DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be described below through specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0029] Here, it should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the drawings, while other details less related to the present invention are omitted.

[0030] As Figures 1-8 shown, the present specific embodiment adopts the following technical solution: It includes a high-low cavity segmentation component, and the high-low cavity segmentation component includes a lower bearing cover 6, a slider 7, an upper bearing cover 8, and a swing arm 9. The slider 7 is formed by connecting two cylinders 71 into an "8" - shaped structure. Notches 72 are provided on the outer edges of both sides of the cylinder 71. The notches 72 are slidably connected to the lower bearing cover 6 and the upper bearing cover 8 through bearings respectively. The swing arm 9 is of a hook - type structure. The hanging part of the swing arm 9 is a cylinder 91. An arc part 92 slidably matched with the cylinder 71 is provided on the hook part of the swing arm 9. Notches one 93 are provided on the inner sides of the upper and lower ends of the hook part of the swing arm 9. The notches one 93 are fixedly connected to the lower bearing cover 6 and the upper bearing cover 8 on one side of the cylinder 71 through limit pins and bolts.

[0031] It also includes a cavity 3 and a moving disk 5. The cavity 3 is provided with a hollow cavity. The hollow cavity is sleeved on the outer wall of the moving disk 5. A special - shaped groove is provided on the side wall of the hollow cavity. Arc grooves one 31 and arc grooves two 32 are respectively provided at both ends of the special - shaped groove. The arc groove one 31 is rotationally clamped with the cylinder 91. The hook part of the swing arm 9 is located in the arc groove two 32. An arc groove three 51 is provided on the moving disk 5. The arc groove three 51 is rotationally clamped with the cylinder 71 on the other side. Notches two 52 are provided on the inner sides of the upper and lower ends of the arc groove three 51. The notches two 52 are fixedly connected to the lower bearing cover 6 and the upper bearing cover 8 on the cylinder 71 on the other side through limit pins and bolts. A round hole is provided at the center of the cylinder 91. A shaft pin is installed in the round hole. The two ends of the shaft pin are rotationally connected to the bottom cover 2 and the upper cover 10 through bearings respectively.

[0032] A plurality of vertically - distributed vertical grooves are provided on the side walls of the arc groove one 31, the arc groove three 51, and the arc part 92.

[0033] In the embodiment: The slider 7 has an "8"-shaped cylinder structure. The inner side of the cylinder 71 is rotatably fitted with the bearing cover, and the outer wall of the cylinder 71 is rotatably fitted with the third arc-shaped groove 51 and the arc portion 92. The slider 7 composed of two cylinders 71 effectively rotatably connects the moving disk 5 and the swing arm 9, and the cylinder 71 abuts and rotates with the third arc-shaped groove 51 and the arc portion 92, enabling sealed rotation at the mating parts, effectively ensuring the sealing performance of the high and low pressure cavities, avoiding gaps at the mating parts and preventing air leakage.

[0034] The cylinder 91 on the swing arm 9 abuts and rotates with the first arc-shaped groove 31 on the cavity 3, thereby dividing the cavity seal between the cavity 3 and the moving disk 5, achieving the function of dividing the high and low cavities. Vertical grooves are provided on the side walls of the first arc-shaped groove 31, the third arc-shaped groove 51, and the arc portion 92, reducing the contact area between the mating parts, reducing the friction between the mating parts. Its structure is stable, the friction between each other is small, the noise is small, reducing the energy consumption consumed by friction. This not only saves costs and protects the environment, but also effectively extends the service life of the compressor.

[0035] It further includes an eccentric drive shaft 1, a bottom cover 2, and an upper cover 10; the eccentric drive shaft 9 is rotatably connected to the bottom cover 2, the moving disk 5, and the upper cover 10 in sequence through bearings. The bottom cover 2, the cavity 3, and the upper cover 10 are fixedly connected by positioning pins and bolts, and the moving disk 5 is hermetically and movably sealed inside the cavity 3; an air outlet hole is provided on the surface of the upper cover 10, and an air inlet hole is provided on the surface of the bottom cover 2.

[0036] Several self-rotation limiting components 4 are provided between the bottom cover 2 and the moving disk 5. The self-rotation limiting component 4 includes a bearing bracket 41, a bearing, and a pin shaft 42. Upper and lower eccentric grooves 411 and 412 that are eccentrically arranged with respect to the bearing bracket 41 are respectively provided on the upper and lower end surfaces of the bearing bracket 41. Bearings are rotatably clamped on the upper and lower eccentric grooves 411 and 412, and a pin shaft 42 is installed in the central hole of the bearing; the number of the self-rotation limiting components 4 is 3.

[0037] A groove 53 for installing the self-rotation limiting component 4 is provided on the moving disk 5, and an assembly hole 54 for cooperating with the pin shaft 42 is provided on the bottom wall of the groove 53; a limiting hole 21 for restricting the movement path of the pin shaft 42 is provided on the bottom cover 2, and the aperture of the limiting hole 21 is larger than the outer diameter of the pin shaft 42, enabling the pin shaft 42 to have a certain rotation space in the limiting hole 21.

[0038] In the embodiment: The pin shaft 42 at one end of the bearing bracket 41 is engaged with the assembly hole 54 on the moving disk 5, and the pin shaft 42 at the other end of the bearing bracket 41 is inserted into the limit hole 21 on the bottom cover 2. When the eccentric drive shaft 1 drives the moving disk 5 to perform eccentric rotation, the self-rotation limit assembly 4 on the moving disk 5 will rotate with the moving disk 5. Since the pin shaft 42 at the upper end is restricted by the limit hole 21 on the bottom cover 2 in its movement range, it drives the moving disk to swing in a cycle within a certain angle with the eccentric drive shaft as the axis through the pin shaft 42 at the lower end, thereby realizing the limitation of the self-rotation angle of the moving disk 5; its structure is stable, the friction between each other is small, the noise is small, the energy consumption consumed by friction is reduced, not only the cost is saved, the environment is protected, but also the service life of the compressor is effectively improved.

This application only improves the structures of the high and low cavity dividing assembly and the self-rotation limit assembly, so the specific working principle of the compressor will not be elaborated here.
