Abstract
A hand-operated vacuum pumping device comprises a seal ring, a check valve element A, a check valve element B, elastic devices, a switch connecting piece, a guide block, a valve element guide block, a gas inlet piece, a fixing device, a gasket, a nylon piece, a piston, a piston rod, an air cylinder body, a gas outlet piece, a pin and a handle. According to the hand-operated vacuum pumping device, when the piston is driven by the handle to be pulled out, the gas pressure in a left cavity of the device is lower than the gas pressure outside the left cavity, the check valve element B is locked under the action of a spring so that the check valve element A can move rightward after overcoming the resistance of the spring, and gas suction is achieved. When the handle drives the piston to be pushed forward, the inner gas pressure is larger than the outer gas pressure, at the moment, the check valve element A is locked under the action of the spring so that the check valve element B can move upward after overcoming the resistance of the spring, and gas can be discharged.
