Floor brush and dust collector

Abstract

The invention provides a floor brush and a dust collector. The floor brush comprises a shell, a rolling brush, a normally-closed switch, a pusher mechanism and a reset structure; the shell comprises abase and a cover body, the cover body capable of being opened and closed is arranged on the base, and the cover body can move to the opening position from the closed position under the action of external force of the inner side of the cover body; the rolling brush can be rotatably arranged in the shell; the normally closed switch is in closed connection with a rolling brush motor circuit drivingthe rolling brush to rotate; the pusher mechanism is arranged in the shell, when the pusher mechanism is in the initial position, the normally closed switch is in a closed state, and the pusher mechanism is driven by the cover body moving to the opening position from the closed position to move to the toggle position from the initial position to push the normally closed switch to be disconnected;the reset structure can drive the pusher mechanism to move to the initial position from the toggle position under the action of external force, and correspondingly, the normally closed switch returnsto the switch closed state from the switch off state. The floor brush is safe and reliable when clearing away winding objects on the rolling brush.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment, in particular to a floor brush and a vacuum cleaner. Background technique [0002] During the use of the vacuum cleaner, the roller brush is driven by the motor through the belt to sweep the dust and debris on the surface to be cleaned to a position where it can be sucked. Since the roller brush protrudes downward and is exposed, it will cause hair, etc. The thread is wound along the outer wall of the roller brush. However, the protection against winding and shutting down of soft objects such as vacuum cleaner suction lines and curtains is generally completed by the blocking protection of the roller brush motor, which leads to a certain degree of winding and blocking of soft objects on the floor brush, which not only increases the workload of cleaning , and the extrusion force of the winding on the roller brush assembly may also cause damage to the ground brush parts. [0003] The pr...
