Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft allgemein eine Vorrichtung zur optimierten rauchfreien Inhalation von Nikotin und/oder Zusatzstoffen mit elektronischen Zigaretten.The present invention generally relates to a device for optimized smoke-free inhalation of nicotine and / or additives with electronic cigarettes.

Allgemeine EinleitungGeneral introduction

Beim Rauchen einer herkömmlichen Zigarette wird Tabak verbrannt und der bei dieser Verbrennung entstehende Rauch wird inhaliert (Hauptstromrauch) oder an die Umgebung abgegeben (Nebenstromrauch).When smoking a conventional cigarette tobacco is burned and the resulting smoke from this smoke is inhaled (mainstream smoke) or released to the environment (sidestream smoke).

Der Hauptstromrauch ist maßgeblich für die Gesundheitsschädigung des Konsumenten verantwortlich, liefert ihm aber den gewünschten Genuss. Der Nebenstromrauch ist maßgeblich für die Gesundheitsschädigung der Passivraucher verantwortlich und ist weder von den Passivrauchern noch vom Konsumenten gewünscht.The mainstream smoke is largely responsible for the health of the consumer, but provides him with the desired enjoyment. The sidestream smoke is largely responsible for the health damage of passive smokers and is desired by neither the passive smokers nor the consumer.

Im Rauch einer Zigarette wurden über 4800 verschiedene Substanzen nachgewiesen von denen ungefähr 70 als nachweislich krebserregend gelten.In the smoke of a cigarette more than 4,800 different substances have been detected, of which about 70 are considered to be carcinogenic.

Verfahren und darauf basierende Vorrichtungen zur rauchfreien Inhalation von Nikotin und/oder Zusatzstoffen haben zum Ziel dem Konsumenten ein Substitut zur herkömmlichen Zigarette zu bieten, welches eine wesentlich geringere Gesundheitsschädigung beim Konsumenten und Dritten, vorzugsweise gar keine Gesundheitsschädigung beim Konsumenten und Dritten verursacht, dabei jedoch das Konsumerlebnis einer herkömmlichen Zigarette beibehält.Methods and devices based thereon for the smoke-free inhalation of nicotine and / or additives have the goal of offering the consumer a substitute for the conventional cigarette, which causes a much lower damage to the health of the consumer and third parties, preferably no damage to health of the consumer and third parties, but this Retains the consumer experience of a conventional cigarette.

Stand der TechnikState of the art

Aktuell etablieren sich als Ersatz zur herkömmlichen Zigarette sogenannte E-Cigarettes (elektronische Zigaretten) am Markt. Von verschiedenen Ansätzen hat sich der im Folgenden beschriebene Ansatz, aufgrund seiner verhältnismäßig einfachen technischen Umsetzbarkeit bei gleichzeitig überzeugender Funktionalität (Verdampferleistung, Nikotinoutput durchgesetzt.Currently established as a replacement for conventional cigarette so-called e-cigarettes (electronic cigarettes) on the market. Of different approaches, the approach described below, due to its relative simple technical feasibility with simultaneously convincing functionality (evaporator performance, nicotine output prevailed.

Das Patent DE69017371T2 aus dem Jahre 1990 beschreibt eine Raucherware, welche ein aromastofferzeugendes Medium, ein elektrisches Heizelement und eine elektrische Energieabgabeeinrichtung aufweist, wobei das aromastofferzeugende Medium von dem elektrischen Heizelement lösbar ist, dadurch gekennzeichnet, dass das elektrische Heizelement im Wärmekontakt mit dem aromastofferzeugenden Medium ist, dass die elektrische Energieabgabeeinrichtung elektrische Energie an das Heizelement abgibt, um zu bewirken, dass das Heizelement das aromastofferzeugende Medium erwärmt und Aromastoffkomponenten hiervon freigesetzt werden, und dass eine Regeleinrichtung zur Regulierung der Menge der elektrischen Energieabgabe durch die Energieabgabeeinrichtung aufweist.The patent DE69017371T2 1990 describes a smoking article comprising a flavor generating medium, an electric heating element and an electrical energy dispensing device, wherein the flavor generating medium is detachable from the electric heating element, characterized in that the electrical heating element is in thermal contact with the flavor generating medium electrical energy dispensing device delivers electrical energy to the heating element to cause the heating element to heat the flavor-generating medium and release flavoring components therefrom, and that comprises a controller for regulating the amount of electrical energy output by the energy dispensing device.

Dieses Grundprinzip wurde im Laufe der letzten zwei Jahrzehnte zur Marktreife entwickelt und wie folgt optimiert.This basic principle has been developed to market readiness over the last two decades and optimized as follows.

Eine zu verdampfende Flüssigkeit wird durch die Kapillarwirkung eines Metallgeflechts oder Glasfaserdochtes aus einem Depot einer kleinen Heizspirale zugeführt. Diese wird in der Regel durch einen Unterdruckschalter bzw. Unterdruckregler beim Ziehen an der elektronischen Zigarette eingeschaltet, wodurch die Flüssigkeit (Liquid) verdampft.A liquid to be evaporated is supplied by the capillary action of a metal mesh or Glasfaserdochtes from a depot of a small heating coil. This is usually turned on by a vacuum switch or vacuum regulator when pulling on the electronic cigarette, whereby the liquid (liquid) evaporates.

