Description

Technical Field

[0001] The present invention relates to the technical field of tobacco scientific research instruments and equipment, and more specifically, to a high-throughput aerosol particle capture device and a capture method. Background Art

[0002] An aerosol refers to a gaseous dispersion system composed of solid or liquid particles suspended in a gas medium. Its essence is a multiphase fluid with a gaseous continuous phase and solid and liquid dispersed phases. The smoke generated by tobacco products (including traditional cigarettes, heated cigarettes, and atomized e-cigarettes) also belongs to the category of aerosols, and it is a process jointly affected by complex dynamic physical, chemical, physiological, and environmental phenomena. The physical states and chemical compositions of aerosols generated by different types of tobacco products are different. To better understand the state and composition of the smoke of tobacco products, it is necessary to capture and analyze the aerosols generated by tobacco products under the condition of simulating the smoking state of consumers.

[0003] A smoking machine is an automated smoking device that simulates the smoking behavior of humans. It can capture aerosol particles in mainstream smoke and is an indispensable device for smoke analysis in the tobacco industry. Currently, the smoking machines in use are mainly divided into two categories according to the types of applicable tobacco products. One is a conventional smoking machine applicable to traditional cigarettes, and the other is an e-cigarette smoking machine applicable to new tobacco products.

[0004] In the prior art, on the one hand, there is a lack of a smoking machine applicable to both traditional cigarettes and new tobacco products (heated cigarettes and atomized e-cigarettes); on the other hand, various smoking machines currently in use usually only include a set of suction units. The ways to shorten the suction time and improve work efficiency are usually achieved by increasing the feeder and discharge bin of the collector, automatic transportation of the collector, and collaborative work of multiple smoking machines.

In this embodiment, through the adjustment of the second position adjuster 73, the cigarette rods 17 in the ignition device 4 are better docked with the corresponding fixed ends A21, so as to better capture aerosol particles, and further improve the convenience of use of the high-throughput aerosol particle capture device.

When the first interface 63 and the second interface 64 are connected, the suction portion 52 sucks the aerosol particles. When the first interface 63 and the second interface 64 are disconnected, the first interface 63 is connected to the third interface 65, and the suction portion 52 evacuates or collects the gas.

Finally, the controller 7 controls the capture device 1 to continuously slide towards the area between the fixing device 2 and the connecting part 51. When the first trap 66 coincides with the axes of the first group of fixing ends A21 and fixing ends B53, the first group of fixing ends A21 and fixing ends B53 and the first trap 66 are sealed and communicated. The controller 7 controls the first lighter 71 to ignite or turn on the switch of the first smoking device 46. The controller 7 controls the suction part 52 to suck to capture the first puff of aerosol particles in the first sample. When the capture is completed, the suction part 52 evacuates or collects the gas. The controller 7 controls the capture device 1 to continue to slide forward. When the second trap coincides with the axes of the first group of fixing ends A21 and fixing ends B53, the first trap 66 also coincides with the axes of the second group of fixing ends A21 and fixing ends B53. The controller 7 controls the first group of fixing ends A21 and fixing ends B53 and the second trap to be sealed and communicated. At this time, the second group of fixing ends A21 and fixing ends B53 and the first trap 66 are also sealed and communicated.

And so on, the Nth puff of aerosol particles of n s samples are all captured by the Nth trap, so as to realize the parallel sequential puff capture of multiple samples, which is applicable to the capture of aerosol particles of traditional cigarettes and new tobacco products, and improves the capture efficiency.
