Air compressor

摘要

An air compressor with enhanced air compressing effect comprises a mounting chassis with a coupling aperture, a piston having a piston rod with a crankpin linking bore and a piston head with an air acting face, a cylinder having an air chamber with an inner top wall, and a driving mechanism including a motor having a shaft and a rotational crank cam with an eccentric crankpin. The coupling aperture on the mounting chassis is bias disposed relative to the axial line of the cylinder. Both of the air acting face on piston head and inner top wall in cylinder are configured into corresponding slant planar surface. The eccentric crankpin on the crank cam pivotally links the crankpin linking bore on the piston rod of the piston so that rotary motion of the crank cam is converted into linear reciprocating motion. Thus, air compressing effect is substantially enhanced.

主权项

1. An air compressor, comprising:
a housing includes a cylinder and a mounting chassis with a proximal coupling aperture and a distal coupling aperture such that a hypothetically extended normal line initiated from the central point of the distal coupling aperture and extended in a direction toward a piston and perpendicular to the mounting chassis does not intersect with an axial line initiated from an internal central point of the cylinder, wherein said mounting chassis serves to fix a driving mechanism thereon and the proximal and distal coupling apertures are configured to accommodate the driving mechanism; the piston includes a piston head at a front end thereof and a piston rod with a crankpin linking bore at a rear end thereof such that said crankpin linking bore can be driven by the driving mechanism while said piston head is accommodated by the cylinder for performing linear reciprocating motion therein; wherein the top surface of said piston head of the piston is formed into an air acting face with a slant profile that is not a flat plane perpendicular to the piston rod; and wherein said cylinder includes an air chamber encompassed by an inner top wall, a cylindrical inner wall and the air acting face of the piston, such that the inner top wall is formed with a slant profile that is not a flat plane perpendicular to the longitudinal axis of the cylinder, said slant profile of the inner top wall corresponding with the slant profile of the air acting face on the piston head of the piston; and wherein the longitudinal axis of the piston rod is substantially parallel to the longitudinal axis of the cylinder when the piston head reaches a reflection point during the linear reciprocating motion.
