Constant flow smoking machine

Abstract

A constant flow rate smoking machine, comprising a cigarette holder arranged on the upper panel, a total particulate matter trap connected to the mainstream smoke pipe at the rear end of the holder, a reversing valve, a gas flow detection and control device, It is composed of a vacuum pump and a mainstream smoke collection port. A plexiglass cover for collecting side flow smoke is installed on the upper panel, and a side flow smoke outlet is opened on the upper panel inside the glass cover, and a side flow smoke outlet is added to the outlet. The flue gas filter is in communication with the side flow flue gas fan and the side flow flue gas collection port; the total particulate matter trap is installed on the upper panel, and the reversing valve, gas flow detection control device, and vacuum pump are arranged on the bottom plate. The valve is provided with a purge gas path interface. The invention can stabilize the suction flow rate of cigarettes and realize the setting and control of constant flow rate; it can clean the smoke channel in time, which greatly reduces the influence on the experimental results; and it can expand the collection of mainstream smoke and side smoke when cigarettes are burning. Flow flue gas, realize the analysis and detection of main and side flow flue gas components.

Description

technical field [0001] The invention belongs to the field of cigarette burning and smoking index detection instruments, and in particular relates to a constant flow rate smoking machine with controllable suction capacity. Background technique [0002] Various smoking machines are generally used in the detection of cigarette smoke components, combustion temperature and other indicators in the laboratory. In order to make the test data obtained between laboratories comparable, GB / T16450-1996 "Definition and Standard Conditions of Smoking Machines for Routine Analysis" stipulates that the standard smoking method is a suction time of 2s and a suction interval of 58s. The suction capacity is 35ml, and most smoking machines currently in use are designed around this standard. [0003] When conducting research on cigarette smoking indicators, especially cigarette combustion temperature and smoke component formation mechanism, due to the inflexible adjustable range of the smoking mo...

Problems solved by technology

Although the device solves the problem of continuous smoking, the degree of automation of the device is not high; the flue gas channel cannot be cleaned in time, which may cause poor repeatability of the experimental results; affected by the surrounding environment
