Optionally, compressor 1000 further includes a bearing disposed on frame 2002 and between crankshaft 300 and frame 2002. For example, the frame 2002 is provided with the above-mentioned crank hole 20021, the bearing is located in the crank hole 20021, and the crankshaft 300 is connected to the other end of the connecting rod through the shaft hole.

In the prior art, because the crankshaft 300, the connecting rod, the piston and the main frame 200 are installed and connected, in order to avoid cylinder ejection during actual installation, relative distances between the piston and the cylinder surface of the cylinder 2001, between the crankshaft 300 and the frame 2002 and between the crankshaft 300 and the cylinder 2001 need to be ensured, however, because the crankshaft 300, the connecting rod, the piston and the main frame 200 have dimensional tolerances, and because the cylinder 2001 and the frame 2002 of the main frame 200 are integrated, the relative distances need to be adjusted by using gaskets during actual installation.

In contrast, in the present application, the cylinder 2001 and the frame 2002 are formed as separate processing molding members, and it should be explained here that the cylinder 2001 and the frame 2002 can be separately processed, that is, the cylinder 2001 and the frame 2002 are assembled after being separately manufactured.

Specifically, since the cylinder 2001 and the frame 2002 are formed as separate molded parts, during the assembly process of the compressor 1000, the cylinder 2001 may be pre-mounted on the frame 2002 (for example, the cylinder 2001 and the frame 2002 are connected by a fastener bolt or a snap, etc.), and at this time, the cylinder 2001 is loose with respect to the frame 2002, the position between the cylinder 2001 and the frame 2002 may be adjusted to some extent, and the relative positional relationship between the piston and the cylinder 2001, between the crankshaft 300 and the frame 2002, and between the crankshaft 300 and the cylinder 2001, etc. may be ensured by fine-adjusting the position of the cylinder 2001, and then the cylinder 2001 and the frame 2002 are fixed (for example, locking the above bolt). Therefore, the relative position of the gasket is not required to be adjusted, the gasket is prevented from being stored on a production line to facilitate adjustment, the gasket is prevented from being confused, field management is facilitated, the quality risk of the compressor 1000 caused by the gasket in a wrong way can be avoided, the number of parts is reduced, the cost is reduced, and the installation is convenient.

This is advantageous in improving the reliability of the connection between the intake valve plate 4004 and the valve plate 400 and between the exhaust valve plate 4002 and the valve plate 400.

In other embodiments, at least one of the suction valve plate 4004 and the discharge valve plate 4002 is coupled to the valve plate 400 by laser welding, infrared welding, or ultrasonic welding. It should be understood that the suction valve plate 4004 and the discharge valve plate 4002 may be connected to the valve plate 400 by other means as long as the connection strength therebetween can be ensured.

Specifically, as shown in fig. 16, a mounting groove 4005 for mounting the suction valve plate 4004 is provided on the valve plate 400, that is, a mounting groove 4005 is provided on a surface of the valve plate 400 facing the cylinder 2001, and the suction valve plate 4004 can be mounted to the mounting groove 4005, thereby being beneficial to reducing the volume of the whole of the suction valve plate 4004 and the valve plate 400, and simultaneously being beneficial to saving the material of the valve plate 400 and reducing the material cost.

In some embodiments of the present invention, the compressor 1000 further comprises a suction and exhaust muffler assembly 100. As shown in fig. 1 to 9, the suction muffler assembly 100 may include a muffler 10 and an exhaust pipe 20. The muffler 10 is provided to the valve plate 400, and a muffler chamber is formed in the muffler 10, and a partition plate 1013 is provided in the muffler chamber to partition the muffler chamber into a suction muffler chamber 101 and an exhaust muffler chamber 102, that is, the suction muffler chamber 101 and the exhaust muffler chamber 102 are provided in the muffler 10 to be spaced apart from each other.

The second seal 600 is a flexible member. Specifically, the second seal member 600 is a rubber member, such as a fluororubber member or a hydrogenated nitrile rubber member. Therefore, the sealing effect is good, the high-temperature resistance is strong, and the cost is low.

Specifically, the sealing member between the muffler 10 and the valve plate 400 is generally an asbestos-free gasket, the asbestos-free gasket is generally made of an asbestos-free material, the strength and rigidity of the asbestos-free material are high, the elastic deformation is small, and the sealing function can be achieved, but when the valve plate 400 and the muffler 10 are fastened by bolts, the required locking torque is large, the risk of deformation of the muffler 10 and the valve plate 400 may be increased, and the problem of leakage is caused by poor sealing of the asbestos-free gasket due to the attenuation of the torque of the bolts and the loosening of the bolts after long-term use of the structure.

Relatively speaking, in this application, because second sealing member 600 is the rubber spare, in particular, second sealing member 600 is fluororubber spare or hydrogenation butadiene acrylonitrile rubber spare, elastic deformation ability is good, need not bolt fastening muffler 10 and valve plate 400 like this, only utilize the jump ring just can realize the fastening effect, it is sealed effectual, bolt torque attenuation has been avoided, the non-asbestos gasket that the bolt becomes flexible leads to is sealed badly, and then avoid revealing the problem, still be favorable to avoiding simultaneously because of the problem of the deformation of valve plate 400 and muffler 10 that bolt fastening brought, bring probably for muffler 10 adopts plastic material, also bring probably for thinning valve plate 400.

Specifically, the second seal groove 108 includes two portions, that is, an annular seal groove 1081 and a connection groove 1082, the annular seal groove 1081 surrounds the suction outlet 1012 and the discharge inlet 1021 and corresponds to the seal ring 6001 described above, the connection groove 1082 is located in the annular seal groove 1081 and both ends of the connection groove 1082 communicate with the annular seal groove 1081, the connection groove 1082 corresponds to the seal strip 6002, the seal ring 6001 may be located partially in the annular seal groove 1081 and the remaining portion exceeds the open port of the annular seal groove 1081 and is located between the muffler 10 and the valve plate 400, the seal strip 6002 may be located partially in the connection groove 1082 and the remaining portion exceeds the open port of the connection groove 1082 and is located between the muffler 10 and the valve plate 400, so that the second sealing groove 108 can limit the second sealing member 600, avoid the leakage problem caused by the displacement of the second sealing member 600, while the second seal groove 108 may also function to control the amount of deformation of the second seal 600.

Specifically, a limiting portion 109 is disposed at the exhaust inlet 1021, and the limiting portion 109 is used for limiting the lift distance of the exhaust valve plate 4002. Therefore, the limiting portion 109 can function as a limiting lift device, so that an additional limiting lift device is not required, the number of parts is reduced, the cost is reduced, and the structure of the compressor 1000 is simplified.

Alternatively, the stopper portion 109 is integrally provided on the muffler 10. For example, the muffler 10 is embedded in a mold, and the stopper 109 is integrally injection-molded on the muffler 10. As another example, the silencer 10 with the retainer 109 is injection molded directly through a mold. Therefore, the production process is simplified, the production cost is reduced, and the connection strength between the limiting part 109 and the silencer 10 is improved.
