Die Inhaltsstoffe der rauchfreien Zigarette sind vergleichsweise kostengünstig und die Benutzung der Zigarette ist vergleichsweise einfach, da die Wärmeeinheit autark ausgeführt ist, das heißt keine externe Wärmeeinheit, Stromversorgung oder sonstige Energiezufuhr erforderlich ist.The ingredients of the smokeless cigarette are relatively inexpensive and the use of the cigarette is relatively simple, since the heat unit is self-sufficient, that is no external heat unit, power supply or other energy supply is required.

Vorzugsweise ist vorgesehen, dass das Metall oder die Metallverbindung in Form eines Pulvers vorliegt. In diesem Fall ergibt sich eine besonders große Oberfläche, die eine besonders effektiv ablaufende Oxidation des Metalls bzw. der Metallverbindung, die auch als Legierung ausgeführt sein kann, ermöglicht.It is preferably provided that the metal or the metal compound is in the form of a powder. In this case, a particularly large surface results, which allows a particularly effective running oxidation of the metal or the metal compound, which may also be designed as an alloy.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Wärmeeinheit des Weiteren ein Aktivierungsmittel zur Initiierung und/oder zur Unterstützung der genannten Oxidationsreaktion aufweist. Das Aktivierungsmittel kann beispielsweise Aktivkohle umfassen.

Das luftdichte Verschließen der Wärmeeinheit vor Benutzung bewirkt, dass die die Wärme freisetzende Reaktion nicht bereits beginnt, bevor der Benutzer dies wünscht. Wird der Luftzutritt nach der Aktivierung der rauchfreien Zigarette durch den Nutzer ermöglicht, kann der Luftsauerstoff dazu herangezogen werden, das Metall bzw. die Metallverbindung zu oxidieren.Airtight sealing of the heating unit prior to use will cause the heat-releasing reaction not to commence before the user so desires. If the air access after the activation of the smoke-free cigarette by the user allows the atmospheric oxygen can be used to oxidize the metal or the metal compound.

Alternativ oder zusätzlich zu der Verwendung von Luftsauerstoff als Oxidationsmittel kann vorgesehen sein, dass die Wärmeeinheit selbst das Oxidationsmittel enthält. In diesem Falle ist nicht einmal der Zutritt von Luftsauerstoff erforderlich. Eine bevorzugte Ausgestaltung der Erfindung sieht jedoch vor, dass der Sauerstoff zur Oxidation des Metalls bzw. Metallpulvers durch Luftsauerstoff gebildet wird, der nach der Aktivierung der rauchfreien Zigarette durch den Benutzer in die Wärmeeinheit einströmen und dort die Oxidation des Metalls bzw. der Metallverbindung vornehmen kann.As an alternative or in addition to the use of atmospheric oxygen as the oxidizing agent, it can be provided that the heating unit itself contains the oxidizing agent.

Bei dem Substrat kann es sich beispielsweise um Tabak und vorzugsweise um mit Nikotin oder einer Nikotinverbindung angereicherten Tabak handeln.For example, the substrate may be tobacco, and preferably nicotine or nicotine compound enriched tobacco.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Nikotin-Reservoir derart angeordnet ist, dass es durch die Wärmeeinheit erwärmbar ist. In diesem Fall wird die Reaktionswärme der Oxidationsreaktion dazu genutzt, das Nikotin aus dem Nikotin-Reservoir freizusetzen bzw. in die Gasphase überzuführen. Sodann kann es mit dem von dem Nutzer initiierten Luftzug inhaliert werden.In a further embodiment of the invention, it is provided that the nicotine reservoir is arranged such that it can be heated by the heating unit.

Die Zigarette kann weiterhin einen Filter aufweisen, der in erster Linie die Aufgabe hat, eine Limitierung des von einem Nutzer erzeugten Luftvolumenstroms zu gewährleisten und/oder die in der Luft befindlichen Schadstoffe zurückzuhalten. In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Zigarette eine die Wärmeeinheit umgebende Ummantelung aufweist. Die Ummantelung kann beispielsweise aus beschichtetem Papier ausgeführt sein. Sie kann die Aufgabe haben, den direkten Kontakt des Nutzers mit der Wärmequelle bzw. der Wärmeeinheit zu verhindern. Vorzugsweise ist diese Ummantelung so ausgeführt, dass sie optisch einer herkömmlichen Zigarette gleicht.The cigarette may further comprise a filter which primarily has the task of ensuring a limitation of the air volume flow generated by a user and / or retaining the pollutants in the air.

