A brush for a vehicle washing system comprising: flexible elements (2) intended to come into contact with the vehicle for cleaning and/or polishing and/or drying; a central annular support (3) from which the flexible elements (2) extend; a shaft (4) rotating about its own axis (40) of rotation, the shaft (4) crossing the central support (3) and placing the central support (3) in rotation about the axis (40) of rotation;
the central support (3) comprising a lateral surface (35), from which the flexible elements (2) extend, which is inclined with respect to the axis (40) of rotation of the shaft (4).

A toothbrush includes a handle and a head connected to an end of the handle. The head has a surface. A plurality of bristles are mounted on the head so the bristles extend from the surface on only one side of the head. The plurality of bristles are arranged in a plurality of sets including first, second, and third sets. The bristles of each of the first, second, and third sets are substantially parallel to other bristles in the same respective set. The bristles in the first and third sets are oriented to angle outwardly from the bristles in the second set as they extend away from the surface.

A transport roller brush assembly that includes a base that is constructed to support a plurality of brush wires such that the plurality of brush wires are oriented to extend in a radial direction relative to an axis of rotation of an underlying material transport roller. The base is preferably split into at least two arcuate portions that can be removeably secured to one another preferably via cooperation of a plurality of collar or collar portions and such that the respective and preferably two arcuate portions generally circumscribe a transport roller when the base is secured thereto. Discrete brush assemblies are preferably provided in a plurality of inner and outer radial dimensions such that roller brush assemblies as disclosed herein can be used with transport rollers of various outer radial dimensions.

A toothbrush is provided. The toothbrush includes a handle, a bristle containing component coupled to a first end of the handle, and an actuation mechanism connected to the bristle containing component. The actuation mechanism includes an actuator lever fixedly secured to a periphery of the flexible membrane and an actuator switch coupled to an end of the actuator lever. configured, upon actuation, to allow the actuator lever to translate and deform the flexible membrane along the length of the handle. The actuator lever is configured, upon actuation, to allow the actuator lever to translate and deform the flexible membrane along the length of the handle.

Cleaning tools and associated methods for cleaning lumens of medical devices are provided. An embodiment of the cleaning tool comprises an elongated core, two scrubbers attached to the elongated core, and a wiper attached to the elongated core. The wiper is axially disposed between the two scrubbers. The cleaning tool may be used to clean the lumen prior to decontamination of the lumen.

A toilet brush comprises a handle and a brush head. A backbone core is coupled to the handle. An inner support piece is further coupled to the backbone core and to the brush head. The handle further comprises an attachment area and the brush head further includes a scraping feature.

A surface cleaning apparatus can include a housing adapted to move across a surface to be cleaned, and an edge cleaning brush provided on the housing. The edge cleaning brush can include an attachment hub connectable with a drive coupling for rotating the brush, a cleaning implement configured to contact the surface to be cleaned, and a tensioner hub applying downward force onto the cleaning implement. Drive couplings for the edge cleaning brush are also disclosed, such as drive couplings including a worm and belt that are indirectly drive via a brushroll.

A retractable interdental brush includes an interdental brush, a retractable mechanism, and a handle. The retractable mechanism is configured to drive the interdental brush to extend from the handle to clean a gap between teeth. After use, the interdental brush is retracted into an accommodation space of the handle through the retractable mechanism. The interdental brush may be a built-in interdental brush. When the built-in interdental brush is used for cleaning, a brush body may be first retracted into an elbow at a front end of a delivery device, an outlet of the elbow is pressed against the gap between teeth to push the brush body, and a working portion of the brush body and enters into the gap between teeth to clean the gap between teeth, thereby resolving a problem with existing interdental brush that easily stabs gingival tissue due to a difficulty of alignment with the gap between teeth.

Systems, methods, and new file formats are provided for printing 3D microstructures. In some implementations, a new file format is provided that defines 3D objects by a wireframe model expressed as a collection of wires. Because wires and their parameters are defined within the new file format, objects may be processed more efficiently and quickly to support 3D rendering operations. Such methods may be used to print new articles, such as eyelashes, bushes, swabs and other novel items.
