Vacuum cleaner floor brushes and vacuum cleaners

Abstract

A ground brush for a vacuum cleaner, comprising a housing, a motor mounted on the housing, and a rolling brush assembly supported on the housing, the rolling brush assembly including a rolling brush shaft driven by the motor and connected to the rolling brush The rolling brush body connected with the brush shaft is characterized in that the rolling brush shaft is provided with first end teeth, the rolling brush body is provided with second end teeth, and the first end teeth and the second end teeth The teeth cooperate so that the brush shaft transmits torque to the brush body, and when the torque of the brush shaft is greater than a preset threshold, the teeth at the first end and the teeth at the second end move relatively axially The disengagement is used to interrupt the torque transmission of the rolling brush axially to the rolling brush body; the present invention also provides a vacuum cleaner using the ground brush of the vacuum cleaner.

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...
