Bottle neck in every profession and trade and each sphere of life using relatively wide, in order to seek a kind of practical, with low cost and flow velocity,
The controllable bottle neck of flow, present inventor has performed substantial amounts of research work, inventor has found to pass through by contrast experiment repeatedly
Air inlet pipe is set inside air inlet, by controlling the air admission hole of air inlet pipe and the ratio of liquid outlet internal diameter, it is ensured that flow velocity
The control of stable and flow.Typically in order to control air inlet air inlet without going out liquid, can usually be installed in air inlet one it is similar
The part of non-return valve operational principle, and the air inlet for being not provided with check valve this part is typically designed and is being provided with the bottle of suction pipe
Mouthful, for not possessing the common bottle neck of pumping function, by design air inlet pipe control liquid outlet flow speed stability, flow control be in
Professional institute is unimaginable.The present inventor has made intensive studies to air inlet pipe, completes the present invention.
Found in groping：
Liquid outlet and air inlet are only opened up on partition, during pouring liquid, two mouths have liquid flow
Go out, now howsoever the internal diameter of regulation liquid outlet and air inlet is unable to reach preferable effect, sent out in substantial amounts of experiment
Now go out after air inlet pipe liquid effect and improve when being installed in air inlet, liquid can be used and reached balance with air inlet, only this
In the case of go out liquid and can be just completely separated with air inlet, liquid outlet is liquid and be not involved in air inlet；Air inlet is air inlet without going out
Liquid, so that the structure for reaching and replacing air inlet lower end to set one-way valve member.This structure goes out liquid could be smooth, and flow velocity is very
Uniform is not in the generation of expulsion events, and flow can be controlled arbitrarily, and a continuous parabola could be turned into by going out liquid track.
In the present invention the internal diameter of liquid outlet be more than air admission hole internal diameter, air admission hole internal diameter be preferably but not limited to 1.5 to 10.6mm it
Between, liquid outlet internal diameter is preferably but not limited to 8 between 45mm, when the viscosity of liquid is different, adjustment air inlet bore
Size is that achievable flow velocity is controllable.
Inventor also found in in-depth study repeatedly, set filter to can be very good to reach this in the inside of air inlet pipe
The purpose for the control liquid outlet flow rate that invention is wanted.The inside diameter ranges of air inlet pipe are appropriate, if the small meeting of air inlet bore
Air inflow is directly influenced, liquid is gone out in pouring liquid and does not reach balance with air inlet, going out liquid and air inlet can not be completely separated, and go out liquid
The phenomenon having some setbacks just is had, liquid outlet had not only gone out liquid but also air inlet, cause out liquid intermittently, flow velocity, flow are uncontrollable.Air inlet
The internal diameter of pipe is transferred to suitable value, goes out liquid and is kept completely separate with air inlet, and it is smooth to go out liquid, and flow velocity is uniform, goes out liquid track as a company
Continuous parabola；Inventor has found, when air admission hole internal diameter takes bigger numerical, among the process of frequent pouring liquid,
Although liquid outlet stability of flow can be controlled, do not notice that liquid will be rushed out from the air inlet in air inlet pipe slightly, cause
Air inlet goes out liquid phenomenon, directly influences out the stationarity of liquid track.Therefore, for heavy caliber air inlet pipe, inventor has found
The inside of air inlet pipe or one layer of tip designs or two layers of filter（According to different liquids and different containers, filter is in air inlet pipe
Position and the number of plies it is also different）, so a heavy caliber air inlet pipe can be divided into multiple small-bore air inlet pipe, purpose is just
It is increase fluid on-way resistance, liquid would not be gone out from air inlet among with the process of the frequent pouring liquid of any angle
Come.At this moment, liquid outlet is bigger than the liquid pressure of air inlet position, and liquid outlet goes out liquid at once, with the outflow of liquid, receptacle
Liquid pressure be gradually reduced, the liquid pressure of air inlet bottom of the tube is also reducing, and does not have extra liquid to help behind air admission hole
Thrust, in the case where liquid pressure is gradually reduced, liquid, which will not flow out, to be come, also, with the increasing of air admission hole, will be entered
Tracheae is further added by certain length, and such fluid on-way resistance will be increased, and especially for the high liquid of viscosity, be hindered along journey
Power can be bigger, while the liquid pressure also increased between liquid outlet and air admission hole is poor, enters to air from air admission hole and provides
Many-sided favourable condition.
