Abstract: A drainage system for a pressure-assisted flush water tank includes a tank main body and a drainage structure. The drainage structure includes an accommodating chamber and a membrane. The accommodating chamber has a drain outlet, a water inlet, and a drainpipe. The membrane partitions the accommodating chamber into a back-pressure chamber and a drainage chamber and is provided with a supplement hole that communicates the back-pressure chamber with the drainage chamber. The drain outlet is communicated with the back-pressure chamber, while the water inlet and the drainpipe are both communicated with the drainage chamber. The tank main body defines therein a storage chamber communicated with the water inlet. The membrane moves toward or departs from the drainpipe as a pressure in the back-pressure chamber varies so as to close or open the drainpipe.

Abstract: A pressure flushing system including a first container and a second container, and a communicating member that communicates with the first container and the second container; the first container is formed with a first water inlet and a drain, water flows into the first container from the first water inlet, and water in the second container flows in from the first container by means of the communicating member; gas in the first container and the second container is gradually compressed and stored in an upper part of the second container during a water intake process, and the compressed gas pushes the water in the first container and the second container to be discharged from the drain when draining. The present invention solves the disadvantages of the large volume and inconvenient installation of pressure water tank that have existing structures, and has the characteristics of a small volume and flexible installation.

Abstract: A drainage control device includes a main body, an upper cover, a lower cover, a pressure relief cover, a membrane, and a return member. The main body has a water filling trough, a drainage trough, and a water passage trough. A drainage chamber having a drainage port is defined between the upper cover and the drainage trough. A water filling chamber has a water filling port is defined between the lower cover and the water filling trough. The pressure relief cover and the main body hold a periphery of the membrane. A water passage chamber is defined between the membrane and the water passage trough. A back-pressure chamber having a drain port is defined between the membrane and the pressure relief cover. The membrane is configured to open or close a junction of the water passage chamber and the drainage chamber. The membrane is returned by the return member.

Abstract: 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.

Abstract: A noise reduction structure for a toilet tank includes a pressure-assisted flush water tank, a fluid input device, a guide pipe, and a stop member. The fluid input device is disposed on a top of the pressure-assisted flush water tank. The fluid input device is configured to input a fluid having water and air to the pressure-assisted flush water tank. The guide pipe has an input end communicating with an output end of the fluid input device. The stop member includes a stop plate opposite to an output end of the guide pipe. After being stopped by the stop plate, the fluid spreads and flows toward an edge of the stop plate.

Abstract: A water outlet box of a pressure-type flushing system and a toilet using the water outlet box, including a water outlet box main body and a first one-way valve assembly. The water outlet box main body is formed with a water-passing cavity, a water inlet, at least one water outlet and a vent, with the water inlet, the water outlet and the vent all connecting with the water-passing cavity. The first one-way valve assembly is provided opposite to the water inlet to open or block the water inlet, and when the pressure-type flushing system finishes flushing, the first one-way valve assembly blocks the water inlet. The vent is provided at the top of the water-passing cavity and is open to the atmosphere. The water outlet box main body is provided with several water inlet pipes in communication with the functional devices of the pressure-type flushing system.
