[0003] The existing cleaning methods include: asking cleaning staff to clean, and the cleaning staff use simple cleaning tools, which are not efficient, the cleaning staff have heavy work, and the labor cost is too high. There are also manually driven sweepers for cleaning, which require operators to sit on the sweeper and manually drive the machine, which is less intelligent; the operators repeat the driving every day, and the work is relatively boring. In addition, with the continuous increase in labor costs, problems such as difficulty in recruiting workers, difficulty in personnel management, and high labor costs are becoming more and more prominent.

[0004] The cleaning patrol robot can automatically clean the ground without manual driving, which can reduce cleaning costs. When the cleaning patrol robot cleans the ground, it needs to spray water and detergent on the ground. When the general cleaning patrol robot is working, the flow rate of the detergent sprayed on the ground and the impact force of the water on the ground will not change. However, if the ground is dirty, the impact force of the water and the flow rate of the detergent are not large, the cleaning patrol robot cannot effectively remove the stains on the ground after passing through the relatively dirty ground.

The lower end of the cleaning disc 27 on the side of the liquid spraying port 26 is provided with an inclined groove 46 parallel to the liquid spraying port 26, and a mounting plate 36 is slidably arranged in the inclined groove 46. The upper end of the inclined groove 46 is inclined toward the liquid spraying port 26, and the cleaning disc 27 rotates in the inclined direction of the upper end of the inclined groove 46.

[0048] A cleaning brush 25 is fixed to the lower end of the mounting plate 36 , and the lower end of the cleaning brush 25 protrudes out of the lower end of the cleaning disc 27 .

[0049] A third cavity 37 is defined in the cleaning disc 27 at the other side of the liquid spraying port 26 . The third cavity 37 communicates with the second cavity 34 and the liquid spraying port 26 .

[0050] After the water pump 24 is started, the water in the water tank can be sprayed onto the ground through the first connecting pipe 29 , the first cavity 33 and the liquid spraying port 26 .

[0051] The cleaning agent in the cleaning agent tank can be discharged after being mixed with the water in the liquid spraying port 26 through the second connecting pipe 30 , the second cavity 34 and the third cavity 37 .

[0052] A flat groove 48 communicating with the liquid spraying port 26 is provided in the cleaning disc 27 below the third cavity 37, and a first baffle 35 is slidably and sealably connected in the flat groove 48, and the first baffle 35 is elastically connected to the cleaning disc 27.

[0053] The ends of the first baffle 35 and the mounting plate 36 on the same side are connected by a drawstring 38. Specifically, the flat groove 48 is connected to the upper end of the inclined groove 46 through a rope groove, and the drawstring 38 is slidably arranged in the rope groove.

[0054] The third cavity 37 includes a vertical section and an inclined section. A vertical groove 49 is opened in the cleaning disc 27 above the inclined section of the third cavity 37. The vertical groove 49 is connected to the inclined section of the third cavity 37. A second baffle 39 is slidably arranged in the vertical groove 49. There is a gap between the lower end of the second baffle 39 and the lower end of the inclined section of the third cavity 37. The ends of the vertical groove 49 in the length direction are connected to the sliding groove 50 in the cleaning disc 27. The lower end of the sliding groove 50 is connected to the flat groove 48. A guide assembly is vertically slidably arranged in the sliding groove 50. The guide assembly is fixedly connected to the second baffle 39, and the guide assembly is fixedly connected to the first baffle 35.

[0055] The guide assembly includes a sliding plate 40 slidably disposed in the sliding groove 50. The sliding plate 40 can slide in the vertical direction of the sliding groove 50, and the sliding plate 40 is fixedly connected to the second baffle 39. A clearance groove 43 is provided in the lower end of the sliding plate 40, and a fixed block 42 is slidably disposed in the clearance groove 43. The fixed block 42 can slide in the length direction of the clearance groove 43, and the lower end of the fixed block 42 is fixedly connected to the upper end of the first baffle 35. Guide grooves 44 are provided on the sliding plates 40 on both sides of the clearance groove 43. The guide grooves 44 are inclined downward toward one end of the liquid spraying port 26. A sliding column 41 is fixed to the fixed block 42 on one side of the guide groove 44, and the sliding column 41 is slidably disposed in the guide groove 44 on one side thereof.

[0056] When the first baffle 35 moves toward the inside of the liquid injection port 26, the fixed block 42 and the sliding column 41 move accordingly. Under the cooperation of the sliding column 41 and the guide groove 44, the second baffle 39 moves upward. After the second baffle 39 moves upward, the gap between the lower end of the second baffle 39 and the lower end of the inclined section of the third cavity 37 increases.

