Smoke trapping device, smoking machine and trapping method for cigarette product

Abstract

The invention provides a smoke trapping device, a smoking machine and a trapping method for a cigarette product. The smoke trapping device comprises vacuum sample introduction and collection devices,a first one-way valve, a second one-way valve, a tee joint and a heatable suction needle cylinder, wherein the cigarette product and the heatable suction needle cylinder are linearly connected to twoends of the tee joint; the other end of the tee joint is connected with the one-way valve and one corresponding vacuum sample introduction and collection device; and after the cigarette product is triggered to be lighted, smoke enters the heatable suction needle cylinder through the one-way valve and the tee joint, and then, smoke in the suction needle cylinder is backwards pushed into one cooledvacuum sample introduction and collection device. The invention also discloses a smoking machine for the cigarette product. The smoking machine at least comprises the smoke trapping device. The provided smoke trapping device and smoking machine for the cigarette product are simple in structure; and by collecting gas-phase matter and granule-phase matter in main stream smoke of the cigarette product simultaneously, smoke collection is direct and low in loss, and the later analysis accuracy of data results can be improved.

Description

technical field [0001] The invention relates to the technical field of smoking machines, in particular to a cigarette product smoke collection device, a smoking machine and a collection method. Background technique [0002] Consumers directly smoke imported cigarette mainstream smoke, which is directly linked to sensory experience and experience. Therefore, the analysis of mainstream smoke is very important, and the capture of cigarette smoke is the basis and key link of smoke analysis. Mainstream smoke is divided into particulate phase and gaseous phase. The proportion of particulate phase in traditional cigarette smoke is large. Cambridge filters are often used to capture particulate phase components, and the method of absorbing gas phase components by solution is not only complicated, but also Cambridge filter. After the film is collected, a series of processes such as aging treatment are required, and losses will inevitably be caused during the treatment process. [000...

AI Technical Summary

Problems solved by technology

However, since new cigarettes are different from traditional cigarettes in that their heating temperature is less than 400°C, the particulate phase components and gas phase components in the mainstream smoke become less, especially the proportion of particulate phase substances decreases and the proportion of gas phase substances increases, so only the particulate phase components The greater the difference with the full components of mainstream smoke, if you want to measure the components of the whole smoke, you must separate the gas phase and particle phase components to simultaneously capture and measure them separately, which will inevitably lead to an increase in experimental steps and the increase of experimental error, therefore, there is a need for a method of capturing the whole smoke of cigarettes, which can realize the one-time capture of the particle phase components and gas phase components of cigarettes
