The application provides a multifunctional testing device for simulating a real use scene of a paper diaper, and relates to the technical field of paper diaper performance detection. The multifunctional testing device comprises a base, a large arm connected to the base, a first rotating component arranged on the large arm, a small arm rotatably connected to the large arm through the first rotating component, a turning
flange connected to the small arm, a second rotating component arranged on the turning
flange, a baby posture
simulation model connected to the output end of the second rotating component, a liquid
simulation unit in communication with the baby posture
simulation model through a liquid pipeline, a
temperature control unit connected to the liquid simulation unit, a gas simulation unit arranged in the baby posture simulation model and used for outputting gas, a sensing unit arranged on the surface and / or inside of the baby posture simulation model, and a
control unit electrically connected to the first rotating component, the second rotating component, the liquid simulation unit, the
temperature control unit, the gas simulation unit and the sensing unit respectively.
