Abstract

The utility model relates to a nozzle stick and cigarette. The nozzle stick and cigarette is characterized in that inner layer paper 3 is wrapped up a core rod 1, and the outer layer of the core rod 1 is wrapped up forming paper 2 again; a groove 4 is arranged on the inner layer paper, and small holes are arranged on both walls of the groove. Thus, the core rod forms at least one annular groove along the circumferential direction. The nozzle stick and cigarette has the advantages that the groove 4 is used for extruding tows to a shaft core to increase density, and the longitudinal cut-off efficiency is raised. In addition, a part of flue gas S enters the groove from the small holes, so the flue gas is transversely cut off twice at a groove area and is condensed. Thus, the flue gas is further cut off, that is, longitudinal and transverse cut-off, and the whole general cut-off of the condensation cut-off of a cavity of the groove are formed. Thus, the cut-off efficiency of the nozzle stick is raised.

Description

A kind of integral body mouth rod and integral body cigarette of damming of damming

Technical field

The utility model relates to tobacco product, particularly relates to a kind of cigarette of filter rod and band filter rod thereof of cigarette.

Background technology

At present generally adopt cigarette to prop up to install filter rod additional and alleviate the harm of smoking human body, but common filter rod just is made up of the forming paper of tow filter core rod and parcel, flue gas is comparatively unobstructed by the process of filter tip, owing to just vertically dam, limited to harmful components filter effects such as tars.For the efficient of damming that improves the mouth rod to satisfy the requirement of people to health, satisfy people again to the smoking demand simultaneously, must change original filter rod structure, reduce harmful ingredients in flue gas better and reduce tar content to reach.

Summary of the invention

The purpose of this utility model is exactly to increase laterally damming of mouth rod on original basis of vertically damming, so that the maximum efficient of damming of the whole performance of mouth rod.

To achieve these goals, the utility model has adopted following technical proposals: based on common filter rod, it comprises the forming paper of stranded core rod and parcel thereof, it is characterized in that stranded core rod parcel one deck internal layer paper earlier, its skin wraps up forming paper again, be shaped on the groove embossing on the described internal layer paper, groove two walls are provided with aperture, make the stranded core rod upper edge circumferentially form at least one annular groove.Internal layer paper is tobacco business fiber filter paper commonly used, also can be the cigarette paper of other type, and embossing can carry out equidistantly or not equidistant arrangement.Internal layer paper enters opium pipe synchronously with outer paper after being pressed into required groove by emboss, stranded core rod is rolled into filter rod, because the effect of plasticizer (triacetyl glycerine) is arranged in the stranded core rod, make tow by the moulding of internal layer paper shape, form concaveconvex structure between stranded core rod and internal layer paper and the outer paper simultaneously.Excellent the propping up with cigarette of above-mentioned mouth sticked to one cigarette with yew paper thereby the formation unitary whole is dammed.

Advantage of the present utility model is: because annular groove inwardly pushes stranded core rod, its density is increased, at first increased the efficient of vertically damming; Other has partial fume to enter groove by aperture, and then returns stranded core rod by aperture, and this has just increased by twice and has laterally dammed, also because the aperture amplification principle has the partial fume condensation, therefore when flue gas enters groove, the utility model has been realized wholely comprehensively damming, and its efficient significantly improves.

For the utility model is described in further detail, following accompanying drawing provides a most preferred embodiment.

Description of drawings:

Fig. 1 is the front view of mouth rod described in the utility model, makes continuous mouth rod during manufacturing, therefrom cuts off during use;

Fig. 2 is the A place partial enlarged drawing among Fig. 1;

The cutaway view that the integral body that Fig. 3 is to use mouth rod shown in Figure 1 to make is dammed cigarette.

The specific embodiment:

As shown in Figure 1, stranded core rod 1 first wrapping inner layer paper 3, then in parcel forming paper 2, (quantity of groove can be from 1-10 along the circumferential grooves distributed 4 of plug to be provided with 3 roads among every section T on the internal layer paper 3, meaningless too much, be good with 2-5), two walls of each groove 4 are provided with aperture 4a, 4b, aperture circumferentially distributes along plug, and 1-10 row (as shown in Figure 2) can be set.Cut off 3 mouth rods of formation from label 5 during use.Each mouth rod 8 usefulness yew paper 6 props up the 7 bonding cigarettes that become to have the mouth rod with cigarette, as shown in Figure 3.The integral body of mouth rod is dammed situation as shown in Figure 2, because groove 4 to axis direction P extruding stranded core rod, makes this section tow density increase, this place (vertically) efficient of damming increases; Because this place's resistance is big, partial fume S flows (laterally) to little groove 4 directions of pressure in addition, and 4a enters groove from aperture, enter aperture 4b from groove, returns stranded core rod then, thereby flue gas is laterally dammed through twice at groove area.In addition, because flue gas is from aperture person who lives in exile groove, used the aperture amplification principle, flue gas obtains condensation at groove, flue gas is further dammed in groove, thereby the flue gas that enters opposite side is reduced, so just brought into play the mouth rod vertically, laterally dam, the integral body that aperture amplifies, the groove cavities condensation is dammed is dammed comprehensively, thereby the mouth rod efficient of damming is significantly improved.Size, the quantity of described internal layer paper depth of groove and both sides hole diameter can be carried out co-design according to nozzle rod sucting resistance specification requirement and interception capacity.

Claims (2)

1, a kind of integral body mouth rod that dams, it is made up of the forming paper of stranded core rod and outer parcel, it is characterized in that stranded core rod parcel one deck internal layer paper earlier, its skin wraps up forming paper again, be shaped on the groove embossing on the described internal layer paper, groove two walls are provided with aperture, make the stranded core rod upper edge circumferentially form at least one annular groove.

2, a kind of integral body cigarette of damming, it is by mouth rod and cigarette Zhi Zucheng, it is characterized in that described mouth rod adopts the described integral body of the claim 1 mouth rod that dams.
