摘要： A hand-depressing vacuum pumping device includes a liquid container having a top connected to a guide cover, which has a first passage in communication with an interior receiving space of the liquid container, a float-based safety switch, a check valve, and an exposed tube connected to a top of a pump cylinder. The pump cylinder includes a one-way piston arranged therein and the one-way piston is connected to a piston rod and a pressing stem. The pump cylinder has a bottom end connected to a second passage of the guide cover. Depressing the pressing stem downward causes the one-way piston to expel air out and pulling the pressing stem upward causes air to flow from the interior of the liquid container through the one-way piston to the bottom of the pump cylinder so as to evacuate the receiving space of the container to generate vacuum that induces a suction force.
