The present invention is an actuation apparatus that is adapted such that when a water level sensor senses water at above a predetermined level by means of a float of a float valve floating or rising to a predetermined level based on a corresponding increase in a water level, a diaphragm valve turns on or repositions such that water is allowed to flow from a pressurized water source to an actuator and the actuator actuates. The apparatus may be used in conjunction with a toilet having auxiliary discharge path and valve in preventing the toilet from overflowing.

A discharge valve operating device includes a first linking member and a second linking member, a rotary winding device, and an operation unit configured to rotationally operate the rotary winding device, wherein when the operation unit rotationally operates in a first direction, the operation unit is configured to perform toilet flushing in a full-flushing mode by pulling up the discharge valve by a first length by the rotary winding device winding the first linking member by the first length in the first direction, and when the operation unit rotationally operates in a second direction opposite to the first direction, the operation unit is configured to perform toilet flushing in a partial-flushing mode by pulling up the discharge valve by a second length by the rotary winding device winding the second linking member in the second direction by the second length which is the same as the first length.

Some embodiments include a fluid control system with an outlet valve assembly, an inlet valve assembly including a venturi inlet valve, and an actuator coupled to the inlet valve assembly. In some embodiments, the actuator can enable a user to control a flush volume of fluid control system. Some embodiments include a moveable float positioned in a chamber of the outlet valve assembly, where the chamber includes a variably-sized upper portion with a volume that is based at least in part on a variable position of the moveable float in the chamber. Some embodiments include a adjustable control valves coupled to an outer surface of the outlet valve assembly and the inlet valve assembly. Some embodiments also include a bellows positioned in and coupled to the variably-sized upper portion. In some embodiments, the bellows are fluidly coupled to the venturi inlet valve and at least one of the control valves.

Disclosed is a water tank drainage volume control structure comprising: a water tank body (1), having a first water storage chamber (11) and a second water storage chamber (12), the first water storage chamber (11) being provided with a first drainage channel, and the second water storage chamber (12) being provided with a second drainage channel; a drainage valve (2), used for controlling the opening/closing of the second drainage channel, the drainage valve (2) being provided with a full-drainage switch and a half-drainage switch for controlling the opening of the second drainage channel; and a water blocking member (3), moving with respect to the water tank body (1) under the control of the full-drainage switch or the half-drainage switch so as to control switching of the first drainage channel between open and closed states. The present invention uses a drainage valve to control drainage, can also achieve half drainage and full drainage of a water tank, and is simple in structure and reliable in function.

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.

An absorbent article is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core disposed between the topsheet and the backsheet, and a synthetic superabsorbent polymer derived from a first renewable resource via at least one intermediate compound, wherein said superabsorbent polymer exhibits a defined Saline Flow Conductivity value and Absorption Against Pressure value. Alternately, an absorbent article is disclosed having a synthetic polyolefin derived from a first renewable resource via at least one intermediate compound. The synthetic polyolefin exhibits defined performance characteristics making the polyolefin particularly useful in certain components of the absorbent article. Methods for making the aforementioned absorbent articles are also disclosed.

A flush valve has a relief valve including a stationary relief valve housing and an axially-translatable valve element. The axially-translatable valve element has an axial end that can be selectively translated to unseal an upper opening in a relief passageway through the stationary relief valve housing in order to permit fluid flow therethrough in order to initiate a flush cycle by the lifting of a diaphragm assembly. The axially-translatable valve element may include lead screw-like features which can be used to axially drive the axially-translatable valve element relative to the stationary relief valve housing to open or close the relief valve.
