Abstract
A liquid circulator is described that is configured to circulate liquids such as water, chemical mixtures, suspensions and the like. The liquid circulator includes an oscillation shaft, a circulation assembly mounted to the oscillation shaft, and a head unit located above the circulation assembly with a motor having an output shaft in driving engagement with the oscillation shaft. The liquid circulator may be devoid of a processor controlling operation of the liquid circulator. The circulator can also include a rotary to oscillation drive mechanism between the output shaft and the oscillation shaft that is configured to convert rotation of the output shaft into clockwise and counterclockwise oscillation of the oscillation shaft. In another example, an automatic clutch mechanism can be provided between the output shaft and the oscillation shaft.
