Description

Die vorliegende Erfindung betrifft Feuerzeuge, insbesondere mehrflammige Feuerzeuge mit Jetflamme. Ein solches Feuerzeug ist aus Dokument US-A-6 152 727 schon bekannt.The present invention relates to lighters, in particular multi-flame lighters with jet flame. Such a lighter is already known from document US-A-6 152 727.

Mehrflammige Feuerzeuge mit Jetflamme sind im Stand der Technik bekannt, insbesondere zweiflammige Feuerzeuge. Im Stand der Technik sind beispielsweise Feuerzeuge mit zwei parallel angeordneten Jet-Flammen bekannt, um beispielsweise breite Zigarren anzuzünden. Im Stand der Technik sind Feuerzeuge mit Jetflammen-Düsen bekannt, bei denen ein reines Brenngas aus einer oder mehreren Öffnungen ausströmt und mit der umgebenden Luft verbrennt. Im Stand der Technik sind ebenfalls Feuerzeuge bekannt, bei denen die Flammendüse als eine Brennerdüse ausgeführt ist, bei der ein Brenngas mit Luft gemischt wird, bevor das Gemisch entzündet wird. Derartige Brennerdüsen-Feuerzeuge sind als Jetflamm-Feuerzeuge bekannt. Im Stand der Technik sind ebenfalls zweiflammige Feuerzeuge mit einer Flammendüse und einer Brennerdüse bekannt.Multi-flame lighters with jet flame are known in the art, especially two-lighters. For example, lighters with two jet flames arranged in parallel are known in the prior art in order, for example, to light wide cigars. In the prior art lighters with jet flame nozzles are known in which a pure fuel gas flows out of one or more openings and burns with the surrounding air. Also known in the art are lighters in which the flame nozzle is designed as a burner nozzle in which a fuel gas is mixed with air before the mixture is ignited. Such burner nozzle lighters are known as jet flame lighters. Also known in the art are two-bladed lighters having a flame nozzle and a burner nozzle.

Alle bisherigen Feuerzeuge haben den Nachteil, dass sie nur wenige leistungsschwache Düsen zur Verfügung stellen, die keine ultraheißen Jetflammen liefern. Es ist daher möglich, dass die Zeit bis zur wirksamen Entzündung beispielsweise einer Zigarette zu lange dauert.All previous lighters have the disadvantage that they provide only a few low-performance nozzles that do not deliver ultra-hot jet flames. It is therefore possible that the time to effective inflammation, for example, of a cigarette takes too long.

Es ist daher eine Aufgabe der vorliegenden Erfindung, ein Feuerzeug bereitzustellen, das durch eine erfindungsgemäße Anordnung von mehreren Jetflammen-Düsen zuverlässig sehr heiße Jetflammen zur Verfügung stellt.It is therefore an object of the present invention to provide a lighter that reliably provides very hot jet flames by an inventive arrangement of a plurality of jet flame nozzles.

Das erfindungsgemäße Feuerzeug weist mindestens drei in einem Kopf angeordnete Jetflammen-Düsen auf. Das erfindungsgemäße Feuerzeug ist dadurch gekennzeichnet, dass die Jetflammen-Düsen so angeordnet sind, dass die Achsen der Jetflammen-Düsen sich zumindest abschnittsweise annähern. Damit kann erreicht werden, dass wenn eine Flamme in einer der Düsen erlischt, sie durch die eine oder die beiden anderen Düsen wieder entzündet wird. Ferner wird die Temperatur der Flammen im Näherungsbereich besonders hoch.The lighter according to the invention has at least three jet flame nozzles arranged in a head. The lighter according to the invention is characterized in that the jet flame nozzles are arranged so that the axes of the jet flame nozzles approach each other at least in sections. It can thus be achieved that, when a flame in one of the nozzles extinguishes, it is re-ignited by the one or the other two nozzles. Furthermore, the temperature of the flames in the proximity region becomes particularly high.

