Abstract

The utility model relates to a filter candle with a carbon absorbing core and a filter tip, comprising a carbon core (1) coiled by an activated carbon fiber layer and cellulose acetate (2) provided outside of the carbon core. The carbon core coiled by an activated carbon fiber layer which is coiled in the cellulose acetate is added into the filter candle and the filter tip of the utility model. Thereby, the carbon core is fixed without easy desquamation. Absorbing abstractions of the filter candle and the filter tip are same, which effectively reduces the volatile and the sub-volatile harmful substances in the main smoking such as nitrite, benzopyrene, cypress oil and the like. Further, the carbon core which is coiled by activated carbon fiber layer and which is added into the filter candle and the filter tip has the function of counterfeit deterrence.

Description

The filter stick and the filter tip that have the adsorbent charcoal core

Technical field

The utility model relates to filter stick and the filter tip that a kind of cigarette filter is used, and particularly has the filter stick and the filter tip of adsorbent charcoal core.

Background technology

At present, along with growing to even greater heights and the generally enhancing of consumer of the anti-cigarette motion in the world to smoking and health perception, the pressure that tobacco business faces is increasing, when tar and harmful components thereof were reduced, keeping cigarette odor-absorbing to make the consumer obtain that physiology satisfies again was the ultimate challenge that the cigarette design faces.Cigarette filter stick 90% is made up of single acetate fiber at present, though some patent disclosure form by the filter stick of a section or plurality of sections carbon rod and a section or plurality of sections cellulose acetate, but the carbon rod in this filter stick because and just mutually arrange between the acetate fiber rod and form, in transportation, carbon rod comes off easily; And one section is carbon rod in filter stick, and one section is cellulose acetate, and flue gas is different with the resistance to suction of passing through cellulose acetate by the resistance to suction of carbon rod, so the adsorption capacity of carbon rod reduces greatly.

Summary of the invention

The purpose of this utility model is to reduce tar and harmful components thereof in the cigarette smoke further, and a kind of filter stick and filter tip that has the adsorbent charcoal core is provided.

The utility model is achieved through the following technical solutions:

A kind of filter stick that has the adsorbent charcoal core of the present utility model, it comprises: the charcoal core that is rolled into by the NACF layer and at the cellulose acetate in its outside;

A kind of filter stick that has the adsorbent charcoal core of the present utility model, wherein: the diameter of described charcoal core is the 0.5-3 millimeter;

A kind of filter stick that has the adsorbent charcoal core of the present utility model, wherein: the diameter of described charcoal core is 2 millimeters;

A kind of filter stick that has the adsorbent charcoal core of the present utility model, wherein: the length of the NACF in the described charcoal core is the 1-5 millimeter;

A kind of filter stick that has the adsorbent charcoal core of the present utility model, wherein: the length of described NACF is 3 millimeters;

A kind of filter tip that has the adsorbent charcoal core of the present utility model, wherein: it comprises: forming paper, yew paper and filter stick, wherein: described filter stick comprises: the charcoal core that is rolled into by the NACF layer and at the cellulose acetate in its outside;

A kind of filter tip that has the adsorbent charcoal core of the present utility model, wherein: the diameter of described charcoal core is the 0.5-3 millimeter;

A kind of filter tip that has the adsorbent charcoal core of the present utility model, wherein: the diameter of described charcoal core is 2 millimeters;

A kind of filter tip that has the adsorbent charcoal core of the present utility model, wherein: the length of the NACF in the described charcoal core is the 1-5 millimeter;

A kind of filter tip that has the adsorbent charcoal core of the present utility model, wherein: the length of described NACF is 3 millimeters.

The utlity model has following remarkable advantage:

The utility model is added with the charcoal core that is rolled into by the NACF layer in filter stick and filter tip, the charcoal core is wrapped in the centre of cellulose acetate, therefore be not easy to come off, and filter stick is identical with filter tip resistance to suction everywhere, the harmful substance that can reduce volatility and half volatile in the main flume most effectively is as nitrite, BaP, tar etc., and is added with the charcoal core that the NACF layer is rolled into also has false proof function in filter stick and filter tip.
