Problems solved by technology

During use, some harmful substances (such as tar, etc.) in the mainstream smoke are intercepted by the filter fiber, but due to the limited length of the filter, the flow path of the smoke is short, and the flow direction is not conducive to being intercepted, etc., so the filtering effect is not good.

Embodiment 1

[0013] Embodiment 1: structure such as figure 1 As shown, it is composed of nozzle rod forming paper 4 and filter fiber tow 1, wherein, between the nozzle rod forming paper 4 and filter fiber tow 1, a layer of highly air-permeable filter paper with special grooves is sandwiched, so that The outer surface of the columnar body formed by wrapping the tow with filter paper is distributed with two sets of planar shapes 3 and grooved shapes 2 that are staggered up and down, left and right, and the groove-shaped arc surface is opposite to the planar arc surface. The molding paper 4 is wrapped and fixed to form a novel filter tip.

Embodiment 2

[0014] Embodiment 2: structure such as figure 2 As shown, on the outer surface of the columnar body formed by wrapping the tow 1 with filter paper, there are three sets of planar shapes 3 and grooved shapes 2 that are interlaced up, down, left, and right, and the others are the same as in Embodiment 1.

Abstract

The present invention discloses one new kind of filter tip for cigarette, and belongs to the field of cigarette producing technology. Before the filter tip forming paper and the filtering fiber tow, one layer of high permeability filter paper with special channels is set. When the cigarette is smoked, negative pressure is formed in the channel area to filter partial smoke and form S-shaped smoke flow path in longer distance. The present invention has increased collision possibility between the harmful smoke components and the filtering fiber and effective interception of harmful matter. Compared with traditional filter tip, the present invention has raised tar-reducing and harm-decreasing effect.

Description

technical field [0001] The invention relates to a novel filter tip for cigarettes, belonging to the technical field of cigarette manufacturing. Background technique [0002] In the traditional cigarette filter structure, there is a section of fiber filter rod with the same outer diameter as the cigarette wrapped in tipping paper, which is connected and fixed to the cigarette through the tipping paper on the outermost layer of the cigarette. During use, some harmful substances (such as tar, etc.) in the mainstream smoke are intercepted by the filter fiber, but due to the limited length of the filter tip, the flow path of the smoke is short, and the flow direction is not conducive to being intercepted, etc., so the filtering effect is not good. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a novel cigarette filter tip with reasonable design, simple structure, which can effectively increase the flow path of smok...
