The main working principle of the existing air compressor is as follows: the motor directly drives the compressor to make the crankshaft rotate and drive the connecting rod to make the piston reciprocate to change the volume of the cylinder. Because of the change of the pressure in the cylinder, the air enters the cylinder through the air filter by the air inlet valve, in the compression stroke, the compressed air enters the air storage tank by the exhaust valve under the action of the exhaust valve and the one-way valve (check valve) by the reduction of the volume of the cylinder, when the exhaust pressure reaches the rated pressure of 0.7MPa, the air storage tank is automatically stopped by the control of the pressure switch, and when the pressure of the air storage tank is reduced to 0.5-0.6 MPa, the pressure switch is automatically connected and started.
Therefore, it is known that the pressure in the air storage tank of the pressure vessel is very high, and the air storage tank may explode if the pressure vessel is impacted by external force, the pressure switch fails or the ambient temperature changes too fast, so that the conventional air compressor needs to be further improved to prevent the dangerous situation that the pressure of the air storage tank exceeds the safety value under the above circumstances.
