Definitions

  • the invention relates to filter cartridges for smoking utensils, and cigarette or cigar tips, in which a filter core is integrated.
  • filter cartridges consist, for example, of absorbent material, those which contain chemicals of various types and compositions and others which consist of hollow cylinders which are pushed into one another. With some filter cartridges of this type, the smoke is led through narrow smoke passages in order to separate out tar and nicotine particles.
  • the object of the present invention is to implement a filter for the stated purpose, in which the criteria mentioned by Dr. Wenusch are not met on their own, but are also surpassed by further improvements and are so small that the filter does not exceed the customary dimensions .
  • the filter is composed of a filter core and a filter jacket, and the filter core is provided with radial, preferably rectangular incisions which, together with the inner wall of the filter jacket, form a long circumferential smoke channel.
  • a core length of 40 mm for example, a channel length of up to 500 mm can be easily implemented.
  • the smoke channel is such that the smoke during the passage of the filter describes a Kreisformige web to the end, either continuously or repeatedly alternately changed from the beginning of its direction by 340 0 and 180 0th As a result, the smoke is continuously rotated, which causes an intensive swirling of the smoke, which, together with the rectangular cross-section of the smoke duct, is about 20% larger than that of a round, straight smoke duct, not only for better tar deposition. and nicotine particles on the walls of the smoke channel, but also molecules of the gas phase, such as the highly toxic carbon monoxide, are bound and deposited.
  • small ventilation openings can be provided at the end of the filter.
  • means can be attached to the end of the filter jacket, which bring about additional cleaning.
  • the filter shown in longitudinal section in FIG. 1 and the cigarette holder according to FIG. 14 consist of a filter core 1 with a spiral cut 2 and the filter jacket 3, which according to FIG. 14 consists of a cigarette holder.
  • the tobacco smoke has free access from the Ziga - .retteneinsteckseite 4 to the - formed by the filter core incision 2 and filter jacket 3 - smoke channel 2.
  • the tobacco smoke continuously changes its direction through the spiral smoke channel 2 and at the end leaves the smoke outlet 6 through a narrow nozzle opening 5 Due to the fact that the smoke is not directed straight ahead but in a circle, no column of smoke can form which experience has shown would only touch the outside of the duct wall.
  • the filter shown in longitudinal section in FIG. 3 and in partial sections in FIGS. 6 to 9 consists of a filter core with radial parallel incisions 9 and the filter jacket 13.
  • the core incisions 9 between each two adjacent "lamellae" 10 are on one side of the axis 11 starting with a web 12 Fig. 7-9 closed to the lamella edge and together with the filter jacket 13 form the smoke channel.
  • smoke passages 14, 15 and 18, which can be of different shape and size, are arranged alternately to the right and left of the webs.
  • the mode of operation of this filter according to FIG. 3 is explained below with reference to FIGS. 6-9; the core incisions 9 form the smoke channel with the filter jacket 13.
  • the smoke is gnawed through the smoke passage 18 in the upper lamella 16, FIGS. 3 and 6, and comes directly into the intermediate space 9 formed by the two upper lamellae 10 and 16, where it is rotated about 340 ° to the left in a circle and known with a deflection of 180 ° through the smoke passage 14 Fig. 7 in the next space and will now turning to the right, in circles , through the smoke outlet 15 Fig.8 one step down again to be led. These processes are repeated until the smoke leaves the smoke duct through the smoke passage 18, FIGS. 3 and 9,
  • the smoke at the filter end is subjected to a final cleaning with the nozzle 5 or, according to FIG. 10, with a granulate filling 21 as an additional filter.
  • the carbon monoxide can also be detoxified even more by means of fresh air openings 7, FIGS. 11 and 14 provided at the end of the filter.
  • the filter with the laser core according to FIG. 3 described above results in better detoxification of the tobacco smoke than the filter with the spiral from Change of Smoke intensifies,
