The device is characterized by being used for trapping components in a method for measuring the flavor components in cigarette smoke, wherein the cigarette has a functional section, the trapping device comprises a Cambridge filter catcher, a suction engine and a gas sampling bag, the Cambridge filter catcher is communicated with the functional section of the cigarette to be measured, the suction engine is respectively communicated with the Cambridge filter catcher and the gas sampling bag, smoke in the heated cigarette flows out of the functional section of the cigarette through the power of the suction engine, passes through the Cambridge filter catcher and then flows into the gas sampling bag to be collected, and therefore smoke particle phase objects and smoke gas phase objects are respectively obtained in the Cambridge filter catcher and the gas sampling bag.

2. The cigarette smoke aroma component trapping device according to claim 1, further comprising an aroma component absorber located between said cambridge filter trap and said gas sampling bag in the smoke flow direction for absorbing aroma components in smoke flowing out of said cambridge filter trap.

3. The apparatus according to claim 2, wherein a smoke circulation circuit is formed between the gas sampling bag and the flavor absorber, so that after the smoking is finished, the smoke in the gas sampling bag is driven by the smoking engine to circulate between the flavor absorber and the gas sampling bag for a plurality of times.

4. The apparatus for trapping flavor components in cigarette smoke according to claim 3, further comprising a switching valve, a first channel, a second channel and a third channel, wherein the first channel is used for communicating the flavor component absorber, the suction engine and the gas sampling bag and is connected with the switching valve, the second channel is used for communicating the Cambridge filter trap and the switching valve, the third channel is used for communicating the gas sampling bag and the switching valve, and the switching valve is used for controlling the opening and closing of the first channel and the second channel and the communication between the first channel and the third channel and controlling the closing of the communication between the second channel and the third channel.

5. The apparatus according to claim 4, wherein said trapping device further comprises a first valve disposed on said gas sampling bag and in communication with said third passageway.

6. The apparatus for trapping aroma components in cigarette smoke according to any one of claims 2 to 5, wherein said aroma component absorber is filled with a solid absorbing material for passing said smoke.

7. The apparatus for trapping aroma components in cigarette smoke according to any one of claims 2 to 5, wherein said aroma component absorber contains an extracting agent for passing said smoke.

8. The apparatus for trapping aroma components in cigarette smoke according to claim 7, wherein said aroma component absorber is two or more serially connected absorption bottles, and said extraction agent is contained in said absorption bottles.

9. The apparatus for trapping aromatic components in cigarette smoke according to any one of claims 1 to 5, further comprising an injector for communicating with the gas sampling bag after the gas sampling bag finishes the collection of the smoke, and injecting an extracting agent into the gas sampling bag to obtain a gas phase extract.

10. The apparatus for trapping flavor components in cigarette smoke according to any one of claims 1 to 5, wherein said functional segment is a filter.
