Abstract

The utility model relates to an irregular filter stick with a filter cartridge, relating to a filter stick for producing cigarette filter tips. The irregular filter stick comprises a cover layer (1) and a filter cartridge, and is characterized in that the filter cartridge consists of an outer filter cartridge (2) and an inner filter cartridge (3) which is embedded inside the outer filter cartridge (2) along the axial direction. The produced filter tip has a good effect of filtering harmful gas compositions and high anti-falsification. When mainstream smoke flows through the filter tip, the harmful substances such as tar and CO can be retained since the pressure drop between the inner filter cartridge and the outer filter cartridge can change the traveling path of the smoke gas in the filter tip.

Description

Abnormity filter core filter stick

Technical field

The utility model relates to the filter stick that is used to make cigarette filter.

Background technology

The existing fine filter stick of vinegar that is used to make cigarette filter, its made cigarette filter are good inadequately and antifalsification is strong inadequately to harmful smoke composition filter effect.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of good filtration effect and antifalsification strong special-shaped filter core filter stick.

Technical solution of the present utility model is: it comprises integument and filter core, and described filter core is made of outer filter core and inner filter core, and inner filter core connects embedding vertically and is rolled in the outer filter core.

Technique effect of the present utility model is: its made cigarette filter is strong to harmful smoke composition good filtration effect and antifalsification.When main flume is flowed through filter tip,, thereby hold back harmful substances such as more tar and CO because the pressure drop difference that inner filter core and outer filter core exist can change the travel path of flue gas in filter tip.

The specific embodiment

Embodiment one:

As shown in Figure 1, present embodiment comprises integument 1 and filter core, described filter core is made of outer filter core 2 and two inner filter cores 3 at least, outer filter core 2 is to be made by Celluloseacetate cigarette filter tow, inner filter core 3 is made by Celluloseacetate cigarette filter tow or other materials, and inner filter core 3 connects embedding vertically and is rolled in the outer filter core 2.Inner filter core 3 is a white or colored.

As shown in Figure 2, described inner filter core 3 is wrapped with shaping paper 4.Described outer filter core 2 outer integuments 1 are shaping paper 4.Shaping paper 4 can be white or colored.

Described inner filter core 3 its cross sections are circular.

Embodiment two:

As shown in Figure 3, different with embodiment one is that described inner filter core 3 its cross sections are triangle.Its outer no shaping paper bag is wrapped up in.

Embodiment three:

As shown in Figure 4, different with embodiment one is that described inner filter core 3 its cross sections are rectangle.Its outer no shaping paper bag is wrapped up in.

Embodiment four:

As shown in Figure 5, different with embodiment one is that described inner filter core 3 its cross sections are four jiaos of stars.Its outer no shaping paper bag is wrapped up in.

Embodiment five:

As shown in Figure 6, different with embodiment one is that described inner filter core 3 its cross sections are pentalpha.Its outer no shaping paper bag is wrapped up in.

Embodiment six:

As shown in Figure 7, different with embodiment one is that described inner filter core 3 its cross sections are heart-shaped.Its outer no shaping paper bag is wrapped up in.

The utility model is reasonable in design, adopts two kinds of bigger filter cores of pressure drop difference to form, and flue gas flow direction is changed, and air-flow is advanced along the passage of different resistances, reduces harmful substances such as tar, CO in the flue gas thereby reach.When using this mouth excellent, can choose various combination of materials, length and circumference.The designer just can control the flue gas path like this, the rejection of T/N, the minimizing degree and the resistance to suction of carbon monoxide.The good flexibility of this filter stick has guaranteed that each specification all is to have passed through accurate design, and the client suits one's taste and the requirement of strainability thereby can satisfy best, and then strengthens brand image.

This filter stick can independently use, and also can make binary, ternary, quaternary composite filter with the filter stick that adds different materials.
