Abstract

The utility model relates to a cigarette filter tip and a cigarette, which is characterized in that a group of smoke closure rods (5) embedded into the tow core rod axially along the tow core rod on the circle between the tow core rod (2) and the wrap paper (1); after the filter tip is connected to the cigarette (14), the filter tip and the cigarette are glued to be an integral cigarette by the tipping paper (15). The utility model has the advantages of largely improved efficiency of prevention of harmful smoke, simple structure, easiness for manufacturing and largely lower cost for the filter tip. Besides, absorption resistance of the filter tip can be adjusted with the diameter of the embedded material, and a traverse smoke closure performance is added to the filter tip. The utility model has little effect on fragrance of a cigarette.

Description

A kind of efficiently the dam Mouthpiece for cigarette and the cigarette of efficiently 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 to alleviate the harm of smoking to human body, but common filter rod just is made up of the forming paper of tow filter core rod and parcel, it is comparatively unobstructed that flue gas passes through the process of filter tip, and the harmful substance filter effect is relatively poor.For the filtration that improves flue gas or hold back efficient, occurred adding active carbon in a kind of mouth rod or other has the novel filter stick of high interception capacity, high adsorption material, though it makes the filtration of mouth rod or holds back efficient and significantly improve, but its manufacturing process is very complicated, used equipment complex is also very expensive, finally makes the cost of mouth rod rise bigger.Extensively retrieve at the problems referred to above, do not find the technical scheme relevant as yet with the utility model.

Summary of the invention

The purpose of this utility model is exactly the efficient filter rod of a kind of brand new that proposes in order to overcome the shortcoming that prior art exists.

To achieve these goals, the utility model has adopted following technical proposals: based on common filter rod, it is made up of the forming paper (individual layer or bilayer) of stranded core rod and outer parcel, it is characterized in that on the circumference between stranded core rod and the forming paper, one group of flue gas that embeds stranded core rod rod that dams axially is set along stranded core rod; Or along one group of flue gas that embeds stranded core rod ring that dams circumferentially is set.Described flue gas dam rod or flue gas dam ring also can be along the oblique setting of stranded core rod.The flue gas cut-off material can adopt nano material, absorbent charcoal material, carbon fibre material, mineral material, fabric or bioactive materials etc. to have highly-breathable, high adsorption, high selectivity or have the material of flexibility concurrently, quantity can be from 1-20, and concrete quantity and diameter can be determined according to the specification requirement of different cigarettes.In addition, stranded core rod also can wrap up two-layer forming paper, and wherein the internal layer forming paper is provided with the pit of rule or irregular alignment, and pocket wall is provided with very little passage.Can make the cigarette of efficiently damming with mouth rod with above-mentioned feature.

Advantage of the present utility model is: owing to adopted above-mentioned material and structure with highly-breathable, high adsorption, high selectivity and flexibility, make the utility model significantly improve to the efficient of holding back of harmful smoke, and it is simple in structure, easy to manufacture, the globality of mouth rod improves, and the cost of mouth rod significantly reduces.The resistance to suction of mouth rod can be regulated by the diameter of inlaid material, and has increased the mouth rod characteristic of laterally damming.Because on the cross section of mouth rod, inlaid material is not whole the covering, so this mouth rod is less to the fragrance influence of cigarette, therefore, the integral body of the present utility model efficient height that comprehensively dams is little to quality influence.

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

The specific embodiment:

As shown in Figure 1, every section T is symmetrical arranged 8 flue gases rod 3 that dams vertically on stranded core rod 2 circumference, its cross section as shown in Figure 4, be wrapped to form whole filter rod 5 by forming paper 1 then, cut off from cutting off line 4 during use, form 6 sections altogether and have the dam Mouthpiece for cigarette that efficiently dams of rod 3 of flue gas.Certainly, forming paper also can adopt the Mouthpiece for cigarette that efficiently dams that as shown in Figure 6 double-deck obbbin 9a, 10a form.

Shown in Fig. 2 left part, every section T (the same) dams and encircles 6 along 3-4 flue gas circumferentially is set on stranded core rod 2 circumference, be wrapped to form whole filter rod 5 by forming paper 1 then, its cross section as shown in Figure 5, cut off from cutting off line during use, form 6 sections altogether and have flue gas ring 6 the Mouthpiece for cigarette that efficiently dams that dams, every section total 3-4 mouth ring that efficiently dams.Flue gas dams ring also can be along the oblique setting of stranded core rod cylinder, shown in the label 7 on 3 the right of broken wires among Fig. 2.

As shown in Figure 3, the mouth rod 5 that efficiently dams is enclosed with outer forming paper 10 and internal layer forming paper 9, and the internal layer forming paper is provided with (extruding during manufacturing) pit 8, the shape of pit 8 can be rectangle, also can be rhombus or leg-of-mutton, shown in 11 among the figure, 12.The fit structure of internal layer forming paper 9 and stranded core rod 2 as shown in Figure 7, the pocket wall that internal layer paper forming paper 9 forms is provided with very little passage 8A, make flue gas enter pit 8, and then enter stranded core rod 2, shown in arrow among the figure by passage from the right along this hole.Because flue gas enters pit through aperture, amplify in the space, produces the condensation of flue gas, and harmful substances such as the tar in the flue gas are trapped within the pit, makes it to the filtration of flue gas and hold back effect and significantly improve.

The mouth rod 5 that efficiently dams that shown in Figure 8 is adopts Fig. 1 to provide props up 14 with cigarette and docks, and is bonded to the cigarette of efficiently damming of integral body then by yew paper 15.

The mouth rod 5 that efficiently dams that shown in Figure 9 is adopts Fig. 2 to provide props up 14 with cigarette and docks, and is bonded to the cigarette of efficiently damming of integral body then by yew paper 15.
