252, the second air duct 251 and exhaust outlet.
The cooling principle of the scroll air compressor provided by the present application is illustrated below with reference to Fig. 4.
Wherein blower 3 is set in the shaft body 111 of the drive shaft 11, is rotated synchronously under the drive of shaft body 111,
Blower 3 is located in the accommodation space inside pump head 2, and blower 3 described herein can be that centrifugal blower is also possible to axis stream
Blower cross flow fan etc.；When driving motor 1 operates, blower 3 is rotated synchronously with shaft body 111, and cold wind is by front shroud
Second recirculation hole 221 enters in connection cavity 223 on first air inlet 211 and shell 22, and cold wind is by wind in connection cavity 223
Machine 3 blows to orbiter 24, by the first recirculation hole 261 on drive disk, enters the first air duct inside orbiter 24
In 242, entered in transitional cavity 222 after radiating to orbiter 24 by the first air outlet 243, then via transition
The second air inlet 252 that cavity 222 enters fixed scroll 25 cools down fixed scroll 25, to 25 cooling of fixed scroll
By the outside for being expelled to shell 22 by exhaust outlet, and then complete entire cooling procedure.
Dynamic and static 25 compressed air of scroll plate can be realized using scroll air compressor provided by the present application, reach oil-free
The functional requirement of screw compressor.For scroll air compressor provided by the present application without air ducting, complete machine structure is succinct, subtracts simultaneously
The small package size of air compressor machine, makes air compressor machine miniaturization more compact, while reducing processing and manufacturing cost；Cold wind directly transports
To the scroll plate back side, No leakage and flow losses improve radiating efficiency；Muting function is improved after removal wind guiding component, is reduced
Vibration.
The working principle of scroll air compressor addressed below.
Scroll air compressor includes driving motor 1, mounting base 4 and pump head 2, the driving motor 1 and the pump head 2
It is each attached on the mounting base 4；Orbiter 24,25 driving plate 26 of fixed scroll and anti-rotation crank throw are equipped in pump head 2
Component 27, the driving motor 1 are sequentially connected with drive shaft 11, and drive shaft 11 includes shaft body 111 and is eccentrically set on described
Cam pin 112 in shaft body 111；The pump head 2 includes drive end bearing bracket 21, shell 22 and rear end cap 23, the fixed scroll 25
It is fixed on shell 22, the anti-rotation crank assembly 27 is identical as the eccentricity of the drive shaft 11, described dynamic for limiting
24 rotation of scroll plate makes the orbiter 24 be merely able to do eccentric rotary motion under the drive of drive shaft 11；Optionally, exist
It is equipped with the anti-rotation crank assembly 27 of multiple groups in pump head 2, can guarantee the equilibrium that do not stress in pump head 2 in this way, on the rear end cap 23
Equipped with air inlet pipe, the compression chamber formed between the air inlet pipe and the fixed scroll 25 and orbiter 24 is connected to.It is vortexed
In compressor operation, by driving motor 1 by drive shaft 11 drive orbiter 24 do revolution translation, orbiter 24 with
The intermeshing of fixed scroll 25 is to form crescent compression chamber, as air enters compression chamber, dynamic vortex by air intake duct 224
The work of disk 24 continues revolution and is translatable and remains good meshing state, and compression chamber is constantly elapsed to center, and volume constantly reduces,
Cavity internal pressure constantly rises；When compression reaches predetermined compression ratio, pressure-air is passed through by the center exhaust outlet of fixed scroll 25
Exhaust valve 225 is discharged.
