The micropump underpressure control device comprises a control valve and a transmission tube. The control valve is installed at a supply pipe leading to the micropump and further comprises a case with a membrane, a valve assembly, a connecting rod and a spring. The membrane is exposed to pressure from the outlet of the micropump and accordingly deformed, via the connecting rod controlling opening and closing of the valve assembly, so that working liquid is allowed to proceed to the inlet of the micropump or blocked. The transmission tube transmits pressure at the outlet of the micropump to the membrane. On an opposite side, the membrane is pressed on by working liquid and by the spring. Thus pressure at the inlet of the micropump is controlled, being kept smaller than or equal to pressure at the outlet of the micropump by a fixed difference.
