Abstract: The present invention discloses a hydraulic energy storage mechanism, including a cylinder block, a cylinder body, a piston, a support, and a latch bolt component. In the present invention, a cylinder body, a piston, and a support structure being provided with a power slide block is used, and the tap water pressure is applied to push the piston to compress a spring and converted into elastic potential energy; the power slide block is driven by releasing the elastic potential energy to operate a suction drainage device of a water closet. The present invention has advantages of a small volume, large acting force, a simple structure, and reliable working, and effectively improves sewage drainage efficiency of the water closet.

Abstract: The present invention discloses a pumping drainage device for toilets, comprising a cylindrical shell, a cylinder cover, a cylinder sleeve, a piston and a lock tongue component, the shell is connected to the cylinder cover in the axial direction, the cylinder liner is sheathed in the cylinder cover, the piston is arranged in the cylinder liner, and the lock tongue component is arranged in the cylinder liner. The invention adopts two-stage movement of piston and cylinder liner, controlled by the lock tongue component, with the automatic reset function, greatly reducing the stroke of the piston under the status that the efficacy remains unchanged, with the advantages of compact structure, and easy operation, and good pumping effect.
