As shown in Figure 2, flow governor part 4 comprises the first noumenon part 7 and the second body part 10 of rotatably installing with respect to described the first noumenon part 7, and described the first noumenon part 7 comprises the mouth end pieces 8 that is fixed on appropriate location with respect to intermediate member 9.Tubulose is arranged and be substantially to described parts 8,9,10 coaxially, and preferably by molded plastics, made.Described parts 8,9,10 can for example have the diameter of about 7.8mm.
When flow governor part 4 is arranged in cigarette as shown in Figure 1, the second body part 10 is attached to tobacco rods 2 by tipping paper 6, and the first noumenon part 7 rotates freely with respect to described bar 2 simultaneously.As will be described in more detail, body part 7,10 has the first position of rotation (shown in Fig. 3), and in the first position of rotation, smog can longitudinally pass flow governor part towards the mouth end of cigarette 1.Body part 7,10 can rotate to the second place (shown in Fig. 4) from primary importance, and in the second place, smog stream is reversed guiding through being positioned at flavorant in intermediate body member parts 9 and being rebooted and thus through device 4 towards the mouth end of cigarette 1 subsequently.In this way, the smog pumping out from cigarette 1 can optionally add flavouring agent by making body part 7,10 be positioned at the second place with respect to the first noumenon part 7 rotation the second body parts 10 (or vice versa).Compare with the smog flow path shown in Fig. 3, along the Route guiding smog shown in Fig. 4, fail to be convened for lack of a quorum and increase the pressure drop through filter cell 3, thereby provide simultaneously, add the smog of flavouring agent and increased draw resistance.
Go to now the more detailed description of flow control device 4, as shown in Fig. 2,3 and 4, body part 8,9,10 comprises the passage 11,12,13,14 with the cross section that is substantially kidney shape, and described passage 11,12,13,14 allows smog in the first and second positions, to pass parts 8,9,10.Passage 11,12,13,14 can for example each have about 6.7mm
2cross-sectional area.
Fig. 3 shows the cross-sectional view of device 4, and wherein the second body part 10 is positioned at primary importance with respect to the first noumenon part 7.As shown in the figure, the access road 11 in the second body part 10 is aimed at passage 12 in intermediate member 9 and the passage 13 in mouth end pieces 8, limit thus through device 4 without flavorant smog flow path 11,12,13.
As shown in the figure, intermediate member 9 has the impermeable interior wall 15,16 of smog limiting containing the chamber 17 of flavorant.When body part 7,10 is positioned at primary importance, wall 15,16 prevents that smog from entering the chamber 17 containing flavorant.While entering the second place shown in Fig. 4 when body part 10 Rotate 180 degree from primary importance, passage 11 in the second body part 10 is aimed at the passage 14 in intermediate body member part 9, and described passage 14 is aimed at the smog guiding recess 18 forming in mouth end pieces 8 again.Smog guiding recess 18 does not pass completely through parts 8 but is configured to smog is guided to as the chamber 17 containing flavorant from passage 14.As shown in Figure 4, smog guiding recess 18 causes smog to reflux, and makes smog along flowing through flavorant chamber 17 with the direction of the mobile opposite direction through passage 14 of smog.Second portion 10 comprises similarly but towards the smog guiding recess 19 of opposition side, this smog guiding recess 19 is configured to smog is directed in the passage 12 intermediate member 9 from the chamber 17 containing flavorant, make thus the direction of smog stream reverse, smog is flowed through the mouth end of passage 12,13 and outflow device 4 along the direction identical with passing passage 14.In this way, at second place smog flow path 11,14,18,17,19,12,13, be restricted to through device 4.Smog through this path is added flavouring agent by the flavorant in chamber 17 and walks along the longer path of smog flow path than primary importance, thereby has increased draw resistance.Alternatively, passage 11,12,13,14 and recess 18,19 are full of the cellulose acetate tow of the material of smoke permeable-for example, thereby be further increased in the first and second positions through the draw resistance of device 4, because fume path is longer, this resistance is larger for the second place.
Advantageously, because longer to the diffusion path of device outlet, come the flavouring agent of the chamber 17 of self-contained flavouring agent can not shift out device 4.In this way, flavouring agent will substantially can not move into cigarette 1 or move to other cigarettes in Cigarette pack from filter cell 3, and this movement may not liked by consumer.
Although be that body part 10 is with respect to body part 7 rotations to the declarative description of Fig. 3 and 4 above, but should be understood that, consumer can be by remaining on the hand of a use in the first or second body part 7,10 appropriate location and turning another body part or alternatively rotate between the first and second positions by rotating in opposite direction body part 7,10 with another hand-screw.In fact, consumer may prefer tobacco rods 2 to remain on appropriate location and rotate mouth end body part 7, but not maintains part 7 and rotate tobacco rods 2.
