Summary of the invention

Above-mentioned exist following problems in first example.

1. when the residual spray mixture in using particularly in container is few, if careless by container to reversed dip, then can siphon be caused immediately to interrupt.Now, again must produce siphon state can continue to use.

On producing during siphon state once, the siphon because of last time is interrupted and the liquid residued in stream hinders the generation of siphon state next time sometimes.

Like this, operation syphon tube temporarily being taken off from container the liquid disposed in stream must just be carried out.

Sometimes also same situation can be produced when siphon state adds liquid to reuse after terminating once being taken by the liquid in container.

2. in order to produce siphon state, must tilt, until the liquid level in container arrives the adjacent edges of container.Required attention alters a great deal because of the difference of the intensity of capillary force, and this operation needs careful carrying out.

The environment rocked in car etc., liquid level are difficult to the dim place of seeing clearly or cause hand shaking because of cold or nervous etc., make liquid spill sometimes, realizability aspect also has problems.

3. produce the syphon tube internal surface reaching the capillary force of siphon and need to a certain degree above hydrophily, operable material exists restriction.

The geomery of pipe internal surface also can affect and produce the ease of siphon state, therefore there is the problem that processing method, size management etc. manufacture.

4. as previously described, the hydrophily of syphon tube internal surface can affect the ease of use, and by dirty impact, siphon state also can be difficult to produce.Cleaning can be restored, as long as boil.

But when wanting to reinstate with other feeders one washing agent and cleaning, the curved section due to pipe top is flat, therefore, even tiny brush also some can be difficult to cleaning.

The present invention makes in view of the above problems, has carried out following change at first example.

A. center liquid chamber is set in the stream of outside of containers, to make having stable behavior.

Center liquid chamber was be arranged on to utilize on the conduit transport path of the liquid of difference of height to be used in the past always.The impact that the flow variation that the flowing state cushioning the liquid in upstream or downstream causes, air are mixed into is to make flow stabilizes.

In the present invention, for the problem of above-mentioned 1., there is the effect postponing to produce siphon interruption.

Time in use by container reversed dip, if produce the adverse current exceeded than siphonal lowest order part also amount of liquid downstream, then gas can get into lowest order part and cause siphon to be interrupted.

By the lowest order part from container outflow road, center liquid chamber is set to downstream side, the reflux flow needed for siphon interruption can be increased.As a result, following characteristic can be obtained: interrupt if the adverse current of short time then can not produce siphon.

Center liquid chamber can be in use can open at upper storage gas, the sealed mode that also can be full of by liquid.In the former case, it is desirable to be communicated with air in the position higher than imagination liquid level height.But, also sometimes need the pump mode passing through adopted the next item down not hinder the flow resistance of pumping function degree to gas exerts.

B. pump-unit is set at outside of containers, makes to produce negative pressure in siphon guide to produce the mode of siphon state.

About the method using pump-unit to produce siphon state, there has been proposed multiple schemes such as such as patent documentation 2.

Also attraction is forcibly carried out when residual liquid to enter siphon state in syphon tube.Therefore, the liquid residue taken notice of in pipe is not needed.

In addition, as long as the airtight and intensity of necessity, then form the material of siphon guide and the ease irrelevant of generation siphon state.Can from unrestricted choice the material with the temperature performance, resistance to fluidity etc. that adapt to purposes.

Meanwhile, vpg connection, particularly the design freedom of the curved section at syphon tube top also will increase.The difficulty of manufacture can be reduced, and the design of the cleaning considering user can be carried out.

The curved section at syphon tube top adopts the formation of the bending part at the obtuse angle that is tightly connected, and can carry out with sponge etc. the internal diameter that cleans by making to be configured in stream, cleaning property significantly improves.In first example, when stream under the state at tilt container is in the position than high more than several millimeters of liquid level, siphon state cannot be produced.And in the present invention using pump-unit, can enlarged inner diameter and no problem.

