a drive motor for driving the pump body, the drive motor having a middle channel and an edge channel and

the flow guide structure is arranged between the pump body and the driving motor and matched with the driving motor and the pump body to form an exhaust space, the exhaust space is surrounded by the flow guide structure, the exhaust port is communicated with the middle channel to form the exhaust space, and the edge channel is isolated outside the exhaust space by the flow guide structure.

2. The compressor of claim 1, wherein the flow directing structure comprises:

a motor insulation plate disposed on the driving motor, the motor insulation plate having an insulation plate extension portion extending toward the pump body;

the silencing extension plate is arranged on the main silencer of the pump body and is in butt fit with the motor insulation plate.

3. The compressor of claim 2, wherein the insulator plate extension and the muffler extension plate are in nested engagement.

4. The compressor of claim 2, wherein the insulation plate extension is formed in a divergent trumpet shape, and the sound attenuation extension plate is inserted and extended into the insulation plate extension; or

The noise elimination extension plate is formed into a gradually expanding horn shape, and the insulation plate extension is inserted and extended to the noise elimination extension plate.

5. The compressor of claim 2, wherein at least one of the insulation plate extension and the sound attenuation extension plate is configured as an elastically deformable elastic plate, and the insulation plate extension forms an interference fit with the sound attenuation extension plate.

6. The compressor of claim 2, wherein the insulation plate extension is formed in a divergent trumpet shape, and the sound attenuation extension plate extends from an outer peripheral edge of the main sound attenuator in an axial direction of the driving motor in a direction approaching the insulation plate extension.

7. The compressor of claim 6, wherein said sound attenuation extension plate spans a plane in which said discharge port on said main muffler is located.

8. The compressor of claim 7, wherein the sound attenuation extension plate is formed integrally with the main muffler, and the sound attenuation extension plate is located inside the insulation plate extension.

9. The compressor of claim 1, wherein the flow directing structure comprises:

the motor insulation board is arranged on the driving motor and provided with an insulation board extension portion, and the insulation board extension portion faces the pump body and extends to abut against the pump body.

10. The compressor of claim 9, wherein an end of the insulation plate extension remote from the drive motor abuts against a main muffler of the pump body.

11. The compressor of claim 1, wherein the flow directing structure comprises:

the silencing extension plate is arranged on a main silencer of the pump body, extends towards the driving motor and abuts against a fixed part of the driving motor.
