Embodiment 1

[0031] like figure 1 As shown, the cigarette of this embodiment includes a filter tip 1 and a cut tobacco rod 3, and a hollow tube 6 (made of cigarette paper) is arranged along the axial direction of the cut tobacco rod. A porous material 7 is arranged at the joint between the tube and the filter, and the shape is a circular piece with an area equal to the cross-sectional area of ​​the cut tobacco rod. The control sample of the present invention is a conventional cigarette, the air permeability of the cigarette paper is 70 CU, and the number of cigarettes tested by the smoking machine is 20. In order to describe its effect more accurately, the CO emission in the smoke is calculated by grams of shredded tobacco, and the test results are shown in Table 1 ( Example 1).

Embodiment 2

[0033] like Figure 5 As shown, the cigarette of this embodiment includes a filter tip 1 and a cut tobacco rod 3, and a hollow tube 6 (material is cigarette paper) is provided along the axial direction of the cut tobacco rod. The cross section of the hollow tube is circular and the diameter is 2 mm. . A porous material 7 is arranged at the junction of the hollow tube and the filter tip, the shape is a circular piece, the center is on the central axis of the cigarette, and the diameter of the circular piece is 3 mm. The control sample of the present invention is a conventional cigarette, the air permeability of the cigarette paper is 70 CU, and the number of cigarettes tested by the smoking machine is 20. In order to describe its effect more accurately, the CO emission in the smoke is calculated by gram weight of shredded tobacco, and the test results are shown in Table 1. (Example 2).

Embodiment 3

[0035] like Image 6 As shown, the cigarette of this embodiment includes a filter tip 1 and a cut tobacco rod 3, and a hollow tube 6 (material is cigarette paper) is arranged along the axial direction of the cut tobacco rod. The cross section of the hollow tube is circular and the diameter is 2.5 mm. . A cylindrical cellulose porous material with a length of 2 mm is embedded at the junction of the hollow tube and the filter. The control sample of the present invention is a conventional cigarette, the air permeability of the cigarette paper is 70 CU, and the number of cigarettes tested by the smoking machine is 20. In order to describe its effect more accurately, the CO emission in the smoke is calculated by gram weight of shredded tobacco, and the test results are shown in Table 1. (Example 3).

Abstract

A cigarette with a porous material comprises a filter tip and a tobacco shred stick, and is characterized in that a hollow tube is axially arranged in the tobacco shred stick, and the porous material is arranged at a position where the hollow tube is connected with the filter tip. The structure of the cigarette is improved, and enough air is provided for combustion of tobacco shreds in a burning and smoking process of the cigarette to reduce CO gas generated by incomplete combustion of the tobacco shreds at high temperature. The original overall size of the cigarette is not changed, the CO release amount of the cigarette and smoking temperature of mainstream smoke can be reduced obviously on the premise of not changing the original smoking taste, and therefore, consumers can receive the cigarette.

Description

technical field [0001] The invention relates to a cigarette structure, in particular to a cigarette provided with porous materials. Background technique [0002] In the smoking state of cigarettes, conventional cigarette tip sticks (formed paper wrapped acetate tow) can significantly reduce the tar particles in the smoke, but it is harmful to the volatile components in the gas phase components of cigarette smoke (main and side flow smoke). Substance filtering effect is poor. [0003] Carbon monoxide (CO) is a kind of harmful gas with relatively high content in the gas phase of cigarette smoke. The CO release amount of each cigarette is between 1-20 mg. Carbonyl compounds, etc.) thermal cracking at high temperature, incomplete combustion of tobacco and CO at high temperature 2 The reduction of three pathways produced. In terms of the reduction of CO in cigarette smoke, domestic and foreign researchers have carried out a lot of research in all aspects of the tobacco leaf an...
