The invention provides an in-cabin emergency pressure suit urine leading-out system, which comprises a wearable urine collector, a four-way reversing valve and a urine container, and is characterizedin that the wearable urine collector is arranged in a pressure suit and is connected with a human body; the wearable urine collector is communicated with the pressure suit through a first pipeline andconnected to the four-way reversing valve through a second pipeline, and the four-way reversing valve is provided with four ports. Two ends of the urine container are respectively connected with a third pipeline and a fourth pipeline, and the third pipeline and the fourth pipeline are respectively connected to the four-way reversing valve; one port of the four-way reversing valve is connected with one end of a fifth pipeline, and the other end of the fifth pipeline is connected to a urine outlet in the cabin wall of a spacecraft; an elastic separation membrane is arranged in the urine container, and a first cavity and a second cavity are formed in the positions, corresponding to the two sides of the elastic separation membrane, in the urine container respectively. The system has the advantages that urine in the urine container is discharged out of the spacecraft through pressure difference, safety and reliability are achieved, the structure is simple, and the requirement for long-termlife support of astronauts in the lunar landing task pressure loss environment can be met.
