A cleaning tool includes a holding rod and a cleaning assembly that is disposed on at least one end of the holding rod, wherein a connecting assembly is disposed between the holding rod and the cleaning assembly. The connecting assembly includes a controlling member having an engaging portion and a pressing portion. When the holding rod is connected to the cleaning assembly, the engaging portion corresponds to an engaged portion on an inner wall of a connecting tube of the cleaning assembly, so that the holding rod and the cleaning assembly are locked to each other, and the pressing portion is located out of the connecting tube. When the pressing portion is pressed, the engaging portion is disengaged from the engaged portion, thereby allowing the holding rod to be disengaged from the cleaning assembly.

A system for the application of mascara. The system has a container and an applicator wand. The applicator wand has a handle that extends along a central axis. A wand shaft extends from the handle and hold a brush head. The brush head includes a brush held in an articulable mount. The articulable mount orients the brush in a position where the central axis of the handle intersects the center line of the brush at a point between the ends of the brush. The brush is biased to a first angle of inclination. The articulable mount provides a hinge joint between the brush and the wand shaft. The hinge joint enables the brush to temporarily rotate about the hinge joint away from its first angle of inclination and into a second angle of inclination to pass into or out of the access opening of the container.

A reconfigurable brush includes an elongated brush head extending between brush-head first and second ends and a brush handle extending between handle proximate and distal ends. The brush-head first end is mounted to the handle distal end for rotation about a brush-head rotation axis between opposed first and second angular orientations and axial displacement along the brush-head rotation axis between opposed axial first and second positions. The first and second angular orientations are defined such that the brush-head second end is disposed, respectively, (i) rearwardly of the brush-head first end and the handle distal end and (ii) forwardly of the brush-head first end and the handle distal end. The axial first and second positions correspond to the handle being, respectively, (a) locked in one of the first and second angular orientations and (b) unlocked to allow rotation between the opposed first and second angular orientations.

Disclosed herein are a mop mitt for car washing, a mop body for car washing, and a method of manufacturing a mop mitt for car washing. According to one embodiment of the present invention, there is provided a mop mitt for car washing, the mop mitt including: a first surface sewn in the state in which an outer peripheral portion has been folded inward, and forming one surface of a pocket shape having one open side; and a second surface extending from the first surface, rotated around a central portion, and facing the first surface; wherein the first and second surfaces are sewn together on both sides of thereof, so that the mop mitt for car washing is gripped through an insertion portion having one open side.

Apparatus and associated methods relate to a fibrillous abrasive crevice cleaner (FACC). In an illustrative example, a fibrillous abrasive tip may be made of a continuous combination of steel wool and wire. For example, the FACC may include a twisted multistrand handle extending from a distal end to a proximal end along a longitudinal axis. The FACC may include a continuous fibrillous mass fixedly coupled about the distal end of the twisted multistrand handle, such that the fibrillous mass forms a knot distal to the proximal end of the twisted multistrand handle. For example, the FACC may include a proximal end of the fibrillous mass captured between the twisted multistrand handle. The formed knot around the distal end of the twisted multistranded handle and the fibrillous mass being entwined into the handle may, for example, advantageously resist decoupling of the fibrillous mass from the twisted multistrand handle.

The invention provides for an oral treatment unit, or an assembly of a plurality of oral treatment units, for confining an electromagnetic field having a frequency in the range of 100 kHz to 300 MHz and adapted to be inserted into an oral cavity, which may form part of an oral cleaning device in combination with a base unit, including a first cleaning element coupled to the oral treatment unit. The oral treatment unit further includes a material structure coupled to the oral treatment unit adapted to receive an initial electromagnetic field and output a focused electromagnetic field, wherein the material structure has a passive electromagnetic field focusing function, which focuses the received initial electromagnetic field in the near-field region of the material structure. A further aspect of the invention provides for an oral treatment unit, or an assembly of a plurality of oral treatment units, for confining and modulating an electromagnetic field having a frequency in the range of 1 MHz to 300 GHz and adapted to be inserted into the mouth, which may form part of an oral cleaning device in combination with a base unit, including a first cleaning element coupled to the oral treatment unit. The oral treatment unit further comprises an electromagnetic field focusing element adapted to receive an electromagnetic field having an initial frequency and output a focused electromagnetic field. The electromagnetic field focusing element comprises a first material structure having a first passive electromagnetic field focusing function, which confines the modulated electromagnetic field at a given distance from the first material structure by performing one or more of: an attenuation rate control function in the near-field region of the first material structure; or a propagation direction modification function on the electromagnetic field. The electromagnetic field focusing element has a modulation function that modulates the confined electromagnetic field, thereby generating a modulated electromagnetic field.

A flexible composite torsion shaft for attachment to a drive shaft includes an elongated core element having a circular cross section. A reinforcement comprising at least one polymer layer and multiple layers of reinforcing-fiber wound around the core element inside the at least one polymer layer. Each reinforcing-fiber layer is wound around the core element at a winding angle in a range of 40° to the hoop winding angle, depending on a width of a reinforcing-fiber being wound, relative to a longitudinal direction of the core element. At least one reinforcing-fiber-layer is wound at an opposite angle from another reinforcing-fiber layer inside the at least one polymer layer. The winding angle increases as an average layer diameter of reinforcing-fiber insider the at least one polymer layer increases.

A cleaning device for cleaning inner surfaces of an object such as a bottle or vase. A device includes a shaft, a slidably coupled runner, a hub, arms pivotally coupled to the hub, stretchers, cleaning heads attached to the tips of the arms, and arm rod coupled to the runner. The arms can include wiping material along their length. When retracted, the device can be inserted into an object. Pushing on the rod leads to extension of the arms. The extended arms can be held in place by a securing means such as a set screw. The device can then be moved rotationally, translationally or both relative to the object. The securing means can then be released, and the arms can be retracted by pulling the rod. The device can be removed from the object, and the cleaning heads can be removed.
