Description

Die Erfindung betrifft eine Vorrichtung sowie ein Verfahren zum Erzeugen von Rauchgas-Gemischen für chemische, physikalische, biologische und/oder In-Vitro-Untersuchungen.The invention relates to a device and a method for producing flue gas mixtures for chemical, physical, biological and / or in-vitro investigations.

Bei den herkömmlichen Vorrichtungen und Verfahren dieser Art, wie sie beispielsweise aus der Berauchungsapparatur Typ "Hamburg II" der Anmelderin oder aus der Druckschrift US-A-3 476 119 bekannt sind, wird eine Karussell-Abraucheinrichtung für Zigaretten verwendet, die nach dem rotierenden Prinzip arbeitet. Über einen konstanten Volumenstrom, der mittels einer einzigen für die gesamte Einrichtung vorgesehenen Vakuumpumpe erzeugt wird, wird jeweils eine der Zigaretten abgeraucht. Die Möglichkeit das Rauchgas zu verdünnen, ist - wenn diese Möglichkeit überhaupt benötigt wird - bei dieser Vorrichtung sowohl hinsichtlich des Verdünnungsgrads als auch der Verdünnungsgenauigkeit sehr begrenzt. Darüber hinaus erfordern die Verdünnungsvorgänge einen erheblichen Zeitaufwand.In the conventional devices and methods of this kind, as for example from the Berauchungsapparatur type "Hamburg II" by the applicant or from the publication US-A-3 476 119 are known, a carousel-smoking device is used for cigarettes, which operates on the rotating principle. By means of a constant volume flow, which is generated by means of a single vacuum pump provided for the entire device, one of the cigarettes is smoked in each case. The possibility of diluting the flue gas, if this possibility is ever needed, is very limited in this device both in terms of the degree of dilution and the accuracy of dilution. In addition, the dilution processes require a considerable amount of time.

Die Firma Pieter van Weenen & Co. GmbH, Gutach, bietet einen Rauchroboter an, mit der jeweils nur eine Zigarette abgeraucht werden kann. Hinsichtlich der Verdünnungsmöglichkeit des abgerauchten Gases ist die bekannte Anlage auf vier fest eingestellte Verdünnungsstufen beschränkt.The company Pieter van Weenen & Co. GmbH, Gutach, offers a smoking robot with which only one cigarette can be smoked at a time. With regard to the possibility of dilution of the vaporized gas, the known plant is limited to four fixed dilution stages.

Die Druckschrift EP-A-1 431 746 zeigt und beschreibt eine Rauchvorrichtung mit einer einzigen Pumpe für das Abrauchen mehrerer Zigaretten gleichzeitig und im Parallelbetrieb, wobei nur eine Pumpe vorgesehen ist. Über ein 3/2-Wege-Ventil wird das abgerauchte Rauchgas an eine Verdünnungseinheit zur weiteren Verwendung abgegeben.The publication EP-A-1 431 746 shows and describes a smoking device with a single pump for the smoking of several cigarettes simultaneously and in parallel operation, with only one pump is provided. Via a 3/2-way valve, the exhausted flue gas is delivered to a dilution unit for further use.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Erzeugen von Rauchgas-Gemischen zu schaffen bzw. ein Verfahren hierzu anzugeben, mit dem mehrere Zigaretten gleichzeitig abgeraucht werden können. Darüber hinaus soll das Rauchgas in einem breiten Bereich genau, stufenlos und insbesondere schnell verdünnt werden können.The invention has for its object to provide a device for generating flue gas mixtures or to provide a method for this purpose, with the multiple cigarettes can be smoked simultaneously. In addition, that should Flue gas can be accurately, continuously and in particular quickly diluted in a wide range.

Ausgehend von einer herkömmlichen Vorrichtung zum Erzeugen von Rauchgas-Gemischen mit einer Tabak-Abraucheinrichtung, einer Pumpe und einer Rauchgas-Mischeinrichtung wird die gestellte Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Starting from a conventional device for producing flue gas mixtures with a tobacco smoking device, a pump and a flue gas mixing device, the object is achieved by the features of claim 1. Advantageous embodiments of the invention are specified in the subclaims.