Bevorzugt nähert sich zumindest die Achse von einer der mindestens drei Jetflammen-Düsen jeweils mindestens den Achsen zweier anderer Jetflammen-Düsen zumindest abschnittsweise an. Damit wird erreicht, dass jede der erzeugten Flammen sich dem Bereich von mindestens zwei anderen Flammen annähert, die im Fall des Erlöschens einer Flamme diese sicher wieder entzünden können.Preferably, at least the axis of at least one of the at least three jet flame nozzles at least partially approaches at least the axes of two other jet flame nozzles. This ensures that each of the generated flames is within the range of at least approaching two other flames which, in the event of a flame being extinguished, can safely re-ignite them.

Das erfindungsgemäße Feuerzeug weist mindestens drei Jetflammen-Düsen auf, deren Jet-Flammen sich im Betrieb jeweils paarweise einander nähern und sich bevorzugt schneiden. Dadurch kann sichergestellt werden, dass selbst, wenn ein Wassertropfen eine der Flammen löscht, die entsprechende Düse durch den Gasstrom und die Hitze der beiden anderen Flammen schnell trocknet und wieder arbeiten kann. Durch die erfindungsgemäße Anordnung der Flammen bzw. Brennerdüsen trifft der Gasstrom auf mindestens zwei angrenzende Flammen, die den Gasstrom sofort wieder entzünden. Die Flammen konvergieren bevorzugt in einem gemeinsamen Bereich.The lighter according to the invention has at least three jet flame nozzles whose jet flames approach each other in pairs during operation and preferably intersect. This can ensure that even if a drop of water extinguishes one of the flames, the corresponding nozzle can be quickly dried by the gas flow and the heat of the other two flames and work again. As a result of the arrangement of the flames or burner nozzles according to the invention, the gas stream strikes at least two adjacent flames, which ignite the gas stream immediately. The flames preferably converge in a common area.

Die Achsen von mindestens drei der Flammen- oder Brennerdüsen liegen bevorzugt im wesentlichen in einer Kegeloberfläche. Die Jetflammen-Düsen können dabei auf einer Höhe in der Kegeloberfläche liegen, um sicherzustellen, dass keine der Flammen die anderen zu sehr überragt.
Die Achsen der Brennerdüsen können im wesentlichen in einem einzigen Punkt zusammenlaufen, in dem die mindestens drei Flammen sich berühren oder zu einer einzelnen verschmelzen können. Bei der Verwendung von drei Jetflammen-Düsen liegen die drei Jetflammen-Düsen im Wesentlichen auf den Kanten einer dreiseitigen Pyramide und weisen gemeinsam auf die Spitze der Pyramide, an der sich im Betrieb die drei Flammen zu einer einzigen vereinigen.The axes of at least three of the flame or burner nozzles are preferably substantially in a conical surface. The jet flame nozzles can be at a height in the cone surface to ensure that none of the flames tower over the others too much.
The axes of the burner nozzles may converge substantially at a single point where the at least three flames may touch or merge into a single point. When using three jet flame nozzles, the three jet flame nozzles lie essentially on the edges of a three-sided pyramid and point together to the top of the pyramid, in which the three flames unite in operation.

Die Jetflammen-Düsen können um eine Achse drehsymmetrisch angeordnet sein. Dadurch wird erreicht, dass die gemeinsame Flamme eine symmetrische Form annimmt. Eine derartige dreiflammige Ausführungsform, bei der die drei Jetflammen-Düsen drehsymmetrisch auf einer Kegeloberfläche angeordnet sind und bei der die drei Flammen in einem Punkt zusammenlaufen, ist beispielsweise in den Figuren 1 und 2 dargestellt. In dem Kreuzungspunkt werden besonders hohe Temperaturen erzielt. Die Jetflammen-Düsen können auch auf einem Halbkegel angeordnet sein, um beispielsweise eine gleiche Grundform für eine drei- oder vierflammige Ausführungsform ohne zusätzlichen Konstruktions- oder Werkzeugaufwand bereitzustellen.The jet flame nozzles can be arranged rotationally symmetrically about an axis. This ensures that the common flame assumes a symmetrical shape. Such a three-flame embodiment, in which the three jet flame nozzles are arranged rotationally symmetrically on a conical surface and in which the three flames converge in one point, is shown for example in FIGS. 1 and 2. In the crossing point particularly high temperatures are achieved. The jet flame nozzles can also be arranged on a half cone to provide, for example, a same basic shape for a three- or four-flame embodiment without additional design or tooling.

