Definitions
- the invention relates to a metering device for liquids, with which several preferably two liquids in precisely measured amounts with each other be merged and mixed with the characteristics of The preamble of claim 1.
- the known dosing device for dosing several liquids from who starts the invention (EP 0 448 394 A2) has at least two cylinder-piston arrangements on, each via an intake valve and a Suction line with an external liquid supply and one each Ejection line with ejection valve with a dispensing device with a mixing chamber and discharge opening are connected. Connected and with it when realizing a housing for the dosing device in this housing All parts of the metering device are arranged, while those with each other mixing liquids, in the exemplary embodiment a beverage concentrate and water, from liquid stores outside the housing via feed lines are fed.
- cylinder-piston arrangements of these Known metering devices have cylinders with very different Diameters, so that different with the same piston stroke Amounts of liquid, for example in a ratio of 1: 3 can.
- a single Drive element namely a hand lever of a drive device driven Modify lever mechanism so that the pistons with different Lever arms are moved, which then different piston strokes realized with one and the same drive movement of the drive member. Also this allows the dosing ratio of the liquids to be changed.
- the cylinder-piston arrangements of the metering device not via supply lines with the corresponding liquid stocks connected, but these cylinder-piston assemblies are more than or less commercially available bottle top dispenser (see e.g. B. DE 197 02 773 A1, DE 197 02 778 A1).
- Has a bottle top dispenser in the bottle top mechanism usually a screw-on mechanism, and in A dosing arm protruding from it integrates the suction and exhaust valves as well as the intake and exhaust lines. That's a thousand times tried, compact construction.
- Each of the bottle top dispensers is included firmly attached in the housing.
- the bottle top dispensers are therefore according to the invention used atypically, namely fixedly arranged in the housing, while the liquid storage bottles on the fixed bottle top dispensers attached by means of the bottle top mechanism, in particular be screwed on.
- blow-out device described here allows the Dispensing device either automatically after each dosing process or alternatively, if one considers it necessary, of the doses Free liquids. This can cause undesirable chemical processes for long liquid components remaining in the dispenser avoid.
- the metering device shown closed in a perspective view in FIG. 1 is intended for liquids, especially for various liquid components of disinfectants and especially for joint delivery of various components of a medically effective Disinfectant, especially a peroxide-alcohol mixture.
- the metering device shown in FIG. 1 is suitable for wall mounting Device with a support frame 1 and one attached to the support frame 1, covering the entire metering device Hood 2 executed.
- Support frame 1 and hood 2 together a housing 3.
- Fig. 1 and Fig. 2 show in connection that in the housing 3 on the support frame 1 several, in the illustrated embodiment, two cylinder-piston arrangements 4 are arranged, each with a liquid component can be dispensed exactly in doses.
- a dispenser 9 with a mixing chamber 10 that is present may be, but need not be, in which the discharge lines 7th are stirred together to form a discharge opening 11.
- the discharge opening 11 has the shape of a cannula, so that the liquid mixture can be dosed in a targeted and splash-free manner.
- Fig. 6 shows a piston 12 a Cylinder-piston arrangement 4, as they are per se for bottle-top dispensers is known (DE 197 02 773 A1, DE 197 02 778 A1) and one with the piston connected outer sleeve 12 '.
- the outer sleeve 12 ' moves with the piston 12.
- the spring force direction installed upwards, here indicated by the double arrow representing the force effect Return spring 12 ".
- This return spring 12" ensures that the piston 12th with the outer sleeve 12 'up to a height adjuster 18 predetermined stop is raised by spring force. The downward movement of the piston 12 with the outer sleeve 12 'takes place against the spring force.
- a bottle top dispenser 4 here as a typical bottle top dispenser (see the previously mentioned references).
- Every bottle top dispenser 4 has integrated the intake and exhaust valves 6, 8 and the suction and discharge lines 5, 7 and has a bottle top mechanism 15 on.
- a bottle top mechanism 15 is in most Cases a push-on cap or a screw cap that corresponds to a corresponding one Design of the neck of a liquid storage bottle 16 corresponds.
- suction line 5, which is a hose line or pipeline from the bottle top mechanism 15 into the storage bottle 16 extends downward, and the discharge line 7 in the typical form an arcuate protruding dosing arm to the delivery device 9 leads.
- the bottle top dispenser 4 each with the bottle top mechanism 15 or a corresponding component in the Housing 3, in the exemplary embodiment shown on a support plate 17 of the Support frame 1, are firmly attached, so that on the stationary bottle top mechanism 15 each bottle top dispenser 4 a liquid storage bottle 16 can be interchangeably attached.
