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 toilet includes a bowl portion, a rim portion, and a reservoir. The bowl portion defines a bowl cavity that is in fluid connection with a trapway. The bowl cavity is configured to hold a volume of water to provide a water seal for the trapway. The rim portion extends about an upper portion of the bowl portion. The rim portion defines an internal rim cavity that extends about an upper portion of the rim portion and a plurality of apertures that extend from the internal rim cavity and through a sidewall of the rim portion to direct water from the internal rim cavity to the bowl cavity. The reservoir is in fluid communication with the internal rim cavity and the bowl cavity and configured to receive a supply of pressurized water from a water source and direct at least a portion of the pressurized water to the internal rim cavity.

A tank assembly for a pressure-assist toilet includes a flush assembly having an outer chamber and an inner chamber disposed in the outer chamber. The flush assembly further includes a flush valve disposed in the inner chamber, and a pilot valve disposed in the inner chamber and extending through the flush valve. The tank assembly further includes an actuator engaging the pilot valve and configured to hold the pilot valve at each of a first height, a second height offset a first distance from the first height, and a third height offset a second distance from the first height greater than a first distance.

A flush actuator for engaging a flush valve. The flush actuator provides a mechanism assembly for automatically flushing the flush valve. A sensor provides a presence detection to trigger the automatic flushing. Redundant manual activation is provided.

A flush valve for a toilet, the flush valve including a main valve unit for causing a main valve body to reciprocate between a closed position and an open position in response to pressure inside a back pressure chamber communicating with a primary side flow path thereby opening and closing a flow path between the primary side flow path and the secondary side flow path. The flush valve further including a sub-valve unit having a sub-valve body for opening and closing a bypass flow path connecting the back pressure chamber and the secondary side flow path. The flush valve further including a generating unit disposed on the downstream side of the main valve unit and serving as flow path resistance on the secondary side flow path. Wherein the bypass flow path is connected to the secondary side flow path downstream of the generating unit.
