Description

Technical Field

[0001] The utility model relates to the field of building decoration, in particular to a patio rainwater circulation purification system. Background Art

[0002] In traditional Chinese architecture, the space between houses or between houses and walls is called a patio. Usually, drainage channels need to be arranged on the ground to drain the rainwater falling from the patio.

[0003] However, in places where water resources are scarce, there is still the problem of inconvenience in getting water. Therefore, it is necessary to recycle rainwater to achieve the purpose of saving water.

In the rainy season, the rainwater retention layer can retain rainwater and purify and filter rainwater through plant roots, planting soil layers, sand filter layers, and rainwater collectors; when heavy rain or rainstorms occur, rapid overflow can be achieved through the overflow valve to prevent the rapid rainwater from scouring the vegetation. Obviously, this solution cannot solve the technical problem of patio rainwater collection.
