[0026] like Figures 1 to 7 As shown, in this embodiment, the utility model includes a diverter body 1, in which a plurality of air intake pipes 2 and a plurality of diverter units are arranged, and the plurality of air intake pipes 2 are respectively connected with the plurality of diverter units, and the air intake pipe 2 has an air intake pipe outlet 3 and an air intake pipe inlet 5 exposed outside the diverter body 1, and the diverter unit includes a plurality of diverter pipes 6, and the plurality of diverter pipes 6 all have diverter air intakes 4 with the same pipe diameter and a diverter air outlet 7 exposed outside the diverter body 1, and the plurality of diverter air intakes 4 are closely arranged around the air intake pipe outlet 3, and are all connected with the air intake pipe outlet 3. Specifically, since the plurality of diverter air intakes 4 with the same pipe diameter are closely arranged around the air intake pipe outlet 3, and are all connected with the air intake pipe outlet 3, the gas in the air intake pipe 2 can be evenly distributed to the plurality of diverter pipes 6 with equal resistance, and further multiple olfactory identification personnel can perform olfactory identification at the same time.

[0027] For the sake of convenience, it is taken that the number of the air intake pipeline 2 and the flow splitting unit are both three, and the flow splitting unit has six flow splitting pipes 6, one of the air intake pipelines 2 is used to input the sample gas, and the other two air intake pipelines 2 are used to input the clean air. During the olfactory identification experiment, it can be ensured that the one-way sample gas and two-way clean air input are evenly split into six-way sample gas and twelve-way clean air, a total of eighteen ways, and can reach the split outlet 7 at the same time, so that six olfactory identification personnel can perform olfactory identification at the same time.

[0028] With respect to the deficiencies of the prior art, in the utility model, by providing an air intake pipeline 2 and a diversion unit in the diversion body 1, the sample gas and the clean air can be evenly distributed to multiple olfactory personnel for simultaneous olfactory identification, so that the gas volume of each path is evenly distributed, which effectively improves the accuracy and stability of gas distribution; moreover, the integrated gas diversion device of the utility model can simplify parts, integrate the complex pipelines inside the instrument, solve the problem of decentralized connection of the olfactory experiment pipelines, and make the utility model have the advantages of compact structure, high gas distribution accuracy and good gas distribution stability.

Since the input gas is high-pressure gas, even if the lengths of the plurality of diversion pipes 6 are different, the plurality of diversion outlets 7 can also discharge gas almost simultaneously, so as to provide multiple olfactory identification personnel with the gas for simultaneous olfactory identification.

[0030] In some embodiments, the number of the air intake pipeline 2 and the number of the flow diversion units are both three.
