Description

Die Erfindung bezieht sich auf ein gasbeheiztes Haarwellgerät mit einem Brennstofftank und einer Gaszuführeinrichtung zwischen dem Brennstofftank und einem Brennraum im Inneren des Haarwellgerätes. Ein solches Haarwellgerät der DE-A-2 948 857.The invention relates to a gas-heated hair waving device with a fuel tank and a gas supply device between the fuel tank and a combustion chamber inside the hair waving device. Such a hair waving device of DE-A-2 948 857.

Bei dem bekannten gasbeheizten Haarwellgerät ist der Brennstofftank fester Bestandteil des Gerätegriffes. Dabei bildet das Gehäuse des Griffteils die Wandung des Brennstofftanks. Das Füllen des Brennstofftanks erfolgt über ein Füllventil, welches an der freien Stirnseite des Griffteils angeordnet ist.In the known gas-heated hair waving device, the fuel tank is an integral part of the device handle. The housing of the handle part forms the wall of the fuel tank. The fuel tank is filled via a filling valve, which is arranged on the free end face of the handle part.

Durch diese Gestaltung kann man den leeren Brennstofftank, genau wie bei einem Feuerzeug, nachfüllen. Dieses Nachfüllen wird im allgemeinen vom Benutzer des Haarwellgerätes durchgeführt. Manchen Benutzern bereitet das Hantieren mit einer unter Druck stehenden Brennstoff-Flüssigkeit jedoch Schwierigkeiten, so daß sie es vorziehen, das Nachfüllen von einem Fachmann vornehmen zu lassen, zumal ein unsachgemäßes Nachfüllen dazu führen kann, daß größere Gasmengen austreten, was eine Unfallgefahr darstellt. Unvermeidlich ist beim Nachfüllen durch den Benutzer des Haarwellgerätes, daß z. B. am Füllventil vorhandener Schmutz in das Haarwellgerät gelangt und sich dort in dem Sinterteil festsetzt, durch welches der Brennstoff aus dem Brennstofftank zum Brennraum strömen muß. Dadurch nimmt mit jedem Nachfüllen der Strömungswiderstand zwischen Brennstofftank und Brennraum zu, so daß die Heizleistung des Haarwellgerätes entsprechend abnimmt.With this design, you can refill the empty fuel tank, just like a lighter. This refilling is generally carried out by the user of the hair waving device. However, some users find it difficult to handle a pressurized fuel liquid, so they prefer to have the refill carried out by a specialist, especially since improper refilling can result in larger amounts of gas escaping, which creates the risk of an accident. It is inevitable when refilling by the user of the hair curler that z. B. dirt on the filling valve gets into the hair waving device and settles there in the sintered part, through which the fuel must flow from the fuel tank to the combustion chamber. As a result, the flow resistance between the fuel tank and the combustion chamber increases with each refill, so that the heating power of the hair waving device decreases accordingly.

Der Erfindung liegt die Aufgabe zugrunde, ein gasbeheiztes Haarwellgerät der eingangs genannten Art so zu gestalten, daß auch technisch wenig geschickte Personen problemlos das leer gewordene Haarwellgerät wieder mit Brennstoff füllen können, ohne daß dabei Verunreinigungen in das Innere des Haarwellgerätes gelangen.The invention has for its object to design a gas-heated hair waving device of the type mentioned so that even technically inexperienced people can easily fill the emptied hair waving device with fuel without impurities getting into the interior of the hair waving device.

Diese Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Maßnahmen gelöst.This object is achieved by the measures specified in claim 1.

