The invention discloses a water purification device with multiple parallel filter elements. The water purification device comprises a base, a cartridge body fixedly connected to the base, a plurality of filter element components mounted between the cartridge body and the base, brush components mounted on the outer sides of the filter element components, and driving mechanisms mounted on the filter element components and used for driving the brush components and the filter element components. The water purification device with multiple parallel filter elements is capable of completely washing ceramic filter elements; the dirt is accumulated in a conical groove; the water flushes the sludge out of a water purifier when turning on an undrinkable water outlet faucet; the purpose of automatically washing the ceramic filter elements by means of power generated by water pressure can be achieved; driving clamping teeth are formed in one part of an incomplete gear; when the driving clamping teeth of the incomplete gear and driven clamping teeth are meshed for rotating; the driven clamping teeth only drive the brush components corresponding to the driven clamping teeth to clockwise rotate and wash the ceramic filter elements, so that the purpose of not excessively washing the ceramic filter elements can be achieved.
