[0002] With the development of society and the increase in population, the contradiction between the growth of water resource demand and water resource shortage in my country is becoming increasingly severe. Existing research shows that rainwater on building roofs is relatively clean and can be directly used after simple treatment. The main principle is to collect rainwater on the top of the building, and then reuse it after simple sedimentation and filtration. The treated rainwater can be used as grey water, such as flushing toilets, watering green spaces, spraying roads or recharging underground, etc., and for areas with relatively scarce water resources, it can also be used as a water resource to alleviate water shortages. However, there are still some problems to be solved in the actual application of rainwater utilization devices for buildings. The main problem is that the existing rainwater collection efficiency is low, and it has little effect on light and moderate rain weather. In addition, the rainwater utilization device needs to filter impurities in the rainwater, but the impurities are not convenient to clean, which affects the subsequent use.

[0003] Therefore, the applicant proposes a rainwater utilization device for buildings to solve the above problems. Utility Model Content
