The invention discloses a filling port structure of an expansion water tank. The filling port structure is fixed to the expansion water tank and assembled with the kettle cover, the filling port structure comprises a filling port body, a filling port cavity is formed in the upper portion in the filling port body, a plurality of floating ball plugging openings are formed in the lower portion in the filling port body along the circle center, and the lower portion of each floating ball plugging opening is communicated with a floating ball plugging cover assembling cavity. The lower portion of the floating ball blanking cap assembly cavity is communicated with the water outlet cavities, each water outlet cavity is communicated with one of the multiple cavities in the expansion water tank, a floating ball is arranged below each floating ball blanking cap, the upper portion of the floating ball blanking cap is in interference fit with the floating ball blanking cap assembly cavity, the lower portion of the floating ball blanking cap is located in the water outlet cavities, and the floating balls are arranged in the floating ball blanking cap. According to the water buoyancy principle, all the cavities can be automatically closed after filling is completed. And each cavity is provided with a corresponding exhaust port communicated with the kettle opening, so that independent exhaust of each cavity is realized. According to the invention, the manufacturing cost is reduced, and the structure is standardized.
