This technical solution uses the threaded barrel, the screw, the pull rod, the mounting barrel and the bristles so that when it is necessary to clean the inside of the sampling barrel, the screw can be separated from the threaded barrel by rotating the pull rod, and then a cleaning liquid is added to the inside of the sampling barrel, and then the screw is connected to the threaded barrel. After the connection is completed, it continues to rotate so that the bristles on the mounting barrel can clean the inside of the sampling barrel, and the mounting barrel can be rotated and disassembled to the pull rod for replacement to prevent the bristles from being contaminated. Through the sampling nozzle and the hose, the sampling nozzle can be rotated to disassemble it for cleaning separately during cleaning, making cleaning more convenient, and the setting of the hose increases the sampling distance of the sampling nozzle.
