The invention summation
At present, when carrying out strong suction, the filter passage in the cigarette stops up by twining the self-adhesion ligament around whole filtration zone prevent on the suction machine cigarette before. But in this technology, define following problem:
The self-adhesion ligament that uses may be by any company supply of making this product. Concrete prescription may be between company the uniformity of effect of different and various bands also may change.
Binding agent with upper use may not crookedly also may form until the leakage paths of passage with non-special use and mode at random with the filter tip bonding. The nonconforming dilution of cigarette flue dust can take place then.
Be used in this with on binding agent usually need pressure to be completed into seal. Filter substrate exerted pressure to make filter in when test distortion and therefore be close to the generation that affects the flue dust composition owing to the fiber of filter. This has introduced variable for analyzing aspiration procedure again
The binding agent that uses can have the volatile ingredient that sucks cigarette and pollute analyzed plume. In addition, aspiration procedure may be gone back the composition of releasing adhesive, and it can affect the flue dust composition. From the potential difference of various adhesive tape manufacturer Binder Composition will be at random and key element difficult to the appraisal introduce aspiration procedure.
The condensate band that uses also can be between manufacturer the different and therefore gas-permeable difference of various bands. If gas-permeable passes band, because some bands are designed to like this, the chocking-up degree of passage can change in uncertain mode.
Band usually applies with hand and adds, and is difficult to realize that reproducing of this band applied adds, and especially conventional suction test needs to twine a lot of cigarettes.
When twining cigarette with the end must can not be overlapping, otherwise when on the retainer that installs to mechanical aspirator, between retainer and cigarette little gap may appear, make air can enter the suction machine, the dilution plume also provides inconsistent result again.
When attempting to form perfect docking, usually can between the end of band, stay little gap, can produce again leakage paths and not reproducible reason.
Aperture in the band is difficult for being detected, and any hole in the plugging material can exert far reaching influence to the measurement result of flue dust composition.
In an embodiment of the present invention, elastomeric seal is used for stopping up the cigarette passage strongly to aspirate. The vacuum method of installing is used for guaranteeing that seal does not leak and aperture.
In an embodiment of the present invention, the seal of being made by silicone rubber, neoprene or any other suitable elasticity material is placed in the retainer or by mechanical interface with hand and is installed to retainer. The one or both ends of sealing member material are by anchor clamps or by suitably keeping the lip stretching to be installed on the retainer. Then by encapsulant being moved to the gap that removes on the pipe than relaxation state larger diameter between seal and the keeper. The process that removes retainer and seal gap not only stretches seal, and by using vacuum, guarantees that encapsulant does not have pin hole and leakage. Owing to by vacuum pulling seal, can and the slip that records be leaked sample with nothing by the suitable pressure scale monitoring natural leak rate of buying and compare. Departing from the expression encapsulant with desirable slip any lost efficacy and can not produce around the reproduced sealing of cigarette.
Seal is in case stretch, and cigarette is placed on the seal so that encapsulant covers end regions, or comprises the part of the end regions of passage. Discharge then vacuum, then elastomer element is loosened, and forms inclusion seal around filter.
As seen the seal that uses should be selected from and closely cooperate or the best diameter that is suitable for the filter diameter; But can design the suitable system that uses general retainer and the suitable seal diameter of certain limit.

Referring to Fig. 3, conventional cigarette retainer 70 comprises a plurality of labyrinths 58 that are used to clamp the cigarette 28 of having inserted retainer 70.Basically the blocking device that separates 72 of tubular form within it side comprise elastic sealing element 74.Seal 74 also is the tubulose that has lip in its top ends, and this lip is clamped around the end parcel of blocking device 72 and with it.Blocking device 72 is provided with exhaust port 76, and this port 76 is connected to vavuum pump 35, and mode is identical with above-mentioned reference first and second embodiment description.Perhaps, blocking device 72 off line before being installed on the standard retainer is installed on the cigarette in separate device, and mode is identical with the 4th embodiment described below.
The 4th embodiment
In the 4th embodiment, the plug for seal part is being installed on the cigarette of test in the custom-designed separate device of this purpose.The position of passage and the degree of perforation are known, and select the length of the seal of coverage hole before assembling, in this design, and only coverage hole rather than whole filter length.This equipment is arranged so that it arrives the block piece of expression filter passage when cigarette is placed in the machine, makes that it covers all holes when the plug for seal part is installed.This block piece is variable and can be according to the brand setting of the cigarette of using.
The blocking device that Fig. 4 shows according to the 4th embodiment is inserted into the signal shape of the mechanism on the cigarette by it.Each blocking device 80 side within it comprises the elastic sealing element 82 with lip, and this lip is clamped around the end parcel of blocking device and with it.This blocking device also comprises exhaust port 84, and it makes, and this device can be connected to vacuum when device is installed on the cigarette.
