摘要： A tank for a pressure-assist toilet flush system includes a base having an outlet configured for discharging water from the tank and a cover connected to the base, such that the cover and the base define a cavity to hold water to be discharged through the outlet. The tank may have a wall having a passage therethrough and extending upward from the bottom of the base and at least partially surrounding the outlet. The tank may also have a tray engaged with the base within the cavity and spaced upward from the bottom of the base. The tank may further have an air inducer assembly including a housing having a chamber and an outlet connected to the tank, a water inlet, and an air inlet, with a tube extending into the chamber and toward the outlet. The tube has a passage extending from the water inlet through the tube.

摘要： A pressure-assisted flush water tank includes a fluid container, a Venturi nozzle, a baffle and a buoy. The fluid container has an accommodating chamber, a water channel and an air channel. The accommodating chamber has a fluid inlet. The water channel and the air channel are in communication with the fluid inlet. The Venturi nozzle is disposed at a junction of the water channel and the fluid inlet. The baffle is configured to seal the air inlet in a movable manner. The buoy is disposed on an inner side of the air inlet. The top end of the buoy leans against the baffle. The buoy rises under internal pressure of the fluid container until the air inlet is closed. Before the buoy closes the air inlet, the protruding post abuts against and lifts up the baffle to open the air inlet.

摘要： An educator assembly for a toilet includes a suction reservoir, a flow driving device, a first nozzle, a second nozzle, and a discharge outlet. The suction reservoir is configured to store a supply of water. The flow driving device is configured to supply a flow of water to the eductor assembly and in fluid communication with the suction reservoir to create a suction port proximate to the flow driving device and the suction reservoir. The first nozzle is at the end of the flow driving device. The second nozzle is downstream of the suction port. The discharge outlet is coupled to a trapway of the toilet and configured to receive discharge from the second nozzle downstream of the suction port.

摘要： The disclosed technology includes a tank system including a gravity tank configured to contain water at atmospheric pressure, a rigid pressurized tank positioned within the gravity tank and configured to contain water at a pressure greater than atmospheric pressure, and a piston assembly positioned below the rigid pressurized tank and configured to open and close the rigid pressurized tank. The gravity tank is configured to channel water at atmospheric pressure into a toilet bowl at a first velocity and the rigid pressurized tank is configured to channel water at the pressure greater than atmospheric pressure into the toilet bowl at a second velocity. The second velocity is greater than the first velocity.

摘要： An air drive system for a toilet includes a compression cylinder including an air space, a fluid space, a base orifice adjoining the fluid space, and an outlet orifice adjoining the air space, and an air drive passage configured to carry pressurized air to the toilet. The flow of water increases the fluid space of the compression cylinder or increases an air pressure associated with the air space of the compression cylinder.

摘要： A flush valve includes a valve housing defining a fluid passageway between a fluid inlet and a fluid outlet. The fluid passageway includes a diaphragm valve seat disposed between the fluid inlet and the fluid outlet. The flush valve additionally includes a diaphragm assembly including a diaphragm and a disc. The diaphragm includes a primary opening and a bypass opening. The primary opening receives the disc therein and the bypass opening allowing water under pressure supplied to the fluid inlet to pass from a fluid inlet side of the diaphragm into a chamber in the fluid passageway. The flush valve additionally includes a relief valve configured to selectively control fluid flow from the chamber to the fluid outlet. The relief valve comprises a stationary valve element and a rotatable valve element each having at least one opening and being rotationally positionable relative to one another to regulate fluid flow.

摘要： An explosion-proof method of an explosion-proof pressure type toilet tank, includes dividing the toilet tank into a closed air container to store air and a closed water container to store water. The water container is disposed with an inlet and an outlet. The air container is connected to the water container by a channel. The air container compressive ultimate strength is larger than that of the water container. When the tank is filled with water, the air in the water container enters the air container through the channel. When the tank pressure is too great, the water container bursts, steadily releasing the air compression of the air container through the channel to prevent the compression air from quickly blowing out.

摘要： One embodiment of the present application relates to a water tank for a toilet. The water tank includes a first chamber comprising an orifice for connecting to a toilet bowl. The water tank further includes a free-floating member within the first chamber that is not coupled to any other component and that is configured to selectively engage with and disengage from the orifice to selectively block or allow a flow of water through the orifice. The free-floating member can be selectively disengaged from the orifice via an actuator or a differential pressure within the water tank.