- a liquid storage bottle 16 can be interchangeably attached.
- liquid storage bottles 16 are arranged in the housing 3 and the housing 3 for Replacing the liquid storage bottles 16 is openable.
- an embodiment which is characterized in that the bottle top mechanism 15 arranged at the edge, in particular at the bottom of the housing 3 and the liquid storage bottle 16 can be attached to it from the outside is.
- 1 and 2 show very well in connection that in the exemplary embodiment shown, where the dosed and brought together Liquid quantities are very different, the sizes of the storage bottles 16 very different for the two liquids to be mixed are.
- the illustrated embodiment applies to, for example a short-term stable peroxide-alcohol mixture with a mixing ratio of typically 1:40 peroxide and alcohol.
- Dosing equipment can also be completely different and much higher Achieve mixing ratios because you can use extremely different designs Cylinder-piston assemblies 4 can work.
- it recommends to provide that the individual, designed as a bottle top dispenser Cylinder-piston arrangements 4 as such and / or individual parts thereof against exchange parts with different dimensions and consequently different ones Dosing volumes can be exchanged.
- you can do one and the same Dosing device for very different mixing ratios convert, much more differently than you can with the other setting options (Change in stroke, change in leverage) can.
- bottle top dispenser 4 So that the bottle top dispenser 4 is not confused can, it can be provided that the bottle top mechanisms 15 of the various Bottle top dispenser 4 are designed differently, see above that a confusion-free attachment of the associated storage bottle 16 is guaranteed. How to do it in detail, for example due to different diameters of the internal threads of the bottle top mechanisms 15, is within the grasp of the specialist and does not require any here further detailed explanation.
- Bottle-top dispensers 4 with interchangeable parts for a mix-up Ensure the design of the interchangeable parts. This will ensured that not suddenly by the other dimensioning of the "inner life" the bottle top dispenser 4 completely different dosing volumes be dosed. You can do this, for example, by the coupling mechanism for the piston head of the piston 12 in the Executes outer sleeve 12 'confusion.
- you can get a confusion-proof version realize that you have the adapter required to install the micro pipetting unit in the bottle top dispenser 4 accordingly designed.
- the illustrated and preferred embodiment first shows one mechanical drive device 14, which has a lever mechanism, with the one with a uniform drive movement of a drive member 19 different working stroke of the piston 12 is achieved.
- the second embodiment shown in Fig. 5, realizes this function in that the Lever mechanism a one-sided bearing axis 20 for each protruding Actuating lever 21 per piston 12 that the cylinder-piston assemblies 4 arranged at different distances from the bearing axis 20 and that the joint actuation of the actuating lever 21st causes a different working stroke of the pistons 12.
- the distances of the cylinder-piston arrangements 4 from the bearing axis 20 are limits in this embodiment in that the housing 3 of the dosing device in any case with the wall mounting provided here cannot become as deep as you like.
- FIGS. 2 to 4 stands out therefore from a differently arranged lever mechanism.
- the lever mechanism a one-sided bearing axis 20 for a single protruding actuating lever lying transversely in the housing 3 21 for the pistons 12 of both cylinder-piston arrangements 4 having.
- the side-by-side arrangement of the cylinder-piston arrangements 4 in the housing 3 arises by itself that these differ Distances from the bearing axis 20 are.
- This will the different working stroke of the pistons 12 is realized by itself.
- There the distance between the cylinder-piston assemblies 4 in the width of the housing 3 can be much larger than in the depth of the housing 3, results such a way of a much larger dosing ratio by much to achieve more different piston strokes.
- FIG. 2 shows the bearing axis 20 on the right and opposite on the left Side of the support frame 1, a guide 22 for the operating lever 21. This is guided laterally in the guide 22 and otherwise on the piston heads held loose by a guide spring 23.
- the illustrated and preferred embodiment further shows that the Drive element 19 of the drive device 14 is an articulated in the housing 3, protruding from the housing 3, preferably bow-shaped hand lever is.
- the hand lever forming the drive element 19 can be seen in FIG. 1 the hood 2 of the housing 3 exiting at two slots 24. This hand lever can be done with the elbow as is usual in the medical field press down while putting a hand under the discharge opening 11 of the Dispenser 9 holds.
