Collection and capture device for mainstream and sidestream smoke of cigarette

Abstract

A collection and capture device for mainstream and sidestream smoke of cigarette comprises a cigarette clamping mechanism, a mainstream smoke passage, a sidestream smoke passage, a vacuum pump, a control system and an exhaust system. The cigarette clamping mechanism comprises a manual lip, a mainstream support column and an ash receiving tray, wherein the manual lip is used for fixing the cigarette and inhaling the mainstream smoke and has the rear end used for connecting with the mainstream smoke passage; and the ash receiving tray is placed blow the cigarette by a certain distance. The mainstream smoke passage is composed of a filter assembly, a mainstream absorption bottle, a gas flowmeter, a vacuum pump and a controller. The sidestream smoke passage is composed of a fishtail cover, a filter assembly, a sidestream absorption bottle, a gas flowmeter, a vacuum pump and a controller, wherein the position of the fishtail cover supported on the sidestream support column is adjustable. All the parts of the mainstream smoke passage and the sidestream smoke passage are connected through rubber tubes; the control end of the vacuum pump is connected with the controller and controlled by the controller. The controller is composed of a computer, a USB interface, a relay and a power supply.

Description

technical field [0001] The invention relates to a cigarette smoke collecting and capturing device, in particular to a program-controlled system capable of simulating a human smoking process to collect, capture and detect mainstream and sidestream smoke. Background technique [0002] The impact of smoking on human health has always been a hot issue concerned by experts and scholars from all over the world. At present, the analysis of flue gas mainly includes mainstream flue gas analysis and sidestream flue gas analysis. Most of the research institutions at home and abroad use some relatively simple instruments made by themselves for research and analysis. There is no uniform standard, and the accuracy of measurement and analysis is not high. Very high, and are basically manual equipment, so the efficiency is low and the function is single. For example, Ou Lingcheng's "portable intelligent smoking simulation device" (ZL 200320115003.7) uses a solenoid valve to control the ope...