Die Hauptkomponenten der elektronischen Zigarette sind: die Akkumulatoreinheit mit Unterdruckschalter bzw. Unterdruckregler und LED zur optischen Simulation der Glut, die Verdampfereinheit (Atomizer) mit Heizwendel und Kapillaren sowie das Mundstück mit dem Flüssigkeitsdepot.The main components of the electronic cigarette are: the accumulator unit with vacuum switch or vacuum regulator and LED for optical simulation of the embers, the evaporator unit (atomizer) with heating coil and capillaries and the mouthpiece with the liquid depot.

Die drei Komponenten sind in der Regel zylindrisch und imitieren in ihrer Form zusammengebaut eine Zigarette, wobei sie in ihrem Inneren einen Strömungskanal bilden, der sich durch alle drei Komponenten erstreckt. Beim Ziehen an der elektronischen Zigarette wird ein Luftstrom in die Akkumulatoreinheit eingesogen, wodurch der Unterdruckschalter bzw. Unterdruckregler betätigt wird. Dadurch wird die Heizwendel in der stromabwärts angeordneten Verdampfereinheit aktiviert.The three components are generally cylindrical and mimic a cigarette in their shape, forming a flow channel in their interior that extends through all three components. When pulling on the electronic cigarette, an air flow is sucked into the accumulator unit, whereby the vacuum switch or vacuum regulator is actuated. This activates the heating coil in the downstream evaporator unit.

Die helixförmige Heizwendel ist um ein Faserbündel gewickelt, welches direkt oder über ein Metallgeflecht mit einem weiter stromabwärts im Mundstück gelegenen Flüssigkeitsdepot durch Kapillare verbunden mit Flüssigkeit getränkt wird und orthogonal zur Strömung angeordnet ist. Durch das Aktivieren der Heizwendel wird Flüssigkeit verdampft und an den Luftstrom abgegeben.The helical heating coil is wound around a fiber bundle, which is impregnated directly or via a metal mesh with a liquid depot located further downstream in the mouthpiece through capillaries connected to liquid and arranged orthogonal to the flow. Activating the heating coil vaporizes liquid and releases it to the airflow.

Das mit der zu verdampfenden Flüssigkeit befüllte Depot selbst ist nicht direkt der Strömung im Strömungskanal ausgesetzt, sondern in einer Seitentasche des Mundstücks angeordnet. So wird das Faserbündel durch die Kapillare von Metallgeflecht und Glasfaserbündel versorgt, ohne dass zwangsläufig unverdampfte Flüssigkeit aus dem Depot in den Mund des Konsumenten gelangt. Das Depot besteht meist aus einem kleinen Stück Vlies.The filled with the liquid to be evaporated depot itself is not directly exposed to the flow in the flow channel, but arranged in a side pocket of the mouthpiece. Thus, the fiber bundle is supplied by the capillary of metal mesh and glass fiber bundles, without inevitably unvaporized liquid from the depot into the mouth of the consumer passes. The depot usually consists of a small piece of fleece.

Neben dem Depot beinhaltet das Mundstück nur einen Strömungskanal und den Luftaustritt in Form einer kleinen Bohrung an seiner Stirnseite, durch den der mit verdampfter Flüssigkeit angereicherte Luftstrom in die Mundhöhle des Konsumenten gelangt.In addition to the depot, the mouthpiece contains only a flow channel and the air outlet in the form of a small hole at its end, through which the air flow enriched with vaporized liquid enters the oral cavity of the consumer.

Akkumulator- und Verdampfereinheit werden über ein Gewinde lösbar miteinander verbunden. Gewindestirnseite und Gewindefläche sind elektrisch leitend und voneinander isoliert, sodass im zusammengeschraubten Zustand ein elektrischer Strom zwischen Akkumulator- und Verdampfereinheit fließen und die Heizwendel bei aktiviertem Unterdruckschalter bzw. Unterdruckregler durch den Akku versorgt werden kann. Im demontierten Zustand kann die Akkumulatoreinheit über dasselbe Gewinde mit einem Ladegerät verbunden werden.Accumulator and evaporator unit are detachably connected to one another via a thread. Threaded face and threaded surface are electrically conductive and isolated from each other, so that in the bolted state, an electric current flow between the accumulator and evaporator unit and the heating coil can be powered by the battery with activated vacuum switch or vacuum regulator. In the disassembled state, the accumulator unit can be connected via the same thread with a charger.

Das Mundstück wird über einen zylindrischen Flansch auf das dem Gewinde gegenüberliegende Ende der Verdampfereinheit aufgesteckt wobei das Depot im Mundstück mit dem Metallgeflecht der Verdampfereinheit in Berührung kommt und der Flüssigkeitstransport aus dem Depot in das Innere der Heizspirale inganggesetzt wird.The mouthpiece is attached via a cylindrical flange on the thread opposite the end of the evaporator unit wherein the depot comes into contact with the metal mesh of the evaporator unit in the mouthpiece and the liquid transport from the depot is started in the interior of the heating coil.

