The air compressor contains a casing member, a driving member, and a cylinder member. The casing member has a first accommodation section, a second accommodation section, and a connection section connecting the first and second accommodation sections. The first accommodation section has a number of first inlets and first outlets. The driving member is located between the first and second accommodation sections, and is adjacent to the first outlets. The cylinder member is located both in the second accommodation section and the connection section, and is adjacent to the second outlets. The outside cool air is drawn into the casing member through the first inlets. A portion of the drawn air is released through the first outlets, forming a first flow path for cooling down the driving member. Another portion is released through the second outlets, forming a second flow path for cooling down the cylinder member.

1. An air compressor, comprising: a casing member having a hollow first accommodation section, a hollow second accommodation section, and a hollow connection section located above and connecting the first and second accommodation sections, where the first accommodation section has a plurality of first inlets on a front side and a plurality of first outlets on a back side of the first accommodation section, the connection section has a plurality of second outlets adjacent to the second accommodation section;a driving member comprising a motor and a fan, where the motor is located outside the casing member between the first and second accommodation sections, and the fan is housed in the first accommodation section and joined to a first end of a shaft of the motor;a cylinder member located both in the second accommodation section and the connection section adjacent to the second outlets and engaged by the driving member;a partition plate configured inside the connection section adjacent to the first accommodation section extended from an inner wall of the connection section towards the second outlets;an inlet pipe located inside the connection section having a first end connected to the second accommodation section, a second end located above the partition plate opening towards the second outlets, and a curved section in-between adjacent the second end;an outlet pipe located inside the connection section having a first end connected to the cylinder member;wherein the fan draws outside cool air into the casing member through the first inlets; a portion of the drawn air is released outside through the first outlets, thereby forming a first flow path;the first outlets are adjacent to a bottom edge of the back side of the first accommodation section and beneath the motor for cooling down the motor;a part of another portion of the drawn air, under the guidance of the partition plate, is released outside through the second outlets, thereby forming a second flow path for cooling down the cylinder member; andanother part of another portion of the drawn air enters the second end of the inlet pipe in a direction opposite to the second flow path and then into the second accommodation section, cooling down the cylinder member while effectively avoiding dust particles in the outside air entering and damaging the cylinder member. 2. The air compressor according to claim 1, wherein the cylinder member comprises a cylinder, a connecting rod, and a tube; the cylinder is located inside the connection section above the second accommodation section; the connecting rod has one end joined to a piston and the other end joined to a crank shaft; the piston is housed inside the cylinder; the crankshaft is housed in the second accommodation section and joined to a second end of the shaft of the motor; the tube is joined to a top cover of the cylinder; and the tube has an outlet connected to the first end of the outlet pipe.
