In this application scenario, the cleaning unit 13 is a roller brush. In this mode of use, the nozzles 16 are aligned with the roller brush 13 to spray the discharged liquid 23 onto the surface of the roller brush 13.
The cleaning device works as follows:
1) When the start-up signal of the cleaning equipment is triggered, the main motor 12 and the ground brush motor 11 are powered on to start working, and the ground brush motor 11 drives the rolling brush 13 to rotate.
2) The main motor 12 drives the air inlet unit 1 to generate an air source and output the air source to the air inlet pipeline 3, the air source is discharged through the second air inlet 81, the output port 83, the output pipeline 4 and the nozzle 16 of the three-way pipe 8, and negative pressure is formed in the output pipeline 4.
3) The liquid 23 enters the liquid inlet 82 via the liquid outlet pipe 25 under the action of negative pressure. In the state where the on-off valve 5 is closed, the liquid 23 stops being discharged.
3) The liquid 23 is driven by the negative pressure to be discharged to the surface of the rolling brush 13 through the liquid inlet 82 of the three-way pipe 8, the output port 83 of the three-way pipe 8, the output pipeline 4 and the nozzle 16 in sequence.
4) The bristles of the roller brush 13 bring the discharged liquid 23 toward the floor to wet the floor and wipe the floor, and in the process, the wet roller brush 13 lifts dust from the floor.
5) The main motor 12 is connected with the dust collection channel 17 between the recycling bin 14 and the dust collection opening 15, and dirt on the ground and raised dust are sucked into the recycling bin 14 under the action of negative pressure generated in the dust collection channel 17 by the main motor 12, so that the aim of cleaning the ground is fulfilled.
The cleaning device provided in the third embodiment outputs the liquid 23 through the nozzle 16 at the bottom by the liquid supply device, and the liquid is stable, so that a good cleaning effect is realized.
And, the air inlet unit 1 is driven by the floor brush motor 11 or the main motor 12 of the cleaning equipment to generate an air source, so that the existing power source in the cleaning equipment is utilized to provide power for the air inlet unit 1, or the air outlet through the air outlet of the main motor 12 forms the air source, thereby saving cost and having high reliability.
