Abstract

The present invention relates to filter tip for cigarette, and the filter tip of the present invention has filter element with at least one spiral passage. The spiral passage of filter element has no increase in air resistance, but increased smoke filtering length, greatly increased harmful matter adsorbing area and improved filtering effect of the filter tip.

Description

A kind of filter tip
Affiliated technical field
The present invention relates to a kind of cigarette filter.
Background technology
Existing filter tip is an end that is engaged on cigarette, it is the suction side, the filter core made from wadding fibrous material is enclosed in to be wrapped up in the paper, when smog is inhaled in the human body by filter core, part harmful substance is attracted in the filter core, has reduced the smoker to a certain extent to the soakage such as harmful substances such as tar.
Existing filter-tip structure mainly is divided into two kinds, and a kind of is that columniform filter core is enclosed in and wraps up in the paper, a filter-tip end have one with the bonding interface of cigarette.The shortcoming of this filter structure is the qualification that the filter tip axial length is subjected to the interfibrous void size of filter core, length increase along with filter core, the resistance corresponding increasing of smog when the filter core, as surpass certain-length then the smoker have sense of discomfort, influence the quality of cigarette; Another kind is the axially extending bore that has different cross section shape on the filter core, run through filter core as star, triangle etc., the suction side of directly leading to cigarette, the filter tip general axis of this structure is to longer dimension, its objective is not increasing vapour lock and must rise and put, increase the adsorption area of filter core with the structure that strengthens filter-tip axial dimension, thereby realize filter effect smog, its shortcoming is that the filter tip axial dimension is longer, obviously can weaken filtering function and shorten filter-tip length.Therefore, existing cigarette filter exists between filter tip axial length and the flue gas resistance, and the dual contradiction between filter tip axial length and the filter effect.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can improve filter effect, and the little cigarette filter of flue gas resistance.
For achieving the above object, a kind of filter tip of the present invention adopts and have the technical scheme of at least one helical duct in filter core.This helical duct has increased the length of smog by the path of filter core, has strengthened the adsorption area of filter core to a smog, and under action of centrifugal force, the harmful substance in the smog can be attracted on the conduit wall more.
First embodiment of the present invention is, described filter-tip filter core has and has the spiral fluted hole at least one hole wall, and described helicla flute can be a single head, also can be bull.
Second embodiment of the present invention is to have at least one on the described filter-tip filter core along the axially extended threaded hole of filter core.
The helical duct of a kind of filter-tip filter core of the present invention can be to connect this filter tip.
The helical duct of a kind of filter-tip filter core of the present invention also can be not connect this filter tip.
A kind of filter-tip filter core of the present invention can have a plurality of helical ducts.
After adopting said structure, the helical duct of a kind of filter-tip filter core of the present invention is under the prerequisite that vapour lock does not increase, increased the length of smog by the path of filter core, and increased the adsorption area of filter core, thereby reached the purpose of the filter effect that improves cigarette filter to harmful substance in the smog.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the cutaway view of a kind of filter-tip first specific embodiment of the present invention.
Fig. 2 is the cutaway view of a kind of filter-tip second specific embodiment of the present invention.
Fig. 3 is the cutaway view of a kind of filter-tip the 3rd specific embodiment of the present invention.
Fig. 4 is the cutaway view of a kind of filter-tip the 4th specific embodiment of the present invention.
The specific embodiment
At first referring to a kind of filter-tip first embodiment of the present invention shown in Figure 1.This filter tip comprises filter core 1, wraps up in skin 2 and interface 3, Fig. 1 illustrates described filter-tip filter core 1 and has the hole 4 that has helicla flute 5 on the hole wall, after smog enters filter core 1 through interface 3,4 is mobile to the direction away from interface 3 along the hole, a part of harmful substance in the smog is attracted to the surface of hole 4 walls and helicla flute 5, because the length of run of helicla flute 5 is greater than this filter-tip axial dimension, so its filter effect is better than the filter tip of prior art.
Referring again to Fig. 2 a kind of filter-tip second specific embodiment of the present invention is shown.As can be seen from Figure 2, has one on the filter core 1 along filter core 1 axially extended threaded hole 7, after smog enters filter core 1 through interface 3, flow to direction along threaded hole 7 away from interface 3, a part of harmful substance in the smog is attracted on the hole wall of threaded hole 7, because the length of run of threaded hole 7 is greater than this filter-tip axial dimension, so its filter effect is better than the filter tip of prior art.
A kind of filter-tip the 3rd specific embodiment of the present invention shown in Fig. 3.The hole 4 with band helicla flute 5 on this filter-tip filter core 1 is not connect filter core 1, one barrier layer 6 is arranged between hole 4 on this filter core 1 and the interface 3, the filter-tip filtration as prior art can be played in described barrier layer 6, and secondary filter has been carried out with smog in the hole 4 of coupled band helicla flute 5, causes filter effect better.
Fig. 4 illustrates a kind of filter-tip the 4th specific embodiment of the present invention.As can be seen from Figure 4, the structure of this helical duct is to have 4 threaded hole 7 on the filter core 1, this threaded hole 7 extends axially along filter core 1, after smog enters filter core 1 through interface 3, flow to direction by threaded hole 7 away from interface 3, a part of harmful substance in the smog is attracted on the hole wall of threaded hole 7, because the length of run of threaded hole 7 is greater than this filter-tip axial dimension, so its filter effect is better than the filter tip of prior art.
