A smart suction seat for a nursing toilet stool, comprising: a housing (2) mounted on a base (1), the interior of the housing (2) being an inner cavity (4), a temperature and humidity sensor (44), a stool sensor (43), and a rinse nozzle (42) are respectively disposed within a cavity (41) of the inner cavity (4), a urine sensor (45) is disposed on the outer side of the cavity (41) lower portion, and a discharge port connected to an exterior negative pressure pipe is disposed vertically on the cavity (41) bottom portion； a washing device (6) and a ventilation device (5) internally connected to the cavity (41) are disposed on the outer side of the cavity (41) rear. The washing device (6) automatically adjusts the height of the nozzle (71), pressure and flow of the water, thus facilitating overall washing of a human buttock, and avoiding the disadvantage that a rinsing area cannot be adjusted due to a fixed current nozzle position. The temperature and humidity sensor (44) is internally disposed within the suction seat. When no stool or urine is generated, optimal skin comfort is obtained by adjusting an air parameter. The present invention has a compact structure, and maintains a high cleanliness even when the inner cavity is used for a long time； the present invention deploys an ergonomic structural design, thus facilitating optimal use effect.L'invention concerne un siège d'aspiration intelligent pour selles des toilettes de soins infirmiers, comprenant : un boîtier (2) monté sur une base (1), l'intérieur du boîtier (2) étant une cavité interne (4), un capteur de température et d'humidité (44), un capteur de selles (43) et une buse de rinçage (42) sont respectivement disposés à l'intérieur d'une cavité (41) de la cavité interne (4), un capteur d'urine (45) est disposé sur le côté externe d'une partie inférieure de la cavité (41), et un orifice d'évacuation relié à un tuyau de pression négative externe est disposé verticalement sur la partie inférieure de la cavité (41
