The main unit 2 in the utility model adopts an oil-free silent air compressor head, which belongs to a micro reciprocating piston compressor, mainly including a horizontal motor, a double cylinder structure or a four-cylinder structure located on both sides of the motor, and the two ends of the motor are respectively connected to a crank mechanism, and the crank mechanism drives the piston in the cylinder to move. The use of a multi-cylinder structure can provide sufficient high-pressure gas, and can also provide relatively high-pressure gas while reducing the volume and noise. In the utility model, the multi-cylinder structure shares an air inlet and an air outlet, and multiple cylinders are connected through an air inlet pipe and an exhaust pipe. The utility model is mainly used for spraying, inflation and other tasks. The air compressor head and the tube reel device are combined together so that the tube reel device comes with an air compressor for easy use. The main improvement of the utility model is that a one-way valve 42 is provided in the air duct 41. The one-way valve 42 can close the air duct 41 when not inflated, maintain the pressure in the air duct 41, thereby preventing the main engine 2 from being frequently started due to loss of pressure, causing the motor coil to burn out.