Durch die erfindungsgemäße Verwendung von wenigstens zwei Mischeinheiten ist es möglich, nicht nur gleichzeitig mehrere, auch unterschiedliche Tabakprodukte zu rauchen, sondern auch unterschiedliche Rauchgas-Gemische, insbesondere unterschiedliche Verdünnungsgrade zu erzeugen.By using at least two mixing units according to the invention, it is possible not only to smoke several, but also different tobacco products at the same time, but also to produce different flue gas mixtures, in particular different degrees of dilution.

Gemäß einer vorteilhaften Ausführungsform der Erfindung ist die Pumpe jeder Mischeinheit sowohl zum Rauchen des Tabakprodukts als auch zum Mischen bzw. Verdünnen des Rauchgases vorgesehen. Darüber hinaus ist die Pumpe gemäß einer weiteren Ausführungsform auch zum Ausstoßen des verdünnten Rauchgases einsetzbar.According to an advantageous embodiment of the invention, the pump of each mixing unit is provided both for smoking the tobacco product and for mixing or diluting the flue gas. In addition, according to another embodiment, the pump can also be used for ejecting the diluted flue gas.

Vorzugsweise ist die Pumpe eine Kolbenpumpe, die insbesondere einen Schrittmotor zum Pumpenantrieb aufweist. Durch die Steuerung des Schrittmotors ist eine stufenlose Steuerung des Rauchgas- bzw. Rauchgas-Gemisch-Volumens möglich, so dass auf einfache Weise ein sehr genaues, stufenloses und schnelles Verdünnen des Rauchgases in Zusammenhang mit dem Abrauchen des Rauchgases möglich ist.Preferably, the pump is a piston pump, which in particular has a stepper motor to the pump drive. By controlling the stepping motor stepless control of the flue gas or flue gas mixture volume is possible, so that in a simple way a very accurate, continuous and rapid dilution of the flue gas in connection with the fuming of the flue gas is possible.

Das Ventil ist vorzugsweise ein Mehrwegeventil, das gemäß einer besonders vorteilhaften Ausführungsform der Erfindung folgende Ventilwege aufweist:

  • einen Ventilweg zum Ansaugen des Rauchgases,
  • einen Ventilweg zum wenigstens teilweisen Ausstoßen des angesaugten Rauchgases,
  • einen Ventilweg zum Ansaugen von Frischluft und
  • wenigstens einen Ventilweg zum Ausstoßen des aus Rauchgas und Frischluft gebildeten Gasgemisches.
The valve is preferably a multi-way valve which, according to a particularly advantageous embodiment of the invention, has the following valve paths:
  • a valve path for sucking the flue gas,
  • a valve path for at least partially expelling the sucked flue gas,
  • a valve path for the intake of fresh air and
  • at least one valve path for ejecting the gas mixture formed from flue gas and fresh air.

Aufgrund der Gestaltung des Ventils in der genannten Weise ist es möglich, mit einem Ventil nicht nur das Rauchen des Tabakprodukts vorzunehmen, sondern auch das dabei entstehende Rauchgas in einer einfachen Baueinheit bei einfacher Handhabung schnell und in einem großen Bereich zu verdünnen. Vorzugsweise ist dabei jeder der Ventilwege mit der Pumpe verbunden. Das Ventil weist vorzugsweise vier Ventilstellungen und fünf Anschlüsse auf, und ist vorzugsweise ein 5/4-WegeVentil.Due to the design of the valve in the manner mentioned, it is possible with a valve not only make the smoking of the tobacco product, but also to dilute the resulting flue gas in a simple unit with easy handling quickly and in a large area. Preferably, each of the valve paths is connected to the pump. The valve preferably has four valve positions and five ports, and is preferably a 5/4-way valve.

