AI Technical Summary
While the prior art reduces the tar content of cigarettes, the nicotine content has not been significantly reduced, and the uneven combustion of traditional cigarettes leads to unstable release of harmful substances.
The cigarette branch structure is adopted which is composed of carbonized tobacco wire or tobacco powder filling the central axis and uncharged tobacco wire. The carbonized tobacco wire is formed by heating low-quality tobacco wire in an oxygen-deficient environment, and the outer periphery is wrapped by high-quality uncharged tobacco wire to maintain the fragrance of tobacco and reduce the release of harmful substances.
Significantly reduces the release of tar and nicotine, improves combustion stability, reduces resource waste, and maintains tobacco flavor.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tobacco processing, in particular to a low-hazard cigarette. Background Art
[0002] During the combustion process, the temperature distribution of a traditional cigarette's combustion cone is uneven, with high temperatures concentrated in the center. The high temperatures in the tobacco shreds cause the pyrolysis of tobacco, producing a large amount of harmful substances. The lower temperatures at the periphery of the combustion cone produce less harmful substances, such as tar. However, regardless of the location of the combustion cone, nicotine is released into the smoke as it is released. While its content is not directly controlled by the temperature distribution, the combustion process affects its release rate and total amount. With increasing health awareness, traditional tobacco products have attracted widespread attention due to their high tar and harmful substance content. Existing technologies often aim to reduce tar and harm by increasing the ventilation rate of cigarette filters. However, while this approach effectively reduces the total amount of tar in smoke, it suffers from a significant drawback: nicotine content is not reduced accordingly. Nicotine is an alkaloid in tobacco. Its formation and release are related to the combustion process but not entirely dependent on the completeness of combustion. Nicotine content in tobacco is relatively stable, and the amount released into smoke is affected by various factors, such as tobacco type, processing method, and combustion conditions. However, increasing the filter's ventilation rate primarily affects combustion conditions and has limited impact on nicotine formation and release. Consequently, while tar content is reduced, nicotine levels are not reduced accordingly. Therefore, developing a less harmful cigarette is crucial. Utility Model Content
[0003] In view of the above problems, the purpose of the present invention is to provide a low-hazard cigarette, which reduces the release of tar and harmful substances in cigarettes by improving the structural combination of cigarettes while maintaining the original flavor of tobacco.
[0004] In order to achieve the above objectives, the present invention adopts the following technical solutions:
[0005] A low-hazard cigarette, comprising a tobacco segment wrapped in cigarette paper, wherein the tobacco segment is composed of two types of tobacco, the central axis portion of the tobacco segment is filled with carbonized tobacco (including leaf and stem cuts) or tobacco powder, and the portion outside the central axis is filled with traditional uncarbonized tobacco, wherein the cross-sectional diameter of the filled carbonized tobacco or tobacco powder is 1 / 5 to 1 / 2 of the diameter of the entire cigarette.
[0006] Furthermore, the carbonized shredded tobacco or tobacco powder is formed by carbonizing low-quality shredded tobacco; the uncarbonized traditional shredded tobacco is selected from high-quality shredded tobacco to maintain the natural taste and flavor of traditional cigarettes.
[0007] The carbonized cut tobacco, cut stems or tobacco powder is formed by heating low-quality cut tobacco to 220° C.-320° C. in an oxygen-deficient environment and maintaining the temperature for 1-2 hours.
[0008] The carbonized tobacco is subjected to moisture conditioning before rolling to improve its processing resistance.
[0009] Select an appropriate amount of tobacco as the outer material and place the carbonized tobacco rod in the center of the cigarette making machine or special equipment.
[0010] The carbonized tobacco rod is wrapped with outer tobacco shreds. This process may require the use of a glue sprayer or other bonding device to ensure that the outer tobacco shreds can adhere tightly to the carbonized tobacco rod. The wrapped tobacco rod is further processed into cigarettes that meet the requirements through the rolling device of the cigarette rolling machine or manual operation.
[0011] In addition, traditional shredded tobacco can be mixed with carbonized shredded tobacco or tobacco powder before being rolled into cigarettes, that is, the tobacco segments are composed of a mixture of carbonized shredded tobacco and traditional shredded tobacco, and the mixing ratio of carbonized shredded tobacco to traditional shredded tobacco is 1:3.
[0012] Compared with the prior art, the utility model has the following advantages:
[0013] (1) Significantly reduce the tar content, carbon monoxide and nicotine release in tobacco products.
[0014] (2) Through carbonization treatment, the combustibility of tobacco is improved, making the combustion more stable.
[0015] (3) The utilization rate of low-quality tobacco leaves was improved and resource waste was reduced.
[0016] (4) It retains the original aroma of tobacco and satisfies consumers’ demand for tobacco flavor. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below with reference to the accompanying drawings (embodiments).
[0021] Example 1:
[0022] like Figure 1As shown: A low-hazard cigarette, including a tobacco segment wrapped by cigarette paper 3, the tobacco segment is composed of two types of tobacco, the central axis portion of the tobacco segment is filled with carbonized tobacco 1, and the portion outside the central axis is filled with uncarbonized traditional tobacco 1, and the cross-sectional diameter of the filled carbonized tobacco 1 is 1 / 5 to 1 / 2 of the diameter of the entire cigarette.
[0023] Furthermore, the carbonized shredded tobacco 1 is formed by carbonizing low-quality shredded tobacco; the uncarbonized traditional shredded tobacco is selected from high-quality shredded tobacco to maintain the natural taste and flavor of traditional cigarettes.
[0024] The carbonized shredded tobacco 1 is formed by heating low-quality shredded tobacco to 220° C.-320° C. in an oxygen-deficient environment and maintaining the temperature for 1-2 hours.
[0025] The carbonized tobacco shreds 1 are subjected to moisture conditioning before rolling to improve their processing resistance.
[0026] The corresponding test data of this utility model are as follows:
[0027] Ratio of carbonized tobacco to cigarette diameter Tar content (mg) Nicotine content in smoke (mg) Flue gas carbon monoxide content (mg) 0 10 1 10 1 / 5 8.1 0.79 8.5 1 / 4 7.65 0.75 8.2 1 / 3 6.92 0.64 7.1 1 / 2 5.33 0.55 5.9
[0028] Example 2
[0029] like Figure 2 As shown: traditional shredded tobacco can also be mixed with carbonized shredded tobacco or tobacco powder before being rolled into cigarettes, that is, the tobacco segments are composed of a mixture of carbonized shredded tobacco and traditional shredded tobacco, and the mixing ratio of carbonized shredded tobacco to traditional shredded tobacco is 1:3.