- Fig. 2 shows that the drive member 19 spring-loaded in its rest position is, namely by means of the return spring 26 recognizable on a sleeve 25. Im remaining is provided that the actuating lever 21 on the heads of the Piston 12 of the cylinder-piston assemblies 4 only rests and this piston 12 are spring-loaded in the return direction (due to the internal Return springs 12 ", Fig. 6). The return spring 26 of the drive member 19th serves to reset to the rest position.
- Fig. 4 shows that the power transmission from the bow-shaped hand lever formed drive member 19 on the operating lever 21 via a Deflection roller 27 and an actuating roller 28 lying transversely thereto, so that the mutual relative movements of the individual parts is unproblematic can be included.
- FIG. 5 shows a particularly interesting embodiment in this respect a drive device 14 of a metering device according to the invention, as the drive member 19 each cylinder-piston assembly 4, with which respective separate actuating lever 21 cooperating force introduction element 19a; 19b.
- Each force introduction element 19a; 19b is with the associated actuating lever 21 of the respective cylinder-piston arrangements 4 coupled via a lost motion connection.
- This lost motion connection is preferably adjustable and in any case in the illustrated exemplary embodiment with a return spring 26a; 26b executed.
- the force application elements 19a; 19b are crossbars in the illustrated embodiment of the bow-shaped hand lever that forms the drive member 19.
- the aim is that the dosage ratio the different liquids typically 1:20 to 1:80, is preferably about 1:40. But you can also go to much larger ones Dosage ratios come, for example one to two powers of ten greater. It is particularly preferred if a total amount of liquid per stroke from 1 to 5 ml, preferably from about 3 ml.
- blow-out device 29 in the housing 3 arranged and via a blow-out line 30 with the delivery device 9 connected is.
- the blow-out device 29 is either after each metering process can be put into operation automatically or can be chosen after a decision the operator in function.
- the illustrated embodiment shows a pressure vessel 31 that is made of compressible, preferably rubber-like material and for production a compressed air blast is compressible.
- a connection 32 for the blow-out line 30 At the top of the pressure tank 31 is a connection 32 for the blow-out line 30. Die Blow-out line 30 goes from the connection 32 in FIG. 2 to the left, located there a pressure check valve is installed. On the right there is a connection piece 32 from, there is a suction check valve. This is a clear flow direction for blow-out air is specified.
- the pressure vessel could be used for the blow-out device 29 Provide 31 as a compressed air supply, for example also as a compressed air cartridge To run. Then you would only need a valve for the compressed air pulse for a short time to open. However, this has the disadvantage that such a pressure vessel is more common must be replaced or refilled.
- the illustrated and preferred Embodiment now shows that here the elastically compressible Pressure vessel 31 from the drive member 19 after completion of the liquid metering stroke compressible with a subsequent blow-out stroke is.
- the pressure vessel 31 thus acts as a kind of air pump.
- the illustrated and preferred embodiment is distinguished in this respect further characterized in that the drive member 19 by means of the intermediate Return spring 26, which already explained above in its return function has been on the actuating lever 21 for the cylinder-piston assemblies 4 acts so that the drive member 19 with the operating lever already stationary 21, that is, after completion of the metering stroke, its drive movement continue for a certain distance while doing the blow-out stroke can.
- the embodiment shown in FIG Blow-out device 29 has a pressure lever 33, which in turn is in the blow-out stroke is pressed down by a projection 34 on the drive member 19 and with the thickened end of the elastic pressure vessel 31 like an air pump compresses. This will be on the last path all over The blow-out function is simply carried out automatically.
- a preferred embodiment that can not be seen in the drawing is also characterized with regard to the blow-out device 29 from that the blow-out line 30 at the mouth into the dispenser 9 has a check valve.
- This check valve can be used simultaneously perform the function of the pressure valve, which otherwise, as explained above, sits at port 32 on pressure vessel 31. Then you got through this Valve at the same time ensures that from the mixing chamber 10 not accidentally Liquid strikes back into the blow-out line 30.
- the mixing chamber 10 it applies that it is designed for it there are numerous suggestions in the prior art. You have to Design the mixing chamber 10 to match the liquids to be mixed and dimension. There is a wide range for this in the prior art of suggestions to which reference can be made here. In particular is it of course differs whether liquids should be mixed, which are mix easily by itself due to their chemical consistency, or whether Liquids are processed that are mixed with mechanical aids Need to become.
- a dosing device is particularly important type in question for joint delivery of various components a medically effective disinfectant, especially one short-term stable peroxide-alcohol mixture.
