Oil injected air compressor and method for controlling the same, and storage medium and electronic device

An oil injected air compressor, comprising:

• a compressor assembly configured to compress air;
• an oil separator tank connected to the compressor assembly and configured to separate an oil and air mixture provided by the compressor assembly, wherein oil circulates between the compressor assembly and the oil separator tank;
• an oil cooler assembly connected to the compressor assembly and the oil separator tank and configured to cool the oil;
• an after cooler assembly connected to the oil separator tank and configured to cool compressed air separated from the oil separator tank;
• and
• a controller connected to the compressor assembly, the oil separator tank, the oil cooler assembly, and the after cooler assembly via signals, wherein the controller is configured to control, based on a state switching signal, the oil cooler assembly to operate in an energy-saving state, and the after cooler assembly to operate in a shutdown state or in a minimum speed state;
• wherein the state switching signal is configured to indicate switching of the oil injected air compressor from a heavy loading state to an empty loading state.
