智能公厕三维模型

A detailed 3D visualization of a smart public toilet system, showing rainwater management where rainwater is collected from the toilet roof, stored in tanks, and reused for flushing and cleaning. Inside the toilet, an automatic disinfectant spray system activates after each use. Outside, an LED cleanliness indicator displays percentage levels: 100 to 70 percent in green (clean), 69 to 50 percent in yellow (moderate), and 49 to 0 percent in red (dirty). When the LED shows red, an automatic alert notification is sent to management system or computer, and a cleaner arrives to clean the toilet. Show a person using the toilet, sensors detecting usage, pipes, water tank, modern design, clean engineering diagram style, labeled components, realistic lighting, educational 3D model.
