Title:
ENERGY STORAGE DEVICE AND TOILET FLUSHING SYSTEM HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2021/196403
Kind Code:
A1
Abstract:
An energy storage device and a toilet flushing system having same. The energy storage device comprises: a body (10) having a water inlet (11), a water outlet (12), an energy storage cavity (13), an overflow channel (14) for communicating the water inlet (11) with the water outlet (12), and a main valve port (15) for communicating the energy storage cavity (13) with the water outlet (12); a main control valve (20) comprising a main valve core (21) working in conjunction with the main valve port (15); and an elastic energy storage assembly (30), movably provided in the energy storage cavity (13). When no water flows in the water inlet (11), the main valve core (21) closes the main valve port (15), and the overflow channel (14) is closed; when water flows in the water inlet (11), a water flow overcomes an elastic force of the elastic energy storage assembly (30) to flow into the energy storage cavity (13) and drives the elastic energy storage assembly (30) to move to a predetermined position, and the overflow channel (14) is opened, so that the side of the main valve core (21) facing away from the energy storage cavity (13) opens the main valve port (15) under the effect of a water pressure, and the water in the energy storage cavity (13) is discharged and flows out together with the water in the water inlet. The apparatus performs energy storage and pressurization on the water flow, and has a simple structure and reliable functions.
