Embodiment

Below the preferred example of hydraulic-pneumatic manual pump according to the invention, therefore do not limit protection scope of the present invention.

With reference to Fig. 1; A kind of hydraulic-pneumatic manual pump is provided, comprises hollow base 1, the import 2 that is connected with hollow base 1 internal cavities; Also comprise the pump housing pipe 3 that is fixedly connected with the upper opening of said hollow base 1; Be arranged with storage pressure pipe 4 in the pump housing pipe 3, the upper end of pump housing pipe 3 is provided with sealing cover 5, and storage presses pipe 4 lower ends to be installed with one can be along the piston apparatus 6 of pump housing pipe 3 inwalls slip; Storage is pressed the upper end of pipe 4 from sealing cover 5, to stretch out with handle 7 and is fixedly connected; Storage presses pipe 4 also to be provided with and to store up the outlet connection 8 of pressing pipe 4 to be connected with the joint of handle 7, is equiped with a float valve 9, formation one vacuum chamber 10 between piston apparatus 6 and the float valve 9 in said hollow base 1 internal cavities and the passage that import 2 is connected.

Said piston apparatus 6 is to be made up of the seal ring 13 that the piston seat nut 12 of pressing coupling nut 11 that pipe 4 lower ends are fixedly connected with storage, be fixedly connected with coupling nut 11 lower ends is set between coupling nut 11 and the piston seat nut 12; Piston seat nut 12 bottoms have the through hole that is connected with vacuum chamber 10, are equiped with the floating type piston ball 14 that adapts with this through hole in the piston seat nut 12, and storage pressure pipe 4 lower ends are provided with and are used for floating type piston ball 14 is carried out spacing position-limited lever 15; Being shaped as of said seal ring 13 is big up and down; Middle thin, seal ring 13 is an interference fit with the inwall of pump housing pipe 3, and sealing circle 13 is the silica gel member; In moving up and down, seal with pump housing pipe 3 inwalls; In addition, when vacuum chamber 10 pressure are excessive, can upwards dig pressure release, to protect outlet end not booster and the sealing that damages other interfaces; Liquid can press the gap between pipe 4 outer walls to discharge from coupling nut 11 and storage, and said hollow base 1 internal cavities top is provided with and is used for pressing pipe 4 to carry out spacing position-limited lever 16 to storage.

Also be installed with a foot-operated ring 27 on the sidewall of said hollow base 1.

During reset condition, because the sealing process of seal ring 13 and float valve 9, make the seal ring 13 in the pump housing pipe 3 be in vacuum state with the bottom; Become vacuum chamber 10, when being pulled upwardly handle 7, when float valve 9 is raised; Air or liquid in the import 2 are inhaled into; Along with handle 7 constantly raises, air or liquid are filled in the continuous vacuum chamber 10 that increases in space, have accomplished the set-up procedure of work.

When handle 7 when pressing down, float valve 9 is pressed downward, and is close to the aperture and blocks backflow; The pressure that forms in the vacuum chamber 10 is the floating type piston ball 14 of jack-up up, and fluid upwards presses pipe 4 to discharge through storage, and speed that handle 7 presses down and pressure are big more; Storage presses the pressure of deposit in the pipe 4 big more; When handle 7 is depressed into bottom of travel, the fluid in the vacuum chamber 10 is all replaced storage with pressure and is pressed in the pipe 4, when the pressure of managing in 4 is pressed in storage more than or equal to the pressure of vacuum chamber 10; Floating type piston ball 14 has clogged the through hole of piston seat nut 12 again under deadweight or pipe internal pressure, accomplish a work cycle.

When the speed that moves up and down at handle 7 is enough fast,, still there is fluid to discharge, reaches the effect of continuous discharge even in the uphill process of handle 7.

With reference to Fig. 2, when this pump used as sprayer, outlet connection 8 was connected with spraying device 17, and this spraying device 17 is the connecting tubes 18 that are connected by with outlet connection 8, and the shower nozzle 19 that is connected with connecting tube 18 constitutes, and promptly can be used as sprayer and uses.

With reference to Fig. 3; When this pump uses as air pump; Outlet connection 8 is connected with inflator 20, and this inflator 20 is the connecting tubes 18 that are connected by with outlet connection 8, and the charging air inlet 21 that is connected with connecting tube 18 constitutes; Can inflate to the equipment of needs such as balloon, bicycle, motorcycle, rubber dinghy inflation, use as inflatable tool.

With reference to Fig. 4, when this pump used as liquid pump, outlet connection 8 was connected with effluent control device 22; Effluent control device 22 is connected with outlet connection 8 through connecting tube 18, and this effluent control device 22 is the water taps 23 that are connected by with outlet connection 8, and the water purifier 24 that is connected with water tap 23 constitutes; When water tap 23 was opened, water directly directly flowed out from the outlet 25 of water tap 23, when water tap 23 is closed; Water flows in the water purifier 24; Flow out from the outlet 26 of water purifier 24, can the water that take out be purified, become and purify waste water.Can be used as the temporary pressure source of the instrument and the filter of the transmission of various use low pressure.
