Abstract

The utility model relates to a composite filter tip rod which comprises a filter core rod, forming paper and tipping paper; the forming paper is wrapped outside the filter core rod; the tipping paper is wrapped outside the forming paper; the filter core rod comprises two sections of filter core which are butted; the filter core on a suction end comprises a tubular outer core wrapped outside a cylindrical inner core, and the forming paper wrapped outside the outer core; and the filter core on the end butted with a cigarette comprises the forming paper wrapped outside the cylindrical core rod. The composite filter tip rod has reasonable structure and good filtration effect, and is an ideal filter tip rod for low-tar and ultra low-tar cigarette products.

Description

A kind of composite filter tip

Technical field

The utility model relates to the cigarette industry technology, specifically a kind of composite filter tip of cigarette.

Background technology

Along with people to the increasing of the composition understanding of being harmful to health in the tobacco, the influence that the compound in the cigarette smoke may cause the smoker is by growing interest, the cigarette lowering harm and decreasing coking has become the research tendency and the emphasis of tobacco business.At present, generally the filter rod of Shi Yonging is to be rolled into type paper and yew paper constitutes by acetate silk plug outside, flue gas is very fast by the process of this filter rod, it only plays general filtration, filter effect is not ideal enough, this present situation has seriously restricted cigarette product, and especially low tar, ultra-low tar cigarette Products Development are produced.

The utility model content

The purpose of this utility model is to provide a kind of composite filter tip, and it is to the filter efficiency height of cigarette, and harmful components effective in the absorption flue gas.

For achieving the above object, the utility model adopts following scheme: a kind of composite filter tip, include filter core rod, forming paper and yew paper, it is outside that forming paper is wrapped in the filter core rod, the yew paper bag is rolled in the outside of forming paper, the filter core rod is made of the butt joint of two sections filter cores, and inner core outside, forming paper that the filter core that is positioned at aspiration end is wrapped in column by the outer core of tubulose are wrapped in outer core outside and constitute, and is positioned at the filter core that props up the butt end with cigarette and is wrapped in columned plug outside by forming paper and constitutes.

By such scheme as seen, because being positioned at one section filter core of aspiration end, the composite filter tip that the utility model provides has inner core and outer core, the two-part resistance to suction difference of this section filter core, when flue gas passes through, flue gas can along inner core with outside the channel flow of the formed different resistances of core, thereby this section filter core can improve the filter efficiency to flue gas, realizes adsorbing effectively the harmful components in the flue gas; In addition, add adsorbent targetedly propping up on the filter core of butt end, can reach the effect of the harmful components in the selectable absorption flue gas with cigarette.

The utility model is rational in infrastructure, good filtration effect, and it is low tar, the comparatively ideal filter rod of ultra-low tar cigarette product.

Description of drawings

The structure chart of Fig. 1 the utility model one embodiment;

The A-A cutaway view of Fig. 2 Fig. 1.

The specific embodiment

Further specify the utility model below in conjunction with embodiment and accompanying drawing.

Referring to Fig. 1, the composite filter tip that the utility model provides, include filter core rod, forming paper 2 and yew paper 1, the filter core rod is made of filter core 4, filter core 3 butt joints, inner core 3c outside, forming paper 3b that the filter core 3 that is positioned at aspiration end is wrapped in column by the outer core 3a of tubulose are wrapped in outer core 3a outside and constitute, be positioned at the filter core 4 that props up the butt end with cigarette and be wrapped in columned plug 4a outside by forming paper 4b and constitute, it is outside that forming paper 2 is wrapped in the filter core rod, and yew paper 1 is wrapped in the outside of forming paper 2.In addition, have somely along its circumferential uniform through hole 1a on yew paper 1, the employing high-air-permeability forming paper of forming paper 2, forming paper 3b, forming paper 4b correspondence can make this cigarette filter rod form the ventilation filter stick.The material of outer core 3a, inner core 3c, plug 4a is existing acetate silk, and used forming paper, the yew paper of forming paper 3b, forming paper 4b, forming paper 2 and yew paper 1 and existing filter rod is identical.For improving adsorption effect, can in the tow of plug 4a, add sorbent materials such as active carbon, tea Dove, chitin, hemoglobin, nano material targetedly.

Referring to Fig. 2, inner core 3c is cylindrical, and outer core 3a is wrapped in the inner core 3c outside of column and both are coaxial.Forming paper 2 is wrapped in forming paper 3b outside, and yew paper 1 is wrapped in the outside of forming paper 2.In addition, can make inner core 3c is different colors with outer core 3a, like this, can make this filter rod have the sensation of novelty, uniqueness in appearance, and have certain antifalse effect.

Claims

1, a kind of composite filter tip, include filter core rod, forming paper and yew paper, it is outside that forming paper is wrapped in the filter core rod, the yew paper bag is rolled in the outside of forming paper, it is characterized in that: the filter core rod is made of two sections filter core butt joints, inner core outside, forming paper that the filter core that is positioned at aspiration end is wrapped in column by the outer core of tubulose are wrapped in outer core outside and constitute, and are positioned at the filter core that props up the butt end with cigarette and are wrapped in columned plug outside by forming paper and constitute.

2, composite filter tip according to claim 1 is characterized in that: have some along its circumferential uniform through hole on yew paper.
