Description

Technical Field

[0001] The utility model relates to the technical field of green buildings, in particular to a rainwater collection and purification device for green buildings. Background Art

[0002] Green buildings are high-quality buildings that save resources, provide people with healthy and efficient use of space, and maximize the harmonious coexistence of man and nature. In order to save water resources during use, rainwater can be collected to a certain extent. The collected rainwater is used for irrigation of greenery, flushing toilets, etc., which can save water resources and greatly alleviate my country's water shortage problem.

[0003] In the process of collecting rainwater, the existing rainwater collection device adopts a filter to intercept impurities in the rainwater. However, the filter is generally fixed and cannot be disassembled. A large amount of impurities will remain after long-term use, which is easy to cause blockage, thereby affecting the filtration of rainwater and reducing the practicality of the rainwater collection and utilization device.
