Further, described elastic supporting member for supporting optical member is multiple extension springs being evenly distributed on described mover or described piston outer periphery.
Further, described piston includes that piston rod and piston head, described piston rod and described piston head flexibly connect.
Further, the joint face of described piston rod and described piston head is arcwall face.
The linear compressor that this utility model provides, supports the afterbody of piston by elastic supporting member for supporting optical member, and piston moves reciprocal
The elastic supporting member for supporting optical member axis along piston will be made to produce elastic deformation during Dong, and owing to elastic supporting member for supporting optical member has along piston
Moving direction produces the degree of freedom of elastic deformation, thus meets the movement requirement of piston, and meanwhile, elastic supporting member for supporting optical member is in other directions
The degree of freedom of generation elastic deformation limited, such that it is able to guarantee the afterbody of piston is effectively supported, so that living
Plug and cylinder meet the requirement of axiality, and owing to the afterbody of piston will not produce friction in motor process, effectively reduce
Amount of friction, it is achieved reduce the friction loss of linear compressor, improving the efficiency of linear compressor.

Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, new below in conjunction with this practicality
Accompanying drawing in type embodiment, is clearly and completely described the technical scheme in this utility model embodiment, it is clear that retouched
The embodiment stated is a part of embodiment of this utility model rather than whole embodiments.Based on the enforcement in this utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into
The scope of this utility model protection.
As in figure 2 it is shown, the present embodiment linear compressor, including shell 1 and be arranged on the mover 2 in described shell 1,
Stator 3, cylinder 4, piston 5, resonant spring 6 and spring bearer plate 7, also include that elastic supporting member for supporting optical member 8, described elastic supporting member for supporting optical member 8 are arranged
Between described spring bearer plate 7 and described mover 2, described piston 5 or described mover 2 are connected on described elastic supporting member for supporting optical member 8, institute
State elastic supporting member for supporting optical member 8 and there is the degree of freedom producing elastic deformation along described piston 5 moving direction.
Specifically, the rearward end of piston 5 is supported by the present embodiment linear compressor by elastic supporting member for supporting optical member 8, by
Elastic deformation can be produced on piston 5 moving direction in elastic supporting member for supporting optical member 8, thus in piston 5 reciprocating movement, piston
5 can overcome the elasticity of elastic supporting member for supporting optical member 8 to move, and elastic supporting member for supporting optical member 8 degree of freedom in the other direction is limited simultaneously,
Such that it is able to the afterbody of piston 5 is effectively supported by elastic supporting member for supporting optical member 8, piston 5 in reciprocating movement, piston
The afterbody of 5 will not produce friction, such that it is able to effectively reduce amount of friction.
Wherein, the structure of elastic supporting member for supporting optical member 8 can take various forms.Such as: as shown in Figures 2 and 3, elastic supporting member for supporting optical member
8 is flat spring, and described flat spring offers multiple through hole 81, and described resonant spring 6 is inserted in the described through hole 81 of correspondence, and
Flat spring can be directly anchored on spring bearer plate 7, and flat spring can be concentric spirals arm flat spring, eccentric vortex spiral arm flat spring
Or linear arm flat spring, it is preferred that it is additionally provided with cushion (not shown) between flat spring and described spring bearer plate 7, by bullet
Property pad is so that flat spring extrudes cushion in the case of being perpendicular to piston 5 axis direction power and deforms, with balance plate bullet
Power suffered by spring, so that piston 5 moves more smoothly；Or, as shown in Figure 4 and Figure 5, elastic supporting member for supporting optical member 8 be multiple all
The even extension spring being distributed in described mover 2 or described piston 5 periphery.
It addition, described piston 5 is generally made up of piston rod and piston head so that piston head can more smooth out
Moving in cylinder 4, described piston rod and described piston head flexibly connect, when because the factors such as rigging error cause the work of piston 5
When the axis coaxle degree of stopper rod and cylinder 4 has deviation, due between piston rod and piston head for flexibly connecting, piston rod can be relative
Small swing is there is, to guarantee the movement that piston head smoothes out in cylinder 4, it is preferred that piston rod and described work in piston head
The joint face of chock plug is arcwall face.
The present embodiment linear compressor, supports the afterbody of piston by elastic supporting member for supporting optical member, and piston is in reciprocating movement
The elastic supporting member for supporting optical member axis along piston will be made to produce elastic deformation, and owing to elastic supporting member for supporting optical member has along piston moving direction
Producing the degree of freedom of elastic deformation, thus meet the movement requirement of piston, meanwhile, elastic supporting member for supporting optical member is at the generation bullet in other directions
Property deformation degree of freedom limited, such that it is able to guarantee that the afterbody to piston effectively supports, so that piston and cylinder
Meet the requirement of axiality, and owing to the afterbody of piston will not produce friction in motor process, effectively reduce amount of friction,
Realize reducing the friction loss of linear compressor, to improve the efficiency of linear compressor.
