Description
Mundstückverschluss für ein Mundstück einer elektrischen Zigarette Mouthpiece closure for a mouthpiece of an electric cigarette
Die Erfindung betrifft einen Mundstückverschluss für ein Mundstück einer elektrischen Zigarette, die ein Gehäuse mit einem Verdampfer und einem mit dem Verdampfer verbundenem Depot für das Liquid zwischen Verdampfer und Mundstück umfasst, wobei der Verdampfer mit dem Mundstück für den Dampfaustritt verbunden ist. The invention relates to a mouthpiece closure for a mouthpiece of an electric cigarette, comprising a housing with an evaporator and a connected to the evaporator depot for the liquid between the evaporator and mouthpiece, wherein the evaporator is connected to the mouthpiece for the steam outlet.
Elektrische Zigaretten sind seit längerem bekannt. Im Prinzip bestehen diese elektronischen Zigaretten aus einem Verdampfer, auch Atomizer genannt, in dem eine nikotinhaltige oder nikotinfreie meist aromatisierte Flüssigkeit, Liquid genannt, in Dampf verwandelt wird. Dazu enthält der Verdampfer eine Heizwendel, die über eine Stromversorgung, meist ein Akku, mit Energie versorgt wird. Das Liquid wird in einem Depot vorgehalten. Weiterhin ist ein Mundstück zum Inhalieren vorgesehen und ein Schalter, der die Stromversorgung des Verdampfers regelt. Der Schalter kann entweder manuell oder über Unterdruck, der beim Inhalieren (Ziehen) entsteht, betätigt werden. Meist weisen die elektronischen Zigaretten eine langestreckte zylindrische Form auf, die derjenigen einer konventionellen Zigarette nach empfunden ist. Der Dampf, der im Verdampfer durch Aufheizen des Liquids entsteht, wird beim Inhalieren zu sich genommen. Electric cigarettes have been known for some time. In principle, these electronic cigarettes consist of an evaporator, also called an atomizer, in which a nicotine-containing or nicotine-free, usually flavored liquid, called liquid, is converted into steam. For this purpose, the evaporator contains a heating coil, which is powered by a power supply, usually a battery, with energy. The liquid is held in a custody account. Furthermore, a mouthpiece is provided for inhalation and a switch that regulates the power supply of the evaporator. The switch can be actuated either manually or via negative pressure that occurs during inhalation (pulling). Most electronic cigarettes have an elongated cylindrical shape that is similar to that of a conventional cigarette. The vapor produced in the evaporator by heating up the liquid is consumed during inhalation.
Zentraler Bestandteil der elektronischen Zigaretten ist der Verdampfer, der üblicherweise eine Heizwendel umfasst, die aus einem Draht mit elektrischem Widerstand besteht, der sich beim Durchfluss von Strom erhitzt. Zum Schutz der Heizwendel ist dies meist mit einem Drahtgeflecht oder Metallnetz bedeckt oder in einer weitestgehend abgeschlossenen Brennkammer enthalten, die lediglich kleine Eintrittsöffnungen für das Liquid aufweist. Das Liquid ist in dem Depot vorgehalten und wird von diesem nach und nach an den Verdampfer abgegeben. Das Depot besteht aus einer Hülle und ist meist mit einem Speicherstoff aus Watte, Glasfasern, Vlies etc. gefüllt, in dem das Liquid Central component of the electronic cigarettes is the evaporator, which usually comprises a heating coil, which consists of a wire with electrical resistance, which heats up as it flows. To protect the heating coil, this is usually covered with a wire mesh or metal mesh or contained in a largely completed combustion chamber, which has only small inlet openings for the liquid. The liquid is kept in the depot and is gradually released from it to the evaporator. The depot consists of a shell and is usually filled with a storage material made of cotton wool, fiberglass, fleece, etc., in which the liquid
schwammartig gespeichert ist. Ist der Atomizer zusammen mit dem Depot ausgestaltet, spricht man von einem Cartomizer (Cartridge + Atomizer). Aus der US 201 1/0303231 ist z.B. eine elektrische Zigarette bekannt, bei der der Verdampfer aus einem Glasfaser-Rohr, einem Garn aus Glasfasern, eine Heizspirale, ein Baumwolltuch Schicht und eine synthetische Faser Schicht besteht, wobei das Garn aus Glasfasern in die Heizspirale eingefügt ist, die sich innerhalb s Glasfaser- Rohrs befindet. Die Enden des Glasfasergarns und zwei Drähte, die verwendet werden, um die Heizspirale elektronisch mit den Anschlüsse zu verbinden, sind nach außen durch das Glasfaser Rohr geführt. is stored spongy. If the atomizer is configured together with the depot, it is called a cartomizer (cartridge + atomizer). From US 201 1/0303231, for example, an electric cigarette is known in which the evaporator consists of a glass fiber tube, a yarn of glass fibers, a heating coil, a cotton cloth layer and a synthetic fiber layer, wherein the yarn of glass fibers in the heating coil inserted inside the glass fiber tube. The ends of the fiberglass yarn and two wires used to electronically connect the heating coil to the terminals are led out through the glass fiber tube.