Bei den herkömmlichen Rauchmaschinen wird das Rauchkondensat in einer Falle aufgefangen, das zwischen Zigarettenhalter und Pumpe angeordnet ist. Nur die Gasphase des Rauchs gelangt in die Pumpe und wird nach dem Ende des Zugs über ein Ventil in den Außenraum geblasen. Wird dagegen z.B. für In-Vitro-Versuche der volle Rauch eines Tabakprodukts - gegebenenfalls verdünnt - benötigt, gelangen die Partikel und Kondensate des Rauchgases vermehrt auch in das Ventil und die Pumpe. Daher ist ein Ventil mit Strömungskanälen gleichen Querschnitts besonders vorteilhaft, um Kondensatniederschläge und Verschmutzungen zu vermeiden.In the conventional smoking machines, the smoke condensate is collected in a trap located between the cigarette holder and the pump. Only the gas phase of the smoke gets into the pump and is blown into the outer space via a valve after the end of the train. In contrast, if e.g. For in-vitro experiments the full smoke of a tobacco product - if necessary diluted - needed, the particles and condensates of the flue gas increasingly come into the valve and the pump. Therefore, a valve with flow channels of the same cross section is particularly advantageous in order to avoid condensate precipitation and contamination.

Vorzugsweise ist das Ventil ein Drehschieber-Ventil, dessen Drehschieber mittels eines Schrittmotors zuverlässig und positionsgenau verstellbar ist.Preferably, the valve is a rotary valve, the rotary valve by means of a stepper motor is reliably and accurately adjustable position.

Gemäß einer weiteren sehr vorteilhaften Ausführungsform der Erfindung greifen wenigstens zwei Rauchgas-Mischeinheiten gleichzeitig auf eine abzurauchende Zigarette zu, so dass gleichzeitig mehrere Versuche zeitsparend durchgeführt werden können, wobei die Rauchgase dabei zusätzlich unterschiedlich verdünnt werden können.According to a further very advantageous embodiment of the invention, at least two flue gas mixing units simultaneously access a cigarette to be clogged, so that several tests can be carried out simultaneously to save time, wherein the flue gases can additionally be diluted differently.

Gemäß einer besonders vorteilhaften Ausführungsform der Erfindung greifen jeweils wenigstens zwei Rauchgas-Mischeinheiten gleichzeitig auf jeweils unterschiedliche Rauchprodukte, beispielsweise unterschiedliche Zigarettensorten, zu. Auf diese Weise ist es möglich, nicht nur mehrere Zigaretten gleichzeitig, also zeitsparend, sondern auch unterschiedliche Zigarettensorten gleichzeitig und zeitsparend zu rauchen und deren Rauchgase gleichzeitig ggf. auch unterschiedlich zu verdünnen, zu analysieren oder für unterschiedliche Versuchszwecken einzusetzen.According to a particularly advantageous embodiment of the invention, in each case at least two flue gas mixing units simultaneously access different smoke products, for example different types of cigarette. In this way it is possible not only to smoke several cigarettes at the same time, thus saving time, but also different types of cigarettes simultaneously and time-saving and at the same time, if necessary, also to dilute, analyze or use their flue gases differently for different experimental purposes.

Bei der erfindungsgemäßen Vorrichtung sind die zu rauchenden Tabakprodukte in Tabakprodukt-Haltern eines rotierenden Rauchkarussells angeordnet.
Dadurch kommt die Anlage mit jeweils nur einem Dichtheitstester, einem Anzünder, einer Stummel-Längenabtastung, einem Stummelzieher und einer Ladevorrichtung aus. Lediglich die Pumpen sind entsprechend der Anzahl der Rauchgas-Mischeinheiten mehrfach vorhanden. Bei gleichzeitiger Verwendung unterschiedlicher Zigarettensorten ist darüber hinaus eine entsprechende Anzahl von Zigarettenmagazinen erforderlich.In the device according to the invention, the tobacco products to be smoked are arranged in tobacco product holders of a rotating smoking carousel.
As a result, the system comes out with only one leak tester, one lighter, one stub length scan, one stub-puller and one loader. Only the pumps are multiple according to the number of flue gas mixing units. When used at the same time Different types of cigarettes, moreover, a corresponding number of cigarette magazines is required.

