Abstract
The utility model relates to a kind of hand-held liquid pressing injector, it is formed primarily of liquid container, cylinder barrel, piston, pushing pipe, push switch, spring, playpipe, cylinder barrel is arranged on liquid container, pushing pipe is inserted in the middle of piston, piston to be moved up suction liquid by spring jack-up in cylinder barrel, and piston moves down fluid under pressure by the pressing force of people forces liquid spouting through playpipe from pushing pipe.A kind of hand-held liquid pressing injector hydrojet speed is violent, and not producing spilling during pressing drawing liquid hydrojet, is best life appliance.
Description
Technical field
The present invention relates to a kind of liquid injection apparatus, particularly a kind of push type liquid ejector, belongs to light industry technical field.
Background technology
At some light industry field or agriculture field, as the injection, agricultural spray device etc. of liquid in the extraction of liquid in tank body, tank body, all to use liquid pressing style draw-out device or injection apparatus, these devices take every kind of mode, useful electric pump extracts and sprays, also useful manpower extracts and sprays, and internal junction is formed mostly has piston bore.A lot of pot liquid draw-out devices outwards can overflow a small amount of liquid when repeatedly extracting liquid, not only causes waste, and the liquid overflowed as agricultural atomizer also can threaten Body composition.Why these devices can produce overflowing liquid, be because apparatus structure not science, or piston cylinder device imprecision are compact, or do not arrange the recovery reflux of rational spillage.
Summary of the invention
In order to overcome pumping device not science in general tank body, have spillage or the ineffective shortcoming of hydrojet, a kind of hand-held liquid pressing injector of my invention, this injector only grips control by proficiency, and only can stretch out a thumb and press, just can eject fierce liquid stream or liquid mist.
A kind of hand-held liquid pressing injector taked technical scheme of dealing with problems is: hand-held liquid pressing injector is formed primarily of liquid container, cylinder barrel, piston, pushing pipe, playpipe, push switch, spring, cylinder barrel is arranged in liquid container, piston is had in cylinder barrel, the pushing that interts in the middle of piston is managed, pushing pipe top connects playpipe, push switch is installed in pushing pipe bottom, and piston lower portion mounting spring, also there is push switch the bottom of cylinder barrel.
A kind of hand-held liquid pressing injector mainly relies on the movement of cylinder barrel inner carrier to complete the suction of liquid and pressurization, only has the function that just can reach injection to liquid pressing.Piston by moving up in the liquid suction cylinder barrel in container, then pressurizes the liquid of suction by moving down, and the pushing pipe of the liquid after pressurized in the middle of piston extrudes, then is ejected by playpipe.In active procedure in piston ground cylinder barrel, moving up of piston is that elastic force by spring completes, moving down of piston is that pushing by staff completes, staff is in the process by the downward pushing piston of pushing pipe, the elastic force that not only will overcome spring also will form very large pressure to the liquid of suction, and such liquid just can be forced to eject from pushing pipe.
A kind of hand-held liquid pressing injector can by piston in container in liquid suction cylinder barrel and to form highly pressurised liquid be that the assistance of dependence two push switch realizes because piston moves down: the push switch of piston lower portion is at the end pushing pipe, when piston is upwards pushed up mobile by spring, this switch cuts out, liquid can be drawn in cylinder barrel, when by pushing pipe, pushing is mobile downwards by people for piston, this switch opens, the highly pressurised liquid in cylinder barrel is by the ejection of pushing pipe; Another push switch is in the bottom of cylinder barrel, this switch is contrary with foregoing switching function: when piston moves up, this switch opens, liquid can be drawn into cylinder barrel from this switch, when piston moves down, this switch cuts out, force in cylinder barrel and form highly pressurised liquid, and at this moment, the push switch on piston is but in exhibition state of opening, so liquid flows out from pushing pipe, and spouting by playpipe playpipe.
A kind of beneficial effect of hand-held high-pressure liquid jet device is: a kind of hand-held high-pressure liquid jet device is by installing cylinder barrel motion stops structure in liquid container, and match due to the contrary push switch of two functions and spring, the drawing liquid power that moves up of piston is completed by spring, downward pressing atomizing of liquids is completed by the pressing force of people, and drawing liquid and hydrojet process do not produce discharge, atomizing of liquids is fiercely strong, is best life appliance device.
Accompanying drawing explanation
Fig. 1 is a kind of sectional median plane structure principle chart of hand-held high-pressure liquid jet device.
In figure, 1. playpipe, 2. point handle, 3. liquid container, 4. go up push switch, 5. point handle, 6. cylinder barrel, 7. descend push switch, 8. spring, 9. piston, 10. upper shed.
Detailed description of the invention
Below in conjunction with accompanying drawing, further implementation is done to one hand-held liquid pressing injector.
Fig. 1 shows a kind of sectional median plane structure principle chart of hand-held high-pressure liquid jet device, this is a kind of miniature self-defence liquid-jet device, or a kind of reserve liquid saves operative installations, load liquid excitatory or life liquid in liquid container (3) wherein, the injection that can repeatedly count uses.Cylinder barrel (6) in figure is in liquid container (3), pushing pipe (2) is inserted in the middle of piston (9), pushing pipe (2) top bending part becomes playpipe (1), playpipe (1) level is just in time stained with and is connect a finger handle (5), the lower part outlet of pushing pipe (2) is provided with push switch on (4), push switch (4) moving up and closing product with piston (9) on this, moving down and open with piston (9).Piston lower portion has a spring (8), and the piston (9) that can make puts in place reaches bottom upwards rebounds principle position.In Fig. 1, the bottom of cylinder barrel (6) also has a switch to be lower push switch (7), this lower push switch (7) is opened due to decompression in cylinder barrel (6) when piston (9) person of moving up, piston (9) is transferred the dynamic time downwards and is closed due to cylinder barrel (6) interior supercharging, so liquid is just oppressed spouting through playpipe (1) from pushing pipe (2).
Claims (1)
1. a hand-held liquid pressing injector, it is characterized in that: a kind of hand-held liquid system pressing injector is formed primarily of liquid container, cylinder barrel, piston, pushing pipe, playpipe, push switch, spring, cylinder barrel is arranged in liquid container, piston is had in cylinder barrel, the pushing that interts in the middle of piston is managed, push pipe top connects playpipe, push switch is installed in pushing pipe bottom, and also there is push switch the bottom of piston lower portion mounting spring, cylinder barrel.
