Abstract
The utility model discloses a handheld electric vacuum pump. The handheld electric vacuum pump comprises an upper housing and a lower housing which are fastened in a matched way, wherein an air pump, a button switch and a control circuit board are arranged in a cavity body formed by the upper housing and the lower housing; a pressure switch is arranged on the control circuit board; an air inlet of the air pump is connected with an air suction nozzle supporting head through a soft pipe A and communicated with an air suction nozzle; and an air outlet of the air pump is connected with the pressure switch on the control circuit board through a soft pipe B. As the air outlet of the air pump is connected with the pressure switch through the soft pipe B, the pressure of the air outlet of the air pump is gradually reduced in the vacuum pumping process of the vacuum pump, and the control circuit board controls the air pump to stop working when the pressure switch detects that the pressure is reduced to a setting value. Therefore, the pressures in vacuum refreshing tanks can keep constant to satisfactorily guarantee the food refreshing effect.
