Description

Technical Field

[0001] This invention belongs to the field of compressor technology, specifically relating to an active lubrication structure for compressor pistons. Background Technology

[0002] A compressor is a machine that converts mechanical energy into potential energy. In a reciprocating compressor, the crankshaft rotates, driven by an external motor rotor or other torque, which in turn drives the piston in reciprocating motion, thus converting mechanical energy into potential energy. Compressor pistons are prone to wear, and lubricating oil may not easily reach the friction pairs. Furthermore, compressors suffer from the problem that lubricating oil cannot adequately lubricate the piston friction pairs during initial startup. Summary of the Invention

[0003] This invention provides an active lubrication structure for a compressor piston, and the technical problem to be solved is: to solve the problem that the lubricating oil cannot lubricate in time when the compressor is first started in the prior art.

[0004] To solve the above technical problems, the present invention provides an active lubrication structure for a compressor piston, including a compressor body, an oil pan at the bottom of the compressor body, and a crankshaft inside the compressor body. An oil inlet passage is provided at the upper end of the compressor body near the cylinder. A groove is provided inside the oil inlet passage on the side near the cylinder, and a sponge block is placed inside the groove. A sliding opening is provided through the bottom of the groove on the side near the cylinder, and a pressing block is slidably placed inside the sliding opening. The top of the pressing block and the bottom of the sponge block are in close contact. A through hole is provided through the groove on the side near the cylinder, and a partition is integrally formed at the upper end of the groove, with a through hole extending through the partition.

[0005] Beneficial effects: The compressor of this invention has a groove on the side of the cylinder, a sponge block is placed in the groove, and a compression block is slidably placed on the bottom side of the groove. When the compressor starts, the piston pushes the compression block to slide under the action of friction, compressing the sponge block and squeezing out the lubricating oil in the sponge block through the through hole, which can lubricate the piston and reduce the wear between the piston and the cylinder when the compressor starts.

[0009] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below.

[0010] The present invention proposes an active lubrication structure for a compressor piston, comprising a compressor body 1, an oil pan 3 at the bottom of the compressor body 1 for holding lubricating oil, a crankshaft 2 inside the compressor body 1, an oil inlet 4 at the upper end of the compressor body 1 near the cylinder, a groove 5 inside the oil inlet 4 near the cylinder, a sponge block 6 inside the groove 5, a sliding port 8 penetrating through the bottom of the groove 5 near the cylinder, a pressing block 7 slidingly inside the sliding port 8, the top of the pressing block 7 being in close contact with the bottom of the sponge block 6, a through hole 9 penetrating through the groove 5 near the cylinder, and a partition 10 integrally formed at the upper end of the groove 5 above the sponge block 6, the partition 10 having a through hole 11 penetrating through.

[0011] The working process of the above structure is explained in detail below. During operation, the crankshaft 2 works, which throws the lubricating oil in the oil pan 3 upward, forming splash lubrication. Some of the lubricating oil enters the lubricating oil inlet 4 and falls into the groove 5, where it is collected. When the compressor starts again, the piston slides, and under the action of friction, it drives the extrusion block 7 to slide upward. When the extrusion block 7 slides upward, it squeezes the sponge block 6. When the sponge block 6 is compressed, the lubricating oil in it is squeezed out through the through hole 9, which lubricates the piston and cylinder.

[0012] Specifically, the height of the sliding opening 8 is greater than the thickness of the extrusion block 7.

[0013] The partition 10 is positioned near the upper end of the groove 5. When the extrusion block 7 moves upward, the sponge block 6 is compressed between the partition 10 and the extrusion block 7, squeezing out the lubricating oil. The partition 10 is near the upper end of the groove 5, and after the sponge block 6 has fully absorbed the lubricating oil, it stores more lubricating oil for later use.

[0014] Furthermore, the lubricating oil inlet channel 4 is inclined from bottom to top towards the groove 5, so that when the lubricating oil is thrown upward from the oil pan 3, it is guided by the lubricating oil inlet channel 4 and moves towards the groove 5, making it easier to enter the groove 5.

[0015] In the description of this invention, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0016] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
