Abstract

The invention discloses a linear compressor with a damping structure, which comprises a closed container, a movable active cell part, a following active cell, an upper spring set, a middle spring set and a lower middle spring set, wherein the following active cell is a mass element or lower piston, a connecting device is connected with a fixed frame through the upper spring set and is connected with the following active cell through the middle spring set, and the following active cell is connected with the bottom surface of the closed container or a lower cylinder through the lower spring set. The linear compressor has the advantages that a spring-mass system consisting of the following active cell and the spring sets is added in a active cell system so as to form a two-degree-of-freedom vibration system, the vibration of the compressor is reduced by using the vibration characteristics of the system, and the application frequency range is wide; and when the excitation frequency is slightly changed, the effect of reducing the vibration can be achieved. A motor, the cylinder and the like of the compressor are fixed inside the closed container, main weights are concentrated on the closed container, and thus the closed container is lower in sensitivity of the vibration so as to be good in stability.

Description

technical field [0001] The invention relates to a linear compressor, in particular to a linear compressor capable of eliminating the transmission of vibration to a closed container due to the reciprocating motion of a piston within a specific frequency range. Background technique [0002] A linear compressor is a device that uses a linear motor installed in a closed container (shell) to perform linear motion, thereby driving the piston to reciprocate, thereby compressing the gas sucked into the cylinder and then discharging it. It mainly includes a closed container and A cylinder, a piston, a linear motor and a connecting device arranged inside a closed container; the cylinder is used to define the compression space, the piston is arranged inside the cylinder in a reciprocating manner, and the top of the piston is provided with a suction valve for introducing gas , The top of the cylinder is provided with an exhaust valve for exporting gas. The linear motor is a drive unit ...