Die Zigarette kann ein Verschlusselement, insbesondere eine Kappe oder dergleichen aufweisen. Vorzugsweise verschließt das Verschlusselement das Ende der Zigarette, das von dem bei Benutzung im Mund befindlichen Ende beabstandet ist. Denkbar ist es somit, dass das eine Ende der Zigarette durch das Mundstück bzw. durch den im Mund befindlichen Abschnitt der Zigarette gebildet wird und dass das andere Ende durch die Kappe verschlossen wird.The cigarette may have a closure element, in particular a cap or the like. Preferably, the closure member seals the end of the cigarette which is spaced from the end in use in the mouth. It is therefore conceivable that the one end of the cigarette is formed through the mouthpiece or through the mouth portion of the cigarette and that the other end is closed by the cap.

Das Verschlusselement kann derart ausgeführt sein, dass der Zutritt von Luft oder zumindest von Luftsauerstoff verhindert oder soweit reduziert wird, dass die Oxidationsreaktion nicht oder nicht in merklichem Umfang in Gang kommt, wenn sich das Verschlusselement noch an der Zigarette befindet. Durch Entfernen des Verschlusselementes kann der Nutzer die Oxidationsreaktion und somit die Wärmefreisetzung initiieren.The closure element may be designed such that the access of air or at least of atmospheric oxygen is prevented or reduced to such an extent that the oxidation reaction does not or does not commence appreciably when the closure element is still on the cigarette. By removing the closure element, the user can initiate the oxidation reaction and thus the heat release.

Die Ummantelung 12 umgibt gemäß dem in der Zeichnung dargestellten Ausführungsbeispiel nur die Wärmeeinheit 14, nicht jedoch das Mundstück 18. Grundsätzlich ist es denkbar, die Ummantelung 12 auch über die gesamte Länge der rauchfreien Zigarette und damit auch über das Mundstück 18 zu führen.The sheathing 12 surrounds according to the embodiment shown in the drawing, only the heat unit 14, but not the mouthpiece 18. In principle, it is conceivable to lead the sheath 12 over the entire length of the smoke-free cigarette and thus also via the mouthpiece 18.

Zieht der Nutzer Luft durch das Mundstück 18 wird der Luftstrom durch den Tabak 16 geführt und dabei aufgrund der durch die Wärmeeinheit 14 erzeugten Wärme über die Wirklänge erwärmt. Dies führt zu einer Erwärmung der Luft sowie einer Förderung der Freisetzung des Nikotins in den Luftstrom. Der Luftstrom nimmt das verdampfende Nikotin nebst Aromastoffen auf und wird über das Mundstück 18, das auch als Filter dienen kann, geleitet. Das Mundstück 18 begrenzt den Luftstrom und ist so dimensioniert, dass Nikotingrenzwerte nicht erreicht werden.If the user draws air through the mouthpiece 18, the air flow is guided through the tobacco 16 and thereby heated due to the heat generated by the heat unit 14 over the effective length. This leads to a warming of the air and a promotion of the release of nicotine in the air stream. The air stream absorbs the vaporizing nicotine along with flavorings and is delivered via the mouthpiece 18, which can also serve as a filter, passed. The mouthpiece 18 limits the flow of air and is dimensioned so that nicotine thresholds are not reached.

Die rauchfreie Zigarette 10 gemäß der vorliegenden Erfindung funktioniert ohne Wärme- oder Energiezufuhr von außerhalb und ist somit autark. Die rauchfreie Zigarette der vorliegenden Erfindung ist so gestaltet, dass sie sofort funktionsbereit ist, sofern der Nutzer dies wünscht.The smoke-free cigarette 10 according to the present invention works without heat or energy from outside and is thus self-sufficient. The smokeless cigarette of the present invention is designed so that it is immediately ready for use, if the user so desires.