Die Baumwolltuch-Schicht umhüllt die Außenwand des Glasfaser-Rohrs und presst die Enden des Garns dicht gegen das Glasfaser-Rohr. Die synthetische Faser-Schicht zwischen dem Baumwolltuch Schicht und der Befestigungshülse speichert das Liquid und dient als eigentliches Depot. The cotton cloth layer envelops the outer wall of the glass fiber tube and presses the ends of the yarn tightly against the glass fiber tube. The synthetic fiber layer between the cotton cloth layer and the fastening sleeve stores the liquid and serves as the actual depot.
Aus der EP 2 404 515 A1 ist z.B. eine elektrische Zigarette bekannt, bei der die Hülle einen zusätzlichen Hilfs- Lufteinlass aufweist. Die elektrische Heizung weist eine Durchgangsbohrung auf und das mit Vlies etc. gefüllte Depot hat einen Kanal zwischen Mundstück und Verdampfer bzw. Durchgangsbohrung. Ein Unterdruck- Sensor ist mit der Durchgangsbohrung und dem Kanal verbunden und bildet einen Luftstrompfad mit dem Hilfslufteinlass aus, um aktiviert zu werden. Das im Vlies gespeicherte Liquid dringt durch eine zwischen Depot und Heizung angeordnete permeable Komponente und gelangt direkt auf die elektrische Heizung. From EP 2 404 515 A1 is known e.g. an electric cigarette is known in which the shell has an additional auxiliary air inlet. The electric heater has a through hole and filled with fleece, etc. Depot has a channel between mouthpiece and evaporator or through hole. A negative pressure sensor is connected to the through-hole and the channel and forms an air flow path with the auxiliary air inlet to be activated. The liquid stored in the fleece penetrates through a permeable component arranged between the depot and the heater and reaches the electric heater directly.
Daneben sind Tanksysteme bekannt, in denen das Liquid ohne Watte etc. im Depot gespeichert und über eine Membran etc. an den Verdampfer abgegeben wird. Dabei kommt meist eine hohle Nadel zum Einsatz, die die Membran durchstößt und mit dem Verdampfer kommuniziert. In addition, tank systems are known in which the liquid stored without cotton wool, etc. in the depot and discharged through a membrane, etc. to the evaporator. In most cases, a hollow needle is used, which pierces the membrane and communicates with the evaporator.
Problematisch an allen bekannten Systemen ist die gleichmäßige Zufuhr bzw. The problem with all known systems is the uniform supply or
Versorgung des Verdampfers mit Liquid, wobei gleichzeitig ein Auslaufen oder Ansaugen von nicht verdampftem Liquid verhindert werden muss, da z.B. das unverdampfte Nikotin extrem giftig ist. Daher ist wichtig, dass die Benutzer das unverdampfte Liquid nicht über das Mundstück ansaugen. Supply of the evaporator with liquid, at the same time a leakage or suction of non-evaporated liquid must be prevented, since e.g. the unvaporised nicotine is extremely toxic. Therefore, it is important that the users do not suck in the unvaporated liquid via the mouthpiece.
