Description

Technical Field

[0001] The present invention relates to the technical field of tobacco analysis, and more specifically to a portable cigarette draw resistance dynamic flow detection device. Background Art

[0002] Cigarettes, as a smoking commodity, have a draw resistance during smoking, that is, the resistance felt by smokers due to the filling of tobacco in the pipe during smoking. In the tobacco industry, this is called cigarette draw resistance. In order to make the draw resistance of cigarettes of the same brand as consistent as possible, that is, homogenization processing, tobacco industry practitioners will regularly monitor the draw resistance of cigarettes and control it within a certain range.

[0003] However, tobacco practitioners usually use the "static" monitoring method to monitor the draw resistance of cigarettes on a daily basis, that is, to conduct quantitative detection of the draw resistance when the cigarette is not burned. However, as a smoking product that needs to be burned, the "dynamic changes" of the draw resistance of cigarettes during the burning process make the "static" draw resistance data unable to truly and objectively reflect the consumers' feelings of draw resistance during the smoking process. Therefore, developing new dynamic flow detection equipment or methods for cigarette draw resistance is an inevitable choice and a necessary path for the tobacco industry to get close to the real needs of consumers during the smoking process.

[0039] The smoke inlet connector 2 can be adapted to different types of rotary smoking machines according to the detection requirements to perform dynamic inhalation resistance flow detection of cigarettes of different specifications. Specifically, the portable cigarette inhalation resistance dynamic flow detection device of the present invention is suitable for the detection process of dynamic inhalation resistance of cigarettes of rotary smoking machines as follows:

The dynamic draw resistance flow detection position is in the first grid after the turntable smoking machine completes spotting of the first cigarette, that is, the smoking machine completes a cigarette smoking at the first grid position. The smoke generated when each cigarette and each puff is completed at this position passes through the external smoke duct and enters the detection device for detection, and the record is stored in the memory in the PCB acquisition control board 8.

[0042] Step 3: After the test is completed, connect the Type-C digital acquisition charging interface 9 to the computer's digital acquisition analysis software to upload the dynamic suction resistance flow, flow rate, ambient temperature, pressure and other data recorded during the puffing process, and correspondingly record the cigarette data, time data, number of puffs and other data.

The portable cigarette draw resistance dynamic flow rate detection device of the present invention is suitable for the rapid detection of the dynamic draw resistance of a handheld single cigarette. The detection process is as follows:

[0044] Step 1: Accuracy calibration of portable dynamic flow detection device for cigarette draw resistance: Use a stable suction method (constant suction flow rate) to measure the draw resistance of cigarettes in the unlit state. The result is fitted with the static draw resistance of cigarettes measured by standard measuring instruments in the industry.

[0045] Step 2: Light the test cigarette and take each puff manually through the suction nozzle 15. The cigarette holder 16 can be adapted to cigarettes of different specifications. After each puff of the cigarette is completed, the smoke generated during each puff passes through the cigarette holder 16, passes through the external smoke duct, and then enters the detection device for detection and is recorded and stored in the memory in the PCB acquisition control board 8.
