Embodiment Construction

[0022] In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Such as Figure 2-Figure 3 As shown, the linear compressor of this embodiment includes a housing 1, and a mover 2, a stator 3, a cylinder 4, a piston, a spring 6, and a spring pressure plate 7 arranged in the housing 1. The stator 3 forms a magnetic field space ( (Not shown), the mover 2 is provided with a magnet 21 inserted i...

Abstract

The invention provides a linear compressor. The linear compressor comprises a shell, a mover, a stator, an air cylinder, a piston, springs and a spring pressure plate, wherein the mover, the stator, the air cylinder, the piston, the springs and the spring pressure plate are arranged in the shell. The stator forms a magnetic field space. A magnetic body is arranged on the mover and inserted into the magnetic field space. The spring pressure plate and the air cylinder are correspondingly fixed to the two sides of the stator. The mover is located between the spring pressure plate and the stator. The springs are arranged between the mover and the spring pressure plate and arranged between the mover and the stator. The piston comprises a piston head and a piston rod which are connected together. The piston head is slidably arranged in the air cylinder. The piston rod is fixedly connected with the mover. A supporting sleeve is arranged on the spring pressure plate. The free end of the piston rod is slidably arranged in the supporting sleeve. The two sides of the piston are supported through the air cylinder and the supporting sleeve, the situation that the piston generates cornering force due to the weight of the mover is avoided, and the reliability of linear compressor is improved.

Description

Technical field [0001] The present invention relates to compressors, in particular to a linear compressor. Background technique [0002] At present, the compressors used in refrigeration equipment have two types: rotary and linear, such as figure 1 As shown, the linear compressor in the prior art usually includes a housing 1, a stator 2, a coil 3, a mover 4, a piston, and a cylinder 6; among them, a magnet 41 is provided on the mover 4, and the magnet 41 is inserted into the outer stator. In the magnetic field space formed by 2, the stator 2 is provided with a coil 3, one end of the piston is connected to the mover 4, and the other end of the piston is inserted in the inner cavity of the cylinder 6. During use, the coil 3 is energized to generate an alternating magnetic field to drive the mover 4 with the piston to reciprocate at high frequency. However, limited by the operating principle of the linear compressor, it is necessary to ensure that the piston and the cylinder 6 are ...
