Cigarette stable continuous smoking device with controllable flow

Abstract

A cigarette stable continuous smoking device with controllable flow is characterized by comprising a base plate and a vertical plate fixed on the base plate. A vacuum device is arranged on the base plate, a cigarette holder and a flow detection control part are arranged on the vertical plate, the cigarette holder is communicated with an air inlet of the flow detection control part, and an air outlet of the flow detection control part is communicated with the vacuum device through a connection pipe. Compared with the prior art, the cigarette stable continuous smoking device has the advantages of being capable of providing stable continuous smoking mode, capable of conducting large range adjustment on smoking flow according to experiment research requirements, capable of being used together with a cigarette temperature distribution detection system to detect temperature distribution for continuous smoking of cigarette, simple and convenient to operate, capable of collecting smoke particle phase objects through a Cambridge filter disc and capable of conducting relative detection on the collected particle phase objects.

Description

technical field [0001] The invention belongs to the field of cigarette smoking index detection, and in particular relates to a flow-controllable cigarette stable and continuous smoking device. Background technique [0002] The smoking method of cigarettes is an important factor affecting the smoke components, combustion temperature and other indicators of cigarettes. In order to make the data obtained by various laboratories comparable, GB / T 16450-1996 "Definition and Standards of Smoking Machines for Routine Analysis" "Conditions" stipulates that the standard smoking method is a suction time of 2s and a suction volume of 35ml. Most of the smoking machines on the market are designed around this standard, which brings certain convenience to the detection of cigarette smoking indicators. However, because the adjustable range of the smoking mode of the smoking machine is not flexible enough, it cannot meet the research needs of cigarette smoking indicators, especially the combu...

AI Technical Summary

Problems solved by technology

However, because the adjustable range of the smoking mode of the smoking machine is not flexible enough, it cannot meet the research needs of cigarette smoking indicators, especially the combustion temperature in the following aspects: First, when testing the temperature distribution inside the combustion cone when the cigarette is smoked, In order to compare the differences in the temperature distribution of different cigarettes, it is necessary to keep the cigarettes in a stable and continuous smoking state; secondly, for cigarettes with low ignition tendency, in order to observe the influence of different cigarette flame-retardant belts on the temperature distribution, the cigarettes also need to be in a stable and continuous smoking state. Thirdly, due to certain differences in the static burning rate of different cigarettes, the number of puffs is different, and there may be a high single-puff production of smoke components, and due to the small number of puffs, the test results under standard puffing conditions The total production of smoke components obtained is low, which may be misleading to the research on the formation mechanism of cigarette smoke components