Dabei muss das Mundstück einerseits das Depot dicht verschließen und andererseits eine angenehme Haptik (und auch Optik) aufweisen. Aufgabe der Erfindung ist es daher, einen Mundstückverschluss für das Mundstück einer elektronischen Zigarette bereitzustellen, bei dem kein Auslaufen stattfindet und das gleichzeitig der Haptik Genüge tut. The mouthpiece must on the one hand close the depot tightly and on the other hand have a pleasant feel (and also optics). The object of the invention is therefore to provide a mouthpiece closure for the mouthpiece of an electronic cigarette, in which no leakage takes place and at the same time does the feel.
Diese Aufgabe wird durch den in Anspruch 1 wiedergegebenen Mundstückverschluss für ein Mundstück einer elektrischen Zigarette gelöst. This object is achieved by the recited in claim 1 mouthpiece closure for a mouthpiece of an electric cigarette.
Erfindungsgemäß ist erkannt worden, dass wenn der Mundstückverschluss ein dem Depot zugewandtes Dichtelement und ein nach außen gewandtes Mundstückelement umfasst, die im Einbauzustand dicht ineinander greifend ausgestaltet sind, sowohl die Abdichtung verbessert und gleichzeitig die Haptik für den Benutzer eingehalten werden kann. Der Mundstückverschluss weist also zwei Teile auf, nämlich das das Depot abdichtende Dichtelement und das dem Benutzer zugewandte Mundstückelement. Die Teile greifen beim Zusammenbau und dem Einsatz im Gehäuse ineinander, wobei sie einerseits eine Abdichtung zur Gehäusewandung bewirken und According to the invention, it has been recognized that when the mouthpiece closure comprises a sealing element facing the depot and an outwardly facing mouthpiece element which, in the installed state, are designed to be tightly interlocking, both the sealing improves and at the same time the haptic can be maintained for the user. The mouthpiece closure thus has two parts, namely the depot sealing sealing element and the user facing mouthpiece element. The parts engage in the assembly and use in the housing into each other, on the one hand cause a seal to the housing wall and
andererseits eine Abdichtung zum Depot und natürlich untereinander ebenso. on the other hand, a seal to the depot and, of course, each other as well.
Somit wird zuverlässig mit nur zwei Teilen ein Auslaufen des unverdampften Liquids verhindert. Thus, leakage of the unvaporized liquid is reliably prevented with only two parts.
Vorzugsweise kann vorgesehen sein, dass einerseits das Mundstückelement eine Öffnung und damit komunizierend ein Durchbruchrohr aufweist und andererseits das Dichtelement eine Öffnung und damit komunizierend ein Durchbruchrohr aufweist, wobei das Durchbruchrohr des Mundstückelements eine ersten Außendurchmesser derart aufweist, dass es beim Ineinandergreifen im Durchbruchrohr des Dichtelements mit Passsitz dichtend aufgenommen ist, so dass die Dichtigkeit der Teile zueinander gewährleistet ist. Sinnvollerweise weist das Durchbruchrohr des Dichtelements einen Innendurchmesser abgestimmt auf den Außendurchmesser des Durchbruchrohrs des Mundstückelements auf und nimmt dieses im Einbauzustand dichtend auf. Preferably, it can be provided that, on the one hand, the mouthpiece element has an opening and thus an opening tube and on the other hand, the sealing element has an opening and thus komunizierend a breakthrough tube, wherein the breakthrough tube of the mouthpiece element has a first outer diameter such that it when meshing in the breakthrough tube of the sealing element with Is fit tightly received, so that the tightness of the parts is guaranteed to each other. The breakthrough tube of the sealing element expediently has an inner diameter matched to the outer diameter of the breakthrough tube of the mouthpiece element and absorbs it sealingly in the installed state.
