After the sampling is completed, the air inlet channel cannot be closed, so that subsequent air enters the sampling box, affecting the sampling results. Summary of the invention

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The present application sets an electric cylinder. The operator turns on the electric cylinder, so that the electric cylinder drives the piston rod and the piston plate to slide in the inner cavity of the collection tube to discharge the residual gas in the collection tube. The piston rod drives the wedge plate and the sealing device to open, so that the outside gas enters the collection tube through the air inlet pipe. Then the electric cylinder drives the piston rod to contract, and the piston rod drives the piston plate to slide. After the collection tube sucks the outside gas, the sealing device can block the air inlet pipe to prevent the outside gas from continuously entering the collection tube and affecting the results of air treatment sampling.

[0016] 2. This application sets a conductive contact. When the electric cylinder retracts the piston rod, the piston rod drives the piston plate to slide in the inner cavity of the collecting cylinder until the conductive contact on one side of the piston plate is connected to the conductive contact in the collecting cylinder. The conductive contact sends an electrical signal, so that the controller controls the electric cylinder to close, thereby avoiding excessive contraction of the piston rod, which may cause damage to the piston plate and the collecting cylinder.
