Definitions
- the invention relates to a smoking article with a mouthpiece for sucking a particle-laden gas, wherein the particle-laden gas is heated.
- the invention also relates to a method for cooling a heated particle-laden gas in a smoking article.
- a smoking article typically a cigarette, includes at least one column of tobacco wrapped by a wrapping material.
- smoking articles are also equipped with filters to influence the type and amount of substances in the smoke.
- filters usually made of cellulose acetate or paper, can reduce the particulate matter of the smoke. Filters may also contain other substances, such as activated carbon or flavorings.
- a liquid or liquid contained in a tank are supplied to an evaporator in which they are evaporated.
- the vapor is then directed via a flow channel to an outlet opening in a mouthpiece and can be inhaled by the user.
- support materials are generally used. These may be formed, for example, from glass fibers, cotton material formed like a cotton, stainless steel sieves or the like.
- so-called "heat not burn products” are becoming increasingly popular.
- the tobacco is not burned, as in a conventional cigarette, but heated only with an electronic accessory. This prevents the formation of harmful substances that would be produced by the thermal decomposition of the tobacco when it is burned.
- the present invention is therefore based on the object of specifying a smoking article and a method for cooling a heated particle-laden gas, in which the temperature of the user of a smoking article recorded gas, aerosol or vapor can be reduced.
- At least one cooling device is included for cooling the particle-laden gas, that the particle-laden gas flows through the cooling device during suction, that the cooling device comprises a cooling material that cooling by the Cooling device is realized by means of an endothermic process of the cooling material and that the endothermic process is activated by the heated particle-laden gas.
- a particle-laden gas is generally understood to mean gases which contain a further constituent, in particular also aerosols with solid and / or liquid components as well as steam, mist and smoke.
- a cooling device is additionally provided, through which the sucked air and, for example, tobacco smoke must flow before the gas stream, ie the mixture of the sucked air and the tobacco smoke, or wet steam of an e-cigarette, hereinafter generally particle-loaded gas called, can escape from the mouthpiece.
- the cooling The direction comprises a cooling material, on which the particle-laden gas can flow past and / or flow through. The particle-laden gas is heated due to evaporation or a combustion process. This amount of heat serves to activate an endothermic process in the cooling material.
- the nature of the endothermic process depends on the nature and nature of the cooling material. In an advantageous embodiment of the invention it is therefore provided that the endothermic process is realized by means of desorption. It has proven to be advantageous to use substances as a cooling material that can deliver absorbed water to the environment. Silica and / or zeolite can therefore be used as the coolant.
- the endothermic process is realized by means of melting and / or vaporization of the cooling material. Even when melting or evaporating energy is introduced into the cooling material.
- the required melting or enthalpy of vaporization ie the amount of energy required to melt a substance sample at its melting point at constant pressure or to vaporize at its boiling point, ie to convert it from solid to liquid or liquid to gaseous state , which is introduced from the outside, ensures that the particle-laden gas cools before it exits the mouthpiece.
- Suitable cooling materials are both inorganic and organic substances.
- Another additional or alternative possibility to design the endothermic process provides that the endothermic process is realized by releasing water of crystallization of an inorganic salt.
- an inorganic salt As a coolant Therefore, in particular Glauber's salt, ie sodium sulfate hydrate, and Epsom salt, ie magnesium sulfate hydrate, can be used.
- Sodium sulfate is sometimes used in the tobacco industry to inhibit the smelling of casing material so that the wrapping material does not burn off too quickly.
- These and correspondingly similar inorganic salts are present under normal conditions as a crystalline solid.
- the water of crystallization or water of hydration is bound by the crystalline lattice structure within the solid.
- the water molecules in these salts are coordinated to ions or through hydrogen bonds. Energy is needed to release the water of crystallization. The energy is provided by the heated particle-laden gas. In this process, the particle-laden gas thus cools down before it can escape from the mouthpiece.
- the cooling device can be arranged at different points of the smoking article.
- a filter element is included, that the filter element is arranged in the flow direction of the particle-laden gas in front of the mouthpiece and that the filter element comprises the cooling device.
- the arrangement of the cooling device in the filter element of the smoking article if it is, for example, a conventional cigarette, be designed almost without change.
