Bottle neck is applied wider in every profession and trade and each sphere of life, in order to seek the controlled bottle neck of a kind of practicality, with low cost and flow velocity, flow, present inventor has performed a large amount of research, contriver finds by arranging air inlet pipe in admission port inside through contrast experiment repeatedly, by controlling the induction opening of air inlet pipe and the ratio of liquid outlet internal diameter, flow speed stability and flow control can be ensured.Generally in order to control an admission port air inlet and non-fluid; the parts of a similar non-return valve operational principle usually can be installed in admission port; and the admission port not arranging these parts of check valve generally designs and is being provided with the bottleneck of suction pipe; for the common bottle neck not possessing pumping function, be unimaginable in insider institute by design air inlet pipe control liquid outlet flow speed stability, flow control.The present inventor conducts in-depth research air inlet pipe, completes the present invention.
Find in groping:
Only on partition, offer liquid outlet and admission port, in the process of pouring liquid, two mouths all have liquid and flow out, now regulate the internal diameter of liquid outlet and admission port all cannot reach desirable effect howsoever, in a large amount of experiments, find that fluid effect improves after installing air inlet pipe in admission port, fluid and air inlet can be made to reach balance, and only have fluid in this case could thoroughly be separated with air inlet, liquid outlet is fluid and does not participate in air inlet; Admission port is air inlet and non-fluid, thus reaches and replace the structure that admission port lower end arranges one-way valve member.This structure fluid could be smooth and easy, and flow velocity very evenly there will not be the generation of expulsion events, and flow can arbitrarily control, and fluid track just can become a continuous print parabola.The internal diameter of liquid outlet is greater than the internal diameter of induction opening in the present invention, induction opening internal diameter is preferably but not limited between 1.5 to 10.6mm, liquid outlet internal diameter is preferably but not limited between 8 to 45mm, and when the viscosity of liquid is different, it is controlled that the size of adjustment air inlet pipe internal diameter can realize flow velocity.
Contriver also finds in repeatedly deep research, arranges the object that filter can well reach the control liquid outlet flow rate that the present invention wants in the inside of air inlet pipe.The inside diameter ranges of air inlet pipe is wanted suitably, if the little meeting of air inlet pipe internal diameter directly has influence on suction quantity, when pouring liquid, fluid and air inlet out of reach balance, fluid cannot thoroughly be separated with air inlet, fluid just has the phenomenon had some setbacks, liquid outlet not only fluid but also air inlet, cause fluid intermittent, flow velocity, flow are uncontrollable.The internal diameter of air inlet pipe is transferred to suitable value, and fluid is separated completely with air inlet, and fluid is smooth and easy, and flow velocity is even, and fluid track becomes a continuous print parabola; Contriver finds, when induction opening internal diameter gets bigger numerical time, in the middle of the process of frequent pouring liquid, although liquid outlet stability of flow can be controlled, but slightly do not notice that liquid will be rushed out from the admission port air inlet pipe, cause admission port fluid phenomenon, directly have influence on the stationarity of fluid track.Therefore, for heavy caliber air inlet pipe, contriver finds at the inside of air inlet pipe or tip designs one deck or two-layer filter (according to different liquids and different containers, the position of filter in air inlet pipe is also different with the number of plies), a heavy caliber air inlet pipe can be divided into multiple small-bore air inlet pipe like this, object increases fluid on-way resistance exactly, would not rush out with liquid in the middle of the process of arbitrarily angled frequent pouring liquid from admission port.At this moment, liquid outlet is larger than the liquid pressure of air inlet position, liquid outlet is fluid at once, along with the outflow of liquid, the liquid pressure of receptacle is reducing gradually, liquid pressure bottom air inlet pipe is also in reduction, extra liquid boosting power is not had after induction opening, when liquid pressure reduces gradually, liquid can not flow out, and, along with the increasing of induction opening, air inlet pipe is increased certain length again, such fluid on-way resistance will strengthen, particularly for the liquid that viscosity is high, on-way resistance can be larger, the liquid pressure simultaneously also increased between liquid outlet and induction opening is poor, to enter from induction opening to air and provide many-sided favourable condition.
