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 device for collecting total particulate matter in flue gas. Background Technology
[0002] The determination of total particulate matter (TPM) in cigarette smoke is of great significance. It is a key indicator for evaluating cigarette safety because it contains various harmful components, such as tar. Tar is a substance that can harm human health, and the degree of harm from cigarettes can be assessed by measuring TPM.
[0003] However, the determination of total particulate matter (TPM) in cigarette smoke is affected by factors such as region, altitude, and climate. The TPM results for the same cigarette can vary significantly depending on the environment. Therefore, studying TPM in cigarette smoke under different conditions is fundamental to cigarette smoking safety, and developing a portable TPM collection device is the first step in researching TPM content in cigarette smoke under varying conditions. Currently, all existing TPM collection devices are large-scale devices; there are no commercially available portable TPM collection devices. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention provides a portable device for capturing total particulate matter in cigarette smoke. This device simulates the act of smoking and uses a filter-type smoke collector to capture the smoke generated when a cigarette is inhaled for subsequent analysis.
[0005] The purpose of this application is to simulate smoking in different environments and collect total particulate matter in 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 device for collecting total particulate matter in flue gas, comprising: a first one-way valve, a labyrinth ring cigarette holder, a main air pipe, branch air pipes, a filter-type flue gas collector, a support plate, a suction tube, a battery, a base, an electrically reciprocating telescopic rod, and a second one-way valve. The support plate is fixed to one end of the base, one end of the electrically reciprocating telescopic rod is fixed to the support plate, and the other end extends into the suction tube. The battery is fixed to the base and connected to the electrically reciprocating telescopic rod. One end of the suction tube is connected to the main air pipe.

A branch air tube is also connected to the main air tube between the second one-way valve and the suction tube. The first one-way valve and the filter-type smoke collector are installed in sequence on the branch air tube. The cigarette is held in the labyrinth ring cigarette holder. When the electric reciprocating telescopic rod retracts, it draws the smoke into the suction tube. When the electric reciprocating telescopic rod extends, it pushes the smoke into the filter-type smoke collector. The filter paper installed in the filter-type smoke collector traps the components in the smoke.

The support plate 7 is fixed to one end of the base 10, and one end of the electrically reciprocating telescopic rod 11 is fixed to the support plate 7, with the other end extending into the suction tube 8, which has a capacity greater than 55ml. The battery 9 is fixed to the base 10 and connected to the electrically reciprocating telescopic rod 11. One end of the suction tube 8 is connected sequentially to the second one-way valve 13 and the labyrinth ring cigarette holder 2 via the main air pipe 4. A branch air pipe 5 is also connected to the main air pipe 4 between the second one-way valve 13 and the suction tube 8. A first one-way valve 1 and a filter-type smoke collector 16 are sequentially mounted on the branch air pipe 5. A cigarette holder 3 is mounted on the base 10 between the second one-way valve 13 and the labyrinth ring cigarette holder 2 to support the main air pipe 4.