Der Hauptvorteil der Erfindung besteht darin, daß beim Füllen mit Brennstoff nicht mehr mit einer unter Druck stehenden Brennstoff-Flüssigkeit hantiert werden muß. Es wird einfach die leere Brennstoffkartusche aus dem Haarwellgerät herausgenommen und eine neue, gefüllte Brennstoffkartusche eingesetzt. Dadurch kann auf das Füllventil am Haarwellgerät verzichtet werden, in welchem sich erfahrungsgemäß leicht Schmutz ansammelt, der dann - wie vorstehend ausgeführt - beim Nachfüllen in das Haarwellgerät gelangen kann.The main advantage of the invention is that when filling with fuel there is no longer a need to handle a pressurized fuel liquid. The empty fuel cartridge is simply removed from the hair waving device and a new, filled fuel cartridge is inserted. This makes it possible to dispense with the filling valve on the hair waving device, in which experience has shown that dirt easily collects, which - as explained above - can then get into the hair waving device when refilling.

Da die Brennstoffkartusche erfindungsgemäß eine durch ein elastisches Bauteil verschlossene Einstechöffnung hat, wird die Einstechnadel dichtend umschlossen, sobald sie in die Kartusche eindringt. Das elastische Bauteil, das vorzugsweise aus einem elastischen Kunstkautschuk mit einem Shore-A-Wert von ca. 60 bis 70 besteht, verschließt die Einstechöffnung sogar dann wieder vollständig, wenn man eine noch nicht vollständig entleerte Brennstoffkartusche wieder aus dem Haarwellgerät herauszieht. Dadurch ist ein Ausströmen von Brenngas aus der Brennstoffkartusche in die Umgebung auf einfache Weise unterbunden, vor allem auch dann, wenn eine vermeintlich leere Brennstoffkartusche dem Haarwellgerät entnommen und z. B. in den Abfalleimer geworden wird.Since, according to the invention, the fuel cartridge has an insertion opening which is closed by an elastic component, the injection needle is enclosed in a sealing manner as soon as it penetrates the cartridge. The elastic component, which preferably consists of an elastic synthetic rubber with a Shore A value of approximately 60 to 70, completely closes the piercing opening even when a fuel cartridge that has not yet been completely emptied is pulled out of the hair waving device. This prevents fuel gas from flowing out of the fuel cartridge into the environment in a simple manner, especially when an allegedly empty fuel cartridge is removed from the hair waving device and z. B. will become in the trash can.

Erfindungsgemäß besteht die Möglichkeit, das Griffteil des Haarwellgerätes und die Brennstoffkartusche aus unterschiedlichen Werkstoffen zu fertigen. Das Griffteil kann z. B. aus einem besonders abriebfesten Kunststoff bestehen, während man für die Brennstoffkartusche ein transparentes, zur Aufbewahrung der Brennstoff-Flüssigkeit besonders geeignetes Material verwendet. Ein solches transparentes Material ermöglicht es, die jeweilige Menge des Brennstoffvorrates mit einem Blick zu erkennen.According to the invention, it is possible to manufacture the handle part of the hair waving device and the fuel cartridge from different materials. The handle part can, for. B. consist of a particularly abrasion-resistant plastic, while using a transparent material for storing the fuel liquid is particularly suitable for the fuel cartridge. Such a transparent material makes it possible to recognize the respective amount of fuel at a glance.

Besonders zweckmäßig ist es, wenn gemäß einer Ausgestaltung der Erfindung die Einstechnnadel eine geschlossene, rotationssymmetrische Spitze hat und vor dieser Spitze eine Querbohrung vorgesehen ist, durch die das Innere des hohlen Nadelschaftes nach außen Verbindung hat. Eine solche Hohlnadel läßt sich im Vergleich zu einer Hohlnadel mit schräg angeschnittener Spitze besonders leicht durch das elastische Bauteil stehen. Weiterhin entsteht durch diese Gestalt der Nadelspitze in dem elastischen Bauteil erfahrungsgemäß eine Lochform, welche sich besonders gut von selbst verschließt, sobald die Nadel wieder herausgezogen wird.It is particularly expedient if, according to one embodiment of the invention, the injection needle has a closed, rotationally symmetrical tip and a transverse bore is provided in front of this tip, through which the interior of the hollow needle shaft has a connection to the outside. In comparison to a hollow needle with an obliquely cut tip, such a hollow needle can be stood particularly easily by the elastic component. Experience has also shown that this shape of the needle tip creates a hole shape in the elastic component which closes itself particularly well as soon as the needle is pulled out again.