Principle of design of the present invention is based on following consideration:
When flow of liquid, due to the binding force of fluid molecule and the existence with solid wall surface adhesive ability, make speed generation difference everywhere in liquid, the speed that liquid flows in pipeline is also unequal, the liquid velocity being close to tube wall is zero, the speed of pipeline center is maximum, the friction force that Here it is produces when liquid flows in pipeline i.e. on-way resistance.When liquid flows with certain speed in managing, pipeline is longer, and caliber is less, and on-way resistance is larger, and the size of on-way resistance also depends on the pressure that the roughness of tube wall and the speed of flowing and liquid bear.Under field conditions (factors), liquid wants to flow out from the air inlet position of air inlet pipe just to form a drop, and form a drop-shaped convex surface and cause adding face area and need to consume extra power and just can complete, because liquid and air inlet pipe periphery have the existence of internal friction between adsorption affinity and liquid, need a boosting power after drop, the cambered surface allowing drop overcome these resistances formation water droplet just can fall down.Liquid is inversely proportional to the on-way resistance of tube wall generation and the internal diameter of tube wall in the process of flowing, and the thinner resistance of bore is larger.And air is very little to the friction force of tube wall in low speeds flow, for filter because atmospheric effect does not affect the crossing ability of air, people as the saying goes: the hole that needle point is large can be exactly this reason through the large wind of bucket.Therefore, increasing filter is the effective ways increasing air inlet position liquid on-way resistance in container, and particularly for the liquid that viscosity is large, on-way resistance can be larger, do not affect air inlet effect again simultaneously.
The large I of filter online intraocular footpath and filter thickness adjusts according to actual needs, and size and the on-way resistance of mesh are inversely proportional to, and the thickness of filter is directly proportional to on-way resistance, that is: the less on-way resistance of mesh is larger; The thickness of filter is larger, and on-way resistance is larger.So, according to the size of various inlet bore and the needs of different liquids viscosity, choose different width of meshs to mate with certain filter thickness, but, this coupling is not unique, that is: when mesh choose slightly large time, can make up by strengthening the thickness of filter, vice versa.The needs that can meet air inlet can be reached, the final purpose that liquid can not flow out from admission port can be ensured again.The aperture being preferably not limited to the mesh of filter in the present invention is 0.1-2.0mm, and the thickness of filter is 0.1-10mm.Those skilled in the art can based on design of the present invention, and obtain meeting the suitable filter mesh pore diameter range of the object of an air inlet not fluid and filter thickness range through experiment, these all should be encompassed within scope of the present invention.
In the present invention air inlet pipe length ideal on the longer the better, but air inlet pipe is oversize can exist a lot of drawback: one, more long production cost is higher for air inlet pipe, mould and the conveyor line of producing bottle neck will change, the assembly cost of bottle neck will increase, the manufacturing line of filling liquid also will change, and this series of change all can increase many costs, is unfavorable for that industry energy conservation lowers consumption.Its two, air inlet pipe soaks in a liquid for a long time, especially for liquid food, easily causes customer to the query of product design.Its three, for easily producing the liquid of crystallization, the easy shutoff in bottom of air inlet pipe.The present inventor believes the length to air inlet pipe in the concept that those skilled in the art can set forth in the present invention, internal diameter is selected, to reach flow quantity, flow velocity and degree of uniformity stablize controlled object, thoroughly being separated of fluid and air inlet can be met, make fluid very smooth and easy, flow velocity is even, flow is controlled, fluid track becomes a continuous print parabola, there will not be expulsion events, the steady air inlet of admission port, liquid is not had to flow out from admission port, more there will not be two mouths fluid or not only fluid but also the mixed effect of air inlet simultaneously, simultaneously, the cost of bottle neck is reduced many.
Compared with prior art, the beneficial effect that obtains of the present invention is as follows:
Practical bottle neck provided by the present invention is provided with admission port and liquid outlet, admission port is connected with air inlet pipe, the internal diameter of induction opening is less than the internal diameter of liquid outlet, during pouring liquid, induction opening is positioned at liquid outlet upper end, the fluid pressure at liquid outlet place is less than at the fluid pressure of air inlet position, when pouring liquid, flowing out from liquid outlet of liquid selective.After the liquid in bottle flows out a part, air pressure inside step-down, the pressure that now admission port extraneous air is formed is greater than the pressure that bottle internal liquid produces at air inlet position, gas enters from admission port, maintain bottle inner and outer air pressure to stablize, fluid like this and air inlet hocket with very high frequency, reach the object controlling liquid outlet flow speed stability.Bottle nozzle structure provided by the invention is simple, and flow velocity, flow easy-control are with low cost.
In order to reach better effect, add filter in air inlet pipe inside, due to the existence of filter, the several aperture of filter self-assembling formation, further ensures blockading to liquid, reaches an induction opening air inlet not fluid, the effect of a liquid outlet fluid not air inlet.
In order to the difference according to liquid, and be convenient for changing air inlet pipe, preferably, can air inlet pipe base be set on partition, along with the difference of liquid, the air inlet pipe of required internal diameter and length is installed on described air inlet pipe base.Such as:
1, for capacity be the container of 2.5 liters, splendid attire thing is cooking oil, and liquid outlet internal diameter D is 8.5 mm, and induction opening internal diameter F is 1.8mm, and air inlet pipe inside does not arrange filter, and now intake manifold length L is 35 mm;
2, same, capacity is the container of 2.5 liters, and splendid attire thing is soy sauce, and liquid outlet internal diameter D is 8.5 mm, and induction opening internal diameter F is 1.6mm, and air inlet pipe inside does not arrange filter, and now intake manifold length L is 34 mm; As long as replacing air inlet pipe, other bottle neck main body is constant, and soy cruet just can employ, and fluid and air inlet reach desirable effect, because air inlet pipe is very little, had not only saved time but also laborsavingly saved a lot of productive costs during replacing.
