The utility model provides an in the embodiment, provide a robot of sweeping floor, should sweep floor the robot and include dust collecting system, traveling system and power supply system, dust collecting system is used for collecting subaerial dust, and traveling system is used for driving the robot of sweeping floor and removes, and power supply system is used for providing the energy of work for dust collecting system and traveling system.

The dust collection system comprises a rolling brush mechanism, a dust collection box, an air duct and a fan, wherein the dust collection box is connected with an outlet of the rolling brush mechanism, and the air duct is connected between the dust collection box and the fan; the rolling brush mechanism during operation takes the subaerial dust up, then through the suction that the fan produced, will be mixed with the air suction of dust inside the robot of sweeping the floor, the air current that is mixed with the dust is filtered in the dust collecting box when the dust collecting box, and clean air is discharged after the fan from the wind channel, so realizes the dust absorption function.

Referring to fig. 1, the rolling brush mechanism 200 includes a housing (not shown), a rolling brush assembly 100, and a rolling brush cover 210, wherein the rolling brush cover 210 is coupled to the housing and encloses to form a rolling brush cavity, and the rolling brush assembly 100 is disposed in the rolling brush cavity to assemble and protect the rolling brush assembly 100 through the rolling brush cavity. Specifically, the housing has an opening through which the roll brush assembly 100 is disposed in the housing, and the roll brush cover 210 covers the opening and is coupled to the housing. Thus, a roll brush chamber is defined between the housing and the roll brush cover 210 to assemble the roll brush assembly 100 in the roll brush chamber. Moreover, the rolling brush cover 210 is provided with a dust suction port 211 communicated with the rolling brush cavity, the rolling brush assembly 100 can contact with the ground through the dust suction port 211 to take dust and other garbage on the ground, and then the garbage is sucked into the sweeping robot through negative pressure to finish dust suction.

Referring to fig. 2-3, the rolling brush assembly 100 includes a roller 10 and a brush 30, the roller 10 is connected to a motor, the brush 30 is disposed on the surface of the roller 10, the motor drives the roller 10 to rotate around its axis when the motor works, and further drives the brush 30 on the surface of the roller 10 to rotate, and the rotating brush 30 contacts with the ground to drive garbage such as dust on the ground to clean. Specifically, the brush body 30 includes a glue brush 50 and a brush 70, the brush 70 has a windward side 71 and a leeward side 73 opposite to each other along the rotation direction a of the roller body 10, and the glue brush 50 is located on the windward side 71 and abuts against the brush 70. The windward side 71 is located in front of the brush 70 in the rotation direction a, and the leeward side 73 is located behind the brush 70 in the rotation direction a. In other words, the brush 70 is disposed in the rotation direction a of the roller 10, and then the glue brush 50 is disposed in front of the brush 70, and the glue brush 50 is abutted against the windward side 71 of the brush. In the rotating process of the roller body 10, the rubber brush 50 which is kept in front of the brush 70 contacts with the ground first to keep off the hair on the ground, so that the hair is prevented from being wound on the brush 70, thereby reducing the hair winding, preventing the rolling brush assembly 100 from being stuck due to the hair winding, and improving the working efficiency of the rolling brush assembly 100.

Further, the distance from the side of the brush 70 away from the roller body 10 to the roller body 10 is greater than the distance from the side of the glue brush 50 away from the roller body 10 to the roller body 10. Equivalently, the brush 70 is partially protruded out of the rubber brush 50, and the brush 70 is at least partially protruded out of the rubber brush to contact with the ground for cleaning work through the protruded part of the brush 70 relative to the rubber brush 50 while blocking hairs from being entangled with the brush 70.

It can be understood that, the protruding portion of the brush 70 relative to the rubber brush 50 is in interference fit with the ground, in the rotating process of the rolling brush assembly 100, the rubber brush 50 firstly cleans up the garbage such as the hair on the ground, then the brush 70 located behind the rubber brush 50 contacts with the ground, when the brush 70 contacts with the ground, because the brush 70 is in interference fit with the ground, the brush 70 can be bent towards the direction opposite to the rotating direction a under the effect of the ground, that is, the brush 70 is bent towards the direction away from the rubber brush 50, the bent brush 70 can be located behind the rubber brush 50 completely, and the rubber brush 50 can still prevent the hair from winding on the brush 70. Therefore, although the brush 70 is partially protruded out of the glue brush 50 to conveniently clean up the dust and other garbage on the ground through the brush 70, the brush 70 is bent in the direction away from the glue brush 50 during the cleaning process, the protruded tip part of the brush 70 relative to the glue brush 50 can still be bent behind the glue brush 50, and the top end of the brush 70 can still be protected by the glue brush 50 to prevent the hair from being entangled with the top end of the brush 70.

Referring to fig. 3-6, in some embodiments, the brush 70 is detachably disposed relative to the roller 10, so that the brush 30 has two states, in one state, the brush 30 includes the brush 70 and the rubber brush 50, the brush 30 can not only use the rubber brush 50 to clean large-particle garbage, such as soybeans, etc., but also use the brush 70 to clean small-particle garbage, such as dust, etc., so that the floor can be completely cleaned through the cooperation of the rubber brush 50 and the brush 70, and the cleaning effect is better. The brush 70 is dismantled under another state, and the brush body 30 only includes gluey brush 50, can use when clearing up large granule rubbish, can dismantle brush 70 this moment, through gluey brush 50 clearance rubbish can, simultaneously brush 70 can not be contaminated, improves brush 70's utilization ratio. Thus, the brush body 30 has a plurality of states. In addition, the brush 70 is detachably arranged relative to the rubber brush, so that the brush 70 is convenient to clean.
