The oil pump chamber 600 is provided with an oil guide channel 700, which connects the oil pump chamber 600 and the moving parts in the pump body 100. The exhaust pressure of the high-pressure exhaust chamber 500 can drive the oil pump valve assembly 800 to move, so as to pump the lubricating oil in the oil pump chamber 600 to the moving parts through the oil guide channel 700, so as to achieve the purpose of oil return lubrication of the moving parts in the pump body 100, reduce the friction coefficient between the various components of the pump body structure, improve lubrication efficiency, thereby improving the operating efficiency and reliability of the compressor and extending the service life of the compressor.

[0027] In some embodiments of the present invention, the present invention provides a pump body structure, including a pump body 100, a crankshaft 200 disposed inside the pump body, the crankshaft 200 being rotatably disposed within the pump body 100, and a gap 400 being formed between the pump body 100 and the long shaft section of the crankshaft 200. The pump body 100 is provided with a pump oil chamber 600, and the pump oil chamber 600 is provided with an oil guide channel 700, which connects the pump oil chamber 600 and the gap 400. The oil pump chamber 600 is connected to the high-pressure exhaust chamber 500 of the pump body 100, and an oil pump valve assembly 800 is provided between the oil pump chamber 600 and the high-pressure exhaust chamber 500.

[0028] In some embodiments of the present invention described above, a pump body 100 is included, within which a crankshaft 200 is disposed. The crankshaft 200 is rotatably disposed within the pump body 100, and a gap 400 is formed between the pump body 100 and the long shaft section of the crankshaft 200. An oil pumping chamber 600 is disposed on the pump body 100, and the oil pumping chamber 600 is connected to a high-pressure exhaust chamber 500 of the pump body 100. An oil pumping valve assembly 800 is disposed between the oil pumping chamber 600 and the high-pressure exhaust chamber 500, and the high-pressure gas in the high-pressure exhaust chamber 500 can drive the pump body 100. The oil pump valve assembly 800 moves, and the oil pump chamber 600 is provided with an oil guide channel 700. The oil guide channel 700 connects the oil pump chamber 600 and the gap 400. The exhaust pressure of the high-pressure exhaust chamber 500 can drive the oil pump valve assembly 800 to move, so as to pump the lubricating oil in the oil pump chamber 600 to the gap 400 through the oil guide channel 700, so as to achieve the purpose of oil return lubrication for the pump body structural components, reduce the friction coefficient between the various pump body structural components, improve lubrication efficiency, thereby improving the compressor operating efficiency and reliability, and extending the compressor service life.

[0029] It is understood that the high-pressure exhaust chamber 500 is connected to the compression chamber 300. Low-pressure gas is drawn into the compression chamber 300 from the intake port. After being compressed into high-pressure gas by the piston in the compression chamber 300, it can be discharged through the high-pressure exhaust chamber 500. An oil pumping valve assembly 800 is provided between the oil pumping chamber 600 and the high-pressure exhaust chamber 500. After the gas is compressed into high-pressure gas, it flows into the high-pressure exhaust chamber 500. The high-pressure gas can drive the oil pumping valve assembly 800 to move, thereby pumping the lubricating oil in the oil pumping chamber 600 to the gap 400 through the oil guide channel 700.

[0030] It should be noted that the oil guide channel 700 can also guide the lubricating oil to the position where the crankshaft 200 meets the roller.

[0031] In some embodiments of this utility model, the oil pump valve assembly 800 includes an oil pump slider 810 and an elastic element 820. The elastic force of the elastic element 820 drives the oil pump valve block to close the communication port 115 between the oil pump chamber 600 and the high-pressure exhaust chamber 500.

[0032] In some embodiments of the present invention described above, the oil pump valve assembly 800 includes an oil pump slider 810 and an elastic element 820. The oil pump slider 810 is slidably disposed within the oil pump chamber 600. The elastic force of the elastic element 820 drives the oil pump slider 810 to close the communication port 115 between the oil pump chamber 600 and the high-pressure exhaust chamber 500. When the exhaust pressure in the high-pressure exhaust chamber 500 is greater than the elastic force of the elastic element 820, the oil pump slider 810 moves toward the oil pump chamber 600. 810 moves and compresses the gas in the pump oil chamber 600, thereby driving the lubricating oil in the pump oil chamber 600 to be pumped into the gap 400 through the oil guide channel 700, so as to achieve the purpose of oil return lubrication for the pump body structural components, reduce the friction coefficient between the various pump body structural components, improve lubrication efficiency, and thus improve the operating efficiency and reliability of the compressor; when the high-pressure gas is discharged, the elastic force of the elastic element 820 drives the pump oil valve block to reset, thereby closing the passage 115 between the pump oil chamber 600 and the high-pressure exhaust chamber 500.

[0033] It should be noted that by setting the oil pumping chamber 600 in the high-pressure exhaust chamber 500, the high-pressure gas in the high-pressure exhaust chamber 500 is used to complete the oil pumping. This enables automatic circulation of lubricating oil without external force, effectively lubricating the pump body components and improving the compressor's operating efficiency and stability.

When the exhaust pressure in the high-pressure exhaust chamber 500 is greater than the elastic force of the elastic element 820, the oil pump slider 810 can be driven to slide, thereby causing the oil pump slider 810 to slide into the oil pump chamber 600, compressing the gas in the oil pump chamber 600, thereby pumping the lubricating oil into the gap 400, so as to achieve the purpose of returning oil lubrication to the pump body structural components, reducing the friction coefficient between the various pump body structural components, improving lubrication efficiency, and thus improving the operating efficiency and reliability of the compressor.

When the elastic element 820 drives the oil pump slider 810 to reset, a negative pressure is generated in the oil pump chamber 600, which can draw the lubricating oil in the compressor oil sump 900 into the oil pump chamber 600 through the oil inlet check valve 610, thereby completing the oil suction. Through oil suction and oil pumping, the circulation of lubricating oil is realized, so as to achieve the purpose of oil return lubrication for the pump body structural components, reduce the friction coefficient between the various pump body structural components, improve lubrication efficiency, and thus improve the operating efficiency and reliability of the compressor.
