Problems solved by technology

[0002]Although the existing linear compressors can adjust the cylinder volume to meet the needs of different working conditions, they often have the problem of poor adjustment effect. The reason is , on the one hand, the adjustment accuracy is low, and it is impossible to adjust in a small range; The magnetic attraction is used as the driving force of the linear motor to drive the piston to reciprocate, which also leads to it being easily affected by the magnetic field. When a force is generated in a direction perpendicular to the direction of the piston movement due to the uneven magnetic field, it will As a result, the friction force between the piston and the cylinder increases, and a certain amount of driving force is easily lost, the compression efficiency is reduced, and what is more fatal is that the circumferential direction of the piston is worn.

Abstract

The invention discloses a linear compressor with an adjustable cylinder volume, and relates to the technical field of linear compressors. The linear compressor comprises a flange, a stator part fixed at one side of the flange, a rotor which is connected with the stator part in a sliding manner and can drive a piston mechanism to slide synchronously, and an air cylinder component embedded into the side, away from the stator part, of the flange in a sliding mode, wherein the embedding degree between the air cylinder and the flange can be changed through relative sliding, and therefore the volume of the air cylinder is changed.

Description

technical field [0001] The invention relates to the technical field of linear compressors, in particular to a linear compressor with adjustable cylinder volume. Background technique [0002] Although the existing linear compressors can adapt to the needs of different working conditions by adjusting the cylinder volume, they often have the problem of poor adjustment effect. On the other hand, when adjusting, it is often necessary to disassemble other connected parts before adjusting, which is inconvenient. In addition, the existing linear compressor uses magnetic attraction as the driving force of the linear motor to drive the piston Reciprocating motion, which also causes it to be easily affected by the magnetic field, when a force is generated in a direction perpendicular to the direction of piston movement due to uneven magnetic field, it will cause the friction between the piston and the cylinder to increase, and it is easy to lose A certain driving force reduces the com...
