Description

Technical Field

[0001] The present invention relates to a smoke release control device for tobacco products, in particular to a single-suction dual-channel smoke suction and capture method, which can realize the smoke aerosol capture and control of traditional cigarettes, heated cigarettes and other tobacco products. Background Art

[0002] With the continuous development of the tobacco market, tobacco products have shown a diversified development trend. New tobacco products represented by heated cigarettes have become the key development direction of major international tobacco companies and have gradually won the favor of consumers. The generation and delivery mechanism of heated cigarette smoke aerosol is different from that of traditional cigarettes, and there are significant differences in aerosol morphology and composition.

[0003] The smoke extraction and capture devices in the prior art are usually designed as single-channel capture, which means that they can only capture and process one smoke sample at a time. This design simplifies the complexity and operation process of the device, but when a double-sample control test is required, two tests need to be performed separately, which increases the test time and workload. At present, in order to achieve double-sample smoke capture control, two independent single-channel capture devices are usually used to capture two samples respectively, and the comparison is performed in the subsequent data processing and analysis stage. Although this method is feasible, it increases the complexity of the equipment and the difficulty of operation.
