Patent number: 11832771Abstract: A self-mechanical-cleaning toilet system with water-splash cleaning options provides a more sanitary and comfortable bathroom experience with minimum water usage. The system includes a receiving trough, a removal scraper, a guide bar, a back door, a first translation mechanism, a second translation mechanism, and a controller. The receiving trough collects the excrement, while the removal scraper moves the excrement out. The guide bar controls the movement of the removal scraper along the receiving trough. The back door separates the receiving trough from an excrement storage compartment/sewer system. The first translation mechanism moves the removal scraper, while the second translation mechanism moves the back door as necessary. The controller monitors and controls the cycles of the operation of the first translation mechanism and the second translation mechanism. The water-splash cleaning options dispense specified amounts of fluids for cleaning and sanitation purposes.Type: GrantFiled: February 16, 2022Date of Patent: December 5, 2023Inventors: Baozhong Li, Xiao Li
