The application relates to a small-sized compressor with oil-gas separation, and relates to the technical field of small-sized compressors, and comprises a compressor main body, an oil-gas separator and a lubricating oil recovery system. The application improves the oil-gas separation efficiency by arranging a cyclone separation device and a spiral flow guide structure. When compressed air enters the separation cavity from the compressed air exhaust port of the compressor main body, the spiral flow guide structure first guides the airflow to preliminarily rotate, so that part of oil droplets are thrown to the cavity wall under the action of centrifugal force; then the airflow flows through the cyclone separation device, the rotating speed is further improved, and the remaining oil droplets are completely separated. Compared with the traditional single centrifugal separation, the double rotation strengthens the separation effect of the oil droplets and the air, solves the problem of low separation efficiency at low rotating speed, and enables the clean air after separation to be stably discharged from the clean air exhaust port; the cyclone separation device is adopted to replace the filter element of the traditional filtering separation, thereby reducing the maintenance cost.
