A rotary scrubber apparatus, the apparatus includes a tube member having a helical slot, an attachment end portion, a holding end portion, and an internal cavity extending therethrough. A biasing element is contained within the internal cavity of the tube member. A following pin extends through the helical slot. The following pin has an external portion that engages a handle, and an internal portion that engages the biasing element. A scrubbing element is coupled with the attachment end of the tube member and rotationally fixed therewith. When the handle is pressed towards the attachment end and the handle is prevented from rotating about the tube member, the tube member rotates to rotate the scrubber element. The apparatus thereby provides rotational movement of the scrubber to be generated from only linear movement of the handle provided by a user.

The present invention relates to a brushing guide elastic toothbrush comprising: a toothbrush head having bristles provided on the outer circumferential surface of one side in the longitudinal direction; a toothbrush handle connected to the rear end of the toothbrush head in the longitudinal direction and extending in one direction such that a user can hold the toothbrush handle by hand; and an elastic rotation restoring part provided between the toothbrush head and the toothbrush handle and allowing rotation of the toothbrush handle and rotation of the toothbrush head based on the rotation of the toothbrush handle. When force is applied to the toothbrush handle by the user such that the toothbrush handle rotates in one direction with respect to the longitudinal direction while the bristles are pressed and in close contact with the user's teeth or gums, the elastic rotation restoring part allows the rotation of the toothbrush handle and stores a rotational force generated by the toothbrush handle, and when the pressure contact of the bristles is released from the user's teeth or gums while a rotational force generated by the toothbrush handle is stored in the elastic rotation restoring part, the elastic rotation restoring part may provide the stored rotational force to the toothbrush head such that the teeth or gums can be cleaned by the bristles while the toothbrush head rotates in the same direction as the toothbrush handle.

A solar panel cleaning brush assembly including a trolley frame having parallel first and second side frame members. A first guide member is connected to the first side frame member. A second guide member is connected to the second side frame member. A first belt rotatably disposed about a perimeter of the first guide member directly contacts a first array edge of a solar panel array. A second belt rotatably disposed about a perimeter of the second guide member directly contacts a second array edge of the solar panel array. At least one brush set is connected to the trolley frame, the at least one brush set having multiple fixed, non-rotating brushes each frictionally contacting and spanning across a module face of individual ones of multiple solar panel modules defining a solar panel array.

A sweeper machine comprises a support frame, a machine body, and a garbage collection case. The support frame includes two fixing arms. The machine body is disposed between and mounted to the two fixing arms. The garbage collection case is inserted to the rear side of the machine body. Each fixing arm includes a driving wheel. The machine body includes a body casing and a roll brush. The roll brush is disposed inside the body casing. The body casing includes an opening. The lower part of the roll brush is exposed from the opening. Two first connection holes are respectively formed on two ends of the body casing. Each driving shaft extends out of the fixing arm and penetrates one connection hole. Two ends of the roll brush are respectively firmly connected with the two driving shafts separately penetrating the two first connection holes.

A kit comprising a base module, a plurality of rodded oral care devices, a hanger, a support element that hangs from the hanger, and a non-electronic multi-input multi-display counter is disclosed herein. The support element for supporting each rodded oral care device of the plurality of devices. Embodiments relate to fluid loading/unloading mechanism involving elements of the base module. The non-electronic multi-input multi-display counter may be used to track different types of oral care operations, e.g. at least some of which are performed using the base module and/or a rodded oral care device. Related methods are disclosed.

Fluid applicators and systems having a moving mechanism, for example a slider mechanism, and a flexible shaft having a stationary member, a movable member and a brush member, the brush member attached between the stationary member and the movable member via at least two pivots, the movable member further attached to the moving mechanism.

A rotary push broom provides a geometry between the centerline of the broom's wheels and the centerline of the broom's cylindrical brush that allows the vertical height of the cylindrical brush relative to that of the wheels to be adjusted as the frame rotates. The broom includes a support stand that allows the broom to be stored in a way that does not put the broom's weight on the brush. The broom also includes a ratchet gear system so that the broom rotates along with the wheels when the broom is operated in a forward sweeping direction and spins independent of the wheels when the broom is operated in a rearward direction. The gear system should be arranged so that the cylindrical brush rotates slower than the wheels in the sweeping direction. The support stand can be integrated with an endplate that accommodates the wheel connection and ratchet gear system.
