The invention relates to an inlet valve arrangement (10) for a toilet cistern which is configured to regulate and control the flow of water. The arrangement includes a connector (12) which is connectable to an inlet water supply, a valve body (14) which is connected to the connector (12) and defines a valve inlet (16); and a sealing mechanism which includes a sealing member (18) which is displaceable relative to the valve body (14) between an open position in which water is permitted to pass through the valve inlet (16) and a closed position in which the sealing member (18) seals off the valve inlet (16) in order to prevent water from passing through the valve inlet (16). An over-centre linkage (20) is connected to the sealing member (18), movable in over-centre fashion between a first position in which the sealing member (18) is in its open position and a second position in which the sealing member (18) is in its closed position.

Disclosed in the present utility model is a connecting rod drive mechanism for a water discharge valve, comprising a base, a first stage connecting rod, and a last stage connecting rod, the first stage connecting rod and the last stage connecting rod are movably arranged on the base, a drive part, a turning part, and a transmission part are provided on the last stage connecting rod, the drive part cooperates in transmission with an initiation assembly of the water discharge valve, the transmission part cooperates in transmission with the first stage connecting rod, the turning part forms a relative turning connection with the base, the turning part is located between the drive part and the transmission part, or the transmission part is located between the drive part and the turning part, and the first stage connecting rod is driven so as to impel the last stage connecting rod, causing a drive part of the last stage connecting rod to drive the initiation assembly of the water discharge valve to be opened and discharge water. The connecting rod drive mechanism of the present utility model is able to amplify drive travel, can allow for more flexible positioning of a drive mechanism, and there is relatively low eccentric force during the process of driving, which is beneficial for extending assembly life.

A gear driven trip lever for a toilet comprises a handle, a handle stop and a torsion spring disposed outside the tank. Inside the tank is a gear driven trip lever subassembly comprising a home position rack that is secured to a mounting plate and a spring-loaded clutch cam. The end of the flush lever nearest the gear driven trip lever subassembly is configured as a geared structure that meshes with gears disposed on a home position rack. When a user pushes the flush handle, the home position rack lifts the geared flush lever. The clutch cam contacts and slides on the home position rack as it moves downwardly. When the flush handle is fully depressed downwardly, the clutch cam releases the home position rack which returns to its home position via a compression spring and the geared flush lever is returned to its home position.

Toilet assemblies having various embodiments of a cleaning system are described herein which include a toilet assembly and a cleaning system. The toilet assembly has a toilet bowl, a toilet tank, a flush valve, a rim inlet port and a rim flow path (which may be an isolated rim path) extending from an outlet of the flush valve to the rim inlet port. The cleaning system has a reservoir for holding a liquid cleaning agent having an outlet port in fluid communication with the interior space of the reservoir body; a housing to receive the reservoir, a supply conduit in fluid communication with the interior of the reservoir; a flow control device capable of controlling flow through the supply conduit; and a control system activatable by an actuator feature, wherein upon activation of the actuator feature, the control system is adapted to initiate a clean cycle by: operating the flow control device for a first period of time sufficient to deliver a dose of a liquid cleaning agent from the supply conduit to an interior space of the flush valve in a closed position, the flush valve configured for delivery of fluid to the rim inlet port, and operating the flush valve to open the flush valve to introduce flush water to carry the dose of a liquid cleaning agent through the rim inlet port into the toilet bowl.
