Definitions

  • the invention relates to a filter material for reducing Pollutants in tobacco smoke according to the preamble of the claim 1.
  • tobacco smoke When tobacco burns, tobacco smoke is produced, an aerosol that consists of a gas phase and a condensate phase.
  • the gas phase of tobacco smoke is relatively simple. In addition to nitrogen, oxygen, carbon dioxide and hydrogen and noble gases also contain the toxic substances carbon monoxide (approx. 4.2%), hydrocyanic acid (approx. 0.16%), ammonia (approx. 0.03 %), Nitrogen oxides (approx. 0.02%) and traces of hydrogen sulfide.
  • the main part of the ingredients can be found in the condensate phase ("tar"), including that Tobacco smoke aroma forming flavors and fragrances.
  • Filter cigarettes, filter cigars and filter cigarillos as well Developed cigarette and cigar tips and tobacco pipes, in the mouthpiece of filter materials a part of the nicotine and should remove the tar substances without doing essential Retain flavors.
  • These filter materials consist of cellulose, cellulose acetates, polyethylene, Crepe or paper or activated carbon.
  • silicate-containing minerals in particular Clay, kaolin and feldspar, as an adsorbent for tobacco filters used.
  • the disadvantage is that the mentioned Filter materials according to the published application of adherent Ion by treatment with distilled water or Acids, or freed by electrolysis or electrodialysis need to be used.
  • Filter materials are also known which are a film form and from a binder such as methyl cellulose and a fine-fiber material, which is provided with adsorbents, consist. Activated carbon, silica gel and asbestos fibers are used as adsorbents or named polyethylene glycol.
  • This filter material has the advantage of applying selective acting Adsorbents to filter out certain pollutants in this Case mainly phenol.
  • a disadvantage is the use of proven carcinogenic asbestos fibers that most of the flavor and smell of the tobacco smoke aroma is filtered out.
  • DE-OS 15 17 298 mentions filter materials made from activated carbon grains with a largest diameter of 0.1 - 2 mm, the connected by a binder such as polyvinyl resin or polyethylene are. Again, it is disadvantageous that mainly Tar substances and thus also the taste and smell substances of tobacco smoke aroma, but not the toxic gas phase components such as carbon monoxide, hydrocyanic acid or ammonia become.
  • clays are mentioned as filter materials, those due to their gel and film-forming properties on substrates such as cellulose acetate fibers or paper can be applied.
  • substrates such as cellulose acetate fibers or paper
  • swellability Crucial for your application is their swellability. Therefore, they are mainly bentonites such as sodium montmorillonite and sodium attapulgite.
  • WO 96/07335 A1 describes a filter made of zeolite hydrophobic properties. This filter material can be used in combination with activated carbon or cellulose. Known are also filters that are either pure silica gel or contain pure activated carbon.
  • a disadvantage of the filter materials mentioned is that predominantly the tar substances in the condensate phase and less the toxic ones Gas phase substances are reduced. Because the tobacco smoke aroma forming flavors and fragrances as well are present in the condensate phase and together with the The use of the above-mentioned tar substances can be reduced Filter materials also have a negative impact on enjoyment of smoking. Another disadvantage is the short Filter effect duration of the filter materials mentioned. Just for filter materials in the tips of cigarettes and cigars as well as used in tobacco pipes and accordingly several times used is the degree of saturation and thus the loss the filter effect achieved relatively quickly, but externally hardly recognizable. In addition, some filter materials an increased pulling force can be used by the smoker, since that Filter material is so dense that tobacco smoke is not unhindered flows through the filter material.
  • the invention has for its object a filter material to create which besides improving the reduction the tar substances in the condensate phase if possible the complete elimination of the toxic substances in the gas phase causes without the tobacco smoke aroma and therefore the taste and smell are reduced. Further is to create a filter material that has a long filtering effect guaranteed, indicates the exhaustion of the filter and the Allows tobacco smoke to pass easily without increasing smoking Tractive force must be applied by the smoker.
  • the filter properties are thus reinforced by the additive Dimension of the individual components.
  • the composition can vary within certain limits.
  • a further development therefore provides that the filter material made of 20-45% marble, 35-60% activated carbon, 5-25% porous clay and / or 10-35% zeolite is composed.
  • the filter material can have a grain size between 0.1 and 2 mm diameter can be formed as granules.
  • the upper limit of the grain size is to ensure that a sufficient packing density and a sufficient degree of filling is achieved and also a mixture or at least partially Penetration of the filter materials can occur.
  • the lower limit should avoid excessive flow resistance and prevent very small particles from flowing get carried away and leave the filter.
  • the filter material in addition Cellulose fibers.
  • Cellulose fibers are already known as filter material and are suitable for reducing pollutants in the condensate phase.
  • the proportion of cellulose in the mixture is limited by that at higher proportions used by smokers tractive effort to smoke to be increased greatly and at the same time a declining tobacco taste and smell occurs.
  • Cellulose fibers have toxic substances in the gas phase even little influence.
  • Filter materials can be an improvement the reduction of tar substances in the condensate phase and the extensive elimination of toxic substances cause the gas phase without the tobacco smoke aroma and consequently, the taste and smell substances are reduced.
  • the cellulose fibers can be arranged in parallel be and the filter without changing direction in the longitudinal direction run through.
  • the individual cellulose fibers pass through the filter lengthways and repeatedly run back and forth in alternating directions.