- a cigarette with a filter element already has structures in which the cooling device can be introduced with the cooling material.
- the cooling device has an elongate carrier material and that the elongated carrier material comprises the cooling material.
- the carrier material can also simultaneously form the cooling device.
- the carrier material is folded several times. In this way, the largest possible surface area is created at which the particle-laden gas passes or through which the particle-laden gas flows.
- the carrier material may consist of a thin material so that as many folds and a correspondingly large surface can be realized without disproportionately increasing the dimensions of the smoking article.
- the folds NEN also be designed such that the carrier material is rolled or cut and placed in parts one above the other.
- the cooling material may be previously printed or painted on the substrate. In this way, the largest possible application of the cooling material is possible, whereby the particle-laden gas can be cooled better.
- the carrier material can be introduced into the smoking article in such a way that the folds are arranged transversely to the flow direction of the particle-laden gas. In this way, the particle-laden gas must flow through the carrier material.
- the carrier material must therefore be permeable to air.
- the carrier material may also be incorporated in the smoking article such that the convolutions are arranged in the direction of flow of the particle-laden gas. In this way, the carrier material is flowed through by the particle-laden gas, but does not flow through it. Air permeability of the carrier material is therefore not absolutely necessary in this embodiment.
- the carrier material is simultaneously part of the cooling device and the filter element.
- filter material for filtering the particle-laden gas can additionally be introduced into the interstices of the folds. It is also conceivable that the carrier material is already made of filter material.
- the alternative arrangements of the folds of the carrier material in the smoking article can also be realized simultaneously.
- the smoking article then has a section in which the folds of the carrier material are aligned in the direction of flow of the particle-laden gas and a section in which the folds are oriented transversely to the flow direction of the particle-laden gas.
- the cooling material can be arranged on the carrier material in different ways.
- the cooling material may be applied to the surface of the carrier material. It is advisable that the cooling material is printed or painted on. Thus, one is possible large-area application of the cooling material possible, whereby the particle-laden gas can be cooled better.
- the cooling material is introduced into the carrier material.
- the cooling material can already be incorporated in the paper pulp during the production of the carrier material, which can be produced, for example, from paper.
- the cooling material may be introduced into the cooling device in small particles.
- the small particles can be introduced into the intermediate spaces of the folds of the carrier material in order to further improve the effect of the cooling device.
- the cooling material can also be scattered into the filter material. The filter element then performs a dual function, since it filters toxic substances from the particle-laden gas and at the same time ensures the cooling of the particle-laden gas.
- the cooling device may also be provided directly in the tobacco mixture, the small particles then being introduced into the tobacco mixture.
- the size of the particles also depends on the nature of the cooling material. In general, all particle size distributions that do not disproportionately increase the dimensions of the smoking article are conceivable. Disproportionate in this context means a strong deviation from the dimensions of a conventional smoking article.
- a further embodiment of the inventive smoking article provides that the cooling device is arranged as a separate segment in the flow direction of the particle-laden gas in front of the mouthpiece.
- the separate segment may have a variety of shapes. By way of example, a preferred cylindrical shape is described, to which the invention should not be limited.
- Conventional smoking articles are usually designed substantially cylindrical.
- the separate segment can also be arranged upstream of a possible filter in the flow direction of the particle-laden gas.
- the cooling device as a separate segment can for example consist entirely of the cooling material.
- the separate segment has a kind of housing, so that the cooling material encapsulated as porous material or may be present as a powder in the housing.
- the housing has an inlet opening and an outlet opening for the particle-laden gas, through which it flows through the user due to the suction through the mouthpiece.
- the cooling device may also be optionally mountable in or on the smoking article. In this way, a user has the option of only cooling the particle-laden gas if he considers it necessary.
- the above object is achieved in a method described above for cooling a heated particle-laden gas in a smoking article having the features of claim 12 characterized in that the particle-laden gas is passed through a cooling device during suction, that the cooling device comprises a cooling material that the cooling is realized by the cooling device by means of an endothermic process of the cooling material and that the endothermic process is activated by the heated particle-laden gas.
- the cooling material is selectable such that various endothermic processes can be initiated.