Chamber 17 containing flavorant illustrates in greater detail in Fig. 5 a, 5b, 5c and 5d.As shown in the figure, the both sides of chamber 17 are provided with and keep grid 20,21, and this maintenance grid construction becomes to allow smog enter chamber 17 but prevent may drop out for the flavorant of granular form in chamber 17.As shown in Figure 5 c, intermediate member 9 has two pairs of locating holes 22, a pair of each for grid 20,21, thus and keep grid to be provided with being contained in the alignment pin 23 that in locating hole 22, described maintenance grid is fixed on to appropriate location.Chamber 17 containing flavorant can have the chamber size of about 0.03cc and keep grid 20,21 can be suitable for providing about 3.5mm
2draught area.The less large young pathbreaker in smog aperture cause through the more high pressure drop of device 24 and thus the large I in described aperture be configured to realize the pressure drop of expectation.
Fig. 6 shows alternative flow governor part 24.As shown in the figure, flow governor part 24 comprises that can be formed by molded plastics overall is the first and second body parts 25,26 of tubulose.As shown in the figure, the first noumenon part 25 comprise two integrally formed be totally the tubular element 27,28 of cylindricality, described member 27 has the diameter that is less than member 28.The second body part 26 has the first and second ways 29,30 on its contrary side, thereby limit, is configured to the bore hole 31 that holds slidably member 27.In this way, thus the first noumenon part 25 grooves receive in the second body part 26 and can rotate therein.The length of the second body part 26 can be for example 6mm, and the overall length of device 24 can be 11mm.The diameter of device 24 can be 6.8mm.
As shown in the figure, ways 29,30 further limits the smoke path 32 through body part 26, when the second body part does not have groove to receive appropriate location described in smoke path 32 to bore hole 31, open.Consult Fig. 7 and 8, there is shown cutaway view, the second body part 26 has the antetheca 33 that comprises smog aperture 34, and smog aperture 34 allows smog to enter smoke path 32.Smog aperture 34 for example can provide about 5.8mm
2inlet area.

2total draught area.
As shown in the figure, annular wall 37 has peripheral part 42, and described peripheral part 42 has a plurality of smog aperture 43, and the remainder 44 of annular wall 37 forms the barrier of impermeable smog simultaneously.As shown in Figure 7, in primary importance, the impermeable part 44 of wall 37 limits the inwall of smoke path 32, thereby prevents that smog from entering the chamber 39 containing flavorant.The first noumenon part 25 Rotate 180 degree, to the second place shown in Fig. 8, can be alignd the smog aperture 43 in peripheral part 42 with passage 32, thereby provide the inwall of permeable smog for passage 32.In this way, smog can flow through aperture 43 and enter chamber 39 from passage 32.Preferably, aperture 43 provides about 8mm
2total draught area.
As shown in Figure 8, in the second place, passage 32 is not aimed at passage 35, thereby by the annular wall 36 of member 28, blocks the end of described passage 32.Thus, in the second place, unique path that smog can be walked is by aperture 43.
Arrow 45 in Fig. 8 shows the path of the device 24 of passage of smoke in the second place.As shown in the figure, smog enters device 24 and admission passage 32 by smog aperture 34.Smog becomes horizontal direction pass smog aperture 43 and enter the chamber 39 containing flavorant along the longitudinal axis with device 24 subsequently.Smog is subsequently longitudinally through the chamber 39 containing flavorant that has wherein added flavouring agent.Add the smog of flavouring agent to pass subsequently and flow out the aperture 41 in end cap 40.
Because smog is along laterally entering chamber 39, thus smog and particle thereon interactional surface area be only subject to the size restrictions in smoke permeable region 42, rather than limited by the cross-sectional area of device 24 as the mobile situation of longitudinal smog.Therefore, compare with the situation that longitudinal smog is mobile, can increase interactional surface area and strengthen the local flavor transmitting.
In addition, smog aperture 43 and 41 large I are set to provide in the second place draw resistance of expectation.Thus, for example, thereby smog aperture 43 can be made into enough little making, through the pressure drop of the device 24 in the first and second positions, there is perceptible difference, and then provide different smoking to experience according to the selected consumer that is oriented.
Aperture 41 in end cap 40 can be suitable for the remainder that allows flavouring agent to move to cigarette 1 and may move to other cigarettes in Cigarette pack, thereby before smoking-smell of flavouring agent is for example provided for cigarette providing when opening cigarette.As mentioned above, although may not expect that in some cases so some consumer cigarette the providing for them before smoking may be provided and add the smell of flavouring agent and this right to choose to provide by device 24.
Advantageously, the first noumenon part 25, the second body part 26 and end cap 40 are made by molded plastics and can be used known injection moulding technology to manufacture.With hand or with machine, part 25,26,40 grooves to be received to the assembly ware 24 of coming together be very easily.
