The present utility model relates to the field of manufacture of sanitary wares, and provides a toilet. The toilet includes a seat body with a sewage accommodating bowl, and a cistern. The inside of the cistern is provided with a fill valve, a first ring flushing pipeline, a first water inlet end of the first ring flushing pipeline is selectively in fluid communication with the fill valve, a first water outlet end of the first ring flushing pipeline is in fluid communication with a ring flushing port opening, and the first ring flushing pipeline includes a first jet flow increasing structure; a second bottom flushing pipeline, a second water inlet end of the second bottom flushing pipeline is selectively in fluid communication with the fill valve, and the second bottom flushing pipeline includes a second jet flow increasing structure; and a pipeline switching mechanism, being able to automatically switch the fluid communication between the first ring flushing pipeline and the fill valve or between the second bottom flushing pipeline and the fill valve in response to a water level in the cistern. By using such toilet, the sewage accommodating bowl can be more cleanly and thoroughly flushed with the same water consumption, or a low-profile cistern design can be realized under the same water pressure requirement.

A water supply mechanism includes a switching part that executes switching between water supply and water shut-off, a manual operation valve on the switching part that is capable of a manual operation thereof, and a pushing member that pushes the manual operation valve to provide a valve-closed state. The manual operation valve is pulled in a direction opposite to a pushing direction of the pushing member to provide a valve-opened state. The manual operation valve includes a plunger, an external cylinder member that encloses the plunger, a first engaging point in the external cylinder member, and a fixation part in the external cylinder member that fixes the plunger in the valve-closed state or the valve-opened state. The plunger moves beyond the first engaging point as the manual operation valve is pulled, and is fixed in the valve-opened state as a pull of the manual operation valve is released.

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.

The present disclosure provides a water supply assembly of a toilet comprising a water input pipe, a water tank, a water suction pump and a water output pipe; wherein the water input pipe is connected to the water tank; clean water enters the water tank through the water input pipe; the water tank is connected to the water suction pump connected to the water output pipe; the water suction pump pumps the clean water inside the water tank into the water output pipe; the water tank comprises a main water tank portion, an auxiliary water tank portion, and a water equalizing pipe connecting between and through the main water tank and the auxiliary water tank. The present disclosure provides a flushing assembly, a water suction assembly, and a check valve for use in the toilet. The present disclosure provides a method, device, and storage for controlling toilet water consumption.

A siphon valve assembly, the assembly comprising a tubular core; a head coupled to and surrounding a top of the core; and a fluid spray initiator coupled to the head; wherein a lower end of the head defines a siphon valve inlet, a lower end of the tubular core defines a siphon valve outlet, an upper end of the tubular core comprises a weir, and the spray initiator is configured to discharge a fluid into the core to induce a siphon flow of a surrounding fluid through the siphon valve inlet, over the weir, and out the siphon valve outlet.

Hydraulic devices used to control timing, direction, and velocity of fluid flow are disclosed. The hydraulic device includes a flush valve. The flush valve includes one or more venturi that assist in moving the fluid through flush valve. A manifold includes a housing defining a piston cavity and a piston. The piston is moveable within the piston cavity by a piston actuator between a first position and a second position. A manifold inlet defined by the housing is configured to receive a first fluid from a supply line and is in fluid communication with the piston cavity. A manifold outlet is defined by the housing and is in fluid communication with the piston cavity in. In the first position, the piston prevents fluid communication between the manifold inlet and the manifold outlet through the piston cavity. In the second position, the manifold inlet is in fluid communication with the manifold outlet such that the first fluid can flow from the supply line to the manifold outlet through the piston cavity.

A toilet includes a bowl with a sump and a trapway connecting the sump to an outlet of the toilet. The trapway has a zeta shape and is configured to induce a siphon which provides pressure to suction waste water from the bowl during a flush cycle. A trapway supply conduit is connected to the trapway in a tangential orientation to an upleg region of the trapway. The trapway supply conduit supplies water to the trapway, which follows a contour of the inner surface of the trapway supply conduit and continues in the same direction into the upleg region of the trapway by relying on a fluid flow to follow the curve of a convex surface placed proximate to the flow.

The flush water tank apparatus of the present invention includes: a clutch mechanism 30 coupling the discharge valve 12 and the discharge valve hydraulic drive unit 14 to pull up the discharge valve, and being disconnected at a predetermined timing to cause the discharge valve to descend; flush water amount selection device capable of selecting from a first and a second amounts of flush water; a float device 26 including a float and a holding mechanism switchable between a holding and a non-holding states in conjunction with movement of the float; and a timing control mechanism controlling a timing of a drain port 10a being blocked; and, when the second amount is selected, causes the second amount of flush water to be discharged by switching the holding mechanism to the non-holding state before a water level in a storage tank drops to a predetermined water level.

A water turbine and electric motor hybrid power suction type water-saving toilet, with toilet main body comprising a hollow frame, a hollow frame water inlet, a basin bottom water injection hole and an S-shaped bend, wherein the hollow frame is located on upper part of the toilet with water injection holes distributed along the periphery towards inner side of the toilet; the hollow frame water inlet is formed in rear part of the toilet; the basin bottom water injection hole is formed in lower part of the toilet and communicates with the hollow frame water inlet through a pipe cavity attached to outer wall of the toilet; and a basin bottom water injection valve is arranged at the opening of the basin bottom water injection hole leading to the S-shaped bend and controls connection/disconnection of basin bottom water injection hole and S-shaped bend inlet section with water pumping process synchronously.

A sanitary fixture having a body with an upwardly open pan region. A water chamber is provided in the region of the upper rim of the pan region and, when viewed horizontally, protrudes into the pan region. At least one flushing opening oriented downwardly into the pan region is provided on the chamber side. At least one connecting portion is provided in the rear region of the body for connecting a flushing water supply pipe for supplying flushing water into the water chamber, the flushing water flowing therefrom into the pan region via the at least one flushing opening on the chamber side. The water chamber extends only in a rear rim region. At least one second flushing opening is provided oriented to the front to permit a tangential flushing of the water into the pan region and is able to be supplied with flushing water.
