Definitions

  • the present disclosure relates to the technical field of cleaning equipment, in particular to a sweeping robot and a water tank for a sweeping robot.
  • Sweeping robots are self-cleaning devices that reduce the pressure on people to clean. Sweeping robots generally use the structure of roller brushes, rollers, sinks, and water tanks. Clean water is provided to the roller from one end of the water tank, and sewage discharged from the roller is sucked into the sewage tank through negative pressure. The clean water tank and the sewage tank are separated, which greatly diminish practical spacer of the clean equipment.
  • a water tank for a cleaning robot comprising: a water tank body.
  • the water tank body has an inner cavity, and a partition is disposed in the water tank body. Two ends of the partition abut against the inner wall of the water tank body respectively, so as to separate the inner cavity of the water tank body into a first cavity and a second cavity.
  • the first cavity communicates with a first pipe, and the second cavity communicates with a second pipe.
  • the water tank further comprises a first connecting hole and a second connecting hole, wherein the first connecting hole and the second connecting hole are each defined by the water tank body and correspond to the first cavity and the second cavity, respectively. Under external force, both ends of the partition move along the inner wall of the water tank body to adjust the capacities of the first cavity and the second cavity.
  • a cleaning robot 100 includes a flexible roller 10, a roller motor 11 for driving the flexible roller 10 to rotate, and a water sink 30.
  • a gap is defined between the flexible roller 10 and the water sink 30.
  • the cleaning robot 100 further comprises a first pipe 55 and a second pipe 56 respectively connected to the water sink 30 and the water tank 50.
  • the cleaning robot 100 further comprises a pressing member 35 for deforming the flexible roller 10 to press out sewage and a roller brush 20 on a long side of the flexible roller 10.
  • the bristles of the roller brush 20 are in contact with the flexible roller 10, and at least a portion of a garbage collection box 40 is located below the roller brush 20.
  • the flexible roller 10 is driven by the roller motor 11 to rotate to attach solid waste thereto, sweep the solid waste into the garbage collection box 40, and absorb liquid waste in the flexible roller 10. Clean water in the water sink 30 flows into the flexible roller 10 to provide the flexible roller 10 with clean water.
  • the flexible roller 10 When the flexible roller 10 cleans the ground, the flexible roller 10 absorbs the liquid waste on the ground and the sewage mixed therewith.
  • the flexible roller 10 which has absorbed the sewage, rotates against the pressing member 35, a contacted portion of the flexible roller 10 is compressed by the pressing member 35.
  • the resulting compression causes the sewage absorbed by the flexible roller 10 to be pressed upwards, causing the sewage to have an upward pressure and flow upward.
  • the flexible roller 10 generates an upward deformation on both sides of the compressed portion of the flexible roller 10, so that the side of the compressed portion of the flexible roller 10 that was originally round or nearly round fills the gap between the flexible roller 10 and the water sink 30.
  • the discharged sewage is upwardly driven due to the upward pressure and pressed into the water sink 30 upwards.
  • the upward pressure generated by the deformation is greater than the gravity of the sewage stored in the water sink 30 plus the sewage stored in the second pipe 56 (i.e., the sewage pipe), the sewage flows into the water sink 30,
  • the rotary shaft of the flexible roller 10 is made of a hard material, and the outer peripheral portion thereof is made of a flexible material, for example, made of a sponge, a cotton cloth, etc. Clean water is easily absorbed due to the porosity of the material and the surface cleaning power, and it is easy to clean the ground.
  • the flexible roller 10 is driven and rotated by the roller motor 11, and the roller motor 11 is also mounted inside the rotary shaft of the flexible roller.
  • the rotation speed of the flexible roller 10 will affect the cleaning ability of the cleaning robot 100, so it is necessary to reasonably set the rotation speed of the flexible roller 10 and to use different rotation speeds when cleaning different environments.
  • the rotational speed of the flexible roller 10 may be set at 50-140 revolutions per minute (rpm). In a preferred embodiment, the rotational speed of the flexible roller 10 may be set at 70 rpm. The smoother the ground (i.e., the lower the friction on the ground) the smaller the required rotation speed.
