A cigarette smoke collection device, smoking machine and collection method

Abstract

The invention provides a smoke trapping device for cigarette products, a smoking machine and a trapping method. The flue gas trapping device comprises a vacuum sampling and collecting device, a first one-way valve, a second one-way valve, a three-way, a heatable A suction syringe, the cigarette product and the heatable suction needle are linearly connected at both ends of the three-way valve. The other end of the three-way is connected with a one-way valve and a vacuum sampling collection device. After triggering the ignition of the cigarette product, the smoke enters the heatable suction syringe through the one-way valve and the three-way, and then the smoke in the suction syringe is discharged. Push back into a cooled vacuum sampling collection device. The application also discloses a smoking machine for cigarette products, which at least includes the above-mentioned smoke trapping device. The present invention provides a smoke trapping device for cigarette products and a smoking machine, which have a simple structure and simultaneously collect mainstream smoke from cigarette products. For the gas phase and particulate matter, the flue gas is collected directly and the loss is small, which can improve the accuracy of the later analysis data results.

Description

technical field [0001] The present invention relates to the technical field of smoking machines, in particular to a smoke collecting device for cigarette products, a smoking machine and a collecting method. Background technique [0002] Mainstream cigarette smoke consumers directly smoke imported ones, which are directly linked to sensory experience and experience. Therefore, the analysis of mainstream smoke is very important. The capture of cigarette smoke is the basis and key link of smoke analysis. Mainstream smoke is divided into particulate matter and gaseous matter. The proportion of particulate matter in traditional cigarette smoke is large. Cambridge filters are often used to capture particulate matter and the solution absorbs gaseous components, which is not only complicated in procedures, but also in Cambridge filter. After collection, a series of processes such as aging treatment are required, which will inevitably lead to losses. [0003] In recent years, with t...

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
