A recently granted patent (Publication Number: US11871880B2) discloses a solid-liquid separation anti-soiling toilet designed to efficiently process excreta while minimizing soiling. The innovative toilet system includes a processor connected to a solid container, a liquid reservoir, and an exhaust device. The processor features a housing with a clamping device and a drying device inside. After use, excreta enters the clamping device where the liquid is separated and directed to the liquid reservoir, while the solid waste is pressed and dried into a sheet before entering the solid container. The drying device generates hot air flow to facilitate the drying process, which is then exhausted through the connected exhaust device. The clamping device is equipped with a rotary mechanism and a fixed mechanism to effectively press the solid waste for optimal separation.

Furthermore, the patent details additional features of the solid-liquid separation anti-soiling toilet, including a push device for transferring the dried and pressed waste into the solid container, a cover plate to seal the processor during operation, and a drying device comprising an air supply and heating device. The design also incorporates liquid discharging holes, a receptacle for collecting liquid waste, and an exhaust system with an induced draft fan and exhaust pipe. The mounting method involves connecting the processor to the solid container through a limit stop and ensuring communication between the receptacle and the liquid reservoir via a liquid drain pipe. With its innovative design and efficient waste separation capabilities, this patented toilet system aims to enhance sanitation practices and reduce soiling in toilet facilities.
