The invention relates to a water-purifying flower sprinkler with double filter elements. The water-purifying flower sprinkler includes a hollow handle, the handle is internally provided with the first filter element and the second filter element, and the first filter element and the second filter element are tightly connected by an opposite fixed structure. The opposite fixed structure is provided with a water pipe hole connected with a water outlet of the first filter element; the side wall of the water pipe hole is provided with a plurality of water outlets, and the water outlets are communicated with parallel multi-circulation pipelines located at the inner wall of the second filter element; the water inlet end of the water-purifying flower sprinkler is communicated with the inlet of the first filter element and with a ring-shaped space between the first filter element and the inner wall of the handle at the same time, and the ring-shaped space is communicated with a water inlet of the second filter element; the water outlet of the second filter element and the multi-circulation pipelines are converged at the position of a water flow guide pipe, water flows out of the same outlet to water outlets of the water-purifying flower sprinkler. The double filter elements can independently work at the same time, when one of the double filter elements is out of order, the other one can still play a role in water purifying.
