Abstract
The present disclosure discloses a gas mixing device and a gas water heating device. In which, a gas mixing device, comprises: a shell provided with a fuel gas channel for inputting fuel gas, an air channel for inputting air and a gas mixing channel, the fuel gas channel being provided with a first cut-off portion capable of changing a flow area, and the air channel being provided with a second cut-off portion capable of changing a flow area; a moving part movable in the shell, the moving part simultaneously changing the flow areas of the first cut-off portion and the second cut-off portions by moving. The gas mixing device and the gas water heating device can provide a higher regulation ratio, thereby solving the problem that the water temperature is too high in summer.
