  • Patent number: 10765191
    Abstract: A diffuser includes an air inlet for receiving an airflow from a hair dryer, a grille having a plurality of air outlets for emitting a first part of the airflow from the diffuser, and a plurality of projections upstanding from the grille for contacting the hair of a user and for emitting a second part of the airflow. Each of the projections has a respective air outlet located in an end portion of the projection which is remote from the grille. The projections are divided into a first set of projections and a second set of projections arranged about the first set of projections. The air outlets of the first set of projections are arranged to emit air towards the second set of projections, and the air outlets of the second set of projections face are arranged to emit air towards the first set of projections.

  • Patent number: 10213001
    Abstract: 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.
