in the present embodiment, the gas pipe 41 is used to convey the gas inside the sampling tube 10 into the sampling head 20 so as to blow off the liquid polyaluminium chloride attached inside the sampling head 20, so that the liquid polyaluminium chloride dropped from the sampling head 20 of the sampling tube 10 affects the detection environment when the sampling tube 10 in the sampling device is moved;
further, the gas pipe 41 prevents the gas or liquid from flowing back through the check valve 42 to reduce the interference to the sampling of the cartridge 10.
