provided. The sampling probe includes: a mounting base; a housing mounted on the mounting base, a first accommodation chamber having an opening being defined in the housing, and an exhaust hole in communication with the first accommodation chamber and outside of the housing being formed in the housing; a coupling portion formed on an outer edge of the opening of the first accommodation chamber and formed to be hermetically coupled with an air outlet of a container; and a suction device mounted on the housing and configured to suck gas in the container into the first accommodation chamber through the air outlet. The sampling probe may collect the odor of toxic and harmful gases/hazardous chemicals inside the container at the air outlet of the container, without destroying the overall structure of the container.