Die Achsen der mindestens drei Jetflammen-Düsen können eine gemeinsame Kegeloberfläche auf einer gleichen Höhe der Kegeloberfläche berühren und mit der Kegelachse im Wesentlichen einen gemeinsamen Winkel bilden. Bei dieser Ausführungsform treffen sich die Achsen der mindestens drei Jetflammen-Düsen nicht in einem einzelnen Punkt, sondern liegen windschief zueinander. Bei einer drehsymmetrischen Anordnung verschmilzt die Spitze einer Flamme mit der Basis einer benachbarten der anderen Flamme. Aus der Anordnung der zusammenlaufenden Flammen ergibt sich eine gemeinsame Flamme, die durch die Schrägstellung der Jetflammen-Düsen zu einer Rotation der gemeinsamen Flamme führt. Eine Aufsicht auf eine derartige, dreiflammige Jetflammen-Düsen-Anordnung ist in Figur 3 dargestellt.The axes of the at least three jet flame nozzles can touch a common cone surface at a same height of the conical surface and form a common angle with the cone axis substantially. In this embodiment, the axes of the at least three jet flame nozzles do not meet a single point, but are skewed. In a rotationally symmetric arrangement, the tip of one flame merges with the base of an adjacent one of the other flame. From the arrangement of the converging flames results in a common flame, which leads by the inclination of the jet flame nozzles to a rotation of the common flame. A plan view of such a three-flame jet flame nozzle arrangement is shown in FIG.

Bevorzugt werden die mindestens drei Jetflammen-Düsen in einem einzelnen integral ausgeführten Jetflammen-Düsen-Block zusammengefasst. Damit kann die Anzahl der Bauteile in dem Feuerzeug verringert werden, was die Herstellungskosten senkt.Preferably, the at least three jet flame nozzles are combined in a single integrally embodied jet flame nozzle block. Thus, the number of components in the lighter can be reduced, which lowers the manufacturing cost.

Bevorzugt weist das Feuerzeug weiterhin ein Steuerventil auf, mit dem einzelne oder Gruppen von Jetflammen-Düsen betätigt werden können. Ein Steuerventil zum Steuern einzelner Jetflammen-Düsen kann dazu beitragen, den Gasverbrauch des brennenden Feuerzeuges bei Windstille zu verringern und damit die Benutzungs- bzw. Brenndauer des Feuerzeuges zu erhöhen.Preferably, the lighter further comprises a control valve with which individual or groups of jet flame nozzles can be actuated. A control valve for controlling individual jet flame nozzles can help to reduce the gas consumption of the burning lighter in calm conditions and thus to increase the life of the lighter.

Mindestens drei der Jetflammen-Düsen können als Brennerdüsen ausgeführt werden. Brennerdüsen haben im Vergleich zu Jetflammen-Düsen den Nachteil des höheren Gasverbrauches. Durch eine entsprechende Auswahl der Brennerdüsen beispielsweise in Kombination mit einer zusätzlichen Flammendüse kann ein voteilhaftes Feuerzeug verwirklicht werden. Die Flammendüse kann beispielsweise in der Mitte der Brennerdüsen angeordnet sein und durch das Öffnen eines Deckels aktiviert werden. Bei Betätigung eines Zündschiebers werden die drei Brennerdüsen gezündet, und erlöschen, wenn der Zündschieber wieder losgelassen wird, während eine Zündflamme weiter brennt, solange der Deckel des Feuerzeuges geöffnet bleibt. Die Zündflamme wird beim Schießen des Deckels durch eine Sperrung der Gaszufuhr gelöscht.At least three of the jet flame nozzles can be designed as burner nozzles. Burner nozzles have the disadvantage of higher gas consumption compared to jet flame nozzles. By an appropriate selection of the burner nozzles, for example in combination with an additional flame nozzle, a voteilhaftes lighter can be realized. The flame nozzle can be arranged for example in the middle of the burner nozzles and activated by opening a lid. Upon actuation of an ignition slide, the three burner nozzles are ignited and extinguished when the ignition slide is released while a pilot flame continues to burn while the lid of the lighter remains open. The pilot light is extinguished when the lid is fired by blocking the gas supply.