Eine besonders funktionssichere Ausführungsform des erfindungsgemäßen Haarwellgerätes ergibt sich mit den in Anspruch 3 genannten Merkmalen des elastischen Bauteils. Die Ausführungsform gemäß Anspruch 4 zeichnet sich zusätzlich durch fertigungstechnische Vorteile beim Zusammenbau der Kartusche aus.A particularly functionally reliable embodiment of the hair waving device according to the invention results from the features of the elastic component mentioned in claim 3. The embodiment according to claim 4 is also characterized by manufacturing advantages when assembling the cartridge.

Vorzugsweise ist bei dem erfindungsgemäßen Haarwellgerät in die Gasaustrittsöffnung der Brennstoffkartusche ein Sinterteil integriert, das gemäß Anspruch 5 in dem elastischen Bauteil und/oder in einem in den Innenraum hineinragenden, die Gasaustrittsöffnung umgebenden Zylinder angeordnet ist. Dieses Sinterteil wirkt in an sich bekannter Weise als Verdampfer für den in flüssiger Form in der Kartusche gespeicherten Brennstoff. Durch seine Anordnung in der auswechselbaren Brennstoffkartusche ergibt sich für das erfindungsgemäße Haarwellgerät der große Vorteil, daß dieses bei jedem Kartuschenwechsel mit einem neuen Verdampfer ausgerüstet wird. Auf diese Weise wird ein schwieriges Problem bisher bekannter Haarwellgeräte vollständig gelöst, bei denen sich das fest im Gerät eingebaute Sinterteil im Laufe der Zeit durch Verschmutzung immer mehr zusetzte, so daß der Strömungswiderstand anstieg und die Heizleistung des Gerätes abnahm.A sintered part is preferably integrated into the gas outlet opening of the fuel cartridge in the hair waving device according to the invention, which is arranged according to claim 5 in the elastic component and / or in a cylinder protruding into the interior surrounding the gas outlet opening. This sintered part acts in a manner known per se as an evaporator for the fuel stored in liquid form in the cartridge. Due to its arrangement in the replaceable fuel cartridge, there is the great advantage for the hair waving device according to the invention that it is equipped with a new evaporator each time the cartridge is changed. In this way, a difficult problem of previously known hair waving devices is completely solved, in which the sintered part permanently installed in the device becomes more and more clogged over the course of time, so that the flow resistance increased and the heating power of the device decreased.

Das erfindungsgemäß in die Kartusche integrierte Sinterteil hat neben der Verdampferfunktion den Vorteil, daß es als Drossel wirkt, denn es begrenzt die pro Zeiteinheit maximal ausströmende Gasmenge. Angenommen, die Dichtung des elastischen Bauteils wäre defekt, so würde das erfindungsgemäß angeordnete Sinterteil verhindern, daß durch momentanes Ausströmen der gesamten Gasmenge ein Sicherheitsrisiko entsteht.In addition to the evaporator function, the sintered part integrated into the cartridge according to the invention has the advantage that it acts as a throttle because it limits the maximum amount of gas flowing out per unit of time. Assuming that the seal of the elastic component would be defective, the sintered part arranged according to the invention would prevent a safety risk being caused by the current flow of the entire gas quantity.

