Definitions

  • the present invention generally relates to a fire-proof device for generating a hot gas for the smoke-free inhalation of nicotine and / or additives.
  • mainstream smoke When smoking a conventional cigarette tobacco is burned and the resulting smoke from this smoke is inhaled (mainstream smoke) or released to the environment (sidestream smoke).
  • the mainstream smoke is largely responsible for the health of the consumer, but provides him with the desired enjoyment.
  • the sidestream smoke is largely responsible for the health damage of passive smokers and is desired by neither the passive smokers nor the consumer.
  • Actions and devices based thereon for the smoke-free inhalation of nicotine and / or additives have the aim to offer the consumer a substitute for the conventional cigarette, which causes a much lower damage to health of consumers and third parties, preferably no damage to health of consumers and third parties, but this Retains the consumer experience of a conventional cigarette.
  • WO 2008/113420 A1 describes a process for the volatilization of active substances and / or flavorings for the purpose of delivering an inhalable aerosol, wherein combustion gases of a combustible gas, which is preferably substantially burned with excess air, partially or completely, optionally mixed with ambient air, by an active and / or flavorant depot be guided and wherein a desired temperature by the proportion of combustion gases and optionally by the mixing ratio of these combustion gases with ambient air is selectable.
  • Such a method preferably for inhaling a nicotine-flavored mixture, is made possible by the clean combustion of an air-gas mixture, i.
  • the exhaust gases consist of nitrogen, harmless carbon dioxide, water and possibly residual oxygen and can thus be safely inhaled.
  • WO 2008/113420 A1 describes, inter alia, a heating rod, which is the source of energy and heat of the entire system and controlled in operation, controlled by the suction of the user, provides sufficient energy in the form of hot gases available to a sufficient amount of nicotine and other active and / or flavoring and / or to evaporate further additives from a replaceable mouthpiece.
  • the object of the present invention is therefore a device similar to one as in WO 2008/113420 A1 described heating rod for generating a hot gas for smoke-free inhalation of nicotine and / or additives, ready to provide, from the operation but no fire danger.
  • the device Since the in WO 2008/113420 A1 described device burns liquefied gas in operation and thus in principle fire hazard, the device must be such that if the consumer does not suck on the mouthpiece and the device falls down during operation or drop, the energy emitted by the burner to the environment not to ignite solid Materials, especially papers and textiles of any kind is sufficient.
  • Such a heater may, for example, in a as in WO 2008/113420 A1 described device advantageously used as a so-called heating rod. Accordingly, it is understood that in addition those relevant features can be used, which in WO 2008/113420 A1 are shown and described, which is hereby incorporated by reference to avoid repetition.
  • heating rod and mouthpiece have a basically cylindrical shape and a diameter between about 6 to about 14 mm, preferably between about 8 and 11 mm and a Length of about 50 to about 150 mm, preferably between about 75 and about 105 mm.
  • the general advantages of the heater are similar to those of WO 2008/113420 A1 Eg ease of use by the user, which is also supported by a very low weight, so that the device is easily portable in the mouth without having to be permanently held in the hand.
  • the reusability of such a heating element is to mention in particular.
  • the invention makes it possible by the particular configuration and arrangement of a first (inner) and second (outer) catalyst to significantly lower the temperatures on the outer burner side of the heating without affecting the functions of the heater, such as. The heating of the air or igniting the heater.
  • the risk of fire during operation e.g. when lying down or dropping the device significantly reduced.
  • the invention also contributes to the safety of the heater during use, for. B. by unintentional touching the burner-side end of the heater.
  • a further advantage of the invention is that the arrangement of two catalysts achieves that the first catalyst reaches a suitable operating temperature more quickly (than a corresponding one-piece catalyst of first and second catalyst), ie even with smaller amounts of gas, and in operation can last longer (as this is in the Inside the combustion chamber is located) without representing a risk of injury or fire.
  • the regulator valve is controllable by means of a generated by the suction of a user vacuum and / or air flow.
  • the regulator valve comprises a control body, and preferably means for generating a restoring force, wherein the control body preferably has at least a first, minimally open and a second, open state and the control body by means of the generated negative pressure and / or air flow from the minimum open state, if necessary is displaceable against a restoring force in the open state.
  • service flame open
  • pilot flame minimum open
  • minimally open or the corresponding expressions “minimum flow” or “minimum flow cross-section” is to be understood as a state in which a small amount of gas flows through which is just sufficient so that the flame in the downstream burner does not extinguish.
  • the resulting operating condition also called a pilot flame, allows the user to make several moves without having to reignite the burner every time, while consuming as little gas as possible, which benefits a more compact design of the device.
