Direct discharge of waste gas will pollute the surrounding environment, and long-term breathing of waste gas will affect human health. In order to avoid the impact of waste gas on the living environment, the waste gas needs to be treated so that it meets qualified emission standards. Factories need to regularly sample and test the discharged waste gas, so as to adjust the treatment of the waste gas so that it meets qualified emission standards.

[0016] In summary, the present application includes at least one of the following beneficial technical effects: 1. By providing an air intake assembly and an exhaust pipe, a one-way valve is installed in the exhaust pipe. When the piston is pulled outward, negative pressure is formed in the collection tube, so that the sealing cover in the air intake assembly can be sucked inward, and the exhaust gas enters the collection tube from the gap between the sealing cover and the shell until the air pressure is balanced. In order to ensure the accuracy of collecting exhaust gas, the piston is pushed forward again, and the sealing cover is tightened against the shell under the action of elastic force to form a seal. The gas in the collection tube can only be discharged from the exhaust pipe. Repeating the above action several times can exhaust the gas in the collection tube, avoid the original gas in the collection tube from polluting the exhaust gas, and the collection effect is better; 2.
