Abstract
Description
Technical Field
[0001] This utility model relates to the field of flue gas chemical composition analysis technology, and in particular to a portable flue gas collection device. Background Technology
[0002] Aroma compounds in cigarette smoke give it a unique flavor, such as fruity, floral, or roasted notes. These aroma compounds provide smokers with a pleasant olfactory experience, satisfying their preference for fragrance and enhancing the comfort of smoking. They also mask unpleasant odors; tobacco itself contains some impurities and irritants, which aroma compounds can mask, thus improving the sensory experience. The method for detecting aroma compounds in cigarette smoke involves collecting the smoke using a thermal desorption tube and then analyzing it using gas chromatography-mass spectrometry (GC-MS).
[0003] However, the release of aroma in cigarette smoke is affected by factors such as region, altitude, and climate. The aroma compounds produced by the same cigarette can vary greatly depending on the environment in which it is smoked. Therefore, studying the aroma compounds in cigarette smoke under different environments is fundamental to improving cigarette manufacturing processes and enhancing cigarette quality. Developing a portable smoke collection device is the first step in studying the aroma components of cigarette smoke under different conditions. Currently, there are no commercially available portable smoke collection devices in the laboratory. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a portable smoke collection device. This device simulates the act of smoking and uses a thermal desorption tube to collect the smoke generated when a cigarette is inhaled for subsequent analysis.
[0005] The purpose of this invention is to simulate smoking in different environments and collect the smoke for subsequent analysis.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] This utility model discloses a portable smoke collection device, comprising: a first solenoid valve, a labyrinth-type cigarette holder, a main air pipe, branch air pipes, a thermal desorption pipe, a support plate, a suction pipe, a battery, a base, an electric reciprocating telescopic rod, a second solenoid valve, and a controller. The support plate is fixed to one end of the base, one end of the electric reciprocating telescopic rod is fixed to the support plate, and the other end extends into the suction pipe. The battery is fixed to the base and connected to the electric reciprocating telescopic rod. One end of the suction pipe is connected sequentially to the second solenoid valve and the labyrinth-type cigarette holder via the main air pipe. A ring-shaped cigarette holder is connected to a main air pipe between the second solenoid valve and the suction pipe. A branch air pipe is also connected to the main air pipe. A first solenoid valve and a thermal desorption pipe are installed in sequence on the branch air pipe. The thermal desorption pipe is threaded to the branch air pipe. The controller is connected to the first solenoid valve, the second solenoid valve and the electric reciprocating telescopic rod respectively. The cigarette is held on the labyrinth ring-shaped cigarette holder. When the electric reciprocating telescopic rod retracts, it draws the smoke into the suction pipe. When the electric reciprocating telescopic rod extends, it pushes the smoke into the thermal desorption pipe. The components in the smoke are retained on the thermal desorption pipe.
[0008] The portable smoke collection device of this utility model further includes a smoke support, which is mounted on a base between the second solenoid valve and the labyrinth ring cigarette holder to support the main air tube.
[0009] The portable flue gas collection device of this utility model further includes: a first support frame, which is mounted on a base between the first solenoid valve and the thermal desorption tube, for supporting the branch gas pipe.

[0025] Step 4: Properly preserve the thermal desorption tube 16 for subsequent analysis of the composition of the flue gas retained in the thermal desorption tube 16.
