Washing devices comprise an integrally formed brush component including a hub having a central axis and a plurality of bristles. Each bristle includes a shaft extending from the hub and having outwardly extending cleaning structures. The bristles extend radially from the central axis of the hub. A cylindrical support comprises a webbing having an array of holes positioned to receive the bristles of the brush component, each of the bristles being received within and extending outwardly from respective holes in the webbing. Alternate embodiments comprise an integrally-formed, linear brush component including a plurality of connected hub elements, each hub element carrying a bristle. Each bristle includes an elongated shaft having multiple cleaning structures extending outwardly. A webbing comprises an array of holes positioned to receive the bristles of the linear brush component, each of the bristles being received within and extending outwardly from respective holes in the webbing.

Provided is a brush head for an oral cleaning device for cleaning teeth with a combination of brushing and emitting of a cleaning agent. The brush head comprises a bristle set for brushing the teeth and a nozzle for emitting the cleaning agent. When actuating the bristle set from a first configuration, which is optimized for brushing, to a second configuration, which is optimized for emitting of a cleaning agent, at least a part of the bristle 5 set is moved away from the nozzle and/or away from a path of the cleaning agent when being emitted from an orifice of the nozzle.

The applicator for applying a haircare product comprises a base 12 and spikes 14 protruding with respect to the base. At least a plurality of spikes 14 each have a cross section of elongate shape in at least one direction of extension. At least some of the spikes of said plurality of spikes are made at least partially of porous material that is able to absorb said haircare product.

Automatic toothbrushes are disclosed herein. A toothbrush configured in accordance with embodiments of the present technology can include, for example, a handle and a mouthguard coupled to the handle. The mouthguard can be configured to be positioned within a mouth of a user over multiple teeth of the user. A brush assembly having a plurality of bristles can be removably positioned within the mouthguard for engaging and cleaning the teeth of the user. A motor can be disposed within or coupled to the handle and configured to articulate the brush assembly within the mouthguard.

Disclosed is a cleaning unit comprising a variable brush portion. The cleaning unit according to an embodiment of the present invention comprises a shaft capable of reciprocating along an axial direction, wherein a first cam protrudes from the outer circumferential surface of the shaft. In addition, the brush portion is arranged on the outer circumferential surface of a body member surrounding the shaft, and the brush portion includes a second cam engaged with the first cam. When the shaft is moved in the axial direction, the first cam pushes the second cam in a radial direction, whereby the brush portion may protrude in the radial direction. That is, as the shaft reciprocates in the axial direction, the length of the brush portion protruding from the outer circumferential surface of the body member may vary.

A paintbrush with adjustable bristle width, length, angle and/or shape that allows the user to configure the shape of the application surface as desired, thus eliminating the need for painters to utilize multiple traditional paintbrushes with different bristle configurations for different size and shaped surfaces being painted. The invention includes multiple bristle pack segments, elongated guideways, finger adjustment knobs, finger knob slide slots, and a brush slide body housing wherein the mechanisms for adjusting the length of the individual bristle pack segments are contained; is scalable, wherein different overall sizes and widths of paintbrushes can be manufactured which retain the unique adjustability of the invention; can be manufactured with or without a handle, allowing the invention to utilize a wide variety of handles of various materials, sizes and shapes which can be affixed to the bristle slide body housing; is not limited to a specific number of bristle pack segments, elongated guideways and finger knob slide slots; is not limited to specific sized bristle pack segments, elongated guideways and finger knob slide slots; is suitable for manufacturing using various materials; is siutabe for manufacturing utilizing various bristle materials (e.g., Black China, White China, Ox Hair, synthetic materials, etc.); may be modified for use with a self-feeding paint mechanism; is not limited to the purpose of applying paint; is suitable for applying coatings including paint; may be manufactured in various colors; may be manufactured using various graphics.

A cosmetic brush having a flare-shaped ferrule at its mouth, through which an advanceable and retractable, resilient bristle brush extends. The brush connects in the handle, with an elevator mechanism that has a cupped upper end which carries the brush, and effects the axial movement thereof. As more bristles are exposed at the ferrule's flare-shaped mouth in response to their advancing movement, the degree of flare of the brush increases. The resilience of the exposed bristles along with the flare adjustability, creates the same effect as a plurality of different sized, smaller brushes. There is thus eliminated the need for carrying multiple different sized brushes that might otherwise be required in order to produce an equivalent optimal brushing result.
