Abstract: A mixed water control valve having a body and a spindle is disclosed. The body has two inlet pipes and two outlet pipes which are longitudinally corresponding to the two inlet pipes. The two inlet pipes are branched into a upper inlet pipe and a lower inlet pipe which are disposed in different height positions. The spindle is rotatably assembled in the body. The spindle has an upper and a lower inlets corresponding to the height of the upper and the lower inlet pipe and. The spindle also has an upper outlet and a lower outlet respectively corresponding to the two outlet pipe. Thereby, the spindle is detachable and convenient to repair and replace and the spindle is also capable of changing mounting directions to change the flowing directions of water and then to match the different arrangements of the inlet pipes of cold and hot water.

Abstract: A water dispensing device capable of recycling cold water comprises a mixing valve connected with a first pipe for supplying cold water and a second pipe for supplying hot water; at least one watering member connected with an output end of the mixing valve; a bucket connected with the output end of the mixing valve and the first pipe to store water from the mixing valve; a control unit being used to sense a temperature of the water flow passing through the mixing valve; as a sensed temperature is less than a set value, the cold water stored in a pipe system will be guided to recycle toward the bucket and to be supplied to the first pipe, obtaining recycling and reusing purpose; while the sensed temperature is more than the set value, the cold water stored in the pipe system will be guided to flow toward the watering members.

Abstract: A quantitative refill device is mounted on the top end of an overflow pipe in a water tank of a water saving toilet and comprises a first pipe, a second pipe and a float device. The second pipe defines a second chamber. Initially, water flows to the overflow pipe to create a water closing through a water flow passage between the second pipe and the float pipe, especially a conical passage defined between a conical surface of the second pipe and a conical portion of the float device. Meanwhile, the float device moves upward along with the rise of the water level of the second chamber to close the conical passage. By the time the conical passage is closed, the water closing is formed, and the refilled surplus water will overflow into the water tank, thus creating a quantitative water refilling effect.

Abstract: A water flow temperature control system is described. A hot and cold water flow respectively flow through a first and a second inlet passage of a valve and reach a temperature control sheet through a pressure equalization valve and two water seals. The quantities of the water flows are controlled by changing positions of two large or two small tapered adjusting holes on the temperature control sheet relative to the two water seals before flowing towards a water mixer of a mixing device. The water flows enter from a large opening portion of the water mixer, and are mixed in a helical direction. After that, the water flows pass through a number of outlet holes on a small opening portion of the water mixer towards an outlet passage of the valve. The center of the temperature control sheet is connected to a first end of a transmission shaft.

Abstract: A pressure vessel at least includes a main vessel, an air entry valve, a water entry valve, a drain valve and a control valve. The drain valve is provided with a valve base set on the top of the main vessel, a piston unit inserted inside the valve base able to be moved upwards and a spring installed between the piston member and the valve base. In addition, the pressured water in the main vessel coming from the water entry valve and the air entry valve can be stored in the control valve and guided to a chamber between the piston unit and the valve base, enabling the piston member to surpasses the elasticity and the water pressure to move up to separate from a drain exit of the main vessel for flushing a toilet. Therefore, the present invention has a simple structure, easy to assemble, preventing accidental flushing.

Abstract: A toilet, including: a bowl member having a contraction portion, which is narrowed from a top to a bottom thereof. There is a water passing rim provided at the top rim of the contraction portion. A receiving portion is provided below the contraction portion. The receiving portion connects with a discharging pipe. A water tank places at one side of the bowl member. The water tank has an exit. A divided pipe places under the tank and connects with the exit. The divided pipe has a first exit and a second exit. A down tunnel connects with the second exit of the divided pipe in one end and with the receiving portion in the other end. The end of the down tunnel that connects with the receiving portion points to the discharging pipe and forms a jet water delivery port. The down tunnel has a downward section. A water rim duct connects with the first exit of the divided pipe in one end and the water passing rim in the other end.

Abstract: A toilet includes a bowl having a receiving portion, a converging portion in front of the receiving portion, an injecting portion and an inlet portion at opposite ends of the converging portion, and a discharging pipe behind the receiving portion and communicated with the receiving portion. The bowl has an inlet at an end thereof to communicate outside, two down tunnels on opposite side of the bowl with ends communicated with the inlet and ends extended downwards to a position in front of the receiving portion. Each of down tunnels has a U-turn section that the down tunnels have inward U-turns and are communicated with the converging portion, such that water flowing through the down tunnels will converge together in the converging portion for injecting to the discharging pipe.

Abstract: A pressure vessel has a tank portion for preserving water and a drain mechanism mounted on the tank portion. An outlet is defined at a bottom of the tank portion for draining water. A through hole is defined at a top of the tank portion and corresponding to the outlet for mounting the drain mechanism thereon. The drain mechanism includes a hollow pipe and a separating plate extending horizontally from an inner side and near a top of the hollow pipe. An actuator is assembled on a top of the separating plate for manual operation and has a first resilient element mounted therein. At least a pivot element pivotably connects with the actuator and each forms an anchor at a lower end thereof. A pole extends longitudinally through an interior of the hollow pipe. The pole forms a flange at a top thereof, and defines at least a groove near the flange for latching the anchors.