Wie in den Ansprüchen 6, 7 und 8 angegeben, sind weitere vorteilhafte Ausführungsformen des erfindungsgemäßen Haarwellgerätes dadurch gekennzeichnet, daß der Innenraum der Brennstoffkartusche poröses, saugfähiges Material enthält, das beispielsweise aus offenporigem Kunststoffschaum, Kunstfasern und/oder insbesondere aus Aktivkohle bestehen kann. Derartige Materialien sind geeignet, den in der Kartusche gespeicherten Brennstoff von etwa darin enthaltenen Verunreinigungen, wie Schwebeteilchen oder öligen Rückständen, zu reinigen. In der Ausführungsform gemäß Anspruch 8 sorgen sie außerdem dafür, daß auch bei zur Neige gehenden Kartuscheninhalt in jeder Gebrauchslage des Haarwellgerätes der restliche Brennstoff gleichmäßig zum Docht geleitet wird.As stated in claims 6, 7 and 8, further advantageous embodiments of the hair waving device according to the invention are characterized in that the interior of the fuel cartridge contains porous, absorbent material which can consist, for example, of open-pore plastic foam, synthetic fibers and / or in particular activated carbon. Such materials are suitable for cleaning the fuel stored in the cartridge from any impurities contained therein, such as suspended particles or oily residues. In the embodiment according to claim 8, they also ensure that the remaining fuel is evenly conducted to the wick even when the cartridge content is running low in every position of use of the hair waving device.

Zweckmäßig ist es auch, wenn die Brennstoffkartusche transparent ist und durch eine stirnseitige offene Kappe im Griffteil des Haarwellgerätes gehalten wird. Durch diese Ausgestaltung wird erreicht, daß man auch bei in das Haarwellgerät eingesetzter Brennstoffkartusche von der rückwärtigen Stirnseite des Griffteils her mit einem Blick erkennen kann, ob noch flüssiger Brennstoff in der Kartusche vorhanden ist.It is also expedient if the fuel cartridge is transparent and is held in the handle part of the hair waving device by an open cap on the front. This configuration ensures that, even when the fuel cartridge is inserted into the hair waving device, one can see at a glance from the rear face of the handle part whether liquid fuel is still present in the cartridge.

Eine andere vorteilhafte Ausgestaltung der Erfindung besteht darin, daß die Kappe auf das Griffteil aufschraubbar ist. Durch diese Maßnahme kann man erreichen, daß durch die Schraubbewegung der Kappe die Brennstoffkartusche genau axial in das Griffteil geschoben wird, bis die Einstechnadel das elastische Bauteil durchdrungen hat und damit das Haarwellgerät betriebsbereit ist.Another advantageous embodiment of the invention is that the cap can be screwed onto the handle part. By this measure it can be achieved that the screw cartridge moves the fuel cartridge exactly axially into the handle part until the injection needle has penetrated the elastic component and the hair waving device is thus ready for use.

Beispiele der zahlreichen Ausführungsmöglichkeiten der Erfindung sind in der Zeichnung dargestellt und werden nachfolgend beschrieben.Examples of the numerous possible embodiments of the invention are shown in the drawing and are described below.

  • Figur 2 eine vergrößerte Darstellung eines Details des Haarwellgerätes gemäß Figur 1;
  • Figur 3 eine andere erfindungsgemäße Ausführungsform des in Figur 2 dargestellten Details.
It shows
  • FIG. 1 shows an embodiment of a hair waving device designed according to the invention, largely as a longitudinal step and partially as a side view;
  • Figure 2 is an enlarged view of a detail of the hair waving device according to Figure 1;
  • Figure 3 shows another embodiment of the invention according to the detail shown in Figure 2.

Das in Figur 1 dargestellte Haarwellgerät besteht im wesentlichen aus einem Griffteil 1, in dem ein Ende eines Stabkörpers 2 gehalten ist. Im Stabkörper 2 ist eine gasbetriebene Heizung 3 angeordnet, der Gas über eine Gaszuführeinrichtung 4 zugeleitet wird, so daß dieses in einem Brennraum 5 verbrennen kann. Die Gaszuführeinrichtung 4 weist eine Ventileinrichtung 6 auf, welche manuell mittels eines Schalters 7 zu öffnen und zu schließen ist, wodurch Gaszufuhr vom Brennstofftank 8 zur Heizung 3 freigegeben bzw. gesperrt wird.The hair waving device shown in Figure 1 consists essentially of a handle part 1, in which one end of a rod body 2 is held. A gas-operated heater 3 is arranged in the rod body 2, and the gas is supplied via a gas supply device 4 so that it can burn in a combustion chamber 5. The gas supply device 4 has a valve device 6 which can be opened and closed manually by means of a switch 7, as a result of which gas supply from the fuel tank 8 to the heater 3 is released or blocked.

