Abstract

A water purifier includes a flow meter for measuring the cumulative flow of water through a water purification cartridge The flow meter has an indicator portion that rotates in response to increasing cumulative flow and a graduated portion rotating about the same axis as that of the indicator portion. The graduated portion includes an insertion groove for manually rotating the graduated portion in order to reset the flow meter. Because the flow meter has few part, the body of the water purifier can be made compact and its cost reduced.
