A Toilet Flushing Apparatus Locking Nut System characterized by affixing a rigid rod to a securing nut that contains multiple rod receiving holes. The locking nut system maintains a secured position by means of resistance created when the rod contacts the toilet flushing apparatus's lifting arm, preventing rotational movement of the securing nut to less than 360 degrees. Multiple rod receiving holes within the body of the securing nut afford the ability to adjust the rod's positionto further reduce the securing nut's rotation travel to less than 360 degrees.

Provided is a system, method, and apparatus for preventing repeated use of a restroom appliance with visual feedback. The system includes a valve configured to control flow of a fluid by at least one valve operation, an actuator configured to request a use of the restroom appliance, at least one indicator configured to display at least three different visual states, and at least one controller in communication with the actuator, the valve, and the at least one indicator. The at least one controller is programmed or configured to control the at least one indicator to display a first visual state, receive a plurality of requests to operate the restroom appliance exceeding a maximum number of valve operations, perform a first valve operation in response to receiving a first request, and control the at least one indicator to display a second visual state in response to performing the first valve operation.

A toilet is provided with a water replenishing device for a flush rim with a silencing function. The water replenishing device has independent drainage from the drainage of the cistern. The water replenishing device includes a water storage box with a water inlet on a top side and a drainage outlet on a bottom side. The drainage outlet is connected to the waterway for the flush rim. A lid is installed in the water storage box to open or close the drainage outlet. The water storage box is provided with a water storage area. A backflow channel has one end connected to the water inlet and the other end extending into the water storage area below or equal to the highest level of the water storage area. Such toilets make less noise by eliminating water inlet noise.

A pneumatic valve control device includes an air cylinder. The air cylinder includes a first piston; an air outlet; and a locking and releasing mechanism configured to lock and release the first piston when the first piston is pushed up. The device also includes a hydraulic cylinder. The hydraulic cylinder includes a second piston; an air vent disposed on a first side of the second piston; and a liquid inlet and a liquid outlet disposed on a second side of the second piston. The device also includes a partition disposed between the hydraulic cylinder and the air cylinder; a partition channel disposed on the partition; a piston rod connected to the second piston and configured to pass through the partition channel; and a tappet valve connected to the piston rod and configured to leave the partition channel in response to an upward movement of the piston rod.

A control handle module includes a flush handle, a first lever and a second lever. The flush handle has an extension. The first lever is secured on the extension. The first lever includes a body section, a fixing portion and a pivot base. The pivot base has an arcuate periphery which is provided with a first stop rib and a second stop rib. The second lever has a first shank and a second shank. The second shank has a resting face and a pivot ear. The pivot ear is pivotally connected with the pivot base. The resting face rests on the first stop rib or the second stop rib.