Erfindungsgemäß ist der Brennstofftank 8 als Brennstoffkartusche 9 ausgebildet, die in der Zeichnung von rechts her in das Griffteil 1 eingeschoben ist. Das Gas gelangt aus der Brennstoffkartusche 9 über die hohle Einstechnadel 10 zur Gaszuführeinrichtung 4 und damit zur Heizung 3. Erfindungsgemäß bevorzugte Beispiele für die Gestaltung der Brennstoffkartusche 9 im Bereich der Einstechnadel 10 und bezüglich der Form der Einstechnadel 10 sind in den Figuren 2 und 3 dargestellt.According to the invention, the fuel tank 8 is designed as a fuel cartridge 9, which is inserted into the handle part 1 from the right in the drawing. The gas passes from the fuel cartridge 9 via the hollow injection needle 10 to the gas supply device 4 and thus to the heater 3. Examples according to the invention for the design of the fuel cartridge 9 in the area of the injection needle 10 and with regard to the shape of the injection needle 10 are shown in FIGS. 2 and 3 .

Man erkennt in Figur 2 zunächst, daß die Brennstoffkartusche 9 einen in ihr Inneres hineingezogene Zylinder 11 hat. In diesem Zylinder 11 sitzt das topfförmig ausgebildete, elastische Bauteil 12, welches in diesem Zylinder in der Zeichnung von rechts her eingeschoben wurde. Koaxial zum elastischen Bauteil 12 befindet sich in der kalottenförmigen Stirnfläche 13 der Brennstoffkartusche 9 eine Einstechöffnung 14, die bei nicht in das Griffteil 1 eingeschobener Brennstoffkartusche 9 von dem elastischen Bauteil 12 verschlossen ist. Wird die Brennstoffkartusche 9 jedoch in das Griffteil 1 geschoben, so gelangt die Einstechnadel 10 durch diese Einstechöffnung 14 und durchsticht die Stirnfläche des elastischen Bauteils 12, was in Figur 2 zu erkennen ist. Damit das Durchstechen leicht erfolgt, hat die Einstechnadel 10 eine rotationssymmetrische geschlossene Spitze 15. Durch die Querbohrung 16 kann das Gas aus der Kartusche in den hohlen Schaft der Einstechnadel 10 und weiter zum Brennraum 5 strömen.It can first be seen in FIG. 2 that the fuel cartridge 9 has a cylinder 11 drawn into its interior. In this cylinder 11 sits the cup-shaped, elastic component 12, which was inserted in this cylinder from the right in the drawing. Coaxial to the elastic component 12, there is an insertion opening 14 in the spherical end face 13 of the fuel cartridge 9, which is closed by the elastic component 12 when the fuel cartridge 9 is not inserted into the handle part 1. However, if the fuel cartridge 9 is pushed into the handle part 1, the injection needle 10 passes through this piercing opening 14 and pierces the end face of the elastic component 12, which can be seen in FIG. 2. So that the piercing is easy, the injection needle 10 has a rotationally symmetrical closed tip 15. The gas can flow from the cartridge into the hollow shaft of the injection needle 10 and further to the combustion chamber 5 through the transverse bore 16.

