A brush head assembly comprising: a hard platen; a plurality of bristle tufts, each of which comprises a plurality of bristle strands, each bristle tuft having a proximal end and a free end; and a flexible matrix at least partially comprised of a shear-thickening material for coupling the plurality of bristle tufts to the hard platen, wherein the flexible matrix is arranged such that there is shear-thickening material between the proximal ends of the plurality of bristle tufts and the hard platen. A method of manufacturing the brush head assembly for use with a personal care appliance.

Washing devices, systems and methods comprise a brushing apparatus including vertical, elongated stanchions supporting a flexible, wave-like brush carrier. An array of brushes is mounted to the front of the brush carrier. In particular embodiments the brushes include hubs which are received within apertures formed by the brush carrier. The systems may include a single, relatively-wide stanchion, or multiple stanchions. The stanchions are articulated in an up-and-down, optionally orbital, movement. Spray nozzles and lights may be included in the stanchions and/or brush carrier.

An improvement of hair brush structure includes a brush head, a handle, and an adjustment device interconnected to the brush head and the handle. A repeated rotation of the adjustment device causes changing an appearance of the hair brush.

A brush useful for washing external surfaces, such as of a vehicle. The brush comprises a plurality of bristles connected to a hub. Each bristle has an elongated shaft having a number of cleaning structures extending outwardly from the shaft, providing multiple faces and edges arranged in a circumferential manner around the shaft, and producing multiple washing actions by the bristles as they are moved adjacent the surface. The hub and bristles may be integrally molded in a first condition having a planar form, and then folded relative to the hub to position the bristles extending from the hub in a cleaning direction from the hub. The hubs are secured to mounting structures by reception of the hubs in apertures in the mounting structures. In an embodiment, the mounting surfaces comprise flexible stanchions which are moved relative to an external surface to provide high resolution washing of a vehicle surface.

A surgical tool, systems, and method for cleaning an anatomical space is provided. At least one brush is disposed on a shaft extending through a tube. The tube includes a corresponding brush slot for each brush. A motor is operable to rotate the shaft to cause the at least one brush to move from a closed position to a cleaning position. The at least one brush is positioned entirely inside of the tube when in the closed position and at least partially outside of the tube when in the cleaning position. A fluid source is operable to supply fluid to the at least one brush as the at least one brush passes through the brush slot.

An interdental brush realizing reuse of parts by a simple structure includes a shaft portion including an internal passage which extends in an axial direction and of which distal end and base end are opened; and a brush on which fibers are implanted over an entire area of a core that is longer than extension length of the internal passage. The shaft portion further includes a grip portion of which a state is changed between a gripping state for gripping the brush, which has been inserted into the internal passage from an opening on a base end side and of which a part protrudes from an opening on a distal end side, to restrict the brush from moving in the axial direction, and a releasing state for releasing gripping of the brush to allow the brush to move in the axial direction.