In den Wärmeeinheiten befindet sich außer Eisenpulver, frische, feine Aktiv-Kohle, Kochsalz und Wasser.In the heat units is except iron powder, fresh, fine activated carbon, cooking salt and water.

Die Wärmeeinheit (Pad) 14 ist vor ihrer Aktivierung durch den Nutzer luftdicht verschlossen. Wird der Aktivierungsvorgang eingeleitet, ergibt sich an der Oberfläche der Wärmeeinheit 14 eine Temperatur von etwa 80°C. Die Menge an Reaktionsteilnehmern ist derart bemessen, dass die Wärme einige Minuten lang abgegeben wird bzw. sich einige Minuten lang hält.The heat unit (pad) 14 is hermetically sealed before being activated by the user. When the activation process is initiated, a temperature of about 80 ° C. results on the surface of the heating unit 14. The amount of reactants is such that the heat is released for a few minutes or lasts for a few minutes.

Die Reaktion des Eisens ist eine Oxidationsreaktion. In dem vorliegenden Beispiel erfolgt die Oxidation durch Luftsauerstoff, der dabei reduziert wird.The reaction of iron is an oxidation reaction. In the present example, the oxidation is carried out by atmospheric oxygen, which is thereby reduced.

Das Reaktionsschema basiert auf folgenden Reaktionen:

         Oxidation Fe → Fe3++ 3 e-

         Reduktion O + 2 e- → O2-

bzw.

         Oxidation 2 Fe → 2 Fe3++ 6 e-

         Reduktion 3 O + 6 e- → 3 O2-

The reaction scheme is based on the following reactions:

Oxidation Fe → Fe 3+ + 3 e -

Reduction O + 2 e - → O 2-

respectively.

Oxidation 2 Fe → 2 Fe 3+ + 6 e -

Reduction 3 O + 6 e - → 3 O 2-

Sauerstoff liegt als O2 vor, somit gilt:

         Oxidation 4 Fe → 4 Fe3++ 12 e-

         Reduktion 3 O2 + 12 e- → 6 O2-

bzw.

         Oxidation 4 Fe + 12 H2O → 4 Fe(OH)3 + 12 H+ + 12 e-

         Reduktion 3 O2 + 6 H2O + 12 e- → 12 OH-

Oxygen is present as O 2 , thus:

Oxidation 4 Fe → 4 Fe 3+ + 12 e -

Reducing 3 O 2 + 12 e - → O 6 2-

respectively.

Oxidation 4 Fe + 12 H 2 O → 4 Fe (OH) 3 + 12 H + + 12 e -

Reducing 3 O 2 + 6 H 2 O + 12 e - → OH 12 -

Daraus ergibt sich die Gesamtreaktionsgleichung herleiten (einschließlich der Reaktion H+ + OH- → H2O)

         4 Fe + 3 O2 + 6 H2O → 4 Fe(OH)3

This gives the general reaction equation (including the reaction H + + OH - → H 2 O)

4 Fe + 3 O 2 + 6 H 2 O → 4 Fe (OH) 3

Figur 2 zeigt ein Ausführungsbeispiel, das weitgehend dem zu Figur 1 erläuterten entspricht, so dass entsprechend Bezug genommen wird. FIG. 2 shows an embodiment that is largely to FIG. 1 explained, so that reference is made accordingly.

Als Unterschied zu dem Ausführungsbeispiel gemäß Figur 1 ist gemäß Figur 2 vorgesehen, dass das vom Mundstück 18 beabstandete Ende der Zigarette 10 durch eine Verkappung 20 geschlossen ist. Vor Anwendung trennt oder reißt der Nutzer die Kappe 20 von der Zigarette 10 ab, was zur Folge hat, dass Luftsauerstoff mit dem Eisen in Kontakt treten kann und die Oxidationsreaktion in Gang gesetzt wird. Das Entfernen der Kapp 20 hat ferner die Wirkung, dass überhaupt eine Luftströmung durch die Zigarette bzw. durch das Tabak-Substrat 16 erfolgen kann.As a difference from the embodiment according to FIG. 1 is according to FIG. 2 provided that the end of the cigarette 10 spaced from the mouthpiece 18 is closed by a capping 20. Before use, the user disconnects or tears off the cap 20 from the cigarette 10, with the result that atmospheric oxygen can contact the iron and the oxidation reaction is initiated. The removal of the cap 20 also has the effect that even an air flow through the cigarette or through the tobacco substrate 16 can take place.