Ein großer Nachteil dieser Ausgestaltung elektronischer Zigaretten mit separater wiederverwendbarer Verdampfereinheit ist die zunehmende Verschmutzung der Verdampfereinheit während ihrer Lebensdauer. Da vor dem Austausch der Verdampfereinheit in der Regel viele Depots à 200 Puffs konsumiert werden und die Kapillare nicht gereinigt werden besteht die potentielle Gefahr Mikroorganismen und unerwünschte schädliche Substanzen zu verdampfen. Bis zu 6 Monate kann eine Verdampfereinheit benutzt werden.A major disadvantage of this embodiment of electronic cigarettes with a separate reusable evaporator unit is the increasing contamination of the evaporator unit during its lifetime. Since many depots of 200 puffs are usually consumed before the replacement of the evaporator unit and the capillaries are not cleaned, there is the potential danger Microorganisms and undesirable harmful substances evaporate. Up to 6 months, an evaporator unit can be used.

Ein weiterer Nachteil der zunehmenden Verunreinigung der Verdampfereinheit ist die potentielle Qualitätseinbusse über die Konsumdauer. So vermischt sich z. B. beim Austausch eines Mundstücks die zu verdampfende Flüssigkeit des neuen Mundstücks mit der restlichen in den Kapillaren befindlichen Flüssigkeit. Besonders nachteilig ist dies, wenn der Konsument mit einem Verdampfer verschiedene Aromen konsumieren möchte.Another disadvantage of the increasing contamination of the evaporator unit is the potential loss of quality over the duration of consumption. So mixes z. B. when replacing a mouthpiece to be evaporated liquid of the new mouthpiece with the remaining liquid in the capillaries. This is particularly disadvantageous if the consumer wants to consume different flavors with an evaporator.

Ebenfalls nachteilig macht sich der Austritt von Flüssigkeit beim Wechseln der auf den Verdampfer aufgesteckten Mundstücke bemerkbar, wodurch der Konsument häufig in Hautkontakt mit nikotinhaltiger Flüssigkeit kommt. Je nach Nikotingehalt kann es durch den Hautkontakt zu leichten Vergiftungen kommen.Another disadvantage is the leakage of liquid when changing the plugged onto the evaporator mouthpieces noticeable, causing the consumer often comes into skin contact with nicotine-containing liquid. Depending on the nicotine content, skin contact may cause mild poisoning.

Nicht zuletzt ergibt sich aus dieser dreiteiligen Ausgestaltung eine schwer weiter zu reduzierende Länge als Nachteil, was der Zielsetzung den Bauraum einer King-Size Zigarette nicht merklich zu überschreiten zuwider läuft.Not least results from this three-part design a difficult to further reduce length as a disadvantage, which runs counter to the objective of the installation space of a king-size cigarette not appreciably.

Eine teilweise Verbesserung wird gegenüber den zuvor erwähnten Nachteilen erzielt, wenn die Verdampfereinheit in das Mundstück integriert wird, da der Austritt von Flüssigkeit und das damit verbundene Hautkontaktrisiko vermieden werden und der Bauraum besser einer King-Size Zigarette angenähert werden kann.A partial improvement is achieved over the aforementioned disadvantages when the evaporator unit is integrated into the mouthpiece, since the leakage of liquid and the associated skin contact risk can be avoided and the space can be better approximated to a King-size cigarette.

Als Nachteil stellt sich nun jedoch die mit dem Verdampfer in das Mundstück gewanderte Schraubverbindung dar, wodurch sich, abgesehen von der unkomfortablen Handhabung einer Schraubverbindung, aufgrund der relativ dicken metallischen Wandung im Bereich des Gewindes und dem nun gegebenen Einwegcharakter des kombinierten Produktes ein Entsorgungsproblem ergibt, besonders da es sich um ein Produkt für die Massenherstellung handelt wodurch sich der übermäßige Materialeinsatz potenziert.However, the disadvantage now is the wandered with the evaporator in the mouthpiece threaded connection, which, apart from the uncomfortable handling of a screw, due to the relatively thick metallic wall in the thread and the now given disposable character of the combined product results in a disposal problem, especially as it is a product for mass production which increases the use of materials.

Für beide zuvor genannten Varianten, d. h. sowohl für die Variante mit separatem Verdampfer, als auch für die Variante mit im Mundstück integriertem Verdampfer stellt die Nachfüllbarkeit der jeweiligen Depots sowie die damit verbundene bereits weit verbreitete Nachfüllpraxis aufgrund der potentiellen Gefahr, die von nikotinhaltigen Flüssigkeiten ausgehen, ein großes Problem dar. Nachfüllflaschen können eine für Kinder letale Dosis Nikotin enthalten.For both of the aforementioned variants, ie both for the variant with a separate evaporator, as well as for the variant with integrated evaporator in the mouthpiece, the refillability of the respective depots and the associated already widespread refilling practice due to the potential risk, the nicotine-containing liquids pose a major problem. Refill bottles may contain a lethal dose of nicotine for children.

