A head for a personal care device having a carrier including a front surface, at least one cleaning element partly embedded in the carrier and thus having an embedded cleaning element portion and a non-embedded cleaning element portion extending from the front surface of the carrier between a base end on the front surface and a free end; the embedded cleaning element portion extending from the front surface between a top end on the front surface and a bottom end, wherein the base end of the non-embedded cleaning element portion has a base end cross-sectional shape and a base end cross-sectional area, and the top end of the embedded cleaning element portion has a top end cross-sectional shape that is different to the base end cross-sectional shape and a top end cross-sectional area that is larger than the base end cross-sectional area.

An electric toothbrush head and an electric toothbrush are provided. The electric toothbrush head includes a brush head body, bristles and a flexible member. The brush head body includes a brush rod and a brush plate. The brush plate is elastically deformable and has a non-deformed state and an elastically deformed state relative to the brush rod. An included angle between the brush plate and the brush rod is changeable within a range from 0 degrees to X degrees. The X degrees are equal to or greater than 10 degrees. The elastically deformed state includes a first deformed state in which the brush plate is bendable or deformable towards a front surface relative to the brush rod and a second deformed state in which the brush plate is bendable or deformable towards a back surface relative to the brush rod.

An apparatus for removing scratches from tooth enamel configured like a toothbrush that has buffing material where the toothbrush has bristles. Configured in several different iterations so as to comprise a toothbrush shaped instrument that provides ways to attach buffing material. One iteration places the buffing material over the head. Another iteration includes a pad between the head and the buffing material in three buffing surfaces each one of flat, concave, and convex. The pad and buffing material configured severally to facilitate mating to the neck of the apparatus by known methods. The head further including an integrated head portion, pad, and buffing material in one of flat, concave, and convex shapes that attach to the neck and handle. The user places the buffing material against the teeth and moves the apparatus back and forth to buff the surfaces and smooth the enamel.

A cleaning system for a solar panel is provided. The cleaning system comprises: i) a frame moveable in a transverse direction over the solar panel, the frame having edges oriented in the transverse direction; a brush assembly positioned within the frame and moveable in a longitudinal direction including a plurality brush holders arranged within the frame, with each brush holder being adapted to interchangeably receive a brush for cleaning the solar panel; and a liquid spray arrangement including nozzles arranged one or more rows for spraying at least one of water and a water detergent mix onto the solar panel. The liquid spray arrangement includes nozzles positioned near at least one of the transverse edges of the frame for spraying the water detergent mix onto a longitudinal end of the brush assembly.

A toothbrush with a system to replace the bristle head. The present invention patent application follows, for a toothbrush, aimed at oral hygiene, which through a male coupling formed by a tongue with claw, both incorporated in the bristle head, which will couple in the female cavity of the handle, so that with the bristle lifetime end due to its wear, the head can be removed and replaced, providing economy, as well as less environmental impact.

A reconfigurable modular brush has a brush head including brush-head upper and lower surfaces extending longitudinally along a brush-head axis between brush-head first and second ends. Laterally opposed brush-head first and second sides extend between the brush-head upper and lower surfaces and longitudinally between the brush-head first and second ends. A bristle array is defined by a plurality of bristles protruding from the brush-head lower surface. A brush handle includes a grip portion and a brush-head mount, the brush handle having a lengthwise extent disposed generally along a handle axis between handle proximate and distal ends. The brush head and brush-head mount are cooperatively configured such that the handle can selectively capture and retain the brush head. Moreover, the longitudinal orientation in which the brush head is captured and retained by the brush handle is selectively reversible.

A toilet brush assembly including a brush, including: a handle assembly including a handle assembly proximal end and a handle assembly distal end; and a brush head that includes a plurality of tufts of bristles disposed on an outer surface of the brush head, a cavity defined by an inner surface of the brush head, and a fastener portion. The toilet brush assembly also includes a base, including a cup for receiving the brush head. The brush head selectively couples to the handle assembly distal end at the fastener portion of the brush head at a handle assembly-brush head connection; and at least one of the base and the brush head define at least one interference feature formed from a surface of the base and that contacts the tufts of bristles when the brush head is in a rest position within the cup.

An oral care implement including a handle and an oral care refill head. The handle has a gripping portion, an engagement component coupled to a distal end of the gripping portion, and a stem. The engagement component includes a plate portion and a first engagement feature. The stem extends through an opening in the engagement component and protrudes from the plate portion. The oral care refill head includes an oral care treatment portion and a sleeve portion. The sleeve portion has an inner surface that defines a sleeve cavity having a cavity axis and a second engagement feature. When the oral care refill head is detachably coupled to the handle, the first and second engagement features mate with one another to at least one of: (1) position the oral care refill head and the handle in an operational alignment; and (2) lock the oral care refill head to the handle.
