With continued reference to fig. 11 and 13, in some embodiments, the liquid receiving mechanism 300 further includes an electromagnetic mounting frame 36 and a guiding frame 37, which are disposed opposite and spaced apart from each other; the guide frame 37 is installed on one side of the support frame 34 departing from the first optical axis 341, a second optical axis 371 extending in the second direction is arranged between the guide frame 37 and the electromagnetic mounting frame 36, the guide frame 37 can move along the axial direction of the second optical axis 371 relative to the electromagnetic mounting frame 36, the liquid receiving box 31 and the guide frame 37 move synchronously, and the second optical axis 371 is used for guiding the movement of the liquid receiving box 31 along the second direction.
Specifically, the electromagnetic mounting frame 36 is used for mounting the electromagnetic driving member 331, and the guiding frame 37 is fixedly disposed on a side of the supporting frame 34 away from the box body frame 312. One end of the second optical axis 371 is mounted to the guide frame 37 and slidably coupled to the guide frame 37. At this time, the actuating rod of the electromagnetic driving element 331 is used to drive the guide frame 37 to move along the second direction so as to move closer to and away from the electromagnetic mounting frame 36, and the guide frame 37 drives the liquid receiving box 31 to move synchronously along the second direction through the supporting frame 34 and the first optical axis 341.

In summary, when the cleaning device provided in an embodiment of the present invention is actually used and a liquid dropping polishing care needs to be performed on a floor, the working head drives the polishing pad 400 and the second pulling plate 322 to move down along the first direction, after the first pulling plate 321 loses a pulling force applied by the second pulling plate 322, the first pulling plate and the liquid receiving box 31 vertically move down under the action of its own gravity, and the first optical axis 341 cooperates with the first guide pillar 342 to guide the downward movement of the liquid receiving box 31. When the box body frame 312 of the liquid receiving box 31 is overlapped on the supporting frame 34, the downward movement of the liquid receiving box 31 is stopped, and the working head continues to move downward until the polishing pad 400 contacts with the ground. Then the electromagnetic driving member 331 is energized to magnetically attract the guiding frame 37 through the actuating rod, so as to drive the guiding frame 37 to move towards the side far away from the polishing pad 400 along the second direction, so that the second optical axis 371 connected to the guiding frame 37 is butted against the corresponding optical axis interface 361 on the electromagnetic mounting frame 36, the guiding frame 37 moves continuously along with the actuating rod, and when the actuating rod reaches the movement limit position or the guiding frame 37 is butted against the electromagnetic mounting frame 36, the liquid receiving box 31 stops moving along the second direction. At this time, the liquid receiving box 31 is completely deviated from the dropping tube 15 so that the liquid feeding tube 11 drops the nursing liquid to the ground through the dropping tube 15. Then, the cleaning apparatus is in a floor care state. When the cleaning device needs to move relative to the floor, the working head drives the polishing pad 400 to slightly move upwards along the first direction, so that the polishing pad 400 is prevented from wearing the floor when the cleaning device moves. At this time, the drip box 31 may be still in a state of being deviated from the drip tube 15 for the next drip care operation. After the floor care operation is completed, the electromagnetic driving member 331 is powered off, the spring of the actuating rod drives the guide frame 37 to move in the second direction in the opposite direction, and the second optical axis 371 is separated from the optical axis interface 361. Then, the working head drives the polishing pad 400 and the second pulling plate 322 to move upwards along the first direction, when the second pulling plate 322 moves upwards and abuts against the first pulling plate 321, the second pulling plate 322 drives the first pulling plate 321 to move upwards synchronously, and the first pulling plate 321 drives the liquid receiving box 31 to move upwards so that the plug 313 in the liquid receiving box 31 can plug the discharge hole of the dropping liquid pipe 15.
