Description
Technical Field
The utility model belongs to the technical field of belong to the cigarette, concretely relates to device of portable heating cigarette paper pipe of inside and outside bidirectional heating.
Background
The cigarette paper tube components have very critical influence on the performance of cigarette ash whiteness, ash column compactness, ash column component structure and the like after the cigarette is combusted, the difference of cigarette ash whiteness after the cigarette is combusted can be obvious when the paper tube components are slightly different, and the difference of cigarette ash performance indirectly influences the smoking experience of smokers, so that the testing of the combustion performance of the paper tube is very necessary, and the components of the paper tube are adjusted in a targeted manner to improve the performance of the cigarette ash.
However, if the cigarette is directly used as a test sample, on one hand, the complexity of the tobacco components has great influence on the ash after the cigarette is burnt, and the test result of the ash whiteness after the cigarette is burnt is not known to be caused by the tobacco components or the paper tube components; on the other hand, even in the same batch of cigarettes, the tobacco components are slightly different from cigarette sample to cigarette sample due to the influence in the tobacco mixing process, which results in poor contrast between the test results for the ash after the combustion of different cigarette samples.
Therefore, it is necessary to examine the combustion performance of the cigarette paper tube alone, but if the mode of igniting the paper tube and then igniting the paper tube is directly used for examination, the test result has no practical reference value at all because: 1. the temperature of a combustion cone when a real cigarette with tobacco is combusted is about 850 ℃, and after the paper tube is ignited, the self-ignition temperature of the paper tube is about 200 ℃, the temperature is far lower than that of the combustion cone when the real cigarette with tobacco is combusted, so that on one hand, the test temperature is inconsistent with the real combustion temperature, more importantly, the paper tube is ignited, black powder is obtained after combustion and is not the same as the color of the ash after the real cigarette is combusted, and no reference significance is provided for investigating the properties of the ash whiteness, the ash column compactness, the ash column component structure and the like after the paper tube is combusted, because the paper tube is combusted and carbonized at the temperature of about 200 ℃. In this regard, it is further conceivable to perform high-temperature carbonization detection of the cigarette paper using a muffle furnace, but the following problems arise: 1. before sample introduction, other devices are needed to remove tobacco and filter tips, and the steps are complicated; 2. the cigarette is directly placed in the container and is detected in the muffle furnace, so that the carbonization state of the paper tube is inconvenient to observe in the detection process, and the normal combustion state of the smoke tube is difficult to maintain after the detection, so that the cigarette is used for detecting relevant indexes such as ash column whiteness, ash column compactness and the like during normal combustion of the cigarette; 3. the muffle furnace needs temperature rise in the process, and the temperature field in the normal carbonization process and carbonization of the cigarettes cannot be well simulated, so that detection results of the whiteness, compactness, component structure and the like of the ash column are greatly different.
In conclusion, the device capable of truly simulating the combustion state of the paper tube in cigarette smoking and the method for developing and testing the combustion performance of the paper tube by using the device are designed, and the device is very important for the research on the combustion performance of the paper tube in the field of cigarettes.
In order to solve the above problems, the utility model is provided.
