Electronic cigarette smoke automatic measuring and collecting system

Abstract

The invention discloses an electronic cigarette smoke automatic measuring and collecting system, which comprises an electronic cigarette, a measuring chamber, a hose, a smoke sampler, a mixing fan, atemperature probe, a heating layer, a heat preservation layer, an outlet adjusting valve, a sucking pump and a control system. The electronic cigarette can be directly connected with an instrument formeasurement, and measurement convenience is achieved; meanwhile, in order to keep physical and chemical properties of measured electronic cigarette smoke and electronic cigarette exhausted smoke consistent and avoid moisture absorption increase and heterogeneous chemical reaction of the electronic cigarette smoke, a constant-temperature component is adopted in the system, and it is ensured that the smoke is consistent with the exhausted state; in addition, the system is designed according to the characteristics of the electronic cigarette smoke and has the specificity characteristic. According to the invention, the electronic cigarette smoke with different particle sizes can be measured and collected, and the distribution characteristics of the physicochemical properties of the electroniccigarette smoke with different particle sizes can be researched scientifically and accurately. Therefore, a theoretical basis can be provided for the design, perfuming and electronic cigarette safetyevaluation of electronic cigarette products, and a reference can also be provided for the safety evaluation of consumers.

Description

technical field [0001] The invention belongs to the field of aerosol measurement, collection and analysis, and in particular relates to an automatic measurement and collection system for electronic cigarette smoke. Background technique [0002] With the in-depth development of my country's smoking ban, more and more people have begun to quit smoking or find other ways to replace cigarette smoking. At present, electronic cigarettes are a relatively mainstream method of quitting smoking or replacing cigarettes. This approach avoids the addictive ingredients of nicotine, a healthy alternative to cigarettes. As e-cigarettes are accepted by more and more consumers, their safety and comfort have gradually attracted attention. Only by clarifying the physical and chemical characteristics of different particle sizes of e-cigarette smoke can we scientifically evaluate the safety and comfort of e-cigarette gas. [0003] However, the existing commercial automatic smoking machines are...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an electronic cigarette for the lack of corresponding instruments and methods in the current research on the physical and chemical properties of electronic cigarette smoke with different particle sizes, resulting in the inability to deeply study the physical and chemical properties of electronic cigarette smoke with different particle sizes. The smoke automatic measurement and collection system can measure and collect e-cigarette smoke with different particle sizes, research scientifically and accurately the distribution characteristics of physical and chemical properties of different particle sizes of e-cigarette smoke, and provide guidance for the design, flavoring, and production of subsequent e-cigarette products. E-cigarette safety evaluation provides theoretical reference
