Embodiment
The container of hard material, such as bottle of glass, ceramics, metal or plastic material, tank, kettle, using the side toppled over during feed
Formula, this can simply be represented with Fig. 1：Container, which is initially at stand up position → container tilts to dose location to side and kept →, to be held
Device is returned to stand up position storage.The size of tilt angle alpha is accustomed to by user, container profile, remaining liquid measure number influence,
But generally between 100-135 degree.When container is in obliquity, relatively low side (position as shown in L in Fig. 1) will claim below
For downside, higher side (position as shown in U in Fig. 1) is referred to as high side below.
Feeding coal as requested is different, and dosing cover core can have different mounting means：If had inside container enough
Its all or part, can be placed in container by space, such as Fig. 2.If interior of the container is limited, appearance can be placed on
Outside device, such as Fig. 3.No matter why not same the outward appearance that mounting means different band is come has, above and below each part, left-right relation it is constant,
Operation principle is identical, is only illustrated below by taking built-in mounting means as an example.
Embodiment 1 as shown in Figure 4, is the dosing cover core of built-in mounting means.Its agent structure is a hollow cylinder
Shape body, has sealing ring to be fitted close with bottleneck sideways, on the left of such as Fig. 4.For convenience of displaying internal structure, sealing is removed on the right side of Fig. 4
Circle, and it is labelled with each part numbers.It is visible in Fig. 4：Inner chamber is divided into upper and lower two parts, top by internal partition (4)
For surge chamber (2), bottom is measuring room (1).Drain pipe (11) positioned at downside and the air inlet pipe (12) positioned at high side will be counted
Amount room (1) is connected with outside atmosphere, positioned at the feed tube (31) and escape pipe (32) contour, positioned at high side therewith of downside
By surge chamber (2) with being connected inside container.Positioned at high side change liquid pipe (21) and ventilation pipe (22) by surge chamber (2) with
Measuring room (1) is connected.According to principle of hydrodynamics, gas is much smaller than the liquid of same fluidised form in flowing by the resistance of tube wall
Body.Therefore, the cross-sectional area of each tracheae is smaller than the liquid pipe matched with it, so that the dischargeable capacity of two chambers is maximum.
Install for the first time after dosing cover core, do once to topple over to act being initialized, the friendship of liquid, gas in initialization procedure
Principle is changed among following description, therefore is not illustrated individually.After initialization action terminates, left in surge chamber (2) a little
Hydraulically full in liquid, measuring room (1), this state is the standing state before feed every time, such as Fig. 5.Later each feed
Since this state, terminate to this state.
Fig. 6 to Figure 10 illustrates once complete feeding process, and for convenience of describing, necessary deformation has been made to each conduit positions in figure
Processing.As shown in fig. 6, when container is tilted by stand up position, the sub-fraction liquid in measuring room (1) flows into out liquid
Manage (11), extraneous air is entered at the top of measuring room (1) by air inlet pipe (12)；Liquid in surge chamber (2) then flows to low
Side.Fig. 7, when container continues to tilt, the liquid in measuring room (1) flows out to outside, measuring room (1) through drain pipe (11)
Interior liquid level reduction, extraneous air goes successively to measuring room (1) by air inlet pipe (12).In container, due to feed tube (31)
Now occur difference in height between the mouth of pipe of escape pipe (32), therefore produce the liquid in pressure differential, container through feed tube (31)
The air flowed into surge chamber (2), surge chamber (2) then enters container through escape pipe (32).Fig. 8, container lean is to finally
Feed angle and kept for a period of time, the liquid in measuring room (1) continues on through drain pipe (11) and flows out to outside, outside empty
Gas goes successively to measuring room (1) by air inlet pipe (12).Liquid in container continues to flow into surge chamber (2), when surge chamber (2)
When interior liquid level floods escape pipe (32) mouth of pipe, liquid enters escape pipe (32), and the air of the inside is all expressed into container
It is interior.Subsequently, as the fluid-tight effect that liquid level is provided, enters in container, the liquid in container is under Gravitative Loads there is no air
It may proceed to outflow a small amount of (hereinafter referred to as from flow) to surge chamber (2), as this partially liq flows out, container is internally formed negative pressure
And gradually increase, when the negative pressure just offsets remaining liq in container in the static pressure difference that the height of vertical direction is produced, in container
Liquid stop to surge chamber (2) flow, reach poised state.Now, it is empty in the wedge shape of surge chamber (2) top corner part formation one
Air gap, is the view of the air-gap from two different angles as shown in Figure 9.Managed (22) due to changing liquid pipe (21) and ventilation
The mouth of pipe is in this air-gap, and the liquid in surge chamber (2) may not flow into measuring room (1).Liquid in measuring room (1)
Body all after outflow, just there is no liquid outflow, has reached the purpose of dosing.