  • the first catalytic converter and the minimally open state of the regulator valve are dimensioned such that the liquid-gas / air mixture completely burns on the first catalytic converter in the minimally open state of the regulator valve.
  • the second catalyst practically does not heat up during the so-called standby (pilot flame only). It is thus possible to further reduce the temperature at the burner end during a considerable period of use and thus to increase safety.
  • the second catalyst, if appropriate the first catalyst, and the open state of the regulator valve are dimensioned such that the liquid gas-air mixture burns completely in the open state of the regulator valve on the first and second catalyst.
  • the first catalyst preferably comprises a carrier body and a catalytic coating for the total oxidation of hydrocarbons, preferably for the total oxidation of butane, propane or mixtures thereof.
  • the coating of the first catalyst preferably contains z.
  • platinum palladium and / or non-noble metal mixed oxides.
  • the carrier body of the first catalyst is preferably a metallic carrier body, for. As an annular or S-shaped wire, which can further enhance the effect described above on the operating temperature.
  • the second catalyst preferably also comprises a carrier body and a catalytic coating for the total oxidation of hydrocarbons, preferably for the total oxidation of butane, propane or mixtures thereof.
  • the carrier body of the second catalyst is made of a ceramic material, which essentially does not sufficiently heat the carrier itself, but preferably only the coating, and therefore also cools faster when not in use.
  • the coating of the second catalyst may be identical to or different from that of the first catalyst, wherein z.
  • platinum, palladium and / or non-noble metal mixed oxides may be included.
  • the use of ceramic as a carrier material for the second catalyst is advantageous because it is depending on the design, in contrast to the first catalyst, partially unprotected in the frontal opening of the heating element and / or slides during assembly on the wall of the combustion chamber, Therefore, a good adhesion of the coating on the carrier body is necessary, which is given in the use of ceramic as a carrier material in an optimal manner. As a result, the risk of dissolving and the inhalation stream supplied components of the coating is largely eliminated and increases the stability of the second catalyst considerably.
  • the dimensioning of the first and second catalyst depends essentially on the usable surface area of the catalyst coating and on the intended flow rate of gas or gas / air mixture. The more porous the coated carrier, the smaller the required volume and the more compact the burner and thus the device. The dimensioning of catalysts in terms of clean combustion is known per se.
  • the regulator valve is a hollow needle valve with peripheral inlet and frontal outlet, wherein the hollow needle is axially movable and includes means for generating a restoring force.
  • the hollow needle valve also serves as the main valve. It is preferably by axial displacement of the hollow needle from a closed state, in a minimally open, an open and all states between minimally open and open state displaceable.
  • This piston is mouthpiece side acted upon by suction at the mouthpiece by a negative pressure and is preferably in contact on the opposite side with atmospheric pressure.
  • the heating device or the heating element described here can be connected to a mouthpiece containing an active and / or aroma depot.
  • the exhaust gases of the burner are, partially or completely, possibly mixed with ambient air, passed through the mouthpiece to evaporate through the thus generated hot air, or -gases the substances contained in an active and / or flavoring depot, z. B. in order to inhale it as an aerosol.
  • For releasably connecting or pushing the mouthpiece of the heating element mouthpiece side is preferably provided with a cylindrical flange.
  • This cylindrical flange may advantageously be provided with one or more ramps, which are pushed by sliding a mouthpiece radially inward, which move the piston and the associated hollow needle counter to a restoring force in the axial direction so far that the hollow needle valve from the closed in the minimal open state is added, and the closed state is released only by pulling the mouthpiece.
  • the combustion chamber preferably has at least one axial outlet opening through which the burner can be ignited from the outside.
  • the device is preferably designed such that the combustion chamber contains one or more preferably coaxially arranged openings in the region of the second catalyst.
  • the openings are preferably arranged such that the surfaces of the openings projected along their axes do not impinge directly on the surface of the catalyst surfaces, so that they leave no radiant energy of the catalysts, so that the housing sleeve even at full load in the front burner side area (corresponding to a proper use for Inhalation, ie essentially that of a normal smoking cycle) is not heated substantially above 70 ° C, preferably not above 60 ° C, more preferably not above 50 ° C.
  • a hot gas collector is arranged coaxially around the combustion chamber, which is connected to the combustion chamber via the coaxial opening (s) and is separated from the housing sleeve by an air gap.
  • the hot gas collector is designed such that it communicates with the mouthpiece side hot air outlets via a heat pipe in connection, wherein the heat pipe is separated by an air gap of the housing sleeve and the other components.
