Abstract: A detection assembly, including a first liquid path, a second liquid path, a liquid inlet, a liquid outlet, and a valve assembly. An end of the first liquid path is in communication with the liquid inlet, and another end is in communication with the liquid outlet; an end of the second liquid path is in communication with the liquid inlet, and another end is in communication with the liquid outlet. The valve assembly can be switched between a first turn-on state and a second turn-on state. In the first turn-on state, a first external liquid flows into the first liquid path from the liquid inlet and out of the first liquid path from the liquid outlet. In the second turn-on state, a second external liquid flows into the second liquid path from the liquid inlet and out of the second liquid path from the liquid outlet.
