[0023] Working principle: This electric scroll compressor, when the scroll compressor is working, the low-temperature and low-pressure refrigerant enters the shell 1 through the air inlet groove 14, and the motor 2 drives the scroll compression mechanism to compress the refrigerant, and the compressed refrigerant is discharged through the air outlet groove 15, and the air inlet groove 14 and the air outlet groove 15 are both connected to the annular cover 18, and the pipeline is connected to the annular cover 18 through the joint 20 and the hose 21, so that the air conditioning pipeline is connected to the shell 1 through the annular cover 18, and the annular cover 18 is connected to the shell 1 through the rotation connection formed with the shell 1, which can adjust the air conditioning. The direction of the joint 20 is adjusted, and the joint 20 can be rotated up and down to adjust the up and down direction of the joint 20 through the connection structure that rotates up and down. Through the pipeline connection structure, the connection position of the joint 20 of the scroll compressor can be freely adjusted as needed, thereby facilitating the connection of the scroll compressor with the pipeline in a narrow space. When the motor 2 is working, it can simultaneously drive the rotating shaft 6 at the upper and lower ends to rotate, and the rotating shaft 6 drives the deflection member 8 and the movable scroll 7 to eccentrically rotate through the eccentric shaft 9. At the same time, the refrigerant enters the interior of the shell 1 through the air inlet groove 14. The refrigerant is then passed through the ventilation groove 16 and the air inlet 17 into the space between the movable scroll 7 and the fixed scroll 10. The movable scroll 7 cooperates with the fixed scroll 10 to compress the refrigerant. The compressed refrigerant is discharged from the interior of the housing 1 through the opening 12 and the air outlet groove 15. By setting two sets of fixed scrolls 10 and movable scrolls 7, a single motor 2 can drive two sets of fixed scrolls 10 and movable scrolls 7 to work simultaneously to compress the refrigerant, which can effectively improve the working efficiency of the scroll compressor and effectively reduce the power of the motor 2 at the same working efficiency. To achieve the energy-saving effect and when the joint 20 needs to be rotated up and down, pinch the sliding frames 29 on both sides of the joint 20 at the same time, and then pull the sliding frames 29 to make the sliding frames 29 overcome the elastic force of the springs 31 to drive the second locking teeth 30 to separate from the first locking teeth 25, so that the joint 20 can be rotated up and down through the movable bracket 23 and the rotating rod 24. After the adjustment is completed, release the sliding frame 29, and push the sliding frame 29 toward the first locking teeth 25 through the springs 31, so that the first locking teeth 25 are meshed with the second locking teeth 30, thereby locking the joint 20.
