Description of drawings
Fig. 1, Fig. 2 and Fig. 3 show is the structural profile schematic diagram that the utility model is sucked the filter stick that tobacco uses.
Element numbers explanation in the accompanying drawing:
2 filter cores; 4 corrugation forming paper; 6 forming paper.
The specific embodiment
The utility model is sucked the used filter stick of tobacco, comprises a ductile filter core of breathable, and the outer surface of filter core is wrapped in the corrugation forming paper that ground floor adopts gas permeable material to make, and this layer corrugation forming paper outside also is wrapped in second layer forming paper.The corrugation forming paper of ground floor is the forming paper of corrugated, forms at least one elongate groove longitudinally with second layer forming paper.Every groove has end sealing or driving fit at least.(for example :), the preferably degree of depth of every groove and longitudinal length basically identical though may change in the position of groove near blind end.Usually, the filter core of whole length can be breathed freely.
Characteristics of the present utility model are, filter core uses the fibrous material that has bonding composition (as ultimate fibre, preferably the ultimate fibre of the cellulose acetate through curling).The ground floor forming paper is an independent corrugation forming paper (corrugated forming paper) preferably.
Actual effect proves that filter stick of the present utility model is compared with the traditional filter tip that does not install ground floor corrugated forming paper additional, can more effectively filter special compound (as tar).When using the smoking of the utility model filter stick, because filter cartridge construction adopts the corrugated forming paper design of flue gas, so all cigarettes from passing through between second layer forming paper and the corrugated paper.In addition, second layer forming paper is ventilative, and when making this filter tip smoking, extraneous air can enter groove between ground floor and the second layer forming paper by second layer forming paper.Experiment showed, filter stick of the present utility model carbon monoxide in the filtering flue gas effectively, outstanding than the strainability of traditional cigarette filter tip.
When making the utility model filter stick, carefully control the corrugation of ground floor forming paper, it may influence the increase rate (comparing with traditional filter tip) of strainability.In addition, can also can see these grooves at the end of finished product filter tipped cigarette by changing the outward appearance that gash depth, groove number and groove pitch change filter tip.Obviously, for the filter tip of set circumference, widen groove and will reduce groove number.For example, be about 8 millimeters filter stick for diameter, the longitudinal groove quantity between ground floor and the second layer forming paper is usually between 14 to 22.Total cross-sectional area of these grooves reaches 3%～10% of the total cross-sectional area of filter tip usually.Obviously, if the diameter of filter stick becomes big or diminishes, these numerals also can change.
According to utility model, in the cigarette of band filter stick, longitudinal groove may opened at the mouth end, or opens to pipe tobacco.Some grooves may reach an end of filter stick, and other groove then may reach the other end of filter stick, but every groove at least all can stop at filter stick one end.Therefore, can design a filter stick end outward appearance (the mouth end at filter stick can be seen groove) or a traditional filtering mouth rod end outward appearance (groove is in abutting connection with the pipe tobacco end of filter stick) to cigaratte filter.Unique filter stick end outward appearance helps false proof.
Table 1 compares the pressure drop of traditional plain weave acetate fibre filter tip (contrast 1 and 2) and the pressure drop and the tar retention value of tar retention value and two filter sticks of the present utility model (sample 1 and sample 2).The pressure drop (representing with the millimeter of water) of contrast filter stick and sample filtering mouth rod is consistent, and it is high by 5% that the while can also see that the tar of the utility model filter stick is held back efficient comparison photograph filter stick.In addition, as shown in table 2, when the identical tar of acquisition was held back efficient, the resistance to suction of the utility model filter stick was also low than traditional acetate fibre filter tip.In this table, the contrast filter stick is consistent with the tar maintenance dose of sample filtering mouth rod, and that the pressure drop of the utility model filter stick (resistance to suction) is held back the identical traditional acetate fibre filter tip of efficient than tar is low, is the 28-36 millimeter of water.
What Fig. 1-3 showed is the generalized section of the utility model filter stick corrugation part.These schematic diagrames comprise a cellulose acetate tow filter core 2 that is bonded together (corrugation by breathable corrugated forming paper 4 partly wraps up), the 6th, outer forming paper.In each case, filter core 2 is substantially the same.Fig. 1 shows is that diameter is 8 millimeters and has the filter tip of 22 grooves, 0.20 millimeter of every ditch groove depth, and spacing is 1.20 millimeters, accounts for mouth and filters 3.5% of total cross-sectional area.Fig. 2 shows is that diameter is 8 millimeters and has the filter tip of 15 grooves, 0.45 millimeter of every ditch groove depth, and spacing is 1.50 millimeters, accounts for mouth and filters 10.2% of total cross-sectional area.Fig. 3 shows is that diameter is 8 millimeters and has the filter tip of 23 grooves, 0.32 millimeter of every ditch groove depth, and spacing is 1.05 millimeters, accounts for mouth and filters 6.4% of total cross-sectional area.These schematic view illustratings can how influence the outward appearance and the characteristics of filter tip by the corrugation of control corrugated forming paper.
Filter stick of the present utility model can install one deck breathable forming paper (can be natural poromeric material and/or punching forming paper) in corrugated forming paper outside additional.Outer forming paper can be airtight.Outer forming paper can be the tipping paper that connects filter tip and filter tipped cigarette, and this outer forming paper is only used in the cigarette production phase.So the filter rod of initial production can be seen ventilative corrugation forming paper, the finished product filter tip that the utility model comprises this filter rod and installed outer forming paper additional.
