Patent number: 11849904Abstract: A cleaner head for a vacuum cleaner has a housing, an agitator mounted within the housing, and a drive mechanism for driving the agitator about a first axis A. The drive mechanism is mounted to the housing for rotation about a second axis R. The second axis R is offset from the first axis A. When the agitator is brought into contact with a surface to be cleaned, the surface exerts a reaction torque on the agitator that causes the drive mechanism to rotate about the second axis R.Type: GrantFiled: February 26, 2019Date of Patent: December 26, 2023Assignee: Dyson Technology LimitedInventors: Richard Iain Mockridge, Anthony Andrew Buchanan Harker, William James Baker

Patent number: 11368071Abstract: An electric drive includes a motor and a transmission for transferring torque from the motor to a tool. The transmission includes a plurality of planetary rollers which are driven by a rotary shaft of the motor, and an output ring which is connectable to the tool, and which is driven by the planetary rollers. The transmission further includes a roller casing which is secured to a housing of the motor, and which supports parallel planetary shafts upon which the planetary rollers are mounted for rotation relative to the roller casing, and a bearing having an inner race which engages the roller casing, and an outer race which engages the inner periphery of the output ring.Type: GrantFiled: February 18, 2019Date of Patent: June 21, 2022Assignee: Dyson Technology LimitedInventors: David Colin Worker, Richard Iain Mockridge