Weiterhin wird der vermeintliche hygienische Vorteil der Systeme mit im Mundstück integriertem Verdampfer zunichte gemacht, da auch diese in der Praxis häufig nachgefüllt werden, obwohl diese anstelle der Glasfaserkapillare häufig Fasern als Kapillare verwenden, die bei längerem Gebrauch verkohlen.Furthermore, the perceived hygienic advantage of the systems with evaporator integrated in the mouthpiece is negated, since these too are frequently refilled in practice, although these often use fibers as capillaries instead of the glass fiber capillaries, which carbonize with prolonged use.

Abschließend liegt ein großer Nachteil der Systeme mit im Mundstück integriertem Verdampfer aufgrund der verwendeten Komponenten, wie dem spanend hergestellten Schraubflansch mit elektrischer Trennung von Außenring und Stirnseite, und des schwer automatisierbaren Zusammenbaus, wie der über Drähte mit dem Schraubflansch verlöteten Heizwendel und dem durch die Heizwendel geführten Glas- oder Naturfaserbündel, in der für ein Massenprodukt nicht gegebenen Herstellbarkeit auf schnell-laufenden Maschinen.Finally, a major disadvantage of the systems with integrated in the mouthpiece evaporator due to the components used, such as the machined Schraubflansch with electrical isolation of outer ring and end face, and the difficult automatable assembly, such as the soldered to the screw with the screw and the heating coil through the heating coil guided glass or natural fiber bundles, in the mass production not given manufacturability on high-speed machines.

WO2011/009920 beschreibt ein Verfahren zum Verflüchtigen von Wirk- und/oder Aromastoffen zwecks Abgabe eines inhalierbaren Aerosols, wobei ein mit Wärmeenergie beaufschlagtes Fluid einen Strömungskanal in einem vorzugsweise zylindrischen Hohlkörper durchströmt und wobei das Fluid in diesem Strömungskanal mindestens eine Verdampfermembran teilweise oder vollständig durchströmt, wobei die mindestens eine Verdampfermembran mit einer zu verdampfenden Wirk- und oder Aromastoff enthaltenden Substanz benetzt ist und/oder benetzt wird und wobei das zusätzlich Wärmeenergie beinhaltende, d.h. mit Wärmeenergie beaufschlagte Fluid beim Durchströmen der Verdampfermembran diese Substanz oder Substanzen verdampft und dem Fluidstrom zuführt. WO2011 / 009920 describes a method for volatilizing active substances and / or flavorings for the purpose of delivering an inhalable aerosol, wherein a heat-energized fluid flows through a flow channel in a preferably cylindrical hollow body and the fluid in this flow channel at least partially or completely flows through at least one evaporator membrane, wherein the at least an evaporator membrane is wetted with a substance to be evaporated containing active substance and / or flavoring and / or wetted and wherein the additional thermal energy-containing, ie acted upon with thermal energy fluid as it flows through the evaporator membrane vaporizes this substance or substances and supplies the fluid flow.

Das zuletzt genannte Verfahren sowie die darauf basierende Vorrichtung ermöglichen eine optimale Verdampfung von Wirk- und/oder Aromastoffe enthaltenden Substanzen ohne die zuvor genannten Nachteile, wie Hygieneprobleme, bauartbedingte hohe Herstellkosten und zu lange Konsumdauer, der am Markt erhältlichen elektrischen Systeme, wodurch es sich prinzipiell ideal als Mundstück für eine rauchfreie Zigarette eignet. Jedoch arbeitet das Verfahren mit einem durch Verbrennung von Flüssiggas bereits wärmebeaufschlagten Fluidstrom, wie er durch das in WO2008/113420 beschriebene Verfahren zur Verfügung gestellt wird, wogegen die rein elektrische Erzeugung eines entsprechend warmen Fluidstromes im Bauraum einer Zigarette oder kleinen Zigarre aufgrund unzureichendem Platz für einen Wärmetauscher nicht darstellbar ist.The latter method and the device based thereon allow optimal evaporation of substances containing active substances and / or flavorings without the aforementioned disadvantages, such as hygiene problems, design-related high production costs and excessively long consumption time of the electrical systems available on the market, which means in principle Ideal as a mouthpiece for a smoke-free cigarette. However, the process operates with a fluid stream already heat-treated by the combustion of liquefied gas, as represented by the in-flow WO2008 / 113420 described method is provided, whereas the purely electrical production of a correspondingly warm Fluid flow in the space of a cigarette or small cigar due to insufficient space for a heat exchanger can not be displayed.