Das Mundstückelement und das Dichtelement werden also quetschend aufeinander aufgepresst, was möglich wird, da das Dichtelement vorzugsweise aus einem Elastomer, wie einem Silikonmaterial, einstückig hergestellt ist und das The mouthpiece element and the sealing element are thus crimped pressed onto each other, which is possible because the sealing element preferably from a Elastomer, such as a silicone material, is made in one piece and the
Mundstückelement vorzugsweise aus Hartplastik, wie einem Thermoplaste oder Duroplaste, einstückig hergestellt ist. Die so bewirkte Abdichtung untereinander wird noch verbessert, wenn das Mouthpiece element preferably made of hard plastic, such as a thermoplastic or thermosets, is made in one piece. The thus caused sealing between them is even better if the
Mundstückelement kappenartig zur teilweisen Aufnahme des Dichtelements ausgebildet ist. Mouthpiece element is designed like a cap for partially receiving the sealing element.
Um das Aneinanderanliegen zu verbessern, können zu dem radial nach Innen von dem Kappenrand vorstehende Stege vorgesehen sein, die im zusammengesetzten Zustand des Mundstückverschlusses das elastische Durchbruchrohr des In order to improve the abutment can be provided to the radially inwardly of the cap edge projecting webs, which in the assembled state of the mouthpiece closure the elastic breakthrough tube of
Dichtelements gegen das umgriffene Durchbruchrohr des Mundstückelements drängen bzw. ein Ausweichen verhindern. Um den Zusammenbau und den Zusammenhalt der Teile zu verbessern, kann vorgesehen sein, dass das Dichtelement in Richtung des Mundstückelements vorstehende Arme aufweist, die in entsprechende Ausnehmungen im Kappenrand eingreifen. Zum Abdichten gegenüber dem Gehäuse ist es sinnvoll, wenn das Dichtelement radial umlaufend beabstandete Dichtlippen am Außenumfang aufweist. Push sealing element against the encompassed breakthrough tube of the mouthpiece element or prevent dodging. In order to improve the assembly and the cohesion of the parts, it can be provided that the sealing element has in the direction of the mouthpiece element projecting arms which engage in corresponding recesses in the cap edge. For sealing relative to the housing, it is useful if the sealing element has radially circumferentially spaced sealing lips on the outer circumference.
Die als Cartomizer bezeichnete Einheit aus Depot und Verdampfer, die in einer zylindrischen Hülle oder Gehäuse enthalten sind, weist also an einem Ende das Mundstück auf, das über ein Inhalationsrohr mit dem Verdampfer kommunizierend verbunden ist. Das Inhalationsrohr ist dabei vom dem Depot umgeben bzw. erstreckt sich von dem Verdampfer durch das Depot hindurch zum Mundstück. Der The unit referred to as cartomizer depot and evaporator, which are contained in a cylindrical shell or housing, thus has at one end to the mouthpiece, which is communicatively connected via an inhalation tube with the evaporator. The inhalation tube is surrounded by the depot or extends from the evaporator through the depot through the mouthpiece. Of the
Mundstückverschluss muss also auch das Inhalationsrohr in einer Weise aufnehmen bzw. dessen Anschluss erlauben, die eine Abdichtung zum Depot gewährleistet. Dazu kann das Dichtelement radial umlaufende beabstandete Dichtlippen am Innenumfang des Durchbruchrohrs aufweisen, Somit kann das Inhalationsrohr zum einfachen Zusammenbau in das Durchbruchrohr eingeschoben werden und die Dichtigkeit ist durch die Dichtlippen gewährleistet. Es versteht sich, dass der Innendurchmesser des Durchbruchrohrs und der Außendurchmesser des Inhalationsrohrs aufeinander abgestimmt sind. Der Mundstückverschluss wird also stopfenartig nach dem Zusammensetzen in das Gehäuse eingeschoben. Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden So mouthpiece closure must also record the inhalation tube in a way or allow its connection, which ensures a seal to the depot. For this purpose, the sealing element may have radially encircling spaced sealing lips on the inner periphery of the breakthrough tube, Thus, the inhalation tube can be inserted into the breakthrough tube for easy assembly and the tightness is ensured by the sealing lips. It is understood that the inner diameter of the breakthrough tube and the outer diameter of the inhalation tube are matched. The mouthpiece closure is thus inserted like a plug after assembly into the housing. Further details of the invention will become apparent from the following

In FIG. 1, only the so-called cartomizer, that is to say the unit from depot 2 and evaporator 3, which is contained in a cylindrical shell 4, is shown by an electric cigarette designated as a whole by 1 which simultaneously serves as a mouthpiece 5 at one end and can be screwed onto a non-shown part at the other end, which comprises the power supply (rechargeable battery) and further electronics, such as pressure switching, etc.
