The invention provides an oil supply control structure, a compressor and an air conditioner, and provides an oil path control structure, the compressor and the air conditioner, the oil path control structure comprises a crankshaft (50), and an oil supply channel (51) extending in the axial direction is arranged inside the crankshaft (50), wherein an oil return mechanism (80) is arranged in the oilsupply channel (51), the crankshaft (50) is further provided with an oil return hole (81) which is in communication with the oil supply channel to the outer peripheral wall of the crankshaft (50), when the rotating speed of the crankshaft is larger than the preset rotating speed, and the oil return mechanism (80) can move in the axial direction until a position of the oil return hole (81) is notshielded, so that the oil supply channel (51) is in communication with the oil return hole (81). According to the oil supply control structure, the compressor and the air conditioner, the oil return amount of lubricating oil can be improved, the phenomenon that lubricating oil is discharged out of the compressor due to the fact that the rotating speed of the crankshaft is too fast is avoided, so that the phenomenon of the lubricating oil shortage in the compressor due to the fact that the excessive speed of the crankshaft leads to the lubricating oil being taken out of the compressor by refrigerants, and the problem that the friction of a matching part is intensified and even burned and glued is effectively solved.
