Description
Technical field
This utility model is related to compressor field, and in particular to a kind of moving-magnetic linear compressor.
Background technology
At present, the linear compressor for being applied to small-power refrigeration plant mainly has 3 kinds of moving-coil type, moving-iron type and moving-magnetic type
Structure type：1) moving-coil type linear compressor adopts permanent magnet or direct current hot-wire coil excitation, moving coil to be placed in magnetic field
And be connected with piston, spring by bracing frame, alternation thrust, compressed gas acting, at this just can be produced after being passed through alternating current
Plant in structure, the useful flux for mostly producing thrust of air-gap flux, therefore moving-coil type compressor has less side
Xiang Li, is easily guaranteed that air gap uniformity, but its specific thrust is little, be not suitable for the compressor of relatively high power；2) moving-iron type compressor
By exchange hot-wire coil excitation, mover is made up of core material, is placed in magnetic field, by action of alternating magnetic field, produces inside mover
Raw faradic current cutting magnetic line movement, moving-iron type linear compressor can provide larger specific thrust, but its mover quality is past
Past larger, inertia force is difficult to balance, and can produce larger vibration and noise；3) operating fields of moving-magnetic linear compressor are by 2
Part constitutes:A part is the alternating magnetic field that stator magnet exciting coil is produced, and a part is the constant magnetic that mover permanent magnet is produced
, under the interaction in 2 magnetic fields, axial driving force being produced, compressed gas are done work, compared with front 2 kinds of types, moving-magnetic type pressure
Contracting machine can provide the specific thrust of maximum under identical input power.In recent years, with the length of high energy permanent magnet material production technology
Foot develops, and the structure of moving-magnetic linear compressor gradually tends to simple, compact, and its efficiency still has greatly improved space.
Utility model content
The purpose of this utility model is the defect and deficiency for prior art, there is provided a kind of simple structure, design are closed
Reason, moving-magnetic linear compressor easy to use.
For achieving the above object, the technical solution adopted in the utility model is：
A kind of moving-magnetic linear compressor, including it is interior yoke, permanent magnet, resonant springs, locating rod, retainer, coil, outer
Yoke, upper plate, cylinder, piston and lower shoe, upper plate are arranged on the top of compressor, and upper plate center upper portion position is arranged
There is cylinder, cylinder bottom is connected with piston, and piston stretches into compressor middle position, and resonant springs are cased with piston, and lower shoe sets
Put in compressor bottom, the left and right sides between upper plate and lower shoe is each provided with 1 outer yoke, the inner side of each outer yoke
Interior yoke is provided with, 2 interior yokes are separately positioned on piston both sides, is provided with forever between the outer yoke and interior yoke per side
Magnet, is provided with coil, retainer is connected with the left of coil, locating rod is installed with retainer on yoke outside right side.
The both sides up and down of outer yoke and interior yoke per side are each provided with a location hole.
Permanent magnet is lamellar cuboid.
Permanent magnet is connected with piston by retainer.
After said structure, this utility model has the beneficial effect that：Linear compressor friction described in the utility model is damaged
Consumption is little, it is possible to achieve oil-free lubrication；Control is flexible, it is possible to achieve stepless tolerance is adjusted, high working efficiency, and has structure letter
The advantages of list, reasonable setting, low manufacture cost.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
Referring to shown in Fig. 1, a kind of moving-magnetic linear compressor, including interior yoke 2, permanent magnet 3, resonant springs 4, locating rod
5th, retainer 6, coil 7, outer yoke 8, upper plate 9, cylinder 10, piston 11 and lower shoe 12, upper plate 9 are arranged on compressor
Top, 9 center upper portion position of upper plate are provided with cylinder 10, and 10 bottom of cylinder is connected with piston 11, and piston 11 stretches into compressor
Middle position, is cased with resonant springs 4 on piston 11, lower shoe 12 is arranged on compressor bottom, between upper plate 9 and lower shoe 12
The left and right sides be each provided with 1 outer yoke 8, the inner side of each outer yoke 8 is provided with 2,2 interior yokes 2 of interior yoke and sets respectively
Put in 11 both sides of piston, permanent magnet 3 is provided between the outer yoke 8 and interior yoke 2 per side, is provided with outside right side on yoke
Coil 7, is connected with retainer 6, locating rod 5 is installed with retainer 6 on the left of coil 7.
The both sides up and down of outer yoke and interior yoke per side are each provided with a location hole 1.
Permanent magnet is lamellar cuboid.
Permanent magnet is connected with piston by retainer.
Compressor stator part is worn by upper and lower base plate and clamps position, subpart, and permanent magnet is lamellar cuboid, is put
Between inside and outside yoke, it is connected with piston by retainer, between retainer and upper and lower base plate, passes through locating rod and linear axis
Hold and be attached, position, to ensure airgap uniformity degree, 2 resonant springs pre-pressings between upper and lower floor and retainer are installed,
When alternating current is passed through in Exciting Windings for Transverse Differential Protection, alternating magnetic field is produced in inside and outside yoke and air gap, what is be placed in air-gap field is permanent
Magnet can be subject to alternation thrust, drive retainer and piston to produce linear reciprocating motion, compressed gas acting, 4 locating rods
Airgap uniformity degree and symmetry of the basic guarantee between Magnet and inside and outside yoke so that the side force that is perpendicularly to the direction of movement compared with
It is little, and mainly act in locating rod, the frictional dissipation being so greatly lowered between cylinder and piston so that the machine is in nothing
Can be with stable operation in the case of oil lubrication.
The above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple
Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model
Spirit and scope, all should cover in the middle of right of the present utility model.
