Abstract

A water inlet assembly with a spring flow stabilizing device for improving hot water output includes a base, an inner tube, an outer tube and a sealing gasket. The base includes an internally threaded countersunk hole at the top, an inner sleeve and an externally threaded interface at the lower end. The sealing gasket is sleeved on the outer tube, and the axial lower end is in contact with the bottom plate of the internally threaded countersunk hole. It also includes a flow stabilizing spring, which cooperates with the radial water outlet hole on the outer tube. It has the function of blocking and slowing down the impact force of the incoming tap water, so that the incoming water naturally falls to the bottom, and the hot water is squeezed from the bottom of the inner tank and rises slowly, so as to achieve the purpose of improving the hot water output rate. After the water storage electric heater uses a water inlet assembly with a spring flow stabilizing device, the hot water output rate is greatly improved. At the same time, the utility model utilizes the elastic function of the spring under the impact of water pressure to automatically clean the dirt stuck on the outside of the water inlet assembly at any time to ensure the smoothness of water inlet.
