Problems solved by technology

Because the roller brush is in direct contact with sundries, soft objects such as hair, curtains, and threads from the outside are easy to wrap around the outer wall of the roller brush, causing the roller brush to stall and causing damage to the motor, roller brush body and other components

Abstract

The invention discloses a vacuum cleaner ground brush, which comprises a shell, a motor mounted on the shell, and a rolling brush assembly supported on the shell. The rolling brush assembly comprises a rolling brush shaft driven by the motor, and a rolling brush body connected with the rolling brush shaft. The vacuum cleaner ground brush is characterized in that first end teeth are arranged on the rolling brush shaft, and second end teeth are arranged on the rolling brush body; the first end teeth and the second end teeth are matched, so that the rolling brush shaft transmits torque to the rolling brush body; and when torsion of the rolling brush shaft is larger than a preset threshold value, the first end teeth and the second end teeth oppositely and axially move to be unmatched so as to interrupt torque transmission from the rolling brush shaft to the rolling brush body. The invention further provides a vacuum cleaner using the vacuum cleaner ground brush.

Description

technical field [0001] The invention relates to an electrical appliance for cleaning, in particular to a brush for a vacuum cleaner and the vacuum cleaner. Background technique [0002] At present, during the use of the vacuum cleaner, the motor drives the roller brush to rotate through the transmission mechanism to suck dust and sundries. Because the roller brush is in direct contact with sundries, soft objects such as hair, curtains, and threads from the outside are easy to wrap around the outer wall of the roller brush, causing the roller brush to stall, causing damage to the motor, roller brush body and other components. Contents of the invention [0003] The invention provides a floor brush for a vacuum cleaner and a vacuum cleaner using the floor brush of the vacuum cleaner. When the rolling brush is blocked, the torque transmission between the rolling brush body and the rolling brush shaft can be automatically interrupted to protect the rolling brush assembly, the m...
