Specific embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 1 to 3, the utility model includes
Motor 3, handpiece of air compressor 7, the appearance of described motor 3 are enclosed with one layer of metal plate casing 2, in the appearance and metal plate of the motor 3
Air flue 4 is provided between casing 2；The motor shaft afterbody of described motor 3 is provided with fan blade 1, and fan housing 9 is provided with the side of fan blade 1, should
The side of fan housing 9 is the air intake passage of fan blade 1, and opposite side is inlayed with metal plate casing 2, and another effect of fan housing 9 is as far as possible
Limit the leakage of pre- pressurized air.The motor shaft front end of the motor 3 is connected by shaft coupling with the drive shaft of handpiece of air compressor 7
Connect；The shell wall of described metal plate casing 2 is provided with a concentration gas outlet 5, and the concentration gas outlet 5 enters with handpiece of air compressor 7
Connected by pipeline 10 between mouthful, air filtering core device 6 is installed on the pipeline 10, the lower section of the handpiece of air compressor 7 is provided with compression sky
Gas gas outlet 8.
Described metal plate casing 2 is a cylinder-like structure, and the material used by it is cold-reduced sheet or stainless steel materials.
The described structure of fan blade 1 is centrifugation blade or axial-flow leaf.
Operation principle of the present utility model is：Compressed air to using motor afterbody centrifugation blade (or axial-flow leaf etc.)
About 0.105-0.14 MPas of pressure, the air after supercharging is flowed to by the air flue 4 that radiates concentrates gas outlet 5, when by motor 3
Take away the heat of motor, pressurized air by air filtering core device 6 to handpiece of air compressor 7, through second compression again reach goal pressure from
Flow out air compressor machine gas outlet 8.
For air compressor machine, pre- pressurized energy is more favourable closer to goal pressure, but the pressure of pre- increasing is in view of motor
Among power, supercharging can improve the temperature of air, so the pre- pressurized energy of this patent should not cross 0.15 MPa, so be dissipated including motor
Interior within 10 degree, the temperature of motor internal is also in the reasonable scope for the temperature total value that heat and compressed air are lifted.
The widely accepted Efficient Compression air manner of air compressor machine two stages of compression, but this structure compressor cost
Far above single stage compress, organization plan of the present utility model can realize the inexpensive comprehensive utilization of energy of motor to realize two
Level compression or three stage compression (can realize three stage compression using this patent before former two stages of compression).
The utility model is not limited to above-mentioned implementation method, all no matter constitute making any change in its shape or material
It, using structure design provided by the utility model, is all a kind of deformation of the present utility model to be, is considered as new in this practicality
Within type protection domain.
