A waste material discharging device in a sanitary appliance comprising a seat (1) and a vessel, to which the seat is pivotally connected, having an opening for conveying and collecting the waste material. The device comprises a roller (4) rotatable in only one direction about its axis, integral to the seat (1) and placed therebelow at said opening, scraping means (5) stationarily arranged parallel to the roller (4) and substantially in contact to the surface of said roller, driving means (11), operable by a user, for driving unidirectional and intermittent, axial angular displacements to the roller, and means for dispensing (15, 18) a cleansing and sanitizing liquid, directed toward the surface of the roller (4) and driven by the same roller rotation driving means (11).

Provided is a dual-control flushing device, including: a body including a water tank; a valve assembly including a valve body and a valve stem configured to control opening or closing of a flushing port, wherein a transmission part extends from an end of the valve stem; a first flushing mechanism including a pressing assembly and a transmission assembly; a second flushing mechanism including a foot-controlled assembly, a lifting block and a traction rope, wherein the lifting block includes a lifting part, the traction rope includes a first control end connected to the foot-controlled assembly and a second control end connected to the lifting block, the foot-controlled assembly is configured to squeeze or release the first control end, so that the first control end and the second control end move and drive the lifting block and the valve stem to lift synchronously. The dual-control flushing device is convenient for users.

A hydraulic propulsion system for disposing of human waste. The system includes a toilet having a bowl, and a base below the bowl. The base is secured to the chassis of a vehicle, or to a remote sanitation facility. The system also comprises a hydraulic flushing mechanism associated with the toilet, and a fluid receiving chamber that receives water and human waste when the flushing mechanism is actuated. The human waste is directed through a sewage ejection pipe and into a black-water tank or a municipal sewer system. The human waste propulsion system further comprises a pneumatic line. The pneumatic line is in fluid communication with the fluid receiving chamber proximate the bowl. The pneumatic line receives compressed air which is delivered when the hydraulic flushing mechanism is actuated. Additionally, the human waste propulsion system has a controller.