By strengthening the internal diameter at syphon tube top, the flow path resistance of syphon tube entirety incidentally can also be reduced.With compared with first example, the fast application of take-off speed easily can also be tackled.

Wish: the volume of the attraction Capacity Ratio siphon guide of pump is large, but with not excessive compared with the different and different necessary capacity of pump form.Thus, except solving as described above except the problem 2,3,4 of first example, by mistake make liquid flow out when can also reduce generation siphon state or invade the inconvenience of external pump.

The same with many conventional examples, siphon state cannot be transferred to because of the internal diameter of sloping portion of outside of containers of siphon guide and the relation of the attraction speed of pump sometimes.This is because top remains large quantity of air and makes liquid first fall.Dealt with by the attraction speed that improves pump or the internal diameter that reduces sloping portion.

Also be a rational scheme to above-mentioned center liquid chamber carried wet function.

Above-mentioned patent documentation 2 grade is also same in the formation of stream.In the formation of patent documentation 2 form, container (tank) is fixed, therefore, changes the height of conveying end when change take-off speed.Such as consider to take out hot water to infuse the situation of coffee from container.While make the distance of Hu Zui and coffee powder be close to a certain degree, the speed of injection rate be changed.In the formation of patent documentation 2 form, the coffee filter bowl side and the moving up and down of Hu Zui that make to have put into coffee powder are correspondingly moved for this reason.Have during a small amount of drippage and be fine like this, but, be then difficult to operation when drainage uses greatly large-sized flange suede filter etc.Formation of the present invention is applicable to this situation.Be only while make Hu Zui keep phase co-altitude, the inclination of change container, even if filter bowl is sidelong to put motionlessly also easily change speed.Can transportability owing to taking out that the container of side has, therefore, it is possible to the scope be suitable for is wide, also comprise the situation injected object and be difficult to movement.

As described above, the present invention can realize following liquid taking-up syphon tube: even if also can bring into use simply in the presence of a harsh environment, interrupt even some crude use is also less likely to occur siphon, the cleaning after using also easily and also relevant to material, geomery manufacture and design on restriction few.

Embodiment 1

Fig. 1 is the stereogram representing the state syphon tube of embodiments of the invention 1 being installed on container, and Fig. 2 is the sectional view of the liquid flow path of same state.

At this, 1 is the cup as liquid-container, and 13 is siphonal housings, doublely does center liquid chamber of the present invention and pump.Housing 13 by the internal tank of the siphon guide 2 shown in Fig. 2 divide 111 and the alar part 110 of housing 13 be installed on cup 1.

14 is conveying ends of liquid, is flexible pipe.15 is frameworks, conveying end 14 is fixed on the height of the edge degree of cup 1, and as will be explained later, the pumping function of auxiliary shell 13.

As shown in Figure 2, siphon guide 2 divides 12 to be tightly connected and the formation that formed for internal tank being divided 111 with external container, guarantees easy to clean.

Housing 13 is the containers of the softness connecting main body 114 and cover 112 and formed.Siphon guide 2 is assembled by embedding etc. with the form running through cover 112.The root of conveying end 14 is by the outflow opening be tightly connected in the bottom of housing body 114.

Housing lid part 112 also has the aperture 113 for being communicated with air.But, for housing body 114 and lid 112 connection and cover 112 and siphon guide 2 connection for, as long as be suitably communicated with air, then aperture 113 is optional.

To adopt when not using and siphon guide 2, conveying end 14, framework 15 can be unloaded and the form being accommodated in housing 13 is conducive to moving.The shape of illustrated each parts, to form be to be described, and in fact adopts that ease of use is best, the shape that is best suited for manufacture and segmentation form.

In the Fig. 2 representing original state, liquid 0 is just present in cup 1.In siphon guide 2, also there is liquid level 102 at roughly identical with the liquid level 101 in cup 1 height.

Next, the pumping function auxiliary movement of framework 15 is described with reference to Fig. 3.

