摘要：
A vortex water flow cleaning system suitable for a urination and defecation nursing device, said system comprising: an excrement collection device (1), one end thereof being provided with an opening, another end being provided with an outlet, an excrement collection chamber being arranged between the opening and the outlet, the excrement collection chamber gradually shrinking along the direction from the opening to the outlet, a chamber wall of the excrement collection chamber being a smooth curved surface, an air inlet (16) and a water inlet (15) also being arranged on the excrement collection device, the air inlet and the water inlet being connected to the excrement collection chamber, the air inlet and the water inlet being arranged along the tangential direction of the chamber wall of the excrement collection chamber； a water supply system (2), connected to the water inlet； a negative pressure waste extraction system (3), connected to the outlet (12). The air inlet and the water inlet are arranged along the tangential direction of the excrement collection chamber in the excrement collection device, so that water and air entering from the tangential direction form a spiral vortex along the inner wall of the excrement collection chamber, so as to be able to fully clean the excrement collection chamber at the same time as washing away urine and excrement, without a high pressure water pump being required to drive a water source to enter.La présente invention concerne un système de nettoyage à écoulement d'eau tourbillonnaire approprié pour un dispositif infirmier de miction et de défécation, ledit système comprenant : un dispositif de collecte d'excréments (1) dont une extrémité est pourvue d'une ouverture, une autre extrémité étant pourvue d'un orifice de sortie, une chambre de collecte d'excréments étant disposée entre l'ouverture et la sortie, la chambre de collecte d'excréments se rétrécissant progressivement le long de la direction de l'ouverture vers la sorti