WO 2008/113420 beschreibt ein Verfahren zur Verflüchtigung von Wirk- und/oder Aromastoffen zwecks Abgabe eines inhalierbaren Aerosols, wobei Verbrennungsgase eines brennbaren Gases, welches vorzugsweise mit Luftüberschuss verbrannt wird, teilweise oder vollständig, gegebenenfalls vermischt mit Umgebungsluft, durch einen Wirk- und/oder Aromastoff-Depot geführt werden und wobei eine gewünschte Temperatur durch den Anteil an Verbrennungsgasen und ggf. durch das Mischungsverhältnis dieser Verbrennungsgase mit Umgebungsluft wählbar ist. WO 2008/113420 describes a process for the volatilization of active substances and / or flavorings for the purpose of delivering an inhalable aerosol, wherein combustion gases of a combustible gas, which is preferably burned with excess air, partially or completely, optionally mixed with ambient air, by an active and / or flavor depot be guided and wherein a desired temperature by the proportion of combustion gases and optionally by the mixing ratio of these combustion gases with ambient air is selectable.

Ein entscheidender Nachteil dieses Verfahrens ist die Verwendung von Flüssiggas, wodurch aufgrund der vermeintlichen Explosionsgefahr in direkter Nähe zum Gesicht, auch wenn diese nur rein hypothetisch und durch Fail-Safe-Auslegung beherrschbar ist, nicht nur Sicherheitsbedenken bei potentiellen Kunden bestehen sondern darauf basierende Produkte mit hoher Wahrscheinlichkeit nicht an Bord von Flugzeugen mitgeführt werden dürfen.A major disadvantage of this method is the use of LPG, which due to the supposed danger of explosion in the immediate vicinity of the face, even if it is purely hypothetical and controllable by fail-safe design, not only safety concerns with potential customers but thereon based products high probability not to be carried on board aircraft.

Aufgabe der ErfindungObject of the invention

Eine Aufgabe der vorliegenden Erfindung ist es demnach eine Vorrichtung für elektronische Zigaretten bereit zu stellen, die eine Verdampfung von Nikotin und/oder Zusatzstoffen ohne wiederverwendbare mit zu verdampfender Flüssigkeit in Kontakt stehende Bauteile gewährleistet und vorzugsweise gleichzeitig eine starke Reduktion der Kosten und Umweltbelastung durch Reduktion der verwendeten Materialmenge sowie Optimierung der Maschinengängigkeit zu erzielen.Accordingly, it is an object of the present invention to provide a device for electronic cigarettes which ensures vaporization of nicotine and / or additives without reusable components in contact with liquid to be evaporated, and preferably at the same time a strong reduction of costs and environmental impact by reduction of used to achieve the amount of material used and optimization of machinability.

Allgemeine Beschreibung der ErfindungGeneral description of the invention

Diese Aufgabe wird erfindungsgemäß gelöst durch eine Verdampfervorrichtung wie in Anspruch 1 beschrieben. Die Verdampfervorrichtung ermöglicht Verdampfen von Flüssigkeiten aus der permeablen Verdampfermembran (ähnlich wie sie in WO 2011/009920 beschrieben ist) und beinhaltet eine Heizvorrichtung, wobei die Heizvorrichtung folgendes umfassen kann:

  • → Eine permeable Heizwiderstandsfolie in Gestalt einer Doppelspirale oder Schlangenlinie mit zwei Enden und Abmessung des Querschnittes einer Zigarette oder kleinen Zigarre, wobei die Zwischenräume der Doppelspirale oder Schlangenlinie des Heizwiderstandes (1) offen (permeabel) und somit durchlässig für strömende Fluide sind.
  • → Mindestens zwei elektrische Kontakte (Kontaktlaschen), die auf ihrer einen Seite fest mit dem jeweils gegenüberliegenden Ende der Heizwiderstandsfolie verbunden sind und mit ihrer anderen Seite frei liegen, wodurch sie lösbar mit einer geregelten oder gesteuerten Spannungsquelle verbunden werden können, wobei die Heizwiderstandsfolie und die elektrischen Kontakte vorzugsweise aus einem Stück gefertigt sind.
This object is achieved by an evaporator device as described in claim 1. The evaporator device allows evaporation of liquids from the permeable evaporator membrane (similar to that in US Pat WO 2011/009920 described) and includes a heating device, wherein the heating device may comprise:
  • → A permeable heating foil in the form of a double spiral or serpentine with two ends and dimensions of the cross section of a cigarette or cigar, the spaces of the double spiral or serpentine line of the heating resistor (1) being open (permeable) and thus permeable to flowing fluids.
  • → At least two electrical contacts (contact tabs) fixedly connected on one side to the respective opposite end of the heating resistor foil and exposed on the other side, whereby they can be detachably connected to a regulated or controlled voltage source, the heating foil and the electrical contacts are preferably made of one piece.

Permeabel bedeutet im Sinne der Erfindung sowohl für die Heizwiderstandsfolie als auch für die Verdampfermembranen, dass diese in Richtung ihrer Flächennormalen gasdurchlässig sind.Permeable means for the purposes of the invention for both the Heizwiderstandsfolie and for the evaporator membranes that they are permeable to gas in the direction of their surface normal.

