The cleaning head 3 further comprises a wiping layer 11 arranged outside the swivel tube 9, the wiping layer 11 being arranged to wipe the wall of the transfer conduit 12, and when the opening 7 and the outlet opening 8 are in communication, cleaning liquid flows out of the opening 7 wetting the wiping layer 11.

The number of the liquid outlet holes 8 is the same as that of the open holes 7, and the liquid outlet holes 8 and the open holes 7 are uniformly distributed, so that the cleaning liquid can flow out of the open holes 7 to uniformly wet the wiping layer 11.

The rotary switch 4 is rotationally connected with the connecting pipe 6, and after the connecting pipe 6 is detached from the pipe body 1, the rotary switch 4 is detached, so that the cleaning head 3 can be directly detached for destroying after use to prevent bacterial and virus breeding.

In this embodiment, the diameters of the liquid outlet hole 8 and the opening hole 7 are set smaller, so that the outflow speed of the cleaning liquid is not too high, and the movement speed of the piston 5 pushed by the compressed air is slower, or the movement speed of the piston 5 pushed by the spring is slower. In the third embodiment, the control device 21 controls the driving device 18 to drive the piston 5 to move, so that the outflow dose of the cleaning liquid can be precisely controlled.

Further, the rotary switch 4 further comprises a rubber head 10 arranged at the end of the rotary tube 9, and the rubber head 10 is used for injecting liquid into the liquid storage cavity 2 by penetrating the connecting tube 6 through a liquid injection needle of the liquid injection device 13.
