In the present embodiment, described nut 2 with the concrete link structure of described overcoat 4 is: described nut 2 is provided with shoulder, on the shoulder of described nut 2, be provided with a plurality of through holes, in described overcoat 4, be provided with the extended leg of a plurality of and described through hole adaptation, described extended leg passes described through hole and is inserted in described nut 2, described extended leg is fastened on described appearance cylinder 10, the inner headed face sliding block joint of the periphery of described nut 2 and described overcoat 4.Described valve piston 9 is provided with opening up inner chamber, and described spring 6 is wrapped among the inner chamber of described valve piston 9 and the inner chamber of described large piston 5.Described appearance cylinder 10 sealings are inserted in described bottleneck.Between described appearance cylinder 10 and the end face of described bottle 11, be clamped with pad 7.On described nut 2, fasten and have a button 1.
During use, manufacturer need, by liquid filling in bottle 11, after filling completes, need to be tightened on above-mentioned dropper distributing box on bottleneck.User outwards winding distributing box, get final product solution in sucking-off bottle, and the content being sucked out can be stored in pipette, take out dropper distributing box, the mouth of pipette is placed on palm or desired area, press dispenser push-button or nut, just the liquid in pipette can be discharged, discharge after imbibition liquid in pipe, distributing box is tightened on bottleneck, can prepare next time and use.Distributing box is repeated to implement to outward winding, take out, press and screw operation, just can be by the complete sucking-off of the content in bottle, last content that is connected in bottle bottommost all can sucking-off.
Below in conjunction with accompanying drawing, describe structure and the effect thereof of each parts in detail:
Button 1: these parts are the parts that play decoration function, can use any material manufactures such as plastics, metal, timber, glass, also can cause various profiles.Button is fixed on nut top, when using distributing box, user's distributing box of need to outwarding winding, under the effect of spring, button can upwards rise, and presses button and just can exert pressure to being positioned at the nut of its below, and nut drives large piston to move down, space in compression pipette, reaches the function of discharging content in pipette.The present invention also can not add button, directly presses nut during use.
Nut 2: these parts are mainly manufactured by plastics, is an important functional component, and the top of nut can connect button or not connect button uses.Shoulder at nut has through hole, extended leg in overcoat 4 must insert nut by the through hole of nut shoulder, be fastened with appearance cylinder, the object of through hole is that nut is circumferentially fixed on the coat, can not relatively rotate, make in the axial direction nut sliding block joint on the coat, nut can be slided up and down in overcoat.Inner side at nut is designed with negative thread, and this negative thread will coordinate the outside thread of bottleneck, reach cause screw salable, the separable effect of outwarding winding.The external diameter of nut need coordinate the internal diameter of overcoat, because nut must slide up and down in overcoat, so nut outside dimension will strictly be controlled.
Fixing lock 3: these parts are manufactured by plastics, is assemblied in and holds cylinder top, and by large valve piston, pipette and spring are limited in and hold in cylinder.The necessary fixed function parts of this distributing box.
Overcoat 4: these parts can be used the different manufacture of materials such as plastics, metal, timber.It has two radical functions, and the first, as a decorative element, it is positioned at the most external of distributing box, is the main portion of hand contact, so add different Art Designs and external form, can form different aesthetics.Its other function is: inner headed face is the bearing fit position of nut, and overcoat relies on its inner extended leg to inject nut and holds cylinder and snaps together.When distributing box is outwarded winding and screw, nut slides up and down in overcoat inside, makes amplifying and zooming in and holds the long-pending action of cylinder body.
Large piston 5: these parts are manufactured by plastics, are important functional components, the function of distributing box imbitition realizes by large piston up-and-down movement within holding cylinder.Under large piston, be equipped with spring, when screwing at every turn or pressing button, large piston all can move downward within holding cylinder, thereby reduce to hold cylinder space, realizes the function of discharging air or content.Outward winding nut or unclamp and press button, can make large piston upward movement, thereby increase, holds cylinder capacity, realizes the function that sucks content.Large piston is pressed under nut, and pressing button can move down large piston by nut.Large piston head is designed with through hole, and object is to maintain the inside and outside air pressure balance of large piston.
Spring 6: material can adopt corrosion-resistant steel, its function is just to provide power, presses button or screws nut, and spring pressurized shrinks; Decontrol button or outward winding nut, under the effect of spring restoring force, on large piston, moving and valve piston moves down, thereby increase, holding cylinder space, sucking content.Spring clip is pressed between large piston and valve piston, is to provide the major part of power.
Pad 7: these parts are manufactured by plastics is for sealing the parts of leakproof bottle mouth.
Pipette 8: these parts can be by plastics or glass manufacture, radical function is exactly to store the liquid contents that distributing box is drawn, and is also most important braking function parts.Because, when the present invention will make these parts at the bottom of touching bottle, make imbibition nozzle rest on container bottommost, do not leave, can not excessively contact.Therefore in the time of need to making these parts at the bottom of touching bottle, can return backward a bit of distance, promote the up Compress Spring of valve piston, to discharge descending pressure.
Valve piston 9: these parts are manufactured by plastics, is placed in large piston.These parts provide two functions, and the first, valve piston coated metal spring, makes spring avoid contacting with content.The second, the sense of motion of valve piston is contrary with large piston, and contact pipette, provides distributing box most important function, and that is exactly the action of pipette return.Content at the bottom of why the present invention can draw bottle, because at the bottom of pipette can contact bottle under the not crooked prerequisite not fractureing, therefore pipette will have function that can retrude, when the pipette contact bottle end and after retrude, the return drive disk assembly that must have a pipette, and the power of return passes to spring by valve piston.
Hold cylinder 10: these parts are manufactured by plastics, are major parts of the present invention, all functional components are to be all arranged in advance to hold in cylinder, lock fixing lock, then add upper cap nut and overcoat, and establishment forms.Under appearance cylinder, filling pad, is the important structure parts that form product sealed against leakage.Holding cylinder is also the parts that determine to press discharge rate, and large piston coordinates the volume that holds cylinder, is built into the discharge rate of at every turn pressing, namely the basic function of this dropper.Holding cylinder is also the parts that are interlocked with overcoat, and this holds cylinder overcoat fastening structure, and while making the present invention be tightened on bottleneck, button meeting automatic descending, reaches to discharging in advance air, and when outwarding winding nut, distributing box can suck content automatically.The structure of holding in cylinder sealing insertion bottleneck is another characteristic structure, and this appearance cylinder tie spacer is the design of first sealed against leakage, holds cylinder sealing and inserts bottleneck, and formation second offset-type anti-leak, makes the present invention have stronger leakproof ability.
Bottle 11: stored contents thing.It is attachment of the present invention.
