This utility model discloses a disinfection device for domestic water, relating to the technical field of domestic water disinfection devices. It includes an outer shell assembly composed of a stainless steel cylinder, a flange, and a connecting channel. Disinfection components are disposed on the inner and outer sides of the stainless steel cylinder, and these components are used to disinfect the water flowing through the inner side of the stainless steel cylinder. This utility model achieves water flow along a spiral trajectory and is disinfected by ultraviolet radiation by setting up the disinfection components. Compared to traditional straight flow, the spiral flow extends the water flow distance, increasing the exposure time for microorganisms. Furthermore, the centrifugal force generated by the swirling flow causes repeated exchange of water from the pipe wall to the center, allowing microorganisms to be more evenly exposed to the high-intensity ultraviolet radiation area. This reduces radiation dead zones, extends exposure time, and increases the probability of microorganisms contacting ultraviolet radiation, further improving the disinfection effect and power of domestic water.