Die gestellte Aufgabe wird ebenfalls durch ein Verfahren gelöst, wie es in Anspruch 14 angegeben ist. Vorteilhafte Ausführungen des Verfahrens sind in den Unteransprüchen 15 bis 18 angegeben.The object is also achieved by a method as indicated in claim 14. Advantageous embodiments of the method are specified in the subclaims 15 to 18.

Die Vorteile entsprechen denen der erfindungsgemäßen Vorrichtung und ermöglichen die beliebige, stufenlose, genaue und schnelle Verdünnung von Rauchgasen.The advantages correspond to those of the device according to the invention and allow the arbitrary, stepless, accurate and rapid dilution of flue gases.

Besonders vorteilhaft ist eine Ausführungsform des erfindungsgemäßen Verfahrens, bei dem das Rauchen des Tabakprodukts sowie das Ansaugen und Ausstoßen des Rauchgases und/oder der Rauchgas-Gemische gemäß der Verfahrensschritte a) bis e) mit einer einzigen Pumpe durchgeführt wird. Der apparative Aufwand ist daher gering und die Funktionsweise einfach.Particularly advantageous is an embodiment of the method according to the invention, in which the smoking of the tobacco product and the suction and discharge of the flue gas and / or the flue gas mixtures according to the process steps a) to e) is carried out with a single pump. The equipment cost is therefore low and the operation is simple.

Sehr vorteilhaft ist es, wenn die gewünschte Verdünnung des vom Tabakprodukt abgesaugten Rauchgases durch das ausgestoßene Volumen des Rauchgases und/oder des Rauchgas-Gemisches und durch das angesaugte Frischluftvolumen gemäß den Schritten a) bis e) erfolgt. Die Verdünnungsgrade sind durch die Steuerung des Hubvolumens besonders genau, schnell und stufenlos durchführbar.It is very advantageous if the desired dilution of the exhaust gas sucked from the tobacco product is effected by the ejected volume of the flue gas and / or the flue gas mixture and by the intake fresh air volume according to steps a) to e). The degrees of dilution are particularly precise, fast and infinitely variable by controlling the stroke volume.

In diesem Zusammenhang ist es besonders vorteilhaft, wenn die angesaugten und ausgestoßenen Gas- und Gasgemischvolumina durch das Hubvolumen und/oder die Anzahl der Hübe einer Kolbenpumpe gesteuert werden. Ein Schrittmotor für die Steuerung des Hubvolumens ist dabei von besonderem Vorteil.In this context, it is particularly advantageous if the aspirated and ejected gas and gas mixture volumes are controlled by the stroke volume and / or the number of strokes of a piston pump. A stepper motor for the control of the stroke volume is of particular advantage.

Die Erfindung sowie weitere Merkmale und Vorteile derselben werden bzw. werden nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die einzige schematische Zeichnung erläutert.The invention as well as other features and advantages thereof will be explained below with reference to an embodiment with reference to the single schematic drawing.

Die Figur zeigt ein Rauchkarusell 1 mit beispielsweise vier äquidistant angeordneten Zigarettenhaltern 1-a, 1-b, 1-c, 1-d, die beispielsweise in einem Zeittakt von 15 Sekunden zusätzlich zur Rauchposition 2 an Positionen z.B. für die Glutdetektierung, die Stummelziehung und den Ladevorgang gedreht werden. Bei diesem Ausführungsbeispiel gelangt also pro Minute jeweils dieselbe Zigarette an dieselbe Position, z.B. an die Rauchposition 2, so dass für jede Zigarette pro Minute ein Zug abgeraucht wird.The figure shows a smoking carousel 1 with, for example, four equidistantly arranged cigarette holders 1-a, 1-b, 1-c, 1-d, for example, in a time interval of 15 seconds in addition to the smoking position 2 at positions e.g. for the ember detection, the stump extraction and the charging process are turned. Thus, in this embodiment, the same cigarette arrives at the same position per minute, e.g. to the smoking position 2, so that for each cigarette a train is smoked per minute.

