Description

A smoking device and method of using the same

technical field

The present invention relates to the technical field of tobacco, in particular to a smoking device and a method for using the same.

Background technique

Since there are many chemical components in smoke, some of which are harmful to human body, smoke analysis is an important measurement process for safety evaluation and quality evaluation of cigarettes, electronic cigarettes, and heat-not-burn tobacco products. The analytical test standards followed by smoke analysis (such as ISO 4387, HCI, etc.) specify the volume of each puff (puff volume), puff duration and puff flow map (by puff) during puffing. Puffing parameters such as the curve drawn by the airflow velocity versus time).

Different chemical components of flue gas need to be captured by different capture methods and corresponding devices, and different capture devices have different physical properties (such as their own suction resistance, allowable airflow per unit time, etc.) restrictions), different compensation requirements are put forward for the adjustment of the power source of the smoking machine, and the existing smoking devices all use a technical method in which one suction engine corresponds to one or more suction holes, which makes it impossible for a single continuous test process. Adjust the suction engine to meet the needs of capturing different flue gas components. When the laboratory conducts the capture and analysis of different flue gas chemical components, it must be pumped in multiple times, which is inefficient, especially when it needs to be captured by a solid-phase adsorption tube. When there is a gas phase component in the flue gas, the suction resistance of the solid-phase adsorption tube is often high, and the general flow rate of the adsorption tube is limited to less than 100mL/min, while the flow rate specified by the smoking machine standard is often 17.5mL/s or even higher, so The adsorption tube cannot be directly connected in series in the suction and trapped air path of the smoking machine, and the bypass method is used in parallel. For a single adsorption tube, there is a lack of precise synchronous control of the suction parameters such as the suction capacity, so the deviation of the experimental results. Often large, it is difficult to achieve effective data control.
