An actuating device for a sanitary fitting comprising a housing (2) having a front side (13) and a rear side (14) and also a detection sensor (3) having a transmitter (4) and a receiver (5) for detecting a user, wherein the detection sensor (3) emits waves via the transmitter (4) and receives them via the receiver (5). The detection sensor (3) is arranged in a cavity (6) that has a radiating region (7a), which is transparent to said waves, in the direction of said waves; and wherein the housing (2) is designed such that it is installable having a gap (7b) in relation to a predefined installation plane (ME) on the structure side, which gap (7b) is located in relation to said radiating region (7a) such that the emitted waves and also the waves to be received are guided through the gap (7b).

The utility model discloses a light-emitting rotary knob. The light-emitting rotary knob comprises a rotary knob body, a connecting base and a PCB, wherein a plurality of LED light-emitting bodies are mounted on the PCB, a connecting concave hole is formed in one end of the connecting base, the rotary knob body is provided with a concave cavity and connected with the connecting base in a sleeving mode through the other end of the connecting base by means of the concave cavity, the PCB is mounted on the connecting base, and the multiple LED light-emitting bodies guide out light through the rotary knob body. Preferably, the connecting base comprises a cylindrical body, a protruding part extends out from the middle of one end of the cylindrical body, the connecting concave hole extends into the cylindrical body from the end face of the protruding part, a through hole is formed in the middle of the PCB, the protruding part is sleeved with the PCB through the middle through hole, the multiple LED light-emitting bodies are distributed around the through hole, and the cylindrical body is located in the concave cavity. The light-emitting rotary knob of the utility model has a good prompt effect, correct operation can be ensured, and the grade of a flushing toilet cover can be improved easily.

A flushometer system includes a valve body having an inlet, an outlet, and an actuation opening, a main valve seat assembly disposed in the valve body, a piston assembly slidably disposed within the valve body and configured for sealing the main valve seat assembly and moving to permit liquid to flow through the main valve seat assembly, and an actuation module engaged with the valve body. A relief chamber is defined between the actuation module and the piston assembly, and the actuation module is configured to vent the relief chamber upon actuation. The actuation module includes first and second plungers. The first plunger and the second plungers are moveable to vent the relief chamber, where the piston assembly moves to permit water to flow through the main valve seat assembly. Movement of the first plunger allows a larger flush volume to pass through the main valve seat assembly than movement of the second plunger.

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 manual override device for a flush assembly includes an override valve, an override chamber, and at least one input device. The override chamber includes a first fluid connection to a first side of a piston in a flush valve assembly and a second fluid connection to a second side of the piston in the flush valve assembly. The input device is coupled to the override valve and configured to initiate evacuation of fluid from the first side of the piston when the input device is actuated to begin a flush cycle in the flush valve assembly by way of movement of the piston.

A panel structure for a hidden water tank includes: a panel mounting frame configured to be connected to a water tank body; a panel body disposed on an outer side of the panel mounting frame and configured to be opened and closed relative to the panel mounting frame; and a hinge configured to connect a first end of the panel body to the panel mounting frame. A second end of the panel body is connected to the panel mounting frame.

A toilet pan is provided with a water replenishing device for flush rim with silence function. The water replenishing device has independent drainage from the drainage of the cisterns. The water replenishing device includes a water storage box with a water inlet on top side and a drainage outlet on bottom side. The drainage outlet is connected to the waterway for 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 back flow 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 toilet makes less noise by eliminating water inlet noise.
