[0025] According to the above technical solution, the vacuum fan 402 sucks in the exhaust gas through the intake pipe 401, discharges it into the inlet pipe 404 through the outlet pipe 403 and enters the collecting pipe 408. The air pressure pushes the piston plate 409 in the collecting pipe 408 backward through the balance hole 410 to maintain the air pressure balance. When the movement stops, the gas enters the air bag 407 along the vent 406, and continuously expands the air bag 407 in the pipe cover 405 to press against the inlet pipe 404.

[0026] Specifically, the auxiliary detection mechanism 5 includes a cassette 501, a card board 502, a charging port 503, a battery 504 and a hatch 505. The cassette 501 is fixedly connected to the right side surface of the fuselage 1, and the front end of the cassette 501 is movably installed on the inner surface of the card board 502. The front surface of the card board 502 is provided with a slide groove buckle corresponding to the front surface of the cassette 501. The charging port 503 is fixedly installed on the upper surface of the card board 502, and the battery 504 is fixedly installed on the rear surface of the charging port 503. The battery 504 is connected to the vacuum pump 402 through electric wires, and the hatch 505 is movably installed on the lower side of the front surface of the fuselage 1.

[0027] According to the above scheme, the air intake pipe 401 is hung down, and the cassette 501 is slid into the card board 502 along the surface of the air intake pipe 401. Then the hatch 505 is opened, the inlet pipe 404 is pulled out, and the gas in the collection pipe 408 is sent to a professional laboratory to detect the exhaust gas in the collection pipe 408. When the battery 504 is out of power, it can be charged directly through the charging port 503, which is more convenient for detection.

[0028] Working principle: When it is necessary to collect the exhaust gas, the operator can carry the fuselage 1 through the shoulder strap 2, and then move it to the position where the exhaust gas needs to be detected, and then start the vacuum pump 402. Then the operator holds the suction pipe 401 and aligns it with the corresponding position. The vacuum pump 402 will suck the exhaust gas through the suction pipe 401, and discharge it through the outlet pipe 403, and enter the collection pipe 408 along the inlet pipe 404. At this time, the air pressure will push the piston plate 409 in the collection pipe 408 backwards, and the piston plate 409 will discharge the air behind the collection pipe 408 through the balance hole 410 to achieve the effect of balancing the air pressure. Then, when the piston plate 409 reaches the arc-shaped top at the bottom of the collection pipe 408, it stops moving. At this time, the excess gas will flow out along the vent 4 06 enters the airbag 407, and continuously expands the airbag 407 in the tube cover 405 until the airbag 407 in the tube cover 405 presses against the inlet pipe 404, then closes the vacuum pump 402, hangs down the air intake pipe 401, slides the cassette 501 into the card plate 502 along the surface of the air intake pipe 401, then opens the hatch 505, and pulls out the inlet pipe 404. At this time, the airbag 407 will squeeze the cavity toward the center due to the air pressure, and then the collection pipe 408 can be taken out, and the gas in the collection pipe 408 can be sent to a professional laboratory to detect the exhaust gas in the collection pipe 408. When the battery 504 is out of power, it can be directly charged through the charging port 503, which is more convenient for detection. The heat dissipation hole 3 can cool the vacuum pump 402 in operation.

[0029] In order to enable the vacuum fan 402 to extract air, the rated power of the vacuum fan 402 shall not be less than 600W, so that the vacuum fan 402 can suck the exhaust gas into the collecting pipe 408 through the suction pipe 401.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
