Title:
PRESSURE BAG DRAINAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/109182
Kind Code:
A1
Abstract:
Disclosed in the present invention is a pressure bag drainage system, comprising a pressure bag body and a drainage structure. The drainage structure comprises an accommodating cavity and a diaphragm. The accommodating cavity is provided with a water outlet, a water inlet, and a drainage pipe. The diaphragm is movably matched in the accommodating cavity to divide the accommodating cavity into a back pressure cavity and a drainage cavity, and is provided with a water replenishing hole communicated with the back pressure cavity and the drainage cavity. The water outlet is communicated with the back pressure cavity, and the water inlet and the drainage pipe are communicated with the drainage cavity. The pressure bag body is provided with a water storage cavity communicated with the water inlet. When the water storage cavity supplies water, water enters the drainage cavity and enters the back pressure cavity by means of the water replenishing hole, and the pressure of the back pressure cavity is increased. When the water outlet is open, the back pressure cavity discharges water to reduce the pressure, and the diaphragm is close to or far away from the drainage pipe along with the pressure change of the back pressure cavity so as to block or open the drainage pipe. The present invention simplifies the drainage mode of the pressure-type flushing system, it is guaranteed that the drainage structure is not affected by water supply pressure and flow change, and drainage is stable.