The design principle of the present invention is based on considered below：
When liquid flows, the presence due to the cohesive force of fluid molecule and with solid wall surface adhesive force makes in liquid
Speed everywhere produces difference, and the speed that liquid flows in pipeline is simultaneously unequal, and the liquid velocity for being close to tube wall is zero, pipeline
The speed of center is maximum, i.e. here it is the frictional force on-way resistance that liquid is produced when being flowed in pipeline.When liquid exists
When being flowed in pipe with certain speed, pipeline is longer, and caliber is smaller, and on-way resistance is bigger, and the size of on-way resistance additionally depends on pipe
The pressure that the roughness of wall is born with the speed and liquid of flowing.Under field conditions (factors), liquid wants the air inlet from air inlet pipe
Flowed out at hole and just necessarily be formed a drop, and the convex surface for forming a drops causes to add surface area needs consumption volume
Outer power could be completed, because liquid and air inlet pipe periphery have behind the presence of internal friction between absorption affinity and liquid, drop
A boosting power is needed, the cambered surface for allowing drop to overcome these resistances to form water droplet can just fall down.Process of the liquid in flowing
In the on-way resistance that is produced to tube wall and the internal diameter of tube wall be inversely proportional, bore is thinner, and resistance is bigger.And air is in low speeds flow
In to the frictional force very little of tube wall, for filter due to the effect of atmospheric pressure do not influence air by property, people are as the saying goes：Pin
The big hole of point can be exactly this reason through the big wind that struggles against.Therefore, increase filter be in increase container air inlet position liquid along journey
The effective ways of resistance, especially for the big liquid of viscosity, on-way resistance can be bigger, while not influenceing air inlet effect again.
The surf the Net big I of intraocular footpath and filter thickness of filter is adjusted according to actual needs, the size of mesh with along journey
Resistance is inversely proportional, and the thickness of filter is directly proportional to on-way resistance, i.e.,：The smaller on-way resistance of mesh is bigger；The thickness of filter is bigger,
On-way resistance is bigger.So, the need for the size of various inlet bore and different liquids viscosity, choose different meshes
Size is matched with certain filter thickness, still, and this matching is not unique, that is to say, that：When mesh is chosen slightly
When big, it can be made up by increasing the thickness of filter, vice versa.It is attained by the need for can meeting air inlet, again
It can guarantee that the final purpose that liquid will not be flowed out in air inlet.The preferred mesh for being not limited to filter in the present invention
Aperture is 0.1-2.0mm, and the thickness of filter is 0.1-10mm.Those skilled in the art can the design based on the present invention, process
Experiment obtains that the suitable filter mesh pore diameter range of purpose and filter thickness range that an air inlet does not go out liquid can be met, and these all should
When cover the present invention scope within.
The longer the better on the length ideal of air inlet pipe in the present invention, but air inlet pipe is oversize to have many drawbacks：First,
Air inlet pipe more long production cost is higher, and the mould of production bottle neck will change with streamline, and the assembly cost of bottle neck will increase, filling
The production line of liquid will also change, and this series of change can all increase many costs, be unfavorable for industry energy conservation consumption reduction.Second,
Immersion in a liquid, for liquid food, easily causes query of the consumer to product quality to air inlet pipe for a long time.
Third, for easily producing the liquid of crystallization, the bottom of air inlet pipe is easily blocked.It is believed that people in the art
Member can be in the concept that illustrates of the present invention to air inlet pipe length, internal diameter select, to reach flow quantity, flow velocity
The stably and controllable purpose with uniformity coefficient, can meet out being completely separated for liquid and air inlet so that go out that liquid is very smooth, flow velocity is equal
Even, flow is controllable, goes out liquid track into a continuous parabola, is not in expulsion events, the steady air inlet of air inlet, without liquid
Body flows out from air inlet, more be not in two mouths while going out liquid or not only going out liquid but also the mixed effect of air inlet, simultaneously so that bottle neck
Cost reduce many.
Compared with prior art, what the present invention was obtained has the beneficial effect that：
Practical bottle neck provided by the present invention is provided with air inlet and liquid outlet, and air inlet is connected with air inlet pipe, air admission hole
Internal diameter be less than liquid outlet internal diameter, during pouring liquid, air admission hole be located at liquid outlet upper end, it is small in the fluid pressure of air inlet position
Fluid pressure at liquid outlet, when pouring liquid, liquid selective from liquid outlet outflow.When the liquid outflow in bottle
After a part, air pressure inside step-down, the pressure of now air inlet extraneous air formation is more than bottle internal liquid and produced in air inlet position
Raw pressure, gas enters from air inlet, maintains bottle inner and outer air pressure stable, so go out liquid and air inlet with very high frequency replace into
Go, reach the purpose of control liquid outlet flow speed stability.The bottle nozzle structure that the present invention is provided is simple, flow velocity, flow easy-control, cost
It is cheap.
