摘要

The pipe cleaning nozzle structure has rearward directed cleaning nozzle for generating return beam/thrust to pull a to-be-cleaned pipe. A nozzle wheel (32) is moved back and forth on same or different planes by virtue of water pressure, and is pivoted back and forth or rotated. The nozzle wheel is incorporated in the auxiliary cleaning nozzle (36).