Erfindungsgemäß besteht eine permeable Heizwiderstandsfolie aus einer elektrisch leitenden Folie welche vorzugsweise in eine Doppelspiral- oder Schlangenlinienform oder eine Kombination aus Doppelspiral- und Schlangenlinienform gestanzt oder lasergeschnitten wird.According to the invention, a permeable heating resistor foil consists of an electrically conductive foil which is preferably punched or laser cut into a double spiral or serpentine shape or a combination of double spiral and serpentine shape.

Die erfindungsgemäße Heizwiderstandsfolie besteht aus einem elektrisch leitenden Material vorzugsweise aus einer Aluminium- oder Edelstahllegierung und besonders vorzugsweise aus lebensmittelechtem Reinaluminium, einer AIMn-Legierung oder rostfreiem Stahl, wie X5CrNi18-10.The Heizwiderstandsfolie invention consists of an electrically conductive material, preferably made of an aluminum or stainless steel alloy, and more preferably made of food grade pure aluminum, an AIMn alloy or stainless steel, such as X5CrNi18-10.

Die Wandstärke einer erfindungsgemäßen permeablen Heizwiderstandsfolie liegt zwischen 0,01 mm und 0,2 mm, vorzugsweise jedoch zwischen 0,02 mm und 0,08 mm.The wall thickness of a permeable heating resistance film according to the invention is between 0.01 mm and 0.2 mm, but preferably between 0.02 mm and 0.08 mm.

In Abhängigkeit von der elektrischen Leitfähigkeit der zu verdampfenden Flüssigkeit kann die Heizwiderstandsfolie mit einer hitzebeständigen und elektrisch isolierenden Kunststoffschicht, vorzugsweise einer Schicht aus Polyimid, Mikanit oder Silikon überzogen werden, wodurch bei zu geringem elektrischen Widerstand
der zu verdampfenden Flüssigkeit im Verhältnis zum Widerstand der Heizwiderstandsfolie ein Kurzschluss vermieden wird. Mikanit im Sinne der Erfindung bezeichnet generell einen Kunstglimmer, d. h. ein Verbundwerkstoff bestehend aus Glimmerbruchstücken (Schichtsilicatbruchstücken) und Kunstharz als Matrixsystem. Beispielprodukte sind: flexibel Mikanit FLM M & P (bestehend aus mindestens 92% Muscovite oder alternativ Phlogopite, imprägniert mit einem hochtemperaturbeständigen Siliconbinder), Flexibel Mikanit FLM 521 P, usw.
Depending on the electrical conductivity of the liquid to be evaporated, the heating resistor film can be coated with a heat-resistant and electrically insulating plastic layer, preferably a layer of polyimide, micanite or silicone, whereby at too low electrical resistance
the liquid to be evaporated in relation to the resistance of the Heizwiderstandsfolie a short circuit is avoided. Micanite in the sense of the invention generally refers to an artificial mica, ie a composite consisting of mica fragments (layered silicate fragments) and synthetic resin as a matrix system. Example products are: flexible Mikanit FLM M & P (consisting of at least 92% Muscovite or alternatively Phlogopite, impregnated with a high-temperature resistant silicone binder), flexible Mikanit FLM 521 P, etc.

Eine solche Heizvorrichtung kann z. B. als elektrischer Heizwiderstand in einer Verdampfervorrichtung zum Verdampfen von Wirk- und/oder Aromastoffe enthaltenden Substanzen, z. B. einem wegwerfbaren Einwegmundstück für eine elektronische Zigarette, verwendet werden. Durch einfaches Aufstecken auf eine Akkumulatoreinheit mit Unterdruckschalter bzw. Unterdruckregler ist die elektronische Zigarette einsatzbereit. Wird der Stromkreis durch den Unterdruckschalter bzw. Unterdruckregler geschlossen, erhitzt und verdampft die Heizwiderstandsfolie die Flüssigkeit aus der Verdampfermembran.Such a heater may, for. B. as an electrical heating resistor in an evaporator device for evaporating active and / or flavor substances containing substances, eg. As a disposable disposable mouthpiece for an electronic cigarette. By simply plugging it onto an accumulator unit with vacuum switch or vacuum regulator, the electronic cigarette is ready for use. When the circuit is closed by the vacuum switch or vacuum regulator, the heating resistor foil heats and vaporizes the liquid from the evaporator membrane.