Erfindungsgemäß ist mit der Rauchposition 2 nicht nur eine Pumpe, sondern es sind mehrere Pumpen 4-1, 4-2, 4-3, 4-4 - im vorliegenden Ausführungsbeispiel vier Pumpen über Schläuche oder Kanäle 3-1, 3-2, 3-3, 3-4 - verbunden. Zwischen der Rauchposition 2 und der jeweiligen Pumpe 4-1, 4-2, 4-3, 4-4 ist jeweils ein 5/4-Wege-Ventil 5-1, 5-2, 5-3, 5-4 vorgesehen, das fünf Anschlüsse oder Öffnungen S, P, C, E und F aufweist.According to the invention with the smoke position 2 not only a pump, but there are several pumps 4-1, 4-2, 4-3, 4-4 - in the present embodiment, four pumps via hoses or channels 3-1, 3-2, 3rd -3, 3-4 - connected. Between the smoke position 2 and the respective pump 4-1, 4-2, 4-3, 4-4, a 5/4-way valve 5-1, 5-2, 5-3, 5-4 is provided in each case, which has five terminals or openings S, P, C, E and F.

Gemäß dem vorliegenden Ausführungsbeispiel sind die Pumpen 4-1, 4-2, 4-3, 4-4 Kolbenpumpen, die jeweils mittels nicht dargestellter Schrittmotoren betrieben werden, und die jeweils über einen Anschluss P mit dem jeweiligen Ventil 5-1, 5-2, 5-3, 5-4 verbunden sind.According to the present embodiment, the pumps are 4-1, 4-2, 4-3, 4-4 piston pumps, each operated by means not shown stepper motors, and each via a port P to the respective valve 5-1, 5- 2, 5-3, 5-4 are connected.

Das jeweilige Ventil 5-1, 5-2, 5-3 , 5-4 ist über jeweils einen Anschluss C und eine Leitung 6-1, 6-2, 6-3, 6-4 mit einer Kammer 7-1, 7-2, 7-3, 7-4 verbunden, die das jeweilige in der gewünschten Weise verdünnte Rauchgas zu Versuchs- oder Untersuchungszwecken aufnimmt.The respective valve 5-1, 5-2, 5-3, 5-4 is connected via a respective connection C and a line 6-1, 6-2, 6-3, 6-4 with a chamber 7-1, 7 -2, 7-3, 7-4, which receives the respective diluted in the desired manner flue gas for experimental or investigation purposes.

Der Anschluss E des jeweiligen Ventils 5-1, 5-2, 5-3, 5-4 ist jeweils mit einer Auslass-Leitung 8 zum Ausstoßen wenigstens eines Teils des Rauchgases oder eines Rauchgas-Gemisches verbunden, während der jeweilige Anschluss F mit einer Frischluftleitung 9 zum Ansaugen von Frischluft in Verbindung steht.The port E of the respective valve 5-1, 5-2, 5-3, 5-4 is respectively connected to an outlet conduit 8 for discharging at least a part of the flue gas or a flue gas mixture, while the respective port F with a Fresh air line 9 for the intake of fresh air is in communication.

Die erfindungsgemäße Vorrichtung arbeitet in folgender Weise:The device according to the invention operates in the following way:

Zum Abrauchen der sich in der Rauchposition 2 befindlichen Zigarette wird ein Drehschieber S eines als Drehschieberventil ausgebildeten 5/4-Wege-Ventil 5-1, 5-2, 5-3, 5-4 jeweils mittels z.B. eines Schrittmotors so gesteuert, dass ein Ventilweg zwischen den Anschlüssen S und P besteht, so dass die Zigarette durch die Hubvergrößerung der Kolbenpumpe 4-1, 4-2, 4-3, 4-4 geraucht und deren Rauchgas angesaugt wird. Danach wird das Ventil so gesteuert, dass ein Ventilweg P-E, also ein Ventilweg zwischen der Pumpe 4-1, 4-2, 4-3, 4-4 und der Auslass-Leitung 8 geschaffen wird, über den bei einer Verkleinerung des Pumpenvolumens das angesaugte Rauchgas teilweise ausgeblasen wird, so dass nur noch ein Teilvolumen des ursprünglich angesaugten Rauchgases im Pumpenzylinder verbleibt.In order to fume off the cigarette located in the smoke position 2, a rotary valve S of a 5/4-way valve 5-1, 5-2, 5-3, 5-4 designed as a rotary slide valve is in each case connected by means of e.g. a stepping motor is controlled so that a valve path between the terminals S and P, so that the cigarette is smoked by the stroke magnification of the piston pump 4-1, 4-2, 4-3, 4-4 and the flue gas is sucked. Thereafter, the valve is controlled so that a valve path PE, that is, a valve path between the pump 4-1, 4-2, 4-3, 4-4 and the outlet line 8 is created over the case of a reduction of the pump volume aspirated flue gas is partially blown out, so that only a partial volume of the originally aspirated flue gas remains in the pump cylinder.