  • cavities and directional channels are formed, so that in the filter Incoming tobacco smoke a longer way to exit of the filter, and more often with the filter materials comes into contact. There can therefore be more condensation and adsorption processes on the filter materials occur.
  • An advantageous embodiment is that in the form of granules Filter material on the individual cellulose fibers and / or in the channels formed by the cellulose fibers and / or cavities arranged.
  • the tobacco smoke is optimal with brought into contact with the filter material.
  • This dust can be, in particular when using cellulose fibers, easier in the filter bring in.
  • a further development provides that the filter material used porous clay is an expanded clay.
  • Expanded clay is thus traversed by air chambers and channels free of chemical residues. This is the surface of expanded clay for the adsorption of those present in tobacco smoke Pollutants are more suitable than those of other porous clays. The fine channels promote condensation and the pollutants it contains.
  • Expanded clay is also characterized by its low swellability and the associated dimensional stability, which makes the Filter duration is increased.
  • the large surface of Expanded clay ensures due to the large contact area between Filter material and tobacco smoke have a long filter effect.
  • the pulling force used by the smoker to smoke must, changes imperceptibly when using expanded clay. The smoke flows freely with good surface contact through the filter material.
  • a further development provides that a zeolite without fine fibers Structure is used. This prevents fine fibers come loose and are carried away by the current and be inhaled.
  • zeolite As a filter material, the Minimization of pollutants from the condensate phase and the gas phase reached.
  • a material is also used here, which differs due to its surface structure, which characterized by hollows and channels, significantly is suitable to filter out the pollutants of tobacco smoke and to have a minor influence on the tobacco smoke aroma.
  • zeolite over other silicate minerals like silica gel and clays is in the surface structure, the excellent hydration, ion exchange and Has molecular sieve properties. This improves in Comparison to the silicate-containing ones commercially available Filter materials reducing pollutants in the gas and condensate phase of tobacco smoke.
  • a further development provides that the filter material Substances unmixed side by side as a multi-phase system can be used.
  • the substances forming the filter material can also be used mixed together as a mixed phase system.
  • the filter materials without activation can be used.
  • the filter preferably comprises a consumption indicator.
  • the filter should be changed, as the adsorption properties of the filter material increase be low to effectively reduce the pollutants of tobacco smoke to minimize.
  • the consumption indicator are made of marble.
  • Cellulose has the same properties as marble. Also here a certain darkening shows the end of the pollutant absorption capacity on.
  • the consumption indicator is preferably in the direction of flow arranged behind the filter material. This arrangement has the Advantage that an optical change only begins when the filter material is almost used up. It occurs but then a very quick turnaround in the consumption indicator a, making the end of the filter's usability unique is signaled.
  • a further development provides that at least one venturi nozzle is arranged on or in the filter.
  • a surface is to be arranged directly behind the Venturi nozzle against which accelerated tobacco smoke flows.
  • venturi nozzle and / or the surface arranged behind the Venturi nozzle made of marble, activated carbon, clay, zeolite and / or cellulose consists.
  • the filters shown in the drawing each have a cylindrical housing 10 which can be inserted into a mouthpiece is or connected with a cigarette or can be manufactured.
  • the housing 10 is through a first 12 and second end piece 14 completed, which in the housing Fix 10 materials in place.
  • the end pieces 12, 14 are provided with openings 16 which pass through the tobacco smoke let the materials in the housing 10 but hold back.
  • the tobacco smoke passes through the filter in the drawing from left to right, so that first the filter zone 18 and then the indicator zone 20 is flowed through.
  • the filter shown in FIG. 1 is a Mixed phase system.
  • the filter materials are in the filter zone 18 arranged mixed.
  • the details are: Expanded clay, zeolite and activated carbon, which have the shape of granules exhibit.
  • the grain size can be between 0.1 mm and 2 mm be.
  • a mixed phase system is then particularly advantageous if a mechanical filling of the housing 10 with the Filter materials is carried out while doing a uniform Ratio of the proportions of the individual filter materials is desired.
  • the indicator zone is connected to the filter zone 18 20 with an indicator material 28, in this Case is filled with marble. This is also a Granules.
  • the filter shown in FIG. 2 is a Multiphase system. Filter materials are in the filter zone 18 arranged separately in several layers one after the other. In the illustrated embodiment is first a layer 26 with activated carbon, then a layer 24 with zeolite and then a layer 22 with expanded clay is arranged. Successors the three layers repeat themselves twice, however in different order. This version is advantageous for manual filling. Which is in the filter zone 18 subsequent indicator zone 20 corresponds to that from Fig. 1. Also in the representation of Fig. 2 are Filter materials in granular form available. The diameter range also corresponds to FIG. 1.
  • the filter shown in FIG. 3 is a Mixed phase system as in Fig. 1.
  • filter materials used are arranged in parallel, longitudinal cellulose fibers 30 into the filter housing 10 brought in.
  • the cellulose fibers 30 are suitable for their Filter effect, the tobacco smoke in the desired way through the filter. The tobacco smoke flows evenly through the filter and comes with the filter material in contact. With this arrangement, the cellulose fibers form 30 elongated channels, reducing flow resistance is kept very low.
  • the filter shown in FIG. 4 is a Multi-phase system as in Fig. 2.
  • filter materials used are individual in the longitudinal direction Cellulose fibers 30 introduced into the filter housing 10, the run back and forth several times changing direction.
  • the cellulose fibers form cavities and change direction Channels, which causes the inflowing tobacco smoke a longer Must travel until leaving the filter housing 10 and more often in contact with the filter materials is coming.