Ein weiterer Aspekt betrifft demnach eine Verdampfervorrichtung zum Verdampfen von Wirk- und/oder Aromastoffe enthaltenden Substanzen, vorzugsweise ausgestaltet als Mundstück in Form eines Hohlzylinders mit einem Fluideingang und einem Fluidausgang. Die Verdampfervorrichtung umfasst eine wie hierin beschriebene Heizvorrichtung und mindestens eine Verdampfermembran welche mit dem Heizwiderstand in Flächenkontakt steht. Die Verdampfermembran ist ebenfalls durchlässig für strömende Fluide und ist entweder mit einer zu verdampfenden Wirk- und/oder Aromastoffe enthaltenden Substanz benetzt, oder kann damit benetzt werden. Der Heizwiderstand und die Verdampfermembran(en) sind bevorzugt orthogonal oder winklig zur Richtung der das Mundstück passierenden Fluide angeordnet.A further aspect accordingly relates to an evaporator device for evaporating substances containing active substances and / or aroma substances, preferably configured as a mouthpiece in the form of a hollow cylinder with a fluid inlet and a fluid outlet. The evaporator device comprises a heating device as described herein and at least one evaporator membrane in surface contact with the heating resistor. The evaporator membrane is also permeable to flowing fluids and is either wetted with a substance to be evaporated containing active substances and / or flavoring substances, or can be wetted with it. The heating resistor and the evaporator membrane (s) are preferably arranged orthogonal or at an angle to the direction of the fluids passing through the mouthpiece.

Durch die angegebene Ausführung der Verdampfervorrichtung wird aufgrund der erfindungsgemäßen größtmöglichen Kontaktfläche zwischen Heizwiderstandsfolie und Verdampfermembran bzw. Verdampfermembranen nicht nur ein sehr hoher Verdampferwirkungsgrad erzielt, sondern auch eine optimal gleichmäßige Verdampfung.Due to the specified embodiment of the evaporator device not only a very high evaporator efficiency is achieved due to the largest possible contact area between Heizwiderstandsfolie and evaporator membrane or evaporator membranes according to the invention, but also an optimally uniform evaporation.

Ein weiterer wesentlicher Vorteil der Erfindung ist, dass durch eine Änderung der geometrischen Gestalt der Heizwiderstandsfolie, wie z. B. durch eine Änderung der Anzahl der Spiralwindungen, der Breite der Windungen und/oder der Wandstärke der Folie bzw. des dünnen Bleches die Leistung des Heizwiderstandes optimal an verschiedene zu verdampfende Substanzen mit unterschiedlichen Inhaltsstoffen angepasst werden kann.Another significant advantage of the invention is that by changing the geometric shape of the Heizwiderstandsfolie such. B. by changing the number of spiral turns, the width of the turns and / or the wall thickness of the film or the thin sheet, the performance of the heating resistor can be optimally adapted to different substances to be vaporized with different ingredients.

Durch entsprechende Wahl des Materials sowie der geometrischen Parameter der Heizwiderstandsfolie kann der elektrische Widerstand der Heizwiderstandsfolie im Bereich von 1 - 10 Ω eingestellt werden, wodurch bei einer möglichen Nennspannung einer angeschlossenen Ackumulatoreinheit von 1,2 V (NiCd) - 3,7 V (Li-Ion) ein Spektrum von 0,1 - 13,7 Watt Heizleistung im Querschnitt eines Zigarettenmundstücks abgedeckt werden kann.By appropriate choice of the material and the geometric parameters of the Heizwiderstandsfolie the electrical resistance of the Heizwiderstandsfolie can be adjusted in the range of 1 - 10 Ω, whereby at a possible rated voltage of a connected Ackumulatoreinheit of 1.2 V (NiCd) - 3.7 V (Li -Ion) a spectrum of 0.1 - 13.7 watts heating power in the cross-section of a cigarette mouthpiece can be covered.

Ein weiterer wichtiger Vorteil der Erfindung ist, dass in die Kontur der Heizwiderstandsfolie durch eine lokale Verjüngung (Engstelle) eine Schmelzsicherung integriert werden kann, die bei aufgebrauchter Flüssigkeit, aufgrund der dann fehlenden Kühlung, thermisch zerstört wird und das Mundstück unbrauchbar macht, wodurch sich ein Einwegmundstück mit gezielter Konsumdauer von 5 - 20 Zügen je 20 - 50 ml, vorzugsweise aber 8 - 12 Zügen je 35 ml besonders einfach darstellen lässt.Another important advantage of the invention is that in the contour of the Heizwiderstandsfolie by a local taper (bottleneck) a fuse can be integrated, which is thermally destroyed in depleted liquid due to the then lack of cooling and makes the mouthpiece useless, resulting in a Disposable mouthpiece with a targeted consumption of 5 - 20 puffs per 20 - 50 ml, but preferably 8 - 12 puffs per 35 ml.

In einer weiteren Ausgestaltung umfasst die Verdampfervorrichtung weiterhin einen Flansch zur lösbaren Verbindung einer gesteuerten oder geregelten elektrischen Spannungsquelle mit den elektrischen Polen, wobei die Kontaktlaschen, die mit dem jeweils gegenüberliegenden Ende der Doppelspirale oder Schlangenlinie des Heizwiderstands verbunden sind, nicht unmittelbar, d. h. nur über den Heizwiderstand, miteinander in Kontakt stehen. Diese Kontaktlaschen können über den Flansch in Verbindung mit den elektrischen Polen einer gesteuerten oder geregelten elektrischen Spannungsquelle gebracht werden.In a further embodiment, the evaporator device further comprises a flange for releasably connecting a controlled or regulated electrical voltage source to the electrical poles, wherein the contact tabs connected to the respective opposite end of the double spiral or serpentine line of the heating resistor are not directly, i. H. only via the heating resistor, in contact with each other. These contact tabs can be brought via the flange in conjunction with the electrical poles of a controlled or regulated electrical voltage source.

