A sampling assembly, including a sampling needle, a first pipeline, a second pipeline, a driving member, a first switching member, and a second switching member, is disclosed. The first pipeline is connected between the sampling needle and the first switching member. The second pipeline is connected between the first switching member and the driving member. The first switching member is used for connecting or disconnecting the first pipeline and the second pipeline. The second pipeline is connected, by means of the second switching member, to a negative pressure source. The sampling time of the sampling assembly of the present disclosure is relatively short. The present disclosure further discloses a sample analyzer and a sampling method.
