And if the actual pressure value is smaller than the preset internal pressure threshold value, generating a flushing increasing signal to increase the liquid inlet flow of the flushing liquid of the flushing module according to the flushing increasing signal so as to increase the internal pressure of the target observation part. If the actual pressure value is equal to the preset internal pressure threshold value, generating a flushing maintenance signal, and maintaining the liquid inlet flow of the flushing liquid of the flushing module according to the flushing maintenance signal so as to maintain the internal pressure of the target observation part.
