Patent attributes
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.