Wie bei gasbetriebenen Haarwellgeräten üblich, ist ein Sinterteil 17 vorgesehen, das dazu dient, den vom Docht 18 zugeführten flüssigen Brennstoff zu verdampfen. Für die Erfindung wesentlich ist, daß das Sinterteil 17 in der Brennstoffkartusche 9 angeordnet ist, so daß mit jedem Auswechseln einer Brennstoffkartusche 9 jeweils auch ein neues Sinterteil 17 zur Verwendung gelangt.As is usual with gas-powered hair waving devices, a sintered part 17 is provided which serves to evaporate the liquid fuel supplied by the wick 18. It is essential for the invention that the sintered part 17 is arranged in the fuel cartridge 9, so that each time a fuel cartridge 9 is replaced, a new sintered part 17 is used.

In der aus fertigungstechnischen Gründen bevorzugten Ausführungsform der Erfindung gemäß Figur 3, ist das elastische Bauteil 12' als Scheibe oder Stopfen ausgebildet und z. B. mittels eines form- und/oder kraftschlüssig in der erweiterten Einstechöffnung 14 festgesetzten Preßringes 21 dichtend in der Einstechöffnung 14 befestigt. Als Verdampfer dient hier das Sinterteil 17', das in dem in den Innenraum der Brennstoffkartusche hineinragenden Zylinder 11 angeordnet ist und an dem der Docht 18 mündet. Der Docht 18 ist - wie in Figur 3 angedeutet - vorzugsweise im übrigen so geführt, daß er zumindest abschnittweise an der Innenwandung der Kartusche anliegt und insbesondere ihr in einer vollständigen Umfangswindung folgt. Diese Anordnung des Dochtes hat den Vorteil, daß er auch bei nahezu entleerter Kartusche immer wieder vom Brennstoffrest erreicht wird und diesen zum Verdampfer leitet.In the preferred embodiment of the invention according to FIG. 3 for manufacturing reasons, the elastic component 12 'is designed as a disk or stopper and z. B. by means of a positive and / or non-positively fixed in the enlarged insertion opening 14 press ring 21 sealed in the insertion opening 14. The sintered part 17 ′, which is arranged in the cylinder 11 projecting into the interior of the fuel cartridge and on which the wick 18 opens, serves as the evaporator. As indicated in FIG. 3, the wick 18 is preferably guided in such a way that it bears at least in sections on the inner wall of the cartridge and in particular follows it in a complete circumferential turn. The The arrangement of the wick has the advantage that it is always reached by the fuel residue even when the cartridge is almost empty and directs it to the evaporator.

Eine weitere vorteilhafte Variante des erfindungsgemäßen Haarwellgerätes besteht darin, daß - wie ebenfalls in Figur 3 angedeutet - der Innenraum der Brennstoffkartusche 9 poröses, saugfähiges Material 23 enthält, das, wenn es mit dem Docht 18 in Kontakt steht, dessen Funktion unterstützt und im übrigen dem Brennstoff etwaige Verunreinigungen entzieht.Another advantageous variant of the hair waving device according to the invention is that - as also indicated in Figure 3 - the interior of the fuel cartridge 9 contains porous, absorbent material 23 which, when it is in contact with the wick 18, supports its function and the rest Fuel removes any contaminants.

Eine zusätzliche nützliche Maßnahme, die verhindert, daß beim Einsetzen einer neuen Kartusche Schmutz in den Brenner des Haarwellgerätes gelangt, besteht im Rahmen der vorliegenden Erfindung darin, daß die Einstechöffnung 14 der Kartusche 9, wie Figur 3 zeigt, mit einer glattförmigen, dünnwandigen Schutzkappe 22 abgedeckt ist, die vor dem Einsetzen der Kartusche leicht und gründlich gereinigt werden kann und die dem Eindringen der spitzen Einstechnadel 10 keinen merklichen Widerstand entgegensetzt. Außerdem bürgt die Unversehrtheit dieser Schutzkappe 22 dafür, daß es sich um eine neue Kartusche handelt, der noch kein Brennstoff entnommen wurde.An additional useful measure, which prevents dirt from getting into the burner of the hair waving device when a new cartridge is inserted, consists in the context of the present invention in that the piercing opening 14 of the cartridge 9, as shown in FIG. 3, has a smooth, thin-walled protective cap 22 is covered, which can be easily and thoroughly cleaned before inserting the cartridge and which does not provide any noticeable resistance to the penetration of the pointed injection needle 10. In addition, the integrity of this protective cap 22 guarantees that it is a new cartridge from which no fuel has yet been removed.

