Problems solved by technology
Existing air compressors generally have only one cylinder, that is, only one group of air compression components including pistons and cylinders. At the same time, when compressing air, the air only enters and exits in one direction; the existing problem is: The effect and efficiency of air compression are relatively low with only one set of air compression components

The invention discloses a linear double-piston air compressor. The linear double-piston air compressor comprises a crank case, an air cylinder body with two air cylinders, a crank and two piston devices connected with the crank. The crank penetrates the crank case, and two connecting rod shaft necks in the crank are symmetrically arranged along a main shaft. Each piston device comprises a connecting rod connected with the corresponding connecting rod shaft neck of the crank. The connecting rods are connected with piston rods through cross-shaped connectors, and the piston rods are connected with piston heads. The piston heads are arranged in the air cylinders. The two sealed air cylinders are formed in the air cylinder body. Two air inlet valves and two air outlet valves are arranged above each air cylinder, and two air inlet valves and two air outlet valves are arranged on each of the two sides of each air cylinder. Oil scraper rings are further arranged in the crank case, and the piston rods penetrate the oil scraper rings. Filler is arranged below the air cylinders of the air cylinder body, and the piston rods penetrate the filler. The double cylinders and the double pistons are adopted in the linear double-piston air compressor, and the air compression effect and efficiency of the linear double-piston air compressor are high.
Description
technical field [0001] The invention relates to the technical field of air compressors, in particular to a linear double-piston air compressor. Background technique [0002] Existing piston air compressors generally include structures such as a motor, a crankcase, an eccentric wheel, and an air compression assembly. The eccentric wheel is connected to the motor shaft and is located in the crankcase. As the eccentric wheel rotates, the air compression assembly moves back and forth to compress air. Existing air compressors generally have only one cylinder, that is, only one group of air compression components including pistons and cylinders. At the same time, when compressing air, the air only enters and exits in one direction; the existing problem is: The air compression effect and efficiency of only one group of air compression components are relatively low. Contents of the invention [0003] The object of the present invention is to provide a linear double-piston air com...
