Embodiment 1

[0023] This example is attached Figure 4 As shown, including the filter tip 1 and the shredded tobacco rod 5, in the present embodiment, two large semicircular shape baffles 3 are arranged in the cigarette filter tip, the area is 60% of the circular area of ​​the cross section of the filter tip, and the cellulose material is in the form of Cross distribution, the baffle spacing is 6 mm; the baffle is perpendicular to the axial direction; the diameter of the through holes 4 on the baffle is 10 μm, and the hole spacing is 1 mm. The structure of the control sample is similar to that of Example 1, except that the baffle is a solid structure, which is recorded as Control 1. The smoking resistance of cigarettes and the release levels of tar and CO during the smoking process are shown in Table 1.

Embodiment 2

[0025] This example is attached Figure 5 As shown, including the filter 1 and the shredded tobacco rod 5, in the present embodiment, 4 porous fan-shaped baffles 3 are arranged in the cigarette filter, and the α angle is 80° o , in a staggered distribution, the distance between the baffles is 4 mm; the diameter of the through holes 4 on the baffle is 30 μm, and the distance between the holes is 0.8 mm. The structure of the control sample is similar to that of Example 2, except that the fan-shaped baffle is a solid structure, which is recorded as Control 2. The smoking resistance of the cigarette and the tar and CO release levels during the smoking process are shown in Table 1.

Abstract

The invention relates to a cigarette with baffle plates in a filter tip. The cigarette comprises a filter tip and a cut tobacco rod, and is characterized in that at least two baffle plates are arranged in the filter tip in a direction being vertical to the axial direction, and are in a flaky shape; the shape is a big half circle shape or a fan shape; a plurality of through holes are formed in each baffle plate. By improving the structure of the cigarette filter tip, in the cigarette combustion and smoking process, the porous baffle plates are used for simultaneously achieving the two effects of prolonging the circulation path of partial smoke gas in the filter tip and enhancing the smoke gas returning and mixing effect, so that the absorption performance of acetic acid fiber can be sufficiently and effectively achieved; further, the tar and CO release quantity in the main stream smoke gas can be reduced. The cigarette has the advantages that the original integral dimension of the filter tip and the cigarette smoking resistance are not changed; the acceptance by customers is convenient.

Description

technical field [0001] The invention relates to a cigarette structure, in particular to a cigarette with a baffle in the filter tip. Background technique [0002] In order to reduce the particulate matter in cigarette smoke, filter cigarettes were produced on a large scale in the early 1950s. The removal of particulate matter in smoke by filters mainly depends on the mechanical filtration effect of fiber tow on aerosols. Conventional cigarette filters can reduce the particulate matter of tar in smoke to a certain extent, but limited by the length of the filter, the removal of tar cannot After all, the effect is limited. Although the tar amount of a single cigarette can be further reduced by lengthening the filter tip at present, an excessively long filter tip will affect the overall appearance of the cigarette. In addition, the filtering effect of the filter on the volatile harmful substances in the gas phase components of cigarette smoke is relatively poor. Carbon monoxide...
