[0019] As Figure 1 、 Figure 2 shown, this reciprocating piston air compressor includes an air compressor body 1 and a driving motor. The air compressor body 1 is provided with a plurality of piston cylinder mechanisms 2. An air-cooling mechanism for air-cooling and heat dissipation is arranged outside the air compressor body 1. The transmission shaft of the driving motor is sequentially connected to the air compressor body 1 and the air-cooling mechanism, and is connected to the plurality of piston cylinder mechanisms 2 through a crank connection mechanism for transmission connection. The air-cooling mechanism is directly driven to work by the transmission shaft of the driving motor. The air-cooling mechanism includes an air intake cylinder 5 for air-cooling the intake air, a main fan 3 for air-cooling and heat dissipation, an auxiliary fan 4 for improving the air-cooling efficiency, a protective housing 6 for protection, and an air intake grille 7 installed on the protective housing 6. A plurality of air intake holes 8 facilitating the entry of gas are opened on the air intake cylinder 5. The main fan 3 and the auxiliary fan 4 are respectively connected to both ends of the air intake cylinder 5 and are provided as an integrally formed structure.

[0020] The above structure is simply designed. It adopts a direct-connected air-cooled structure, which combines the air-cooling mechanism structure and the heat dissipation fin 9 structure to effectively air-cool the outside of the piston cylinder mechanism 2 and the main body of the air compressor, and at the same time, air-cool the intake pipeline and the exhaust pipeline, greatly alleviating the problem that the internal heat accumulation cannot be dissipated, and improving the service life and efficiency of the air compressor.

[0021] To elaborate further, in order to improve the air-cooling of the outside of the piston cylinder mechanism 2 and the air compressor body 1, the main fan 3 is composed of a connecting portion 10 connected to the end corresponding to the intake cylinder 5 and having a conical structure, and a plurality of blades 11 for air-cooling. The plurality of blades 11 are arranged at intervals in a vortex structure along the outside of the connecting portion 10. The outside of the piston cylinder mechanism 2 is all provided with heat dissipation fins 9 for improving the heat dissipation efficiency. The protective housing 6 is connected to the outside of the plurality of piston cylinder mechanisms 2 and enables the outside of the piston cylinder mechanism 2 to be quickly air-cooled through the air-cooling mechanism. By using the structural cooperation of the main fan 3, the auxiliary fan 4 and the protective housing 6, air-cooling is carried out on each mechanism on the air compressor body 1, greatly alleviating the problem of heat accumulation.

The intake pipeline and the exhaust pipeline pass through the inside of the protective housing 6 and are air-cooled through the air-cooling mechanism.

[0023] Preferably, the outside of the air compressor body 1 has a connection end cover that facilitates the installation of the air-cooling mechanism.