Außer dem in der Figur 1 und 2 dargestellten Ausführungsbeispiel ist es auch denkbar, die Anordnung der Wärmeeinheit sowie des nikotinhaltigen Substrats zu verändern. Denkbar ist es beispielsweise, in Längsrichtung der Zigarette Wärmeeinheit und nikotinhaltiges Substrat hintereinander anzuordnen. Denkbar ist es beispielsweise, die Wärmeeinheit an dem vom Mundstück 18 beabstandeten Ende der Zigarette anzuordnen und zwischen Wärmeeinheit und Mundstück das nikotinhaltige Substrat anzuordnen.Except in the FIG. 1 and 2 illustrated embodiment, it is also conceivable to change the arrangement of the heat unit and the nicotine-containing substrate. It is conceivable, for example, in the longitudinal direction of the cigarette heat unit and nicotine-containing substrate to be arranged one behind the other. It is conceivable, for example, to arrange the heat unit at the end of the cigarette which is at a distance from the mouthpiece 18 and to arrange the nicotine-containing substrate between the heat unit and the mouthpiece.

Eine solche Ausgestaltung der Zigarette ist aus Figur 3 ersichtlich. Zwischen Wärmeeinheit 14 und Mundstück 18 befindet sich das nikotinhaltige Substrat 16. Auch in dem Ausführungsbeispiel gemäß Figur 3 ist die Wärmeeinheit 14 durch die Kappe 20 verschlossen, die den Zutritt von Sauerstoff zu der Wärmeeinheit 14 verhindert, bis sie vom Nutzer entfernt wird.Such a design of the cigarette is off FIG. 3 seen. Between heat unit 14 and mouthpiece 18 is the nicotine-containing substrate 16. Also in the embodiment according to FIG. 3 the heating unit 14 is closed by the cap 20, which prevents the access of oxygen to the heating unit 14 until it is removed by the user.

Aus Figur 3 ist es weiter ersichtlich, dass die Wärmeeinheit 14 von Luftkanälen 15 durchsetzt ist. Diese verlaufen in Längsrichtung der Zigarette 10. Das Merkmal, dass in der Wärmeeinheit 14 ein oder mehrere Luftkanäle 15 angeordnet sind, um die Luftzufuhr zu verbessern, ist nicht auf das Ausführungsbeispiel gemäß Figur 3 beschränkt, sondern ist eine grundsätzlich mögliche Ausgestaltung der vorliegenden Erfindung.Out FIG. 3 it is further apparent that the heating unit 14 is penetrated by air channels 15. These extend in the longitudinal direction of the cigarette 10. The feature that in the heating unit 14, one or more air ducts 15 are arranged to improve the air supply is not on the embodiment according to FIG. 3 limited, but is a fundamentally possible embodiment of the present invention.

Denkbar ist es, die Ummantelung der Zigarette luftdicht auszuführen. Denkbar ist es jedoch auf, die Ummantelung luftdurchlässig auszuführen, was zur Folge hat, dass Sauerstoff auch (oder ausschließlich) über die Mantelfläche in die Wärmeeinheit eindringt. Um zu verhindern, dass dies der Fall ist, bevor der Nutzer dies möchte, kann vorgesehen sein, die Ummantelung mit einer luftdichten Hülle zu versehen, die vom Nutzer abgezogen werden kann.It is conceivable to make the jacket of the cigarette airtight. However, it is conceivable to make the casing permeable to air, with the result that oxygen also (or exclusively) penetrates into the heating unit via the lateral surface. In order to prevent this from happening before the user wishes to do so, it may be provided to provide the sheath with an airtight sheath which can be removed by the user.

Die vorliegende Erfindung betrifft nicht nur Zigaretten im eigentlichen Sinne, sondern auch Zigarren. Der Begriff "Zigarette" steht somit sowohl für Zigaretten als auch für Zigarren.The present invention not only concerns cigarettes in the true sense, but also cigars. The term "cigarette" thus stands for both cigarettes and cigars.
