Dust collector, floor brush device and rolling brush

Technical Field

The utility model relates to a dust absorption technical field especially relates to dust catcher, scrubbing brush device and round brush.

Background

Along with the improvement of people's standard of living, it is more and more higher to the clean environment on every side, especially in the family is clean, needs carry out thorough cleanness to the inside dirt of house, but can not satisfy indoor cleanliness through traditional mode, and waste time and energy moreover, and the dirt and the filth in the clean room that the dust catcher can be effective and quick satisfy people's requirement. Therefore, it is widely used.

Generally, a vacuum cleaner can collect and clean dregs, particles, etc. well by a strong suction force. However, in the cleaning process, the entanglement such as hair and thread ends is easily wound on the rolling brush of the dust collector, and along with the high-speed rotation of the rolling brush, the entanglement can move from the current position to the two axial ends of the rolling brush to form friction force, so that the rotation of the rolling brush is influenced, and the rolling brush cannot be normally used.

SUMMERY OF THE UTILITY MODEL

Based on this, it is necessary to provide a roll brush which prevents the entanglement from affecting the rotation of the roll brush itself.
