Definitions

  • the present invention relates to a liquefied gas lighter, with a flat flame enlarged in its middle part.
  • the simplest consists in increasing the diameter of the gas evacuation nozzle, but the flow rate of the lighter is then important and an elongated, unattractive flame is obtained.
  • butterfly burners inspired by the technique used on acetylene lamps, that is to say a burner with two heads, the nozzles of which are spaced from one another and inclined towards the axis of the burner.
  • Figures 1 and 2 illustrate two lighters of the prior art comprising a burner which emits two flames intended to come together to form a single enlarged flame.
  • the burner 1 of the lighter 2 comprises two bores 3 and 4 with parallel axes, supplied with gas by the same conduit 5.
  • the flame 6 thus produced remains however relatively narrow, as in the prior art, at less increase the gas flow, which has the disadvantage of simultaneously increasing the length of the flame.
  • the lighter 7 comprises a burner 8 having two divergent bores 9 and 10, arranged symmetrically with respect to the axis of the burner and supplied by the same duct 11.
  • the present invention aims to remedy these drawbacks by proposing a lighter whose flame is flat and wide, and has good stability and a satisfactory height, without however requiring an excessive exit speed and gas flow rate.
  • the invention therefore relates to a gas lighter with a flat flame enlarged in its middle part, of the type comprising a burner comprising two gas outlet nozzles with divergent axes, characterized in that said nozzles have such a shape or are arranged in such a way that at their lower part, they open tangentially to an adjacent surface of the burner or of the body of the lighter, which the gas flow which they emit comes to lick.
  • the lower part of the gas flow of the nozzles will be braked by the adjacent surfaces and the flames they will emit can come together to form only an enlarged flat flame, of a satisfactory height and of great stability.
  • the burner nozzles will be arranged symmetrically with respect to its axis and their upper part will be inclined at least about 30 ° from this axis.
  • the nozzles will have an internal throttle giving them a convergent-divergent profile.
  • this burner 15 comprises two gas outlet nozzles, respectively 16 and 17, supplied with gas by a same conduit 18, formed in the body of the lighter, via a central conduit 19 of the burner.
  • Nozzles 16 and 17 are arranged symmetrically with respect to the axis of the burner and their part upper is inclined on it by an angle of 45 °.
  • the burner has a boss 20, by which it bears on the body of the lighter and on the surface of which tangentially opens the lower part of the nozzles 16 and 17.
  • the gas thus comes to lick the upper surface of the boss 20 , by which it is braked, which has the effect that the two flames emitted by the nozzles 16 and 17 can come together to form a single flame, flat and wide, of a satisfactory height.
  • the central channel 19 communicates with the nozzles 16 and 17 by a restriction giving the assembly a venturi profile favorable to a deceleration of the gases at the outlet of the nozzles.
  • FIG 4 shows another embodiment of the invention, in which the burner is constituted by a substantially cylindrical pin 22, in which are formed slots 23 and 24 constituting the gas discharge nozzles, this burner 22 being simply fitted into a recess 25 of complementary profile of the body of the lighter, supplied with gas by a conduit 27.
  • the lower part of the nozzles 23 and 24 is therefore formed by the surface of the body of the lighter, which the gas leaving the burner comes to lick.
  • the gas is thus braked and the flames emitted by the nozzles 23 and 24 merge into a single flat flame 28, wide in its middle part.
  • the edge 29 of the recess 25 forms a constriction inside the slots 23 and 24, so that, by the diverging effect, the outgoing gas undergoes an increased braking effect which is conducive to obtaining a wide and stable flame.

Claims (5)

1. Gasfeuerzeug mit einer flachen, im mittleren Bereich verbreiterten Flamme mit einem Brenner (15; 22) mit zwei Gasaustrittsdüsen (16, 17; 23, 24) mit divergierenden Achsen, dadurch gekennzeichnet, dass die Düsen eine solche Form aufweisen oder derart angeordnet sind, dass sie an ihrem unteren Abschnitt tangential an eine an den Brenner oder den Körper des Feuerzeugs angrenzende Oberfläche (20) münden, welche vom Gasfluss, den die Düsen ausstossen, bestrichen wird.
2. Feuerzeug nach Anspruch 1, dadurch gekennzeichnet, dass die Düsen (16, 17; 23, 24) symmetrisch zur Achse des Brenners angeordnet sind und dass der obere Abschnitt um einen Winkel von wenigstens 30° zur Achse geneigt ist.
3. Feuerzeug nach Anspruch 1 oder 2, dadurch gekennzeichnet, dass die Düsen eine innere Drossel (29) aufweisen.
4. Feuerzeug nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass der Brenner (15) einen Vorsprung (20) aufweist, über welchen er am Körper des Feuerzeuges anliegt, und dass der untere Abschnitt der Düsen (16,17) tangential auf die Aussenfläche des Vorsprunges mündet.
5. Feuerzeug nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass der Brenner (22) im wesentlichen die Form eines Zylinders aufweist, in welchem die Düsen von zwei seitlichen Schlitzen (16,17) gebildet werden, und dass er in eine Ausnehmung des Feuerzeuges eingepasst ist, an deren Oberfläche die Düsen (16,17) tangential münden.
