A stress control brush includes a handle, a brush head, and a feedback component. The brush head is pivoted on the handle, and the brush head is pivotable relative to the handle in an angular range. The feedback component is installed between the handle and the brush head. The feedback component is resilient and has a protruding state and a breakdown-sunken state. The feedback component is pressed by the brush head and in the breakdown-sunken state when the brush head is pivoted relative to the handle, and a feedback is provided by the feedback component.

A system and method for collection of non-metallic and metallic foreign object debris (FOD) is disclosed. The foreign object debris system consists of one or more debris collection modules and can be deployed in various width configurations. Debris collection modules can be pulled, pushed, attached to moving equipment, vehicles or to a tow trailer to provide motion. Each pickup module consists of a frame, a debris bin area, a brush, one or more rigid ramp(s) with replaceable tip(s). Multiple debris collection modules can be connected to form a wider or narrower sweeping width. As the foreign object debris system travels forward, debris travels up the tip(s) and ramp(s) and is deposited into a debris bin.

A noise-reduced and quietly operable electrically driven toothbrush with a technically simple basic structure includes a handle portion at a first end of the toothbrush and a head portion at a second end of the toothbrush. The head portion is detachably connectable to the handle portion. A rotatable drive shaft extends at least in the head portion and defines a first longitudinal axis. An electric drive unit directly or indirectly rotates the drive shaft. A bristle holder is pivotally mounted to the head portion and is drivingly engaged by an end of the drive shaft.

A brushing accessory, including a first member, including a hole and a brush fixed thereto, and a second member, including a motor for rotating a first elliptic gear, a second elliptic gear interlaced with the first elliptic gear, and a pin extending from the second elliptic gear into the hole of the first member, thereby moving the brush on a user's body as a function of changing locations of the pin, the locations changing as a function of the interlacing of the elliptic gears.

A fluid dispensing scrubber includes a shaft having a first end and a second end; a fluid inlet configured to receive a first fluid from an external source; a reservoir configured to store a second fluid; a valve assembly configured to selectively mix the first fluid and the second fluid; a scrubbing head supported adjacent the first end of the shaft, the scrubbing head including a brush and a motor operable to rotate the brush; a battery pack supported adjacent the second end, the battery pack operable to provide power to the motor; and a dispensing nozzle configured to selectively dispense one or both of the first fluid and the second fluid, the nozzle supported on an exterior surface of the scrubbing head.

An ergonomic sweeping device that can be used with one hand while providing a user with proper biomechanical alignment and support, which can reduce muscular strain, fatigue, and the potential for injury.

A hair care appliance is provided. The hair care appliance includes a handle and a body coupled to the handle via a rotational hinge joint. The body can be movable via the rotational hinge joint between a straight configuration in which the body is aligned with a longitudinal axis of the handle and a bent configuration in which the body extends along an axis transverse to the longitudinal axis of the handle. A fluid flow path extends between an inlet in the handle and an outlet in the body. The hair care appliance can be operated with minimal loss of fluid flow in either the straight configuration and the bent configuration. The hair care appliance includes a fan assembly in the handle and a heater assembly in the body that are positioned to create a balanced center of mass of the hair care appliance when operated by a user.

This application provides an oscillating toothbrush, including a brush head, a brush handle, an oscillating base mounted on the brush handle, and an oscillating rod that connects the brush head to the oscillating base, and the oscillating base includes a first hinge base hinged to the brush handle in a first direction, a second hinge base hinged to the brush handle in a second direction, and a fixing shaft mounted on the first hinge base in the second direction, with the first direction being perpendicular to the second direction. In the present application, the oscillating base is arranged to include the first hinge base hinged to the brush handle in the first direction and the second hinge base hinged to the brush handle in the second direction. When the brush head is subjected to an external force, the oscillating rod may drive the first hinge base to oscillate on the brush handle in the first direction. In one embodiment, the oscillating rod oscillates on the fixing shaft in the second direction to further drive the second hinge base to oscillate on the brush handle in the second direction. Therefore, with the oscillation of the first hinge base and the second hinge base, the brush head is allowed to oscillate at multiple angles under external forces in different directions, to improve the comfort of toothbrushing.

The present invention provides a mechanically-actuated livestock brush apparatus, for tending to animal livestock, whose movement can be actuated and also controlled via a mechanical means. In an embodiment, the mechanical means may include a spring device. The mechanical means should be such that it provides sufficient resistance for a controlled movement of the brush apparatus preventing infinite movement, e.g., infinitely rotating/revolving, while also provides sufficient resistance such that when an animal pushes against it, it does not move freely or randomly, but puts resistive pressure against the animal's body for a good scratch. Also, the brush apparatus has a universal motion, allowing it to move in multiple directions.
