Abstract
A suction brush assembly for a vacuum cleaner capable of automatic height adjustment according to the present disclosure includes a suction brush body connected to a cleaner body at a rear side thereof and provided with a rotation brush for striking a surface to be cleaned to separate dirt from the surface to be cleaned at a bottom surface thereof; and an up/down adjusting unit for monitoring continuously a state of the surface to be cleaned and adjusting a height of the rotation brush body to vary a distance between the surface to be cleaned and the rotation brush according to the state of the surface to be cleaned so as to prevent the surface to be cleaned from being damaged by the rotating rotation brush.
Claims11
A suction brush assembly, comprising:
- a suction brush body connected to a cleaner body at a rear side thereof and provided with a rotation brush for striking a surface to be cleaned to separate dirt from the surface to be cleaned at a bottom surface thereof;
- and
- an up/down adjusting unit for monitoring continuously a state of the surface to be cleaned and adjusting a height of the rotation brush body to vary a distance between the surface to be cleaned and the rotation brush according to the state of the surface to be cleaned so as to prevent the surface to be cleaned from being damaged by the rotating rotation brush.
A suction brush assembly, comprising:
- a suction brush body for drawing-in dirt on a surface to be cleaned to introduce the drawn-in dirt to a cleaner body;
- a rotation brush disposed at a front of the suction brush body and driven to rotate by a first motor so as to promote a separation of the dirt from the surface to be cleaned;
- a pair of main wheels rotatably coupled to both sides of the rear side of the suction brush body respectively;
- a current detecting sensor for detecting a variation in current generated in the first motor by a friction resistance generated between the rotation brush and the surface to be cleaned;
- an up/down driving part disposed in an inside of the suction brush body, for moving up/down a front side of the suction brush so as to maintain a contacting distance between the rotation brush and the surface to be cleaned;
- and
- a control part for comparing a current variation signal detected by the current detecting sensor with a preset current range and driving the up/down driving part according to the compared value.
A suction brush assembly, comprising:
- a brush;
- a first motor operatively connected to the brush so that the motor rotates the brush;
- a current sensor electrically connected to the first motor, the current sensor detecting a current variation signal from the first motor;
- a control part electrically connected to the current sensor so that the control part receives the current variation signal from the current sensor;
- and
- a second motor electrically connected to the control part, the second motor being configured to raise or lower the brush with respect to a surface being cleaned based at least in part on the current variation signal.
