in this embodiment, with reference to fig. 1, 3 and 4, a buffering inclined plane 1401 is disposed above the locking inclined plane 1402 on the locking slider 14 and faces the locking hook 13, and the buffering inclined plane 1401 is connected to the locking inclined plane 1402; the surface of the locking hook 13 facing the locking slider 14 is in engagement with the buffer ramp 1401 and the locking ramp 1402.

The included angle between the buffering inclined plane 1401 and the vertical plane is larger than that between the locking inclined plane 1402 and the vertical plane. The surface of the locking hook 13 opposite to the locking inclined surface 1402 is called a wedge surface 1302, the included angle of the locking inclined surface 1402 is small, locking is facilitated, the included angle of the buffering inclined surface 1401 is large, and when the locking hook 13 rotates, the lower end surface of the locking hook 13 abuts against the buffering inclined surface 1401 to rotate, so that buffering is achieved, and rigid impact is reduced;

in this embodiment, a pulley 19 is provided in the locking groove of the power slider 25 to reduce friction. The end of the bolt 12 is clamped into the lock groove and pressed on the roller 19, and when the movable sliding block 25 moves downwards under the thrust of the second elastic piece, the end of the bolt 12 slides out of the lock groove along the roller 19.

The working principle of the novel hydraulic energy storage mechanism provided by the embodiment is further described as follows:

the drainage button of the toilet bowl is manually pressed, the drainage valve connected to the drainage port 302 is opened, water in the piston cylinder is drained from the drainage port 302, the acting force of the water on the piston 4 disappears along with the drainage of the water in the piston cylinder, the piston 4 moves downwards in the piston cylinder under the action of the first spring 21, the piston rod 5 moves downwards in the piston cylinder hole in the sealing rod and the hole in the movable slider 25, the movable slider 25 is locked and is static at the moment, the pressing block 10 connected to the piston rod 5 starts to move downwards to be separated from the movable slider 25, and the linkage part 17 abutted to the pressing block 10 also moves downwards under the action of the fourth spring 23.

When the linkage 17 moves to reach the limit cap 18, the linkage 17 drives the limit cap 18, the connecting rod 15 and the locking slide 14 to move downwards against the resistance of the third spring 24.

When the link 17 moves down to the lower limit of travel position, the piston rod 5 drives the press block 10 to move to the position where the press block starts to be separated from the limit part of the link 17, the locking inclined plane 1402 moves down along the wedge surface 1302 until the end surface of the locking hook 13 abuts against the buffer inclined plane 1401, at this time, the locking inclined plane 1402 is separated from the locking hook 13, the link 17 stops moving, the lock tongue 12 is unlocked, under the action of the second spring 22, the movable slider 25 moves down, the pulley 19 abutting on the lock tongue 12 forces the lock tongue 12 to rotate towards the direction separated from the lock groove, namely towards the locking hook 13, the locking hook 13 engaged on the lock tongue 12 rotates towards the direction far away from the movable slider 25, namely towards the locking slider 14, the end surface of the locking hook 13 rotates along the direction of the buffer inclined plane 1401, and presses the locking slider 14, the connecting rod 15 and the limit cap 18 to continuously move down against the third spring 24. At this point, the latch 12 disengages from the pulley 19 and the movable slider 25 slides downwards in the bracket 9 under the action of the second spring 22. At this time, the movable slider 25 pulls the pull rope 26 of the toilet suction sewage device 27 to start working.

Because the device for opening the water inlet valve and the device for closing the water discharge valve are arranged at the stroke lower end limit position of the movable slide block 25, when the movable slide block 25 slides down to the stroke lower end limit position, the suction and sewage discharge device 27 finishes suction and sewage discharge work on the toilet, and meanwhile, the movable slide block 25 touches the water inlet opening device and the water discharge opening closing device, the water inlet valve is opened, the water discharge valve is closed, and tap water supplies water to the piston cylinder through the water inlet 301 of the piston cylinder.

With the opening of the water inlet valve, tap water supplies water to the piston cylinder through the water inlet 301 of the piston cylinder, and water acting on the surface of the piston 4 exerts pressure on the piston 4 to enable the piston 4 to overcome the resistance of the first spring 21 to move upwards, and meanwhile, the piston rod 5 and the pressing block 10 are driven to move upwards in the piston cylinder. The pressing block 10 drives the movable slider 25 to move upwards in the bracket 9 against the resistance of the second spring 22, and the linkage 17 moves upwards in the accommodating chute 20 along the connecting rod 15 against the resistance of the fourth spring 23.

When the pulley 19 on the movable sliding block 25 moves to the reset position of the bolt 12, the locking sliding block 14 and the connecting rod 15 and the limit cap 18 fixed on the locking sliding block 14 are pushed to move upwards due to the action of the third spring 24. At this time, the buffering inclined plane 1401 of the locking slide 14 abuts against the end surface of the locking hook 13 to force the locking hook 13 to rotate towards the direction of the movable slide 25, the hook surface 1301 of the locking hook 13 tightly grips the bolt 12, the bolt 12 rotates towards the direction of the movable slide 25, the bolt 12 is pushed into the locking groove of the movable slide 25 to clamp the pulley 19 for locking, the movable slide 25 is locked with the bracket 9, the piston 4 and the movable slide 25 are reset, and one working cycle is finished.
