The present invention provides a coil brush having one or more brush heads with any brush head parallel to any other. The brush heads may have a head base, a bristle slide or guide, and bundles or groups of straight and/or angled bristles, which may be interspersed in different arrangements in a head base of the head brush head, allowing for a variety of brushing planes. The coil brush may further comprise a rear mount handle or a detachable handle that allow the user to adjust the position of the brush to better access and clean coils in hard to reach places. The bristle slide allows the user to control the stiffness of the bundles of bristles by controlling the spreading of the bristles. This invention allows the brushing of coils in heating ventilation and air conditioning equipment at a variety of angles from a variety of coil access points.

A back-flushing plate (4) of a multifunctional oral care tool is provided at a back end of brush heads (1) and has an end portion lower than an end portion of the brush heads (1). A pair of brush heads (1) is driven to rotate by a pair of transmission rods (5), such that the brush heads produce a powerful suction flow. Sucked water splashes onto the back-flushing plate and generate a powerful flush flow, thereby attains a goal of flushing the oral waste away. It solves a problem of deep cleaning of furs and also solves a problem of waste liquid, such as tooth-brushing foam, remaining in an oral cavity.

A method of cleaning and polishing a backside surface of a semiconductor wafer is provided. The method includes placing an abrasive brush, comprising an abrasive tape wound around an outer surface of a brush member of the abrasive brush, on the backside surface of the semiconductor wafer. The method also includes rotating the brush member to polish the backside surface of the semiconductor wafer by abrasive grains formed on the abrasive tape and to clean the backside surface of the semiconductor wafer by the brush member which is not covered by the abrasive tape.

Embodiments set forth a cleaning brush handle that includes a head region that includes one or more brush apertures, where each brush aperture is configured to receive one replaceable brush. The brush apertures may be orthogonal to the brush handle, or, in the alternative, may be at an angle in the longitudinal direction, the transversal direction, or both. The brush includes a nominally round or hex-shaped shank that is inserted into the brush aperture. The brushes are held in place via a suitable mounting mechanism, such as a threaded insert that receives a thumbscrew or a bushing with a threaded hole that receives a thumbscrew. The mounting mechanism provides for easy insertion, rotation, removal, and replacement of the brushes. The mounting mechanism provides for rotating the brushes, in small increments, through a 360 range, for more even brush wear and longer brush life, relative to conventional cleaning brushes.

A multipurpose cleaning device is disclosed which is designed to achieve a high degree of surface coverage in any direction with each brush sweep so that cleaning surfaces, such as vehicles, may be performed fast and easy. The shape of the brush head provides maximum area coverage on each sweep and minimizes the tendency of the brush head from tipping during a sweep when connected to a main handle and a pivoting head feature minimizes the need of bending. Embodiments includes versions optimized for both washing that including channels for the introduction of water and liquid soap as well as to received drying members.

A brush has a brush head having a main body and bristles extending therefrom, with the main body having a cylindrical shaft with a rounded cylindrical circumference. Semispherical bodies having bristles extending therefrom are adapted to be removably secured to axially opposite ends of the main body. These bristles radially extend 360 around both the cylindrical circumference of the main body and each semispherical body. A handle for the brush and an adapter for coupling the brush to a handle, are also provided.

The surface of teeth to clean as shown (FIG. 1) and the type of toothbrushes as shown (FIG. 2, FIG. 3, FIG. 4) are closely related. Table 1 (Cleaning Effectiveness of Toothbrushes) in page 7 shows the relationship. For four section surfaces (S1, S2, S3, S4), Type-B toothbrush is best because of its effective and timesaving feature. For one section surface (S5), Type-A toothbrush is best because no other is effective. For the last remaining section surface (S6), Type-C toothbrush is best because no other is effective.

A cleaning brush includes a rigid bottom base wall portion, side wall portions extending from opposite sides of the bottom base wall portion, a first rigid top wall portion extending from an upper end of one side wall portion, and a second rigid top wall portion extending from an upper end of the other side wall portion. A slot is provided between facing ends of the top wall portions which extends between first and second ends of the cleaning brush. A first set of first bristles extends from the bottom base wall portion, and second and third sets of bristles extend from the top wall portions. Free ends of the bristles may touch each other, be spaced from each other, or may extend past each other.

A dental cleaning system comprises a first wall element for mounting against the inner, lingual, tooth surfaces of one or both jaws and a second wall element for mounting against the outer, facial, tooth surfaces of said one or both jaws. A drive mechanism couples the first and second wall elements, and imparts a drive vibration of the first and second wall elements towards each other and apart from each other.

A specialized scrubbing brush for cleaning high rise windows and other hard surfaces. The specialized scrubbing brush includes a pair of cleaning pads, one or more attachment gaps between the each of the cleaning pads, an axis of rotation, one or more water pipes, one or more water channels, a plurality of water holes and an interface surface between the pair of cleaning pads. Further, cleaning equipment is provided which includes the specialized scrubbing brush along with a pair of oscillating arms with a sliding yoke, a pair of rod shaped guide rails, an oscillation mechanism and a rotation mechanism. The scrubbing brush cleans automatically and is able to scrub a surface from corner to corner and is able to change from one scrubbing pad to another without human intervention.