Als nächster Schritt wird durch Steuern des Ventils ein Ventilweg zwischen den Anschlüssen F und P geschaffen, so dass Frischluft in die Pumpe gelangt, die währenddessen so gesteuert wird, dass das Hubvolumen vergrößert und damit die im Kolben verbliebene Rauchgas bzw. das Rauchgas-Gemisch durch die Frischluft verdünnt wird.As a next step, by controlling the valve a valve path between the ports F and P is created so that fresh air enters the pump, which is meanwhile controlled so that the stroke volume increases and thus the remaining flue gas in the flask or the flue gas mixture the fresh air is diluted.

Ist durch diesen Vorgang die gewünschte Rauchgas-Verdünnung erreicht, wird durch Steuerung des Drehschiebers der Ventilweg P-C, also eine Verbindung zwischen der Pumpe 4-1, 4-2, 4-3, 4-4 und der Kammer 7-1, 7-2, 7-3, 7-4 geschaffen, so dass das die gewünschte Verdünnung aufweisende Rauchgas-Gemisch in die Kammer 7-1, 7-2, 7-3, 7-4 ausgeblasen wird.If the desired flue gas dilution is achieved by this process, by controlling the rotary valve, the valve path PC, ie a connection between the pump 4-1, 4-2, 4-3, 4-4 and the chamber 7-1, 7 2, 7-3, 7-4, so that the desired dilution flue gas mixture is blown into the chamber 7-1, 7-2, 7-3, 7-4.

Ist das Rauchgas dagegen zu diesem Zeitpunkt noch nicht ausreichend verdünnt, erfolgt ein weiterer Verdünnungszyklus, bei dem das Ventil 5-1, 5-2, 5-3, 5-4 zur Freigabe des Ventilweges P-E entsprechend angesteuert wird, so dass das in einem ersten Schritts bereits verdünnte Rauchgas-Gemisch über die Auslass-Leitung 8 teilweise ausgeblasen wird. Durch erneutes Öffnen des Ventilweges F-P gelangt wiederum Frischluft aus der Frischluftleitung 9 in die Pumpe 4-1, 4-2, 4-3, 4-4, deren Zylindervolumen durch Zurückziehen des Pumpenkolbens vergrößert wird, so dass das Luftgemisch weiter verdünnt wird. Ist auch nach dem zweiten Verdünnungszyklus die gewünschte Verdünnung des Rauchgases noch nicht erreicht, werden entsprechend weitere Verdünnungszyklen in der beschriebenen Weise durchgeführt, bis nach Erreichen der gewünschten Verdünnung das Rauchgas dann über den Ventilweg P-C in die Kammer 7-1, 7-2, 7-3, 7-4 ausgeblasen wird.On the other hand, if the flue gas is not yet sufficiently diluted at this point in time, another dilution cycle takes place, in which the valve 5-1, 5-2, 5-3, 5-4 is correspondingly activated to release the valve path PE, so that in one first step already dilute flue gas mixture through the outlet pipe 8 partially blown out. By reopening the valve path FP again fresh air from the fresh air line 9 passes into the pump 4-1, 4-2, 4-3, 4-4, the cylinder volume is increased by retracting the pump piston, so that the air mixture is further diluted. If the desired dilution of the flue gas has not yet been reached after the second dilution cycle, further dilution cycles are accordingly carried out in the manner described until, after reaching the desired dilution, the flue gas then flows via the valve path PC into the chamber 7-1, 7-2, 7 -3, 7-4 is blown out.

