Drive system for a surface treatment apparatus and a surface treatment apparatus having the same
A surface treatment apparatus may include a first agitator, a second agitator, and a drive system configured to cause the second agitator to rotate concurrently with the first agitator, the drive system including at least a first magnetic gear and a second magnetic gear.
1. A surface treatment apparatus comprising:
a first agitator;
a second agitator; and
a drive system configured to cause the second agitator to rotate concurrently with the first agitator, the drive system including:
at least a first magnetic gear and a second magnetic gear; and
a temporary magnet disposed between the first magnetic gear and the second magnetic gear.
2. The surface treatment apparatus of claim 1 further comprising an agitator motor configured to cause the first agitator to rotate.
3. The surface treatment apparatus of claim 1 , wherein the drive system is configured to cause the first and second agitator to rotate at different speeds.
4. The surface treatment apparatus of claim 1 , wherein the drive system is configured to cause the first and second agitator to rotate in a common direction.
5. The surface treatment apparatus of claim 1 , wherein the temporary magnet is an iron pin.
6. The surface treatment apparatus of claim 1 , wherein a diameter of the first agitator measures differently from a diameter of the second agitator.
7. The surface treatment apparatus of claim 1 , wherein the first magnetic gear is coupled to the first agitator and the second magnetic gear is coupled to the second agitator.
8. The surface treatment apparatus of claim 1 further comprising a body, the first agitator and the second agitator being rotatably coupled to the body and at least one of the first agitator or the second agitator is configured to move along at least one axis.
9. The surface treatment apparatus of claim 8 , wherein the first agitator is configured to move along the at least one axis independent of the second agitator.
10. A surface treatment apparatus comprising:
an upright section; and
a surface treatment head including:
a first agitator;
a second agitator; and
a drive system having:
a first magnetic gear coupled to the first agitator;
a second magnetic gear coupled to the second agitator, a rotation of the first magnetic gear causing a corresponding rotation of the second magnetic gear; and
a temporary magnet disposed between the first magnetic gear and the second magnetic gear.
11. The surface treatment apparatus of claim 10 further comprising an agitator motor configured to cause the first agitator to rotate.
12. The surface treatment apparatus of claim 10 , wherein the drive system is configured to cause the first and second agitator to rotate at different speeds.
13. The surface treatment apparatus of claim 10 , wherein the drive system is configured to cause the first and second agitator to rotate in a common direction.
14. The surface treatment apparatus of claim 10 , wherein the temporary magnet is an iron pin.
15. The surface treatment apparatus of claim 10 , wherein a diameter of the first agitator measures differently from a diameter of the second agitator.
16. The surface treatment apparatus of claim 10 , wherein the first agitator is cantilevered.
17. The surface treatment apparatus of claim 10 further comprising a body, the first agitator and the second agitator being rotatably coupled to the body and at least one of the first agitator or the second agitator is configured move along at least one axis.
18. The surface treatment apparatus of claim 17 , wherein the first agitator is configured to move along the at least one axis independent of the second agitator.
