Claim 8:
9. The electrical control system for minimally invasive tumor therapies according to claim 8, wherein the control module is further configured to:
determine whether the vacuum tank pressure intensity is less than a seventh pressure intensity threshold value for a third preset duration;
control, if the vacuum tank pressure intensity is not less than the seventh pressure intensity threshold value for the third preset duration, the air compressor and the vacuum pumping valve to open, and return to perform an operation step of determining whether the vacuum tank pressure intensity is less than a seventh pressure intensity threshold value for a third preset duration, wherein the third preset duration is 1 minute and the seventh pressure intensity threshold value is 10 KPa; and
control, if the vacuum tank pressure intensity is less than the seventh pressure intensity threshold value for the third preset duration, the air compressor and the vacuum pumping valve to close, and perform the operation step of controlling the vacuum tank liquid charging valve to open.
