A toilet flushing assembly includes at least a spiral trapway and a drive mechanism. The spiral trapway includes an upstream portion coupled to a toilet bowl, a curved portion, and a downstream portion coupled to a waste outlet. The drive mechanism is coupled to the spiral trapway and configured to rotate the spiral trapway from a first orientation to a second orientation. The first orientation evacuates contents from the toilet bowl and the second orientation advances the contents from the spiral trapway to the waste outlet.

The automated toilet comprises a toilet with a motorized pump in line with the drain pipe, a sensor, a control box, and a flush valve actuator. The sensor detects the presence of a user in front of the toilet and notifies the control box. When a user arrives, the control box starts the pump to draw air through the rim and into the sewer line, which removes odors while the toilet is being used. When the user leaves, the control box activates the flush valve actuator, causing the toilet to flush. The control box may run the pump for a predetermined time interval so that the pump may assist in emptying the bowl. When the bowl has emptied, the pump may continue to draw odors from the bowl until the control box shuts the pump off.

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

In a tri-flush toilet, three operational flush modes may be provided to enable water conservation. The toilet may include a third mode operating a peristaltic pump to reduce the water consumption per flush. The peristaltic pump is operably connected to evacuate fluids and/or solids form the toilet bowl.

A drain valve for low-level water tank flushing includes a drain valve body, a low-level washing ring flushing device and a switch assembly. The switch assembly includes a switch element and a switch sheet. The switch element is connected to the switch sheet by using a lifting rod. When the switch element opens a sealing assembly of the drain valve body under the action of an external force, the switch sheet changes a channel between a water inlet and a water outlet from a small opening state to a big opening state.

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel. The bowl has a closed jet pathway to maintain the jet channel in a primed state with fluid from the jet flush valve assembly to prevent air from entering the closed jet pathway. Flush valves may have back-flow preventer mechanisms and/or at least partly flexible valve covers, including specific valve cover structures. Flush activation assemblies may have a flush activation bar connected to the pivot rod and/or an adjustable flush connector located between the pivot rod and the flush activation bar. A kit providing one or more flush activation elements is included. The kit elements may be usable with the toilet systems and methods described.

A siphonic flush toilet system and method of priming the same having a toilet bowl assembly comprising at least one jet flush valve assembly and at least one rim valve; and bowl having a rim and a jet defining at least one jet channel, the at least one jet channel having an inlet port and a jet outlet port configured for discharging fluid to a sump area, wherein the sump area is in fluid communication with a trapway. The bowl has a closed jet pathway including the jet channel and extending from the jet flush valve assembly outlet to the jet channel outlet port to maintain the jet channel in a primed state with fluid from the jet flush valve assembly so as to assist in preventing air from entering the closed jet pathway. Flush valves are also disclosed having back-flow preventer mechanisms and/or at least partly flexible valve covers for use with the toilet systems and methods herein

An improved flapper valve has an elastomeric surrounding flapper valve top. A separate inverted dome-like structure, or cone, which is the ballast, is included for insertion into the flapper valve top. The improved flapper valve further includes a ring-like upper structure and a cap-like bottom structure. The ring-like upper vent band structure rotates about the cone relative to an air outlet aperture defined in the cone to control air flow from the cone. The bottom cap-like adjuster structure also rotates about the bottom of the cone to control water flow into the cone, also via apertures in both structures. Used together, the upper and bottom structures can minimize water consumption by the toilet. Further, the adjuster structure includes means for discretely changing settings with indicia to indicate to the user what the current setting is and means for maintaining that setting as may be desired or required.

The utility model discloses a light-emitting rotary knob. The light-emitting rotary knob comprises a rotary knob body, a connecting base and a PCB, wherein a plurality of LED light-emitting bodies are mounted on the PCB, a connecting concave hole is formed in one end of the connecting base, the rotary knob body is provided with a concave cavity and connected with the connecting base in a sleeving mode through the other end of the connecting base by means of the concave cavity, the PCB is mounted on the connecting base, and the multiple LED light-emitting bodies guide out light through the rotary knob body. Preferably, the connecting base comprises a cylindrical body, a protruding part extends out from the middle of one end of the cylindrical body, the connecting concave hole extends into the cylindrical body from the end face of the protruding part, a through hole is formed in the middle of the PCB, the protruding part is sleeved with the PCB through the middle through hole, the multiple LED light-emitting bodies are distributed around the through hole, and the cylindrical body is located in the concave cavity. The light-emitting rotary knob of the utility model has a good prompt effect, correct operation can be ensured, and the grade of a flushing toilet cover can be improved easily.
