An air cooling conveying structure is arranged in the air cooling heat dissipation channel 9, the air cooling conveying structure usually adopts a fan or a fan, the power of the fan or the fan does not need to be additionally increased, and the fan or the fan is only required to be arranged on the rotating shaft 10 of the motor 2, although the motor 2 drives the piston 5 to reciprocate, so the fan or the fan can be arranged at two end parts of the rotating shaft 10 of the motor 2 in order to avoid interference with the crank 7.
The motor 2 of the embodiment adopts an outer rotor motor, and the outer rotor motor is characterized in that the rotor 11 and the stator 12 are provided with the hollow parts 13, so that the heat of the motor 2 can be dissipated as long as air flows in the hollow parts 13, and meanwhile, when the rotor 11 rotates, the hollow parts on the rotor 11 can be vane type, so that the air circulation is further accelerated.
The axial fan 14 installed at one end of the rotating shaft 10 of the motor 2 functions to allow air to pass through the inside of the motor 2.
Since the air cooling heat dissipation channel 9 is a channel, the air cooling heat dissipation channel has an air inlet 15 and an air outlet 16, the whole channel is in a C shape, and the air compressor is half-wrapped, so that the motor 2, the cylinder body 4 and the cylinder cover 6 are covered. The air passing through the inside of the motor 2 is turned by the centrifugal fan 17 at the other end of the rotating shaft 10 of the motor 2 and blown to the cylinder 4 and the cylinder cover 6. In the process, each turning position of the air in the air-cooled radiating channel 9 should be arc-shaped, so that the air circulation can be smoother.
In order to enable air to flow to the cylinder body 4 and the cylinder cover 6 from the position of the motor 2, a fan cover 18 which covers and wraps one side of the motor 2 where the centrifugal fan 17 is installed and the top of the cylinder cover 6 is specially designed, the fan cover 18 is designed into a split type for facilitating production, installation and later maintenance, and comprises a left half housing 19, a right half housing 20 and a top housing 21, the left half housing 19 and the right half housing 20 are fixedly connected to form an inlet 22 and an outlet 23, a fan chamber 24 is formed between the left half housing 19 and the right half housing 20, and the centrifugal fan 17 is located in the fan chamber 24; the inlet 22 is communicated with the space where the vent hole 13 of the outer rotor 11 is positioned, and the outlet 23 is connected with and communicated with the inlet of the top cover shell 21; the compression cylinders 3 of the invention are provided with two groups which are respectively arranged at the left side and the right side above the motor 2, the top encloser 21 covers the cylinder covers 6 of the two groups of compression cylinders 3, so that the two cylinder covers 6 are both arranged in the air-cooled heat dissipation channel 9, namely, a linear ventilation space 25 is formed above the two cylinder covers 6, and in addition, the outlet of the top encloser 21 is communicated with the outside, so that the heat is taken out of the air compressor.
And the two groups of compression cylinders 3 enable the motor 2 to be a double-shaft motor, and the axial flow fan 14 and the centrifugal fan 17 are reasonably and mutually noninterfere arranged at the two ends of the motor.
The plurality of radiating fins 8 on the cylinder cover 6 are in an S shape, the S shape can be designed into a wave shape or other shapes, as long as the air flow dynamics is not violated, the radiating fins 8 in the shape form an air flow space 26 in a corresponding shape between two adjacent radiating fins 8, and therefore the air flow space 26 and the linear ventilation space 25 are not parallel to each other, specifically, the two spaces are in a certain crossed shape, and the crossed included angle is small, so that the air flow is prevented from being disturbed.
When wind is blown to the linear ventilation space 25 by the centrifugal fan 17, the wind flows linearly along the linear ventilation space 25, when the wind passes through the cylinder cover 6, the air near the discrete heat fins 8 is influenced by the wind flow spaces 26 which are not parallel to each other, and the path track changes, however, the wind flows in the general direction along the linear direction of the linear ventilation space 25, only in the position, the time spent by the air flowing is longer than the time spent by the air flowing far from the discrete heat fins 8, so that the exchange time of the heat energy on the surfaces of the heat radiating fins 8 and the air is longer, the heat radiation is more thorough, meanwhile, the air flowing far from the discrete heat fins 8 is faster, and therefore, the heat energy exchanged to the air can be timely taken away by the air, and the heat radiation effect is greatly improved.

In order to realize the air cooling effect, the air inlet 30 is designed on the shell 29 of the air compressor, the air inlet 30 is aligned with the coil on the stator 28, because when the motor 31 works, a large amount of heat is radiated through the coil, the coil of the stator 28 is positioned at two ends, two groups of air inlets 30 are designed, which respectively correspond to the coils at two ends, thus, when the air is sucked into the air compressor by the centrifugal fan 32, the air is blown to the coil, so that the heat generated by the work of the motor 31 can be driven, then, the flowing air flows to the cylinder cover 33 through the centrifugal fan 32, and then the heat is radiated to the cylinder cover 33, the air cooling conveying structure comprises two centrifugal fans 32, and the two centrifugal fans 32 are respectively arranged at two ends of the rotating shaft 34 of the motor 31; the air-cooling heat dissipation passages 35 are provided with two groups, which are respectively installed on two sides of the air compressor, and each group is formed by sequentially communicating an air inlet 30, which is arranged on the housing 29 and matches with a coil of the motor 31, a space (which is actually a space enclosed between the fan housing and the air compressor) contained in the fan housing 36 covering and wrapping the side surface of the motor 31 and the top of the cylinder cover 33, and an air outlet 37 formed between the fan housing 36 and the cylinder cover 33.

Therefore, the handle 38 not only realizes the effect of lifting the whole air compressor, but also partially shields the air outlet 37, so that the air flows to the radiating fins 40 of the cylinder cover 33 from the air in a more concentrated manner, the pressure of the air at the positions of the radiating fins 40 is greatly improved, and the radiating effect is more beneficial.
The centrifugal fan 32 is located in the fan housing 18, and an air deflector 41 is disposed on an inner wall of the fan housing 36 between the centrifugal fan 32 and the air outlet 37.
