Air compressors are commonly used air power source equipment for providing compressed high pressure air, for providing air power to pneumatic tools (e.g., pneumatic nailers, sanding tools, painting tools, etc.) or for inflating, etc.
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.
However, when the existing air compressor is used for inflating other equipment, if an inflation gun is always inflated on the equipment and is forgotten to be pulled out, or the air pressure borne by the equipment is small, dangerous situations can be caused due to overlarge inflation pressure.

Because the pressure values born by different inflation equipment are different in size, the air pressure threshold of the inflation gun 52 is set to be the pressure value born by the inflation equipment, and therefore when the pressure value in the air cylinder 1 measured by the pressure gauge 4 reaches the set air pressure threshold, the controller 6 controls the motor 2 to stop running, so that the pressure in the air cylinder 1 cannot exceed the pressure value born by the inflation equipment, and the dangerous situation cannot occur naturally. In addition, the inflation gun 52 of the present application can also measure the air pressure in the inflation device by the air pressure meter, and when the measured air pressure value is the air pressure threshold value, the controller 6 can also control the motor 2 to stop running, so as to further avoid that the air pressure in the air cylinder 1 is too high, which leads to the too high air pressure in the inflation device.
