[0030] Working principle: when in use, open the sealing cover, and then connect the external water pipe with the water injection pipe. After the connection, the external water source will enter the inner cavity of the reactor body 1 to play a cleaning role. At this time, the servo motor 5 can be operated. When the servo motor 5 is running, it will drive the rotating shaft 6 to rotate. When the rotating shaft 6 rotates, it will drive the convex column 76 to rotate. When the convex column 76 rotates, it will drive the turntable 72 to rotate through the circular column 71. When the turntable 72 rotates, it will drive the scraper A75 to rotate through the connecting rod 73 and the n-shaped plate 74.

When the L-shaped connecting plate 863 rotates, it drives the squeezing ball 78 to rotate through the cross bar. When the squeezing ball 78 rotates, it will continuously rotate with the trapezoidal block 77, and will also squeeze it to move downward continuously, thereby driving the circular column 71 to rotate. The outer side of the convex column 76 slides up and down, and the setting of the return spring A763 can make the circular column 71 recover after being squeezed, that is, the scraper A75 can also shake up and down back and forth while rotating, thereby improving the scraping effect.
