A vacuum cleaner nozzle having a nozzle body and a brush roll configured to rotate relative to the nozzle body. The nozzle comprises a locking assembly having a locked state, in which the locking assembly locks the brush roll to the nozzle body, and an unlocked state, in which the locking assembly unlocks the brush roll from the nozzle body. The nozzle comprises a button, wherein the locking assembly is configured to, when in the locked state, assume the unlocked state after a displacement of the button in a first direction, and when in the unlocked state, assume the locked state after a displacement of the button in the first direction. The present disclosure further relates to a vacuum cleaner comprising a nozzle.

Disclosed is an electric cleaning brush, including a handle and a brush broom assembly, where the brush broom assembly includes a frame, a motor and a rolling brush, the rolling brush includes a roller, the handle is connected to the frame provided with the motor, a fixed shaft is arranged on the frame, the motor has an output rotating shaft, and the output rotating shaft and the fixed shaft are arranged on a common central axis; and a first coupling groove and a second coupling groove are separately formed on two ends of the roller, a connecting hole is formed between the first coupling groove and the second coupling groove, the motor and the fixed shaft are disposed inside the first coupling groove and the second coupling groove respectively, the output rotating shaft is inserted into the connecting hole, and the output rotating shaft and the roller rotate synchronously.
