In conclusion, the beneficial effects of the invention are as follows: when people relieve the bowels greatly, the cushion 20 drives the middle part of the hose 62 to vertically move upwards from a concave state to a convex state through a series of transmission, water reserved in the hose 62 enters the drainage channel A4 and the bottom of the urinal 3 and reaches a certain liquid level height in the urinal 3, and excrement falling into the urinal 3 is submerged by water while the sewer and the toilet room are isolated and deodorized, so that the effect of isolating and deodorizing the excrement and the toilet room is achieved, and people can go to the toilet more comfortably. After people have a big defecate and wash the urinal 3, the cushion 20 drives the middle part of the hose 62 to vertically move downwards from an upper convex state to a lower concave state through a series of transmissions. Meanwhile, the supporting sleeve 61 drives the middle of the hose 62 to swing at a certain angle, so that the middle of the hose 62 is lower, the downward sinking degree of the hose 62 is ensured to meet the requirement, the amplitude of the vertical downward movement of the middle of the hose 62 driven by the slider A53 is smaller, the space of the transmission cavity 5 is saved, and the internal structure of the equipment is more compact. The water that persists in urinal 3 bottom and drain A4 all flows to in the hose 62 of recessed state to guarantee that the water of persisting in hose 62 completely guarantees that urinal 3 bottom does not keep the water of depositing when isolated deodorant with sewer and bathroom indoor, thereby has avoided leading to the emergence of aquatic deposit attached discoloration phenomenon because of long-time retention water seal in urinal 3, improves sitting posture closestool's sanitary environment, reduces sitting posture closestool's cleaning work volume.

The locking of the ring sleeve A16 by the limiting rod 27 in the invention ensures that the cushion 20 does not automatically swing upwards under the reset action of the scroll spring A25 when the buttocks are lifted away from the cushion 20, thereby causing inconvenience to the movement of people who finish toilet.
