A toothbrush is provided. The toothbrush may include a brush head having a first brush and a second brush. Each of the first brush and second brush may include bristles extending radially from first ends of the first brush and second brush. The first brush and second brush may rotate in opposite directions along rotational axes parallel to a longitudinal axis of the toothbrush to brush away from the gums of a user and assist with implementing a rolling brushing method.

A removable brush head for a personal groom device, the removable brush head having a stationary portion, wherein the stationary portion is annular and includes a plurality of outwardly-extending brush bristles. The removable brush head also includes a movable portion positioned within the stationary portion, wherein the movable portion is configured to at least partially rotate relative to the stationary portion, and further wherein the movable portion includes a plurality of outwardly-extending brush bristles. Additionally, the removable brush head includes a locking collar, wherein the locking collar is slidably couplable to the stationary portion so as to axially retain the movable portion within the stationary portion while allowing the movable portion to at least partially rotate relative to the stationary portion.

A rotatable body brush, preferably driven by an electric motor, has pivoted segments in the brush or working element. The segments swing outwardly when the user desires a larger-diameter brush, and can be retained inwardly when a smaller brush, such as a face brush, is desired.

A manual toothbrush having oral hygiene elements arranged in polygons with an oral hygiene element at each apex, and having plural polygons nested within each other. The oral hygiene elements may be bristles, which may be of two different types, or elastomer elements and may contain tooth-polishing additive. The toothbrush head surface may be flat or may have its region distal from the handle angled up.

A toothbrush includes a handle and a head mounted to the handle. In one aspect, the head may extend from a proximal end to a distal end along a longitudinal axis, the head having a base portion formed of a rigid plastic material and a flexible portion formed of an elastomeric material, a first longitudinal section of the flexible portion spaced apart from the base portion by a gap. The flexible portion of the head may have an upper surface and an opposing lower surface such that within the first longitudinal section of the flexible portion the upper surface and the lower surface are substantially planar and parallel to one another. Furthermore, tooth cleaning elements may be secured to the flexible portion of the head by in-molded technology to extend from the upper surface of the flexible portion

Handle of toothbrush including a central region to locate fingers, and an index finger locator zone. The central region including thumb zone and two other finger locator zones, for receiving the thumb and middle finger on opposite sides of the central region of the toothbrush handle. Toothbrush having such handle and attachment configured for attachment to the handle of a toothbrush wherein the attachment including thumb zone and two other finger locator zones, for receiving the thumb and middle finger on opposite sides.

A retractable broom comprises a handle section and a broom head section. The handle section includes a retractable handle with one or more movable locking joints including locking mechanisms that are configured to connect and interlock the sections of the retractable handle together. An arm, including a stationary locking joint, having a locking mechanism, at one end of the arm connects and interlocks the retractable handle to the arm. The other end of the arm is fixedly attached to a brush head. The broom head section also comprises a retractable cover and third locking joint with a locking mechanism that connects and interlocks the retractable cover to the arm at two or more positions, with at least one position causing the retractable cover fully cover the brush head and a second position causing the retractable cover to at least partial uncover the brush head.

A broom bracket for a push broom which serves to provide strength between the connection of the handle and the broom block while inhibiting the rotation of the handle relative to the block and any loosening of a threaded connection therebetween.

A handheld appliance having a body and an attachment, the body includes an attachment mechanism having a slot and an actuator, the attachment including a protrusion adapted to engage with the slot wherein the actuator has a first position and a second position and the actuator is moved from the first position towards the second position as the protrusion engages with the slot. In the first position the actuator may at least partially obscures the slot. The actuator includes a surface which may interact with the protrusion when the protrusion engages with the slot. The surface may be adapted to at least partially define the slot at or near the second position. When the protrusion is at a pre-determined position within the slot, the actuator may return towards the first position. The actuator may be biased into the first position.

A cleaning mechanism having a self-locking function, comprising a cleaning rack, a cleaning member and a sweeping member, adapted for use on photovoltaic panel, is disclosed. The cleaning rack comprising a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod which are detachably connected. The cleaning member being detachably mounted between the first connecting rod and the third connecting rod, used for stripping off adhesive materials on photovoltaic panel; the sweeping member used for sweeping adhesive materials away from photovoltaic panel. Cleaning mechanism further comprises a cleaning member power unit, detachably connected with the cleaning member and used for driving cleaning member to rotate; and cleaning member power unit comprises a self-locking device, used for preventing cleaning member from idling, and sundries are prevented from being twisted thereon and meanwhile unnecessary wear between cleaning member and photovoltaic panel can be reduced.
