During use, manufacturer need, by liquid filling in bottle 11, after filling completes, need above-mentioned dropper distributing box to be tightened on bottleneck.Distributing box is outwarded winding by user, get final product solution in sucking-off bottle, and the content be sucked out can be stored in pipette, take out dropper distributing box, the mouth of pipette is placed on palm or desired area, pressing dispenser push-button or nut, just the liquid in pipette can be discharged, after discharging imbibition liquid in pipe, distributing box is tightened on bottleneck, can prepares to use next time.Repeat enforcement to distributing box to outward winding, take out, press and screwing operations, just can the complete sucking-off by the content in bottle, last content being connected in bottle bottommost all can sucking-off.
Structure and the effect thereof of each parts is described in detail below in conjunction with accompanying drawing:
Button 1: these parts are the parts playing decoration function, can use any material manufactures such as plastics, metal, timber, glass, also can cause various profile.Button is fixed on nut top, when using the dispenser, user needs distributing box of outwarding winding, under the action of the spring, button can upwards rise, and pressing button just can apply pressure to the nut be positioned at below it, 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, primarily of plastics manufacture, are important functional components, the top of nut can connect button or not connect button and uses.Through hole is had at the shoulder of nut, 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 makes nut circumference fixing on the coat, can not relatively rotate, make nut sliding block joint in the axial direction on the coat, nut is slided up and down in overcoat.Be designed with negative thread in the inner side of nut, this negative thread will coordinate the outside thread of bottleneck, reach cause screw salable, 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 control.
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: the manufacture of materials that these parts can use plastics, metal, timber etc. different.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 forms different aesthetics.Its other function is: inner headed face is the bearing fit position of nut, and overcoat relies on the extended leg of its inside to inject nut and holds cylinder and snaps together.When distributing box is outwarded winding and screw, nut slides up and down at jacket internal, makes amplifying and zooming in and holds the long-pending action of cylinder body.
Large piston 5: these parts are manufactured by plastics is an important functional component, and the function of distributing box imbitition is realized by large piston up-and-down movement in appearance cylinder.Be equipped with spring under large piston, when screwing at every turn or press button, large piston all can move downward in appearance cylinder, thus reduces to hold the function that cylinder space realizes discharging air or content.To outward winding nut or unclamp pressing button, then can make large piston upwards, thus increase and hold cylinder capacity, realize the function sucking content.Large piston is pressed under nut, and pressing button can make large piston move down by nut.Large piston head is designed with through hole, and object maintains the air pressure balance inside and outside large piston.
Spring 6: material can adopt corrosion-resistant steel, its function is just to provide power, pressing button or tightening nuts, and spring pressurized shrinks; Decontrol button or outward winding nut, under the effect of spring-return power, large piston moving and valve piston moves down, thus increasing appearance 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 the parts for sealing leakproof bottle mouth.
Pipette 8: these parts can by plastics or glass manufacture, and radical function is exactly the liquid contents that storage 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.A bit of distance can be return backward when therefore needing to make these parts at the bottom of touching bottle, promote the up Compress Spring of valve piston, to discharge downstream 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, and provide the most important function of distributing box, 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 bending prerequisite do not fractureed, therefore will have can the function of retrude for pipette, at the bottom of pipette contact bottle after retrude, must have the return drive disk assembly of 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 all be arranged in advance to hold in cylinder, and lock fixing lock, then add upper cap nut and overcoat, establishment is formed.Under appearance cylinder, fill pad, be the important feature parts forming product sealing and anti-leakage.Holding cylinder is also the parts determining pressing discharge rate, and large piston coordinates the volume holding cylinder, is built into the discharge rate of each pressing, the namely basic function of this dropper.Holding cylinder is also the parts be interlocked with overcoat, and this holds cylinder overcoat fastening structure, and when making the present invention be tightened on bottleneck, button meeting automatic descending, reach to discharging air in advance, and when outwarding winding nut, distributing box can suck content automatically.The structure held in cylinder sealing insertion bottleneck is another characteristic structure, and this appearance cylinder tie spacer is the design of first sealing and anti-leakage, holds cylinder sealing and inserts bottleneck, and formation second offset-type anti-leak, makes the present invention have stronger leakage prevention.
Bottle 11: stored contents thing.It is attachment of the present invention.
