When animal experiments are carried out, excrement of animals is often required to be detected and analyzed, and the separation detection data of excrement and urine is particularly critical. However, the existing equipment often has many defects: cross infection, loss in the process of collecting excrement, mixed sundries such as food residues, animal stress reaction caused by poor feeding environment and the like all cause inaccurate experimental data and loss of experimental significance.