3, be the container of 230ml for capacity, splendid attire thing is sesame seed oil, and liquid outlet internal diameter D is 8.0 mm, and induction opening internal diameter F is 1.4mm, and air inlet pipe inside does not arrange filter, and intake manifold length L is 33 mm;
4, same, capacity is the container of 230ml, and splendid attire thing is vinegar, and liquid outlet internal diameter D is 8.0 mm, and induction opening internal diameter F is 1.5mm, and air inlet pipe inside does not arrange filter, and intake manifold length L is 30 mm; Also be only change air inlet pipe, other bottle neck main body is constant, and vinegar bottle just can employ, and fluid and air inlet reach desirable effect, also saves a lot of productive costs equally.Of a great variety due to liquid, just now be only list several edible liquid, non-edible liquid is as gasoline, diesel oil, automobile engine oil, lubricating fluid, chemical liquid etc., if each opens a secondary mould to produce bottle neck, the quantity of mould is very large, bring huge productive costs to manufacturing enterprise, cause great waste.
In order to make air inlet pipe and air inlet pipe base stable connection, air inlet pipe in use is avoided to come off, air inlet pipe outer wall of the present invention is provided with air inlet pipe flange, and air inlet pipe draw-in groove is provided with in air inlet pipe base, make use of elasticity of plastics and be out of shape large principle, when air inlet pipe is inserted into air inlet pipe base, flange on air inlet pipe falls into the draw-in groove inside air inlet pipe base, air inlet pipe again cannot be separated voluntarily, only when air inlet pipe could being taken out by when instrument and powerful external force, doing so avoids bottle neck to be installed to after on bottle, in the middle of the process of product long-distance transport or use, air inlet pipe oneself comes off the possibility dropping to and become foreign matter in the middle of container.
Admission port of the present invention and liquid outlet place are all provided with sealing member, can ensure the sealing of the bottle bottle neck before transport or use being packaged with liquid, liquid can not be flowed out from two opennings, during first pouring liquid, remove two sealing members simultaneously.
Partition of the present invention is that ladder channel-shaped is arranged, and form multistage backflash, admission port is arranged on the bottommost of backflash, and backflash does not have dead angle, and the residual of liquid outlet is back in the middle of container easily, and keeps bottle neck neat and tidy.

The present invention in use, when first pouring liquid, first the sealing member of liquid outlet is removed, again the sealing nail on admission port is removed, liquid outlet and admission port are all opened, with arbitrarily angled pouring liquid, internal diameter due to induction opening is less than the internal diameter of liquid outlet, liquid in bottle flows out from liquid outlet, after liquid pours out a part from liquid outlet, air pressure in bottle has diminished, the pressure that outside air produces at admission port place to be greater than in bottle liquid to the pressure on air inlet position surface, now gas enters bottle from admission port by induction opening, until inside and outside air pressure balance.In the process of pouring liquid, position due to induction opening is high and the position of liquid outlet is low, therefore, the liquid pressure at admission port place is less than the liquid pressure at liquid outlet place, air preferentially enters bottle from admission port, and achieve thoroughly being separated of fluid and air inlet, fluid will be steady, avoid the phenomenon that liquid outlet enters flow rate of liquid that air causes, the even splash of mass flow discrepancy, ensure that liquid outlet flow velocity is smooth and easy, flow is controlled.
It will be appreciated by those skilled in the art that sealing member in the present invention can play structure, the diaphragm seal being such as attached to admission port place and the sealing plug etc. be inserted in admission port of sealing function for other beyond sealing nail.Air inlet pipe of the present invention can with bottle neck body injection moulding integrated molding, also can arrange for split, the later stage use install.
The present invention makes traditional liquid outlet into a liquid outlet and an admission port, add the design that multistage backflash is beneficial to raffinate backflow, proved by a large amount of tests, particularly for less than 20 liters small packaging containers, it is smooth and easy that bottle neck provided by the invention can realize fluid, the object that flow velocity is even, flow is controlled, and possess feature with low cost.
Air inlet pipe of the present invention can be straight tube, can be also bend pipe, all can complete goal of the invention of the present invention.
The above embodiment is only the preferred embodiments of the present invention, and and the feasible enforcement of non-invention exhaustive.For persons skilled in the art, to any apparent change done by it under the prerequisite not deviating from the principle of the invention and spirit, all should be contemplated as falling with within claims of the present invention.