In order to reach more preferable effect, filter is added inside air inlet pipe, due to the presence of filter, filter self-assembling formation number
Individual aperture, further ensures and liquid is blockaded, and reaches that air admission hole air inlet does not go out liquid, liquid outlet only goes out the effect of liquid not air inlet
Really.
For the difference according to liquid, and be convenient for changing air inlet pipe, it is preferred that air inlet pipe bottom can be set on partition
Seat, with the difference of liquid, the air inlet pipe of required internal diameter and length is installed on the air inlet pipe base.Such as：
1st, it is 2.5 liters of container for capacity, it is edible oil to contain thing, liquid outlet internal diameter D is 8.5 mm, air admission hole internal diameter
F is that filter is not provided with inside 1.8mm, air inlet pipe, and now intake manifold length L is 35 mm；
2nd, same, capacity is 2.5 liters of container, and it is soy sauce to contain thing, and liquid outlet internal diameter D is 8.5 mm, air admission hole internal diameter F
For 1.6mm, filter is not provided with inside air inlet pipe, now intake manifold length L is 34 mm；As long as changing air inlet pipe, other bottle necks
Main body is constant, and soy cruet can liquid and reached preferable effect with air inlet, because air inlet pipe is very small, change to use
When saves time and effort saved many production costs.
3rd, for the container that capacity is 230ml, it is sesame oil to contain thing, and liquid outlet internal diameter D is 8.0 mm, air admission hole internal diameter
F is that filter is not provided with inside 1.4mm, air inlet pipe, and intake manifold length L is 33 mm；
4th, same, capacity is 230ml container, and it is vinegar to contain thing, and liquid outlet internal diameter D is in 8.0 mm, air admission hole

Mouth main body is constant, and vinegar bottle can liquid and reached preferable effect with air inlet, equally also save and be much produced into use
This.It was only to list several edible liquids just now, non-edible liquid is such as because the species of liquid is various：Gasoline, diesel oil, vapour
Car machine oil, lubricating fluid, chemical liquid etc., if each opens a secondary mould come if producing bottle neck, the quantity of mould is very
Greatly, huge production cost is brought to manufacturing enterprise, great waste is caused.
In order that air inlet pipe and air inlet pipe base stable connection, it is to avoid air inlet pipe comes off in use, air inlet pipe of the invention
Outer wall is provided with air inlet Pipe Flange, and is provided with air inlet pipe neck in air inlet pipe base, make use of elasticity of plastics to deform big
Principle, when air inlet pipe is inserted into air inlet pipe base, the flange in air inlet pipe is fallen into the neck inside air inlet pipe base, air inlet
Pipe again can not be separated voluntarily, only could be taken out air inlet pipe in the case of by instrument and powerful external force, thus be kept away
Exempt from after bottle neck is installed on bottle, air inlet pipe oneself, which comes off, among the process that product is transported for long-distance or used drops to container
The central possibility as foreign matter.
Be both provided with seal at air inlet of the present invention and liquid outlet, it is ensured that be packaged with the bottle of liquid in transport or
The sealing of preceding bottle neck is used so that liquid will not flow out from two opennings, during first pouring liquid, while removing two sealings
Part.

The present invention when in use, when first pouring liquid, removes the seal of liquid outlet first, then by air inlet
Sealing nail removes, and liquid outlet and air inlet is all opened, with any angle pouring liquid, because the internal diameter of air admission hole is less than liquid
Liquid in the internal diameter of mouth, bottle flows out from liquid outlet, and after liquid pours out a part from liquid outlet, the air pressure in bottle diminishes,
The pressure that outside air is produced at air inlet is more than the pressure of liquid in bottle to air inlet position surface, and now gas is from air inlet
Mouth is entered in bottle by air admission hole, until inside and outside air pressure balance.During pouring liquid, due to the position of air admission hole it is high and
The position of liquid outlet is low, therefore, and the liquid pressure at air inlet is less than the liquid pressure at liquid outlet, and air is preferentially from air inlet
Into bottle, being completely separated for liquid and air inlet is realized out, going out liquid will be steady, it is to avoid liquid outlet enters liquid caused by air
The phenomenon of the even splash of flow velocity, mass flow discrepancy, it is ensured that liquid outlet flow velocity is smooth, flow is controllable.
