A kind of pump body structure, comprise upper flange, lower flange, cylinder, outlet valve and baffler, described upper flange and described lower flange are positioned at two end faces of described cylinder, described upper flange is provided with relief opening, waist shaped hole and valve seat mounting groove, described sound insulator and described upper flange surround sound insulation cavity, the valve seat of described outlet valve is arranged on described valve seat mounting groove, the valve block of described outlet valve is relative with described relief opening, and described outlet valve is positioned at described sound insulation cavity, described upper flange is provided with auxiliary exhaust mouth, described auxiliary exhaust mouth is communicated with described cylinder and described waist shaped hole.
Preferably, in said pump body structure, described auxiliary exhaust mouth is communicated with described valve seat mounting groove and described waist shaped hole.
Preferably, in said pump body structure, the cross section of described auxiliary exhaust mouth is triangle.
Preferably, in said pump body structure, the cross section of described auxiliary exhaust mouth is rectangle.
Preferably, in said pump body structure, the cross section of described auxiliary exhaust mouth is circular arc.
Preferably, in said pump body structure, the cross section of described auxiliary exhaust mouth is trapezoidal.
As can be seen from such scheme, when adopting the pump body structure refrigerant in the utility model to flow through the narrow passage of baffler both sides, part refrigerant is still discharged by exhaust port, the refrigerant of moiety aggregation at the valve seat place of outlet valve then can be discharged by auxiliary exhaust mouth in time, thus reduce the eddy current of local space, reduce exhaust resistance, add refrigerant discharge flow rate.
In order to realize above-mentioned second object, the utility model additionally provides a kind of compressor, comprises pump body structure, and described pump body structure is the pump body structure described in above-mentioned arbitrary technological scheme.Because said pump body structure has above-mentioned effect, the compressor comprising this pump body structure also has corresponding effect, repeats no more herein.

Embodiment
Core of the present utility model is to provide a kind of pump body structure, to reduce the eddy current of local space; Another core of the present utility model is to provide a kind of compressor.
Below, with reference to accompanying drawing, embodiment is described.In addition, the embodiment shown in below does not play any restriction effect to the model utility content described in claim.In addition, the solution that the full content of the formation below represented by embodiment is not limited to as the model utility described in claim is necessary.
Refer to Fig. 4 to Fig. 6, a kind of pump body structure, comprise upper flange 1, lower flange 2, cylinder 3, outlet valve 5 and baffler 4, upper flange 1 and lower flange 2 are positioned at two end faces of cylinder 3, upper flange 1 is provided with relief opening 11, waist shaped hole and valve seat mounting groove 12, sound insulator and upper flange 1 surround sound insulation cavity, the valve seat of outlet valve 5 is arranged on valve seat mounting groove 12, the valve block of outlet valve 5 is relative with relief opening 11, and outlet valve 5 is positioned at sound insulation cavity, upper flange 1 is provided with auxiliary exhaust mouth 13, and auxiliary exhaust mouth 13 is communicated with cylinder 3 and waist shaped hole.
When adopting the pump body structure refrigerant in the utility model to flow through the narrow passage of baffler 4 both sides, part refrigerant is still discharged by exhaust port, the refrigerant of moiety aggregation at the valve seat place of outlet valve 5 then can be discharged by auxiliary exhaust mouth 13 in time, thus reduce the eddy current of local space, reduce exhaust resistance, add refrigerant discharge flow rate.
