The invention discloses a single inlet/outlet micro-scale constant volume combustion device which comprises an enclosed combustion chamber, an ignition device and a gas inlet/outlet pipe, wherein the ignition device and the gas inlet/outlet pipe are connected with the combustion chamber. The gas inlet/outlet pipe is provided with a four-way switching valve. The four-way switching valve is connected with a gas inlet pipe, a gas outlet pipe and a vacuum pipe having a vacuum pump. The ignition device is communicated with the gas inlet/outlet pipe. The beneficial effects of the combustion device are that the gas inlet/outlet pipe is provided with the four-way switching valve, and the four-way switching valve reduces limited diameter and connection length of the connection pipe, so that influence of external volume on the inner portion can be reduced, and meanwhile, the influence of the opening on the surface of a combustion field is reduced; and the combustion device is especially suitable for small-scale and micro-scale constant volume combustion. When a unidirectional conducting spring piece is adopted, external volume influencing space can almost be neglected, and experiment accuracy is improved.