With Fig. 3 (A), formation is described.115 is side plates of framework 15 both sides, from left and right covering shell main body 114 and conveying end 14.Side plate 115 has guide element 116,117, tine 119 and work time the pad 118 of softness that the pipe of conveying end 14 is flattened.Under the effect of housing body 114 and spring 120,121, side plate 115 keeps the interval of the width degree of housing body 114 usually abreast.

Utilize Fig. 3 (B), (C) illustrate the action of the framework 15 in above formation.For the ease of observing, eliminate the diagram of spring 120,121.

When the direction of the white arrow along Fig. 3 (B) presses side plate 115 equably, first housing body 114 is crushed.During further pressing, guided member 116,117 guides, the narrower intervals of side plate 115, and very fast conveying end 14 is pressed by pad 118 and inaccessible.And then tine 119 engages and reaches the state of Fig. 3 (B).

At this, when removing the power of white arrow, under the effect of housing body 114 with the recuperability of spring 120,121, side plate 115 will return to origin-location.But owing to being hindered by tine 119, the recovery in figure left side is delayed.When reaching the state of Fig. 3 (C), tine 119 is thrown off, and returns to the state of Fig. 3 (A) afterwards.In the process of Fig. 3 (B) to (C), continue the blocked state of conveying end 14.

Utilize above formation that the action of embodiment 1 is described.

In order to the state from Fig. 1 and 2 produces siphon state, first user presses framework side plate 115.

Thus, housing body 114 is crushed, and inner gas spills into outside by the aperture 113 of also not inaccessible conveying end 14 and housing lid 112.Very fast side plate 115 is forced into the end, and now, conveying end 14 is inaccessible and reach the state of Fig. 3 (B).By this action, liquid side can not change significantly, if remove vibration, then stream sectional view is exactly that Fig. 2 is such.

Next, when user discharges side plate, during till reaching the state of Fig. 3 (C), the volume being in the situation lower shell body main body 114 of blocked state at conveying end 14 increases.Under the effect of the negative pressure produced in housing 13 and siphon guide 2, the liquid 0 in cup 1 is attracted.Liquid 0 is full of siphon guide, produces siphon state, becomes the flowing path section shown in Fig. 4.The liquid level 102 be in siphon guide 111 enters in housing body 114, forms liquid level 103 transiently.The recovery speed of gas to housing body 114 flowed into from aperture 113 has resistance, and therefore, the suction of liquid 0 is preponderated.After the recovery of housing body 114 terminates, gas is circulated by aperture 113, and the liquid level 103 in housing body 114 is close to the height identical with the liquid level 101 in cup 1.

When tine 119 is thrown off, when side plate 115 returns to original state, the obturation of conveying end 14 is also removed, and stream sectional view as shown in Figure 5.The liquid level 104 of the liquid level 103 in housing body 114, conveying end 14 side is all in the height roughly the same with the liquid level 101 in cup 1, reaches stable.

After syphon tube is installed on cup, in order to produce siphon state, the handle 911 of pump 910 is pressed to cup 1 side by user.

In the compression process of pump 910, liquid 0 is only in cup 1.During pump pressure contracting, valve 912 is in open mode, and thus gas is discharged from the opening on center liquid chamber top and conveying end, and the liquid level 902 therefore in siphon guide 2 also can not change significantly.If remove vibration, be then in roughly identical with the liquid level 901 in cup 1 height.

Figure 31 represents that user removes the compression of pump 910, the sectional view of the status of processes that pump 910 restores.The negative pressure that pump 910 produces makes also to produce negative pressure in siphon guide 2,92, and membrance valve 912 becomes closed condition, and is exported to outside cup 1 by liquid 0.The liquid 0 entering into pump 910 from siphon guide 2 retains in pump, forms such as liquid level 903.When the internal diameter of siphon guide 92 large to a certain degree, also there is a part of exchange in the liquid in pump and the gas in siphon guide 92, forms such as liquid level 904,905.

