Description

Cleaning head rolling brush with adjustable length

Technical Field

The invention relates to a cleaning device, in particular to a rolling brush applied to a cleaning head.

Background

Brush bars are used in vacuum cleaners as part of the cleaner head to agitate dirt and dust on the surface to be cleaned. The agitation helps the dust to rise from the surface so that it can then be sucked up into the separator. At present, the length of a brush rod of a cleaning head is fixed, so that the radiating area of the cleaning head corresponding to the brush rod is limited, the cleaning head can only operate in a large space, and the cleaning head is difficult to go deep into narrow and small spaces, so that incomplete cleaning is caused. Although there are foldable suction heads, the height of the suction head is sacrificed to meet the requirement of the length of the suction head, so that the cleaning and the disposal of a small space are inconvenient.
