The Innovative Design of an Outdoor Centrifugal Water Filter

A portable water filter, which is composed of an outer barrel, a transmission, and an inner barrel, is powered by centrifugal force. The transmission, comprising a shaft and a pedal, is housed at the bottom of the outer barrel. The shaft rotates when a force is applied to the pedal. The inner barrel is housed inside the outer barrel. The end of the shaft penetrates the bottom of the outer barrel and is fixed to the bottom of the inner barrel. The inner barrel contains a multi-layered filter pad. With this design, when unfiltered water is poured into the inner barrel, the pedal will rotate the inner barrel through the attached shaft when pedaling starts. Water, in turn, is filtered through the multi-layered filter pad, achieving the goal of water filtration.
