摘要： A handheld vacuum suction device includes: an exterior case; a cap that includes a suction nozzle; a pressure switch unit that includes a pressure switch having a slide body configured to descend against a spring when a pressure in the cap falls below a predetermined pressure, to thereby cut off power supply, and a vertical through suction duct; a vacuum pump that includes an inlet port connected to the suction duct and sucks in air; and a control that includes an actuating switch, and is electrically connected to the vacuum pump and the pressure switch to control the actuation of the vacuum pump.
