Description
Mundstück B bandelt es sich grundsätzlich um ein Menge von Luft aus der Umgebung über die Periora-Rohr 12, das das die Füllung enthaltende Elemente tionen 21 in der Seitenwand in die Kammer 29 hinträgt, das gemäß Fig. 1 und 2 von dem Element B eingesaugt. In der Kammer 20 mischt sich der aus längs einer kurzen Strecke überlappt wird, wobei die dem Element A austretende Rauch mit der über die Berührungsflächen der Umhüllung 10 und des geroll- 5 Perforationen 21 angesaugten Luft.

In the chamber 20, the overlap is mixed along a short distance, the smoke emerging from the element A with the air sucked in via the contact surfaces of the envelope 10 and the rolled perforations 21. The resistance, th pipe 12 with the help of an adhesive or one which is opposed to the smoke-air mixture when passing through the binding agent with a sealing effect central opening 14, leads to are connected. a reduction in the flow velocity.

Then the smoke-air mixture spreads, must flow if the smoker with his mouth it is distributed over the entire cross-sectional area and creates a train. In the embodiment according to FIG. 20, all parts of the filter element 17 and finally arrive at FIG. 1 to 3 is the plate or disc in a lent in the smoker's mouth,
stood arranged by the filter material. Randab- The flow speed of the smoke at the sections 15 and 16 of the plate or disc keep the draw on the lit cigarette is regulated by the disc at a distance from the adjacent flow speed, which the smoke exposed filter materials or filter elements 17 and 25 when passing through Opening 14 in the element B er-18 so that free spaces 19 and 20 are rich in the mouthpiece. As the flow rate of the through are present. The edge 16, which reduces the size of the space 20 to the smoke sucked in through the element B , has such an axial length that the entire smoke slows down so that it delimits a chamber into which air from the process is drawn. This lower flow velocity of the environment through overlapping perforations 30 remains from the beginning of the smoking process when the lighting or fine openings 21 in the walls can be sucked in by the cigarette having its full length, which is through the pipe 12 and the to reach the smallest length on End of the edge 16 are formed. The perforations 21 are obtained in the smoking process. Arranged as a result of the regulation or shape of a ring and by throttling through the central opening, the flow level in front of the filter element 18 is separated. The size of the smoke flow rate during the central opening 14 as well as the size and number of smoking processes practically on a uniform perforation 21 are selected in such a way that a drug value is maintained. This uniformity of the puffing effect is exerted in order to achieve the desired uniform velocity of the smoke, that a moderate mixing ratio between the smoke and the air is to be achieved during the entire smoking process; For example, the open smoke-air mixture ratio can be maintained 14 have a diameter of about 1 mm.
