The utility model is described in detail below with reference to specific examples:
as shown in fig. 1, 2 and 3, the present invention provides a compressor pump body structure, including:

the sliding block 30 is slidably arranged on the upper flange 10 and is provided with a first working position for isolating the exhaust hole 11 from the inner cavity of the cylinder body 20 and a second working position for communicating the exhaust hole 11 with the inner cavity of the cylinder body 20.
As shown in fig. 2, the upper flange 10 is provided with a sliding hole 12 penetrating through the upper flange 10 in a direction parallel to the axial direction of the upper flange 10, and a position of an inner wall of the sliding hole 12 away from a fitting surface of the upper flange 10 for fitting with the cylinder 20 (i.e., a surface of the upper flange 10 contacting with the cylinder 20) is provided with a limiting protrusion 121, and preferably, in the present embodiment, the limiting protrusion 121 is an annular structure and is provided at an end of the sliding hole 12 to reduce an inner diameter of the end of the sliding hole 12, thereby limiting the slider 30. Further preferably, the axes of the slide hole 12 and the exhaust hole 11 are both parallel to the axis of the upper flange 10, and the slide hole 12 and the exhaust hole 11 communicate on the fitting surface of the upper flange 10.

Further, the depth of the exhaust groove 13 is L4, that is, the axial length of the exhaust groove 13 is L4, and the axial length of the exhaust hole 11 is L1, that is, the axial length of the exhaust hole 11 is L1, wherein L4/L1 is more than 0.2 and less than 0.6, so as to ensure effective exhaust and achieve the desired effect, and in addition, to prevent the unfavorable phenomena of reduced bearing capacity of parts and the like caused by the excessively large axial dimension of the exhaust groove 13. Furthermore, the exhaust groove 13 should be smoothly connected with the bottom wall and the side wall of the slide hole 12, the exhaust hole 11, etc. as much as possible, so as to prevent stress concentration between the bottom wall and the side wall, prevent the occurrence of the alternate fracture phenomenon at the intersection of the bottom wall and the side wall, and prolong the service life of the compressor.

The exhaust silencing principle is that impedance is added on a sound channel to attenuate sound with a part of frequency, and the exhaust flow channel also has a sectional area for changing gas flow, thereby achieving the aim of silencing.

As shown in fig. 3, the upper end of the inner peripheral wall of the cylinder 20 is provided with an exhaust slit 21, and when the slider 30 is located at the first operating position, the stopper 32 is fitted into the exhaust slit 21 to close the exhaust slit 21.

The exhaust process of the pump body structure of the compressor comprises the following steps:
when the compressor needs to exhaust, as shown in fig. 6 and 7, the high-pressure gas in the cylinder 20 acts on the end surface of the first end of the slider 30 and pushes the slider 30 to slide upwards to the second working position, as shown in fig. 6, the stopper 32 is separated from the exhaust notch 21 of the cylinder 20, the exhaust channel is opened, and the gas is exhausted through the exhaust notch 21, the communication groove and the exhaust hole. After the exhaust is completed, the sliding block 30 slides downwards under the action of the gravity of the sliding block, and the sliding hole 12 is a through hole and can be communicated with a backpressure cavity of the compressor, so that the sliding block 30 can smoothly slide up and down in the sliding hole 12, and under the action of the gas pressure in the backpressure cavity, the sliding block 30 is located at a first working position when the exhaust is not performed, as shown in fig. 7, the stop block 32 is tightly pressed in the exhaust notch 21 to completely seal the exhaust notch, block an exhaust channel and avoid gas leakage.
