[0004] The utility model provides a kind of compressor weight reduction piston structure, including connecting rod and the cylinder top cover being adapted with the connecting rod;

[0005] The first connecting groove is formed by inwardly recessing the top of the connecting rod, which can reduce the mass of the top of the connecting rod and thereby reduce the vibration in the movement process of the connecting rod.

[0006] The cylinder top cover is provided at the opening of the cylinder sleeve top of the compressor housing where the connecting rod is located, and the top and bottom of the cylinder top cover protrude outward to form a cylinder top cover protrusion that matches the first connecting groove. By providing the cylinder top cover protrusion, the compression ratio of the compressor remains unchanged after the first connecting groove is provided on the connecting rod.

[0007] Preferably, a first through hole is provided at the center of the cylinder top cover.

[0008] Preferably, a second through hole is provided on the cylinder top cover.

[0009] Preferably, a second connecting groove is provided on the side surface of the connecting rod, which can reduce the mass of the connecting rod.

[0010] The compressor weight reduction piston structure has the following advantages:

[0011] 1. By inwardly recessing the top of the connecting rod to form a first connecting groove, the mass of the top of the connecting rod can be reduced, thereby reducing the vibration in the movement process of the connecting rod.

[0012] 2. By providing a cylinder top cover protrusion at the bottom of the cylinder top cover that matches the first connecting groove, the compression ratio of the compressor remains unchanged after the connecting rod is provided with the first connecting groove. Attached Figure Description

[0018] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Reference Figs. 1 to 3 An embodiment of the compressor weight-reducing piston structure of this utility model is proposed:

[0020] A compressor weight-reducing piston structure includes a connecting rod 1 and a cylinder top cover 2 adapted to the connecting rod 1.

[0021] A cylinder liner 3 is mounted on the compressor housing, and a connecting rod 1 is disposed within the cylinder liner 3. The connecting rod 1 includes a connecting rod body 11 at the top, a rotating connector 13 at the end, and a connecting shaft 12 in the middle. The connecting rod body 11 and the rotating connector 13 are connected by the connecting shaft 12, and the connecting rod body 11, the rotating connector 13, and the connecting shaft 12 are integrally formed. A connector connection hole 16 is provided in the middle of the rotating connector 13, and the connecting rod 11 is connected to the output shaft of the motor through the connector connection hole 16, so that the motor can drive the connecting rod 1 to move repeatedly.

[0022] The connecting rod 1 has a second connecting groove 15 on its two opposite sides. The mass of the connecting rod 1 can be reduced by providing the second connecting groove 15. The top of the connecting rod body 11 is recessed inward to form a first connecting groove 14. The mass of the top of the connecting rod 1 can be reduced by providing the first connecting groove 14, thereby reducing the vibration of the connecting rod 1 during movement.
