[0045] In this embodiment, the pipe cleaning machine is connected to a PLC (Programmable Logic Controller) controller, and the user can control the valves, circulation pumps and other electrical equipment in the pipe cleaning machine through the PLC controller; after the pipe to be cleaned is connected to the first circulation pipe 2, it becomes a part of the first circulation pipe 2, so that the first circulation pipe 2 forms a closed loop, and the water in the water reservoir 1 is pumped into the first circulation pipe 2, and the water cleans the pipe to be cleaned when passing through it, and then returns to the water reservoir 1; the water reservoir 1 is a rectangular water storage container, and its volume is determined according to the actual cleaning needs of the user, which is not limited here; in this embodiment, the water quality monitoring component can monitor the water quality of the water in the water reservoir in real time.

[0064] As a preferred embodiment, the pipeline cleaning machine comprises:

[0065] The air conduction component is connected to the first circulation pipe 2 and is used to transmit air to the first circulation pipe to dry the pipeline to be cleaned on the specimen installation position 22.