Blocking device 80 automatic or manuals are loaded in the mechanism to form the cylinder of the device of preparing installation.The device of installing forms the diameter bigger than release conditions by using vacuum expansion.Cigarette is loaded on the equipment and the vacuum that discharges allows seal to shrink and snugly center on filter in the passage zone cooperates.
The character of mechanism makes it possible to monitor vacuum to find passing the less of plug for seal part or than gross leak and provide the warning that should not use the sealing part and should replace.
Then cigarette is removed and is installed on the standard cigarette retainer that uses in the suction machine.
In case Fig. 5 shows cigarette when having inserted retainer cigarette retainer and blocking device.The parts of the retainer identical with previous embodiment give same numeral and are not described further.
In case suction end of run then abandon these seals.
Fig. 6 illustrates in greater detail some parts of seal installing mechanism.Referring to Fig. 6, setting can change the motor 90 of the position of variable block piece 92 under the control of control module 94.Control module 94 has the memory of the passage position of storage different brands cigarette.Before cigarette was placed in the machine, the operator entered the brand of cigarette by keypad 96.If perhaps cigarette is not the brand of control module identification, the operator can import the position of passage in the cigarette.Control module 94 makes seal cover some or all of passages when mounted by the position of motor 90 adjusting block pieces 92 then.
Form as an alternative is not the position of regulating block piece 92, but the position of adjustable sealing spare on being installed to cigarette the time.
Control module 94 is gone back the operation of control pump 98.98 pairs of seals of pump apply vacuum to make its expansion before inserting cigarette.In case cigarette is inserted, then discharges vacuum to allow the seal contraction and to cooperate around filter in the passage zone.
The detection of inefficacy seal
The detection of other flaw is very important to obtain consistent results in aspiration procedure on pin hole and the obstruction barrier film.More particularly, the position of passage is the part of so-called " strong suction " operating mode, and any paths that is drawn into smoking product at ventilation point air all can reduce measurement result and underestimate amount of substance in the master stream flue dust that is referred to as " tar ".This can cause result's highly variable in a word, can the result's of such acquisition validity be thrown doubt upon.
Fig. 7 shows the setting that can provide the simple inspection of pin hole and other flaw to guarantee making consistent seal around passage.This setting can be used for above-mentioned any embodiment, or in fact is designed for other purpose such as the seal of measuring pressure drop.
Referring to Fig. 7, plug for seal part S1 is placed on by pipeline and is connected in its formation part or keeper of valve V1, pump P1 and vacuum scale VG.In order to make cigarette can insert seal, pump P1 starts and valve V1 opens.This is to the regional exhaust that centers on of connecting pipe and obstruction barrier film.Barrier film S1 is pulled outwardly the hole that increases around forming the formation of part or keeper.Bigger hole makes the cigarette seal of can packing into.
Pressure between vacuum scale VG indication pump P1 and the flexible seals S1.Can indicate this pressure and it to compare by the analog or digital reading with the expection vacuum of pump and intact seal.If desired, can carry out this comparison by the operator.But, in shown in Figure 7 the setting, inefficacy seal probe unit D being set, it is compared actual pressure and the indication of inefficacy is provided when pressure is too high with predetermined critical.For example, can provide video or audio frequency to lose efficacy indicates alarm operation person's seal to lose efficacy.
This has guaranteed to survey " great " inefficacy before cigarette installs to seal.If the pressure of surveying is acceptable, then cigarette insertion seal and valve V1 are closed.
In the cigarette aspiration procedure, continue or the pressure among measurement line S1, VG, the V1 continually.Because do not have potted line and seal to be sealed by the perfect vacuum, all have the slow increase (loss of vacuum) of pressure.But the rate of change of calculating pressure and with the expection slip of intact seal relatively.In Fig. 7, carry out this calculating by probe unit D, and the indication of losing efficacy is provided when slip is too high.In addition, can provide video or audio frequency to indicate alarm operation person's seal to lose efficacy maybe will lose efficacy.Like this, can investigate the integrality of obstruction barrier film to guarantee the aspirating cigarette of blocking ventilation more in good condition.
Although below described preferred embodiment, can change within the scope of the present invention.For example in above all embodiment, be better than with vacuum and expand seal so that cigarette can be inserted, the sealing part can have the relaxation state that is slightly larger than cigarette, and can apply the pressure of increase so that its expansion and obstruction filtering holes to seal.In this case, vavuum pump will be substituted by the pump of supply increase pressure.
For example, seal can be made up of the pipe of pipe in the similar tire with the valve that is connected to pump.Because cigarette is inserted retainer, air is fed to pipe by valve.This tube expansion is aspirated cigarette simultaneously to block filtering holes then.In a single day test is finished and is just discharged this valve so that air can be overflowed, make pipe be retracted to its relaxation state that cigarette can be removed thus.
The present invention can be used for testing the smoking product except cigarette, such as cigar and cigarlet.
