The invention belongs to the technical field of water pumps, and particularly relates to a noise reduction structure of a water pump, which comprises a pump body, a partition plate is arranged in the pump body, a high-pressure cavity and a low-pressure cavity are formed on two sides of the partition plate, and an impeller chamber connected with the high-pressure cavity and the low-pressure cavity is formed below the partition plate; the impeller is arranged in the impeller chamber, and the impeller is connected with a power assembly for driving the impeller to rotate; wherein a plurality of blades are arranged on the outer edge of the impeller, spacing parts are formed between the adjacent blades, and the spacing size of at least one spacing part is different from the spacing sizes of the other spacing parts. Due to the fact that at least one spacing part with the spacing size different from that of the other spacing parts exists in the impeller, when the blades located on the two sides of the spacing part ar
