Abstract

The invention provides a linear compressor. The linear compressor comprises a machine shell, a linear motor, an air cylinder, a first piston, a connecting rod and a second piston. The linear motor comprises a stator, a first rotor and a second rotor. The air cylinder defines a first compression cavity and is provided with a first exhaust valve. The first piston is arranged in the first compressioncavity, provided with a first air suction hole and provided with a first air suction valve. The connecting rod is connected with the first piston, is driven by the first rotor to drive the first piston to reciprocate and is provided with a second compression cavity communicating with the first air suction hole. The second piston is inserted into the second compression cavity, provided with a second air suction hole and provided with a second air suction valve. When the first piston moves towards the first exhaust valve, the second piston is driven by the second rotor to gradually get away from the first piston, so that gas in the second air suction hole pushes the second air suction valve to enter the second compression cavity; and when the first piston moves away from the first exhaust valve, the second piston gradually gets close to the first piston, so that gas in the second compression cavity is compressed by the second piston to push the first air suction valve to enter the firstcompression cavity. By means of the linear compressor, the air suction amount is increased through multi-stage compression.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a linear compressor. Background technique [0002] A linear compressor is a piston compressor using a linear motor, which is mainly used in refrigerators, freezers and other low-temperature refrigeration systems. [0003] However, the energy efficiency of linear compressors with conventional structures is still not high enough, which greatly limits their popularization and use in the field of refrigeration. Contents of the invention [0004] An object of the present invention is to provide a linear compressor with higher suction efficiency, so as to improve the energy efficiency of the compressor. [0005] Another object of the present invention is to make the multi-stage compression structure of the linear compressor simpler and more reliable. [0006] A further object of the present invention is to make the compression power of the second piston stronger. [0007] In p...