Dieser grundlegende Aufbau ist weitestgehend bekannt. This basic structure is widely known.
Der Verdampfer 3 ist als weitestgehend abgeschlossene Brennkammer 6 ausgeführt ist, die lediglich kleine Eintrittsöffnungen 7 für das Liquid und eine Austrittsöffnung 8 für den Dampf aufweist und eine Heizwendel 9 umfasst, die aus einem Draht mit elektrischem Widerstand besteht. The evaporator 3 is designed as a largely completed combustion chamber 6, which has only small inlet openings 7 for the liquid and an outlet opening 8 for the steam and comprises a heating coil 9, which consists of a wire with electrical resistance.
Die Eintrittsöffnungen 7 erstrecken über die gesamte Höhe der Außenwandung der Brennkammer 6 und sind umlaufend gleichmäßig verteilt. Die Austrittsöffnung 8 ist zentral oberhalb der Heizwendel 9 angeordnet. The inlet openings 7 extend over the entire height of the outer wall of the combustion chamber 6 and are circumferentially evenly distributed. The outlet opening 8 is arranged centrally above the heating coil 9.
Das Depot 2 ist als speicherstofffreier Tank ausgebildet. Es füllt im Wesentlichen die gesamt Hülle 4 aus. Lediglich zwischen Tank und Brennkammer 6 ist ein Liquid durchlässiges Vlies-Gewebe 10 aus Glasfasern angeordnet, das um die kleinen Eintrittsöffnungen 7 gelegt ist. The depot 2 is designed as a storage tank-free tank. It essentially fills the entire shell 4. Only between the tank and the combustion chamber 6, a liquid permeable nonwoven fabric 10 is disposed of glass fibers, which is placed around the small inlet openings 7.
Das durchlässige Gewebe 10 weist einen Bereich 10A höherer Durchlässigkeit und einen Bereich 10B niedrigerer Durchlässigkeit auf, wobei der Bereich 10B niedrigerer Durchlässigkeit an die Eintrittsöffnungen 7 angrenzt. Der Bereich 10B niedrigerer Durchlässigkeit ist also radial um die Brennkammer 6 angeordnet und von dem Bereich 10A höherer Durchlässigkeit umgeben. The permeable fabric 10 has a higher permeability region 10A and a lower permeability region 10B, the lower permeability region 10B being adjacent to the inlet apertures 7.

Es wird so ein Gradient für die Liquidzufuhr in dem Gewebe 10 bewirkt. A gradient for the supply of liquid in the tissue 10 is thus effected.
Zwischen der Austrittsöffnung 8 der Brennkammer 6 für den Dampf und dem Between the outlet opening 8 of the combustion chamber 6 for the steam and the
Mundstück 5 ist zum Mundstück hin sich erstreckendes Inhalationsrohr 1 1 angeordnet. Zwischen dem dem Mundstück zugewandten Ende des Inhalationsrohrs 1 1 und der eigentlichen Ansaugöffnung 12 im Mundstück 5 ist ein Mundstückverschluss 13 vorgesehen, dass das Depot bzw. den Tank zur Ansaugöffnung 12 hin dichtet. Mouthpiece 5 is arranged to the mouthpiece extending inhalation tube 1 1.
