However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

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

[0030] As Figure 1 shown, the following technical solutions are adopted in this specific embodiment: It includes a high-low cavity splitting component, and the high-low cavity splitting 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. On both outer edges of the cylinder 71, gaps 72 are provided. At the gaps 72, the slider 7 is 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. The hook part of the swing arm 9 is provided with an arc part 92 that is slidably matched with the cylinder 71. On both inner sides of the upper and lower ends of the hook part of the swing arm 9, a first notch 93 is provided. In the first notch 93, the swing arm 9 is fixedly connected to the lower bearing cover 6 and the upper bearing cover 8 on one side of the cylinder 71 through a limit pin and a bolt.

[0031] It also includes a cavity 3 and a moving disk 5. The cavity 3 has a hollow cavity, and the hollow cavity is sleeved on the outer wall of the moving disk 5. On the side wall of the hollow cavity, a special - shaped groove is provided. At both ends of the special - shaped groove, an arc groove one 31 and an arc groove two 32 are provided respectively.

The arc groove three 51 is rotationally clamped with the cylinder 71 on the other side. On both inner sides of the upper and lower ends of the arc groove three 51, a second notch 52 is provided. The second notch 52 is fixedly connected to the lower bearing cover 6 and the upper bearing cover 8 on the cylinder 71 on the other side through a limit pin and a bolt. A round hole is provided at the center of the cylinder 91, and a shaft pin is installed in the round hole. Both 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 rotationally fitted with the bearing cover, and the outer wall of the cylinder 71 is rotationally fitted with the arc-shaped groove three 51 and the arc portion 92. The slider 7 composed of two cylinders 71 effectively rotationally connects the moving disk 5 and the swing arm 9, and the cylinder 71 abuts and rotates with the arc-shaped groove three 51 and the arc portion 92, so that the mating parts are rotationally sealed, effectively ensuring the sealing of the high and low pressure chambers, avoiding gaps at the mating parts and preventing air leakage.

[0034] The cylinder 91 on the swing arm 9 abuts and rotates with the arc-shaped groove one 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. The vertical grooves opened on the side walls of the arc-shaped groove one 31, the arc-shaped groove three 51 and the arc portion 92 reduce the contact area between the mating parts, reduce the friction between the mating parts, have a stable structure, small friction between each other, low noise, and reduce the energy consumption due to friction. It not only saves costs and protects the environment, but also effectively improves 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 rotationally connected to the bottom cover 2, the moving disk 5 and the upper cover 10 in sequence through bearings, and 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 sealed inside the cavity 3; an air outlet hole is opened on the surface of the upper cover 10, and an air inlet hole is opened on the surface of the bottom cover 2.

[0036] A plurality of 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 eccentric grooves 411 and lower eccentric grooves 412 that are eccentrically arranged with the bearing bracket 41 are respectively opened on the upper and lower end surfaces of the bearing bracket 41. Bearings are rotationally clamped on the upper eccentric grooves 411 and the lower eccentric grooves 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 opened 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 opened on the bottom cover 2, and the aperture of the limiting hole 21 is larger than the outer diameter of the pin shaft 42, so that the pin shaft 42 has 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 fitted 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 limiting hole 21 on the bottom cover 2. When the eccentric drive shaft 1 drives the moving disk 5 to rotate eccentrically, the self-rotation limiting component 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 limiting hole 21 on the bottom cover 2 in its movement range, it drives the moving disk to swing circularly within a certain angle around the eccentric drive shaft 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 due to 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 partitioning component and the self-rotation limiting component, so the specific working principle of the compressor will not be elaborated here.