- the endothermic process will be realized by means of desorption. Another possibility is that the endothermic process is realized by melting the cooling material. In addition, it is possible that the endothermic process is realized by releasing water of crystallization of an inorganic salt.

- FIG. 2 is a schematic sectional view of a smoking article with a cooling device
- Fig. 3 is a schematic representation of a cooling device for a smoking article
- FIG. 4 is a schematic sectional view of an encapsulated cooling device in a smoking article.
- FIG. 1 shows a smoking article 1 with a mouthpiece 2, through which a particle-laden gas 3 can flow on the mouthpiece 2 during suction.
- the smoking article 1 in the form of a cigarette has a cooling device 4, wherein the cooling device 4 comprises a cooling material 5.
- the cooling device 4 is arranged in the flow direction of the particle-laden gas 3 (represented by the arrows) in front of a filter element 6.
- a carrier material 7 is arranged in the interior of the cooling device 4 (cf., FIG. 3), on which particles 8 of the cooling material 5 are interspersed in the intermediate spaces of the folded carrier material 7.
- the cooling device 4 is designed as a separate segment 9 in the cylindrical arrangement of the cigarette.
- the filter element 6 is adjacent to the mouthpiece 2. Adjacent to the other end is a wrapping material 10 which encloses a tobacco rod 11. If the smoking article 1 is lit at the end of the tobacco rod 11, the tobacco burns with the wrapping material 10 at about 800 ° C and develops the tobacco smoke, which can be sucked through the mouthpiece 2 by the smoking article 1. For the user, the smoke is not so hot, but still has a high temperature, which is perceived as unpleasant for the user.
- the tobacco smoke or generally the particle-laden gas 3 flows through the smoking article 1 and, accordingly, through the cooling device 4 in which the cooling material 5 is arranged. The high temperature of the particle-laden gas 3 is sufficient to activate an endothermic process of the cooling material 5.
- the cooling device 5 is formed by a multiply folded carrier material 7.
- the folds 12 are aligned transversely to the flow direction of the particle-laden gas 3.
- the carrier germaterial 7 is designed to be permeable to air, so that the suction can be easily realized by the user.
- the carrier material 7 is coated with the cooling material 5.
- the cooling material 5 was previously printed on the carrier material 7 during production.
- the cooling device 4 simultaneously represents the filter element 6, wherein between the folds 12 of the carrier material 7, filter material is interspersed to filter out pollutants of the particle-laden gas 3, which is formed by the burning tobacco rod 11.
- Fig. 3 shows a cooling device 4 for a smoking article 1 in a sectional view. Shown is a carrier material 7 which is folded several times. The carrier material 7 is coated with the cooling material 5 by prior printing of the carrier material 7 with the cooling material 5. In addition, small particles 8 of the cooling material 5 are arranged between the folds 12 of the carrier material 7 in order to maximize the cooling effect of the cooling device 4.
- the carrier material 7 of the cooling device 4 is not made of an air-permeable material.
- the folds 12 of the carrier material 7 must therefore be aligned in a smoking article 1 in the flow direction of the particle-laden gas 3, so that the particle-laden gas 3 can easily flow through the cooling device 4 when the user aspirates.
- the surface of the carrier material 7 is merely flowed through, but not flowed through.
- the cooling device 4 shows a detail of a smoking article 1 in a sectional view with a separate cooling device 4.
- the cooling device 4 has a housing 13 in which the cooling material 5 is arranged in small porous particles 8.
- the housing 13 serves to enclose the cooling material 5 so that it can not disperse in the smoking article 1.
- the housing 13 of the cooling device 4 has a perforated inlet opening 14 for entering particle-laden gas 3 and a perforated outlet opening 15.
- the particle-laden gas 3 can flow through the inlet opening 14 and through the outlet opening 15 and thereby comes into contact with the cooling material 5, whereby the cooling of the particle-laden gas 3 is activated due to the high temperature of the particle-laden gas.
- the cooling device 4 as a separate segment 9 can be removed from the smoking article 1 and used as needed. In this way, a user can decide for himself, when he considers it useful to cool the emerging from the mouthpiece 2 particle-laden gas 3.
