When in use, the stabilizing rubber column 14 inside the stabilizing cylinder 4 can abut against the surface of the liquid injection pipe 6 under the action of the limiting spring 13, which can play an auxiliary stabilizing effect on the liquid injection pipe 6. When the liquid injection pipe 6 is vibrated, the stabilizing rubber column 14 and the limiting spring 13 can play a buffering role, which can reduce the influence of vibration on the liquid injection pipe 6 and avoid leakage of the liquid injection pipe 6.

[0023] Furthermore, the stabilizing cylinder 4 and the inner groove 12 are of an integrally formed structure.

When in use, the second flange 8 can be connected to the rotating device, and the liquid injection pipe 6 passes through the sealing cover 5 and the stabilizing cylinder 4 and is butted against the inlet pipe 3. When in use, the liquid is transported through the liquid injection pipe 6 and enters the inner rotor pipe 7 in the housing 1 through the inlet pipe 3, and is transported to the rotating device through the inner rotor pipe 7. When in use, the stabilizing rubber column 14 inside the stabilizing cylinder 4 can abut against the surface of the liquid injection pipe 6 under the action of the limiting spring 13, which can play an auxiliary stabilizing effect on the liquid injection pipe 6. When the liquid injection pipe 6 is vibrated, the stabilizing rubber column 14 and the limiting spring 13 can play a buffering role, which can reduce the influence of vibration on the liquid injection pipe 6 and avoid leakage of the liquid injection pipe 6. When in use, the cleaning pipe 9 can be inflated through the micro air pump 15, so that gas enters the housing 1 through the cleaning pipe 9. And when inflating, the micro motor 17 can be started, so that the micro motor 17 drives the spoiler 19 to swing through the shaft rod 18, and the incoming air flow direction can be controlled through the spoiler 19, which is convenient for cleaning the housing 1, and the impurities to be cleaned can be blown out from the observation port 10, which is relatively practical.
