Abstract

A cleaning structure for autonomous moving floor sweeping machines includes a floor sweeping roller driven by a second servomotor to spin and clear dirt on the floor, a dust guide plate located at one side of the floor sweeping roller and interposed between a driving wheel and the floor sweeping roller, a flexible barrier plate located below the dust guide plate in contact with the floor to prevent the dirt from passing through under the dust guide plate towards the driving wheel, a dust guarding hood located at another side of the floor sweeping roller and a fender jutting and extended below the dust guarding hood to prevent residual dirt from forming falling dust dropping to the floor. The floor sweeping roller also can spin at high speeds to sweep the floor quickly and efficiently.

Claims

1. A cleaning structure for an autonomous moving floor sweeping machine which includes at least a cleaning structure, a battery to support operation of the floor sweeping machine, a driving wheel to drive movement of the floor sweeping machine, a first servomotor to drive the driving wheel, a second servomotor to drive the cleaning structure to perform cleaning tasks, a microcontroller unit to control spinning of the first and second servomotors, a light emission member activated by a voltage sent and converted by the microcontroller unit, a light receiving member to receive light from the light emission member and convert the light to send to operate the microcontroller unit and a function key to select preset functions provided by the microcontroller unit to control the first and second servomotors, the cleaning structure comprising:

a floor sweeping roller driven by the second servomotor to spin and clear dirt on a floor;

a dust guide plate located at one side of the floor sweeping roller and interposed between the driving wheel and the floor sweeping roller;

a flexible barrier plate located below the dust guide plate in contact with the floor to prevent the dirt from passing through under the dust guide plate towards the driving wheel;

a dust guarding hood located at another side of the floor sweeping roller; and

a fender jutting and extended below the dust guarding hood to prevent residual dirt from forming falling dust dropping to the floor.

2. The cleaning structure for an autonomous moving floor sweeping machine of claim 1 further including a dust collection chamber formed by partitioning of the dust guide plate, the dust collection chamber including a passage communicating with the floor sweeping roller.

3. The cleaning structure for an autonomous moving floor sweeping machine of claim 1 further including a floor sweeping side roller located at a distal end of the floor sweeping roller and driven to spin synchronously with the floor sweeping roller.

4. The cleaning structure for an autonomous moving floor sweeping machine of claim 2 further including a floor sweeping side roller located at a distal end of the floor sweeping roller and driven to spin synchronously with the floor sweeping roller.

5. The cleaning structure for an autonomous moving floor sweeping machine of claim 1, wherein the barrier plate is detachably coupled on a lower side of the dust guide plate.

6. The cleaning structure for an autonomous moving floor sweeping machine of claim 2, wherein the barrier plate is detachably coupled on a lower side of the dust guide plate.

7. The cleaning structure for an autonomous moving floor sweeping machine of claim 3, wherein the barrier plate is detachably coupled on a lower side of the dust guide plate.

8. The cleaning structure for an autonomous moving floor sweeping machine of claim 4, wherein the barrier plate is detachably coupled on a lower side of the dust guide plate.

9. The cleaning structure for an autonomous moving floor sweeping machine of claim 1, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

10. The cleaning structure for an autonomous moving floor sweeping machine of claim 2, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

11. The cleaning structure for an autonomous moving floor sweeping machine of claim 3, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

12. The cleaning structure for an autonomous moving floor sweeping machine of claim 4, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

13. The cleaning structure for an autonomous moving floor sweeping machine of claim 5, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

14. The cleaning structure for an autonomous moving floor sweeping machine of claim 6, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

15. The cleaning structure for an autonomous moving floor sweeping machine of claim 7, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.

16. The cleaning structure for an autonomous moving floor sweeping machine of claim 8, wherein the second servomotor spins at a speed ranged from 2700 rpm to 4100 rpm.