Mit der erfindungsgemäßen Vorrichtung ist es gemäß dieser Vorgehensweise möglich, eine Zigarette, die sich an der Rauchposition 2 befindet, gleichzeitig mit mehreren Rauchgasmischeinheiten abzurauchen und dasselbe Rauchgas unterschiedlich zu verdünnen und auf unterschiedliche Weise zu untersuchen.With the device according to the invention, it is possible according to this approach to simultaneously scrape off a cigarette which is located at the smoke position 2 with a plurality of flue gas mixing units and to dilute the same flue gas differently and to examine it in different ways.

Die erfindungsgemäße Vorrichtung ist jedoch auch im besonderen Maße dafür geeignet, jeweils nur eine Rauchgas-Mischeinheit, die aus einer Pumpe 4-n, einem Ventil 5-n, einer Kammer 7-n sowie einem Schlauch oder Kanal 3-n zwischen Rauchposition 2 und Ventil 5-n sowie einer Leitung 6-n zwischen dem jeweiligen Anschluss C des Ventils 5-n und der Kammer 7-n besteht, zu berauchen, und eine andere Rauchgas-Mischeinheit für eine Zigarette zu aktivieren, wenn sich eine der nächsten Zigaretten an der Rauchposition 2 befindet. Auf diese Weise ist es möglich, mit derselben Vorrichtung die Zigaretten in unterschiedlicher Weise abzurauchen und/oder unterschiedliche Zigaretten abzurauchen, wenn in den einzelnen Zigarettenhaltern 1-n unterschiedliche Sorten von Zigaretten angeordnet sind. Dies bedeutet, dass die Vorrichtung dazu geeignet ist, im selben Zyklus unterschiedliche Sorten von Zigaretten abzurauchen und das Rauchgas der unterschiedlichen Zigaretten auch getrennt voneinander und im wesentlichen gleichzeitig in der gewünschten Weise und individuell zu verdünnen und für die Rauchgas-Untersuchungen bereitzustellen.However, the device according to the invention is also particularly suitable for, in each case only a flue gas mixing unit consisting of a pump 4-n, a valve 5-n, a chamber 7-n and a hose or channel 3-n between smoke position 2 and Valve 5-n and a line 6-n between the respective port C of the valve 5-n and the chamber 7-n is to exhale and to activate another flue gas mixing unit for a cigarette when one of the next cigarettes the smoke position 2 is located. In this way it is possible with the same device to scrape off the cigarettes in different ways and / or to scrape off different cigarettes if different types of cigarettes are arranged in the individual cigarette holders 1-n. This means that the device is capable of scavenging different types of cigarettes in the same cycle and of separately diluting the flue gas of the different cigarettes separately and substantially simultaneously in the desired manner and individually and for the flue gas examinations.

Die vorliegende Erfindung wurde zuvor anhand eines bevorzugten Ausführungsbeispiels beschrieben. Dem Fachmann sind jedoch Ausgestaltungen, Abwandlungen und Modifikationen möglich, und ohne dass dadurch der Erfindungsgedanke verlassen wird. Beispielsweise ist es möglich, mehr oder weniger als vier Rauchgas-Mischeinheiten und/oder vier Zigarettenhalter vorzusehen. Auch kann jede Rauchgas-Mischeinheit jeweils mit ihren Rauchgaskanälen 3-1, 3-2, 3-3, 3-4 mit unterschiedlichen Positionen des Rauchkarussells verbunden werden, so dass gleichzeitig mehrere Zigaretten der gleichen oder unterschiedlichen Sorte geraucht und deren Rauchgase verdünnt werden können.The present invention has been described above with reference to a preferred embodiment. However, embodiments, modifications and modifications are possible for the person skilled in the art, without the Inventive concept is left. For example, it is possible to provide more or fewer than four flue gas mixing units and / or four cigarette holders. Also, each flue gas mixing unit can each be connected to their flue gas ducts 3-1, 3-2, 3-3, 3-4 with different positions of the smoking carousel, so that simultaneously smoked several cigarettes of the same or different variety and their flue gases can be diluted ,
