Abstract

The utility model relates to a structure-improved air compressor, which is composed of a motor, a fixed seat, a driving device, and a compressing device. The fixed seat is provided with the motor provided with a shaft lever via a fixed screw rod. After the shaft rod of the motor passes through the through hole of the shaft lever of the fixed seat, the shaft rod is embedded with a matching block inside an accommodating chamber of the driving device. The motor power is coupled with the driving device via the shaft rod for operation. The pivot bar of the matching block drives a connecting rod, and the connecting rod drives the piston body, compression valve plates, compression positioning blocks to do the reciprocating motion inside a compression tube. The air can be pushed to a top pipe and then is output to realizing the favorable compression ratio for air circulation. The utility model has thermolysis effect and overcomes the defect that the traditional engaged gearwheel is easy to grind and the gearwheel dent is easy to damage.
