Diluent holds in the cooling chamber 40 in regional downstream that material 35 can replacedly be placed on high FE material 30.The additional areas of diluent can be positioned at the further downstream of filter part 20.Circulation and cooling space when the cooling chamber 40 shown in accompanying drawing 1 provides smog to transmit downstream.The length of cooling chamber 40 can be between 10 to 30mm.
The further downstream of cooling chamber 40 is zones of low FE material 45.Low FE material 45 can be made with the cellulose acetate line, although other low FE filtering materials known in the art can be used.Low FE material 45 can form stopper, and when smog passes through, it absorbs smoke composition.The length in the zone of low FE material 45 can be between 10 to 30mm.
Mouth end filter part 55 is placed on mouth end 60 places of smoking article 10.The length of mouth end filter part can be between 5 to 15mm.Mouth end filter part 55 can be made by low FE filtering material stopper, wherein there is no sorbent material.Mouth end filter part 55 has stopped that sorbent material 50 enters and contact user's mouth.Although do not illustrate in accompanying drawing 1, spices can be included in mouth end filter part 55.This makes it can have the effect of any changing odor that counteracting may cause by sorbent material 50.
Tipping paper 25 is provided with space 65 along its long limit, and it allows Air infitration filter part 20 and some smoke compositions to penetrate filter part 20.
An alternative embodiment of cigarette 10 as shown in Figure 2.Filter part 20 is basic identical with the filter part 20 shown in accompanying drawing 1.Extend along the longitudinal axis of tobacco rods 15 in hole 70.Hole 70 provides the approach of smog from charcoal 75 high FE filterability material 30 transmission downstream of burning.Hole 70 can have the diameter between 1 to 3mm.Also can use a plurality of holes basically parallel to each other.Hole 70 helps heat to 20 transmission of filter part.
With reference to accompanying drawing 1, describe, because composite material can help the shape of retaining hole, the tobacco by extruding or compression and carbon mix form tobacco rods 15 can also make the formation in hole 70 easier.For example guar gum or sticky stuff cut tobacco and also can make the shape that helps retaining hole to add adhesive.
Be similar to the cigarette 10 that still there is modification filter part 20 shown in accompanying drawing 2 as shown in Figure 3.Tipping paper 25 does not arrange space, example space 65 as shown in Figure 2.Air is through tipping paper 25 and 27 infiltrations of filter stick formation paper of natural porous.Similarly, some compositions of smog can penetrate filter part 20.
Be similar to shown in accompanying drawing 1 but comprise replaceable setting filter part 20 cigarette 10 as shown in Figure 4.In this embodiment, sorbent material 50 has been comprised in cooling chamber 40, for example, to fill completely or substantially to be full of the small particles form of cooling chamber chamber.
When the cigarette 10 shown in accompanying drawing 1 is lighted by the user, tobacco rods 15 and the position of being lighted around the wrapping paper 26 of tobacco rods 15 have formed charcoal 75.Formed pressure differential when the user aspirates by mouth end filter part 55, therefore formed the smog air-flow, it moves to filter part 20.
The smog air-flow is comprised of Multiple components, and each in them exists with vapor phase and/or Particle Phase.The amount of each smoke composition existed mutually with each depends on the temperature of smog.The ratio that is present in the particle smoke composition in vapor phase raises and increases with temperature.
When smog moves towards filter part 20 downstream by tobacco rods 15, the temperature of along with it, from charcoal 75, far moving smog reduces.The reduction of smog temperature is because some factors reduce, for example mobile variation of the smog in downstream.Use the wrapping paper flow of low air permeability of short and thin tobacco rods or the groove by the low flow resistance in tobacco or hole and parcel tobacco rods influential.It is also important factor that other factor for example adopts the thermal mass of heat conducting material and minimizing tobacco rods.
When smog arrives high FE material 30 regional, the composition with the Particle Phase transmission of vast scale will be removed from the smog air-flow.The composition of Particle Phase is compared and is had higher boiling point with the composition of vapor phase transmission.Vapor phase composition quite in a small amount will inevitably be removed by high FE material 30 from the smog air-flow.Yet, when more smog is sucked by filter part 20 subsequently, the part of these compositions can be by elution from high FE filterability material 30.
The smog air-flow holds material 35 by diluent, and it dilutes smog by adding more multicomponent in smog aerosol.As mentioned above, diluent holds material 35 and can be placed in the zone of high FE material 30 or in cooling chamber 40.
Be cooled to lower temperature at the interior smog of cooling chamber 40.Before multiple when smog is cooling, the composition of vapor phase condenses into Particle Phase.