[0057] A squeegee 22 is provided at the rear side of the robot body 1, and the left and right sides of the upper end of the squeegee 22 are rotatably connected with anti-collision wheels 10. The left and right ends of the squeegee 22 are bent forward, and the lower end of the squeegee 22 is in sliding contact with the ground. The upper end of the squeegee 22 is connected to the robot body 1 through an electric telescopic rod. A sewage suction port 23 is provided at the upper end of the squeegee 22, and the sewage suction port 23 is connected to the sewage tank in the robot body 1 through a sewage suction pipe 21. A sewage discharge pipe connected to the sewage tank is fixed on the robot body 1, and the sewage tank is connected to the negative pressure machine in the robot body 1, and the negative pressure machine is electrically connected to the control host and battery in the robot body 1.

[0058] Add water to the water tank through the water inlet 17, and add detergent to the detergent tank through the liquid injection port 18. After the robot body 1 plans the movement path, the control host starts the motor, the drive wheel 9, the water pump 24 and the negative pressure machine. After the drive wheel 9 is started, the robot body 1 moves along the planned path. After the motor is started, the cleaning disc 27 drives the cleaning brush 25 to rotate. After the water pump 24 is started, the water in the water tank is sprayed onto the ground through the first connecting pipe 29, the first cavity 33 and the liquid spray port 26. In the process of the robot body 1 moving along the planned path, the detergent in the detergent tank passes through the second connecting pipe 30, the second cavity 34 and the third cavity 37, and is mixed with the water in the liquid spray port 26 and then discharged.

[0059] The water-retaining rubber strip 8 can prevent the rotating cleaning disc 27 from throwing the mixed liquid of water and cleaning agent discharged from the liquid spraying port 26 to the outside of the robot body 1 .

[0060] When the rotating cleaning disc 27 drives the cleaning brush 25 to rotate, when the cleaning brush 25 rotates and contacts with the relatively clean ground, the friction between the cleaning brush 25 and the relatively clean ground is small, so the cleaning brush 25 and the mounting plate 36 do not move toward the outside of the cleaning disc 27, the size of the gap between the lower end of the second baffle 39 and the lower end of the inclined section of the third cavity 37 remains unchanged, and less cleaning agent passes through the gap between the lower end of the second baffle 39 and the lower end of the inclined section of the third cavity 37. That is, the amount of cleaning agent mixed with the water in the liquid spray port 26 when cleaning the relatively clean ground is small.

[0061] After the cleaning brush 25 comes into contact with the stains attached to the ground, the friction between the cleaning brush 25 and the stains attached to the ground becomes larger, so the cleaning brush 25 rotating with the cleaning disc 27 can move toward the outside of the cleaning disc 27. When the cleaning brush 25 moves toward the outside of the cleaning disc 27, the mounting plate 36 moves accordingly. The mounting plate 36 causes the first baffle 35 to move into the liquid spray port 26 through the pull rope 38 and the slider 45. The spring 47 is stretched. After the first baffle 35 moves into the liquid spray port 26, it can limit the flow of water discharged from the liquid spray port 26, thereby increasing the impact force of the water sprayed from the liquid spray port 26 on the ground.

[0062] When the first baffle 35 moves toward the inside of the liquid spray port 26, the fixed block 42 and the sliding column 41 move accordingly. Under the cooperation of the sliding column 41 and the guide groove 44, the sliding plate 40 and the second baffle 39 move upward. After the second baffle 39 moves upward, the gap between the lower end of the second baffle 39 and the lower end of the inclined section of the third cavity 37 increases, and the flow rate of the cleaning agent discharged from the third cavity 37 increases. Therefore, when cleaning the floor with stains, the impact force of the water discharged from the liquid spray port 26 on the floor can be increased, and the flow rate of the cleaning agent can be increased, which can improve the cleaning efficiency and cleaning effect of the stains on the floor.

[0063] Due to the different friction between the cleaning brush 25 and the clean floor and the floor stained with stains, the displacement of the cleaning brush 25 and the mounting plate 36 when cleaning the floor stained with stains is used as a driving force to adjust the position of the first baffle 35 and the second baffle 39, thereby realizing automatic adjustment of the water spray pressure and the flow rate of the cleaning agent, and the cleaning mode can be adaptively adjusted according to the conditions of the floor.

[0064] During the movement of the robot body 1, the squeegee 22 can collect sewage on the ground, and the negative pressure machine can generate negative pressure in the sewage tank. The sewage collected by the squeegee 22 enters the sewage tank through the sewage suction port 23 and the sewage suction pipe 21.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
