Protective housing and compressor
By designing an annular region and an isolation chamber between the inner and outer casings of the compressor to form a double-sealed structure and injecting refrigerant inhibitors, the problem of refrigerant leakage caused by unreliable sealing is solved, improving sealing performance and safety, reducing the risk of combustion and explosion, and improving energy efficiency.

AI Technical Summary
Technical Problem
The existing compressor's sealing structure is unreliable and cannot effectively prevent the leakage of flammable refrigerants such as R290, leading to safety hazards.
Method used
A split-shell structure is designed, including an annular region between an inner shell and an outer shell to form a double-sealed structure. A refrigerant inhibitor is injected into the annular region to buffer refrigerant leakage and reduce the risk of direct leakage to the outside.
Benefits of technology
It improves the compressor's sealing and safety, reduces the scale of refrigerant leakage, lowers the risk of combustion and explosion, and enhances the compressor's energy efficiency and safety.

Abstract
The application provides a protective shell and a compressor, and the protective shell comprises a front cover, a rear shell, the rear shell comprises an inner shell and an outer shell which is detachably sleeved on the inner shell, and an annular area is formed between the inner shell and the outer shell; wherein the front cover can be covered on a sealing end surface of the rear shell and seal the first end opening corresponding to the annular area on the sealing end surface to form a closed isolation cavity. According to the technical scheme of the application, the annular area is formed on the rear shell, and a double-sealing structure is formed in structure, so that the sealing performance is improved. When the inner refrigerant leaks, the isolation cavity formed by the annular area after being sealed by the front cover can play a buffering role, refrigerant is prevented from directly leaking to the outside, the scale of instantaneous refrigerant leakage can be reduced, and the application is suitable for refrigerants with high sealing requirements.