Zur Erläuterung eines weiteren Details sei nochmals auf Figur 1 Bezug genommen. Man erkennt dort, daß die Brennstoffkartusche 9 durch eine Kappe 19, welche von der rückwärtigen Stirnseite herauf das Griffteil 1 geschraubt ist, daran gehindert wird, aus dem Griffteil 1 herauszufallen. Diese Kappe 19 hat eine stirnseitige Öffnung 20, durch die die in das Griffteil 1 eingeschobene Brennstoffkartusche 9 von außen sichtbar ist. Fertigt man die Brennstoffkartusche 9 aus einem transparenten Kunststoff, so kann man mit einem Blick durch die Öffnung 20 erkennen, ob sich in der Brennstoffkartusche 9 noch Brennstoff-Flüssigkeit befindet.To explain a further detail, reference is again made to FIG. 1. It can be seen there that the fuel cartridge 9 is prevented from falling out of the handle part 1 by a cap 19 which is screwed up from the rear end side of the handle part 1. This cap 19 has an end opening 20 through which the fuel cartridge 9 inserted into the handle part 1 is visible from the outside. If the fuel cartridge 9 is made of a transparent plastic, it can be seen at a glance through the opening 20 whether there is still fuel-liquid in the fuel cartridge 9.

Soll eine leer gewordene Brennstoffkartusche 9 gegen volle ausgewechselt werden, dann ist zunächst die Kappe 19 abzuschrauben. Anschließend ist die Brennstoffkartusche 9 aus dem Griffteil 1 herauszuziehen. Sobald die Einstechnadel 10 aus dem elastischen Bauteil 12 herausgelangt ist, verschließt dieses die Einstechöffnung 14 gasdicht, so daß der Brennstoffkartusche 9 auch dann kein Gas entströmen kann, wenn diese beim Herausziehen noch nicht vollständig leer sein sollte. Sodann kann eine neue Brennstoffkartusche 9 eingeschoben werden. Dabei durchsticht die Einstechnadel 10 gegebenenfalls zunächst die Schutzkappe 22 und dann das elastische Bauteil 12 und stellt über ihre Querbohrung 16 eine Verbindung zur Gaszuführeinrichtung 4 und damit zur Heizung 3 her. Die axiale Bewegung der Brennstoffkartusche zum Zwecke des Durchstechens des elastischen Bauteils 12 kann dadurch erzeugt werden, daß die Kappe 19 auf das Griffteil 1 geschraubt wird und sich dabei axial genau so weit verschiebt, daß die Einstechnadel 10 um ein vorgegebenes Maß in die Brennstoffkartusche 9 eindringt.If a fuel cartridge 9 that has become empty is to be replaced by a full one, then the cap 19 must first be unscrewed. Then pull the fuel cartridge 9 out of the handle part 1. As soon as the injection needle 10 has come out of the elastic component 12, it closes the insertion opening 14 in a gas-tight manner, so that the fuel cartridge 9 cannot release gas even if it should not be completely empty when it is pulled out. A new fuel cartridge 9 can then be inserted. The puncture needle 10 may first pierce the protective cap 22 and then the elastic component 12 and establish a connection to the gas supply device 4 and thus to the heater 3 via its transverse bore 16. The axial movement of the fuel cartridge for the purpose of piercing the elastic component 12 can be generated in that the cap 19 is screwed onto the handle part 1 and thereby moves axially exactly to the extent that the injection needle 10 penetrates the fuel cartridge 9 by a predetermined amount .
