A method of delivering a glutinous substance to a workpiece from an end-effector comprises using the end-effector to rotate a brush relative to the workpiece about a rotational axis. The method also comprises, while rotating the brush relative to the workpiece about the rotational axis, urging the glutinous substance from the end-effector through a channel of a body of the brush from an axial inlet of the channel to an outlet of the channel, into contact with a thatch of bristles of the brush. Additionally, the method comprises using the end-effector to position the brush relative to the workpiece such that the glutinous substance in contact with the thatch is delivered onto at least a first surface and a third surface of the workpiece.

A hand attachable animal washing apparatus, attachable upon the hand of a user, is provided enabling singlehanded control of waterflow and application of water into the coat of an animal. Control of waterflow though a molded body member is enabled by operation of a compressible portion disposed to control a valve assembly disposed interiorly within the molded body member. A proximal arced edge is disposed projected rearwardly from the molded body member and curved downward to direct waterflow away from a user operating the device, particularly when the device is elevated above a user, as when washing a large animal such as a horse, for example. A user may thereby control and apply water to an animal with one hand while securing and comforting the animal with the other hand.

A surface attachable washing apparatus is provided to enable easy control of water flow through a molded body member. A valve assembly, disposed interiorly within the body member, is actuated by simple depression of an overlying portion of an obverse surface of the molded body member, to toggle a valve assembly between each of a closed position and an open position. Water flow is therefore controllable by manual pressure to alternately emit and prevent water flow sprayed through each of a plurality of outlets. At least one suction cup enables selective positioning of the molded body member upon a surface distally situated relative to an existing water outlet to which the apparatus is connected. A user may therefore position the apparatus at a desired height in the bath room, for example, to correspond with a child who can then easily control of the water flow during bath time.

A hand attachable animal washing apparatus, attachable upon the hand of a user, enables singlehanded control of water flow and application of water into the coat of an animal. Control of water flow though a molded body portion is effective by singlehanded operation of a valve assembly disposed interiorly within the molded body portion. A user is enabled to open and close the valve assembly by compressing a compressible portion disposed proximally overlying the user's palm when wearing the apparatus upon one hand. A user may thereby control and apply water applied to an animal with one hand while securing and comforting the animal with the other hand.

A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

A brush for delivering a glutinous substance to a workpiece from an end-effector is disclosed. The brush comprises a body having a rotational axis. The body comprises a first end, a second end, opposite the first end, and a channel, comprising an axial inlet and an outlet. The axial inlet is at the first end of the body and is coaxial with the rotational axis. The brush also comprises bristles, extending from the body so that the bristles are not parallel to the rotational axis of the body.

A toothbrush including a chassis assembly, an output shaft configured to connect to a brush head and extending at least in part through a portion of the chassis assembly, a power train assembly operably connect to the output shaft, where the power train assembly oscillates the output shaft. The toothbrush also includes a fluid connector operably coupled to the chassis assembly and fluidly coupled to the output shaft via the power train assembly. The fluid connector rotates 360 degrees relative to the chassis assembly.

Presented is an electric toothbrush system capable of being operated in a rinsing mode to rinse the mouth with clean water, a vacuuming mode for sucking out oral gunk left in the mouth after brushing is done besides used for cleaning teeth and gums. The electric toothbrush system is configured to illuminate the interior of the mouth of the user, and is provided with the capability to decontaminate the water used for rinsing the mouth.

A disclosed example brush for dispensing multiple fluids during cleaning of a surface includes: an annular porous polymeric brush body configured to dispense a first fluid through the brush; and a first annular plate mechanically coupled to the brush body, wherein the plate includes: a channel to direct the first fluid from an inlet of the channel to the brush body; and a plate annulus aligned with a brush annulus of the brush body, such that the brush annulus and the plate annulus direct a second fluid from an inlet to the surface.

A brushing device including a motor having an eccentric drive shaft, an output shaft operably connected to the motor, and a power train assembly coupled between the eccentric drive shaft and the output shaft. The power train converts rotation of the eccentric drive shaft into an oscillating movement of the output shaft. The power train includes one or more conservation features that absorb energy when the output shaft rotates in a first direction and reapply energy to the output shaft when it rotates in a second direction.