When the recovery of pump 910 roughly completes and negative pressure is removed, valve 912 becomes open mode.Now, by retaining in the amount of the liquid 0 in pump 910, the potential energy of the liquid in cup 1 outside passages is dominant, liquid 0 is declined towards siphon guide 92 times extreme directions.If the internal diameter of siphon guide 92 is not excessive, then gas can not enter against the decline of liquid 0, thus produces siphon state.According to the difference of the conditions such as pump shape, the gas in pump 910, siphon guide 2,92 is also all discharged to center liquid chamber 93 or take-off pipe 94 sometimes.

Figure 32 be produce siphon state after representing starting action and stable after the sectional view of state.It is the example that stream top remains the pressure siphon state of gas.Liquid level 906 in center liquid chamber 93 is all in the height identical with the liquid level 901 in cup 1 with the liquid level 907 in take-off pipe 94.The gas residued in stream forms the liquid level 908 in siphon guide 2 and the liquid level 909 in pump 910.As mentioned above, if gas is fully drained, then become complete siphon state, liquid level 908,90 disappears.

Figure 33 with Figure 34 be siphon in stable condition after tilt to carry out the sectional view of the taking-up of liquid 0 together with cup 1.

Figure 33 is the less situation of the inclination of cup 1.When making conveying end tilt to the position of liquid level 901 degree in cup 1, the drippage 9078 of liquid will be there is.Liquid level 9066 in center liquid chamber 93 becomes identical with liquid level 901 or slightly low height.In siphon guide, remain gas on the top of siphon guide 2 and pump 910, and form the supply road of liquid 0, become such as 9099 such liquid levels.

Figure 34 is the situation that the inclination of cup 1 is larger.When making conveying end tilt to the position lower than the liquid level 901 in cup 1, produce the taking-up stream 9079 of liquid.Liquid level 9067 in center liquid chamber 93 lower than the liquid level 901 in cup 1 and higher than conveying end, is the height of centre because of the condition of flow path resistance.In siphon guide, be the state of the liquid stream pressing gas of liquid 0, become such as 9098 such liquid levels.Also gas is pressed by liquid stream and is discharged to center liquid chamber 93 at this moment sometimes.

According to the present embodiment, after syphon tube is installed on cup, siphon state can be produced by operating pumps 910.Can adopt and very simply form.In addition, pointing compression as utilizing two, discharging the mode of such as pump, if make syphon tube to be mounted on the action of container and pump operated interlock, then ease of use will improve further.Pump 910 also can be arranged in the below on the lower, position than figure.When pump 910 is in the position lower than the liquid level 901 in cup 1, can produce siphon state to the recovery of pump 910 terminates, the chance of complete siphon increases always.Valve 912 also can be arranged in the top more top than the position of figure.The optimum position of option and installment between the lower end of siphon guide 92 and pump 910 and valve mode is also best valve.

As application, also can be configured to, by increasing one-way valve in the upstream of pump 910, produce siphon state with lam-oil pump type multi-pass operation pump 910.Pump 910 miniaturization can also be made, in addition, also pump can be configured on the top of siphon guide.

Center liquid chamber 93 is the open of in use top memory gas.Also can lid be set, but if top is airtight, then the liquid level sometimes in liquid chamber does not rise and makes the taking-up stream of liquid 0 unstable, therefore wishes suitably to be communicated with air.

If center liquid chamber 93 and take-off pipe 94 adopt the formation that can confirm inner liquid level from outside, then can be used as the mark identifying residual spray mixture during horizontal.

Embodiment 9 in the same manner as in Example 6, is the configuration example making siphon guide have pumping function, but, according to condition, reach the example application that the stroke producing siphon state does not all depend on the effect of pumping function.Only make to produce negative pressure in siphon guide.Center liquid chamber also can be sealed mode.

Although the description of the example making pump 910 self compress, discharge, but, utilize other external pump to carry out the mode attracted also can form the syphon tube of same principle as simple liquid storeroom pump 910.Now, in the same manner as in Example 8, for being made the configuration example producing negative pressure in siphon guide by external pump, but the stroke reaching generation siphon state with the difference of condition does not all depend on that the effect this point of pumping function is identical.
