Description

Technical Field

[0001] The invention relates to the technical field of manual pumps, in particular to an air leakage-proof water-leading manual pump. Background Art

[0002] A manual pump is a pump that uses manual force. A one-way manual oil pump is a small hydraulic pump station that converts manual mechanical energy into hydraulic energy. When using a matching oil cylinder and special tools, it can perform various operations, such as lifting, bending, straightening, shearing, riveting, assembling, disassembling, and some construction and military construction.

[0003] The common manual tubular pull-out hand pump relies on the formation of negative pressure to extract air or liquid. The disadvantage is that it cannot automatically continue to discharge the liquid by the siphon effect after the liquid flows out. The reason is that the one-way valve is installed on the middle piston. The valve is basically controlled by a spring to reset or relies on the deformation of elastic rubber material to control the one-way conduction. It cannot conduct by itself without applying external force. The liquid has resistance when passing through and cannot smoothly complete the siphon effect to automatically flow the liquid. Another disadvantage is that when the extracted liquid contains impurities, it is easy to get stuck near the one-way valve, causing negative pressure and positive pressure to leak each other when the pull-out handle piston reciprocates, and the suction efficiency is significantly reduced. The number of pulls and pulls and the speed need to be increased and accelerated to make up for the loss of air leakage. Because the valve is installed on the middle piston, the disassembly and assembly process is complicated and inconvenient to maintain. Some pull-out hand pumps are made of plastic, with low lifespan and impact resistance. There are also oil pumping hand pumps made of steel pipes, but they are prone to rust and the sealing of the inner wall of the pipe is reduced after a long time. Summary of the invention

[0004] 1. Technical issues to be resolved

When the extracted liquid contains impurities, it is easy to get stuck near the one-way valve plate, causing negative pressure and positive pressure to leak from each other when the piston of the pull-out handle moves back and forth.
