At this time, the machine needs to be pressurized to keep the pressure inside the machine stable so that the machine can work normally.

[0003] In the related art, a compressor is usually used to continuously pump a corresponding pressure-compensating medium into the interior of the device to compensate for the pressure of the machine, thereby maintaining a certain stability of the pressure inside the machine so that the machine can be used normally.
