[0033] Embodiment 1

[0034] like Figure 1-Figure 3 As shown, a roof structure proposed by the utility model includes a roof panel 1, a collection box 2, a water retaining assembly, a filter screen 3, and a scraper assembly arranged on the collection box 2 for removing solid matter;

[0035] The collecting box 2 is arranged at the lowest end of the roof panel 1, and a water inlet end and a material outlet end are respectively arranged on both sides of the collecting box 2; a water retaining assembly is arranged in the collecting box 2; a filter screen 3 is arranged between the water retaining assembly and the collecting box 2, and the filter screen 3 is close to the water inlet end. The collecting box 2 and the filter screen 3 are used in coordination to collect and filter rainwater, and can provide additional water sources in dry seasons or areas with water shortages; the collected rainwater can be used for non-drinking water purposes such as irrigating vegetation, washing vehicles, and flushing toilets, thereby reducing dependence on groundwater or tap water.
