Water-Saving Toilet System Based on Mechanically Driven Piston and Smart Nozzle Spray

Description This invention introduces a water-saving toilet system designed to significantly reduce water consumption during usage. Unlike conventional toilets, which use large volumes of water per flush, this system minimizes usage to as little as 200–300 ml during lid operations and 500–1000 ml per flush, depending on the type of waste. The mechanism is based on a lid-connected mechanical and electronic system. When the lid is opened, it activates a small spray mechanism that moistens the toilet bowl and waste cylinder to prevent sticking. Simultaneously, a piston system prepares to assist with waste transfer. When the lid is closed, the piston with a cleaning rubber scrapes waste from the inner surface and guides it toward the sewer pipe. An integrated electronic valve, controlled by flush-type buttons (for small or large waste), manages the release of an additional water jet to clean the system and complete the waste removal. The design includes a sealed cylinder system that blocks odors and contaminated air from exiting the sewer line. The device operates without dependence on external power due to a rechargeable battery system and uses a dynamo mechanism triggered during lid movement to assist in airflow control. This ensures energy efficiency and allows continued use even during power outages. This innovative toilet is ideal for homes, public restrooms, and areas where water conservation is critical. It contributes to environmental sustainability by significantly lowering water usage without compromising hygiene.
