Technical Field

[0001] The utility model relates to the technical field of compressor controllers, and in particular to a quick-release mechanism for a compressor controller. Background Art

[0002] A compressor is a driven fluid machine that boosts low-pressure gas to high-pressure gas. It is the heart of the refrigeration system. It sucks low-temperature, low-pressure refrigerant gas from the suction pipe, compresses it through the piston driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Compressors usually require a compressor controller to control their operation.
