Problems solved by technology

However, there are few researches on the shape of cigarette combustion cone and its carbonization circle at present, and the test methods for the characteristics of combustion cone and carbonization circle are also very immature. Therefore, there is an urgent need for a convenient, intuitive and fast cigarette combustion cone and Carbonization circle test method, through the analysis and processing of measurement data, so as to improve the combustion matching performance of shredded tobacco and cigarette paper

Embodiment 1

[0021] Take a cigarette, mark a line 2cm, 3cm, and 4cm away from the cut tobacco end of the cigarette, place the cigarette on a horizontal support, use the ignition device to ignite the cigarette, and ensure that the surrounding airflow environment is stable and there is no convection. When the cigarette burns past the 2cm mark, gently flick off the cigarette ash by hand. Measure the distance L from the top of the cigarette burning cone to the carbonization ring with a special measuring device for the burning cone 1 . When the cigarette burns to the 3cm mark, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 2 . When the cigarette burns to the 4cm mark, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 3 . Take the average value L of three measurements (L=(L 1 +L 2 +L 3 ) / 3), as the combustion cone length value of this cigarette.

Embodiment 2

[0023] Take a cigarette, place the cigarette on a horizontal support, use the ignition device to ignite the cigarette, and ensure that the surrounding airflow environment is stable and there is no convective wind. When the cigarette burns for 60 seconds, use the spring to gently flick off the cigarette ash. Use a straightedge to measure the distance L from the top of the cigarette burning cone to the carbonization ring 1 . When the cigarette burns for 80 seconds, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 2 . When the cigarette burns for 100s, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 3 . Take the average value L of three measurements (L=(L 1 +L 2 +L 3 ) / 3), as the combustion cone length value of this cigarette.

Embodiment 3

[0025] Take a cigarette, mark a line 2cm, 3cm, and 4cm away from the cut tobacco end of the cigarette, place the cigarette on a horizontal support, use the ignition device to ignite the cigarette, and ensure that the surrounding airflow environment is stable and there is no convection. When the cigarette burns past the 2cm mark, use the spring to gently flick off the ash from the cigarette. Use the photo acquisition device to take pictures, and then calculate the distance L from the top of the cigarette burning cone to the carbonization circle through the image analysis software 1 . When the cigarette burns to the 3cm mark, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 2 . When the cigarette burns to the 4cm mark, repeat the above steps to measure the distance L from the top of the cigarette burning cone to the carbonization ring 3 . Take the average value L of three measurements (L=(L 1 +L 2 +L 3 )...

Abstract

The invention relates to a method for measuring dimension of a cigarette burning cone shape, which comprises the following steps: 1) taking a cigarette, and respectively marking M1-n at different distances from a lit end of the cigarette; 2) putting the cigarette on a horizontal bracket, lighting the cigarette, and ensuring the ambient air flow environment to be stable without convective wind interference; 3) when the cigarette burns for a certain time Sn or to the mark Mn, flicking off the cigarette ash; 4) measuring the distance Ln from a burning conic node of the cigarette to a carburized circle; and 5) taking the average value L = (L1 + L2 +... + Ln) / n measured for n times as the length of the burning cone of the cigarettes. The measuring method of the invention has the following characteristics and advantages of visual method, simple operation, quickness and easy popularization and easy promotion. The measuring method can be used for characterizing the burning matching performance of tobacco shreds and cigarette paper when the cigarette burns, on the one hand, the method can ensure the cigarette to have a good burning appearance when the cigarette burns, and on the other hand, can reduce the miscellaneous gas or harmful gas generated by incomplete burning of the cigarette paper or the cigarette.

Description

technical field [0001] The invention relates to a method for measuring the shape and size of a cigarette burning cone, in particular to a method for measuring the length of a cigarette burning cone and a method for testing the width of a carbonization circle on the burning cone, which are used to characterize the matching performance of shredded tobacco and cigarette paper burning during cigarette burning. Background technique [0002] The burning of cigarettes is a very complex physical and chemical process. The combustion of cigarettes and the formation of smoke is a complex chemical system. According to scientific research, in the process of lighting a cigarette, when the temperature rises to 300°C, the volatile components in the shredded tobacco begin to volatilize and form smoke; when the temperature rises to 450°C, the shredded tobacco begins to coke; when the temperature rises to 600°C , the cigarette is lit and begins to burn. [0003] There are two forms of cigare...