In surge chamber (2), the size of wedge air gap is related to the position of escape pipe (32) mouth of pipe during poised state.By the position
Put and shift to top cover (0), or bend towards downside, liquid level, which floods time of the mouth of pipe, during container lean to shift to an earlier date, and finally will appear from more
Big air-gap.Rational air-gap size is that it can just contain and changes liquid pipe (21) and (22) are managed in ventilation, adds necessary peace
Full allowance, makes the volume of surge chamber minimum, so that the volume of whole device is minimum, this needs is big according to liquid specific gravity, container
Small and height and the feeding coal that requires every time are determined.
Feed is finished, and container returns to stand up position, such as Figure 10.Now, if the liquid level in surge chamber (2) is in feed tube (31)
Under escape pipe (32) mouth of pipe, then the liquid in surge chamber will not be flowed back in container.If the liquid level in surge chamber (2) is still
On feed tube (31) and escape pipe (32) mouth of pipe, then due to feed tube (31) and escape pipe (32) the mouth of pipe now
The air being filled with same level, and two pipes in the liquid and container in liquid, therefore surge chamber (2) will form accurate steady
State, almost no liquid flows back to container in the short time.In contrast, liquid pipe (21) is changed lower than ventilation pipe (22), and ventilation
Manage (22) in back to be located in wedge air gap, now still full of the liquid in air, therefore surge chamber (2) and metering
Air formation undefined structure in room (1), liquid flows rapidly into measuring room (1) from liquid pipe (21) is changed, and air is then from ventilation
Manage (22) to enter in surge chamber (2), until measuring room (1) is hydraulically full.Make surge chamber (2) replenisher every time during design
It is equipped with, than measuring room (1) dischargeable capacity slightly many liquid, a little liquid being retained in final buffer room (2) after body.Now,
The replying state of measuring room (1) and surge chamber (2) is to identical with Fig. 5.
The present embodiment is suitable for the harder container of quality, such as glass container, ceramic vessel, canister and hard plastic vessels.
This kind of container deformation is small, from flow less, therefore the method that can be used in reservation wedge air gap in surge chamber (2) prevents liquid from existing
Measuring room (1) is flowed into during feed.
Embodiment 2 as shown in figure 11, applies to the dosing cover core of the softer container of quality (such as thin plastic bottle).It is this kind of
Container is when tilting feed, because contraction distortion is larger thus larger from flow caused by negative pressure in hand-held strength and container,
According to the mode for retaining wedge air gap the volume of surge chamber (2) will be caused excessive, that is, whole device volume is excessive.This reality
Apply example use with the substantially identical structure of above-described embodiment 1 and principle, but change liquid pipe (21) and ventilation manage (22) top
Portion has installed miniature ball float (211,221) additional.The effect of ball float is that liquid level rises to float-level when container lean is to dose location
Put, the buoyancy of liquid makes ball float floating withstand the mouth of pipe, so as to prevent the liquid in surge chamber (2) from entering measuring room (1).Work as appearance
When device is returned to stand up position by obliquity, the buoyancy of liquid makes ball float leave the mouth of pipe again, makes surge chamber (2) and measuring room (1)
Between formed liquid, gas switching path.
Embodiment 3 shown in Figure 12, is on the basis of embodiment 1 or embodiment 2, to increase the regulatory function of feeding coal.Specifically
Implementing method is that drain pipe (11) is changed into double-decker：It is liquid outer tube (111) and go out liquid inner tube (112), goes out liquid outer tube
(111) it is fixed on top cover (0) and partition (4) there is provided sealing function, goes out liquid inner tube (112) and go out liquid outer tube (111)
Coordinate close, but can be turned an angle in liquid outer tube (111) is gone out.Go out liquid inner tube (112) for L-shaped structure, during rotation,
Nozzle position positioned at L-shaped structure bottom changes therewith.When container lean is to dose location, such as Figure 13, measuring room (1)
The liquid for inside being higher than liquid inner tube (112) mouth of pipe flows out under gravity or siphonage through going out liquid inner tube (112), remaining liquid
Remain in measuring room, reach the purpose for changing feeding coal within the specific limits.On top cover (0), going out liquid outer tube (111)
Surrounding has scale (113), coordinates with going out the mark (114) in liquid inner tube, indicates rotational angle or corresponding feeding coal.Most
During big feeding coal, the liquid in measuring room (1) is all discharged, and this practical example still has the measuring accuracy of maximum.In centre position,
Inclined angle has an impact to the liquid measure for ultimately residing in measuring room (1) during due to feed, and measuring accuracy can be reduced, but because of everyone
There is relatively-stationary motor habit, so remaining to provide good reference for user.
