Patent number: 10213001Abstract: An attachment for a hand held appliance, the attachment including an outer wall with a first part which is generally conical in shape, and a fluid inlet into the outer wall, wherein the fluid inlet is formed from a discontinuity in the outer wall. The outer wall may be formed from a first wall and a sleeve. The first wall may define a fluid flow path through the attachment. The sleeve may extend around the first wall forming a second fluid flow path from the fluid inlet in the outer wall, the second fluid flow path extending between the first wall and the sleeve. An outer surface of the sleeve and an outer surface of the first wall may be collinear. The fluid flow path may extend from a first fluid inlet into the attachment to a first fluid outlet. The first fluid inlet may be annular.Type: GrantFiled: January 21, 2016Date of Patent: February 26, 2019Assignee: Dyson Technology LimitedInventors: Philip Jonathan Stephens, Stephen Farrar Smith, William Keith Hassett, Antoine Francois Atkinson
