Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this The scope of utility model protection.

The compressor that this utility model embodiment provides, including: housing 1, it is respectively positioned on the motor in housing 1 And pump body structure；Wherein, motor includes: stator 3, rotor 6, magnet steel 7, pump body structure includes method The parts such as orchid 9, cylinder 10, bent axle 4.

The cylinder 10 of above-mentioned pump body structure is fixedly linked with the rotor 6 of motor, the bent axle of pump body structure 4 with Housing 1 is fixedly linked.It should be noted that the rotor 6 of motor is rotationally.

In above-mentioned compressor, bent axle 4 is fixedly linked with housing 1, and specifically, bent axle 4 is straight with housing 1 Connect and be fixedly linked or bent axle 4 is fixedly linked indirectly with housing 1；Wherein, between bent axle 4 and housing 1 Connect and be fixedly linked, i.e. bent axle 4 is fixedly linked with housing 1 by the miscellaneous part in housing 1.For song How axle 4 is fixedly linked with housing 1, and this is not limited by this utility model embodiment.

The compressor that this utility model embodiment provides, owing to rotor 6 is fixedly linked with cylinder 10, bent axle 4 are fixedly linked with housing 1, then, in compression process, rotor 6 band dynamic air cylinder 10 rotates, and bent axle 4 Maintaining static, realize compression by the rotation of cylinder 10, relatively prior art uses crank rotation to realize compression Compare, effectively increase the rotary inertia of rotatable parts, improve the stationarity of compressor low-frequency operation.

It should be noted that within the compressor, when cylinder 10 rotates, it is positioned at the upper method of cylinder 10 both sides Orchid 9, lower flange (central dividing plate 11) need to rotate with cylinder 10, to ensure cylinder 10 air-breathing And aerofluxus.Therefore, rotary inertia when cylinder 10 rotates is far longer than rotary inertia when bent axle 4 rotates.

There is various structures in the motor of above-mentioned compressor, can be designed according to actual needs.Specifically, This utility model embodiment provides two kinds of electric machine structures.

As Figure 1-3, in the compressor that this utility model embodiment one provides, motor is external rotor electric machine.
