A hand pump cleaning brush is provided. In an implementation, a cleaning brush converts liquid cleaner in a reservoir to a lather of cleaning foam through mechanical action provided by the user. An example cleaning brush may include a handle connected to a removable bristle block. A liquid reservoir is contained within the handle and stores the liquid cleaner. The reservoir is connected to a piston driven pump and/or valve that produces foam, for example, by aeration with ambient air through a mesh. A finger trigger provides pumping force. In an implementation, the foaming pump or valve draws air and liquid cleaner into a chamber and dispenses these to the brush head through a fine mesh screen, which aerate the liquid cleaner into a foam at the brush head. A rotary locking device with a push button can allow the head to swivel on the handle.

A brush for back surface treatment (BST) is provided. The brush includes a base portion and a brushing portion. The brushing portion is connected to the base portion. The brushing portion has a plurality of gutters disposed on a surface away from the base portion, in which at least one of the gutters has at least one open end located at least partially on a perimeter of the surface.

The present invention relates to a vehicle engine-washing apparatus and a washing method using the washing apparatus, and more particularly, to a vehicle engine-washing engine for washing the inside of vehicle engine, which apparatus includes a hollow operation tube; a guide part having a body inserted into a tip portion of the operation tube and formed with a through-hole, and a leading-in tube formed on the body in such a manner as to communicate with the through-hole; a holder fitted on and fixed to an outer circumferential surface of the operation tube and having a tapered part and an engagement panel formed at an end of the tapered part; an end cap fitted to a terminal end portion of the operation tube and formed with an operation hole; an operation rod inserted through the operation hole of the end cap and having a coupling protrusion formed at one end of the operation rod and a coupling groove formed at the other end; a hollow connection socket disposed in the operation tube, the other end portion of the socket being fitted on the coupling protrusion introduced into the operation tube; and a washing rod having an inserted protrusion formed at one side thereof which is inserted into one end portion of the connection socket, and a brush part provided at the other side, whereby effects are obtained that washing of the inside of the engine is allowed without having to separate the engine, thereby significantly reducing cost and time for maintenance, and anyone can conveniently perform the washing.

An extendable battery operated scrubber brush with interchangeable brush heads is provided. The scrubber brush includes a battery operated scrubber brush having an extendable handle and a plurality of interchangeable brush heads, each having different body cleaning materials thereon, and a battery charging docking station. The handle is extendable via an elongated member that is slidably disposed in an interior volume thereof. The handle includes a proximal end and a distal end that includes a drive shaft for removably receiving an interchangeable brush head thereon. The drive shaft is coupled to an electric motor disposed in the handle that rotates the drive shaft and drives an interchangeable brush head mounted thereon. The proximal end includes a port for receiving an electrical connector disposed in the docking station and one or more activation switches for activating the electric motor and driving the drive shaft.