Vorzugsweise verdeckt eine Isolierfolie die Kontaktlaschen zu einer Flanschfläche auf der Innenseite des Hohlzylinders des Mundstücks. Die Isolierfolie weist bevorzugt im Bereich der Flanschfläche mindestens zwei axial versetzte Kontaktöffnungen, wobei diese Kontaktöffnungen vorzugsweise derart ausgestaltet sind, dass sie axial in einer Ebene liegen und jeweils nur eine Kontaktlasche
freigeben. Die Pole einer gesteuerten oder geregelten elektrischen Spannungsquelle sind z. B. zwei axial versetzte Ringe und im verbundenen Zustand von Mundstück und Spannungsquelle steht jeweils ein Pol der Spannungsquelle über die Kontaktöffnungen mit den Kontaktlaschen und über die Kontaktlaschen mit jeweils einem Ende der Doppelspirale oder Schlangenlinie des Heizwiderstands in Verbindung.
Preferably, an insulating film covers the contact tabs to a flange on the inside of the hollow cylinder of the mouthpiece. The insulating film preferably has at least two axially offset contact openings in the region of the flange surface, wherein these contact openings are preferably designed such that they lie axially in one plane and in each case only one contact tab
release. The poles of a controlled or regulated electrical voltage source are z. B. two axially offset rings and in the connected state of mouthpiece and voltage source is in each case a pole of the voltage source via the contact openings with the contact tabs and the contact tabs with one end of the double spiral or serpentine line of the heating resistor in combination.

In einer weiteren Ausführung, weisen die Kontaktlaschen und/oder die Flanschfläche bevorzugt mindestens eine Passnut und/oder Passnase auf, wobei diese ein entsprechendes Gegenstück in Form mindestens einer Passnase und/oder Passnut an der gesteuerten oder geregelten elektrischen Spannungsquelle besitzen. Im verbundenen Zustand von Mundstück und Spannungsquelle steht jeweils ein Pol der Spannungsquelle mit den Kontaktlaschen und über die Kontaktlaschen mit jeweils einem Ende der Doppelspirale oder Schlangenlinie des Heizwiderstands in Verbindung.In a further embodiment, the contact tabs and / or the flange surface preferably have at least one fitting groove and / or fitting nose, wherein they have a corresponding counterpart in the form of at least one fitting nose and / or fitting groove on the controlled or regulated electrical voltage source. In the connected state of mouthpiece and voltage source is in each case a pole of the voltage source with the contact tabs and the contact tabs with one end of the double spiral or serpentine line of the heating resistor in combination.

In einer weiteren, bevorzugten Ausführung erstreckt sich mindestens eine spitz zulaufende und/oder scharfkantige Öffnerlasche aus einer metallische Folie oder einem dünnen Blech mit ihrer spitzen und/oder scharfkantigen Seite voraus vom Heizwiderstand axial in Richtung des Flanschs des Mundstücks und ist derart ausgebildet, dass sie beim Verbinden von Mundstück und Spannungsquelle eine zwischen Heizwiderstand und Flansch befindliche Verschlussfolie einer Speicherkapsel, die mit einer Wirk- und/oder Aromastoffe enthaltenden Substanz gefüllt ist, ansticht und/oder aufschneidet.In a further preferred embodiment, at least one pointed and / or sharp-edged Öffnerlasche of a metallic foil or a thin sheet extends with its sharp and / or sharp side ahead of the heating resistor axially in the direction of the flange of the mouthpiece and is designed such that they when connecting mouthpiece and voltage source located between the heating resistor and flange sealing film of a storage capsule, which is filled with a substance containing active and / or flavoring substances, pricks and / or cuts.

Demnach ermöglicht die Erfindung nicht nur die Herstellung einer Kombination aus Depot- und Verdampferfunktion in einem Einwegmundstück mit, gegenüber bekannten Vorrichtungen dieser Art, effizienterer Verdampfung sowie geringerem Ressourcenverbrauch, sondern bietet auch ein genau definiertes zeitlich begrenztes Konsumerlebnis.Thus, the invention not only enables the production of a combination of depot and evaporator function in a disposable mouthpiece with, over known devices of this type, more efficient evaporation and lower resource consumption, but also provides a well-defined time-limited consumer experience.

Aufgrund der bevorzugten Herstellung der beschriebenen Heizwiderstandsfolie durch Stanzen und Gesenkbiegen, lässt sich diese hervorragend in einen schnell-laufenden Produktionsprozess integrieren, worin ein weiterer wesentlicher Vorteil der vorliegenden Erfindung begründet liegt.Due to the preferred production of the described Heizwiderstandsfolie by punching and Gesenkbiegen, this can be excellently integrated into a fast-running production process, wherein a further significant advantage of the present invention is justified.
