[0022] Please refer to Figures 1-4 As shown in the drawings, a water outlet sealing structure comprises a silica gel sealing piece 1, an intermediate connecting piece 2 and a fixing seat 3, the silica gel sealing piece 1 is installed in the fixing seat 3 through the intermediate connecting piece 2;

[0023] The upper end of the intermediate connecting piece 2 is an insertion end, and the lower end is provided with a first annular groove 4, the silica gel sealing piece 1 is sleeved on the lower end of the intermediate connecting piece 2 and extends inwardly at the position corresponding to the first annular groove 4 to be provided with a first annular protrusion 5, and the silica gel sealing piece 1 is connected and fixed with the intermediate connecting piece 2 through cooperation of the first annular protrusion 5 and the first annular groove 4;

[0024] The fixing seat 3 is cylindrical, and the inner side wall of the fixing seat 3 is provided with a second annular groove 6, and the upper end of the intermediate connecting piece 2 is provided with a second annular protrusion 7 corresponding to the second annular groove 6, and the intermediate connecting piece 2 is installed in the fixing seat 3 through cooperation of the second annular protrusion 7 and the second annular groove 6; when the silica gel sealing piece 1 is installed in the fixing seat 3 through the intermediate connecting piece 2, the outer side wall of the silica gel sealing piece 1 is tightly combined with the inner side wall of the fixing seat 3. The beneficial effects of the present application are that through the above structure design, the sealing structure of the cup cover arranged at the water outlet 14 can effectively fix the silica gel sealing piece 1 in the horizontal and vertical directions, greatly reducing the possibility of the silica gel sealing piece 1 falling off, even in the case of long-term use or being impacted by external force, the silica gel sealing piece 1 can be firmly installed in the fixing seat 3, thereby providing a safer and more reliable use experience for users, especially children, and avoiding the risk of children mistakenly swallowing due to falling.

[0025] In one of the embodiments, the lower end of the intermediate connector 2 is provided with a limiting protrusion 8, and the silica gel sealing member 1 is provided with a receiving cavity 9, the lower end of the intermediate connector 2 is arranged in the receiving cavity 9, and the silica gel sealing member 1 abuts against the limiting protrusion 8 when being extruded and deformed. When the silica gel sealing member 1 is deformed due to a large pressure, the limiting protrusion 8 can provide additional support and limiting effect for the silica gel sealing member 1. For example, when the cup contains high-temperature liquid, the internal pressure increases, and the silica gel sealing member 1 may be deformed to a large extent, but the limiting protrusion 8 can prevent it from being deformed too much. While the silica gel sealing member 1 is tightly attached to the water outlet 14 to ensure the sealing performance through a certain deformation, the risk of the silica gel sealing member 1 falling off due to deformation is further reduced, and the adaptability of the sealing structure in complex use environment is improved.

[0026] In one of the embodiments, the silica gel sealing member 1 is provided with an extension 10 extending outward along the edge, and the extension 10 abuts against the open end surface of the fixed seat 3 to limit the silica gel sealing member 1.
