Example:

As shown in Figure 1, the present invention provides a sweeping device for a cleaning robot, which includes a fuselage 1, active front wheels 2 are installed on both sides of the front of the fuselage 1, and active front wheels 2 are respectively installed on both sides of the rear of the fuselage 1. A driven rear wheel 3 is installed, and the two driving front wheels 2 are connected by a rotating shaft 4, and a rolling brush 5 is sleeved outside the rotating shaft 4, and the bristles 6 of the rolling brush 5 are all clockwise Placed in rotation and the bottom of the bristles 6 is just close to the ground, the inner side of the driven rear wheel 3 is provided with a first gear 7, and the first gear 7 and the driven rear wheel 3 are fixedly connected by a fixed rod 8, And the first gear 7 is connected with the second gear 9 through meshing, and the second gear 9 is located between the driven rear wheel 3 and the driving front wheel 2 and placed horizontally, and the center of the bottom surface of the second gear 9 is connected with A brush bar 10, the bottom end of the brush bar 10 is connected with a brush 11, the bristles 6 of the brush 11 are all inclined downward and the bottom of the bristles 6 is just close to the ground, the upper half of the fuselage 1 A dust collection box 12 is provided, and the bottom of the dust collection box 12 is provided with a first dust suction port 13 and a second dust suction port 14, the first dust suction port 13 is located directly above the roller brush 5, and the first dust suction port 13 is located directly above the roller brush 5. Two suction ports 14 are located on the bottom surface of the fuselage 1 behind the driven rear wheel 3 .

When the present invention is in use, the power supply provides energy for the active front wheel 2, and the active front wheel 2 rotates to make the cleaning robot move forward. 5. It can roll up the large pieces on the ground and the garbage close to the ground, and be sucked into the dust box 12 by the first dust suction port 13. When the robot advances, it will also drive the driven rear wheel 3 to rotate. When the first gear 7 rotates, the second gear 9 meshed with the gears will also rotate, and the brush 11 on the second gear 9 will rotate, so that the remaining fine dust and garbage on the ground will gather at the bottom of the fuselage 1 and be vacuumed by the second gear. Port 14 sucks dust box 12, completes the overall cleaning of robot to ground.

It is worth mentioning that the principle of dust suction at the first suction port and the second suction port is that the fan impeller is driven by the motor at high speed, and the air in the impeller is discharged from the fan at high speed, and at the same time, the air in the dust suction port is continuously replenished. The dust and dirt at the suction port of the fan are sucked into the dust box along with the air.

As shown in Figure 1, the first dust suction port 13 is parallel to the roller brush 5 and the length of the first dust suction port 13 is equal to the length of the roller brush 5, so that the dust brought by the rotation of the roller brush 5 can be completely absorbed by the first dust collector. The dust suction port 13 absorbs; the second dust suction port 14 is parallel to the first dust suction port 13 and the length of the second dust suction port 14 is equal to the length of the center line of the two hair brushes 11, so that the hair brush 11 rotates toward The dust gathered at the bottom of the fuselage 1 can all be absorbed by the second suction port 14; the edges and corners of the fuselage 1 are arc-shaped and the surface is smooth, so that the cleaning robot will not damage the furniture when it moves; The moving rear wheels 3 are all equal in size, so that the movement of the cleaning robot is more stable; the top of the dust collection box 12 is provided with a box cover 15, which is convenient for cleaning the dust and garbage in the dust collection box 12; the upper surface of the body 1 is smooth And there is no raised part, so that the cleaning robot can not touch these furniture when cleaning the bottom of the bed, the bottom of the sofa and the bottom of the cabinet; Cleans wooden and tiled floors without slipping.

The main features of the present invention are that (1) the present invention adds a rolling brush to the front half of the fuselage, and the rolling brush can roll up large pieces of garbage on the ground and rubbish close to the ground, and be sucked by the first dust suction port for dust collection The second half of the fuselage continues to use the brush, which can absorb the remaining fine dust and garbage, making the cleaning robot clean the ground more comprehensively. (2) The rolling brush of the present invention is driven by the rotation of the active front wheel, and the hair brush is driven by the rotation of the driven rear wheel and the meshing of the gears, so that the power supply only needs to provide electric energy to the active front wheel, which reduces power consumption and is worth popularizing .
