AI Technical Summary
Traditional flush toilets require more water when discharged from dirt due to symmetrical pot surfaces and large-sized sewage pipe design, which makes them need less cleaning capacity and waste water resources.
A flush-down toilet is designed, with the flush-down surface consisting of five asymmetrical areas, the size of the sewage pipe is reduced, and the waterway is designed to take three positions equally from top to bottom, gradually becoming smaller to increase the flush-down pressure.
By using less water, the dirt is collected in the sewage storage area and smoothly flushed out of the sewage discharge pipe inlet, improving the cleaning effect and greatly reducing the water consumption.