Bevorzugt weist das Feuerzeug eine Abdeckung zum Schutz der Jetflammen-Düsen bzw. Brennerdüsen gegen Verunreinigung auf. Die Abdeckung dient zum Schutz gegen Staub, Schmutz und Beschädigung der Brennerdüsen.Preferably, the lighter has a cover for protecting the jet flame nozzles or burner nozzles against contamination. The cover is designed to protect against dust, dirt and damage to the burner nozzles.

Das erfindungsgemäße Feuerzeug kann, mit einer Nachfüllvorrichtung versehen sein, um einen Gastank des Feuerzeuges nachzufüllen. Das Feuerzeug kann weiter mit einer Flammenhöhen-Regulierung versehen sein, um die Flammenhöhe den Bedürfnissen eines Benutzers anpassen zu können. Das Feuerzeug kann mit einer üblichen Zündvorrichtung wie beispielsweise einer piezoelektrischen Zündvorrichtung versehen sein. Andere Zündvorrichtungen wie Batterie-Zündvorrichtungen können in dem Feuerzeug gemäß dieser Erfindung ebenfalls verwendet werden.The lighter according to the invention may be provided with a refilling device to refill a gas tank of the lighter. The lighter may be further provided with flame height regulation to adjust the flame height to the needs of a user. The lighter may be provided with a conventional ignition device such as a piezoelectric igniter. Other Ignition devices such as battery ignitors may also be used in the lighter of this invention.

Das Feuerzeug ist weiter mit einem zentralen Gasventil 8 ausgestattet, um die drei Jetflammen-Düsen gleichzeitig mit Gas zu versorgen. Die Zündvorrichtung 10 und das Gasventil 8 werden über einen zentralen Zündschieber 16 betätigt. Beim Herabdrücken des Zündschiebers wird zuerst das Gasventil 8 und dann das piezoelektrische Zündelement 10 betätigt, um ein aus den Brennerdüsen austretendes Gas-Luft-Gemisch zu entzünden. Die Brennerdüsen erzeugen jeweils spitz zulaufende Flammen, die als schwarze Dreiecke dargestellt sind, die sich in dem Punkt 6 vereinigen. In der unteren Ansicht ist ein Nachfüllventil durch den Kreis 14 angedeutet. In der oberen Aufsicht sind die drei Brennerdüsen 4 als in einem gleichseitigen Dreieck angeordnet zu erkennen.

Wie in Figur 2 gezeigt, deutet der Kreis 18 eine Zündelektrode für eine piezoelektrische Zündvorrichtung an.FIG. 4 shows another embodiment of a four-flame lighter according to the invention in an upper plan view. The four burner nozzles 4, 4 ', 4 ", 4"' face one another, so that the flames lie substantially at a point in the middle above the plane of the drawing approach each other or converge. At high flame heights, the flames will touch in the middle. In this embodiment, each of the flames approaches each other. As shown in Fig. 2, the circle 18 indicates an ignition electrode for a piezoelectric igniter.

Es ist zu betonen, dass alle vorstehenden Ausführungsformen lediglich beispielhaft sind. Mehrflammige, wie beispielsweise 5-, 6- oder 7-flammige Feuerzeuge sollen auch unter den Schutzumfang der vorliegenden Erfindung fallen. Bei 6-flammigen Ausführungsformen können beispielsweise jeweils drei der Jetflammen-Düsen auf einer Kegelfläche liegen, während die anderen drei auf einer zweiten, anderen Kegelfläche liegen.It should be emphasized that all the above embodiments are merely exemplary. Multi-flame, such as 5, 6 or 7-flame lighters are also intended to fall within the scope of the present invention. In the case of 6-flame embodiments, for example, three of the jet flame nozzles can each lie on one conical surface, while the other three lie on a second, different conical surface.
